    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 ...

    Magnetic resonance angiography (MRA) is commonly used to follow up patients after endovascular treatment for intracranial aneurysms. Magnetic resonance artefacts from coil constructs may impair image quality and jeopardise the evaluation of the effectiveness of treatment and review of adjacent vasculature. We present here a technical note on the usage of Barricade coils recently introduced at our institution. The MRA artefacts associated with these coils may make it impossible to ascertain aneurysm closure and anatomy. Hence these patients would need to be recalled for digital subtraction angiograms for a complete neuroradiological follow-up. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  4. Pepper spray projectile/disperser for countering hostage and barricade situations

    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.

    Sehmel, G.A.

    1980-01-01

    Airborne plutonium could result from resuspension of nuclear-weapons-testing stratospheric fallout deposition. To determine this possible resuspension at the Hanford site, two field experiments between April 12 to june 29, 1976 and August 12, 1976 to January 11, 1977 were conducted near the Prosser Barricade in the Hanford area about 19 to 22 km southeast (140 0 to 160 0 ) of the fuel-processing areas. The primary objective of these experimentss was to determine if stratospheric fallout resuspension was reflected by airborne plutonium concentrations increasing with increasing wind speed. A secondary objective was to confirm the source of the airborne plutonium by determining the plutonium-240 isotopic content or the plutonium-240/plutonium-239-mass ratio. Stratospheric fallout can be identified by the ratio of 240 Pu to other plutonium isotopes in surface soils. Plutonium was transported during southwesterly winds during the two study periods at the Prosser Barricade. Airborne 239 240 Pu concentrations varied as powers of wind speed (U):U -0 2 to U 7 8 . The airborne solids content ranged from 6 x 10 -8 to 1.7 x 10 -6 μCi/g. The 240 Pu isotopic content ranged from 5.6 to 8.1 atom percent and the 240 Pu/ 239 Pu mass ratio ranged from 0.065 to 0.089. The estimated fraction of stratospheric fallout plutonium in these samples was less than 0.24. The remaining airborne plutonium was probably of Hanford origin. Airborne plutonium probably represents resuspension of plutonium from undetermined sites by mechanisms and events not clear at present. An increasing airborne plutonium concentration with increasing wind speed might be expected for an upwind resuspension source(s). However, the geographical source(s) location was not investigated in this study

    On February 15, 2017, a DESHF-STO HPFC (health physics field coordinator) was asked by an NEN-1 employee if they could move an instrument, a radiation dosimetry system, from A166A to another lab at TA-35 Building 2. The HPFC walked the job down and discovered the instrument was connected to power. The instrument had not been connected to power previously. See photo 1. The instrument is located within an RCA (radiological control area). Entry to connect the instrument to power the instrument requires contacting RP. RP personnel had not been contacted as required as stated in the RCA posting.

  11. Moving the Barricades to Physical Activity: A Qualitative Analysis of Open Streets Initiatives Across the United States.

    Ciclovía, or Open Streets initiatives, are events where streets are opened for physical activity and closed to motorized traffic. Although the initiatives are gaining popularity in the United States, little is known about planning and implementing them. The goals of this paper are to explore the development and implementation of Open Streets initiatives and make recommendations for increasing the capacity of organizers to enhance initiative success. Phenomenology with qualitative analysis of structured interviews was used. Study setting was urban and suburban communities in the United States. Study participants were organizers of Open Streets initiatives in U.S. cities. Using a list of 47 events held in 2011, 27 lead organizers were interviewed by telephone about planning, implementation, and lessons learned. The interviews were digitally recorded and transcribed. A phenomenologic approach was used, an initial coding tool was developed after reviewing a sample of transcripts, and constant comparative coding methodology was applied. Themes and subthemes were generated from codes. The most common reasons for initiation were to highlight or improve health and transportation. Most initiatives aimed to reach the general population, but some targeted families, children, or specific neighborhoods. Getting people to understand the concept of Open Streets was an important challenge. Other challenges included lack of funding and personnel, and complex logistics. These initiatives democratize public space for citizens while promoting physical activity, social connectedness, and other broad agendas. There are opportunities for the research community to contribute to the expanse and sustainability of Open Streets, particularly in evaluation and dissemination.

    The co-administration of multiple drugs (polypharmacy) is the single most common cause of adverse drug events in the older population, and residents of long-term care facilities (LTCFs) are at particularly high risk of medication harm. 'Deprescribing'--the withdrawal of an inappropriate medication with goal of managing polypharmacy and improving outcomes--may improve the quality of life of LTCF residents. The RELEASE study sought to explore perceptions of medication use and the concept of deprescribing in LTCFs. Focus groups and interviews were conducted with General Practitioners (GPs), pharmacists, nursing staff, residents and their relatives within three LTCFs in the Illawarra-Shoalhaven region of NSW, Australia. Audiotapes were transcribed verbatim and, using the Integrative Model of Behaviour Prediction as a framework, thematic analysis of transcripts was conducted using QSR NVivo 10. Participants acknowledged the burden of too many medications (time to administer, physical discomfort, cost), yet displayed passivity towards medication reduction. Residents and relatives lacked understanding of medicine indications or potential harms. Willingness to initiate and accept medication change was dependent on the GP, who emerged as a central trusted figure. GPs preferred 'the path of least resistance', signalling systems barriers (poor uniformity of LTCF medical records, limited trained LTCF personnel); time constraints (resident consultations, follow-up with specialists and family); and the organisation of care (collaborating with LTCF staff, pharmacists and prescribing specialists) as obstacles to deprescribing. Targeted engagement is required to raise awareness of the risks of polypharmacy in LTCFs and encourage acceptance of deprescribing amongst residents and their relatives. GPs are integral to the success of deprescribing initiatives within this sector.

  13. 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.

    1994-04-01

    A 240-m deep borehole (Yakima Barricade borehole), located on the US Department of Energy`s (DOE) Hanford Site, was drilled as part of a DOE research program to investigate microbial processes in deep subsurface environments and to evaluate geochemical and geohydrological controls on subsurface microorganisms. A combustible gas was detected during drilling of the Yakima Barricade borehole (YBB). Once it was established that the major combustible gas was H{sub 2}, a series of tests were performed to evaluate the process by which H{sub 2} occurred within the borehole. This paper presents evidence for the generation of H{sub 2} in boreholes during percussion drilling below the water table and discusses mechanism of H{sub 2} generation and their implications for subsurface microbial processes.

    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.

    Transportation via Roads should only be used for safely commuting from one place to another. In 2015, when 1.5 Million people, across the Globe started out on a journey, it was meant to be their last. The Global Status Report on Road Safety, 2015, reflected this data from 180 countries as road traffic deaths, worldwide. In India, more than 1.37 Lakh[4] people were victims of road accidents in 2013 alone. That number is more than the number of Indians killed in all the wars put together. With these disturbing facts in mind, we found out some key ambiguities in the Indian Road Traffic Management systems like the non-adaptive nature to fluctuating traffic, pedestrians and motor vehicles not adhering to the traffic norms strictly, to name a few. Introduction of simple systems would greatly erase the effects of this silent epidemic and our Project aims to achieve the same. It would introduce a pair of Barricade systems to cautiously separate the pedestrians and motor vehicles to minimise road mishaps to the extent possible. Exceptional situations like that of an Ambulance or any emergency vehicles will be taken care off by the use of RFID tags to monitor the movement of the Barricades. The varied traffic scenario can be guided properly by using the ADS-B (Automatic Detection System-Broadcast) for monitoring traffic density according to the time and place.

    Full Text Available The effects of wavy geometry on natural convection in an enclosure with two wavy vertical walls and filled with fluid saturated porous media are investigated numerically by using finite element method. The wavy enclosure is transformed to a unit square in the computational domain and the finite element formulations are solved in terms of ξη-coordinate based on iterative method. In order to investigate the effects of interested parameters, the values of wave amplitude (λ = 0.05 and 0.1 and number of undulations (n = 1 and 2 are chosen with constants Ra = 105, Da = 10−3, and Pr = 0.71. It is found that the increase in number of undulations has small effect on natural convection inside the enclosure whereas the increase in wave amplitude reduces the strength of convection because higher wave volume plays a barricade role.

    Microbial Fuel Cells (MFCs) are the promising devices which can produce electricity by anaerobic fermentation of organic / inorganic matter from easily metabolized biomass to complex wastewater using microbes as biocatalysts. MFC technology has been found as a potential technology for electricity generation and concomitant wastewater treatment. However, the high cost of the components and low efficiency are barricading the commercialization of MFC when compared with other energy generating systems. The performance of an MFC is largely relying on the reactor design and electrode materials. On the way to improve the efficiency of an MFC, tremendous exercises have been carried out to explore new electrode materials and reactor designs in recent decades. The current review is excogitated to amass the progress in design and electrode materials, which could bolster further investigations on MFCs to improve their performance, mitigate the cost and successful implementation of technology in field applications as well.

    1977-07-01

    Plutonium resuspension results are summarized for experiments conducted at Rocky Flats, onsite on the Hanford reservation, and for winds blowing from offsite onto the Hanford reservation near the Prosser barricade boundary. In each case, plutonium resuspension was shown by increased airborne plutonium concentrations as a function of either wind speed or as compared to fallout levels. All measured airborne concentrations were below maximum permissible concentrations (MPC). Both plutonium and cesium concentrations on airborne soil were normalized by the quantity of airborne soil sampled. Airborne radionuclide concentrations in μCi/g were related to published values for radionuclide concentrations on surface soils. For this ratio of radionuclide concentration per gram on airborne soil divided by that for ground surface soil, there are eight orders of magnitude uncertainty from 10 -4 to 10 4 . Horizontal plutonium fluxes on airborne nonrespirable soils at all three sites were bracketed within the same three to four orders of magnitude from 10 -7 to 10 -3 μCi/(m 2 day) for plutonium-239 and 10 -8 to 10 -5 μCi/(m 2 day) for plutonium-238. These are the entire experimental base for nonrespirable airborne plutonium transport. Airborne respirable plutonium-239 concentrations increased with wind speed for a southeast wind direction coming from offsite near the Hanford reservation Prosser barricade. Airborne plutonium fluxes on nonrespirable particles had isotopic ratios, 240 Pu/ 239+240 Pu, similar to weapons grade plutonium rather than fallout plutonium. Resuspension rates were summarized for controlled inert particle tracer simulant experiments. Wind resuspension rates for tracers increased with wind speed to about the fifth power

    2017-06-01

    Introduction While the concept of community resilience is gaining traction, the role of spontaneous volunteers during the initial response to disasters remains controversial. In an attempt to resolve some of the debate, investigators examined the activities of a spontaneous volunteer group called Nafeer after the Sudan floods around the city of Khartoum in August of 2013. Hypothesis Can spontaneous volunteers successfully initiate, coordinate, and deliver sustained assistance immediately after a disaster? This retrospective, descriptive case study involved: (1) interviews with Nafeer members that participated in the disaster response to the Khartoum floods; (2) examination of documents generated during the event; and (3) subsequent benchmarking of their efforts with the Sphere Handbook. Members who agreed to participate were requested to provide all documents in their possession relating to Nafeer. The response by Nafeer was then benchmarked to the Sphere Handbook's six core standards, as well as the 11 minimum standards in essential health services. A total of 11 individuals were interviewed (six from leadership and five from active members). Nafeer's activities included: food provision; delivery of basic health care; environmental sanitation campaigns; efforts to raise awareness; and construction and strengthening of flood barricades. Its use of electronic platforms and social media to collect data and coordinate the organization's response was effective. Nafeer adopted a flat-management structure, dividing itself into 14 committees. A Coordination Committee was in charge of liaising between all committees. The Health and Sanitation Committee supervised two health days which included mobile medical and dentistry clinics supported by a mobile laboratory and pharmacy. The Engineering Committee managed to construct and maintain flood barricades. Nafeer used crowd-sourcing to fund its activities, receiving donations locally and internationally using supporters

    Core hole DC-8 was completed in August, 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 Scisson, Inc. furnished the engineering, daily supervision of the core drilling activities, and geologic core logging for hole DC-8. Core hole DC-8 is located on the Hanford Site near the Wye Barricade and 50 feet northwest of rotary hole DC-7. The Hanford Site vation coordinates for DC-8 are North 14,955.94 feet and West 14,861.92 coordinates for DC-8 are North 14,955.94 feet and West 14,861.92 mean sea level. The purpose of core hole DC-8 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 and cross-hole seismic shear and pressure wave velocity studies with rotary hole DC-7. The total depth of core hole DC-8 was 4100.5 feet. Core recovery exceeded 97 percent of the total footage cored.

    Today's smartphones/phablets/tablets are equipped with cameras that have enabled people to capture their favorite moments. However, images or videos taken at public places using inexpensive low-resolution cameras are often degraded by the presence of occlusions such as fences/barricades. In order to reconstruct a fence-free high-resolution image, we use a video of a scene captured by panning a hand-held camera and model the effects of various degradations. Initially, we obtain the spatial locations of fences by semantic segmentation and subsequently estimate the subpixel motion between the degraded low-resolution frames. The unknown high-resolution de-fenced image is modeled as a nonlocal discontinuity-adaptive Markov random field (NL-DAMRF) and its maximum a posteriori estimate is obtained by minimizing an appropriate objective function. We propose a nonlocal extension of DAMRF prior to preserve high-frequency information in the reconstruction process. Specifically, we use the graduated nonconvexity algorithm to minimize the proposed nonconvex energy function. Experiments with both synthetic and real-world data demonstrate the efficacy of the proposed algorithm.

    Since 1984, a recuperation program of soils of sedimentary origin has been developed in the farm of Armero of Tolima University, which up to this year (1996) has already shown many a good positive result. To attain such a remarkable effect in the highly deteriorated soils of this farm, it was decided to develop a project for their conservation consisting of the building of terraces, live and dead hedges and barricades, as well as the planting of fruit and forest trees so that, through a well planned methodology, the community members may learn to design, build, maintain and evaluate practical work oriented towards their own know-how and especially to the recuperation of unproductive areas, together with their integration, at due time, with the land and cattle activity. The soil conservation project began in November, 1983, and today, 12 years after having it been worked out, maintained and evaluated, we can see a land wholly recovered, with abundant native vegetation ready for production, mainly with the setting of perennial crops. Bearing in mind these successful results, our recommendation is to continue to implement this project in the different areas where the setting of soil conservation works is necessary, in order that the benefits obtained may be multiplied through the installment of easy and, especially, very economical set-ups

    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. 

  16. Application of United States Department of Transportation regulations to hazardous material and waste shipments on the Hanford site

    All hazardous material and waste transported over roadways open to the public must be in compliance with the U.S. Department of Transportation (DOT) regulations. The DOT states that the hazardous material regulations (HMR) also apply to government-owned, contractor-operated (GOCO) transportation operations over any U.S. Department of Energy (DOE) site roadway where the public has free and unrestricted access. Hazardous material and waste in packages that do not meet DOT regulations must be transported on DOE site roadways in a manner that excludes the public and nonessential workers. At the DOE Richland Field Office (the Hanford Site), hazardous material and waste movements that do not meet DOT requirements are transported over public access roadways during off-peak hours with the roadways barricaded. These movements are accomplished using a transportation plan that involves the DOE, DOE contractors, and private utilities who operate on or near the Hanford Site. This method, which is used at the Hanford Site to comply with DOT regulations onsite, can be communicated to other DOE sites to provide a basis for achieving consistency in similar transportation operations.

    To investigate availability of deep freeze stored allogenic tendon with sheath grafting in repairing the tendon and sheath defect in the II area of flexor digitorum tendon. 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. 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. 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.

  18. The skin microbiome: Is it affected by UV-induced immune suppression?

    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.

  20. Access road from State Route 240 to the 200 West Area, Hanford Site, Richland, Washington: Environmental assessment

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-01

    The US Department of Energy (DOE) proposes to construct an access road on the Hanford Site, from State Route (SR) 240 to Beloit Avenue in the 200 West Area. Traffic volume during shift changes creates an extremely serious congestion and safety problem on Route 4S from the Wye barricade to the 200 Areas. A Risk Evaluation (Trost 1992) indicated that there is a probability of 1.53 fatal accidents on Route 4S within 2 years. To help alleviate this danger, a new 3.5-kilometer (2.2-mile)-long access road would be constructed from Beloit Avenue in the 200 West Area to SR 240. In addition, administrative controls such as redirecting traffic onto alternate routes would be used to further reduce traffic volume. The proposed access road would provide an alternative travel-to-work route for many outer area personnel, particularly those with destinations in the 200 West Area. This proposal is the most reasonable alternative to reduce the problem. While traffic safety would be greatly improved, a small portion of the shrub-steppe habitat would be disturbed. The DOE would offset any habitat damage by re-vegetation or other appropriate habitat enhancement activities elsewhere on the Hanford Site. This Environmental Assessment (EA) provides information about the environmental impacts of the proposed action, so a decision can be made to either prepare an Environmental Impact Statement or issue a Finding of No Significant Impact.

    Recent genetic evidence suggests that the most important environmental influences on normal and pathologic development are those that are not shared by siblings in the same family. We sought to determine the relationship between differences in parenting styles and depressive symptoms and antisocial behavior in adolescence, and to compare the influence of these nonshared experiences with genetic influences. We studied 708 families with at least two same-sexed adolescent siblings who were monozygotic twins (93 families), dizygotic twins (99 families), ordinary siblings (95 families), full siblings in step families (181 families), half siblings in step families (110 families), and genetically unrelated siblings in step families (130 families). Data on parenting style were collected by questionnaire and by video recording of interaction between parents and children. Almost 60% of variance in adolescent antisocial behavior and 37% of variance in depressive symptoms could be accounted for by conflictual and negative parental behavior directed specifically at the adolescent. In contrast, when a parent directed harsh, aggressive, explosive, and inconsistent parenting toward the sibling, we found less psychopathologic outcome in the adolescent. Parenting behavior directed specifically at each child in the family is a major correlate of symptoms in adolescents. Furthermore, harsh parental behavior directed at a sibling may have protective effects for adolescents, a phenomenon we call the "siblin barricade."

  5. Effect of the chemical structure of anion exchange resin on the adsorption of humic acid: behavior and mechanism.

    2015-01-01

    Polystyrenic (PS) anion-exchange resin and polyacrylic (PA) anion-exchange resin were used to investigate the effect of resin chemical structure on the adsorption of humic acid (HA). Due to the rearrangement of HA to form layers that function as barricades to further HA diffusion, PS resin exhibited 12.4 times slower kinetics for the initial adsorption rate and 8.4 times for the diffusion constant in comparison to that of the PA resin. An HA layer and a spherical cluster of HA can be observed on the surface of the PS and PA resins after adsorption, respectively. The considerable difference in HA adsorption between the PS and PA resins was due to the difference in molecule shape for interaction with different resin structures, which can essentially be explained by the hydrophobicity and various interactions of the PS resin. A given amount of HA occupies more positively charged sites and hydrophobic sites on the PS resin than were occupied by the same amount of HA on the PA resin. Increased pH resulted in an increase of HA adsorption onto the PA resin but a decrease in adsorption onto PS resin, as the non-electrostatic adsorption led to electrostatic repulsion between the HA attached to the resin and the HA dissolved in solution. These results suggest higher rates of adsorption and higher regeneration efficiency for interaction of HA with more hydrophilic anion exchange materials. Copyright © 2014 Elsevier Inc.

    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.

    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.

    Cemented paste backfill (CPB) is a sustainable backfilling technique used in underground mining operations that ensures ground stabilization. The technique uses mine waste for filling the voids created by underground mining. Compared to conventional backfilling technologies, CPB has the advantage of rapid transport to the stopes; shorter turn-around cycle time; elimination of the drainage barricades in the CPB-filled stopes; and diversion of mine waste from surface disposal sites to underground stopes. Partial replacement of Portland cement with fly ash or ground blast furnace slag, can significantly reduce production costs and improve the performance of typical CPBs. This paper studied the effect of fly ash on the hydration process in CPB during the early stages of hydration using non-destructive, electromagnetic (EM) wave-based techniques. The study showed that the use of fly ash in Portland cement delayed the hydration process, and that the delay was proportional to the replacement level. At later onset times, the fly ash particles enhanced the hydration process by providing additional ions that contributed to the formation of hydration products and ultimately increased the mechanical strength of CPB. The EM test results on CPB obtained in the controlled laboratory environment were compared with in situ test results obtained in an actual backfilled test stope. The EM-wave based techniques were found to be sensitive to paste composition, including binder content, binder type and water content of the paste. 16 refs., 3 tabs., 6 figs.

    Full Text Available Althusser's work arrived just when the disintegrating liberal consensus was shaking the ivory towers of the university. Students protested the war in Vietnam as well as the policies of the university. Althusser offered an understanding of this corrupt world and its distorted self-image. These theories provided an exciting new totalization in which life had meaning and intellectuals, a vital role. In literary studies, students and lecturers assumed that works of literature were anti-scientific, preservers of the status quo, without genuine knowledge. Disillusioned, these students and lecturers condemned Literature as an institution and ignored the individual work. To stop teaching the dominant ideology, they found redemption through abstraction—general principles, abstract structures. Academics found it attractive to raise barricades in the mind, not the street. Althusserian ideas showed lecturers and students that what was thought to be a purely literary or factual matter of aesthetic appreciation was really ideological and political, but the arrogance of the Althusserians, who recognized no theory before Althusser and no value in empirical experience, offended potential allies.

    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.

    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. - Highlights: • Iron oxide nanoparticles offer various modalities in the field of cancer theranostics. • Magnetic field guided targeting and local hyperthermia are two well known modalities in cancer therapy. • These techniques need further investigations to curtail certain limitations manifested. • This review emphasizes the recent efforts carried out to counteract the drawbacks.

    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.

    Full Text Available South Africa has recently experienced a series of public protests. The common element is that violence is becoming evident in these protests. This article uses the June 2016 protests in the city of Tshwane as an example to address the root causes of such protests. On 20 June 2016, the African National Congress (ANC announced that the city of Tshwane mayoral candidate for the 3 August 2016 municipal elections in South Africa is the former public works minister and ANC National Executive Committee member, Thoko Didiza. Consequently, public protests in the city of Tshwane emerged immediately after this announcement. These public protests were very violent, such as protesters killed one another, burned buses, looted shops and barricaded roads. The root causes of these violent protests are identified as factionalism, tribalism, sexism, economic exclusion and patronage politics. The purpose of this article is a practical theological reflection on the root causes of June 2016 protests in the city of Tshwane. The main aim of this article is a practical theological solution to the general problem of violent protests.

    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.

    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.

  17. Remembrances of Empires Past

    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.

    In Pakistan, the three days of Islamic festival of Eid ul Azha (Eid) are characterized by millions of livestock sacrifices and availability of countless breeding resources for insects of forensic importance. Thus during Eid, December, 2008, in a Pakistani village observing 70 sacrifices, we examined postmortem insect attractions on various sacrificial products (from 23 animals), i.e., blood pools, meat, hides/skins, bones, offal and real time insect succession on goats' offal at five dump sites. Thirty five insect species were collected from 14 indoor and outdoor sites. Offal at the dump sites attracted most insect species both by taxa and in numbers, followed by hides in the court yards, meat (40-70 kg/animal) in kitchens and blood pools in the court yards. Synanthropic calliphorids and muscids were found to be exclusive indoor "first and only arrivals" in comparison to a diverse array of first day insect arrivals at dump sites including calliphorids, sarcophagids, muscids, sphaerocerids, sepsids, empidids, gryllids and formicids. Though burial is usually considered as a barricade between most insect species and carrion yet dump site A with an early burial but also earliest insect colonization showed the fastest rate of decomposition. No vertebrate scavenging at any of the offal dump sites perhaps showed their private feeding inclination, thus implying that in times of mass slaughters most of the dumped winter carrion products in human vicinities are either consumed by insects and/or are buried. Here we also suggest a high rate of fly dispersal during Eid which if true has consequences for forensic investigations in Muslim populace areas especially during the Eid.

    2011-10-01

    The aim of the current study is to outline the state of affairs related to pollutants and slaughtering techniques of syngas that result both from waste thermal treatment by gasification. The study starts by a review permitting to classify the gasification techniques applied to waste thermal treatment. This review leads to distinguish between auto-thermal and allo-thermal equipments. Furthermore, are described, in this first part, the general principles and parameters of functioning and adjustment of the factors characterizing the thermal treatment in reducing atmosphere. It is also about the composition of the syngas products according to the different driving behaviours of gasifiers. Finally, we state succinctly, on one hand, the possible promotion procedures in the frame of syngas development and, on the other hand, the thresholds that we ought to reach in order to make this promotion achievable. The second part of the study deals with the characteristics of the pollutants located in the syngas. This description took the shape of a detailed index card where pollutants are classified into minority components (including those of pollutants, those of gaseous and those of particulates) according to their concentrations, to their driving behaviours and to their thermochemical conditions of formation (temperature, pressure, response-type agents, atmosphere...). In the last part, we discuss the current and the considered types of slaughtering devices in reducing atmosphere in relation with their performance in slaughtering and regarding the departure point of syngas promotion ways. Finally, are exposed the key postures and the barricades within those technologies. Hereupon, research axes are proposed. (authors)

    The experiences gained from several Integrated Gasification Combined Cycle (IGCC) demonstration plants operating in the US and Europe facilitate commercial success of this advanced coal-based power generation technology. However, commercialization of coal-based IGCC technology in the West, particularly in the US, is restricted due to the low price of natural gas. On the contrary, in China--the largest coal producer and consumer in the world--a lack of natural gas supply, strong demand for air pollution control and relatively low costs of manufacturing and construction provide tremendous opportunities for IGCC applications. The first Chinese IGCC demonstration project was initiated in 1994, and other potential IGCC projects are in planning. IGCC applications in re-powering, fuel switching and multi-generation also show a great market potential in China. However, questions for IGCC development in China remain; where are realistic opportunities for IGCC projects and how can these opportunities be converted into commercial success? The answers to these questions should focus on the Chinese market needs and emphasize economic benefits, not just clean, or power. High price of imported equipment, high financing costs, and the technical risk of first-of-a-kind installation barricade IGCC development in China. This paper presents preliminary technical and economic assessments for four typical IGCC applications in the Chinese marketplace: central power station, fuel switching, re-powering, and multi-generation. The major factors affecting project economics--such as plant cost, financing, prices of fuel and electricity and operating capacity factor--are analyzed. The results indicate that well-proven technology for versatile applications, preferred financing, reduction of the plant cost, environmental superiority and appropriate project structure are the key for commercial success of IGCC in China

    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.

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

    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.

    Microdevices prepared in a silicon substrate have been widely used in versatile fields due to the matured silicon-based microfabrication technique and the excellent physical properties of silicon material. However, the high thermal conductivity of silicon restricts its application in most thermal microdevices, especially devices comprising different temperature zones. In this work, a parylene-filled-trench technique was optimized to realize high-quality thermal isolation in silicon-based microdevices. Parylene C, a heat transfer barricading material, was deposited on parallel high-aspect-ratio trenches, which surrounded the isolated target zones. After removing the remnant silicon beneath the trenches by deep reactive ion etching from the back side, a high-quality heat transfer barrier was obtained. By using narrow trenches, only 5 µm thick parylene was required for a complete filling, which facilitated multi-layer interconnection thereafter. The parylene filling performance inside the high-aspect-ratio trench was optimized by two approaches: multiple etch–deposition cycling and trench profile controlling. A 4 × 6 array, in which each unit was kept at a constant temperature and was well thermally isolated individually, was achieved on a silicon substrate by using the present parylene-filled-trench technique. The preliminary experimental results indicated that the present parylene-filled-trench structure exhibited excellent thermal isolation performance, with a very low power requirement of 0.134 mW (K mm 2 ) −1 for heating the isolated silicon unit and a high thermal isolation efficiency of 72.5% between two adjacent units. Accompanied with high-quality isolation performance, the microdevices embedded the present parylene-filled-trench structure to retain a strong mechanical connection larger than 400 kPa between two isolated zones, which is very important for a high-reliability-required micro-electro-mechanical-system (MEMS) device.

    Bresje led to barricades. After the attack, the Italian KFOR troops are responsible for security of the Serbian population in Kosovo Polje, because the Serbs no longer had confidence in British KFOR troops. One of the reasons for shelling the market place was also intended to prevent the creation of a large Serbian enclave in Kosovo Polje and the surrounding area and that the Serb population from such a region displace. Consequences of shelling the market place are numerous: loss of 3 lives, wounding about 40 people, to cancel the agreement on the integration of Serbian and Albanian municipal authorities in Kosovo Polje, a sense of fear, inequality, insecurity and anxiety among the Serbian population, but also better protection of the Serbian population in Kosovo Polje and the environment.

    We present the long-term results of a new modification of endoscopic treatment of vesicoureteral reflux involving concomitant injection of autologous blood following the standard hydrodistention injection technique to prevent bulking agent leakage immediately after the procedure. A total of 341 children underwent endoscopic implantation of dextranomer/hyaluronic acid for vesicoureteral reflux. A subset of 171 patients underwent hydrodistention autologous blood injection, while 170 underwent classic hydrodistention injection. Frequency of symptomatic urinary tract infection after endoscopic treatment was recorded. Success was defined as absence of vesicoureteral reflux on postoperative voiding cystourethrography. A total of 523 ureters in 214 girls and 127 boys were treated. In patients undergoing hydrodistention autologous blood injection mean age was 39.48 months, mean maximal reflux grade was 3.02 and success rate was 93.6% after the first injection (98.0% in patients with grade II, 92.1% with grade III, 93.3% with grade IV and 85.7% with grade V reflux). In patients who underwent classic hydrodistention injection mean age was 36.12 months, mean maximal reflux grade 3.05 and success rate was 81.8% after the first injection (91.5% in patients with grade II, 89.4% with grade III, 74.4% with grade IV and 44.4% with grade V reflux). The success rate was significantly higher (p = 0.001) in patients undergoing hydrodistention autologous blood injection vs classic hydrodistention injection. Of the patients 1.7% in the hydrodistention autologous blood injection group and 2.9% in the classic hydrodistention injection group reported symptomatic urinary tract infection during followup. Immediate injection of autologous blood following dextranomer/hyaluronic acid injection to create a blood clot and barricade against bulking agent leakage is more effective than pure dextranomer/hyaluronic acid implantation. This novel modification stabilizes the subureteral implant mount and

    Full Text Available Feuerbach clearly states that Christian theology relates negatively in face of nature.  Religious disregard or devaluation of nature lead to consequences for the judgement of human nature by theology, for the latter condemns also the natural-sensitive dimension of man’s nature, and, in the face of it, glorifies the spirit. Due to the very fact that nature gives expression to objectivity, necessity, corporality, sensibility, it is the negative, so to speak, a proof for the limits of interiority, religious feelings, that is, a true barricade against illusion of a supernatural existence.  From this Christian view point it should, therefore, be cleared, denied.  Feuerback argues that God (the almighty, the sublime essence that was created by religious folly is only a gostly representation by humankind, a subjective konstruktion by man, lacking all nature’s frontiers and restrictions, and the Christian religion assisting man as a tool by means of which he tries do get rid of nature.
    Feuerbach deixa claro que a teologia cristã se relaciona negativamente ante a natureza. A depreciação ou desvalorização religiosa pela natureza tem consequências para o julgamento da natureza humana por parte da teologia, pois esta condena também a dimensão natural-sensível da natureza do homem e, frente a esta, enaltece o espírito. Precisamente porque a natureza expressa objetividade, necessidade, corporeidade, sensibilidade, é ela o negativo, por assim dizer uma prova dos limites da interioridade, do sentimento religioso, isto é, a barreira concreta que se opõe à ilusão de uma existência sobrenatural. Deste ponto de vista cristão, ela deve, portanto, ser eliminada, negada. Feuerbach argumenta que Deus (o todo supremo, a essência sublime, o qual a fantasia religiosa criou, é apenas uma representação fantasmagórica do gênero humano, uma construção subjetiva do homem, abstraída de todas as

    Full Text Available “So what?” Bożena Keff, Magda Szcześniak, Tomasz Tomasik & Błażej Warkocki in a conversation with Anna Zawadzka In April 2013, the Polish Press Agency published an article in which Elżbieta Janicka proposed a new interpretations of Stones on the barricades. 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.   „No i co z tego”.

    To evaluate rhegmatogenous retinal detachment (RRD) in eyes with retinoblastoma after intraarterial chemotherapy (IAC). Retrospective case series. Chart review. Development of RRD in the IAC era. Of 167 eyes in 157 consecutive patients, mean patient age at diagnosis of retinoblastoma was 19 months. Intraarterial chemotherapy was primary (75/167, 45%) or secondary (92/167, 55%). There were 10 eyes (10/167, 6%) that developed RRD after IAC. The RRD was mostly related to rapid tumor regression with atrophic retinal hole, occurring within one month (n = 8) or 12 months (n = 2) of IAC. Rhegmatogenous retinal detachment was found after primary (6/75, 8%) or secondary (4/92, 4%) IAC. Of primary cases, RRD was found in Group D (1/38 [3%], P = 0.1075) or Group E (5/30 [17%], P = 0.0348). For primary IAC (n = 75 eyes), RRD was found in endophytic (5/22 [23%], P = 0.0073), exophytic (0/29 [0%], P = 0.0760), or combined endophytic/exophytic pattern (1/24 [4%], P = 0.6575). A comparison of eyes with RRD (n = 10) versus without RRD (n = 157) found significant differences including greater mean age at presentation (38 vs. 18 months, P = 0.0522), greater 4-quadrant vitreous seeding (5/10, 50% vs. 27/157, 17%, P = 0.0236), and absence of subretinal fluid (3/10, 30% vs. 102/157, 65%, P = 0.0236). The cause of RRD was tumor regression-related atrophic retinal hole(s) in 7 (7/10, 70%) (unifocal [1/10, 10%] or multifocal [6/10, 60%] holes), cryotherapy-induced single atrophic hole in 2 (2/10, 20%), and single flap-tear from posterior vitreous detachment in one (1/10, 10%). In 4 (4/10, 40%) eyes with RRD, proliferative vitreoretinopathy was noted. The RRD was not related to intravitreal injection in any case, as in primary IAC no case had previous injection and in secondary IAC the injections were performed many months previously. Primary RRD repair involved pars plana vitrectomy in three, scleral buckle without drainage in one, laser barricade in one, and observation in five eyes

    modo conciso y resumido, pero recogida luego en su versión definitiva en el capítulo 6 de su libro Topographie des Fremden, volumen primero de los cuatro de que se compone su magna obra Studien zur Phanomenologie des Fremden, publicada por la editorial Suhrkamp de Frankfurt del Meno en 1997. Queremos agradecer al autor y a la editorial su cortesía al permitir que publiquemos la traducción castellana de ese ensayo. "Thinking Europe at its limits", as proposed in 1992 by a group of philosophers from the University of Strasbourg -Denis Guénoun, Philippe Lacoue-Labarthe, Jean-Luc Nancy, Daniel Payot-, means considering what the "geo-philosophy of Europe" is as an essential question that encompasses all truthful reflection surrounding the idea of Europe. The debate, to which a diverse group of colleagues and friends from different nations were invited, advanced the very possibility of an identification of Europe, together with the profoundness, in other words the very violence that this possibility (or impossibility implies, as confirmed time and again since then by recent and highly topical events. The proposal was everything but futile. Indeed, as is well known and was confirmed by the group itself some months later in July 1993, what is certain is that a storm of  terrible furores broke out and atrocious upheavals were expressed,  both intra- and extra-European, that, if nothing else, urge us to consider whether the project of what deserves to be known as a "world"may or may not be confused with the exclusive exportation of what Europe has invented, produced and identified. The future appears to be in the grip of two morbid figures, two symmetrical nightmares: the myth of a homogeneous planet, like a gigantic Europe spreading everywhere; and a confined Europe, imprisoned in its imprecise and uncertain boundaries, a kind of isolating barricade or trenches enabling it to reclusively consume the illusion of its supposed welfare. This deplorable alternative incites
