  4. Safe Fast Reactor Based on the Self-Sustained Regime of Nuclear Burning Wave

    International Nuclear Information System (INIS)

    The results of further development of challenging conception of nuclear fission reactor with the so-called inner safety based on the phenomenon of self-sustained regime of nuclear burning wave proposed by L.P. Feoktistov in 1988 are presented. The initiation and propagation of the nuclear burning wave (NBW) in a fast reactor (FR) are described using the original deterministic multi-group approach based on the solution of the non-stationary two-dimensional diffusion equation for neutron transport, the burn-up equations for fuel components and the equations of nuclear kinetics for precursor nuclei of delayed neutrons. The critical fast reactor of cylindrical form with metal fuel of the UPu cycle that consists of two homogeneous zones along the axial direction is considered. In the first zone (ignition zone) the fuel consists of uranium enriched with plutonium to 10 %. The second zone (breeding zone) is filled with U- 238. Both zones also include the constructional material Fe and the Na or Pb-Bi eutectic coolant. The possibility of creating a self-sustained regime of a running NBW in the critical FR under consideration is demonstrated. Despite forming a large amount of fission products FR is automatically sustained in this regime for a long time in a state close to the critical one due to an intrinsic reactivity feedback governed by the non-linearity of the NBW regime. This negative feedback prevents the reactor from the runaway regime and ensures the stable evolution of the self-organizing NBW regime. The calculation results show a notable stability of the NBW regime towards distortions of the neutron flux. The velocity of NBW propagation strongly depends on the transverse size of FR. For the reactor of 117 cm radius the velocity is about 26 cm/year at steady state of NBW propagation, and in the case of FR of 10 m length the reactor campaign lasts about 30 years without any refueling or fuel shuffling using the natural or depleted uranium as its fuel. It means that

  5. Self-sustained regime of nuclear burning wave in safe fast reactor using mixed Th-U-Pu fuel cycle

    International Nuclear Information System (INIS)

    The results of further development of perspective conception of nuclear fission reactor with the so-called intrinsic safety based on the phenomenon of self-sustained regime of nuclear burning wave are presented. We consider a critical fast reactor of cylindrical form with the metal fuel of the mixed Th-U-Pu cycle and study the possibility of the burning wave propagation in the axial breeding zone containing fuel consisting of 232Th and 238U in different proportions. The presence of the constructional material Fe and the coolant Pb-Bi eutectic in reactor composition is taken into account. The initiation and propagation of the burning wave in a fast reactor of this type are described on the basis of deterministic approach using the non-stationary multi-group diffusion description of neutron transport, taking into account the burn-up of fuel components and the nuclear kinetics for precursor nuclei of delayed neutrons. The calculation results of the space-time evolution of neutron flux and fuel component concentrations are presented for different values of main parameters of the reactor. The possibility of creating a self-sustained regime of a running nuclear burning wave in the critical fast reactor under consideration has been demonstrated for the mixed Th-U fuel. The wave propagation velocity strongly depends on the Th-U ratio and transverse size of the reactor. (authors)

    Full Text Available Several options for designing fast reactors to operate in the Breed-and-Burn (B&B mode are compared and a strategy is outlined for early introduction of B&B reactors followed by a gradual increase in the fuel utilization of such reactors. In the first phase the fast reactor core will consist of a subcritical B&B blanket driven by a relatively small critical seed. As the required discharge burnup/radiation-damage to both driver and blanket fuel had already been proven, and as the depleted uranium fueled B&B blanket could generate close to 2/3 of the core power and will have very low fuel cycle cost, the deployment of such fast reactors could start in the near future. The second phase consists of deploying self-sustaining stationary wave B&B reactors. It will require development of fuel technology that could withstand peak burnups of ~30% and peak radiation damage to the cladding of ~550 dpa. The third phase requires development of a fuel reconditioning technology that will enable using the fuel up to an average burnup of ~50%—the upper bound permitted by neutron balance considerations when most of the fission products are not separated from the fuel. The increase in the uranium ore utilization relative to that provided by contemporary power reactors is estimated to be 20, 40 and 100 folds for, respectively, phase 1, 2 and 3. The energy value of the depleted uranium stockpiles (“waste” accumulated in the US is equivalent to, when used in the B&B reactors, up to 20 centuries of the total 2010 USA supply of electricity. Therefore, a successful development of B&B reactors could provide a great measure of energy sustainability and cost stability.

    DIII-D is making significant contributions to a scientific basis for sustained burning plasma operation. These include explorations of increasingly reactor-relevant scenarios, studies of key issues for projecting performance, development of techniques for handling heat and particle efflux, and assessment of key issues for the ITER research plan. Advanced scenarios are being optimized in DIII-D via experiments to empirically determine the relationship between transport and the current profile, which in turn can provide essential input to inform improvement of the theory-based models that do not currently capture the observed behaviour. Joint DIII-D/JET ρ* scans in the hybrid regime imply Bohm-like confinement scaling. Startup and shutdown techniques were developed for the restrictive environment of future devices while retaining compatibility with advanced scenarios. Towards the goal of a fully predictive capability, the DIII-D program emphasizes validation of physics-based models, facilitated by a number of new and upgraded diagnostics. Specific areas include transport, rotation, energetic particles and the H-mode pedestal, but this approach permeates the entire research programme. Concerns for heat and particle efflux in future devices are addressed through studies of ELM control, disruption avoidance and mitigation, and hydrogenic retention in DIII-D's carbon wall. DIII-D continues to respond to specific needs for ITER. Recent studies have compared H-mode access in several different ion species, identifying not only isotopic, but density, rotation and geometrical dependences that may guide access to H-mode during ITER's non-activated early operation. DIII-D used an insertable module to simulate the magnetic perturbations introduced by one of ITER's three test blanket module sets, demonstrating that little impact on performance is seen at ITER equivalent levels of magnetic perturbation.

  8. Thorium Fuel Options for Sustained Transuranic Burning in Pressurized Water Reactors - 12381

    International Nuclear Information System (INIS)

    As described in companion papers, Westinghouse is proposing the adoption of a thorium-based fuel cycle to burn the transuranics (TRU) contained in the current Used Nuclear Fuel (UNF) and transition towards a less radio-toxic high level waste. A combination of both light water reactors (LWR) and fast reactors (FR) is envisaged for the task, with the emphasis initially posed on their TRU burning capability and eventually to their self-sufficiency. Given the many technical challenges and development times related to the deployment of TRU burners fast reactors, an interim solution making best use of the current resources to initiate burning the legacy TRU inventory while developing and testing some technologies of later use is desirable. In this perspective, a portion of the LWR fleet can be used to start burning the legacy TRUs using Th-based fuels compatible with the current plants and operational features. This analysis focuses on a typical 4-loop PWR, with 17x17 fuel assembly design and TRUs (or Pu) admixed with Th (similar to U-MOX fuel, but with Th instead of U). Global calculations of the core were represented with unit assembly simulations using the Linear Reactivity Model (LRM). Several assembly configurations have been developed to offer two options that can be attractive during the TRU transmutation campaign: maximization of the TRU transmutation rate and capability for TRU multi-recycling, to extend the option of TRU recycling in LWR until the FR is available. Homogeneous as well as heterogeneous assembly configurations have been developed with various recycling schemes (Pu recycle, TRU recycle, TRU and in-bred U recycle etc.). Oxide as well as nitride fuels have been examined. This enabled an assessment of the potential for burning and multi-recycling TRU in a Th-based fuel PWR to compare against other more typical alternatives (U-MOX and variations thereof). Results will be shown indicating that Th-based PWR fuel is a promising option to multi-recycle and

  9. Sustained oxidative stress causes late acute renal failure via duplex regulation on p38 MAPK and Akt phosphorylation in severely burned rats.

    Full Text Available BACKGROUND: Clinical evidence indicates that late acute renal failure (ARF predicts high mortality in severely burned patients but the pathophysiology of late ARF remains undefined. This study was designed to test the hypothesis that sustained reactive oxygen species (ROS induced late ARF in a severely burned rat model and to investigate the signaling mechanisms involved. MATERIALS AND METHODS: Rats were exposed to 100°C bath for 15 s to induce severe burn injury (40% of total body surface area. Renal function, ROS generation, tubular necrosis and apoptosis, and phosphorylation of MAPK and Akt were measured during 72 hours after burn. RESULTS: Renal function as assessed by serum creatinine and blood urea nitrogen deteriorated significantly at 3 h after burn, alleviated at 6 h but worsened at 48 h and 72 h, indicating a late ARF was induced. Apoptotic cells and cleavage caspase-3 in the kidney went up slowly and turned into significant at 48 h and 72 h. Tubular cell ROS production shot up at 6 h and continuously rose during the 72-h experiment. Scavenging ROS with tempol markedly attenuated tubular apoptosis and renal dysfunction at 72 h after burn. Interestingly, renal p38 MAPK phosphorylation elevated in a time dependent manner whereas Akt phosphorylation increased during the first 24 h but decreased at 48 h after burn. The p38 MAPK specific inhibitor SB203580 alleviated whereas Akt inhibitor exacerbated burn-induced tubular apoptosis and renal dysfunction. Furthermore, tempol treatment exerted a duplex regulation through inhibiting p38 MAPK phosphorylation but further increasing Akt phosphorylation at 72 h postburn. CONCLUSIONS: These results demonstrate that sustained renal ROS overproduction induces continuous tubular cell apoptosis and thus a late ARF at 72 h after burn in severely burned rats, which may result from ROS-mediated activation of p38 MAPK but a late inhibition of Akt phosphorylation.

    The resuscitation of severe burn remains a controversial area within the burn care profession. There is ongoing debate as to what percentage burn is associated with a sufficient quality of life to support initial resuscitation efforts. We conducted a survey of delegates at the 39th Annual Meeting of the British Burns Association (2005), regarding attitudes towards resuscitation following major burns. Respondents were asked the maximum percentage total body surface area (TBSA) burn beyond which they would not wish to be resuscitated. They were also asked what maximum TBSA they perceived to be commensurate with an acceptable quality of life (QOL). One hundred and forty three of 300 delegates responded to the questionnaire. Thirty three percent of respondents would not wish to be resuscitated with 50-75% TBSA burns or greater. A further 35% would not wish to have life-sustaining intervention with 75-95% TBSA burns or greater. The remaining 32% indicated that they would not want resuscitation with TBSA burns>95%. Regardless of TBSA affected, 16% would not wish resuscitation if they had full thickness facial burns, a further 10% did not want resuscitation if both their hands and faces were affected. Our survey demonstrates the diversity of personal preference amongst burn care professionals. This would suggest that a unifying philosophy regarding the resuscitation of extensive burns will remain elusive.

With the establishment of modern burn treatment units and advances in acute care management contributed to a reduced mortality rate over the last decades. As a result of improved outcome, more attention has to be given to a comprehensive burn rehabilitation program. Burn rehabilitation is a process that starts from day of admission and continues for months or sometimes years after the initial event. The term ‘burn rehabilitation’ incorporates the physical, physiological and social aspects of care. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Burn rehabilitation aims to prevent the possible complications, minimalize joint contractures and deformities, increase range of motion, control hypertrophic scarring, achieve the best possible functional capacity and to regain the patients vocational and recreational activities.

  5. In-situ burning of Orimulsion : small scale burns

    International Nuclear Information System (INIS)

    This study examined the feasibility of burning Orimulsion. In-situ burning has always been a viable method for cleaning oil spills on water because it can effectively reduce the amount of spilled oil and eliminate the need to collect, store, transport and dispose of recovered oil. Orimulsion, however, behaves very differently from conventional oil when it is spilled because of its composition of 70 per cent bitumen in 30 per cent water. In-situ burning of this surfactant-stablized oil-in-water emulsion has never been seriously considered because of the perception that Orimulsion could not be ignited, and if it could, ignition would not be sustained. In this study, burn tests were conducted on 3 scales in a Cleveland Open Cup apparatus of 5 cm, 10 cm and 50 cm diameters. Larger scale burns were conducted in specially built pans. All tests were conducted on salt water which caused the bitumen to separate from the water. The objective was to determine if sufficient vapours could be generated to ignite the Orimulsion. The study also measured if a sustained flame would result in successful combustion. Both objectives were successfully accomplished. Diesel fuel was used to ignite the Orimulsion in the specially designed pan for large scale combustion. Quantitative removal of Orimulsion was achieved in all cases, but in some burns it was necessary to re-ignite the Orimulsion. It was noted that when Orimulsion burns, some trapped water droplets in the bitumen explode with enough force to extinguish a small flame. This did not occur on large-scale burns. It was concluded that the potential for successful in-situ burning increases with size. It was determined that approximately 1 mm in thickness of diesel fuel is needed to ignite a burn. 5 refs., 3 tabs., 4 figs

    Partial-thickness burn injury has the potential for reepithelialization and heals within 3weeks. If the wound is infected by bacteria before reepithelization, however, the depth of disruption increases and the lesion easily progresses to the full-thickness dermal layers. In the treatment of partial-thickness burn injury, it is important to prevent the wound area from bacterial infection with an antimicrobial dressing. Here, we have tested the antimicrobial properties of polymeric ultra-thin films composed of poly(lactic acid) (termed "PLA nanosheets"), which have high flexibility, adhesive strength and transparency, and silver sulfadiazine (AgSD), which exhibits antimicrobial efficacy. The AgSD-loaded nanosheet released Ag(+) for more than 3days, and exerted antimicrobial efficacy against methicillin-resistant Staphylococcus aureus (MRSA) in an in vitro Kirby-Bauer test. By contrast, a cell viability assay indicated that the dose of AgSD used in the PLA nanosheets did not show significant cytotoxicity toward fibroblasts. In vivo evaluation using a mouse model of infection in a partial-thickness burn wound demonstrated that the nanosheet significantly reduced the number of MRSA bacteria on the lesion (more than 10(5)-fold) and suppressed the inflammatory reaction, thereby preventing a protracted wound healing process.

    The authors review the etiology of U.K. military burns in light of increasing hybrid warfare. Analysis of the nature of these injured personnel will provide commanders with the evidence to plan for on-going and future operations. Case notes of all U.K. Armed Forces burn injured patients who were evacuated to the Royal Centre for Defence Medicine were reviewed. Demographics, burn severity, pattern, and mortality details were included. There were 134 U.K. military personnel with burns requiring return to the United Kingdom during 2001-2007. The median age was 27 (20-62) years. Overall, 60% of burns seen were "accidental." Burning waste, misuse or disrespect of fuel, and scalds were the most prevalent noncombat burns. Areas commonly burned were the face, legs, and hands. During 2006-2007 in the two major conflicts, more than 59% (n = 36) of the burned patients evacuated to the United Kingdom were injured during combat. Burns sustained in combat represent 5.8% of all combat casualties and were commonly associated with other injuries. Improvised explosive device, minestrike, and rocket-propelled grenade were common causes. The mean TBSA affected for both groups was 5% (1-70). The majority of combat burn injuries have been small in size. Greater provision of flame retardant equipment and clothing may reduce the extent and number of combat burns in the future. The numbers of noncombat burns are being reduced by good military discipline. PMID:21422938

  12. Calculation of the linear heat generation rates which violate the thermomechanical limit of plastic deformation of the fuel cladding in function of the burn up of a BWR fuel rod type

    International Nuclear Information System (INIS)

    The linear heat generation rates (LHGR) for a BWR type generic fuel rod, as function of the burnup that violate the thermomechanical limit of circumferential plastic deformation of the can (canning) in nominal operation in stationary state of the fuel rod are calculated. The evaluation of the LHGR in function of the burnt of the fuel, is carried out under the condition that the deformation values of the circumferential plastic deformation of the can exceeds in 0.1 the thermomechanical value operation limit of 1%. The results of the calculations are compared with the generation rates of linear operation heat in function of the burnt for this fuel rod type. The calculations are carried out with the FEMAXI-V and RODBURN codes. The results show that for exhibitions or burnt between 0 and 16,000 M Wd/tU a minimum margin of 160.8 W/cm exists among LHGR (439.6 W/cm) operation peak for the given fuel and maximum LHGR of the fuel (calculated) to reach 1.1% of circumferential plastic deformation of the can, for the peak factor of power of 1.40. For burnt of 20,000 MWd/tU and 60,000 MWd/tU exist a margin of 150.3 and 298.6 W/cm, respectively. (Author)

  13. In-situ burning of spilled oil

    International Nuclear Information System (INIS)

    Laboratory and field investigations have now demonstrated that the effective, sustained combustion of spilled oil on water requires that the oil being burned be at least 2-3 mm thick. This requires a properly manipulated fire containment boom to keep the spilled oil thick enough to support combustion. There are numerous situations where controlled in-situ burning of spilled oil can be carried out quickly, safely, and effectively. Some of the more significant burn experiences, the basics of controlled burning, and several different spill scenarios in which burning could be used as an effective response technique are presented. These scenarios include offshore exploration and production operations, marine pipeline accidents, tanker accidents, and spills into rivers and streams. Environmental constraints on in-situ burning are discussed. Nomograms are included which can be used to calculate the boom capacities and burn rates. 15 refs., 10 figs

    A new reduced size ITER-RC superconducting tokamak concept is proposed with the goals of studying burn physics either in an inductively driven standard tokamak (ST) mode of operation, or in a quasi-steady state advanced tokamak (AT) mode sustained by non-inductive means. This is achieved by reducing the radiation shield thickness protecting the superconducting magnet by 0.34 m relative to ITER and limiting the burn mode of operation to pulse lengths as allowed by the TF coil warming up to the current sharing temperature. High gain (Q≅10) burn physics studies in a reversed shear equilibrium, sustained by RF and NB current drive techniques, may be obtained. (author)

    CP violation in K and B decays is reviewed in the Standard Model (SM) and beyond the SM. In K decays, one is seeking first evidence for CP violation in direct $K\\to \\pi\\pi$ decays. This would not give a precise quantitative test for the present explanation of CP violation in terms of a phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Such tests are provided by a variety of CP asymmetries in neutral and charged B decays. Certain features, characterizing CP violation beyond the standard model, are outlined in the B meson system.

Postmortem burning of corpses is supposed to be one of the ways to hide a crime. Differentiating the actual cause of death in burn patients is therefore important. Medical examiners usually focus on the defining the changes that occur in tissues while forensic anthropologists deal with the changes related to the bone with or without any the influence of other tissues. Under the circumstances of fire, differentiating the perimortem trauma from that of postmortem cause of bone fractures is vital in determining the cause and motive of death

    Burn causes bone metabolic abnormality in most cases, including the changes in osteoblasts and osteoclasts, bone mass loss, and bone absorption, which results in decreased bone mineral density. These changes are sustainable for many years after burn and even cause growth retardation in burned children. The mechanisms of bone metabolic abnormality after burn include the increasing glucocorticoids due to stress response, a variety of cytokines and inflammatory medium due to inflammatory response, vitamin D deficiency, hypoparathyroidism, and bone loss due to long-term lying in bed. This article reviews the pathogenesis and regularity of bone metabolic abnormality after burn, the relationship between bone metabolic abnormality and burn area/depth, and the treatment of bone metabolic abnormality, etc. and discusses the research directions in the future.

    The fraction of fusion-reaction energy that is released in energetic charged ions, such as the alpha particles of the D-T reaction, can be thermalized within the reacting plasma and used to maintain its temperature. This mechanism facilitates the achievement of very high energy-multiplication factors Q, but also raises a number of new issues of confinement physics. To ensure satisfactory reaction operation, three areas of energetic-ion interaction need to be addressed: single-ion transport in imperfectly symmetric magnetic fields or turbulent background plasmas; energetic-ion-driven (or stabilized) collective phenomena; and fusion-heat-driven collective phenomena. The first of these topics is already being explored in a number of tokamak experiments, and the second will begin to be addressed in the D-T-burning phase of TFTR and JET. Exploration of the third topic calls for high-Q operation, which is a goal of proposed next-generation plasma-burning projects. Planning for future experiments must take into consideration the full range of plasma-physics and engineering R D areas that need to be addressed on the way to a fusion power demonstration.

The first part summarizes the human failures responsible for the Chernobyl disaster and argues that, in considering the human contribution to power plant emergencies, it is necessary to distinguish between: errors and violations; and active and latent failures. The second part presents empirical evidence, drawn from driver behavior, which suggest that errors and violations have different psychological origins. The concluding part outlines a resident pathogen view of accident causation, and seeks to identify the various system pathways along which errors and violations may be propagated

  4. Lorentz Violation and Gravity

    CERN Document Server

    Bailey, Quentin G

    2009-01-01

    In the last decade, a variety of high-precision experiments have searched for miniscule violations of Lorentz symmetry. These searches are largely motivated by the possibility of uncovering experimental signatures from a fundamental unified theory. Experimental results are reported in the framework called the Standard-Model Extension (SME), which describes general Lorentz violation for each particle species in terms of its coefficients for Lorentz violation. Recently, the role of gravitational experiments in probing the SME has been explored in the literature. In this talk, I will summarize theoretical and experimental aspects of these works. I will also discuss recent lunar laser ranging and atom interferometer experiments, which place stringent constraints on gravity coefficients for Lorentz violation.

    Recent results on CP-violation measurements in decays from energy asymmetric -factory experiments are reported. Thanks to large accumulated data samples, CP-violations in decays in mixing-decay interference and direct CP-violation are now firmly established. The measurements of three angles of the unitarity triangle from CP-violations of decays are quite consistent with the Standard Model expectations. These results strongly support the validity of the Kobayashi-Maskawa prescription of CP-violation.

    Full Text Available A significant burn injury is a serious and mortal event. The most important threat to life is hypovolemic shock with complex pathophysiologic mechanisms. Burn depth is classified as first, second, or third degree. Local inflammatory response results a vasodilatation and an increase in vascular permeability. A burn injury is a three dimensional ischemic wound. Zone of coagulation is the zone with maximum damage. Zone of stasis consists of damaged but viable tissues, the tissue is salvageable. In zone of hyperemia tissue perfusion is increased. At the beginning, cardiac output falls and systemic vascular resistance increases; cardiac performance improves as hypovolemia is corrected with fluid resuscitation. While cardiac output increases systemic vascular resistance falls below normal values and a hypermetabolic state develops. Pulmonary vascular resistance increases immediately after thermal injury and this is more prolonged. To avoid secondary pulmonary complications, the smallest resuscitation volume of fluids that maintains adequate tissue perfusion should be given. Changes parallel to the cardiovascular response develop in other organ systems. The reasons of burn injury can be thermal, electrical, chemical or radiation. It is important to know the exact mechanism of burn injury because of different therapies for a specific cause. In this review information about burn depth, local and systemic responses to burn injury and major causes of burn injury are presented.

  9. Lorentz violation naturalness revisited

    Belenchia, Alessio; Liberati, Stefano

    2016-01-01

    We revisit here the naturalness problem of Lorentz invariance violations on a simple toy model of a scalar field coupled to a fermion field via a Yukawa interaction. We first review some well-known results concerning the low-energy percolation of Lorentz violation from high energies, presenting some details of the analysis not explicitly discussed in the literature and discussing some previously unnoticed subtleties. We then show how a separation between the scale of validity of the effective field theory and that one of Lorentz invariance violations can hinder this low-energy percolation. While such protection mechanism was previously considered in the literature, we provide here a simple illustration of how it works and of its general features. Finally, we consider a case in which dissipation is present, showing that the dissipative behaviour does not percolate generically to lower mass dimension operators albeit dispersion does. Moreover, we show that a scale separation can protect from unsuppressed low-en...

    The aim of our study is to review our experience in the management of patients who sustained burns associated with suicidal attempts over a 10-year period. In particular, we look into the outcome and incidence of self-harm/suicide after discharge among the survivors. Thirty-one patients with median age 36 years, ranging from 10 to 74, were included. Twenty-three (74%) were males and eight (26%) were females. Nearly three quarters (74%) of our patients had a known history of psychiatric illness: 11 had known history of substance abuse; 3 of them had drug-induced psychosis; 6 had schizophrenia; 5 had depression; 4 had personality disorders; 1 had pathological gambling and another one had adjustment disorder. Relationship problems and work/financial difficulties were the commonest reason for the suicidal attempts. Self-inflicted flame burn was the most frequent (39%; 12 patients) method of burning. Six patients (19%) died. The remaining 25 patients healed and were discharged. Seventeen patients required ICU care. The median length of stay in ICU was 7 days. The overall median length of stay was 35 days. The median follow up time for those survived is 63 months. Only 4 of these patients had further suicidal/parasuicidal attempts. Despite the high mortality, once these patients survived the initial injury, they are unlikely to commit suicide again. Thus, we believe that aggressive resuscitation should therefore be advocated for all suicidal burn patients. PMID:22360959

  10. Moral Violations Reduce Oral Consumption.

    2014-07-01

    Consumers frequently encounter moral violations in everyday life. They watch movies and television shows about crime and deception, hear news reports of corporate fraud and tax evasion, and hear gossip about cheaters and thieves. How does exposure to moral violations influence consumption? Because moral violations arouse disgust and because disgust is an evolutionarily important signal of contamination that should provoke a multi-modal response, we hypothesize that moral violations affect a key behavioral response to disgust: reduced oral consumption. In three experiments, compared with those in control conditions, people drank less water and chocolate milk while (a) watching a film portraying the moral violations of incest, (b) writing about moral violations of cheating or theft, and (c) listening to a report about fraud and manipulation. These findings imply that "moral disgust" influences consumption in ways similar to core disgust, and thus provide evidence for the associations between moral violations, emotions, and consumer behavior.

    We present an overview of the construction of the general holographic dictionary for asymptotically locally Lifshitz and hyperscaling violating Lifshitz backgrounds with arbitrary dynamical exponents $z$ and $\\theta$, compatible with the null energy condition, which was recently developed in [1,2]. A concrete definition of asymptotically locally Lifshitz and hyperscaling violating Lifshitz backgrounds is provided in the context of a generic bottom-up Einstein-Proca-Dilaton theory, and a systematic procedure for solving the radial Hamilton-Jacobi equation via a covariant expansion in eigenfunctions of two commuting operators is presented. The resulting asymptotic solution of the Hamilton-Jacobi equation is subsequently used to derive the full holographic dictionary, including the Fefferman-Graham asymptotic expansions and the non-relativistic holographic Ward identities.

  12. Status in CP violation

    Twenty-five years after the discovery of CP violation in the neutral Kaon system, we still dont know exactly the origin and the components of that weak non invariance. The two more precise experiments give slightly different answers concerning the direct way of CP violation NA 31 gives ε prime/ε incompatible with the Superweak Model (for which ε prime=0) and in agreement with Standard Model predictions compatible with both. Again, one needs new and precise results in order to conclude about ε prime. E731 and NA31 are actually working on their new data samples. Longer term ideas are also being discussed, looking for new experiments able to give ε prime/ε with a precision. Concerning CPT invariance the situation seems to be more clear

    We study a class of nonstandard interactions of the newly discovered 125 GeV Higgs-like resonance that are especially interesting probes of new physics: flavor violating Higgs couplings to leptons and quarks. These interaction can arise in many frameworks of new physics at the electroweak scale such as two Higgs doublet models, extra dimensions, or models of compositeness. We derive constraints on flavor violating Higgs couplings using data on rare decays, electric and magnetic dipole moments, and meson oscillations. We find that flavor violating Higgs boson decays to leptons can be sizeable with, e.g., h -> tau mu and h -> tau e branching ratios of order 10% perfectly allowed by low energy constraints. We estimate the current LHC limits on h -> tau mu and h -> tau e decays by recasting existing searches for the SM Higgs in the tau-tau channel and find that these bounds are already stronger than those from rare tau decays. We also show that these limits can be improved significantly with dedicated searches an...

    This is a report of the first descriptive analytic study of a group of 183 burn patients, treated in the Burn Unit at the University Hospital of Cartagena, Colombia during the period since January 1985 until December 1990. There is presented experience with the selected group of 24 patients in whom the diagnosis of burn was associated with epilepsy.

    Perineal burns are not common in childhood but when they occur, they can produce severe complications. Conservative management by open wound care and topical agents is effective in most cases. However, in deep burns and when control of infection proves problematic, diverting colostomy may be necessary to control infection and achieve wound healing and graft take. Burns wound excision and skin grafting may be required in such cases. Contractures of various forms may develop and require plastic...

  18. Censorship of Chronological Violations

    CERN Document Server

    Monroe, H

    2006-01-01

    Rich non-arbitrary topological change may occur in a relativistic vacuum space-time that violates chronology at every point. However, each closed timelike curve (CTC) is typically "censored" by passing through a wormhole's event horizon, and a Cauchy-like surface may exist through which all timelike curves pass once and only once before crossing an event horizon. All CTCs in a time-orientable space-time must pass through a wormhole; otherwise the CTC could be deformed as a CTC to a non-time-orientable point. Therefore, if all wormholes have event horizons, there is chronology protection against uncensored CTCs, and the universe is safe for those historians who cannot see through event horizons. An indicator of a space-time's completeness which is conformally invariant, unlike geodesic or b-completeness, is that no causal boundary exists, which implies that the entire space-time is a chronology violating set. Such "causally complete" space-times fail to satisfy assumptions of the topological censorship theorem...

  19. Burns and military clothing.

    2001-02-01

    Burn injury is a ubiquitous threat in the military environment. The risks during combat are well recognised, but the handling of fuel, oil, munitions and other hot or flammable materials during peacetime deployment and training also imposes an inherent risk of accidental burn injury. Over the last hundred years, the burn threat in combat has ranged from nuclear weapons to small shoulder-launched missiles. Materials such as napalm and white phosphorus plainly present a risk of burn, but the threat extends to encompass personnel in vehicles attacked by anti-armour weapons, large missiles, fuel-air explosives and detonations/conflagrations on weapons platforms such as ships. Large numbers of burn casualties were caused at Pearl Harbor, in Hiroshima and Nagasaki, Vietnam, during the Arab/Israeli Wars and in the Falkland Islands conflict. The threat from burns is unlikely to diminish, indeed new developments in weapons seek to exploit the vulnerability of the serviceman and servicewoman to burns. Clothing can be a barrier to some types of burn--both inherently in the properties of the material, but also by trapping air between clothing layers. Conversely, ignition of the clothing may exacerbate a burn. There is hearsay that burnt clothing products within a wound may complicate the clinical management, or that materials that melt (thermoplastic materials) should not be worn if there is a burn threat. This paper explores the incidence of burn injury, the mechanisms of heat transfer to bare skin and skin covered by materials, and the published evidence for the complication of wound management by materials. Even light-weight combat clothing can offer significant protection to skin from short duration flash burns; the most vulnerable areas are the parts of the body not covered--face and hands. Multilayered combat clothing can offer significant protection for short periods from engulfment by flames; lightweight tropical wear with few layers offers little protection. Under

  20. T violation in neutralino decay

    International Nuclear Information System (INIS)

    We show that in the supersymmetric standard electroweak theory the neutralino decay causes CP violating phenomena. It will be possible to observe T odd asymmetry in the angular distribution if the trilepton decay of the W boson is found. We also discuss the constraint on the magnitude of CP violation by the electric dipole moment of the neutron. 10 refs., 9 figs. (Author)

  2. CPT violation: theory and phenomenology

    International Nuclear Information System (INIS)

    Invariance under the combined transformations of CPT (in any order) is guaranteed in Quantum Field Theory in flat space times due to a basic theorem (CPT theorem). The currently used formalism of particle physics phenomenology is based on this theorem. However, there may be violations of the basic underlying assumptions of this theorem in models of quantum gravity, namely Lorentz covariance, unitarity and/or locality of interactions. This may lead to observable (in principle) effects of CPT violation. Since there is no single figure of merit for this potential violation, the respective phenomenology is rather complex. In this review I classify the possible ways of CPT violation, and I describe briefly their phenomenology, in both terrestrial and astrophysical experiments, including antimatter factories, neutral mesons and neutrinos, and discuss the various sensitivities. I also pay attention to disentangling genuine quantum-gravity induced CPT violation from 'fake' violation due to ordinary matter effects. A particularly interesting situation arises when the breaking of CPT invariance is through unitarity violations, in the sense of the matter theory being viewed as an effective field theory, entangled with decoherening quantum gravity 'environments'. In such a case the quantum mechanical CPT operator is ill defined due to another mathematical theorem, and one has novel effects associated with CPT violating modifications of Einstein-Podolsky-Rosen type correlations of entangled meson states in B and φ meson factories.

    We define the CP transformation properties of scalars, fermions and vectors in a gauge theory and show that only three types of interactions can lead to CP violation: scalar interactions, fermion-scalar interactions and $ F \\tilde F $ associated with the strong CP problem and which involve only the gauge fields. For technicolor theories this implies the absence of CP violation within perturbation theory.

    Full Text Available Burning mouth syndrome (BMS is multifactorial in origin which is typically characterized by burning and painful sensation in an oral cavity demonstrating clinically normal mucosa. Although the cause of BMS is not known, a complex association of biological and psychological factors has been identified, suggesting the existence of a multifactorial etiology. As the symptom of oral burning is seen in various pathological conditions, it is essential for a clinician to be aware of how to differentiate between symptom of oral burning and BMS. An interdisciplinary and systematic approach is required for better patient management. The purpose of this study was to provide the practitioner with an understanding of the local, systemic, and psychosocial factors which may be responsible for oral burning associated with BMS, and review of treatment modalities, therefore providing a foundation for diagnosis and treatment of BMS.

    Burn is a common trauma in peace time and war. Burn care was not designated as a specific discipline but a subspecialty of general surgery in China until the 1950s. In 1958, along with the development of metallurgical industry in China, the number of burn patients was increased remarkably, followed by establishment of modern burn departments. A steel worker sustaining a burn injury with size of 89% total burn surface area (TBSA) and full-thickness wound size of 23% TBSA was successfully cured by burn experts of Shanghai Guangci Hospital (renamed Ruijin Hospital Affiliated to the School of Medicine of Shanghai Jiao Tong University). This was considered as a miracle in the history of burn treatment in the world. Thenceforth a number of burn patients with size over 80% TBSA were saved in Beijing, Shanghai, Chongqing, Xi'an, and other cities. However, with rapid advances in burn treatment, it was soon recognized that one should fully grasp the science of the underlying pathophysiological mechanism. To fulfill these demands, specialists devoted themselves to the study of basic problems, and they made significant and valuable contributions to the knowledge concerning basic problems in burn injury, followed by significant improvements in burn care. In the meantime, Chinese Burn Association and Chinese Journal of Burns were inaugurated. An overall strategy for treatment of severe burn patients with Chinese characteristics was established. However, it is also important to inherit traditional ideologies, namely"morality, diligence, excellence, and creativity". PMID:27426063

    International Nuclear Information System (INIS)

    The author discusses KNO scaling violations from ISR to collider energies, and related topics such as cluster size (are clusters produced at colliders just ordinary resonances ?), long-range correlations etc. the authors begin with a result on the energy dependence of heavy flavor production. The dual parton model (DPM) is based on the 1/N expansion, which is valid for any field theory with N degrees of freedom, and provides for a perturbative expansion in cases where the coupling constant is not small. It turns out that graphs with the simplest topology are dominant. Graphs with increasing topological complexity are suppressed by factors of 1/N/sup 2/. It has been shown that there is a one-to-one correspondence between the graphs in the 1/N expansion and those in a multiple-scattering model. This observations allow one to compute the weights σ/sub n/ of the different graphs in the 1/N expansion - essentially from unitarity

  9. Lepton family number violation

    Energy Technology Data Exchange (ETDEWEB)

    Herczeg, P.

    1999-03-01

    At present there is evidence from neutrino oscillation searches that the neutrinos are in fact massive particles and that they mix. If confirmed, this would imply that the conservation of LFN is not exact. Lepton family number violation (LFNV) has been searched for with impressive sensitivities in many processes involving charged leptons. The present experimental limits on some of them (those which the author shall consider here) are shown in Table 1. These stringent limits are not inconsistent with the neutrino oscillation results since, given the experimental bounds on the masses of the known neutrinos and the neutrino mass squared differences required by the oscillation results, the effects of LFNV from neutrino mixing would be too small to be seen elsewhere (see Section 2). The purpose of experiments searching for LFNV involving the charged leptons is to probe the existence of other sources of LFNV. Such sources are present in many extensions of the SM. In this lecture the author shall discuss some of the possibilities, focusing on processes that require muon beams. Other LFNV processes, such as the decays of the kaons and of the {tau}, provide complementary information. In the next Section he shall consider some sources of LFNV that do not require an extension of the gauge group of the SM (the added leptons or Higgs bosons may of course originate from models with extended gauge groups). In Section 3 he discusses LFNV in left-right symmetric models. In Section 4 he considers LFNV in supersymmetric models, first in R-parity conserving supersymmetric grand unified models, and then in the minimal supersymmetric standard model with R-parity violation. The last section is a brief summary of the author`s conclusions.

    More than three-quarters of deaths related to major burns are a consequence of infection, which is frequently ventilator associated pneumonia (VAP). A retrospective study was performed, over a five-year period, of ventilated children with major burns. 92 patients were included in the study; their mean age was 3.5 years and their mean total body surface area burn was 30%. 62% of the patients sustained flame burns, and 31% scalds. The mean ICU stay was 10.6 days (range 2-61 days) and the mean ventilation time was 8.4 days (range 2-45 days). There were 59 documented episodes of pneumonia in 52 patients with a rate of 30 infections per 1000 ventilator days. Length of ventilation and the presence of inhalational injury correlate with the incidence of VAP. 17.4% of the patients died (n=16); half of these deaths may be attributed directly to pneumonia. Streptococcus pneumonia, Pseudomonas aeruginosa, Acinetobacter baumanii and Staphylococcus aureus were the most prominent aetiological organisms. Broncho-alveolar lavage was found to be more specific and sensitive at identifying the organism than other methods. This study highlights the importance of implementing strictly enforced strategies for the prevention, detection and management of pneumonia in the presence of major burns. PMID:24468505

Patient was initially managed conservatively in general surgery ward and was referred to us after 3 days with necrosis of the burned skin and muscles over the shoulder and abdomen. Patient was initially managed conservatively and then thorough debridement of the necrotic skin over the left shoulder and upper arm was done and the area was split skin grafted. Patient developed enterocutaneous fistula, which healed over a period of 8 weeks. The granulating wound over the abdomen was also skin grafted and patient was discharged after 18 days. About 4 months, after the discharge patient presented with ventral hernia. Repair of ventral hernia by synthetic mesh application and reconstruction of the abdominal wall with a free tensor fascia lata flap was done over the mesh, but the flap failed. Then after debridement two random pattern transposition skin flaps, one from the right upper and another from the left lower abdomen were transposed over the abdominal wound and donor area was skin grafted. Patient was discharged after 17 days.

    International Nuclear Information System (INIS)

    The physics of CP violation is an area in which the Standard Model makes defininte predictions that have yet to be experimentally verified. B mesons are an excellent system in which to test these predictions. Current efforts to understand baryogenesis in the early universe suggest that there must be CP-violating processes betond the Standard Model. Reviewed here are the predictions of the Standard Model and how the various relationships between measurements can be used to test the Cabibbo-Kobayashi-Maskawa picture of CP-violation, to measure remaining unknown Standard Model parameters, and to glimpse physics beyond the Standard Model. 88 refs., 5 figs., 4 tabs

    Full Text Available Aim : To analyze the causes, demographic and socio-cultural aspects, and the magnitude of burn injuries prospectively and to evaluate the outcome of treatment of patients admitted to burns ICU of tertiary care hospital. Materials and Methods : A total of 892 burn patients admitted over a period of 6 years from January 2002 to December 2007 at tertiary care hospital in Punjab, India, were analyzed. Results : 54% patients were males. A majority of the patients, 704(79%, were in the age group of 15-45 years. Six hundred and thirty-four patients (72% sustained flame burns, while 17% and 7% sustained electrical and scald burns, respectively. A total of 470(53% patients sustained major two to three degree flame burns involving more than 45% of total body surface area (TBSA. The mortality rate was 40%, i.e. 357 patients died of burns and its related problems, in our study. Six hundred and thirty-nine patients (72% sustained burns in closed space of which 331 patients (52% sustained burns in kitchen. Seven hundred and seventy-nine patients sustained accidental burns. Burn victims were mainly Hindus and Sikhs. The mean hospital stay varied depending upon the percentage of burns. On an average, a patient with >45% TBSA burns received 15 whole blood transfusions. Split skin grafting was done in 416 patients. Most common complication encountered during their hospital stay was wound infection which was seen in 671 patients, followed by ARDS in 221 patients. The most common organisms causing wound infection were Pseudomonas and Acinetobacter. Conclusion : Developing country like India need an aggressive public education program so that people become more literate about various etiological factors causing burns and means of preventing them. Also needed are burn care hospitals which are easily accessible and affordable.

  1. Delineating a sustainable future

    International Nuclear Information System (INIS)

    The expression Develop Sustainable of wide use today in day is used among national political leaders and among environmentalists. The sustainable economy from the environmental point of view is that that obeys the basic principles or laws of the sustainability; principles so real as those of the aerodynamic one or those of the thermodynamic. If somebody intends, for example, to design an airplane, it will have to be adjusted to the aerodynamic principles and to print to the apparatus a certain stability degree so that it can fly. In the same way, an economic system environmentally sustainable it must respond to the balance principles if it doesn't want to be condemned to the failure. The fundamental laws or sustainability principles are as rigorous as the aerodynamic laws. The society can violate these laws in the short term; but not long term. As well as an airplane can lose height in a brief lapse without falling; the economy can violate the principles of the sustainability in the short term without collapsing. Among of the sustainability principles figure the following: long term; the extinction of species cannot exceed the evolution of the species; the soil erosion cannot exceed the soils formation; the destruction of forests cannot exceed the regeneration of the forests; the emissions of carbon cannot exceed the fixation of carbon; the fishing cannot exceed the regenerative capacity of the banks of fish and, in the human land, the morbidity cannot exceed the mortality.

The problems of CP violation in neutrino oscillations and of determining the nature - Dirac or Majorana - of massive neutrinos, are discussed. The seesaw mechanism of neutrino mass generation and the related leptogenesis scenario of generation of the baryon asymmetry of the Universe, are considered. The results showing that the CP violation necessary for the generation of the baryon asymmetry of the Universe in leptogenesis can be due exclusively to the Dirac and/or Majorana CP-violating phase(s) in the neutrino mixing matrix $U$, are briefly reviewed.

    Invariance under the combined transformations of CPT (in any order) is guaranteed in Quantum Field Theory in flat space times due to a basic theorem (CPT Theorem). The currently used formalism of particle physics phenomenology is based on this theorem. However, there may be violations of the basic underlying assumptions of this theorem in models of quantum gravity, namely Lorentz covariance, unitarity and/or locality of interactions. This may lead to observable (in principle) effects of CPT violation. Since there is no single figure of merit for this potential violation,the respective phenomenology is rather complex. In this review I classify the possible ways of CPT violation, and I describe briefly their phenomenology, in both terrestrial and astrophysical experiments, including antimatter factories, neutral mesons and neutrinos, and discuss the various sensitivities.

    We study an extension of the Standard Model (SM) in which two copies of the SM scalar $SU(2)$ doublet which do not acquire a Vacuum Expectation Value (VEV), and hence are \\textit{inert}, are added to the scalar sector. We allow for CP-violation in the \\textit{inert} sector, where the lightest \\textit{inert} state is protected from decaying to SM particles through the conservation of a $Z_2$ symmetry. The lightest neutral particle from the \\textit{inert} sector, which has a mixed CP-charge due to CP-violation, is hence a Dark Matter (DM) candidate. We discuss the new regions of DM relic density opened up by CP-violation, and compare our results to the CP-conserving limit and the Inert Doublet Model (IDM). We constrain the parameter space of the CP-violating model using recent results from the Large Hadron Collider (LHC) and DM direct and indirect detection experiments.

    The media have a profound influence on the actions of children and adults. Burns and burn prevention tend to be ignored or even mocked. The purpose of this presentation is to reveal the callousness of the media in its dealings with burns and burn prevention. Printed materials with a relationship to burns, risk of burning, or disrespect for the consequences of burns were collected. The materials were tabulated into four categories: comics, advertisements (ads), articles that made light of burns, and television shows that portrayed behavior that would risk burn injury. Most burn-related materials were found in comics or advertisements. Several comics made light of high-risk behavior with flames, scald injury, contact injury, or burns. In addition, several advertisements showed people on fire or actions that could easily lead to burns. Several articles and televisions shows portrayed high-risk behavior that, in some instances, led to copycat injuries. Flames are frequently used to sell items that target adolescent boys or young men. The high incidence injuries that frequent this population parallel the high-risk behaviors portrayed by the media. The media portrays flames and high-risk behavior for burn injury as being cool, funny, and without consequence. The use of flames on clothing and recreational equipment (skateboards, hot rods) particularly targets the high-risk adolescent male. The burn community should make the media aware of the harm it causes with its callous depiction and glorification of burns. PMID:12792237

    Supernovae provide a unique opportunity for large scale parity violation because they are dominated by neutrinos. We calculate the parity violating asymmetry A of neutrino emission in a strong magnetic field. We assume the neutrinos elastically scatter many times from slightly polarized neutrons. Because of multple interactions, A grows with the optical thickness of the proto-neutron star and may be much larger than previous estimates. As a result, the neutron star could recoil at a significant velocity.

    Full Text Available Accidental radioisotope burns are rare. The major components of radiation injury are burns, interstitial pneumonitis, acute bone marrow suppression, acute renal failure and adult respiratory distress syndrome. Radiation burns, though localized in distribution, have systemic effects, and can be extremely difficult to heal, even after multiple surgeries. In a 25 year old male who sustained such trauma by accidental industrial exposure to Iridium192 the early presentation involved recurrent haematemesis, pancytopenia and bone marrow suppression. After three weeks he developed burns in contact areas in the left hand, left side of the chest, abdomen and right inguinal region. All except the inguinal wound healed spontaneously but the former became a non-healing ulcer. Pancytopenia and bone marrow depression followed. He was treated with morphine and NSAIDs, epidural buprinorphine and bupivicaine for pain relief, steroids, antibiotics followed by wound excision and reconstruction with tensor fascia lata(TFL flap. Patient had breakdown of abdominal scar later and it was excised with 0.5 cm margins up to the underlying muscle and the wound was covered by a latissimis dorsi flap. Further scar break down and recurrent ulcers occurred at different sites including left wrist, left thumb and right heel in the next two years which needed multiple surgical interventions.

    Full Text Available Burn injuries and their subsequent treatment cause one of the most excruciating forms of pain imaginable. The psychological aspects of burn injury have been researched in different parts of the world, producing different outcomes. Studies have shown that greater levels of acute pain are associated with negative long-term psychological effects such as acute stress disorder, depression, suicidal ideation, and post-traumatic stress disorder for as long as 2 years after the initial burn injury. The concept of allostatic load is presented as a potential explanation for the relationship between acute pain and subsequent psychological outcomes. A biopsychosocial model is also presented as a means of obtaining better inpatient pain management and helping to mediate this relationship.

    Full Text Available Burning mouth syndrome (BMS is a complex disorder that is characterized by warm or burning sensation in the oral mucosa without changes on physical examination. It occurs more commonly in middle-aged and elderly women and often affects the tip of the tongue, lateral borders, lips, hard and soft palate. This condition is probably of multi-factorial origin, often idiopathic, and its etiopathogensis is unknown. BMS can be classified into two clinical forms namely primary and secondary BMS. As a result, a multidisciplinary approach is required for better control of the symptoms. In addition, psychotherapy and behavioral feedback may also help eliminate the BMS symptoms.

    Science.gov (United States)

    Faldmo, L; Kravitz, M

    1993-05-01

    Initial management of minor and moderate, uncomplicated burn injury focuses on wound management and patient comfort. Initial management of patients with major burn injury requires airway support, fluid resuscitation for burn shock, treatment for associated trauma and preexisting medical conditions, management of adynamic ileus, and initial wound treatment. Fluid resuscitation, based on assessment of the extent and depth of burn injury, requires administration of intravenous fluids using resuscitation formula guidelines for the initial 24 hours after injury. Inhalation injury complicates flame burns and increases morbidity and mortality. Electrical injury places patients at risk for cardiac arrest, metabolic acidosis, and myoglobinuria. Circumferential full-thickness burns to extremities compromise circulation and require escharotomy or fasciotomy. Circumferential torso burns compromise air exchange and cardiac return. Loss of skin function places patients at risk for hypothermia, fluid and electrolyte imbalances, and systemic sepsis. The first 24 hours after burn injury require aggressive medical management to assure survival and minimize complications. PMID:8489882

  18. Symmetry violations and rare decays

    International Nuclear Information System (INIS)

    This constitutes the report of the working group on symmetry violations and rare decays. The next generation of CP violating kaon decay experiments (the 2π and π0e+e- modes) were considered at the Tevatron and at the proposed Main Injector, effectively building upon the work of the earlier Fermilab Workshop on Physics at the Main Injector. The optimizations for the electromagnetic calorimeter and for background rejection are treated in some detail. Very precise CPT tests in the 2π decay modes are also treated. A sensitive experiment looking for flavor violation at the Main Injector (KL → μe) is discussed. The significant advantages of possible stretcher and prebooster rings are mentioned. 27 refs., 5 figs., 3 tabs

    In this work, we have studied the possibility of setting up Bell's inequality violating experiment in the context of cosmology, based on the basic principles of quantum mechanics. First we start with the physical motivation of implementing the Bell's inequality violation in the context of cosmology. Then to set up the cosmological Bell violating test experiment we introduce a model independent theoretical framework using which we have studied the creation of new massive particles by implementing the WKB approximation method for the scalar fluctuations in presence of additional time dependent mass contribution. Next using the background scalar fluctuation in presence of new time dependent mass contribution, we explicitly compute the expression for the one point and two point correlation functions. Furthermore, using the results for one point function we introduce a new theoretical cosmological parameter which can be expressed in terms of the other known inflationary observables and can also be treated as a fut...

    We explain the many reasons for the interest in flavor physics. We describe flavor physics and the related CP violation within the Standard Model, and explain how the B-factories proved that the Kobayashi-Maskawa mechanism dominates the CP violation that is observed in meson decays. We explain the implications of flavor physics for new physics, with emphasis on the “new physics flavor puzzle”, and present the idea of minimal flavor violation as a possible solution. We explain why the values flavor parameters of the Standard Model are puzzling, present the Froggatt-Nielsen mechanism as a possible solution, and describe how measurements of neutrino parameters are interpreted in the context of this puzzle. We show that the recently discovered Higgs-like boson may provide new opportunities for making progress on the various flavor puzzles.

    A 50-year-old man presented with a 2-day history of bilateral lower extremity cramping and dark urine. The patient was found to have a creatine phosphokinase (CPK) elevated of up to 2306 U/L, a serum uric acid of 9.7 mg/dL and 101 red blood cell's per high-powered field on urinalysis. On questioning, the patient endorsed daily exercise with free weights. There were no changes in his regular exercise and medication regimen, no muscle trauma, no recent drug use and no illness. The patient did mention using a new fat burner known as 'Fat Burn X', which he had begun taking 2 days prior to the onset of his muscle cramps. The patient was given normal saline intravenous fluid resuscitation for 48 h with resultant normalisation of his CPK and creatinine, and was discharged with primary care follow-up. PMID:26811412

    Chardin, G.

    1993-06-01

    Several arguments favour gravitation as the "Master Arrow of Time". Providing an explanation in terms of gravitation for the CP (and T) violation observed in the neutral kaon system, which provides the only example of a microscopic "arrow of time", is therefore extremely tempting. We show qualitatively that "antigravity" would provide just the amount of anomalous regeneration that we call CP violation and that a consequence of antigravity would be that any massive body would evaporate with the timescale of the Hawking radiation of black holes, which is linked to the generalized Second Law of Thermodynamics. Tests of this idea are proposed.

    Currently a large proportion of patients with severe burn injuries survive. This gives increasing challenges also for psychological recovery after the trauma. More than half of burn patients have mental disorders already before the burn injury but also patients who previously had no mental disorders may suffer from them. Some of the hospitalize burn patients have injuries due to suicidal attempts. Only a small proportion of burn patients receive appropriate psychiatric care although psychosocial interventions specifically planned for burn victims exist. More frequent screening of symtoms of mental disorders and psychiatric consultation, also after acute care in hospital, could lead to better management of post-burn psychiatric care as well as better management of the burn treatment and rehabilitation itself.

  18. Atomic CP-violating polarizability

    International Nuclear Information System (INIS)

    Searches for CP-violating effects in atoms and molecules provide important constrains on competing extensions to the standard model of elementary particles. In particular, CP violation in an atom leads to the CP-odd (T,P-odd) polarizability βCP: a magnetic moment μCP is induced by an electric field E0 applied to an atom, μCP=βCPE0. We estimate the CP-violating polarizability for rare-gas (diamagnetic) atoms He through Rn. We relate βCP to the permanent electric dipole moment (EDM) of the electron and to the scalar constant of the CP-odd electron-nucleus interaction. The analysis is carried out using the third-order perturbation theory and the Dirac-Hartree-Fock formalism. We find that, as a function of nuclear charge Z, βCP scales steeply as Z5R(Z), where slowly varying R(Z) is a relativistic enhancement factor. Finally, we evaluate the feasibility of setting a limit on electron EDM by measuring CP-violating magnetization of liquid Xe. We find that such an experiment could provide competitive bounds on electron EDM only if the present level of experimental sensitivity to ultraweak magnetic fields [Kominis et al., Nature 422, 596 (2003)] is improved by several orders of magnitude

    Allanach, B C; Sridhar, K

    2016-01-01

    We consider a modified Randall-Sundrum (RS) framework between the Planck scale and the GUT scale. In this scenario, RS works as a theory of flavour and not as a solution to the hierarchy problem. The latter is resolved by supersymmetrising the bulk, so that the minimal supersymmetric standard model being the effective 4-dimensional theory. Matter fields are localised in the bulk in order to fit fermion-mass and mixing-data. If $R$-parity violating terms are allowed in the superpotential, their orders of magnitude throughout flavour space are then predicted, resulting in rich flavour textures. If the $R$-parity violating contributions to neutrino masses are somewhat suppressed, then lepton-number violating models exist which explain the neutrino oscillation data while not being in contradiction with current experimental bounds. Another promising model is one where baryon number is violated and Dirac neutrino masses result solely from fermion localisation. We sketch the likely discovery signatures of the baryon...

    2012-02-01

    AIMS AND OBJECTIVES: The aim of this phenomenological study was to explore the emotions experienced by children\\'s nurses when caring for children with burns, in addition to ascertaining how the nurses dealt with these emotions. BACKGROUND: The nature of nursing practice is such that it inevitably generates some form of emotional response in nurses. The literature reveals that the manner nurses deal with their emotional experiences can impact on their nursing care. DESIGN: The study used Husserlian phenomenology to explore the emotional experiences of eight purposively selected children\\'s nurses who have worked on the burns unit of an Irish paediatric hospital. METHODS: Data were collected using in-depth, unstructured interviews and analysed using Colaizzi\\'s seven stage framework. RESULTS: The phenomenon of participants\\' emotional experiences is captured in four themes: (1) caring for children with burns, (2) supporting parents, (3) sustaining nurses\\' emotional well-being, and (4) learning to be a burns nurse. Nursing children with burns generated a myriad of emotions for participants. Burns dressing-changes, managing burn-related pain, supporting parents and the impact of busy workloads on the emotional care of children and their parents emerged as the most emotionally challenging aspects of participants\\' role. Participants recognised the need to manage their emotional responses and spoke of the benefits of a supportive nursing team. CONCLUSIONS: The findings offer insights into both the rewarding and challenging aspects of nursing children with burns. Nurses in this environment must be supported to recognise and manage their emotional responses to their work. RELEVANCE TO CLINICAL PRACTICE: Helping nurses to manage the emotional consequences of their work will help to sustain their emotional well-being, enhance the care received by children and also enable nurses to support parents in their role as partners in care.

  6. Is proportion burned severely related to daily area burned?

    International Nuclear Information System (INIS)

    The ecological effects of forest fires burning with high severity are long-lived and have the greatest impact on vegetation successional trajectories, as compared to low-to-moderate severity fires. The primary drivers of high severity fire are unclear, but it has been hypothesized that wind-driven, large fire-growth days play a significant role, particularly on large fires in forested ecosystems. Here, we examined the relative proportion of classified burn severity for individual daily areas burned that occurred during 42 large forest fires in central Idaho and western Montana from 2005 to 2007 and 2011. Using infrared perimeter data for wildfires with five or more consecutive days of mapped perimeters, we delineated 2697 individual daily areas burned from which we calculated the proportions of each of three burn severity classes (high, moderate, and low) using the differenced normalized burn ratio as mapped for large fires by the Monitoring Trends in Burn Severity project. We found that the proportion of high burn severity was weakly correlated (Kendall τ = 0.299) with size of daily area burned (DAB). Burn severity was highly variable, even for the largest (95th percentile) in DAB, suggesting that other variables than fire extent influence the ecological effects of fires. We suggest that these results do not support the prioritization of large runs during fire rehabilitation efforts, since the underlying assumption in this prioritization is a positive relationship between severity and area burned in a day.

    It is well known that the study of flavour physics and CP violation is very important to critically test the Standard Model and to look for possible signature of new physics beyond it. The observation of CP violation in kaon system in 1964 has ignited a lot of experimental and theoretical efforts to understand its origin and to look for CP violation effects in other systems besides the neutral kaons. The two -factories BABAR and BELLE, along with other experiments, in the last decade or so made studies in flavour physics and CP violation a very interesting one. In this article we discuss the status and prospectives of the flavour physics associated with the strange, charm and bottom sectors of the Standard Model. The important results in kaon sector will be briefly discussed. Recently, mixing in the charm system has been observed, which was being pursued for quite some time without any success. The smallness of the mixing parameters in the charm system is due to the hierarchical structure of the CKM matrix. Interestingly, so far we have not found CP violation in the charm system but in the future, with more dedicated experiments at charm threshold, the situation could change. Many interesting observations have been made in the case of bottom mesons and some of them show some kind of deviations from that of the Standard Model expectations which are mainly associated with the → flavour changing neutral current transitions. It is long believed that the system could be the harbinger of new physics since it is a system in which both bottom and strange quarks are the constituents. Recently, D0 and CDF announced their result for the mixing which is claimed to be the first possible new physics signature in the flavour sector. We plan to touch upon all important issues pointing out both theoretical and experimental developments and future prospects in this review article.

    The linear heat generation rates (LHGR) for a BWR type generic fuel rod, as function of the burnup that violate the thermomechanical limit of circumferential plastic deformation of the can (canning) in nominal operation in stationary state of the fuel rod are calculated. The evaluation of the LHGR in function of the burnt of the fuel, is carried out under the condition that the deformation values of the circumferential plastic deformation of the can exceeds in 0.1 the thermomechanical value operation limit of 1%. The results of the calculations are compared with the generation rates of linear operation heat in function of the burnt for this fuel rod type. The calculations are carried out with the FEMAXI-V and RODBURN codes. The results show that for exhibitions or burnt between 0 and 16,000 M Wd/tU a minimum margin of 160.8 W/cm exists among LHGR (439.6 W/cm) operation peak for the given fuel and maximum LHGR of the fuel (calculated) to reach 1.1% of circumferential plastic deformation of the can, for the peak factor of power of 1.40. For burnt of 20,000 MWd/tU and 60,000 MWd/tU exist a margin of 150.3 and 298.6 W/cm, respectively. (Author)

After undressing the infant, the mother discovered several lesions on the child’s abdomen and quickly sought medical attention. Given the unusual circumstances of the presentation, the child was hospitalized for both treatment and supervision. The beauty nail adhesive contained cyanoacrylate. In addition to its well-appreciated adhesive capacity, cyanoacrylate, in the presence of cotton or other tissues, is known to produce an exothermic reaction that may cause burns. Cyanoacrylate-based products, due to their possible adverse effects, should be kept away from children as advised. Odd injuries should always raise concerns about the possibility of inflicted injury.

    Chemical burns are less frequent in routine practice, but could be very serious owing to the complexity and severity of their actions. Influx of casualty after a civil disaster (industrial explosion) or military (war or terrorism) is possible. The action of these agents could be prolonged and deep. In addition to the skin, respiratory lesions and general intoxication could be observed. The urgent local treatment rely essentially on prolonged washing. Prevention and adequate emergency care could limit the serious consequences of these accidents. Accidents (thermal burns or electrisations) due to high or low voltage electricity are frequent. The severity is linked with the affected skin but especially with internal lesions, muscular, neurological or cardiac lesions. All cases of electrisation need hospital care. Locally, the lesions are often deep with difficult surgical repairs and often require amputation. Aesthetic and functional sequela are therefore frequent. Secondary complications could appear several months after the accident: cataract, dysesthesia and hypotonia. PMID:12621941

  16. Technology of straw burning

    International Nuclear Information System (INIS)

    The paper deals with the example of application of straw as fuel for a power plant with capacity of 1 MW, which is reconstructed from an old coal power plant. The article shows the advantages of straw as a source of energy, analyses the physical and chemical characteristics and temperature parameters, typical for straw. Moreover it indicates the specific circumstances of the straw burning processes. The paper focuses also on preparation and storing of straw for public use and in the energy sector. Comparing with fossil fuel, straw is a low-caloric natural source, whose energy value reached to 14-19 MJ/kg. This value depends partly on the kind of straw and its water or moisture content (MC). To the basic characteristics of energy aspects belong: - energy or heating value (HV) MJ/kg (in LPG it is MJ/ m3); - burning temperature; - melting point - temperature of ash; - weight kg/m3; - density; - Energy density MWh /m3; - Energy potential GJ/t; - Size-homogeneity of straw; - Water or Moisture Content (MC). The above mentioned characteristics have an influence on technical parameters of straw-burning boiler. These parameters define conditions process of straw preparation. (author)

  17. Wood would burn

    International Nuclear Information System (INIS)

    Absract: In view of the world-wide problem of energy sustainability and greenhouse gas production (carbon dioxide), it is timely to review the issues involved in generating heat and power from all fuels and especially new (to the UK) solid fuels, including high moisture fuels such as wood, SRF, oil shale, tar sands and brown coal, which will become major international fuels as oil and gas become depleted. The combustion properties of some of these materials are significantly different from traditional coal, oil and gas fuels, however the technology proposed herein is also applicable to these conventional fuels. This paper presents some innovative combustion system options and the associated technical factors that must be considered for their implementation. For clarity of understanding, the novel concepts will be largely presented in terms of a currently developing solid fuel market; biomass wood chips. One of the most important characteristics of many solid fuels to be used in the future (including oil shale and brown coal) is their high moisture content of up to 60%. This could be removed by utilising low grade waste heat that is widely available in industry to dry the fuel and thus reduce transport costs. Burning such dried wood for power generation also increases the energy available from combustion and thus acts as a thermal transformer by upgrading the low grade heat to heat available at combustion temperatures. The alternative approach presented here is to recover the latent heat by condensing the extrinsic moisture and the water formed during combustion. For atmospheric combustion, the temperature of the condensed combustion products is below the dew point at about 55-65 oC and is only suitable for recovery in an efficient district heating system. However, in order to generate power from the latent heat, the condensation temperature must be increased to the level where the heat can be used in the thermodynamic power cycle. This can be achieved by increasing

    2016-01-01

    We argue that lepton flavor violating (LFV) decays $M \\to \\ell_1 \\overline \\ell_2$ of quarkonium states $M$ with different quantum numbers could be used to put constraints on the Wilson coefficients of effective operators describing LFV interactions at low energy scales. We note that restricted kinematics of the two-body quarkonium decays allows us to select operators with particular quantum numbers, significantly reducing the reliance on the single operator dominance assumption that is prevalent in constraining parameters of the effective LFV Lagrangian. We shall also argue that studies of radiative lepton flavor violating $M \\to \\gamma \\ell_1 \\overline \\ell_2$ decays could provide important complementary access to those effective operators.

    After an introduction to the standard-model description of C P violation and a brief look at the present status of this phenomenon in the kaon system, a classification of non-leptonic B-decays is given and the formalism of B0d,s-B0d,s mixing is discussed. We then turn to the B-factory benchmark modes, C P violation in charged B decays, and the Bs-meson system. Finally, we focus both on B → πK decays, which play an important role to probe the CKM angle γ, and on the Bd → π+π-, Bs → K+K- system, which allows an interesting determination of β and γ. (orig.)

    Parity violation effects in a circular superconducting Josephson junction has been investigated in the eighties. That time it appeared that this phenomenon was not significant enough to be experimentally observable. In our work we show, that this rate can be increased in the case of a circular Josephson junction of an unconventional superconductor. Furthermore, this phenomenon can be more significant in the case of the ferromagnetic p-wave unconventional superconductor, since the effect is stronger for polarized pairs.

  1. CP violation with beautiful baryons

    Energy Technology Data Exchange (ETDEWEB)

    Dunietz, I. (European Organization for Nuclear Research, Geneva (Switzerland). Theory Div.)

    1992-10-01

    CP violation can be studied in modes of charmed or bottom baryons when a decay process is compared with its charge-conjugated partner. It can show up as a rate asymmetry and in a study of other decay parameters. Neither tagging nor time-dependences are required to observe CP violation with modes of baryons, in contrast to the conventional B{sup 0} modes. Numerous modes of bottom baryons have the potential to show large CP-violating effects within the Standard Model. Those effects can be substantial for modes with a D{sup 0}, which is seen in a final state that can also be fed from {anti D}{sup 0}. For instance, a comparison of the {Lambda}{sub b}{yields}{Lambda}D{sub CP}{sup 0} with the anti {Lambda}{sub b}{yields} anti {Lambda}D{sub CP}{sup 0} process can show sizeable CP violation. Here D{sub CP}{sup 0} denotes CP eigenstates of D{sup 0}, which occur at a few percent. Six related processes, such as {Lambda}{sub b}{yields}{Lambda}D{sup 0}, {Lambda}{sub b}{yields}{Lambda}{anti D}{sup 0}, {Lambda}{sub b}{yields}{Lambda}D{sub CP}{sup 0}, and their charge-conjugated counterparts, can extract {phi}, which is the most problematic angle of the unitarity triangle and which is conventionally probed with the B{sub s}{yields}{rho}{sup 0} K{sub S} asymmetry. Here D{sup 0} and anti D{sup 0} are identified by their charged kaon or lepton.

The CP-even phase of the propagator is exploited to study the CP-asymmetry in B+ --> tau+ + nu, which is neither experimentally searched for nor predicted by any other model. Furthermore we show that the novel CP-violation is consistent with the CPT theorem by identifying the CP-compensating mode in the unparticle sector.

  4. Parity violation in electron scattering

    International Nuclear Information System (INIS)

    The elaboration of the electroweak standard model from the discovery of parity violation to the weak neutral current is described in the first chapter. In the second chapter the author discusses the 2 experimental approaches of the parity violation experiments. In the first approach the weak neutral current can be assumed to be well known and can be used as a probe for the hadronic matter. The second approach consists in measuring the weak neutral current between 2 particles with known internal structure in order to test the predictions of the standard model in the low energy range. The chapters 3 and 4 are an illustration of the first approach through the HAPPEx series of experiments that took place in the Jefferson Laboratory from 1998 to 2005. The HAPPEx experiments aimed at measuring the contribution of strange quarks in the electromagnetic form factors of the nucleon through the violation of parity in the elastic scattering at forward angles. The last chapter is dedicated to the E158 experiment that was performed at the Slac (California) between 2000 and 2003. The weak neutral current was measured between 2 electrons and the high accuracy obtained allowed the physics beyond the standard model to be indirectly constraint up to a few TeV. (A.C.)

  5. CP violation and flavor mixing

    International Nuclear Information System (INIS)

    The development of the studies of CP violation and the quark and lepton flavors are reviewed based on the author's personal career. He started studying physics at Nagoya University before quark model came into the world. He entered the graduate program and the belonged to theoretical particle physics group led by Professor S. Sakata. In 1956, Sakata model was proposed on three baryons, n, p and lambda, which was eventually replaced by the quark model, but the root of the idea of the fundamental triplet was in Sakata model. Activities of Sakata group including proposal of Nagoya model, its further developments and the formulation of lepton flavor mixing are described based on his experience as a graduate student. After leaving Nagoya, he started to work on CP violation problem in Kyoto. The theoretical process they followed to explain CP violation and finally to propose the six-quark model in 1973 is described. Following their proposal, J/φ, τ-lepton, γ (bound state of quark b and anti-b) and quark t were discovered in '74, '75, '77 and '95', respectively. The large CP asymmetry in B-meson system expected from their theory was verified with electron positron collision experiments at B factories, KEKB of KEK and PEPII of SLAC. Measuring method and results of B factories are illustrated. Finally the lepton flavor mixing observed by K2K experiment with Super Kamiokande and reactor neutrinos with KamLAND, which are clearly showing the oscillating behavior, is described. (S. Funahashi)

    Severe burn injuries can require escharotomies which are urgent, infrequent, and relatively high-risk procedures necessary to preserve limb perfusion and sometimes ventilation. The American Burn Association Advanced Burn Life Support© course educates surgeons and emergency providers about escharotomy incisions but lacks a biomimetic trainer to demonstrate, practice, or provide assessment. The goal was to build an affordable biomimetic trainer with discrete points of failure and pilot a validation study. Fellowship-trained burn and plastic surgeons worked with special effect artists and anatomists to develop a biomimetic trainer with three discrete points of failure: median or ulnar nerve injury, fasciotomy, and failure to check distal pulse. Participants were divided between experienced and inexperienced, survey pre- and post-procedure on a biomimetic model while being timed. The trainer total cost per participant was less than $35. Eighteen participants were involved in the study. The inexperienced (0-1 prior escharotomies performed) had significantly more violations at the discrete points of failure relative to more experienced participants (P = .036). Face validity was assessed with 100% of participants agreement that the model appeared similar to real life and was valuable in their training. Given the advancements in biomimetic models and the need to train surgeons in how to perform infrequent, emergent surgical procedures, an escharotomy trainer is needed today. The authors developed an affordable model with a successful pilot study demonstrating discrimination between experienced and inexperienced surgeons. Additional research is needed to increase the reliability and assessment metrics. PMID:26594860

    Burns are responsible for significant mortality and morbidity worldwide and are among the most devastating of all injuries, with outcomes spanning the spectrum from physical impairments and disabilities to emotional and mental consequences. Management of burns and their sequelae even in well-equipped, modern burn units of advanced affluent societies remains demanding and extremely costly. Undoubtedly, in most low and middle income countries (LMICs) with limited resources and inaccessibility to sophisticated skills and technologies, the same standard of care is obviously not possible. Unfortunately, over 90% of fatal fire-related burns occur in developing or LMICs with South-East Asia alone accounting for over half of these fire-related deaths. If burn prevention is an essential part of any integrated burn management protocol anywhere, focusing on burn prevention in LMICs rather than treatment cannot be over-emphasized where it remains the major and probably the only available way of reducing the current state of morbidity and mortality. Like other injury mechanisms, the prevention of burns requires adequate knowledge of the epidemiological characteristics and associated risk factors, it is hence important to define clearly, the social, cultural and economic factors, which contribute to burn causation. While much has been accomplished in the areas of primary and secondary prevention of fires and burns in many developed or high-income countries (HICs) such as the United States due to sustained research on the epidemiology and risk factors, the same cannot be said for many LMICs. Many health authorities, agencies, corporations and even medical personnel in LMICs consider injury prevention to have a much lower priority than disease prevention for understandable reasons. Consequently, burns prevention programmes fail to receive the government funding that they deserve. Prevention programmes need to be executed with patience, persistence, and precision, targeting high

    An acoustic emission (AE) method is being used to measure the burning rate of solid propellant strands. This method has a precision of 0.5% and excellent burning rate correlation with both subscale and large rocket motors. The AE procedure burns the sample under water and measures the burning rate from the acoustic output. The acoustic signal provides a continuous readout during testing, which allows complete data analysis rather than the start-stop clockwires used by the conventional method. The AE method helps eliminate such problems as inhibiting the sample, pressure increase and temperature rise, during testing.

    More than 4 decades after the creation of the Brooke and Parkland formulas, burn practitioners still argue about which formula is the best. So it is no surprise that there is no consensus about how to resuscitate a thermally injured patient with a significant comorbidity such as heart failure or cirrhosis or how to resuscitate a patient after an electrical or inhalation injury or a patient whose resuscitation is complicated by renal failure. All of these scenarios share a common theme in that the standard rule book does not apply. All will require highly individualized resuscitations. PMID:27600129

    The inflammatory state after burn injury is characterized by an increase in capillary permeability that results in protein and fluid leakage into the interstitial space, increasing resuscitative requirements. Although the mechanisms underlying increased capillary permeability are complex, damage from reactive oxygen species plays a major role and has been successfully attenuated with antioxidant therapy in several disease processes. However, the utility of antioxidants in burn treatment remains unclear. Vitamin C is a promising antioxidant candidate that has been examined in burn resuscitation studies and shows efficacy in reducing the fluid requirements in the acute phase after burn injury.

    Kornhaber, Rachel Anne; Wilson, Anne

    2011-01-01

    The purpose of this qualitative study was to explore the concept of building resilience as a strategy for responding to adversity experienced by burns nurses. Nurses who care for patients with severe burn injury are often exposed to patients' pain and disfigurement, encountering emotional exhaustion, distress, reduced self-esteem, and desensitization to pain. Resilience has been identified as an essential characteristic for nurses in their work environment. Resilience assists nurses to bounce back and to cope in the face of adversity, sustaining them through difficult and challenging working environments. Nonetheless, there remains limited information that addresses the concept of building resilience in burns nurses. In 2009, seven burns nurses were recruited from a severe burn injury unit in New South Wales, Australia. A qualitative phenomenological methodology was used to construct themes depicting nurses' experiences. Participants were selected through purposeful sampling, and data were collected through in-depth individual semistructured interviews using open-ended questions. Data were analyzed with Colaizzi's phenomenological method of data analysis. The concept of building resilience as a strategy for coping with adversity was identified and organized into six categories: toughening up, natural selection, emotional toughness, coping with the challenges, regrouping and recharging, and emotional detachment. The findings clearly demonstrate that it is vital for burns nurses to build resilience to endure the emotional trauma of nursing patients with severe burn injury. Knowledge about building resilience could be incorporated into nursing education for both undergraduate and experienced nurses. Building resilience within the domain of burns nursing has the potential to retain nurses within the profession, having implications for staff development, orientation, and retention. PMID:21747335

In this paper, we present a theorem which provides necessary and sufficient conditions for the violation of the Heisenberg uncertainty principle. We illustrate our results with analytical examples.

    We show that the asymmetrical dynamical evolution of fields in the early Universe provides a new source for CP violation. This can lead to baryogenesis without any additional CP-violating interactions. The magnitude of this CP violation is time-dependent. In particular, it vanishes (or is very small) in the late Universe after the fields have relaxed (or are in their final approach) to their vacuum values. We provide an explicit example in which our mechanism is realized.

    2015-01-01

    A symmetry violation model is considered for a system that can spontaneously choose between identical states which differ from each other only in weak properties (R-L). Such mirror symmetry allows reproduction of observed qualitative properties of quark and lepton mixing matrices. The lepton mixing matrix evidences in this case in favor of the inverse mass spectrum and the Dirac nature of SM neutrino. Notwithstanding the Dirac properties of neutrino, an exchange of lepton numbers such as $e^{-}+\\mu^{+}\\rightarrow e^{+}+\\mu^{-}$ is possible but with only leptons participating in the process.

We allow for CP-violation in the \\textit{inert} sector, where the lightest \\textit{inert} state is protected from decaying to SM particles through the conservation of a $Z_2$ symmetry. The lightest neutral particle from the \\textit{inert} sector, which has a mixed CP-charge due...

  10. Higgs CP Violation from Vectorlike Quarks

    CERN Document Server

    Chen, Chien-Yi; Zhang, Yue

    2015-01-01

    We explore CP violating aspects in the Higgs sector of models where new vectorlike quarks carry Yukawa couplings mainly to the third generation quarks of the Standard Model. We point out that in the simplest model, Higgs CP violating interactions only exist in the hWW channel. At low energy, we find that rare B decays can place similarly strong constraints as those from electric dipole moments on the source of CP violation. These observations offer a new handle to discriminate from other Higgs CP violating scenarios such as scalar sector extensions of the Standard Model, and imply an interesting future interplay among limits from different experiments.

  11. CP Violation in the scalar sector

    CERN Document Server

    Emmanuel-Costa, D; Osland, P; Rebelo, M N

    2016-01-01

    Models with an extended scalar sector may in principle provide new sources of CP violation originating in the scalar potential. One of the simplest ways to implement this idea is to have CP violation in a two-Higgs-doublet model. Here, it leads to CP violation in trilinear weak gauge boson couplings. We discuss how these couplings are becoming constrained in the alignment limit. In a model with three Higgs doublets, subject to an $S_3$ symmetry, several complex vacua are possible. Some of these, but not all, may lead to spontaneous CP violation.

  12. CP violation in the B system

    International Nuclear Information System (INIS)

    This paper discusses some of the variety of CP violating processes in B decays and emphasize the advantages provided by decays into CP self-conjugate hadronic final states as a means of studying CP violation. New experimental inputs on the quark mixing matrix, which help narrow the range of predictions for hadronic CP violating asymmetries, are reviewed and some of the theoretical uncertainties connected with these predictions are discussed. Finally a brief discussion of present plans for experimentally observing CP violating effects in B decays is given

  13. Lorentz violation dispersion relation and its application

    Xiao, Zhi

    2008-01-01

    We derive modified dispersion relation (MDR) in the Lorentz violation extension of quantum electrodynamics (QED) sector in the standard model extension (SME) framework. Based on the extended Dirac equation and corresponding MDR, we observe the resemblance of the Lorentz violation coupling with spin-gravity coupling. We also develop a neutrino oscillation mechanism induced by the presence of nondiagonal terms of Lorentz violation couplings in 2-flavor space in a 2-spinor formalism by explicitly assuming neutrinos to be Marjorana fermions. We also obtain a much stringent bound ($\\backsim10^{-25}$) on one of the Lorentz violation parameters by applying MDR to the ultrahigh energy cosmic ray (UHECR) problem.

  14. Burning more than calories: treadmill friction injuries in children.

    LENUS (Irish Health Repository)

    Davidson, C C

    2012-02-01

    Treadmill injuries in young children are a serious but little documented problem. Friction burns occur when the hands come into contact with the moving belt resulting in deep burns that often require hospital admission and surgery. The aim of this study was to assess the nature and prevalence of injuries sustained and to highlight treadmill friction burns as a public health issue previously undocumented in Ireland. A retrospective chart review from January 2006 until March 2008 was performed and functional outcome was assessed by the modified Michigan Hand Outcomes Questionnaire. Eight girls and four boys from one year and seven months to seven years and five months were treated. Eight children required admission to hospital and to date three have required surgery for their injuries. This is a new and increasing problem in Ireland which must be highlighted.

  15. Fuel burning and climate

    International Nuclear Information System (INIS)

    Emission of soot particles and other air pollution indoors constitutes a considerable health hazard for a major part of the population in many developing countries, one of them being China. In these countries problems relating to poverty are the most important risk factors, undernourishment being the dominating reason. Number four on the list of the most serious health hazards is indoor air pollution caused by burning of coal and biomass in the households. Very high levels of soot particles occur indoors because of incomplete combustion in old-fashioned stoves and by use of low quality fuel such as sticks and twigs and straw and other waste from agriculture. This leads to an increase in a series of acute and chronic respiratory diseases, including lung cancer. It has been pointed out in recent years that emissions due to incomplete combustion of coal and biomass can contribute considerably to climate changes

  18. Lorentz violating kinematics: threshold theorems

    Science.gov (United States)

    Baccetti, Valentina; Tate, Kyle; Visser, Matt

    2012-03-01

    Recent tentative experimental indications, and the subsequent theoretical speculations, regarding possible violations of Lorentz invariance have attracted a vast amount of attention. An important technical issue that considerably complicates detailed calculations in any such scenario, is that once one violates Lorentz invariance the analysis of thresholds in both scattering and decay processes becomes extremely subtle, with many new and naively unexpected effects. In the current article we develop several extremely general threshold theorems that depend only on the existence of some energy momentum relation E(p), eschewing even assumptions of isotropy or monotonicity. We shall argue that there are physically interesting situations where such a level of generality is called for, and that existing (partial) results in the literature make unnecessary technical assumptions. Even in this most general of settings, we show that at threshold all final state particles move with the same 3-velocity, while initial state particles must have 3-velocities parallel/anti-parallel to the final state particles. In contrast the various 3-momenta can behave in a complicatedand counter-intuitive manner.

  19. Biological width: No violation zone

    2012-01-01

    Full Text Available Maintenance of gingival health is one of the keys for the longevity of teeth, as well as for the longevity of restorations. The concept of Biologic width has been widely described by periodontists and restorative dentists. An adequate understanding of relationship between periodontal tissues and restorative dentistry is paramount to ensure adequate form, function and esthetics, and comfort of the dentition. While most clinicians are aware of this important relationship, uncertainty remains regarding specific concepts such as biologic width and indications and applications of surgical crown lengthening. These violations lead to complications like gingival inflammation, alveolar bone loss and improper fit of the restorative component. This review gives the wide aspect of the complex question of biologic width and represents an attempt to answer some of the demands in relation to it. The article also discusses the possible methods to assess biologic width, problems that occur after improper margin placement in the periodontium and the alternative procedures for prevention of biological width violation.

  3. The effect of wind, ice and waves on the in-situ burning of emulsions and aged oils

    International Nuclear Information System (INIS)

    A series of small- and meso-scale in-situ burning tests was conducted on Spitsbergen to define the limitations and burn effectiveness of in-situ burning of water-in-oil emulsions in terms of water content, degree of evaporation, and film thickness; and to study how the presence of ice, waves, and wind affect in-situ burning. The tests were conducted in basins cut into the ice on a fjord. The size of the basins ranged from 4 to 300 m2. The largest basin was fitted with a wavemaker. Evaporated water-free oil was found to be easily ignited and to burn with high efficiency. The burn efficiency was not affected by waves. Highly evaporated oil with 25% water was hard to ignite with gelled gasoline. In the presence of waves, it was not possible to ignite a 12.5% stable water-in-oil emulsion. The presence of waves reduced the burn efficiency for emulsion with a low water content. The main problem with in-situ burning of emulsions is flame spreading; emulsions require a large initial burn area for the burn to be self-sustaining. Small ice floes and slush did not influence burn efficiency in a negative way. In-situ burning could not be accomplished in wind speeds above 10 m/s. 2 refs., 5 figs., 5 tabs

  4. Is light water reactor technology sustainable?

    International Nuclear Information System (INIS)

    This paper proposes criteria for determining ''intermediate sustainability'' over a 500-year horizon. We apply these criteria to Light Water Reactor (LWR) technology and the LWR industry. We conclude that LWR technology does not violate intermediate sustainability criteria for (1) environmental externalities, (2) worker and public health and safety, or (3) accidental radioactive release. However, it does not meet criteria to (1) efficiently use depleted uranium and (2) avoid uranium enrichment technologies that can lead to nuclear weapons proliferation. Finally, current and future global demand for LWR technology might be below the minimum needed to sustain the current global LWR industry. (author)

    Full Text Available Burn injury is one of the most serious injuries that mankind may face. In addition to serious inflammation, excessive fluid loss, presence of hemodynamic instability due to intercurrent factors such as debridements, infections and organ failure, very different levels and intensities of pain, psychological problems such as traumatic stress disorder, depression, delirium at different levels that occur in patient with severe burn are the factors which make it difficult to provide the patient comfort. In addition to a mild to moderate level of baseline permanent pain in burn patients, which is due to tissue damage, there is procedural pain as well, which occurs by treatments such as grafting and dressings, that are severe, short-term burst style 'breakthrough' pain. Movement and tactile stimuli are also seen in burn injury as an effect to sensitize the peripheral and central nervous system. Even though many burn centers have established protocols to struggle with the pain, studies show that pain relief still inadequate in burn patients. Therefore, the treatment of burn pain and the prevention of possible emergence of future psychiatric problems suc as post-traumatic stress disorder, the sedative and anxiolytic agents should be used as a recommendation according to the needs and hemodynamic status of individual patient.

    1991-01-01

    Charts of 108 consecutive adult patients with flame burns of 20% to 70% total body surface area were reviewed to determine the incidence of acute alcohol intoxication and the likelihood that intoxicated patients were chronic alcohol abusers, to assess morbidity and mortality in the alcoholic patient with burns, and to characterize the intervention used in postdischarge treatment of the alcoholic patient with burns who survives. Twenty-seven percent of patients were acutely intoxicated at the time of injury. Evidence for chronic alcohol abuse was apparent in 90% of intoxicated patients, compared to only 11% of nonintoxicated patients (p = 0.0001). Alcoholic patients with burns not only had an overall mortality rate three times that of nonalcoholics (p = 0.001) but also died of smaller burns (p less than 0.05). Surviving alcoholic patients with burns required significantly more intravenous antibiotics and a longer hospitalization. Social service evaluation of use of alcohol was made in 84% of the cases of surviving intoxicated burn victims. Further intervention was undertaken in two thirds of these cases, usually involving an outpatient treatment program. PMID:2050723

    Full Text Available Introduction Understanding of fluid shifts and recognition of the importance of early and appropriate fluid replacement therapy have significantly reduced mortality in the early post burn period. After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

    Full Text Available Rehabilitation is an essential and integral part of burn treatment. It is not something which takes place following healing of skin grafts or discharge from hospital; instead it is a process that starts from day one of admission and continues for months and sometimes years after the initial event. Burns rehabilitation is not something which is completed by one or two individuals but should be a team approach, incorporating the patient and when appropriate, their family. The term ′Burns Rehabilitation′ incorporates the physical, psychological and social aspects of care and it is common for burn patients to experience difficulties in one or all of these areas following a burn injury. Burns can leave a patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. The aims of burn rehabilitation are to minimise the adverse effects caused by the injury in terms of maintaining range of movement, minimising contracture development and impact of scarring, maximising functional ability, maximising psychological wellbeing, maximising social integration

  12. Novel Sensing Approach for Predicting SLA Violations

    2014-04-01

    Full Text Available Customer contentment plays a vital role in business environment. Service level agreements (SLA’s are signed between the service provider and the customer where SLA violation acts as a major constraint. SLA Violation is reduced through mechanisms involving Monitoring in case if any violations are probably to occur, predicting the violations in advance and applying necessary prevention mechanism that minimizes the total cost arising because of SLA violations. Service providers carry out adaptation measures in the case of violations. Adaptation is considered as an instant deed (i.e. for each Composition instance separately. Most of the existing technique involves adaptation mechanisms based on cost alone but allow customers to compromise on quality. Our proposed technique provides optimal adaptation measures based on both cost and quality. Cost optimization and quality enhancing technique are been used in the proposed work to carry out the task. In this methodology we predict the SLA violations in advance and also find out the paramount providers through customers feedback and apply ranking for the services using the highest score. To achieve the highest score the service provider should provide services with minimum cost and maximum efficiency and quality. Also the existing work does not include mechanisms to completely prevent SLA violations, which is been enhanced in the proposed work by accumulating NOP (No to One-time Profit technique.

    While the Kobayashi-Maskawa single phase origin of CP violation passed its first crucial precision test in $B→ J/ K_{S}$, the chirality of weak $b$-quark couplings has not yet been carefully tested. We discuss recent proposals for studying the chiral and CP-violating structures of these couplings in radiative and hadronic $B$ decays.

  14. Where is the origin of CP violations

    International Nuclear Information System (INIS)

    If experimentally b→c is more suppressed than b→u, the Kobayashi-Maskawa mechanism of CP violation may not work. In the SU(2)xU(1)xS3 model, which gives all elements of the KM matrix naturally by the quark masses, this is the case and CP violations originate mainly from the Yukawa sector. (Auth.)

    2016-06-01

    Intrusive images related to adverse experiences are an important feature of a number of psychological disorders and a hallmark symptom of posttraumatic stress disorder (PTSD). Depression, anxiety, and PTSD are all common reactions following a burn injury. However, the nature of burn-related trauma memories and associated intrusions and their contribution to psychological disorders is not well understood. The aim of the study was to take a broad look at the nature of imagery experienced by people who have sustained a burn injury. Nineteen participants completed self-report questionnaires assessing depression, anxiety, and PTSD symptoms and were administered a semi-structured interview which explored the characteristics (vividness, sensory modalities, intrusions, emotion intensity) of imagery formed in relation to their burn injuries. Ongoing intrusive imagery was reported by over half the participants and there were significant correlations between frequency of intrusive images and posttraumatic symptoms, and between intensity of emotions associated with intrusive images and depression and posttraumatic symptoms. A thematic analysis of the memory narratives revealed four main themes: threat to self, view of the world, view of others, and positive psychological change. These results are discussed in relation to existing trauma theory and burn injury literature. Implications for clinical practice and recommendations for further research are proposed. PMID:27005586

    2016-03-15

    We investigate the effect of the hyperscaling violation on the holographic superconductors. In the s-wave model, we find that the critical temperature decreases first and then increases as the hyperscaling violation increases, and the mass of the scalar field will not modify the value of the hyperscaling violation which gives the minimum critical temperature. We analytically confirm the numerical results by using the Sturm-Liouville method with the higher order trial function and improve the previous findings in Fan (J High Energy Phys 09:048, 2013). However, different from the s-wave case, we note that the critical temperature decreases with the increase of the hyperscaling violation in the p-wave model. In addition, we observe that the hyperscaling violation affects the conductivity of the holographic superconductors and changes the expected relation in the gap frequency in both s-wave and p-wave models.

  1. Nonlocality and gravity-induced CP violation

    CERN Document Server

    Ahluwalia, D V

    1998-01-01

    We consider a space-time dependent relative phase between the right- and left-handed spinors and show that it results in a violation of locality in the presence of gravity once the demand of parity covariance is dropped. This violation of locality is such that it readily interprets itself as a gravity-induced CP violation, and at the same time confirms an earlier remark by Wigner that a representation space carries more information than a wave equation. This happens, as Kirchbach has noted, because while the dimensionality of an irreducible representation space does not depend upon the concrete realization of the symmetry generators, Noether currents (Dirac, versus Majorana, versus the CP violating construct presented here) do. The gravity-induced CP violation provides a dynamical reason on how a neutron star carrying its baryon and lepton numbers can collapse into a black hole and loose information on the latter characteristics.

    CERN Document Server

    Kamand, Rasha; Schindler, Matthias R

    2016-01-01

    Any possible Lorentz violation in the hadron sector must be tied to Lorentz violation at the underlying quark level. The relationships between the theories at these two levels are studied using chiral perturbation theory. Starting from a two-flavor quark theory that includes dimension-four Lorentz-violation operators, the effective Lagrangians are derived for both pions and nucleons, with novel terms appearing in both sectors. Since the Lorentz violation coefficients for nucleons and pions are all related to a single set of underlying quark coefficients, it is possible to place approximate bounds on pion Lorentz violation using only proton and neutron observations. The resulting bounds on four pion parameters are at the $10^{-23}$ level, representing improvements of ten orders of magnitude.

    2015-08-01

    The present study examined whether perceivers' implicit theories about the fixedness of intelligence would modulate neurophysiological responses to stereotype-violating and stereotype-confirming information. Brain activity was recorded using EEG as participants read a series of stereotype-confirming or stereotype-violating behaviors performed by a target character. Compared to incremental theorists (who believe that intelligence is malleable), entity theorists (who believe that intelligence is fixed) displayed more pronounced N400 responses to stereotype-violating behaviors. In contrast, incremental theorists exhibited more pronounced N400 responses than entity theorists to stereotype-confirming behaviors. These results shed light on basic processes in Person Memory by suggesting that perceivers make a distinction at the neurocognitive level between stereotype violations versus implicit theory violations.

  4. CP violation in K and B decays

    International Nuclear Information System (INIS)

    The author reviews basic aspects of the phenomenology of CP violation in the decays of K and B mesons. In particular he discusses the commonly used classification of CP violation--CP violation in the mass matrix, in the interference of mixing with decay, and in the decay amplitude itself--and the related notions of direct and indirect CP violation. These concepts are illustrated with explicit examples. The author also emphasizes the highlights of this field including the clean observables B(KL → π0ν anti ν) and ACP (B → J/ΨKS). The latter quantity serves to demonstrate the general features of large, mixing induced CP violation in B decays

    The phenomenology of 3-neutrino mixing, the current status of our knowledge about the 3-neutrino mixing parameters, including the absolute neutrino mass scale, and of the Dirac and Majorana CP violation in the lepton sector are reviewed. The problems of CP violation in neutrino oscillations and of determining the nature - Dirac or Majorana - of massive neutrinos are discussed. The seesaw mechanism of neutrino mass generation and the related leptogenesis scenario of generation of the baryon asymmetry of the Universe are considered. The results showing that the CP violation necessary for the generation of the baryon asymmetry of the Universe in leptogenesis can be due exclusively to the Dirac and/or Majorana CP-violating phase(s) in the neutrino mixing matrix U are briefly reviewed. The discrete symmetry approach to understanding the observed pattern of neutrino mixing and the related predictions for the leptonic Dirac CP violation are also reviewed.

    Fluid resuscitation of burn patients is commonly initiated using modified Brooke or Parkland formula. The fluid infusion rate is titrated up or down hourly to maintain adequate urine output and other endpoints. Over-resuscitation leads to morbid complications. Adherence to paper-based protocols, flow sheets, and clinical practice guidelines is associated with decreased fluid resuscitation volumes and complications. Computerized tools assist providers. Although completely autonomous closed-loop control of resuscitation has been demonstrated in animal models of burn shock, the major advantages of open-loop and decision-support systems are identifying trends, enhancing situational awareness, and encouraging burn team communication.

    2007-01-01

    We show that any Lorentz violating theory with two or more propagation speeds is in conflict with the generalized second law of black hole thermodynamics. We do this by identifying a classical energy-extraction method, analogous to the Penrose process, which would decrease the black hole entropy. Although the usual definitions of black hole entropy are ambiguous in this context, we require only very mild assumptions about its dependence on the mass. This extends the result found by Dubovsky and Sibiryakov, which uses the Hawking effect and applies only if the fields with different propagation speeds interact just through gravity. We also point out instabilities that could interfere with their black hole {\\it perpetuum mobile}, but argue that these can be neglected if the black hole mass is sufficiently large.

  8. Parity violation and electron scattering

    International Nuclear Information System (INIS)

    I have been asked to set stage for the more specialized talks to follow and to review the history of parity nonconservation in electron scattering. In electron scattering, parity violation (PV) is the unique signal which allows us to study the weak interactions among the much stronger electromagnetic ones. It is observed through the detection of a pseudoscalar quantity in the cross section or rate of a reaction. These pseudoscalars usually involve a spin or polarization. Since it is known that spin effects are more sensitive to dynamics than differential or total cross sections, which are partially determined by geometry, PV measurements allow us to learn about the weak interactions and nucleon and nuclear structure. Because the weak interactions are of short range, the measurements are sensitive to different aspects of the target structure than the long range electromagnetic scattering. 15 refs., 7 figs

  9. An Analysis of Shuttle Crew Scheduling Violations

    2012-01-01

    From the early years of the Space Shuttle program, National Aeronautics and Space Administration (NASA) Shuttle crews have had a timeline of activities to guide them through their time on-orbit. Planners used scheduling constraints to build timelines that ensured the health and safety of the crews. If a constraint could not be met it resulted in a violation. Other agencies of the federal government also have scheduling constraints to ensure the safety of personnel and the public. This project examined the history of Space Shuttle scheduling constraints, constraints from Federal agencies and branches of the military and how these constraints may be used as a guide for future NASA and private spacecraft. This was conducted by reviewing rules and violations with regard to human aerospace scheduling constraints, environmental, political, social and technological factors, operating environment and relevant human factors. This study includes a statistical analysis of Shuttle Extra Vehicular Activity (EVA) related violations to determine if these were a significant producer of constraint violations. It was hypothesized that the number of SCSC violations caused by EVA activities were a significant contributor to the total number of violations for Shuttle/ISS missions. Data was taken from NASA data archives at the Johnson Space Center from Space Shuttle/ISS missions prior to the STS-107 accident. The results of the analysis rejected the null hypothesis and found that EVA violations were a significant contributor to the total number of violations. This analysis could help NASA and commercial space companies understand the main source of constraint violations and allow them to create constraint rules that ensure the safe operation of future human private and exploration missions. Additional studies could be performed to evaluate other variables that could have influenced the scheduling violations that were analyzed.

  10. Propranolol Improves Impaired Hepatic Phosphatidylinositol 3-Kinase/Akt Signaling after Burn Injury

    Severe burn injury is associated with induction of the hepatic endoplasmic reticulum (ER) stress response. ER stress leads to activation of c-Jun N-terminal kinase (JNK), suppression of insulin receptor signaling via phosphorylation of insulin receptor substrate 1 and subsequent insulin resistance. Marked and sustained increases in catecholamines are prominent after a burn. Here, we show that administration of propranolol, a nonselective β1/2 adrenergic receptor antagonist, attenuates ER stre...

    Full Text Available Domestic burns in neonate are rare in literature. Neonates are high risk for burns because of their thin and fragile skin, fluid overload or dehydration as the fluid balance range is small and immature immune system leading to septicaemia. Neonates are not small adults, owing to their different physiological response makes the management of neonates challenging as the clinical signs are different from the adults and the resuscitation protocols or end points are also different. We present a case of 11 days old neonate, who sustained 51% scald burns when the hot water bag being used by her mother accidentally burst, the youngest reported case of domestic scald burns with such high percentage. The baby was managed by fluid resuscitation, antibiotics, dressings, ventilatory support for septicaemia and subsequently homograft application. The neonate was discharged with completely healed areas after 35 days of burns and is on regular follow up and no complications have been observed.

  17. Burns, hypertrophic scar and galactorrhea

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available An 18-year old woman was admitted to Motahari Burn Center suffering from 30% burns. Treatment modalities were carried out for the patient and she was discharged after 20 days. Three to four months later she developed hypertrophic scar on her chest and upper limbs .At the same time she developed galactorrhea in both breasts and had a disturbed menstrual cycle four months post-burn. On investigation, we found hyperprolactinemia and no other reasons for the high level of prolactin were detected. She received treatment for both the hypertrophic scar and the severe itching she was experiencing. After seven months, her prolactin level had decreased but had not returned to the normal level. It seems that refractory hypertrophic scar is related to the high level of prolactin in burns patients.

  2. CP violation in charged B decays

    International Nuclear Information System (INIS)

    CP violation in decay rates of, say, Bo → ψKs, important as they are, are primarily due to CP violation in the Bo bar Bo mass matrix. It is important to isolate CP violation that occurs in the decay process itself, since it provides independent checks on the mechanism of CP violation in nature. To this end, partial rate differences between B+ and B- would be particularly useful, since no mixing effects can occur, while complications such as effects of CP eigenstates in the final state would be absent as well. It is remarkable that CP violation can still arise, through interference effects between two amplitudes that have different CP-violating phases, as well as different final state interaction (FSI) phase shifts. In this paper, the author concentrates on the so-called penguin diagrams. Penguin diagrams provide both the ingredients for partial rate asymmetries. Being a loop diagram, it involves all three generations, each generation contributing with different KM elements. AT the same time, loop effects that involve real (on-shell) particle rescattering provide the necessary absorptive part (FSI phase). In what follows, the author reviews the subject of penguin-induced CP violation, with some emphasis on recent developments. Both inclusive and exclusive B± decays are discussed

The system studied is a Maxwell-Chern-Simons-Higgs system in the broken phase, for which the parity-violating terms are well known at zero temperature. At nonzero temperature the static and long-wavelength limits of the parity violating terms have very different structure, and involve non-analytic log terms depending on the various mass scales. At high temper...

  5. Dynamical CP violation in the early Universe

    International Nuclear Information System (INIS)

    Following earlier ideas of Dolgov, we show that the asymmetrical dynamical evolution of fields in the early Universe provides a new source for CP violation. This can lead to baryogenesis without any additional CP-violating interactions. The magnitude of this CP violation is time-dependent. In particular, it vanishes (or is very small) in the late Universe after the fields have relaxed (or are in their final approach) to their vacuum values. We provide an explicit example in which our mechanism is realized

    1999-01-01

    We consider nuclei produced in core collapse supernovae and subjected to a high neutron flux. We show that an accelerator mass spectrometry experiment that searched for traces of anomalous iron isotopes could set limits on the order of $10^{-20}-10^{-25}$ on (or perhaps discover) Pauli principle violation by neutrons. A similar search for anomalous Co isotopes could set limits in the range $10^{-13}-10^{-18}$ on Pauli principle violation by protons. We show that existing data on Oxygen can be used to set a limit of about $10^{-17}$ in one proposed model of such violation.

  7. Violating a Bell inequality with classical states

    Liu, Qin; Lamas-Linares, Antía; Skaar, Johannes; Makarov, Vadim; Kurtsiefer, Christian

    2011-01-01

    A strong probe for limits of classical physics is the Bell inequality between measurements of separated particles. Its violation can be used to secure a shared secret between two parties, but a fair-sampling assumption has to be made for limited detection efficiencies. Here, we present an experimental violation of a Bell inequality by classical states, exploiting imperfections in common photodetectors. We also propose measurements to obtain violations exceeding those allowed by quantum physics for ideal Bell tests. This exploit demonstrates that device-independent quantum cryptography requires the detection loophole be closed.

  8. Definitions of minimal flavour violation for leptons

    International Nuclear Information System (INIS)

    Neutrino masses imply the violation of lepton flavour and new physics beyond the Standard Model. However, flavour change has only been observed in oscillations. In analogy with the quark sector, we could deduce the existence of a principle of Minimal Flavour Violation also for Leptons (MFVL). Such an extension is not straightforward, since the mechanisms generating neutrino masses are unknown and many scenarios can be envisaged. Thus, we explore some possible definitions of MFVL and propose a notion that can include many models. We show, furthermore, that flavour violating processes are not necessarily controlled by the PMNS mixing matrix. (author)

  14. Sustainable cities

    International Nuclear Information System (INIS)

    The Sustainable City Project, a collaboration among the cities of Portland, Oregon, and San Francisco and San Jose, California, aims at developing and implementing sustainable energy planning methods and programs for cites. For a period of two years (1989-90), the three project cities worked in parallel, yet pursued independent courses to develop appropriate sustainable urban energy practices to meet local needs and aspirations. Central to the Sustainable City Project was finding ways to manage today's urban energy needs without jeopardizing the needs of future generations. Sustainability implies that nothing should go to waste, but rather should contribute to the proper balance between the natural environment and the built environment Sustainable urban energy systems encompass more than energy efficiency and energy conservation measures: they must be diverse, flexible, self-reliant, renewable, and integrated. Since local governments make decisions affecting land use, building codes, transportation systems, waste disposal, and power plants--all of which impact energy resource use--local jurisdictions can do much to ensure their own sustainable future. This paper will present an accounting of the specific steps that each city took to determine and begin implementation of their respective approaches to sustainable energy planning, with a specific focus on the City of San Jose activities. Useful tools for facilitating community process, program planning and implementation, and quantitative analysis will also be discussed

  15. Lorentz violations in multifractal spacetimes

    CERN Document Server

    Calcagni, Gianluca

    2016-01-01

    Using the recent observation of gravitational waves (GW) produced by a black-hole merger, we place a lower bound on the energy above which a multifractal spacetime would manifest an anomalous geometry and, in particular, violations of Lorentz invariance. In the so-called multifractional theory with $q$-derivatives, we show that the deformation of dispersion relations is much stronger than in generic quantum-gravity approaches (including loop quantum gravity) and, contrary to the latter, present observations on GWs can place very strong bounds on the characteristic scales at which spacetime deviates from standard Minkowski. The energy at which multifractal effects should become apparent is $E_*>10^{14}\\,\\text{GeV}$ (thus improving previous bounds by 12 orders of magnitude) when the exponents in the measure are fixed to their central value $1/2$. We also estimate, for the first time, the effect of logarithmic oscillations in the measure (corresponding to a discrete spacetime structure) and find that they do not...

  17. Chronology violation and the Cosmological Argument

    CERN Document Server

    Romero, G E

    2003-01-01

    The Kalam Cosmological Argument is perhaps the most solid and widly discussed argument for a caused creation of the universe. The usual objections to the argument mainly focus on the second premise. In this paper we discuss the dependency of the first premise on the topological structure of the space-time manifold adopted for the underlying cosmological model. It is shown that in chronology-violating space-times the first premise is also violated. The chronology-violation, in turn, requires a massive violation of the so-called energy conditions which could have observational effects that are briefly discussed here. Hence, astronomical observations could be relevant for the validity of the metaphysical argument. In this sense, it is possible to talk of "observational theology".

    Kurth, Thorsten; Rinaldi, Enrico; Vranas, Pavlos; Nicholson, Amy; Strother, Mark; Walker-Loud, Andre

    2015-01-01

    The electroweak interaction at the level of quarks and gluons are well understood from precision measurements in high energy collider experiments. Relating these fundamental parameters to Hadronic Parity Violation in nuclei however remains an outstanding theoretical challenge. One of the most interesting observables in this respect is the parity violating hadronic neutral current: it is hard to measure in collider experiments and is thus the least constrained observable of the Standard Model. Precision measurements of parity violating transitions in nuclei can help to improve these constraints. In these systems however, the weak interaction is masked by effects of the seven orders of magnitude stronger non-perturbative strong interaction. Therefore, in order to relate experimental measurements of the parity violating pion-nucleon couplings to the fundamental Lagrangian of the SM, these non-perturbative effects have to be well understood. In this paper, we are going to present a Lattice QCD approach for comput...

  2. Revisiting holographic superconductors with hyperscaling violation

    CERN Document Server

    Pan, Qiyuan

    2015-01-01

    We reinvestigate the effect of the hyperscaling violation on the holographic superconductors reported recently in J. High Energy Phys. {\\bf 09}, 048 (2013) [arXiv:1305.2000]. Different from the previous findings, we find that the increase of the hyperscaling violation makes it harder first and then easier for the scalar operator to condense, and the mass of the scalar field will not modify the value of the hyperscaling violation which gives the minimum critical temperature. In particular, we improve the Sturm-Liouville method by including the higher order terms in the expansion of the trial function to obtain the analytical results which are completely consistent with the numerical computations. Moreover, we observe that the hyperscaling violation affects the conductivity of the holographic superconductors and changes the expected relation in the gap frequency.

    Chiang, Cheng-Wei; Senaha, Eibun

    2016-01-01

    We investigate feasibility of electroweak baryogenesis with lepton flavor violation in a two-Higgs doublet model. By scrutinizing heavy Higgs boson mass spectra, regions satisfying both strong first-order electroweak phase transition and the muon $g-2$ anomaly are identified. We also estimate the baryon number density by exploiting extra Yukawa couplings in the $\\mu$-$\\tau$ sector. It is found that a CP-violating source term can be enhanced by the $\\mu$-$\\tau$ flavor-violating coupling together with the extra $\\tau$ coupling. With $\\mathcal{O}(1)$ Yukawa couplings and CP-violating phases, the observed baryon number density is marginally produced under a generous assumption on a bubble wall profile.

    We analyze the flavor violation in warped extra dimension due to radion mediation. We show that \\Delta S=2 and \\Delta B=2 flavor violating processes impose stringent constraints on radion mass, m_\\phi and the scale \\Lambda_\\phi. In particular, for \\Lambda_\\phi ~ O(1) TeV, B_d^0-\\bar{B}^0_d implies that m_\\phi ~ 25 GeV. We also study radion contributions to lepton flavor violating processes: \\tau -> (e,\\mu) \\phi, \\tau -> e\\mu^+\\mu^- and B -> l_i l_j. We show that BR(B_s -> \\mu^+ \\mu^-) can be of order 10^{-8}, which is reachable at the LHCb. The radion search at LHC, through the flavor violation decays into \\tau \\mu or top-charm quarks, is also considered.

    Latest LHCb measurements of $CP$ violation in b-hadrons are presented based on $pp$ collision data collected in 2011 and 2012 at centre-of-mass energies of $\\sqrt{s}=7$ $\\rm TeV$ and $8\\ \\rm TeV$ respectively. The total integrated luminosity collected is 3.0 fb$^{-1}$. Results include recent measurements of $CP$ violation in $B_d$ and $B_s$ mixing, along with those of quantifying the effects of $b\\to c\\bar{c} s$ loop pollution. Standard Model $CP$ violation tests in loop transitions are discussed with results consistent with expectations.

    Violations of CPT invariance can induce neutrino-to-antineutrino transitions. We study this effect for solar neutrinos and use the upper bound on the solar neutrino-to-antineutrino transition probability from the KamLAND experiment to constrain CPT-symmetry-violating coefficients of the general Standard-Model Extension. The long propagation distance from the Sun to the Earth allows us to improve existing limits by factors ranging from about a thousand to $10^{11}$.

    In this work we study the issue of gauge anomalies in Lorentz-violating QED. To do so, we opt to use the BRST formalism within of the algebraic renormalization approach, reducing our study to a cohomology problem. Since that this approach is independent of the renormalization scheme, the results here obtained are expected to be general. We find that the Lorentz-violating QED is free of gauge anomalies to all orders in perturbation theory.

We work in the three neutrino flavor framework.

    The motivation most often cited in searches for D0-anti-D0 mixing and CP-violation in charm system lies with the possibility of observing a signal from new physics which dominates that from the Standard Model. We review recent theoretical predictions and experimental constraints on D0-anti-D0 mixing parameters. We also discuss the current status of searches for CP-violation in charmed meson transitions, as well as some recent theoretical ideas.

  12. Exploring CP violation in the MSSM

    International Nuclear Information System (INIS)

    We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximise CP-violating observables subject to the experimental upper bounds on electric dipole moments. We also implement CP-conserving constraints from Higgs physics, flavour physics and the upper limits on the cosmological dark matter density and spin-independent scattering. We study possible values of observables within the constrained MSSM (CMSSM), the non-universal Higgs model (NUHM), the CPX scenario and a variant of the phenomenological MSSM (pMSSM). We find values of the CP-violating asymmetry ACP in b → sγ decay that may be as large as 3 %, so future measurements of ACP may provide independent information about CP violation in the MSSM. We find that CP-violating MSSM contributions to the Bs meson mass mixing term ΔMBs are in general below the present upper limit, which is dominated by theoretical uncertainties. If these could be reduced, ΔMBs could also provide an interesting and complementary constraint on the six CP-violating MSSM phases, enabling them all to be determined experimentally, in principle. We also find that CP violation in the h2,3τ+ - and h2,3 anti tt couplings can be quite large, and so may offer interesting prospects for future pp, e+e-, μ+μ- and γγ colliders. (orig.)

    Core collapse supernovae are dominated by weakly interacting neutrinos. This provides a unique opportunity for macroscopic parity violation. We speculate that parity violation in a strong magnetic field can lead to an asymmetry in the explosion and a recoil of the newly formed neutron star. We estimate the asymmetry from neutrino-polarized-neutron elastic scattering, polarized electron capture and neutrino-nucleus elastic scattering in a (partially) polarized electron gas.

    32 pages, 8 figures International audience We study squark flavour violation in the anomaly mediated supersymmetry broken (AMSB) minimal supersymmetric standard model. Analytical expressions for the three-generational squark mass matrices are derived. We show that the anomaly-induced soft breaking terms have a decreasing amount of squark flavour violation when running from the GUT to the weak scale. Taking into account inter-generational squark mixing, we work out non-trivial constraint...

  15. CP violation in p bar p colliders

    International Nuclear Information System (INIS)

    This paper presents a simple calculation to investigate the possibility of studying CP violation in the B-environment at present p bar p colliders. The authors' conclusion, based on the comparison of CDF, as an example of a standard detector, with a proposed bottom collider detector (BCD), is that observation of CP violation seems to be possible, though very hard, only with specifically designed detectors and with a high integrated luminosity

    Burning mouth syndrome (BMS) is a chronic pain condition. It has been described by the International Headache Society as "an intra-oral burning or dysesthetic sensation, recurring daily for more than 2 h/day for more than 3 months, without clinically evident causative lesions." BMS is frequently seen in women in the peri-menopausal and menopausal age group in an average female/male ratio of 7:1. The site most commonly affected is the anterior two-thirds of the tongue. The patient may also report taste alterations and oral dryness along with the burning. The etiopathogenesis is complex and is not well-comprehended. The more accepted theories point toward a neuropathic etiology, but the gustatory system has also been implicated in this condition. BMS is frequently mismanaged, partly because it is not well-known among healthcare providers. Diagnosis of BMS is made after other local and systemic causes of burning have been ruled out as then; the oral burning is the disease itself. The management of BMS still remains a challenge. Benzodiazepines have been used in clinical practice as the first-line medication in the pharmacological management of BMS. Nonpharmacological management includes cognitive behavioral therapy and complementary and alternative medicine (CAM). The aim of this review is to familiarize healthcare providers with the diagnosis, pathogenesis, and general characteristics of primary BMS while updating them with the current treatment options to better manage this group of patients.

  17. VIOLATION OF CONVERSATION MAXIM ON TV ADVERTISEMENTS

    2015-07-01

    Full Text Available Maxim is a principle that must be obeyed by all participants textually and interpersonally in order to have a smooth communication process. Conversation maxim is divided into four namely maxim of quality, maxim of quantity, maxim of relevance, and maxim of manner of speaking. Violation of the maxim may occur in a conversation in which the information the speaker has is not delivered well to his speaking partner. Violation of the maxim in a conversation will result in an awkward impression. The example of violation is the given information that is redundant, untrue, irrelevant, or convoluted. Advertisers often deliberately violate the maxim to create unique and controversial advertisements. This study aims to examine the violation of maxims in conversations of TV ads. The source of data in this research is food advertisements aired on TV media. Documentation and observation methods are applied to obtain qualitative data. The theory used in this study is a maxim theory proposed by Grice (1975. The results of the data analysis are presented with informal method. The results of this study show an interesting fact that the violation of maxim in a conversation found in the advertisement exactly makes the advertisements very attractive and have a high value.

    2015-01-01

    We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximize CP-violating observables subject to the experimental upper bounds on electric dipole moments. We also implement CP-conserving constraints from Higgs physics, flavour physics and the upper limits on the cosmological dark matter density and spin-independent scattering. We study possible values of observables within the constrained MSSM (CMSSM), the non-universal Higgs model (NUHM), the CPX scenario and a variant of the phenomenological MSSM (pMSSM). We find values of the CP-violating asymmetry A_CP in b -> s gamma decay that may be as large as 3%, so future measurements of A_CP may provide independent information about CP violation in the MSSM. We find that CP-violating MSSM contributions to the...

  19. A CP-Violating Kinematic Structure

    CERN Document Server

    Ahluwalia, D V

    2000-01-01

    A CP violating kinematic structure is presented. The essential physical input is to question the textbook wisdom, ``Now when a particle is at rest, one cannot define its spin as either left- or right-handed, so phi_R(0) = phi_L(0),'' as found, e.g., in Lewis Ryder's Quantum Field Theory, and in many other books on the representations of the Lorentz group. It is suggested that this equality is true only up to a phase. The demand of C, P, and T covariances, separately, fixes this phase to be pm 1. If these conditions are relaxed, a natural CP-violating kinematic structure emerges. Having established a CP-violating kinematic structure, we then discuss how Planck scale physics necessarily invokes non-commutative space-time and that such changes in the structure of space-time will force upon us additional violations/deformations of the CPT structure of space-time, and a violation of the principle of equivalence via a violation of the Lorentz symmetries. The latter may carry significant consequences for understandi...

  20. Waste: energy to burn

    International Nuclear Information System (INIS)

    Incinerated, transformed into fuel or a gas, waste is a versatile source of energy. It is as once a problem and a resource that is increasingly the focus of green policies. According to the 2009 World Waste Survey, between 3.4 and 4 billion tons of waste are produced each year worldwide. Leading the pack is China, with 300 million tons produced in 2005, followed closely by the United States, with 238 million tons. But the United States wins the per capita count with 760 kg of waste produced per year per inhabitant; Australia comes in second. In Europe, 500 kg of waste is produced per capita per year for a total of 2 billion tons generated annually, and a growth rate of 10% in ten years' time. Between 2/3 and 3/4 of these waste materials are sorted, and a portion of them is recycled. The rest is either carted away to a dumping ground, or incinerated. But this waste is primarily domestic, and still contains energy, energy that can be recovered. The added bonus is two-fold: an additional source of energy is created by transforming waste, called waste-to- wheel or waste-to-energy (WTE), and the decomposition of organic waste does not give off GHGs. Two ways are known today to transform wastes into energy: the thermal process, where heat is extracted from the waste (and sometimes converted into electricity), and the non-thermal process, which comprises collecting energy in a chemical form (biogas, biofuel). Both technologies depend on the type of waste to be treated: plastic materials, household refuse, fermentable elements, sludge residue from sewage treatment plants, agricultural waste, forestry industry waste, etc. The thermal process is by far the most widely employed. 74% of waste is incinerated in Japan, and around 30 to 55% in most European countries. The second process does not burn waste and is better suited to wet and organic matter, i.e., to waste that contains quantities of biomass: fermentable waste, sludge, agricultural waste and the gas given off at

    2013-10-01

    Burn control and passive safety in accident scenarios will be an important design consideration in future tokamaks, especially those used as a neutron source for fusion-fission hybrid reactors, such as the Subcritical Advanced Burner Reactor (SABR) concept. At Georgia Tech, we are developing a new burning plasma dynamics code to investigate passive safety mechanisms that could prevent power excursions in tokamak reactors. This code solves the coupled set of balance equations governing burning plasmas in conjunction with a two-point SOL-divertor model. Predictions have been benchmarked against data from DIII-D. We are examining several potential negative feedback mechanisms to limit power excursions: i) ion-orbit loss, ii) thermal instabilities, iii) the degradation of alpha-particle confinement resulting from ripples in the toroidal field, iv) modifications to the radial current profile, v) ``divertor choking'' and vi) Type 1 ELMs.

    2015-10-01

    Full Text Available A burn is a wound in which there is coagulative necrosis of the tissue, majority of which are caused by heat. Burn injury is a major public health problem in many areas of the world. Burns predispose to infection by damaging the protective barrier function of the skin, thus facilitating the entry of pa thogenic microorganisms and by inducing systemic immunosuppression . (1 OBJECTIVE : The present study was therefore undertaken to isolate and identify the aerobic bacterial flora in burn patients and its antibiotic susceptibility pattern. MATERIAL & METHODS : A total of 100 patients admitted with different degree of burns were studied. Wound swabs were taken with aseptic precautions by dry sterile cotton swab sticks. These swabs were transported to the microbiology laboratory and the isolates were identified based on standard microbiological methods. Antibiotic susceptibility testing was done by Kirby Bauer’s disc diffusion method. RESULT : A total of 127 bacterial pathogens were isolated from 100 patients. Of these, 69% were monomicrobial in nature and 28% wer e polymicrobial. The most frequent cause of infection was found to be Staphylococcus aureus (39.4%, followed by Pseudomonas aeruginosa (14.2%, Klebsiella pneumonia (13.4%, E.coli (8.7% and Acinetobacter species (7.9%.Out of the total Staphylococcus au reus isolates, 19 were Methicillin sensitive and 31 were Methicillin resistant (MRSA. All the MRSA strains were 100% sensitive to Vancomycin and Linezolid. The Pseudomonas aeruginosa isolates were most sensitive to Amikacin (9 4.4%, Fluroquinolones (61.1% . CONCLUSION : Staphylococcus aureus and Pseudomonas aeruginosa were major causes of infection in burn wounds. Therefore it is necessary to implement urgent measures for restriction of nosocomial infections, sensible limitation on the use of antimicrobial agents, strict disinfection and hygiene.

    The American Burn Association, Children's Burn Foundation, and Christian Medical College in Vellore, India have partnered together to improve pediatric burn care in Southern India. We report the demographics and outcomes of burns in this center, and create a benchmark to measure the effect of the partnership. A comparison to the National Burn Repository is made to allow for generalization and assessment to other burn centers, and to control for known confounders such as burn size, age, and mechanism. Charts from the pediatric burn center in Vellore, India were retrospectively reviewed and compared with data in the American Burn Association National Burn Registry (NBR) for patients younger than 16 years. One hundred nineteen pediatric patients with burns were admitted from January 2004 through April 2007. Average age was 3.8 years; average total body surface area burn was 24%: 64% scald, 30% flame, 6% electric. Annual death rate was 10%, with average fatal total body surface area burn was 40%. Average lengths of stay for survivors was 15 days. Delay of presentation was common (45% of all patients). Thirty-five of 119 patients received operations (29%). Flame burn patients were older (6.1 years vs 2.6 years), larger (30 vs 21%), had a higher fatality rate (19.4 vs 7.7%), and more of them were female (55 vs 47%) compared with scald burn patients. Electric burn patients were oldest (8.3 years) and all male. When compared with data in the NBR, average burn size was larger in Vellore (24 vs 9%). The mortality rate was higher in Vellore (10.1 vs 0.5%). The average mortal burn size in Vellore was smaller (40 vs 51%). Electric burns were more common in Vellore (6.0 vs 1.6%). Contact burns were almost nonexistent in Vellore (0.9 vs 13.1%). The differences in pediatric burn care from developing health care systems to burn centers in the US are manifold. Nonpresentation of smaller cases, and incomplete data in the NBR explain many of the differences. However, burns at this

    Demographers predict that the world population will double during the first half of the 21st century before it will begin to level off. In this volume, a group of prominent authors examine what societal changes must occur to meet this challenge to the natural environment and the transformational changes that we must experience to achieve sustainability. Frances Cairncross, Herman E. Daly, Stephen H. Schneider and others provide a broad discussion of sustainable development. They detail economic and environmental, as well as spiritual and religious, corporate and social, scientific and political factors. Sustainable Development: The Challenge of Transition offers many insightful policy recommendations about how business, government, and individuals must change their current values, priorities, and behavior to meet present and future challenges. It will appeal to scholars and decision makers interested in global change, environmental policy, population growth, and sustainable development, and also to corporate environmental managers.

  16. Local Sustainability

    International Nuclear Information System (INIS)

    The current polemic about the possibilities of sustainable development has led to a renovated interest for the topic of the sustainability of the communities and the local sustainability. In front of the global sustainability whose conditions have been exposed by systemic ecologists and for macro economists, the sustainability of specific places arises in the planet whose conditions are object of study of the ecology of landscapes, of the ecological economy, of the cultural anthropology, of the environmental sociology and naturally, of the integral environmentalism. In this discussion the Colombian case charges unusual interest to be one of the few countries of Latin America, where a very dense net of municipalities exists, each one with its urban helmet and with a position and some functions defined by the political constitution of the nation. This net of municipalities and of urban helmets it also constitutes net of alternative to the current macro-cephalic situation. As well as Bogota grew, in a hundred years, of less than a hundred thousand inhabitants to six million inhabitants, each one of these municipalities contains a potential of growth that depends on the characteristics of its ecological, social, economic and politic sustainability

    Infection is a major problem in burn care and especially when it is due to bacteria with hospital-acquired multi-resistance to antibiotics. Moreover, when these bacteria are Gram-negative organisms, the most effective molecules are 20 years old and there is little hope of any new product available even in the distant future. Therefore, it is obvious that currently available antibiotics should not be misused. With this aim in mind, the following review was conducted by a group of experts from the French Society for Burn Injuries (SFETB). It examined key points addressing the management of antibiotics for burn patients: when to use or not, time of onset, bactericidia, combination, adaptation, de-escalation, treatment duration and regimen based on pharmacokinetic and pharmacodynamic characteristics of these compounds. The authors also considered antibioprophylaxis and some other key points such as: infection diagnosis criteria, bacterial inoculae and local treatment. French guidelines for the use of antibiotics in burn patients have been designed up from this work. PMID:20510518

    Full Text Available Menopause is a physiological process typically occurring in the fifth decade of life. One of the most annoying oral symptoms in this age group is the burning mouth syndrome (BMS, which may be defined as an intraoral burning sensation occurring in the absence of identifiable oral lesion or laboratory findings. Pain in burning mouth syndrome may be described as burning, tender, tingling, hot, scalding, and numb sensation in the oral mucosa. Multiple oral sites may be involved, but the anterior two-third part and the tip of tongue are most commonly affected site. There is no definite etiology for BMS other than the precipitating causative factors, and it is still considered idiopathic. Various treatment options like use of benzodiazepine, anti-depressants, analgesics, capsaicin, alpha lipoic acids, and cognitive behavioral therapy are found to be effective, but definite treatment is still unknown. The present article discusses some of the recent concepts of etiopathogenesis of BMS as well as the role of pharmacotherapeutic management in this disorder.

    Full Text Available Introduction: Burning mouth syndrome is characterized by chronic oral pain or burning sensation affecting the oral mucosa in the absence of obvious visible mucosal lesions. Patient presenting with the burning mouth sensation or pain is frequently encountered in clinical practice which poses a challenge to the treating clinician. Its exact etiology remains unknown which probably has multifactorial origin. It often affects middle or old age women and it may be accompanied by xerostomia and altered taste. Objective: To review the current concepts regarding etiopathogenesis, diagnosis and management of this disorder. Methods and methodology: A literature review was conducted on PubMed/Medline and Google scholar about the burning mouth syndrome and the representative articles were selected and reviewed. Conclusion: There is no universal consensus regarding diagnosis, etiology and treatment of BMS. BMS is a diagnosis of exclusion which probably has multifactorial origin. Various pharmacological and non pharmacological treatments are available but it is difficult to achieve curative treatment so reassurance is of great importance while treating the patients. Combination of cognitive behavioral therapy, alpha lipoic acid and/or clonazepam has shown promising results.

    2012-07-01

    Fusion physics focuses on the complex behaviour of hot plasmas confined by magnetic fields with the ultimate aim to develop a fusion power plant. In the future generation of tokamaks like ITER, the power generated by the fusion reactions substantially exceeds the external input power (Pfusion}/Pin >= 10). When this occurs one speaks of a burning plasma. Twenty per cent of the generated fusion power in a burning plasma is carried by the charged alpha particles, which transfer their energy to the ambient plasma in collisions, a process called thermalization. A new phenomenon in burning plasmas is that the alpha particles, which form a minority but carry a large fraction of the plasma kinetic energy, can collectively drive certain types of magneto-hydrodynamic (MHD) modes, while they can suppress other MHD modes. Both types of MHD modes can have desirable effects on the plasma, as well as be detrimental to the plasma. For example, the so-called sawtooth instability, on the one hand, is largely responsible for the transport of the thermalized alpha particles out of the core, but, on the other hand, may result in the loss of the energetic alphas before they have fully thermalized. A further undesirable effect of the sawtooth instability is that it may trigger other MHD modes such as neoclassical tearing modes (NTMs). These NTMs, in turn, are detrimental to the plasma confinement and in some cases may even lead to disruptive termination of the plasma. At the edge of the plasma, finally, so-called edge localized modes or ELMs occur, which result in extremely high transient heat and particle loads on the plasma-facing components of a reactor. In order to balance the desired and detrimental effects of these modes, active feedback control is required. An additional complication occurs in a burning plasma as the external heating power, which is nowadays generally used for plasma control, is small compared to the heating power of the alpha particles. The scientific challenge

    2015-01-01

    The presence of R-parity violating interactions may relieve the tension between existing LHC constraints and natural supersymmetry. In this paper we lay down the theoretical framework and explore models of dynamical R-parity violation in which the breaking of R-parity is communicated to the visible sector by heavy messenger fields. We find that R-parity violation is often dominated by non-holomorphic operators that have so far been largely ignored, and might require a modification of the existing searches at the LHC. The dynamical origin implies that the effects of such operators are suppressed by the ratio of either the light fermion masses or the supersymmetry breaking scale to the mediation scale, thereby providing a natural explanation for the smallness of R-parity violation. We consider various scenarios, classified by whether R-parity violation, flavor breaking and/or supersymmetry breaking are mediated by the same messenger fields. The most compact case, corresponding to a deformation of the so called ...

We consider various scenarios, classified by whether R-parity violation, flavor breaking and/or supersymmetry breaking are mediated by the same messenger fields. The most compact case, corresponding to a deformation of the so called flavor mediation scenario, allows for the mediation of supersymmetry breaking, R-parity breaking, and flavor symmetry breaking in a unified manner.

  6. MINOS and CPT-violating neutrinos

    International Nuclear Information System (INIS)

    We review the status of CPT violation in the neutrino sector. Apart from LSND, current data favors three flavors of light stable neutrinos and antineutrinos, with both halves of the spectrum having one smaller mass splitting and one larger mass splitting. Oscillation data for the smaller splitting are consistent with CPT. For the larger splitting, current data favor an antineutrino mass-squared splitting that is an order of magnitude larger than the corresponding neutrino splitting, with the corresponding mixing angle less than maximal. This CPT-violating spectrum is driven by recent results from MINOS, but is consistent with other experiments if we ignore LSND. We describe an analysis technique which, together with MINOS running optimized for muon antineutrinos, should be able to conclusively confirm the CPT-violating spectrum proposed here, with as little as 3 times the current data set. If confirmed, the CPT-violating neutrino mass-squared difference would be an order of magnitude less than the current most-stringent upper bound on CPT violation for quarks and charged leptons.

  7. A review of hydrofluoric acid burn management.

    2014-01-01

    Hydrofluoric acid (HF) causes a unique chemical burn. Much of the current treatment knowledge of HF burns is derived from case reports, small case series, animal studies and anecdotal evidence. The management can be challenging because clinical presentation and severity of these burns vary widely. Plastic surgeons managing burn patients must have a basic understanding of the pathophysiology, the range of severity in presentation and the current treatment options available for HF burns. The present article reviews the current understanding of the pathophysiology and systemic effects associated with severe HF burns. Furthermore, it distinguishes between minor and life-threatening HF burns and describes several of the basic techniques that are available to treat patients with HF burns. PMID:25114621

    2011-01-01

    Full Text Available There have been many cases of burn patients who also suffer from psychiatric problems, including eating disorders. We present a case of a 38-year-old female with an eating disorder and depression who became light-headed and fell, spilling boiling water from a kettle on herself at home sustaining partial thickness and full thickness burns over 5% of her total body surface area: left buttock and right thigh and calf. Eating disorders (in the present case, anorexia nervosa cause emaciation and malnutrition, and consent for hospitalization from the patient and/or family is often difficult. During the medical treatment of burns for these patients, consideration not only of physical symptoms caused by malnutrition but also the psychiatric issues is required. Therefore, multifaceted and complex care must be given to burn patients with eating disorders.

  12. Communication Strength of Correlations Violating Monogamy Relations

    Kłobus, Waldemar; Oszmaniec, Michał; Augusiak, Remigiusz; Grudka, Andrzej

    2016-05-01

    In any theory satisfying the no-signaling principle correlations generated among spatially separated parties in a Bell-type experiment are subject to certain constraints known as monogamy relations. Recently, in the context of the black hole information loss problem it was suggested that these monogamy relations might be violated. This in turn implies that correlations arising in such a scenario must violate the no-signaling principle and hence can be used to send classical information between parties. Here, we study the amount of information that can be sent using such correlations. To this aim, we first provide a framework associating them with classical channels whose capacities are then used to quantify the usefulness of these correlations in sending information. Finally, we determine the minimal amount of information that can be sent using signaling correlations violating the monogamy relation associated to the chained Bell inequalities.

    We review the main theoretical motivations and observational constraints on Planck scale sup-pressed violations of Lorentz invariance. After introducing the problems related to the phenomenological study of quantum gravitational effects, we discuss the main theoretical frameworks within which possible departures from Lorentz invariance can be described. In particular, we focus on the framework of Effective Field Theory, describing several possible ways of including Lorentz violation therein and discussing their theoretical viability. We review the main low energy effects that are expected in this framework. We discuss the current observational constraints on such a framework, focusing on those achievable through high-energy astrophysics observations. In this context we present a summary of the most recent and strongest constraints on QED with Lorentz violating non-renormalizable operators. Finally, we discuss the present status of the field and its future perspectives. (orig.)

  14. Lorentz violation and black-hole thermodynamics

    International Nuclear Information System (INIS)

    We consider nonstandard photons from nonbirefringent modified Maxwell theory and discuss their propagation in a fixed Schwarzschild spacetime background. This particular modification of Maxwell theory is Lorentz-violating and allows for maximal photon velocities differing from the causal speed c of the asymptotic background spacetime. In the limit of geometrical optics, light rays from modified Maxwell theory are found to propagate along null geodesics in an effective metric. We observe that not every Lorentz-violating theory with multiple maximal velocities different from the causal speed c modifies the notion of the event horizon, contrary to naive expectations. This result implies that not every Lorentz-violating theory with multiple maximal velocities necessarily leads to a contradiction with the generalized second law of thermodynamics.

  15. Chiral Flavor Violation from Extended Gauge Mediation

    CERN Document Server

    Evans, Jared A; Thalapillil, Arun

    2015-01-01

    Models of extended gauge mediation, in which large A-terms arise through direct messenger-MSSM superpotential couplings, are well-motivated by the discovery of the 125 GeV Higgs. However, since these models are not necessarily MFV, the flavor constraints could be stringent. In this paper, we perform the first detailed and quantitative study of the flavor violation in these models. To facilitate our study, we introduce a new tool called FormFlavor for computing precision flavor observables in the general MSSM. We validate FormFlavor and our qualitative understanding of the flavor violation in these models by comparing against analytical expressions. Despite being non-MFV, we show that these models are protected against the strongest constraints by a special flavor texture, which we dub chiral flavor violation ($\\chi$FV). This results in only mild bounds from current experiments, and exciting prospects for experiments in the near future.

  17. Looking for Lorentz violation with gravitational waves

    CERN Document Server

    Schreck, M

    2016-01-01

    The current letter has been inspired by the recent direct detection of gravitational waves reported by Advanced LIGO. In this context, a particular Lorentz-violating framework for classical, massive particles is on the focus. The latter is characterized by a preferred direction in spacetime comprised of CPT-odd components with mass dimension 1. Curvature effects in spacetime, which are caused by a propagating gravitational wave, are assumed to deform the otherwise constant background field. In accordance with spontaneous Lorentz violation, a particular choice for the vector field is taken, which was proposed elsewhere. The geodesic equations for a particle that is subject to this type of Lorentz violation are obtained. Subsequently, their numerical solutions are computed and discussed. The particular model considered leads to changes in the particle trajectory, which interferometric gravitational-wave experiments could be sensitive for. Since such effects have not been observed in the gravitational-wave event...

  18. Unidirectionality of time induced by T violation

    2011-07-08

    The physical nature of time has been an enigma for centuries. Despite the progress made in linking various arrows of time together, the underlying reason for the observed direction of time has remained a deep mystery. However, an increasing number of experiments are confirming a violation of time reversal invariance (T) in meson decay processes. T violation represents a fundamental break in the symmetry between the past and future. I show here that such processes induce destructive interference between different paths that the universe can take through time. The interference eliminates all paths except for two that represent continuously forwards and continuously backwards time evolution. These results illustrate that there are previously-unknown large-scale physical effects arising from the T violation processes in meson decay. Moreover these effects offer a solution to the age-old problem of the cause of the unidirectionality of time.

  19. T-violation experiments using Moessbauer transitions

    International Nuclear Information System (INIS)

    We analyse the effects of time-reversal (T) violation on the transmission of photons through a system of magnetized foils that have a Moessbauer transition with comparable M1 and E2 strength (e.g. 99Ru or 197Au). We consider experiments that are true tests of T violation and therefore are not subject to effects from final-state interactions, discussing observables that probe either parity-violating or parity-conserving T-odd interactions. We propose a novel three-foil experiment sensitive to a T-odd, P-odd multipole admixture. This experiment should be insensitive to most systematic problems faced by the earlier experiments. (orig.)

    Abel, S.; Branco, G. C.; Khalil, S.

    2003-09-01

    We show that the quark flavour structure and CP violating phenomena are strongly correlated in supersymmetric theories. For a generic pattern of supersymmetry breaking the two broad categories of Yukawa couplings, democratic and hierarchical textures, have entirely different phenomenological implications. With hierarchical Yukawas, the rephasing invariant phase, arg(VusVcbVcb∗Vcs∗), in the CKM mixing matrix has to be of order unity, while the SUSY CP violating phases are severely constrained by electric dipole moments, giving rise to the so-called SUSY CP problem. With democratic Yukawas, all experimental CP results can be accommodated with small values for the CKM and SUSY CP violating phases (i.e., CP can be considered as an approximate symmetry at the high energy scale). We also show that within this scenario, an entirely real CKM matrix in supersymmetric models is still allowed by the present experimental results.

  6. Structural Violence as a Human Rights Violation

    Directory of Open Access Journals (Sweden)

    KATHLEEN HO

    2007-09-01

    Full Text Available Human rights literature up to this point has not adequately addressed what it means to havestructural violations of human rights. This essay uses the theory of structural violence to illuminatehow structural inequalities that systematically deny some people their basic human needs constitute astructural violation of human rights. In making this argument, structural violence theorists defineviolence as the avoidable disparity between the potential ability to fulfill basic needs and their actualfulfillment. The theory further locates the unequal share of power to decide over the distribution ofresources as the pivotal causal factor of these avoidable structural inequalities. Recognizing thatstructural causes are responsible for constrained agency is pivotal in making the transition fromstructural violence to structural violations of human rights. It is the effect of structures on individualagency that results in this gap between potential and actual fulfillment of rights. This essay usesThomas Pogge and Amartya Sen’s work on poverty to substantiate this claim that when agency isconstrained to the extent that fundamental human needs cannot be attained, structural violencebecomes a structural violation of human rights. Applying structural violence to the human rightsdiscourse, there emerges a clear emphasis on the need for special protection of social and economicrights that have for too long been marginalized in favor of civil and political rights. Moreover, theright to development directly addresses concerns raised by the structural violence theory. Specifically,this right recognizes how the unequal distribution of power in global financial institutions and traderegimes results in global inequality and therefore insists on international assistance and cooperationto remedy this glaring injustice. Finally, Audrey Chapman’s ‘violations approach’ is examined as apossible alternative to the current monitoring mechanism for social and economic

    We revisit the topic of triple-product asymmetries which probe CP violation through differential distributions. We construct distributions with well-defined discrete symmetry properties and characterize the asymmetries formed upon them. It is stressed that the simplest asymmetries may not be optimal. We explore systematic generalizations having limited reliance on the process dynamics and phase-space parametrization. They exploit larger fractions of the information contained in differential distributions and may lead to increased sensitivities to CP violation. Our detailed treatment of the case of spinless four-body decays paves the way for further experimental studies.

    We investigate bounds from tree-level and one-loop processes in generic supersymmetric models with spontaneous R-parity breaking in the superpotential. We analyse the bounds from a general point of view. The bounds are applicable both for all models with spontaneous R-parity violation and for explicit bilinear R-parity violation based on general lepton-chargino and neutrino-neutralino mixings. We find constraints from semileptonic B, D and K decays, leptonic decays of the mu and tau, electric dipole moments, as well as bounds for the anomalous magnetic moment of the muon.

It is shown that, as in the standard electroweak model, spontaneous CP violation can be achieved in the left-right symmetric and partially ununified models through extension of the Higgs sector and inclusion of an appropriate discrete symmetry. The experimental constraints on flavour changing neutral current in these models are also discussed. (author). 25 refs., 2 figs

    2001-01-01

    Cosmological limits on Lorentz invariance breaking in Chern-Simons $(3+1)-dimensional$ electrodynamics are used to place limits on torsion. Birefrigence phenomena is discussed by using extending the propagation equation to Riemann-Cartan spacetimes instead of treating it in purely Riemannian spaces. The parameter of Lorentz violation is shown to be proportional to the axial torsion vector which allows us to place a limit on cosmological background torsion from the Lorentz violation constraint which is given by $ 10^{-33} eV <|S^{\\mu}| < 10^{-32} eV$ where $|S^{\\mu}|$ is the axial torsion vector.

  5. Isospin-violating mixing in meson nonets

    International Nuclear Information System (INIS)

    Segregation into ideally mixed nonets results when the OZI-violating interaction which would mix u anti u, d anti d, and s anti s mesons into isospin and SU(3) eigenstates is much weaker than the s anti s-d anti d mass difference. We show that the d anti d-u anti u mass difference can begin to induce a similar segregation into d anti d and anti u mesons which leads to large isospin violations. An experimental example of such large isospin breaking (approx. 30%) which we predict has probably already been seen in f → K anti K. (orig.)

Time dependent rate asymmetries in K0 decays and the longitudinal muon polarization in KL → μ+μ- are also discussed. 50 refs., 3 figs., 1 tab. (Author)

    Measurements of parity-violating longitudinal analyzing powers (normalized asymmetries) in polarized proton-proton scattering provide a unique window on the interplay between the weak and strong interactions between and within hadrons. Several new proton-proton parity violation experiments are presently either being performed or are being prepared for execution in the near future: at TRIUMF at 221 MeV and 450 MeV and at COSY (Kernforschungsanlage Juelich) at 230 MeV and near 1.3 GeV. These ex...

  8. Higgs-induced lepton flavor violation

    International Nuclear Information System (INIS)

    Due to the smallness of the lepton Yukawa couplings, higher-dimensional operators can give a significant contribution to the lepton masses. In this case, the lepton mass matrix and the matrix of lepton-Higgs couplings are misaligned leading to lepton flavor violation (LFV) mediated by the Standard Model Higgs boson. We derive model-independent bounds on the Higgs flavor violating couplings and quantify LFV in decays of leptons and electric dipole moments for a class of lepton-Higgs operators contributing to lepton masses. We find significant Higgs-mediated LFV effects, especially if they involve virtual τ's. (orig.)

  9. CP violation in B meson decays

    2003-06-01

    CP violation in neutral B meson decays has been observed confirming the prediction of the Kobayashi-Maskawa model where introduction of six quaks naturally induces CP violation in the weak interaction. The measurements of CP asymmetryc in B meson decays were made at the newly constructed Asymmetric B factories, which consist of high luminosity, ebergy-asymmetric e+e- colliders (KEKB and PEP-II) and detectors (Belle and BaBar). The results are in good agreement and are consistent with other experimental results within the framework of the Standard Model.

    2016-01-01

    Recent measurements of CPT violation and Lorentz symmetry breaking in $B^0-\\bar{B}^0$ mixing and $B^0_s-\\bar{B}^0_s$ mixing, obtained from data taken by the LHCb experiment, are highlighted. The results are expressed in terms of the Standard-Model Extension (SME) coefficients, which incorporate both CPT and Lorentz violation. Due to the large boost of the $B$ mesons at LHCb, the SME coefficients can be determined with high precision. The bounds on these coefficients are improved significantly compared to previous measurements.

    2014-01-01

    $CP$ Violation is one of the necessary ingredients to produce the mat- ter anti-matter asymmetry we observe in the Universe today. The LHCb experiment is a general purpose forward-spectrometer located along the LHC proton-proton collider at CERN and is ideally suited for the in- vestigation of such phenomena. We present the latest results of 3-body charmless $B$ decays where large local $CP$ violating effects have been ob- served across various regions of the phase space. These results are discussed in the light of recent theoretical developments that attempt to understand the origin of the large asymmetries and their impact on future amplitude analyses.

    We present a search for CP violation in single top quark production with the DØ experiment at the Tevatron proton-antiproton collider. CP violation in the top electroweak interaction results in different single top quark production cross sections for top and antitop quarks. We perform the search in the single top quark final state using 5.4 fb-1 of data, in the s-channel, t-channel, and for both combined. At this time, we do not see an observable CP asymmetry.

In retrospect, it seems we’ve been pretty draconian in rejecting transport modes that have failed in the market p...

  15. Nuclear power for sustainable development

    International Nuclear Information System (INIS)

    Energy demand continues to grow in spite of drastic efforts, especially in OECD countries for efficiency and energy savings. At the same time, the concept of sustainable development is calling for the alleviating and/or mitigating of environmental impacts. A limited number of options, that are technically mature and economically competitive, can substitute fossil fuel burning for electricity generation. Nuclear power is one of the electricity generating options that can contribute to an environmentally friendly development. The paper investigates the potential role of nuclear power in global energy supply up to 2050 and analyses the opportunities and challenges, for governments and nuclear industries, of a broad nuclear power deployment in response to environmental concerns. It concludes that, in the long term, increasing substantially the share of nuclear power in electricity generation is feasible and would contribute significantly to enhancing the sustainability of energy supply systems world-wide.

    In the Standard Model of particle physics, lepton flavour and lepton number are conserved quantities although no fundamental symmetry demands their conservation. I present recent results of searches for lepton flavour and lepton number violating hadron decays measured at the B factories and LHCb. In addition, the LHCb collaboration has recently performed a search for the lepton flavour violating decay $\\tau^- \\mu^- \\mu^- \\mu^+$ The obtained upper exclusion limit, that has been presented in this talk for the first time, is of the same order of magnitude as those observed at the B factories. This is the first search for a lepton flavour violating $\\tau$ decay at a hadron collider.

    1983-06-01

    A case of hydrofluoric acid (HF) burns of the eye is reported and a review is presented of our investigation into the mechanism of HF toxicity in ocular tissues. A number of therapeutic procedures that have been successful in the treatment of HF skin burns were studied in the rabbit for use in the eye. Immediate single irrigation with water, normal saline or isotonic magnesium chloride solution is the most effective therapy for ocular HF burns. Extrapolation of other skin burn treatments to use in the eye is unacceptable due to the toxicity of these agents in normal eyes and the additive damage caused in burned eyes. PMID:6886845

    Full Text Available Burn injuries are a huge public health issue for children throughout the world, with the majority occurring in developing countries. Burn injuries can leave a pediatric patient with severely debilitating and deforming contractures, which can lead to significant disability when left untreated. Rehabilitation is an essential and integral part of pediatric burn treatment. The aim of this article was to review the literature on pediatric burn rehabilitation from the Medline, CINAHL, and Web of Science databases. An attempt has been made to present the basic aspects of burn rehabilitation, provide practical information, and discuss the goals and conceptualization of rehabilitation as well as the development of rehabilitation philosophy and strategies.

    Full Text Available The hand is ranked among the three most frequent sites of burns scar contracture deformity. One of the major determinants of the quality of life in burns survivors is the functionality of the hands. Burns deformities, although largely preventable, nevertheless do occur when appropriate treatment is not provided in the acute situation or when they are part of a major burns. Reconstructive procedures can greatly improve the function of the hands. Appropriate choice of procedures and timing of surgery followed by supervised physiotherapy can be a boon for a burns survivor.

    The quest for a year round tan has led to an increase in the use of artificial tanning devices, namely sunbeds. There has been much debate in the press recently regarding the dangers of sunbed use and calls for tighter regulation of the industry, particularly the licensing of unmanned tanning salons. The dangers of sunbed use have long been recognised and the body of evidence linking sunbed use to skin malignancy is growing, in fact this month the Lancet published a review from the International Agency for Research on Cancer classifying UV emitting tanning devices as carcinogenic to humans. At the Welsh Centre for Burns and Plastic Surgery we noticed a rise in the number of patients presenting with burns related to sunbed use and present our data surrounding this injury over the last 6 years.

    growth of human keratinocyte stem cells capable of producing epithelia for large-scale grafting in burns and maintain long-term functionality as a self-renewing tissue. The normal functioning of such an in vitro constructed graft under long-term artificial growth conditions is limited by the difficulties of maintaining the epidermal stem cell compartment. An apparent answer to this problem of stem cell depletion during autograft preparation would be to start with a pure population of progenitor stem cells and derive sustainable autograft from them. We have been aiming to this solution and currently attempting to isolate a pool of epidermal progenitor cells using Mebiol gel, which is a Thermo-Reversible Gelation polymer and was shown by others to support the growth of multi-potent skin-derived epithelial progenitor-1 cells. Additionally, the usefulness of Mebiol gel in maintaining epidermal stem cell compartment without FBS and/or animal origin feeder cells is being investigated by our group.

    Major burn patients have characteristics that make them especially susceptible to candidemia, but few studies focused on this have been published. The objectives were to evaluate the epidemiological, microbiological and clinical aspects of candidemia in major burn patients, determining factors associated with a poorer prognosis and mortality. We conducted a retrospective observational study of candidemia between 1996 and 2012 in major burn patients admitted to the La Fe University Hospital, Valencia, Spain. The study included 36 episodes of candidemia in the same number of patients, 55.6% men, mean age 37.33 years and low associated comorbidity. The incidence of candidemia varied between 0.26 and 6.09 episodes/1000 days stay in the different years studied. Candida albicans was the most common species (61.1%) followed by Candida parapsilosis (27.8%). Candidemia by C. krusei, C. glabrata or C. tropicalis were all identified after 2004. Central vascular catheter (CVC) was established as a potential source of candidemia in 36.1%, followed by skin and soft tissues of thermal injury (22.2%) and urinary tract (8.3%). Fluconazole was used in 19 patients (52.7%) and its in vitro resistance rate was 13.9%. The overall mortality was 47.2%, and mortality related to candidemia was 30.6%. Factors associated with increased mortality were those related to severe infection and shock. CVC was the most usual focus of candidemia. Fluconazole was the most common antifungal drug administered. The management of candidemia in major burn patients is still a challenge. PMID:26931414

    2006-05-01

    Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open system with an impedance and capacity-matched persistent exergy source. Irreversible and nonequilibrium thermodynamic concepts are combined with self-organizing systems theories as well as nonlinear control and stability analyses to explain this definition. In particular, this paper provides a missing link in the analysis of self-organizing systems: a tie between irreversible thermodynamics and Hamiltonian systems. As a result of this work, the concept of ''on the edge of chaos'' is formulated as a set of necessary and sufficient conditions for stability and performance of sustainable systems. This interplay between exergy rate and irreversible entropy production rate can be described as Yin and Yang control: the dialectic synthesis of opposing power flows. In addition, exergy is shown to be a fundamental driver and necessary input for sustainable systems, since exergy input in the form of power is a single point of failure for self-organizing, adaptable systems.

  12. Okanagan indoor wood burning appliance inventory survey

    International Nuclear Information System (INIS)

    A survey was conducted to determine the usage and nature of wood burning appliances used by residents in British Columbia's Okanagan region. The objective was to better understand this source of air quality concern and to facilitate strategic planning, guidelines and legislation. The survey also provides a baseline to track the effectiveness of any reduction strategies. It identifies the different types of wood burning appliances used in the community and presents residential options about potential bylaws to protect air quality. The receptivity of households to switch to more efficient wood burning appliances was also examined. The survey completes a portion of an overall emissions inventory for the Okanagan Valley. Environment Canada uses the particulate loading results to model the air quality in the airshed. Results showed that approximately 21 per cent of the households in the Okanagan use indoor wood burning appliances, and burn an average of 2.3 cords of wood each year. Only 11 per cent of the appliances are considered to have advanced burning technology. It is projected that the use of wood burning appliances in the Okanagan will increase by 5 to 7 per cent in the next 2 years. Most residents have good burning habits, but some improvements can still be made. Many residents are considering exchanging old wood burning appliances for clean burning technology appliances for environmental and health reasons. Most households would support a bylaw to control nuisance amounts of smoke from wood burning appliances. 20 tabs., 5 figs

    Lignites burning in the Greek Coal Power Plants (CPP) contain naturally occurring radionuclides mainly arising from the uranium series. Radium-226 concentrations in lignites burning in the three Coal Power Plants of the 3.02 GW energy centre, the greatest in Greece (Valley of Ptolemais, North Greece), varied from about 30 to 132 Bq kg-1 (average 65.5 Bq kg-1. About 1.3 % of 226 Ra is discharged to the environment in particulate form - fly ash - by the stacks of thermal power stations, burning coal at a rate 14.3 Mt (GH y)-1. The collective effective dose equivalent (EDE) commitment to the population 44400 living in the region of these plants, due to inhalation was estimated to be 0.13 man Sv y-1, that is an order of magnitude higher than that recommended for such a population. Doses from inhaled radon and radon progeny might cause an excess of 3-7 cancer deaths this year. (author)

  14. Wound Care in Burn Patients

    Full Text Available Wound care in one of the most important prognostic factors in burn victims. Open wound carries risks for infection due to hypothermia, protein and fluid losses. In addition, unhealed wounds are the major risk factors for acute-subacute or chronic complications in burn patients. Although no exact algorithm exists for open wound treatment, early escarectomy or debridement together with grafting is the best option. Ointments together with topical epithelizing agents without dressings are genereally adequate for first-degree burns. However, topical antibacterial agents are usually required for second to third-degree wounds. Standart treatment for the open wound without epithelization is autologous skin grafting. In cases where more than 50% of the skin surface in affected, autologus donor skin may not be enough. For these cases, epidermal cell culture in vitro may be used. Mesenchymal stem cell applications which have immunosupressive effects should be utilized in cases where cells need to be prepared as allografts.

    2010-09-30

    Radiation injuries are usually caused by radioactive isotopes in industry. Detonations of nuclear reactors, the use of military nuclear weapons, and terrorist attacks represent a risk of mass burn casualties. Ionizing radiation creates thermal burns, acute radiation syndrome with pancytopenia, and a delayed cutaneous syndrome. After a latency period, skin symptoms appear and the depth of tissue damages increase with dose exposure. The usual burn resuscitation protocols have to be applied. Care of these victims also requires assessment of the level of radiation, plus decontamination by an experienced team. In nuclear disasters, the priority is to optimize the available resources and reserve treatment to patients with the highest probability of survival. After localized nuclear injury, assessment of burn depth and surgical techniques of skin coverage are the main difficulties in a burn centre. Training in medical facilities and burn centres is necessary in the preparation for management of the different types of burn injuries. PMID:21991218

  1. New signatures of flavor violating Higgs couplings

    Science.gov (United States)

    Buschmann, Malte; Kopp, Joachim; Liu, Jia; Wang, Xiao-Ping

    2016-06-01

    We explore several novel LHC signatures arising from quark or lepton flavor violating couplings in the Higgs sector, and we constrain such couplings using LHC data. Since the largest signals are possible in channels involving top quarks or tau leptons, we consider in particular the following flavor violating processes: (1) pp → thh (top plus di-Higgs final state) arising from a dimension six coupling of up-type quarks to three insertions of the Higgs field. We develop a search strategy for this final state and demonstrate that detection is possible at the high luminosity LHC if flavor violating top-up-Higgs couplings are not too far below the current limit. (2) pp → tH 0, where H 0 is the heavy neutral CP-even Higgs boson in a two Higgs doublet model (2HDM). We consider the decay channels H 0 → tu, WW, ZZ, hh and use existing LHC data to constrain the first three of them. For the fourth, we adapt our search for the thh final state, and we demonstrate that in large regions of the parameter space, it is superior to other searches, including searches for flavor violating top quark decays ( t → hq). (3) H 0 → τ μ, again in the context of a 2HDM. This channel is particularly well motivated by the recent CMS excess in h → τ μ, and we use the data from this search to constrain the properties of H 0.

Furthermore, for a given value of m{sub 0}, there are two solutions for the two Majorana phases α{sub 21} and α{sub 31}, whereas the Dirac phase δ is arbitrary. For (ii), the parameters of m{sub 0}, δ, α{sub 21}, and α{sub 31} can be completely determined. We calculate the CP-violating asymmetries in neutrino–antineutrino oscillations for both mass textures of (i) and (ii), which are closely related to the CP-violating Majorana phases.

In the first part we present a formulation of partial compositeness in terms of a flavour symmetry group and a set of spurions, whose background values specify the symmetry breaking pattern. In such a framework we construct the complete set of dimension-six operators describing lepton flavour violation and CP violation. By exploiting the existing bounds, we derive limits on the compositeness scale in different scenarios, characterised by increasing restrictions on the spurion properties. We confirm that in the most general case the compositeness scale should lie well above 10 TeV. However, if in the composite sector the mass parameters and Yukawa couplings are universal, such a bound can be significantly lowered, without necessarily reproducing the case of minimal flavour violation. The most sensitive processes are decays of charged leptons either of radiative type or into three charged leptons, μ→e conversion in nuclei and the electric dipole moment of the electron. In the second part we explicitly compute the Wilson coefficients of the relevant dimension-six operators in the so-called two-site model, embodying the symmetry breaking pattern discussed in our first part, and we compare the results with those of the general spurion analysis.

    This short note is devoted to deriving scaling but hyperscaling violating solutions in a generalised Einstein-Maxwell-Dilaton theory with an arbitrary number of scalars and vectors. We obtain analytic solutions in some special case and discuss the physical constraints on the allowed parameter range in order to have a well-defined holographic ground-state solution.

    An optical field produced by intracavity four-wave mixing is shown to exhibit the following nonclassical features: photon antibunching, squeezing, and violation of Cauchy-Schwarz and Bell's inequalities. These intrinsic quantum mechanical effects are shown to be associated with the nonexistence of a positive normalizable Glauber-Sudarshan P function.

    This book contains the proceedings of the third international workshop on “From Parity Violation to Hadronic Structure and more ...” which was held from May 16 to May 20, 2006, at the George Eliopoulos conference center on the Greek island of Milos. It is part of a series that started in Mainz in 2002 and was followed by a second workshop in Grenoble in 2004. While originally initiated by the extraction of the strangeness contribution to the electromagnetic form factors of the nucleon, the workshop series has continuously broadened the focus to the application of Parity Violation using hadronic probes and to Parity Violation experiments in atomic physics. Meanwhile there have been many exciting new proposals for using Parity Violation in other areas like in the search for new physics beyond the standard model or in exploring hadron structure. There are also close connections to the open question on the size of the two photon exchange amplitude. Fifty years after the 1956 proposal of Lee and Yang to test t...

  19. CP violations in predictive neutrino mass structures

    International Nuclear Information System (INIS)

    We study the CP-violation effects from two types of neutrino mass matrices with (i) (Mν)ee=0, and (ii) (Mν)ee=(Mν)eμ=0, which can be realized by the high-dimensional lepton number violating operators ℓ-barRcγμLL(DμΦ)Φ2 and ℓ-barRclR(DμΦ)2Φ2, respectively. In (i), the neutrino mass spectrum is in the normal ordering with the lightest neutrino mass within the range 0.002 eV≲m0≲0.007 eV. Furthermore, for a given value of m0, there are two solutions for the two Majorana phases α21 and α31, whereas the Dirac phase δ is arbitrary. For (ii), the parameters of m0, δ, α21, and α31 can be completely determined. We calculate the CP-violating asymmetries in neutrino–antineutrino oscillations for both mass textures of (i) and (ii), which are closely related to the CP-violating Majorana phases

We analyze the conditions under which the CP-violating effects in such processes vanish, in terms of the minimal set of rephasing invariants, giving special attention to the dependence on the extra CP-violating parameters that are due to the Majorana nature of the neutrinos.

    Supersymmetric models where R-parity is broken via lepton number violation provides an intrinsically supersymmetric explanation for the observed neutrino. The complex phases of the corresponding parameters are constrained by the observed matter anti-matter asymmetry of the universe. Taking bilinear R-parity violation as framework in combination with the assumption of a large lepton asymmetry generated via the Affleck-Dine mechanism at the end of inflation we investigate these constraints in the parameter range compatible with neutrino data.

    2009-05-01

    Research in magnetically confined fusion is now approaching a major milestone which is in evaluating and controlling burning plasma conditions. This milestone will be first met in the ITER experiment, presently being built in Cadarache, France through an international partnership, which includes China, the European Union, India, Japan, South Korea, Russia and the United States. In order to achieve its mission of achieving burning plasma conditions, and possibly ignition, a comprehensive set of scientific instruments (diagnostics) is being planned. That set represents the culmination of more than 50 years of development and research. More than 40 plasma parameters will be measured, including many which will be directly controlled. Some of these measurements will be done for the first time, such as probing the production, distribution and behavior of fusion produced, i.e. alpha particles, a key element in sustaining the fusion reaction process. These measurements will need to be done in a hostile environment, where a large nuclear radiation field, substantial direct particle flux, long pulse length and lack of direct access will bring severe constraints. Furthermore, the needs of the experiment will demand high reliability, low maintenance and the ability to retain a good calibration over a long period of time. We will review the challenges of the task and the opportunities for scientific breakthroughs from these state-of-the-art diagnostics instruments, as they pertain to the specific context of burning plasma conditions, together with examples of where these measurements will directly impact our scientific understanding and ability to control these conditions.

    2011-01-01

    Full Text Available Objective: Hand burns are common injuries. Children frequently sustain burn injuries, especially to their hands. Contractures are a common sequel of severe burns around joints. The prepuce, or foreskin, has been used as a skin graft for a number of indications. We conducted this study to evaluate the feasibility of utilising the preputial skin for the management of post-burn contractures of fingers in uncircumcised male children. Materials and Methods: Preputial skin was used for the coverage of released contractures of fingers in 12 patients aged 2-6 years. The aetiology of burns was "Kangri" burn in eight patients and scalding in four patients. Six patients had contracture in two fingers, four patients in one finger, and two patients had contractures in three fingers. Results: None of the patients had graft loss, and all the wounds healed within 2 weeks. All patients had complete release of contractures without any recurrence. Hyperpigmentation of the grafts was observed over a period of time, which was well accepted by the parents. Conclusions: Preputial skin can be used successfully for male children with mild-to-moderate contractures of 2-3 fingers for restoration of the hand function, minimal donor site morbidity.

  3. Carbon production on accreting neutron stars in a new regime of stable nuclear burning

    CERN Document Server

    Keek, L

    2015-01-01

    Accreting neutron stars exhibit Type I X-ray bursts from both frequent hydrogen/helium flashes as well as rare carbon flashes. The latter (superbursts) ignite in the ashes of the former. Hydrogen/helium bursts, however, are thought to produce insufficient carbon to power superbursts. Stable burning could create the required carbon, but this was predicted to only occur at much larger accretion rates than where superbursts are observed. We present models of a new steady-state regime of stable hydrogen and helium burning that produces pure carbon ashes. Hot CNO burning of hydrogen heats the neutron star envelope and causes helium to burn before the conditions of a helium flash are reached. This takes place when the mass accretion rate is around 10% of the Eddington limit: close to the rate where most superbursts occur. We find that increased heating at the base of the envelope sustains steady-state burning by steepening the temperature profile, which increases the amount of helium that burns before a runaway can...

  4. A thematic study of the role of social support in the body image of burn survivors

    Directory of Open Access Journals (Sweden)

    Kellie Hodder

    2014-01-01

    Full Text Available There is evidence that social support is important for the development and mainte- nance of body image satisfaction for people who have sustained burn injuries. This qualitative study explored the specific mechanisms by which social support impacts the body image satisfaction of burn survivors, drawing on nine participants’ in depth accounts. Participants were recruited through a burns unit at a public hospital in South Australia. Interviews were conducted with nine female burn survivors aged between 24 and 65 (mean age 44.6. Participants described their perceptions about their appearance post burn and their social support experiences. Four themes were identified: acceptance, social comparison, talking about appearance concerns, and the gaze of others. Results indicate that for these participants, social support was an important factor in coming to terms with changes in appearance, specifically support that helps to minimise feelings of difference. Unhelpful aspects of social support were also identified included feeling that suffering was being dismissed and resenting the perceived expectation from supports to be positive. Social supports are important to consider in relation to body image for those working with people who have survived burn injuries.

    2003-06-01

    Given the increased level of adrenergic stimulation in burn patients, it would be expected that they would experience an increased incidence of cardiac arrhythmias and other cardiac events. We performed a retrospective chart review of 56 acute burn patients matched by age, length of hospital stay, and sex to 56 trauma patients, all of whom had been continuously monitored electrocardiographically. Burn and trauma patients were similar in injury severity, admission laboratory values, and prior history of cardiopulmonary diseases. Arrhythmias were noted in 34% of burn patients and 28% of trauma patients. One myocardial infarction and six deaths occurred in burn patients. No myocardial infarctions or deaths were observed in trauma patients. A past history of cardiopulmonary disease increased the risk of myocardial infarction or death by 6.6 times. Cardiac arrhythmias and other events are relatively infrequent and benign in burn patients and are similar to those experienced by other patients with acute injuries. PMID:12781616

  9. High-burn-up fuels for fast reactors. Past experience and novel applications

    International Nuclear Information System (INIS)

    Fast reactors in the U.S. routinely achieved fuel burn-ups of 10%, with some fuel able to reach peak burn-ups of 20%, notably in the Experimental Breeder Reactor II and the Fast Flux Test Facility. Maximum burn-up has historically been constrained by chemical and mechanical interactions between the fuel and its cladding, and to some extent by radiation damage and thermal effects (e.g., radiation-induced creep, thermal creep, and radiation embrittlement) that cause the cladding to weaken. Although fast reactors have used several kinds of fuel - including oxide, metal alloy, carbide, and nitride - the vast majority of experience with fast reactors has been using oxide (including mixed oxide) and metal-alloy fuels based on uranium. Our understanding of high-burn-up operation is also limited by the fact that breeder reactor programs have historically assumed that their fuel would eventually undergo reprocessing; the programs thus have not made high burn-up a top priority. Recently a set of novel designs have emerged for fast reactors that require little initial enrichment and no reprocessing. These reactors exploit a concept known as a traveling wave (sometimes referred to as a breed-and-burn wave, fission wave, or nuclear-burning wave). By breeding and using its own fuel in place as it operates, a traveling-wave reactor can obtain burn-ups that approach 50%, well beyond the current base of knowledge and experience. Our computational work on the physics of traveling-wave reactors shows that they require metal-alloy fuel to provide the margins of reactivity necessary to sustain a breed-and-burn wave. This paper reviews operating experience with high-burn-up fuels and the technical feasibility of moving to a qualitatively new burn-up regime. We discuss our calculations on traveling-wave reactors, including those concerning the possible use of thorium. The challenges associated with high burn-up and fluence in fuels and materials are also discussed. (author)

  10. Building a sustainable future

    International Nuclear Information System (INIS)

    Nuclear technology offers unique tools in the quest for sustainable development. Such technology is often the best to gather information and provide solutions that would not otherwise be possible or practical: to diagnose and treat disease, to breed better crops and fight insect pests; to assess new sources of fresh water; and to monitor pollution. While many may only think of energy, nuclear technology has a much larger role to play in human development. Where it can make a difference, the International Atomic Energy Agency (IAEA) provides support to 134 Member States for using this technology to solve the important challenges they face. Isotopes, stable and radioactive forms of chemical elements, can be used to 'label' materials under study. Since both stable and radioactive isotopes can be identified and measured using appropriate equipment, labelling is often used in diagnostic medical tests, in studies of underground sources of water, and to trace pollutants, such as heavy metals and pesticides. Stable, non-radioactive, isotopes are used in nutritional studies to trace the metabolism of vitamins and trace minerals in supplements. Other nuclear techniques use radiation which can be focussed into beams and depending on the intensity, can be used to kill cancer cells, to sterilize tissue grafts for burn victims, to sterilize food against insects or disease causing pathogens, to make insects sterile so they cannot reproduce, to induce desirable genetic changes in crops, or to scan body organs for abnormalities

A burn destroys the aesthetic features and lines of the lip. Plastic and reconstructive surgery of the face has a long history. Many local and regional flaps have been used for reconstruction of surgical or traumatic defects. Procedures to enhance the cosmetic features of the ...

  13. Comparison of tokamak burn cycle options

    International Nuclear Information System (INIS)

    Experimental confirmation of noninductive current drive has spawned a number of suggestions as to how this technique can be used to extend the fusion burn period and improve the reactor prospects of tokamaks. Several distinct burn cycles, which employ various combinations of Ohmic and noninductive current generation, are possible, and we will study their relative costs and benefits for both a commerical reactor as well as an INTOR-class device. We begin with a review of the burn cycle options

    In the last two decades, much progress has been made in the control of burn wound infection and nasocomial infections (NI) in severely burned patients. The continiually changing epidemiology is partially related to greater understanding of and improved techniques for burn patient management as well as effective hospital infection control measures. With the advent of antimicrobial chemotherapeutic agents, infection of the wound site is now not as common as, for example, urinary and blood strea...

    Some aspects of the stress response during acute intensive care for severe burns are described and quantified by measuring hormonal and neuroendocrine patterns and relating these to organ function in the short term. This includes an assessment of whether there are markers for the severity of stress that are better than conventional descriptors of the severity of a burn in predicting failing organ function. P-CgA after a major burn injury is an independent and better predictor of organ dysfunc...

    Bell's theorem proves the existence of entangled quantum states with no classical counterpart. An experimental violation of Bell's inequality demands simultaneously high fidelities in the preparation, manipulation and measurement of multipartite quantum entangled states, and provides a single-number benchmark for the performance of devices that use such states for quantum computing. We demonstrate a Bell/ Clauser-Horne-Shimony-Holt inequality violation with Bell signals up to 2.70(9), using the electron and the nuclear spins of a single phosphorus atom embedded in a silicon nanoelectronic device. Two-qubit state tomography reveals that our prepared states match the target maximally entangled Bell states with >96% fidelity. These experiments demonstrate complete control of the two-qubit Hilbert space of a phosphorus atom and highlight the important function of the nuclear qubit to expand the computational basis and maximize the readout fidelity.

  19. Lepton Flavor Violation in Flavored Gauge Mediation

    CERN Document Server

    Calibbi, Lorenzo; Ziegler, Robert

    2014-01-01

    We study the anatomy and phenomenology of Lepton Flavor Violation (LFV) in the context of Flavored Gauge Mediation (FGM). Within FGM, the messenger sector couples directly to the MSSM matter fields with couplings controlled by the same dynamics that explains the hierarchies in the SM Yukawas. Although the pattern of flavor violation depends on the particular underlying flavor model, FGM provides a built-in flavor suppression similar to wave function renormalization or SUSY Partial Compositeness. Moreover, in contrast to these models, there is an additional suppression of left-right (LR) flavor transitions by third-generation Yukawas that in particular provides an extra protection against flavor-blind phases. We exploit the consequences of this setup for lepton flavor phenomenology, assuming that the new couplings are controlled by simple U(1) flavor models that have been proposed to accommodate large neutrino mixing angles. Remarkably, it turns out that in the context of FGM these models can pass the impressi...

  20. Muon anomaly and dark parity violation.

    Science.gov (United States)

    Davoudiasl, Hooman; Lee, Hye-Sung; Marciano, William J

    2012-07-20

    The muon anomalous magnetic moment exhibits a 3.6σ discrepancy between experiment and theory. One explanation requires the existence of a light vector boson, Z(d) (the dark Z), with mass 10-500 MeV that couples weakly to the electromagnetic current through kinetic mixing. Support for such a solution also comes from astrophysics conjectures regarding the utility of a U(1)(d) gauge symmetry in the dark matter sector. In that scenario, we show that mass mixing between the Z(d) and ordinary Z boson introduces a new source of "dark" parity violation, which is potentially observable in atomic and polarized electron scattering experiments. Restrictive bounds on the mixing (m(Z(d))/m(Z))δ are found from existing atomic parity violation results, δ2expected to be reached, thereby complementing direct searches for the Z(d) boson.

    Minimal flavour violation in its strong or weak versions, based on U(3){sup 3} and U(2){sup 3}, respectively, allows suitable extensions of the standard model at the TeV scale to comply with current flavour constraints in the quark sector. Here we discuss considerations analogous to minimal flavour violation (MFV) in the context of SU(5)-unification, showing the new effects/constraints that arise both in the quark and in the lepton sector, where quantitative statements can be made controlled by the CKM matrix elements. The case of supersymmetry is examined in detail as a particularly motivated example. Third generation sleptons and neutralinos in the few hundred GeV range are shown to be compatible with current constraints. (orig.)

    We consider supersymmetric extensions of the standard model in which the usual $R$ or matter parity gets replaced by another $R$ or non-$R$ discrete symmetry that explains the observed longevity of the nucleon and solves the $\\mu$ problem of MSSM. In order to identify suitable symmetries, we develop a novel method of deriving the maximal $\\mathbb{Z}_{N}^{(R)}$ symmetry that satisfies a given set of constraints. We identify $R$ parity violating (RPV) and conserving models that are consistent with precision gauge unification and also comment on their compatibility with a unified gauge symmetry such as the Pati-Salam group. Finally, we provide a counter-example to the statement found in the recent literature that the lepton number violating RPV scenarios must have $\\mu$ term and the bilinear $\\kappa \\, L \\, H_u$ operator of comparable magnitude.

No evidence of CP violation is found and the imaginary part of the charged Higgs coupling, {l_brace}Im{r_brace}({Lambda}), in the Multi-Higgs-Doublet-Model is found to be at -0.284 < {l_brace}Im{r_brace}({Lambda}) < 0.200 at 90% Confidence Level.

    New sub-GeV vector bosons with couplings to muons but not electrons have been discussed in order to explain the muon's magnetic moment, the gap of high-energy neutrinos in IceCube or the proton radius puzzle. If such a light Z' not only violates lepton universality but also lepton flavor, as expected for example from the recent hint for $h\\to\\mu\\tau$ at CMS, the two-body decay mode $\\tau \\to \\mu Z'$ opens up and for $M_{Z'} < 2 m_\\mu$ gives better constraints than $\\tau\\to 3\\mu$ already with 20-year-old ARGUS limits.

  7. CP-violation in Compton scattering

    CERN Document Server

    Gorchtein, Mikhail

    2008-01-01

    I consider Compton scattering off the nucleon in the presence of $CP$ violation. I construct the Compton tensor which possesses these features and consider low energy expansion (LEX) of the corresponding amplitudes. It allows to separate out the Born contribution which only depends on the static properties of the nucleon, such as the electric charge, the mass, the magnetic moment, and the electric dipole moment (EDM). I introduce new structure constants, the $T$-odd nucleon polarizabilities which parametrize the unknown non-Born part. These constants describe the response of the $T$-violating content of the nucleon to the external quasistatic electromagnetic field. As an estimate, I provide a HBChPT calculation for these new polarizabilities and discuss the implications for the experiment.

    2000-01-01

    We propose a nuclear mechanism which can induce an atomic electric dipole moment (EDM). Parity and time reversal violating (P,T-odd) nuclear forces generate a mixed P,T-odd nuclear polarizability beta_{ik} (defined by an energy shift U = -beta_{ik} E_{i}H_{k}, E is electric field and H magnetic field). The interaction of atomic electrons with beta_{ik} produces an atomic EDM. We performed an analytical calculation of the P,T-odd nuclear polarizability and estimated the value for the induced atomic EDM. The measurements of atomic EDMs can provide information about P,T-odd nuclear forces and test models of CP-violation.

    2001-01-01

    The joint realm of quantum mechanics and the general-relativistic description of gravitation is becoming increasingly accessible to terrestrial experiments and observations. In this essay we study the emerging indications of the violation of equivalence principle (VEP). While the solar neutrino anomaly may find its natural explanation in a VEP, the statistically significant discrepancy observed in the gravitationally induced phases of neutron interferometry seems to be the first indication of a VEP. However, such a view would seem immediately challenged by the atomic interferometry results. The latter experiments see no indications of VEP, in apparent contradiction to the neutron interferometry results. Here we present arguments that support the view that these, and related torsion pendulum experiments, probe different aspects of gravity; and that current experimental techniques, when coupled to the solar-neutrino data, may be able to explore quantum mechanically induced violations of the equivalence principl...

    Parity violating electron nucleus scattering is a clean and powerful tool formeasuring the spatial distributions of neutrons in nuclei with unprecedentedaccuracy. Parity violation arises from the interference of electromagnetic andweak neutral amplitudes, and the $Z^0$ of the Standard Model couples primarilyto neutrons at low $Q^2$. The data can be interpreted with as much confidenceas electromagnetic scattering. After briefly reviewing the present theoreticaland experimental knowledge of neutron densities, we discuss possible parityviolation measurements, their theoretical interpretation, and applications. Theexperiments are feasible at existing facilities. We show that theoreticalcorrections are either small or well understood, which makes the interpretationclean. The quantitative relationship to atomic parity nonconservationobservables is examined, and we show that the electron scattering asymmetriescan be directly applied to atomic PNC because the observables haveapproximately the same dependence on nucle...

  13. Parity-Violation in Deep Inelastic Scattering

    International Nuclear Information System (INIS)

    The completion of the planned 12 GeV upgrade at Jefferson Lab will open a new avenue for precision studies of the high-x structure of the nucleon through parity-violation in deeply-inelastic scattering (PV-DIS). PV-DIS would be a clean technique for studying quark-level charge symmetry violation, probing higher-twist effects and for a measurement of the structure function ratio d/u at high x. In addition to these topics in hadronic physics, these measurements would also provide access to a linear combination of the poorly measured axial electron-quark weak couplings C2u and C2d, thus provide an important test of the electroweak Standard Model.

    2011-09-01

    Through our International Year of Astronomy outreach effort, we established a sustainable astronomy program and curriculum in the Northfield, Minnesota community. Carleton College offers monthly open houses at Goodsell Observatory and donated its recently "retire" observing equipment to local schools. While public evenings continue to be popular, the donated equipment was underutilized due to a lack of trained student observing assistants. With sponsorship from NASA's IYA Student Ambassador program, the sustainable astronomy project began in 2009 to generate greater interest in astronomy and train middle school and high school students as observing assistants. Carleton physics majors developed curricular materials and instituted regular outreach programs for grades 6-12. The Northfield High School Astronomy Club was created, and Carleton undergraduates taught high school students how to use telescopes and do CCD imaging. During the summer of 2009, Carleton students began the Young Astronomers Summer Experience (YASE) program for middle school students and offered a two-week, astronomy-rich observing and imaging experience at Goodsell Observatory. In concert with NASA's Summer of Innovation initiative, the YASE program was offered again in 2010 and engaged a new group of local middle school students in hands-on scientific experiments and observing opportunities. Members of the high school astronomy club now volunteer as observing assistants in the community and graduates of the YASE programs are eager to continue observing as members of a public service astronomy club when they enter the Northfield High School. These projects are training future scientists and will sustain the public's interest in astronomy long after the end of IYA 2009.

    Spectral hole burning is investigated in an optical medium in the presence of Doppler broadening and Kerr nonlinearity. The Kerr nonlinearity generates coherent hole burning in the absorption spectrum. The higher order Kerr nonlinearity enhances the typical lamb dip of the hole. Normal dispersion in the hole burning region while Steep anomalous dispersion between the two hole burning regions also enhances with higher order Kerr effect. A large phase shift creates large delay or advancement in the pulse propagation while no distortion is observed in the pulse. These results provide significant steps to improve optical memory, telecom devices, preservation of information and image quality. Supported by Higher Education Commission (HEC) of Pakistan

    Practice guidelines (PGs) are recommendations for diagnosis and treatment of diseases and injuries, and are designed to define optimal evaluation and management. The first PGs for burn care addressed the issues encountered in developed countries, lacking consideration for circumstances in resource-limited settings (RLS). Thus, the mission of the 2014-2016 committee established by the International Society for Burn Injury (ISBI) was to create PGs for burn care to improve the care of burn patients in both RLS and resource-abundant settings. An important component of this effort is to communicate a consensus opinion on recommendations for burn care for different aspects of burn management. An additional goal is to reduce costs by outlining effective and efficient recommendations for management of medical problems specific to burn care. These recommendations are supported by the best research evidence, as well as by expert opinion. Although our vision was the creation of clinical guidelines that could be applicable in RLS, the ISBI PGs for Burn Care have been written to address the needs of burn specialists everywhere in the world.

    Full Text Available Burns are known as one of the most common forms of injury with devastating consequences. Despite the discovery of several antiseptics, burn wound healing has still remained a challenge to modern medicine. Herbal products seem to possess moderate efficacy with no or less toxicity and are less expensive compared to synthetic drugs. Burn is a well-known disorder in Iranian Traditional Medicine (ITM. Iranian physicians have divided burns into various types based on the cause and recommended treatment for each type. According to ITM references, herbal therapy was the major treatment prescribed by Iranian physicians for burns. In the present study, seven ancient Iranian medical texts were screened for the herbs with burn healing effects along with their applied dosage forms. The medicinal herbs were listed and scored based on the frequency of their repetition. Moreover, the best scientific name that was suitable for each plant as well as surveying modern studies about their biological effects has been carried out. In our investigation eighteen plants with seven topical application categories have been obtained as the most frequent herbs for burn healing in ITM. Modern studies have revealed that these plants have shown some biological activities such as anti-inflammatory, antimicrobial and antioxidant effects which might establish the relationship between the mentioned activities and burn wound healing property. This list can provide a suitable resource for future researches in the field of burn treatment.

    Infectious consequences are still a major problem and leading cause of mortality in burn patients. Among others, aeromonads need special concern because they mimic pseudomonal infections; however, they have a more rapid progression with considerable mortality if undiagnosed promptly. Here, we present a major burn case extinguished with tap water pooled in a tank. With the possibility of aeromonal infection in mind, the patient underwent aggressive debridement with proper antibiotic medication, which resulted in a successful patient management. Aeromonads should always be kept in mind in burn cases that contacted with tanked water or soil after the burn. PMID:19692919

    We present a new mode of hydrogen burning on neutron stars (NSs) called diffusive nuclear burning (DNB). In DNB, the burning occurs in the exponentially suppressed tail of hydrogen that extends to the hotter regions of the envelope where protons are readily captured. Diffusive nuclear burning changes the compositional structure of the envelope on timescales $\\sim 10^{2-4} {\\rm yrs}$, much shorter than otherwise expected. This mechanism is applicable to the physics of young pulsars, millisecond radio pulsars (MSPs) and quiescent low mass X-ray binaries (LMXBs).

    The aims and purposes of this systematic review of the international literature are to discuss and clarify some considerations on Burning Mouth Syndrome (BMS). Over the last 40 years, many researchers have addressed this disease clinically or experimentally. Thus, the etiology and pathogenesis of BMS remain unclear. We analyzed the etiopathogenesis of Burning Mouth Syndrome and of the burning oral sensation and currently, we could not find a consensus on the diagnosis and classification of BMS. Further studies are required to better understand the pathogenesis of BMS, and a "Gold Standard" classification is required because not every burning sensation in the mouth is BMS. PMID:26863819

  2. Amniotic membrane for burn trauma

    International Nuclear Information System (INIS)

    Amniotic membranes are derived from human placentae at birth. They have two layers mainly the amniotic and the chorionic surfaces which are separated by a thin layer of connective tissues. The two layers are separated during procurement, the placenta and the chorionic side are discarded and the amnion membranes are then further processed. Amnion membranes are normally procured from placentae which are normally free of infections, i.e; the mothers are antenatally screened for sexually transmitted diseases or AlDs related diseases. Intrapartum the mother should not be having chorioamnionitis or jaundice. Sometimes the amniotic membranes are acquired from fresh elective caeserian sections. After processing, the amniotic membranes are packed in two layers of polypropylene and radiated with cobalt 60 at a dose of about 25 kGy. The amniotic membranes are clinically used to cover burn surfaces especially effective for superficial or partial thickness burns. The thin membranes adhered well to the trauma areas and peeled off automatically by the second week. No change of dressing were necessary during these times because of the close adherence, there were less chance of external contamination or infections of these wounds. Due to their flexibility they are very useful to cover difference contours of the human body for example the face, body, elbows or knees. However our experience revealed that amniotic membranes are not useful for third degree bums because the membranes dissolves by the enzymes present in the wounds

    We consider theories of flavored dark matter, in which the dark matter particle is part of a multiplet transforming nontrivially under the flavor group of the Standard Model in a manner consistent with the principle of Minimal Flavor Violation (MFV). MFV automatically leads to the stability of the lightest state for a large number of flavor multiplets. If neutral, this particle is an excellent dark matter candidate. Furthermore, MFV implies specific patterns of mass splittings among the flavo...

    In this work we explore a lepton flavor violation effect induced at one loop for a flavor structure in an extended minimal standard supersymmetric model, considering an ansatz for the trilinear term. In particular we find a finite expression which will show the impact of this phenomena in the $h\\to \\mu \\tau$ decay, produced by a mixing in the trilinear coupling of the soft supersymmetric Lagrangian.

    We review recent suggestions for testing through B decays the flavor structure of CP violation in the Standard Model. Relative signs of CP asymmetries in U-spin related processes can by themselves test the Kobayashi-Maskawa mechanism in a crude manner. Ratios of charge-averaged decay rates and certain CP asymmetries may constrain tightly the weak phases $\\gamma=\\phi_3$ and $\\alpha=\\phi_2$.

  6. Radiative violation of CP-symmetry

    International Nuclear Information System (INIS)

    The left-right quiral symmetry is not conserved by the Standard model. A subgroup of the standard gauge group (SU(2)L) breaks this symmetry in a explicit way. Moreover, the standard model, if there are theree or more matter generations, violates the CP discrete symmetry. This prediction has been experimentally demonstrated correct in the Kaon anti Kaon system. In this work some possible explanations to the CP violation parameter magnitude are researched. We have studied the variation of the Kobayashi-Maskawa matrix with the energy scale. To realize this work we have developed a general method to calculate the renormalization group equations of the Kobayashi-Maskawa matrix parameters. From these equations we could also calculate the renormalization group equation of the J parameter that characterizes the CP violation. This calculus has been applied in a concrete example: a typical supersymmetric model from superstring theories. This model can be seen like a natural extension of the supersymmetric standard model. This kind of models have a gauge group bigger that the standard one more particles and new terms of the Lagrangian. We have verified that such model provides us of a correct low energy fenomenology and, moreover other results, some particle spectrums have been developed. In the elaboration of this model some conditions, that the model has to respected to be compatible with the actual fenomenology, have been studied. The most interesting results of this thesis are the develop of a general method to calculate the renormalization group equations of the Kobayashi-Maskawa matrix parameters and the develop of a new mechanism of the radiative violation. This mechanism is related with the new terms of the Lagrangian. (Author)

    We present a study for a Supersymmetric field theory with Lorentz-Violation terms in 5D. We perform the analysis in the context of the Berger-Kostelecky model (BK), adding one compactified dimension that explicitly breaks the Lorentz invariance. We introduce terms that encode this breaking, and find non trivial restrictions over boundary conditions of fields that one needs to close the supersymmetric algebra.

    In this talk, I discuss implementation of minimal flavor violation (MFV) in seesaw models based on work appeared in arXiv:1401.2615, arXiv:1404.4436 and arXiv:1411.6612. Phenomenological implications on flavor-changing interactions related to leptons are studied by considering some effective dimension-six operators. We also comment on how one of the new effective operators can induce flavor-changing dilepton decays of the Higgs boson.

  9. Signals for CP Violation in Split Supersymmetry

    OpenAIRE

    Deshpande, N.G.; Jiang, J.

    2005-01-01

    Split supersymmetry is characterized by relatively light chargino and neutralino sector and very heavy sfermion sector. We study the consequence of CP violation in this scenario by evaluating two-loop contributions to electric dipole moments of fermions from Higgs-photon as well as $W$-$W$ diagrams. These contributions add coherently and produce electron and neutron electric dipole moments close to present bounds. We then explore Higgs production at a photon-photon collider, and consider the ...

    2002-01-01

    Recent solutions to the Einstein Field Equations involving negative energy densities, i.e., matter violating the weak-energy-condition, have been obtained, namely traversable wormholes, the Alcubierre warp drive and the Krasnikov tube. These solutions are related to superluminal travel, although locally the speed of light is not surpassed. It is difficult to define faster-than-light travel in generic space-times, and one can construct metrics which apparently allow superluminal travel, but ar...

  12. Dark matter and observable Lepton Flavour Violation

    OpenAIRE

    Heurtier, Lucien; Teresi, Daniele

    2016-01-01

    Seesaw models with leptonic symmetries allow right-handed (RH) neutrino masses at the electroweak scale, or even lower, at the same time having large Yukawa couplings with the Standard Model leptons, thus yielding observable effects at current or near-future lepton-flavour-violation (LFV) experiments. These models have been previously considered also in connection to low-scale leptogenesis, but the combination of observable LFV and successful leptogenesis has appeared to be difficult to achie...

    2004-01-01

    I briefly review CP violation in the B system, concentrating on B -> pi K decays. I discuss how to deal with electroweak-penguin contributions to these decays using flavour SU(3). With these, I show that the entire unitarity triangle can be extracted from measurements of B -> pi K decays. Finally, I examine the signals for new physics in these decays and the possibilities for measuring them.

    2011-01-01

    Minimum wage legislation is central in South African policy discourse, with both strong support and strong opposition. The validity of either position depends, however, on the effectiveness of minimum wage enforcement. Using detailed matching of occupational, sectoral and locational codes in the 2007 Labour Force Survey to the gazetted minimum wages, this paper presents, we believe for the first time, estimates of minimum wage violation in South Africa. Our results give considerable cause for...

  15. A new look at CP violation

    International Nuclear Information System (INIS)

    The CP violating (CPV) kaonic matrix elements ε', ImA0, and ImA2, are used to compute CPV observables in baryonic systems. The numerical results for the electric dipole moment and the difference between Λ and Λ- decay parameters are similar to other approaches that use quark operators. Relations between the neutron electric dipole moment, CPV pion-nucleon coupling constants, and Λ decay parameters are derived

    I consider Compton scattering off the nucleon in the presence of $CP$ violation. I construct the Compton tensor which possesses these features and consider low energy expansion (LEX) of the corresponding amplitudes. It allows to separate out the Born contribution which only depends on the static properties of the nucleon, such as the electric charge, the mass, the magnetic moment, and the electric dipole moment (EDM). I introduce new structure constants, the $T$-odd nucleon polarizabilities w...

  17. Comments on Charged Lepton Flavor Violation

    Energy Technology Data Exchange (ETDEWEB)

    2014-03-01

    Charged lepton flavor violation has been of interest since the muon (and subsequently, the tau lepton) was identified as a heavy version of the electron. CLFV continues to be pursued vigorously with the hope that its observation would reveal new information relating to the generation puzzle or about physics beyond the Standard Model. Theories abound which incorporate hypothetical CLFV at potentially observable levels although the mass scales and couplings are unknown, and innovative experiments continue to push the boundaries of sensitivity.

I also discuss related developments in parity-conserving scattering with transversely polarized electrons as a probe of two-photon processes. I conclude with a perspective on the future of the field.

  1. New Signatures of Flavor Violating Higgs Couplings

    CERN Document Server

    Buschmann, Malte; Liu, Jia; Wang, Xiao-Ping

    2016-01-01

    We explore several novel LHC signatures arising from quark or lepton flavor violating couplings in the Higgs sector, and we constrain such couplings using LHC data. Since the largest signals are possible in channels involving top quarks or tau leptons, we consider in particular the following flavor violating processes: (1) $pp \\to thh$ (top plus di-Higgs final state) arising from a dimension six coupling of up-type quarks to three insertions of the Higgs field. We develop a search strategy for this final state and demonstrate that detection is possible at the high luminosity LHC if flavor violating top--up--Higgs couplings are not too far below the current limit. (2) $pp \\to tH^0$, where $H^0$ is the heavy neutral CP-even Higgs boson in a two Higgs doublet model (2HDM). We consider the decay channels $H^0 \\to tu, WW, ZZ, hh$ and use existing LHC data to constrain the first three of them. For the fourth, we adapt our search for the $thh$ final state, and we demonstrate that in large regions of the parameter sp...

  2. Modeling Leggett-Garg-inequality violation

    Science.gov (United States)

    Moreira, Saulo V.; Keller, Arne; Coudreau, Thomas; Milman, Pérola

    2015-12-01

    The Leggett-Garg inequality is a widely used test of the "quantumness" of a system and involves correlations between measurements realized at different times. According to its widespread interpretation, a violation of the Leggett-Garg inequality disproves macroscopic realism and noninvasiveness. Nevertheless, recent results point out that macroscopic realism is a model-dependent notion and that one should always be able to attribute to invasiveness a violation of a Leggett-Garg inequality. This opens some natural questions: How do we provide such an attribution in a systematic way? How can apparent macroscopic realism violation be recast into a dimensional-independent invasiveness model? The present work answers these questions by introducing an operational model where the effects of invasiveness are controllable through a parameter associated with what is called the measurability of the physical system. Such a parameter leads to different generalized measurements that can be associated with the dimensionality of a system, to measurement errors, or to back action.

    Measurements of parity-violating longitudinal analyzing powers Az (normalized asymmetries) in polarized proton-proton scattering and in polarized neutron capture on the proton (n+p -> d+gamma) provide a unique window on the interplay between the weak and strong interactions between and within hadrons. Several new proton-proton parity violation experiments are presently either being performed or are being prepared for execution in the near future: at TRIUMF at 221 MeV and 450 MeV and at COSY (Forschungszentrum Jülich) in the multi-GeV range. A new measurement of the parity-violating gamma ray asymmetry with a ten-fold improvement in the accuracy over previous measurements is being developed at LANSCE. These experiments are intended to provide stringent constraints on the set of six effective weak meson-nucleon coupling constants, which characterize the weak interaction between hadrons in the energy domain where meson exchange models provide an appropriate description. The 221 MeV pp experiment is unique in th...

    Measurements of parity-violating longitudinal analyzing powers (normalized asymmetries) in polarized proton-proton scattering provide a unique window on the interplay between the weak and strong interactions between and within hadrons. Several new proton-proton parity violation experiments are presently either being performed or are being prepared for execution in the near future: at TRIUMF at 221 MeV and 450 MeV and at COSY (Kernforschungsanlage Jülich) at 230 MeV and near 1.3 GeV. These experiments are intended to provide stringent constraints on the set of six effective weak meson-nucleon coupling constants, which characterize the weak interaction between hadrons in the energy domain where meson exchange models provide an appropriate description. The 221 MeV is unique in that it selects a single transition amplitude (3P2-1D2) and consequently constrains the weak meson-nucleon coupling constant h_rho{pp}. The TRIUMF 221 MeV proton-proton parity violation experiment is described in some detail. A preliminar...

  5. Flavor Violation in the Scalar Sector

    Kopp, Joachim

    2016-01-01

    In many extensions of the Standard Model, the alignment in flavor space of the fermion mass matrices and the Yukawa coupling matrices can be broken. The physical scalar boson $h(125)$ could then have flavor changing couplings. In this talk, we summarize constraints on such couplings from rare decay searches, and we investigate current and future detection prospects at the LHC. We emphasize the importance of several yet unexplored final states: (i) anomalous single top + $h$ production in $p p \\to t h$, arising from $tuh$ couplings (but not from the more widely studied $tch$ couplings); (ii) $p p \\to t + (H^0 \\to h h)$ through $tuh$ couplings in the context of a Two Higgs Doublet Model (2HDM), perhaps the simplest model with flavor violation in the scalar sector; (iii) $p p \\to H^0 \\to \\tau\\mu$ in the 2HDM context. For all of these processes, we perform a detailed phenomenological studies. Finally, we comment on the possibility of flavor violation combined with CP violation, which may be interesting if the cur...

  6. Flavored dark matter beyond Minimal Flavor Violation

    International Nuclear Information System (INIS)

    We study the interplay of flavor and dark matter phenomenology for models of flavored dark matter interacting with quarks. We allow an arbitrary flavor structure in the coupling of dark matter with quarks. This coupling is assumed to be the only new source of violation of the Standard Model flavor symmetry extended by a U(3) χ associated with the dark matter. We call this ansatz Dark Minimal Flavor Violation (DMFV) and highlight its various implications, including an unbroken discrete symmetry that can stabilize the dark matter. As an illustration we study a Dirac fermionic dark matter χ which transforms as triplet under U(3) χ , and is a singlet under the Standard Model. The dark matter couples to right-handed down-type quarks via a colored scalar mediator with a coupling. We identify a number of ''flavor-safe'' scenarios for the structure of which are beyond Minimal Flavor Violation. Also, for dark matter and collider phenomenology we focus on the well-motivated case of b-flavored dark matter. Furthermore, the combined flavor and dark matter constraints on the parameter space of turn out to be interesting intersections of the individual ones. LHC constraints on simplified models of squarks and sbottoms can be adapted to our case, and monojet searches can be relevant if the spectrum is compressed

    LHCb has collected the world's largest sample of charmed hadrons. This sample is used to search for direct CP violation in the multibody prompt charm decays $D^0 -> \\pi^-\\pi^+\\pi^0$. The search is employing an unbinned model independent method known as the energy test. Using the data collected by LHCb at centre-of-mass energy of 8 TeV, the world's best sensitivity to CP violation in this decay is achieved. The data are found to be consistent with the hypothesis of CP symmetry with a p-value of $(2.6 \\pm 0.5)\\%$. New measurements of indirect CP violation in muon tagged $D^0$ decays to two-body CP even final states are presented. The time dependent CP asymmetries in the decay rates of the singly Cabibbo-suppressed decays $D^0->KK$ and $D^0->\\pi\\pi$ decays using the full LHCb run 1 data set are determined to be $A_{\\Gamma} (K^-K^+) = (-0.134 \\pm 0.077 ^{+0.026}_{-0.034})\\% ; A_{\\Gamma} (\\pi^-\\pi^+) = (-0.092 \\pm 0.145 ^{+0.025}_{-0.033})\\%$, and are compatible with the hypothesis of no indirect CPV and with ...

  8. Theoretical perspective for baryon number violation

    International Nuclear Information System (INIS)

    In this talk I describe the theoretical predictions for proton decay and other baryon number violating processes, emphasizing that there are many models and theories involving baryon number violation and that it is an experimental problem to distinguish between them. I first review the the theoretical predictions for the unification mass M/sub X/ and for the weak angle sin2theta/sub W/. It will be seen that the class of models involving an Su3 x SU2 x U1 invariant desert between M/sub W/ and M/sub X/ are strongly favored. I then turn to baryon number violation. The proton lifetime and branching ratio predictions for the SU5 and other 3-2-1 desert models are reviewed, with emphasis on distinguishing between models and on the implications of the small value of the QCD parameter lambda/sub anti MS/ that seems to be favored by the data. I then discuss the consequences of low energy supersymmetry for proton decay, nuclear effects, and models with low mass scales. Finally, I mention possible implications of the anomalously large flux of cosmic ray antiprotons that has recently been reported

    We point out that there is a unique parametrization of quark flavor mixing in which every angle is close to the Cabibbo angle θC≃13° with the CP-violating phase ϕq around 1°, implying that they might all be related to the strong hierarchy among quark masses. Applying the same parametrization to lepton flavor mixing, we find that all three mixing angles are comparably large (around π/4) and the Dirac CP-violating phase ϕl is also minimal as compared with its values in the other eight possible parametrizations. In this spirit, we propose a simple neutrino mixing ansatz which is equivalent to the tri-bimaximal flavor mixing pattern in the ϕl→0 limit and predicts sin θ13=1/√{2}sin(ϕl/2) for reactor antineutrino oscillations. Hence the Jarlskog invariant of leptonic CP violation Jl=(sin ϕl)/12 can reach a few percent if θ13 lies in the range 7°⩽θ13⩽10°.

  12. Deciding Where to Burn: Stakeholder Priorities for Prescribed Burning of a Fire-Dependent Ecosystem

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Multiagency partnerships increasingly work cooperatively to plan and implement fire management. The stakeholders that comprise such partnerships differ in their perceptions of the benefits and risks of fire use or nonuse. These differences inform how different stakeholders prioritize sites for burning, constrain prescribed burning, and how they rationalize these priorities and constraints. Using a survey of individuals involved in the planning and implementation of prescribed fire in the Onslow Bight region of North Carolina, we examined how the constraints and priorities for burning in the longleaf pine (Pinus palustris ecosystem differed among three stakeholder groups: prescribed burn practitioners from agencies, practitioners from private companies, and nonpractitioners. Stakeholder groups did not differ in their perceptions of constraints to burning, and development near potentially burned sites was the most important constraint identified. The top criteria used by stakeholders to decide where to burn were the time since a site was last burned, and a site's ecosystem health, with preference given to recently burned sites in good health. Differences among stakeholder groups almost always pertained to perceptions of the nonecological impacts of burning. Prescribed burning priorities of the two groups of practitioners, and particularly practitioners from private companies, tended to be most influenced by nonecological impacts, especially through deprioritization of sites that have not been burned recently or are in the wildland-urban interface (WUI. Our results highlight the difficulty of burning these sites, despite widespread laws in the southeast U.S. that limit liability of prescribed burn practitioners. To avoid ecosystem degradation on sites that are challenging to burn, particularly those in the WUI, conservation partnerships can facilitate demonstration projects involving public and private burn practitioners on those sites.

    Burn injury can be inflicted intentionally either by one person to another whenever one has the ability to physically control the other, or it can be self-inflicted. There is scant evidential basis for much that is written about and practiced in the evaluation and care of patients that have sustained intentional burn injuries. Yet this is an area in which medical personnel must necessarily be trained in both the therapeutic and forensic aspects of a complex problem. Failure to appreciate the complexity of medical and forensic interactions may have far reaching effects. A missed diagnosis can result in inappropriate medical care, on-going abuse and future fatality. Inept management can result on the one hand, in blame levelled inappropriately placing incomparable strain on family units and innocent parties, and on the other, allow abusers to continue unchecked. This is the first review on the subject in which lawyers and doctors collaborate to produce a holistic approach to this subject. In it we describe the legal considerations that medical staff must appreciate when approaching patients who may have suffered intentional burns. We analyse the various scenarios in which intentional burning can be found and challenge the clinical dogma with much of the management of paediatric inflicted burns has become imbued. We suggest a rational and balanced approach to all intentional burn injuries-especially when children are involved. In the light of current case law in which dogmatic medical evidence has been implicated in wrongful convictions for child abuse in the UK, it is imperative that medical professionals gather evidence carefully and completely and apply it with logic and impartiality. This paper will aid clinicians who may not be experienced in dealing with burn injuries, but find themselves in the position of seeing a burn acutely, to avoid common mistakes. PMID:15475134

  16. National programme for prevention of burn injuries

    Directory of Open Access Journals (Sweden)

    Gupta J

    2010-10-01

    Full Text Available The estimated annual burn incidence in India is approximately 6-7 million per year. The high incidence is attributed to illiteracy, poverty and low level safety consciousness in the population. The situation becomes further grim due to the absence of organized burn care at primary and secondary health care level. But the silver lining is that 90% of burn injuries are preventable. An initiative at national level is need of the hour to reduce incidence so as to galvanize the available resources for more effective and standardized treatment delivery. The National Programme for Prevention of Burn Injuries is the endeavor in this line. The goal of National programme for prevention of burn injuries (NPPBI would be to ensure prevention and capacity building of infrastructure and manpower at all levels of health care delivery system in order to reduce incidence, provide timely and adequate treatment to burn patients to reduce mortality, complications and provide effective rehabilitation to the survivors. Another objective of the programme will be to establish a central burn registry. The programme will be launched in the current Five Year Plan in Medical colleges and their adjoining district hospitals in few states. Subsequently, in the next five year plan it will be rolled out in all the medical colleges and districts hospitals of the country so that burn care is provided as close to the site of accident as possible and patients need not to travel to big cities for burn care. The programme would essentially have three components i.e. Preventive programme, Burn injury management programme and Burn injury rehabilitation programme.

  17. Actinide burning and waste disposal

    International Nuclear Information System (INIS)

    Here we review technical and economic features of a new proposal for a synergistic waste-management system involving reprocessing the spent fuel otherwise destined for a U.S. high-level waste repository and transmuting the recovered actinides in a fast reactor. The proposal would require a U.S. fuel reprocessing plant, capable of recovering and recycling all actinides, including neptunium americium, and curium, from LWR spent fuel, at recoveries of 99.9% to 99.999%. The recovered transuranics would fuel the annual introduction of 14 GWe of actinide-burning liquid-metal fast reactors (ALMRs), beginning in the period 2005 to 2012. The new ALMRs would be accompanied by pyrochemical reprocessing facilities to recover and recycle all actinides from discharged ALMR fuel. By the year 2045 all of the LWR spent fuel now destined f a geologic repository would be reprocessed. Costs of constructing and operating these new reprocessing and reactor facilities would be borne by U.S. industry, from the sale of electrical energy produced. The ALMR program expects that ALMRs that burn actinides from LWR spent fuel will be more economical power producers than LWRs as early as 2005 to 2012, so that they can be prudently selected by electric utility companies for new construction of nuclear power plants in that era. Some leaders of DOE and its contractors argue that recovering actinides from spent fuel waste and burning them in fast reactors would reduce the life of the remaining waste to about 200-300 years, instead of 00,000 years. The waste could then be stored above ground until it dies out. Some argue that no geologic repositories would be needed. The current view expressed within the ALMR program is that actinide recycle technology would not replace the need for a geologic repository, but that removing actinides from the waste for even the first repository would simplify design and licensing of that repository. A second geologic repository would not be needed. Waste now planned

    2015-01-01

    An argument by Banks, Susskind and Peskin (BSP), according to which violation of unitarity would violate either locality or energy-momentum conservation, is widely believed to be a strong argument against non-unitarity of Hawking radiation. We find that the whole BSP argument rests on the crucial assumption that the Hamiltonian is not highly degenerate, and point out that this assumption is wrong. Using Lindblad equation, we show that high degeneracy of the Hamiltonian allows local non-unitary evolution without violating energy-momentum conservation. Moreover, since energy-momentum is the source of gravity, we argue that energy-momentum is necessarily conserved for a large class of non-unitary systems with gravity. Finally, we explicitly calculate the Lindblad operators for non-unitary Hawking radiation and show that they conserve energy-momentum.

    Severe burn injury is associated with induction of the hepatic endoplasmic reticulum (ER) stress response. ER stress leads to activation of c-Jun N-terminal kinase (JNK), suppression of insulin receptor signaling via phosphorylation of insulin receptor substrate 1 and subsequent insulin resistance. Marked and sustained increases in catecholamines are prominent after a burn. Here, we show that administration of propranolol, a nonselective β1/2 adrenergic receptor antagonist, attenuates ER stress and JNK activation. Attenuation of ER stress by propranolol results in increased insulin sensitivity, as determined by activation of hepatic phosphatidylinositol 3-kinase and Akt. We conclude that catecholamine release is responsible for the ER stress response and impaired insulin receptor signaling after burn injury. PMID:22396018
