Estimation of power feedback parameters of the IBR-2M reactor by square wave reactivity

International Nuclear Information System (INIS)

Pepelyshev, Yu.N.; Popov, A.K.; Sumkhuu, D.

2016-01-01

Parameters of the IBR-2M reactor power feedback (PFB) are estimated based on the analysis of power transients caused by deliberate square wave reactivity when the pulsed reactor operates in the self-regulation mode. The PFB of the IBR-2M is described by three linear first-order differential equations. Two components of the PFB are responsible for the negative feedback and one, for the positive. The overall feedback is negative, i.e., it has a stabilizing effect for the operation of the reactor. The slowest negative component of the PFB is probably caused by heating of the fuel. Periodically repeated in the process of exploitation, estimation of the PFB parameters is one of the methods to ensure safety operation of the reactor. [ru

Infectious bovine rhinotracheitis (IBR)/infectious pustular vulvovaginitis (IPV) caused by Bovine alphaherpesvirus 1 (BoHV-1) is a significant disease in domestic and wild cattle. In June 2015, the Ministry of Agriculture, Food and Forestry in Italy approved a national surveillance plan to control and eradicate IBR in beef cattle breeds. The objective of this study was to evaluate the results of the first year of the IBR voluntary surveillance plan in Italy. The aim of the plan is to eradicate IBR in all bovines recorded in the National Herd Book for Italian beef cattle breeds over six years. Monetary incentives are used to encourage breeders to achieve the annual seroprevalence ranges stated in the plan. A Ministerial decree states that all bovines in breeding herds and aged older than 12 months should be serologically tested. Serum samples were tested for presence of the antibody to glycoprotein E of BoHV-1 using commercially available enzyme-linked immunosorbent assays. The national herd seroprevalence was 55.49% (95% confidence interval [CI] 52.01-58.92). Of 25,121 bovines tested for antibodies against BoHV-1, 8014 were positive. The seroprevalence in animals from autochthonous Italian cattle breeds was 31.89% (95% CI 31.31-32.47). Seroprevalence was highest in Podolica cattle (55.14%; 95% CI 54.07-56.21), lowest in Maremmana cattle (9.95%; 95% CI 7.99-12.31), and intermediate in Chianina (22.01%; 95% CI 21.03-23.01), Marchigiana (24.85%; 95% CI 23.52-26.23), and Romagnola (15.60%; 95% CI 14.62-16.64) cattle. These seroprevalence rates indicate a need for intervention to decrease the inevitable severe economic losses arising from BoHV-1 infection. Although some regions in Italy have a long history of combatting BoHV-1 infection, only the province of Bolzano has eradicated IBR. Copyright © 2018 Elsevier B.V. All rights reserved.

The article is dedicated to methods and results of experimental determination of cold neutron spectra from solid mesitylene at neutron moderator temperatures 10-50 K. Experiments were fulfilled at the DIN-2PI spectrometer of the IBR-2 reactor. The main goals of this work were to examine a system of constants for Monte Carlo calculation of cryogenic moderators of the IBR-2M reactor and to determine the temperature dependence of cold neutron intensity from the moderator. A reasonable agreement of experimental and calculation results for mesitylene at 20 K has been obtained. The cold neutron intensity at temperature of moderator 10 K is about 1.8 times higher than at T=50 K

Power noise spectrum classification in the problem of the IBR-2 reactor

International Nuclear Information System (INIS)

Bargel, M.; Kitowski, J.; Pepelyshev, Yu.N.

1988-01-01

The classification spectrum results of random fluctuations in the IBR-2 energy pulse are presented. The work is performed for the application of the obtained results to the reactor diagnostics and the study of its noise uncontrolled states. For classification of the spectra the method of pattern recognition based upon the ISODATA heuristic algorithm is used. It is shown that a set of noise uncontrolled reactor states, registered during the reactor operation period at power of 0.4-2 MVt with the first variant of moving reflector (1983-1986) is formed into 4(5) most typical states. Each of the states corresponds to the general conditions of the reactor core cooling and provides the normal work of the moving reflector. However, these states differ in coolant flow, power level and peculiarities of the moving reflector rotation regime. One type of anomal power noise, connected with some disorder in the moving reflctor work, is isolated. This work also presents the possibility of control over the state of moving reflectors according to the change in the amplitude of power oscillations at some frequences. The reactor noise classification results can be used as the data bank for the IBR-2 reactor diagnostic system

The intercalation of halogens in pitch-based fiber is studied as well as the stability of the resultant intercalation compounds. It is found that IBr intercalates P-100 to yield a high-sigma GIC with attractive stability properties. During ICl intercalation, the presence of O2 interferes with the reaction and necessitates a higher threshold pressure for intercalation.

Full Text Available Em meio às normas emitidas pelo International Accounting Standards Board (IASB e pelo Financial Accounting Standards Board (FASB, o presente estudo tem como objetivo analisar quais as principais normas em que as características que as conduzem a ser mais baseadas em princípios ou em regras são mais evidentes. Para atingir esse objetivo, este trabalho compara as principais normas emitidas pelo IASB e pelo FASB. Esses dois órgãos normatizadores foram escolhidos devido ao fato de que a literatura corrente considera que as normas emitidas pelo IASB e pelo FASB são, respectivamente, baseadas em princípios e em regras. Este trabalho, fruto de uma pesquisa documental e uma análise de conteúdo, revela que as normas do FASB, apesar de terem uma estrutura conceitual como base, possuem diversas especificidades que permitem que sejam consideradas como baseadas em regras. Dentre as normas estudadas, a característica do detalhamento presente nas normas de receitas emitidas pelo FASB e a presença de bright lines ou “limites” percentuais nas normas de relatórios por segmento, provisões e arrendamento mercantil conduzem a se classificar como baseadas em regras. Já as normas do IASB, por serem menos detalhadas e, praticamente, não possuírem bright lines, deixam espaço para maior julgamento profissional, ou seja, apresentam mais características de normas baseadas em princípios.

2013-01-01

The aim of the present research work was to optimise biogas production from cattle manure by adding crude glycerin from the biodiesel industry. For this purpose, 6%v/v crude glycerin (the optimum amount according to previous research) was added to ground manure and the mixture was sonicated to enhance biodegradability prior to anaerobic co-digestion at 55 °C. Two different reactors were used: continuously stirred (CSTR) and induced bed (IBR). The methanol and pure glycerin contents of the crude glycerin used in this study were 5.6% and 49.4% (w/w), respectively. The best results when operating in CSTR were obtained for an organic loading rate (OLR) of 5.4 kg COD/m(3) day, obtaining 53.2m(3) biogas/t wet waste and 80.7% COD removal. When operating in IBR, the best results were obtained for an OLR of 6.44 kg COD/m(3)day, obtaining 89.6% COD removal and a biogas production of 56.5m(3)/t wet waste. Copyright © 2012 Elsevier Ltd.

Full Text Available Em psiquiatria, observa-se grande variabilidade de práticas clínicas, muitas vezes desnecessária. Essas variações podem estar relacionadas à ausência de evidência científica confiável ou ao desconhecimento das evidências de boa qualidade disponíveis. A medicina baseada em evidências (MBE é uma combinação de estratégias que busca assegurar que o cuidado individual do paciente seja baseado na melhor informação disponível, a qual deve ser incorporada à prática clínica. Neste artigo, conceitos de MBE são discutidos com relação a aspectos e desafios no tratamento de pacientes com distimia, bulimia nervosa e esquizofrenia. A partir de resultados de três revisões sistemáticas recentemente publicadas, conclui-se que a prática de psiquiatria baseada em evidências acrescenta qualidade à prática psiquiátrica tradicional.The unnecessary variability often seen in the clinical practice can be related to both the absence of reliable evidence and unawareness of the existence of good quality evidence. Evidence-Based Medicine (EBM is a set of linked strategies designed to assist clinicians in keeping themselves up-to-date with the best available evidence. Such evidence must be incorporated into the clinical practice. EBM concepts are discussed here through common aspects and challenges doctors face when treating patients with dysthymia, bulimia nervosa, and schizophrenia. In the light of some results from three systematic reviews it is concluded that Evidence-Based Psychiatry strategies, rather than replacing the traditional ones, may be a valuable tool to improving quality in a good clinical practice.

The Amyris pilot-scale Integrated Biorefinery (IBR) leveraged Amyris synthetic biology and process technology experience to upgrade Amyris’s existing Emeryville, California pilot plant and fermentation labs to enable development of US-based production capabilities for renewable diesel fuel and alternative chemical products. These products were derived semi-synthetically from high-impact biomass feedstocks via microbial fermentation to the 15-carbon intermediate farnesene, with subsequent chemical finishing to farnesane. The Amyris IBR team tested and provided methods for production of diesel and alternative chemical products from sweet sorghum, and other high-impact lignocellulosic feedstocks, at pilot scale. This enabled robust techno-economic analysis (TEA), regulatory approvals, and a basis for full-scale manufacturing processes and facility design.

The operation performance of electrochemical energy conversion and storage systems such as supercapacitors and batteries depends on the processes occurring at the electrochemical interfaces, where charge separation and chemical reactions occur. Here, we report about the tests of the neutron reflectometry cells specially designed for operando studies of structural changes at the electrochemical interfaces between solid electrodes and liquid electrolytes. The cells are compatible with anhydrous electrolytes with organic solvents, which are employed today in all lithium ion batteries and most supercapacitors. The sensitivity of neutron reflectometry applied at the time-of-flight (TOF) reflectometer at the pulsed reactor IBR-2 is discussed regarding the effect of solid electrolyte interphase (SEI) formation on metal electrode surface.

Harbors are critical environments with strategic economic importance but with potential environmental impact: health assessment criteria are a key issue. An ecosystem health status approach was carried out in Portimão harbor as a case-study. Priority and specific chemical levels in sediments along with their bioavailability in mussels, bioassays and a wide array of biomarkers were integrated in a biomarker index (IBR index) and the overall data in a weight of evidence (WOE) model. Metals, PAHs, PCBs and HCB were not particularly high compared with sediment guidelines and standards for dredging. Bioavailability was evident for Cd, Cu and Zn. Biomarkers proved more sensitive namely changes of antioxidant responses, metallothioneins and vittellogenin-like proteins. IBR index indicated that site 4 was the most impacted area. Assessment of the health status by WOE approach highlighted the importance of integrating sediment chemistry, bioaccumulation, biomarkers and bioassays and revealed that despite some disturbance in the harbor area, there was also an impact of urban effluents from upstream.

2000-01-01

Experience in applying activation analysis with epithermal neutrons to environmental studies at the IBR-2 pulsed fast reactor in Dubna is reviewed. The principal units of the pneumatic system REGATA are described as well as the main present-day parameters of the irradiation channels. Examples from two challenging areas: analysis of airborne particulate matter and analysis of the biomonitors of atmospheric deposition, where the feasibility of ENAA related to non-nuclear multi-element techniques has been shown, are given. ENAA is presently being used in several projects carried out at FLNP JINR that involve the analysis of aerosol filters. For these studies, instrumental neutron activation analysis cannot feasibly be replaced by any non-nuclear analytical technique at the present state of art due to the fact that the total mass of the aerosol collected on filter samples is often rather small. This favours direct instrumental techniques rather than those depending on dissolving the sample prior to analysis. The dominant part of air pollution studies at FLNP JINR is based on the use of the moss biomonitoring technique resulting in a final product-maps of the atmospheric deposition of heavy metals, rare-earths, actinides (U and Th), etc., constructed by the GIS (geographical information system) technology

Results of experimental and computer modeling investigations of neutron spectra and fluxes obtained with cold and thermal moderators at the IBR-2 reactor (JINR, Dubna) are presented. The studies are done for small-angle neutron scattering (SANS) spectrometer YuMO (beamline number 4 of the IBR-2). The measurements of neutron spectra for two methane cold moderators are done for the standard configuration of the SANS instrument. The data from both moderators under different conditions of their operation are compared. The ratio of experimentally determined neutron fluxes of cold and thermal moderators at different wavelength is shown. Monte Carlo simulations are done to determine spectra for cold methane and thermal moderators. The results of the calculations of the ratio of neutron fluxes of cold and thermal moderators at different wavelength are demonstrated. In addition, the absorption of neutrons in the air gaps on the way from the moderator to the investigated sample is presented. SANS with the protein apoferritin was done in the case of cold methane as well as a thermal moderator and the data were compared. The perspectives for the use of the cold moderator for a SANS spectrometer at the IBR-2 are discussed. The advantages of the YuMO spectrometer with the thermal moderator with respect to the tested cold moderator are shown

Dynamic response characteristics of dual flow-path integrally bladed rotors

Science.gov (United States)

Beck, Joseph A.; Brown, Jeffrey M.; Scott-Emuakpor, Onome E.; Cross, Charles J.; Slater, Joseph C.

2015-02-01

New turbine engine designs requiring secondary flow compression often look to dual flow-path integrally bladed rotors (DFIBRs) since these stages have the ability to perform work on the secondary, or bypassed, flow-field. While analogous to traditional integrally bladed rotor stages, DFIBR designs have many differences that result in unique dynamic response characteristics that must be understood to avoid fatigue. This work investigates these characteristics using reduced-order models (ROMs) that incorporate mistuning through perturbations to blade frequencies. This work provides an alternative to computationally intensive geometric-mistuning approaches for DFIBRs by utilizing tuned blade mode reductions and substructure coupling in cyclic coordinates. Free and forced response results are compared to full finite element model (FEM) solutions to determine if any errors are related to the reduced-order model formulation reduction methods. It is shown that DFIBRs have many more frequency veering regions than their single flow-path integrally blade rotor (IBR) counterparts. Modal families are shown to transition between system, inner-blade, and outer-blade motion. Furthermore, findings illustrate that while mode localization of traditional IBRs is limited to a single or small subset of blades, DFIBRs can have modal energy localized to either an inner- or outer-blade set resulting in many blades responding above tuned levels. Lastly, ROM forced response predictions compare well to full FEM predictions for the two test cases shown.

2007-01-01

For calculation of power transients in the IBR-2 reactor a special mathematical model of dynamics taking into account the discontinuous jump of reactivity by an automatic controller with the step motor is created. In the model the nonlinear dependence of the energy of power pulse on the reactivity and the influence of warming up of the reactor on the reactivity by means of introduction of a nonlinear feedback 'power-pulse energy - reactivity' are taken into account. With the help of the model the transients of relative deviation of power-pulse energy are calculated at various (random, mixed and regular) reactivity disturbances at the reactor mean power 1.475 MW. It is shown that to improve the quality of processes the choice of such regular values of parameters of the automatic controller is expedient, at which the least effect of smoothing of a signal acting on an automatic controller and the least speed of an automatic controller are provided, and the reduction of efficiency of one step of the automatic controller and introduction of a five-percent dead space are also expedient

The development of network infrastructure in Dubna creates conditions for the remote supervision/control of experiment at the IBR-2M reactor beyond the JINR local network. The opportunity of observing an experiment from outside makes it possible to respond to errors or unforeseen, to save the reactor time. The principles of organization and peculiarities of implementation of the WebSonix system consisting of the central web-site and communication facilities for spectrometers are considered in the paper. The system allows one to reflect the actual condition of all the components of the instrument, survey log files, visualize the accumulated spectra and to control the experimental procedure on the instruments controlled by the software complex Sonix+ (OS Windows XP). The system is an independent instrument, it is easy to extend or change and easy to adapt to the instrument data specifics. The system is implemented using the PHP and Python scripts. The OS GNU/Linux Debian and web-server Apache 2 are installed on the web-site computer

The irradiation facility at the beam line no.3 of the IBR-2 reactor of the Frank Laboratory for Neutron Physics is described. The facility is aimed at irradiation studies of various objects with area up to 800 cm$^2$ both at cryogenic and ambient temperatures. The energy spectra of neutrons are reconstructed by the method of threshold detector activation. The neutron fluence and $\\gamma$ dose rates are measured by means of alanine and thermoluminescent dosimeters. The boron carbide and lead filters or $(n/\\gamma)$ converter provide beams of different ratio of doses induced by neutrons and photons. For the lead filter, the flux of fast neutrons with energy more than 0.1 MeV is $1.4 \\cdot 10^{10}$ \\fln and the neutron dose is about 96\\% of the total radiation dose. For the $(n/\\gamma)$ converter, the $\\gamma$ dose rate is $\\sim$500 Gy h$^{-1}$ which is about 85\\% of the total dose.

Experimental investigations of stochastic fluctuations of pulse energy of the IBR-2M reactor have been carried out which allowed us to obtain some of the parameters of the reactor kinetics. At different levels of average power a sequence of values of pulse energy was recorded with the calculation of the distribution parameters. An ionization chamber with boron installed near the active zone was used as a neutron detector. The research results allowed us to estimate the average lifetime of prompt neutrons τ = (6.53±0.2)·10 -8 s, absolute power of the reactor and intensity of the source of spontaneous neutrons S sp ≤(6.72±0.12)·10 6 s -1 . It was shown that the experimental results are close to the calculated ones

The Second International Workshop 'SANS-YuMO User Meeting at the Start-up of Scientific Experiments on the IBR-2M Reactor', devoted to the 75th anniversary of the birth of Professor Yu M Ostanevich (1936-1992), an outstanding neutron physicist and the founder of small-angle neutron scattering (field, group, and instrument) at JINR FLNPh, was held on 27-30 May at the Frank Laboratory of Neutron Physics. The first Workshop was held in October 2006. Research groups from different neutron centers, universities and research institutes across Europe presented more than 35 oral and poster presentations describing scientific and methodological results. Most of them were obtained with the help of the YuMO instrument before the IBR-2 shutdown in 2006. For the last four years the IBR-2 reactor has been shut down for refurbishment. At the end of 2010 the physical launch of the IBR-2M reactor was finally realized. Nowadays the small-angle neutron scattering (SANS) technique is applied to a wide range of scientific problems in condensed matter, soft condensed matter, biology and nanotechnology, and despite the fact that there are currently over 30 SANS instruments in operation worldwide at both reactor and spallation sources, the demand for beam-time is considerably higher than the time available. It must be remembered, however, that as the first SANS machine on a steady-state reactor was constructed at the Institute Laue Langevin, Grenoble, the first SANS instrument on a 'white' neutron pulsed beam was accomplished at the Joint Institute for Nuclear Research at the IBR-30 reactor, beamline N5. During the meeting Yu M Ostanevich's determinative and crucial contribution to the construction of spectrometers at the IBR-2 high-pulsed reactor was presented, as well as his contribution to the development of the time-of-flight (TOF) small-angle scattering technique, and a selection of other scientific areas. His leadership and outstanding scientific achievements in applications of the

The automation system for measurement of induced activity of gamma-ray spectra for multi-element high-volume neutron activation analysis (NAA) was designed, developed and implemented at the IBR-2 reactor. The system consists of three devices of automatic sample changers for three Canberra HPGe detector-based gamma spectrometry systems. Each sample changer consists of two-axis linear positioning module M202A by DriveSet (DriveSet.de) company and disk with 45 slots for containers with samples. Control of automatic sample changer is performed by the Xemo S360U controller by Systec (systec.de) company. Positioning accuracy can reach 0.1 mm. Special software performs automatic changing of samples and measurement of gamma spectra at constant interaction with the NAA database. The system is unique and can be recommended for other laboratories as one of the possible ways of the NAA integrated automation

Neutron diffraction is widely used for investigations of residual and applied stresses in bulk materials and components. The most important factor in these investigations is the high penetration depth of neutrons (up to 2 cm for steel). At the IBR-2 pulsed reactor in Dubna the Fourier stress diffractometer (FSD) has been constructed to optimize the internal stress measurements. The FSD design satisfies the requirements of high luminosity, high resolution and specific sample environment. The collimator system guarantees a minimum gauge volume of 2x2x2 mm. A mechanical testing machine allows in-situ tension or compression measurements up to a load of 20 kN and sample temperatures up to 800 deg C. In the paper the current status of FSD is reported and potentialities are demonstrated with several examples of investigations performed

Full Text Available This paper is concerned with sketching future directions for corpus-based dialectology. We advocate a holistic approach to the study of geographically conditioned linguistic variability, and we present a suitable methodology, 'corpusbased dialectometry', in exactly this spirit. Specifically, we argue that in order to live up to the potential of the corpus-based method, practitioners need to (i abandon their exclusive focus on individual linguistic features in favor of the study of feature aggregates, (ii draw on computationally advanced multivariate analysis techniques (such as multidimensional scaling, cluster analysis, and principal component analysis, and (iii aid interpretation of empirical results by marshalling state-of-the-art data visualization techniques. To exemplify this line of analysis, we present a case study which explores joint frequency variability of 57 morphosyntax features in 34 dialects all over Great Britain.Este artigo debruça-se sobre o esboço propositivo de futuras direções para a dialetologia baseada em corpus. Defendemos uma abordagem holística para o estudo da variabilidade linguística geograficamente condicionada, e apresentamos uma metodologia adequada para tal - a dialetometria baseada em corpus. Mais especificamente, defendemos que para que se obtenham todos os resultados esperados da metodologia de corpus, pesquisadores devem: (i abandonar seu foco exclusivo em traços linguísticos individuais em favor do estudo dos agregados de traços, (ii amparar-se em métodos computacionais avançados de técnicas de análise multivariada (tais como escalagem multidimensional, análise de clusters, e análise de componente principal, e (iii auxiliar a interpretação de resultados empíricos através da utilização do estado da arte em técnicas de visualização. A fim de exemplificarmos essa linha de análise, apresentamos um estudo de caso que explora a variabilidade da frequência agregada de 57 tra

Organic pollution is a serious environmental problem in coastal areas and it is important to establish quantitative methods for monitoring this pollution. This study screened a series of sensitive biomarkers to construct an integrated biomarker response (IBR) index using Mytilus edulis. Mussels were exposed to the polycyclic aromatic hydrocarbon anthracene under controlled laboratory conditions and the activities of components of the glutathione antioxidant system, and the concentrations of oxidative-damage markers, were measured in the gills and digestive glands. Anthracene exposure resulted in increased levels of malondialdehyde (MDA) and superoxide radicals (O 2 • ), indicating that oxidative damage had occurred. Correspondingly, anthracene exposure induced increased activities of glutathione S-transferase (GST), glutathione peroxidase (GPx) and reduced glutathione (GSH) in digestive glands, and GPx and glutathione reductase (GR) in gills, consistent with stimulation of the antioxidant system. A field experiment was set up, in which mussels from a relatively clean area were transplanted to a contaminated site. One month later, the activities of GST, GPx and GR had increased in several tissues, particularly in the digestive glands. Based on the laboratory experiment, an IBR, which showed a positive relationship with anthracene exposure, was constructed. The IBR is suggested to be a potentially useful tool for assessing anthracene pollution.

The biological effects of a coastal process water (PW) discharge on native and caged mussels (Mytilus edulis) were assessed. Chemical analyses of mussel tissues and semi permeable membrane devices, along with a suite of biomarkers of different levels of biological complexity were measured. These were lysosomal membrane stability in haemocytes and digestive cells; micronuclei formation in haemocytes; changes in cell-type composition in the digestive gland epithelium; integrity of digestive gland tissue; peroxisome proliferation; and oxidative stress. Additionally the Integrative Biological Response (IBR/n) index was calculated. This integrative biomarker approach distinguished mussels, both native and caged, exhibiting different stress conditions not identified from the contaminant exposure. Mussels exhibiting higher stress responses were found with increased proximity to the PW discharge outlet. However, the biological effects reported could not be entirely attributed to the PW discharge based on the chemicals measured, but were likely due to either other chemicals in the discharge that were not measured, the general impact of the processing plant and or other activities in the local vicinity. - Highlights: Black-Right-Pointing-Pointer Good agreement between biomarkers for the different mussel groups. Black-Right-Pointing-Pointer IBR/n was able to differentiate between exposed and reference mussels. Black-Right-Pointing-Pointer Mussels closest to the PW outlet were in poorest health. Black-Right-Pointing-Pointer Chemical concentrations were low or undetected in all SPMD and mussel samples. Black-Right-Pointing-Pointer Biomarker responses could not be entirely attributed to the PW discharge.

Full Text Available Resumo Tradicionalmente, a escolha pelo tipo de intervenção psicoterápica para diferentes quadros clínicos depende fundamentalmente da experiência profissional do terapeuta e de sua predileção por determinadas estratégias clínicas. Todavia, esse cenário tem se modificado no contexto da prática baseada em evidências. Apesar do extenso e acalorado debate na literatura internacional da Psicologia nos últimos anos, o tema da prática baseada em evidências tem sido pouco discutido na Psicologia brasileira. Em vista disso, este artigo tem por objetivo apresentar o paradigma de prática baseada em evidências em Psicologia sob uma perspectiva histórica, enfatizando o embate entre os diferentes posicionamentos sobre o assunto e os esforços da American Psychological Association em elaborar um modelo representativo das diversas perspectivas teóricas, metodológicas, conceituais e práticas com o intuito de preencher a lacuna entre ciência e prática ainda existente na Psicologia Clínica. Espera-se que este artigo possa contribuir para uma maior participação da Psicologia brasileira nesse movimento.

Controllers SMC-32 and SMC-32-CAN as elements of control systems of executive mechanisms of the IBR-2 spectrometers are submitted. The controllers provide management of executive mechanisms of spectrometers on the consecutive communication line RS232, RS422 (SMC-32, SMC-32-CAN), and on the local network CAN (SMC-32-CAN). The control systems of the executive mechanisms are easily modernized due to connection of additional elements of the local network CAN. Dynamic characteristics of the spectrometers' executive mechanisms are essentially improved. For example, it has been possible to increase the rotation frequency of the step motor DSHI-200 up to 10000 pps. (author)

First experience with the new solid methane moderator at the IBR-2 reactor

2001-01-01

In the 1999 Fall the solid methane moderator (CM) has been installed and tested at full power at the IBR-2 pulsed reactor. Its main features are a beryllium reflector and a light water premoderator. Radiation load on the methane was three times as much as that of IPNS facility, namely, 0.1 W/g. Effects of temperature, operation time, concentration of a hydrogen scavenger, and annealing procedure on both neutron and service performances were studied. Maximum operation time of a newly loaded portion of methane was 4 days. In this time around 30% of methane is transformed into hydrogen, ethane, and high molecular hydrocarbons, and yet no deterioration in cold neutron intensity was detected. Among new knowledge, the most important are two facts observed: two-fold decrease in hydrogen formation rate when methane is poisoned with 2.5% to 5% of ethylene, and low formation rate of solid, inremovable products of radiolysis - (1.5/3)10 -7 g/J, which means that after 10 years of operation the methane chamber will be filled with only 100 g of residue. Gain of factor 20 in cold neutron flux was obtained as compared to the routine grooved light water moderator. Presently, it is the highest among the intense pulsed neutron sources. (author)

Background Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV) is a significant disease among domestic and wild cattle. The BHV-1 infection was first detected in Finland in 1970; presumably it was imported in 1968. The infection reappeared in the large-scale bulk-tank milk surveillances which started in 1990, and was eradicated in 1994. Our aim is to describe the epidemiology of this infection in Finland, and its eradication. Materials and methods The official sources of pertinent information, the legal basis for the disease control and the serological methods for the detection of the infection are described. Results and conclusion Ten AI bulls were found to be seropositive in 1970–1971. The total number of herds with BHV-1 antibody positive animals in the large-scale surveillance in 1990 and subsequent epidemiological investigations in 1991 was five, and the total number of seropositive animals was 90. The five herds formed three epidemiological units; semen of at least one bull seropositive in 1971 had been used in each unit. This remained the only plausible route of infection in each of the three units. Using the 'test and slaughter' approach and total stamping out in one herd the infection was eradicated in 1994.

Full Text Available O objetivo deste estudo foi avaliar a adesão à terapia antirretroviral (TARV, identificando possibilidades de intervenções embasadas no modelo de atenção às condições crônicas. MÉTODOS: Estudo observacional, quantitativo, transversal, desenvolvido com 215 pessoas com HIV/ AIDS em uso de antirretrovirais, entre março e junho de 2012, em Fortaleza, Ceará. De um questionário específico para avaliar a adesão utilizaram-se nove quesitos para discussão à luz do Modelo de Atenção às Condições Crônicas (MACC. RESULTADOS: 35,4% das pessoas estudadas deixaram de aderir ao tratamento pelo menos alguma vez, por se sentirem melhor/pior, ou tristes/deprimidas. Sob a luz do MACC, foram identificadas lacunas, como necessidade de mais intervenção profissional, evidenciando possibilidades de aplicar novas estratégias, como ações para o autocuidado, entrevista motivacional, grupo operativo, e outras. CONCLUSÃO: Constatou-se que há um percentual significativo de não adesão à TARV, cujas intervenções ainda são incipientes, e que ações baseadas no MACC podem favorecer uma assistência totalitária aos pacientes com HIV/AIDS.

Full Text Available A aprendizagem baseada em problema (Problem-Based Learning - PBL é uma teoria de aprendizagem que enfatiza a colaboração e o trabalho em grupo para resolução de um problema. No entanto, um problema que ocorre com freqüência no processo de aplicação da PBL é a presença de conversações fora do contexto, que é uma situação onde os estudantes perdem o foco das discussões do problema e passam a discutir outros assuntos. Outro aspecto importante é com relação ao processo de formação de grupos na PBL. Pode ser difícil para o facilitador alocar estudantes aos grupos a distância, uma vez que a ausência de um contato presencial dificulta o conhecimento de certas características importantes do perfil dos estudantes envolvidos no processo. Outro aspecto a ser considerado é a ausência de padronização dos conceitos relacionados à PBL, pois isto dificulta a compreensão comum e compartilhada sobre este domínio. Desta forma, este trabalho apresenta um sistema multiagente de apoio à PBL, com o objetivo de detectar e corrigir problemas inerentes à implantação desta teoria de aprendizagem. Para solucionar o problema de padronização dos conceitos relacionados à PBL, é proposta uma ontologia que preenche requisitos de abstração e significação dos conceitos relacionados ao domínio.

1997-01-01

The excitation cross sections of long-living isomers of 107m,109m Ag nuclei were measured for the fast neutron inelastic scattering reactions at the Ibr-2 reactor of JINR (Dubna) by means of a comparison with the yield of the 103m Rh isomer. The excitation cross sections of the latter are known for analogous reactions in the wide energy range. The measured cross sections are the following: σ( 107m Ag) 204 ± 18 mb, σ( 109m Ag) = 262 ± 26 mb. These values are essentially lower than the excitation cross section of the 103m Rh isomer. The analysis of the data on level structures and transitions between these levels for rhodium and silver nuclei together with the data on γ-spectra created in the reactions (n, n ' γ) shows that the essential difference between excitation cross sections of Rh and Ag isomers can be explained by different populations of corresponding levels

In Brazil, the Regulatory Standard n. 13 (NR 13) establishes requirements for the inspection of boilers and pressure vessels which has main objective of preventing accidents with these types of equipment. Additionally, it has the Risk-Based Inspection (RBI) technique as an effective way to manage the mechanical integrity of various types of static mechanical equipment by through an inspection planning based on the risk factor. In this study, it is being proposed to include the RBI technique, in the NR 13, for the planning and definition of periods for the safety inspection of boilers and pressure vessels in order to promote an increase in the operational safety in process industries in Brazil. In this study it was carried out a critical analysis of NR 13 and RBI, and beyond that a bibliographic research of various international documents that relate the operational safety of pressurized equipment with the inspection activity, and the acceptability of RBI by governments, agencies and organizations around the world. It is considered that the inclusion and formal acceptance of RBI technique in the NR 13 must be accompanied by a rigorous control to avoid the 'trivialization' of its use and ensure the implementation rational, efficient and reliable. Finally, it was developed and suggested basic elements and minimum requirements to be inserted in the NR 13, to be attended, in order mandatory, by the companies that choose the implementation and use of the RBI technique as a tool for the planning of safety inspection of boilers and pressure vessels. It is concluded that the formal acceptance of the RBI technique in the NR 13 could aggregate much value to this standard, with regard to the prevention of accidents involving boilers or pressure vessels, and provide a technological jump to the companies that make use of RBI technique in Brazil.

Full Text Available Na atualidade existe uma demanda mundial por práticas na saúde baseadas em evidências em diversas especialidades envolvidas nos cuidados da saúde e sua promoção. A prática da psicologia baseada em evidências (PPBE integra a melhor evidência de pesquisa disponível, a expertise clínica, as preferências e características do cliente na tomada de decisão ao nível clinico e também na orientação de políticas públicas na saúde mental. Esse artigo discute os aspectos conceituais da PPBE, os níveis de evidência para a tomada de decisão, mitos e resistência a PPBE. Atualmente ainda existem muitas fontes de incompreensões e mitos acerca da PPBE, as quais constituem fontes de resistência para sua incorporação à prática clínica. Parte-se do princípio que entender os entraves à aceitação da PPBE é crucial não apenas para a construção de contra-argumentos, mas para auxiliar no processo de construção do conhecimento e da difusão de informações cientificas que possam orientar o cuidado oferecido aos indivíduos de forma efetiva e ética.

Organic and metal contaminants and biological effects were investigated in flounder, mussels, and sediments in the southern Baltic Sea coastal area in order to assess environmental quality status in that area. Four sites were selected, including two within the Gulf of Gdańsk (GoG). In biota and sediment at each site, DDTs dominated over PCBs and PBDEs were the least abundant among organic contaminants. Their concentrations decreased progressively outward from GoG. Among metal contaminants, the levels of Hg, Pb, and Cd were elevated in GoG. Biomarkers in flounder, EROD activity and DNA SB, showed moderate positive correlations with organic and metal contaminants. In flounder, the integrated biomarker index (IBR/n) presented a spatial trend coherent with chemical pollution index (CPI), but there was no clear spatial correspondence between IBR/n and CPI in mussels nor between sediment toxicity index (STI) and sediment CPI. The integrated assessment of contaminant and biological effect data against available assessment criteria indicated that in biota, the contaminant assessment thresholds were most often exceeded by CB-118, heptachlor, PBDE, and Hg (in the GoG sediments by p,p'-DDT, Hg and Cd), while of the biological determinants, the threshold was breeched by AChE activity in mussels in GoG. Applying the ICES/OSPAR traffic-light approach showed that of the 50 parameters assessed at each site, there were 18% of determinants in the red color category in the two GoG sites and 8% of determinants in the two sites outside GoG, which indicated that none of the four investigated sites attained good environmental status (GES).

Integrating financial theory and methods in electricity resource planning

Energy Technology Data Exchange (ETDEWEB)

Felder, F.A. [Economics Resource Group, Cambridge, MA (United States)

1996-02-01

Decision makers throughout the world are introducing risk and market forces in the electric power industry to lower costs and improve services. Incentive based regulation (IBR), which replaces cost of service ratemaking with an approach that divorces costs from revenues, exposes the utility to the risk of profits or losses depending on their performance. Regulators also are allowing for competition within the industry, most notably in the wholesale market and possibly in the retail market. Two financial approaches that incorporate risk in resource planning are evaluated: risk adjusted discount rates (RADR) and options theory (OT). These two complementary approaches are an improvement over the standard present value revenue requirement (PVRR). However, each method has some important limitations. By correctly using RADR and OT and understanding their limitations, decision makers can improve their ability to value risk properly in power plant projects and integrated resource plans. (Author)

The cross sections for the excitation of long-lived isomers of 107,109 Ag nuclei are measured in the inelastic scattering of fast neutrons from the IBR-2 reactor of JINR (Dubna). The measurements are performed by means of comparison with the yield of the 103m Rh isomer, for which the excitation cross sections are known over a wide energy range for similar reactions induced by monochromatic neutrons. The measured cross sections proved to be σ( 107m Ag)=204±18 mb and σ( 109m Ag)=262±26 mb. These values are significantly smaller than the cross section for the excitation of the 103m Rh isomer. An analysis employing information about the arrangement of energy levels in Rh and Ag and about transitions between these levels, as well as data on the spectra of γ rays emitted in (n,n'γ) reactions, reveals that the distinction between the cross sections for the excitation of Rh and Ag isomers can be explained by the difference in the population of corresponding levels of Rh and Ag nuclei

Human activities have altered estuarine environments leading to increased presence of different pollutants including metals. Although the implementation of new environmental policies has caused a considerable decrease in trace metal concentrations in estuaries around the Bay of Biscay, some elements such as copper (Cu) and silver (Ag) are still present in relatively high concentrations. Oysters have been widely used in environmental biomonitoring programs as sentinel organisms. Oysters Crassostrea gigas from an uncontaminated estuary were exposed to sublethal, environmentally relevant concentrations of Cu (2000 ng Cu/L) and Ag (500 ng Ag/L) during 14 days in brackish water (S = 18). A battery of cell and tissue level (exposure) biomarkers at different levels of biological complexity was applied and integrated into the Integrative Biological Response (IBR) index including: metallothionein contents, intralysosomal metal accumulation, digestive gland atrophy and digestive gland tissue integrity. Condition Index (CI) was incorporated into the IBR index as a complementary parameter that reflects the general physiological condition of oysters (organism level). Results indicated an increase in intralysosomal metal accumulation after 7 and 14 days of exposure to Ag together with an increase in the digestive epithelium atrophy and lipofuscin content after 7 days of exposure to Ag. The responses detected with the aid of biomarkers integrated in the IBR index showed higher toxicity in oysters exposed to Ag, inducing the clear onset of detoxification processes which also occurred, to a lower extent, in Cu-exposed oysters.

Dissociative multiple photoionization of the bromine, the iodine monobromide, and the iodine molecules in the Br(3d,3p,3s) and I(4d,4p,4s,3d,3p) inner-shell regions has been studied by using time-of-flight (TOF) mass spectrometry coupled to synchrotron radiation in the ranges of 90∼978 eV for Br 2 , 60∼133 eV for IBr, and 86∼998 eV for I 2 . Total photoion and photoion-photoion coincidence (PIPICO) yields have been recorded as functions of the photon energy. Here, giant shape resonances have been observed beyond the thresholds of the inner-shells owing to the Br(3d 10 )→Br(3d 9 -f), I(4d 10 )→I(4d 9 -f), and I(3d 10 )→I(3d 9 -f) transitions. The dissociation processes of the multiply charged parent ions have also been evaluated from variations of photoelectron-photoion coincidence (PEPICO) and PIPICO spectra with the photon energy. From each Br(3p 3/2 ) (189.9 eV) and I(4p 3/2 ) threshold (129.9 eV), quintuple ionization of the molecules begins to play important roles in the photoionization, subsequently yielding ion pairs of X 3+ -X 2+ (X=Br, I). From the I(3d 5/2 ) threshold (627.3 eV), loss of six electrons from iodine molecule additionally begins to play a minor role in the multiple photoionization, giving rise to the formation of ion pairs of either I 3+ -I 3+ or I 4+ -I 2+ . A direct comparison of the strengths and the ranges of the I(4d) and Br(3d) giant resonances was successfully made from dissociative photoionization of IBr. Over the entire energy range examined, 60< E<133 eV, biased charge spread relevant to the specific core-hole states of IBr is observed, presumably reflecting the fact that charge localizes mostly in the excited atoms, which can be accounted for mainly by a two step decay via a fast dissociation followed by autoionization upon the VUV absorption

Full Text Available RESUMO Nos últimos anos, o olhar sobre a formação dos profissionais de saúde tem se intensificado, particularmente sobre aquela que possa impactar a resolução dos problemas de saúde da população. Um dos aspectos para o alcance desta demanda refere-se a uma formação que incorpore metodologias ativas no processo ensino-aprendizagem de estudantes da saúde. Neste entendimento, tomando como referência metodologias de aprendizagem baseada em problemas, as quais utilizam certos passos para a resolução de problemas, e diante dos desafios de trabalhar com grandes grupos, desenvolveu-se a estratégia educacional denominada Ciclo de Discussão de Problemas (CDP. Este artigo tem por objetivo descrever o CDP como uma estratégia educacional utilizada em grandes grupos no ensino da graduação em saúde. Esta estratégia ancora-se nos princípios de metodologia ativa, pois utiliza problemas com temáticas comuns aos cursos da área da saúde, para desenvolver nos alunos o aprendizado autodirigido, a habilidade de solucionar problemas, o pensamento crítico e o estudo colaborativo, além da visão integrada das ciências básicas. Esta estratégia envolve dois momentos em sala de aula para cada problema: análise e resolução, englobando 12 passos.

Full Text Available Importantes avanços estão sendo constatados na forma de atuação das empresas. A moderna gestão de empresas descarta a postura convencional da busca pela medição do lucro e rentabilidade e cede espaço a uma gestão voltada à riqueza dos acionistas. O crescimento da competitividade costuma, ainda, exigir vultosos investimentos para ganhos adicionais de market share, avaliados, muitas vezes, como de difícil recuperação econômica. Criar valor aos acionistas demanda estratégias financeiras e novas medidas de sucesso empresarial, voltadas a agregar riqueza aos seus proprietários. Diante disso, exige-se da contabilidade uma atuação mais destacada e sofisticada, visando a cobrir as necessidades de informações dos vários agentes de mercado, dentro de um ambiente de moderna gestão das empresas. Os objetivos do estudo são: (i constatar a importância da contabilidade na moderna administração empresarial; (ii sensibilizar o pesquisador e profissional contábil da premente necessidade de modernização do sistema contábil; (iii apresentar os fundamentos de um modelo de gestão baseada no valor, comparativamente aos procedimentos tradicionais de administração focada nos lucros; e (iv constatar a relevância da informação contábil sob a ótica da essência econômica.Important advances are observed in the way companies perform. Modern company management discards the conventional profit and yield measurement position and gives room to management directed towards shareholder wealth. The growth of competitiveness usually demands great investments with a view to additional market share earnings, whose economic recovery is usually evaluated as difficult. Creating value for the shareholders demands financial strategies and new corporate success measures, aimed at adding wealth for its proprietors. Bearing this in mind, a more outstanding and sophisticated performance is demanded from accounting with a view to covering the information

Full Text Available Background. One-stage direct-to-implant immediate breast reconstruction (IBR is performed simultaneously with breast cancer resection. We explored indications, techniques, and outcomes of IBR to determine its feasibility, safety, and effectiveness. Material and Methods. We reviewed the available literature on one-stage direct-to-implant IBR, with or without acellular dermal matrix (ADM, synthetic mesh, or autologous fat grafting. We analyzed the indications, preoperative work-up, surgical technique, postoperative care, outcomes, and complications. Results. IBR is indicated for small-to-medium nonptotic breasts and contraindicated in patients who require or have undergone radiotherapy, due to unacceptably high complications rates. Only patients with thick, well-vascularized mastectomy flaps are IBR candidates. Expandable implants should be used for ptotic breasts, while anatomical shaped implants should be used to reconstruct small-to-medium nonptotic breasts. ADMs can be used to cover the implant during IBR and avoid muscle elevation, thereby minimizing postoperative pain. Flap necrosis, reoperation, and implant loss are more common with IBR than conventional two-staged reconstruction, but IBR has advantages such as lack of secondary surgery, faster recovery, and better quality of life. Conclusions. IBR has good outcomes and patient-satisfaction rates. With ADM use, a shift from conventional reconstruction to IBR has occurred. Drawbacks of IBR can be overcome by careful patient selection.

One of the problems existing in the area of maintenance of systems for the transport of mass and / or energy is to examine the integrity of the lines of service in the basic infrastructure of cities and industries. For the development of maintenance, whether predictive, preventive or corrective is necessary to conduct the inspection of these lines. To carry out this task is necessary count on help of appropriate technological tools.

One of the problems existing in the area of maintenance of systems for the transport of mass and / or energy is to examine the integrity of the lines of service in the basic infrastructure of cities and industries. For the development of maintenance, whether predictive, preventive or corrective is necessary to conduct the inspection of these lines. To carry out this task is necessary count on help of appropriate technological tools. The main tools for inspection of service lines come from the area of external inspection of pipelines and are also in development, the problem happens when we need to achieve internal or external failures in places of difficult access, and move the inspection equipment to places where it's going to fail.

Full Text Available We investigated the integrated response of antioxidant defense enzymes (total superoxide dismutase (TotSOD, manganese-containing superoxide dismutase (MnSOD, copper-zinc-containing superoxide dismutase (CuZnSOD, catalase (CAT, glutathione peroxidase (GSH-Px, glutathione reductase (GR and phase II biotransformation enzyme, glutathione- S-transferase (GST in the liver and white muscle of females of European hake (Merluccius merluccius L. from the Adriatic Sea (Montenegro in winter and spring. The activity of GSH-Px in the liver was significantly increased, while GST activity was decreased in spring compared to the winter. In white muscle, the activities of TotSOD and CuZnSOD were increased, while the activities of MnSOD, CAT, GSH-Px, GR and GST were decreased in spring when compared to the matching values in winter. The activities of TotSOD and CuZnSOD in winter were markedly lower in the muscle than in the liver, while the activity of MnSOD in the muscle was higher when compared to the liver. Principal component analysis (PCA revealed clear separation of the investigated antioxidant biomarkers between tissues and seasons, while the integrated biomarker response (IBR showed that the most intensive antioxidant biomarker response was in the liver in spring. Star plots of IBR showed a dominant contribution of glutathione-dependent biomarkers (GSH-Px, GR and GST and CAT in both tissues and seasons with respect to SOD isoenzymes. All enzyme activities (except MnSOD were greater in the liver in comparison to the white muscle. Our results show that the liver possesses a greater capacity to establish and maintain homeostasis under changing environmental conditions in winter and spring. At the same time, seasonal effects are more pronounced in muscle tissue. [Project of the Serbian Ministry of Education, Science and Technological Development, Grant no. 173041

Dissociative photoionization of IBr following I(4d) and Br(3d) inner-shell excitations in the range of 60 ∼ 133 eV: remarkable biased charge spread relevant to the core-hole states

International Nuclear Information System (INIS)

Boo, Bong Hyun; Koyano, Inosuke

2002-01-01

Dissociative photoionization of an interhalogen molecule, iodine monobromide (IBr), spanning the I(4d) and the Br(3d) inner-shell excitation/ionization regions has been studied by using time-of-flight (TOF) mass spectrometry coupled to synchrotron radiation in the range of 60 ∼ 133 eV. The total and the individual photoion yields have been recorded as functions of the photon energy. Here, a giant shape resonance has been observed owing to the I(4d 10 ) →I(4d 9 εf) transition, the transition probability for which outweighs that for the Br(3d 10 ) →Br(3d 9 εf) excitation. In addition to the huge resonance, discrete resonances owing to the Br(3d) -1 IBr(4pσ + ) and the Br(3d -1 )Br(5p) transitions, with very weak intensities, are observed at 70.5 and 73.6 eV and have spin-orbit splittings of = 1.0 and = 0.9 eV, respectively. The dissociation processes of singly and doubly charged parent ions have also been evaluated from the variations of the individual ion and photoion-photoion coincidence (PIPICO) yields with the photon energy. Below the Br(3d) threshold, including the Br(3d) discrete excitation region, 60 + and I 2+ ions are exclusively formed with a trace number of Br + ions. Slightly above the Br(3d) threshold, more specifically at 77.5 eV, however, photoionization events leading to the formations of Br + and Br 2- prevail. At higher energies beyond the Br(3d) threshold, 78 + and I 2+ turn out to exceed again those for Br + and Br 2+ , respectively. Over the entire energy range examined, a remarkable biased charge spread in dissociative photoionization events is observed, presumably reflecting the fact that charge localized mostly in the excited atoms relevant to the specific inner-shell excitation, which can be accounted for mainly by a two-step decay process via a fast dissociation followed by autoionization upon vuv absorption

In order to provide reliable information about responsiveness of biomarkers during environmental monitoring, there is a need to improve the understanding of inter-population differences. The present study focused on eight populations of zebra mussels and aimed to describe how variable are biomarkers in different sampling locations. Biomarkers were investigated and summarised through the Integrated Biomarker Response (IBR index). Inter-site differences in IBR index were analysed through comparisons with morphological data, proteomic profiles and genetic background of the studied populations. We found that the IBR index was a good tool to inform about the status of sites. It revealed higher stress in more polluted sites than in cleaner ones. It was neither correlated to proteomic profiles nor to genetic background, suggesting a stronger influence of environment than genes. Meanwhile, morphological traits were related to both environment and genetic background influence. Together these results attest the benefit of using biological tools to better illustrate the status of a population and highlight the need of consider inter-population difference in their baselines.

Full Text Available Foot and mouth disease (FMD and infectious bovine rhinotracheitis (IBR are two important infectious diseases of cattle. Inactivated FMD vaccines are the most powerful tools to protect animals against FMD. Previous studies showed that recombinant IBR-FMD viruses protected cattle from virulent BHV-1 challenge and induced protective levels of anti-FMDV antibodies. FMD is considered to be endemic in Turkey and inactivated oil adjuvanted vaccines are used for the immunization of cattle. Previous studies showed that seroprevalence of IBR in the Turkey’s dairy herd more than 50%. In this study, antibody response in IBR seropositive cattle following vaccination against FMD was investigated. IBR seropositive (n=208 and IBR seronegative (n=212 cattle were vaccinated with oil-adjuvanted bivalent vaccine (containing O1 Manisa, A22 Iraq FMDV strains. Solid-phase competitive ELISA (SPCE was used to measure antibodies produced in cattle. Protective level of antibody against serotype O was detected in 77.4% and serotypes A in 83.6% of IBR seropositive cattle. Protective level of antibody against serotype O antibody was detected in 49% and serotypes A in 66.9% of IBR seronegative cattle. The differences between the protection rates against both serotype O (P=0.0001 and serotype A (P=0.0001 in IBR seropositive and seronegative animals were statistically important (Fisher’s exact test, P<0.01. Results showed that after FMD vaccination, IBR seropositive animals produced high titres of antibodies than seronegative animals.

Full Text Available Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV are diseases that affect cattle population of all breeds, categories and age. Both diseases, especially infectious bovine rhinotracheitis (IBR, poses severe health threat and causes major economic losses and is considered one of the “most costly” disease in cattle industry. The causal agent of the disease is a virus and any detection of IBR/IPV specific antibodies in non-vaccinated cattle, either in blood or milk, indicates that animal is infected and represents the source of infection. Countries with developed and intensive cattle breeding have been developed and implemented their national eradication programs to control IBR/IPV in accordance with international regulations. In this article, we outlined the needs and program for the eradication of IBR/IPV in the Republic of Serbia. The eradication program for IBR/IPV is an extensive process that requires systematic strategy involving different phases and activities. The eradication process from the moment of implementation until obtaining IBR/IPV-free status can last over several years and requires joint work and considerable financial resources that will be compansated with the elimination of IBR/IPV from the herd. This article gives an overview of all stages and activities regarding eradication of the disease and certification and maintaining of IBR/IPV-free herd status.

Immediate implant-based techniques are common practice in post-mastectomy breast reconstruction. Previous studies have shown an increased complication rate in the setting of immediate versus delayed, MD reconstruction. We aimed to quantify any additional risk in complications when implant-based immediate breast reconstruction (IBR) is performed versus mastectomy alone. We retrospectively reviewed all IBR cases and all mastectomies without reconstruction from 2007 to 2011. Patient characteristics, operative details, and complication rates were reviewed and analyzed. IBR was performed in 315 consecutive women; mastectomy alone was performed in 401 women. Patients undergoing mastectomy alone were more often older, diabetic, and more frequently underwent neoadjuvant chemotherapy or radiation. Overall complications were higher in the IBR group, most commonly reoperation and delayed wound healing. In a multivariate analysis, IBR, increasing age, body mass index, history of radiation therapy, smoking, and nipple-sparing mastectomy were independently associated with increased risk of complications. However, IBR was only independently associated with increased risk of major complications such as reoperation or readmission for intravenous antibiotics, not minor complications. Patients selected for IBR are inherently different than those undergoing mastectomy alone. After adjusting for these differences, the increased risk of complications seen in IBR is moderately increased over the risk of complications in mastectomy alone. The observed increased risk of major complications after IBR is largely due to the aggressive management of complications in the setting of a prosthetic implant. IBR is a safe reconstructive strategy with only a slightly increased risk over mastectomy alone.

A New ELISA Using the ANANAS Technology Showing High Sensitivity to diagnose the Bovine Rhinotracheitis from Individual Sera to Pooled Milk.

Directory of Open Access Journals (Sweden)

Elisabetta Casarin

Full Text Available Diagnostic tests for veterinary surveillance programs should be efficient, easy to use and, possibly, economical. In this context, classic Enzyme linked ImmunoSorbent Assay (ELISA remains the most common analytical platform employed for serological analyses. The analysis of pooled samples instead of individual ones is a common procedure that permits to certify, with one single test, entire herds as "disease-free". However, diagnostic tests for pooled samples need to be particularly sensitive, especially when the levels of disease markers are low, as in the case of anti-BoHV1 antibodies in milk as markers of Infectious Bovine Rhinotracheitis (IBR disease. The avidin-nucleic-acid-nanoassembly (ANANAS is a novel kind of signal amplification platform for immunodiagnostics based on colloidal poly-avidin nanoparticles that, using model analytes, was shown to strongly increase ELISA test performance as compared to monomeric avidin. Here, for the first time, we applied the ANANAS reagent integration in a real diagnostic context. The monoclonal 1G10 anti-bovine IgG1 antibody was biotinylated and integrated with the ANANAS reagents for indirect IBR diagnosis from pooled milk mimicking tank samples from herds with IBR prevalence between 1 to 8%. The sensitivity and specificity of the ANANAS integrated method was compared to that of a classic test based on the same 1G10 antibody directly linked to horseradish peroxidase, and a commercial IDEXX kit recently introduced in the market. ANANAS integration increased by 5-fold the sensitivity of the 1G10 mAb-based conventional ELISA without loosing specificity. When compared to the commercial kit, the 1G10-ANANAS integrated method was capable to detect the presence of anti-BHV1 antibodies from bulk milk of gE antibody positive animals with 2-fold higher sensitivity and similar specificity. The results demonstrate the potentials of this new amplification technology, which permits improving current classic ELISA

This cohort study prospectively evaluated the prevalence of the silicone-related symptom complex (SRSC) in relation to antinuclear antibodies (ANA) and magnetic resonance imaging (MRI) of silicone breast implants (SBI) 1 year after implantation. A total of 57 women undergoing mastectomy followed by immediate breast reconstruction (IBR) and SBI between March 1995 and March 1997 at the University Hospital Rotterdam/Daniel den Hoed Cancer Centre, were prospectively evaluated. Just before and 1 year after IBR the sera of these women were tested for the presence of ANA and they were screened for the prevalence of SRSC-related symptoms by questionnaire. All prostheses were evaluated by MRI 1 month and 1 year after IBR. Just before operation 11% of the women had a Sjögren score of more than 2, whereas 30% had such a score 1 year after IBR ( P = 0.01). One year postoperatively women had significantly more RA/Raynaud-related complaints: 21% preoperatively versus 40% 1 year after IBR ( P = 0.03). Within the undefined complaints-related group 19% had a score of 2 or more preoperatively and 33% 1 year after IBR ( P = 0.09). There were no new cases of ANA positivity 1 year after IBR. The linguine sign was seen by MRI in three implants: one 1 month after IBR and two 1 year after IBR. There was no relation to changes in SRSC expression and these MRI findings. In conclusion, 1 year after SBI implantation women had more SRSC-related complaints, especially Sjögren's and RA/Raynaud's. Moreover there was no correlation between elevated SRSC expression and changes in the presence of ANA or changes in MRI of the SBI 1 year after IBR.

Mathematical modeling and thermal flux estimations show that a combination of installations available at present at JINR - the plutonium reactor IBR-30 and the 660 MeV proton phasotron with the current of the extracted beam 0.25 mkA, i.e. 10% of its average value, - allows one to construct an air-cooled electronuclear set-up with the multiplication coefficient K eff ≅ 0.94, the neutron yield N tot ≅ 10 14 - 10 15 and the heat generation about to 10 kW. This set-up will demonstrate a possibility to construct subcritical transmutation-power generating electronuclear systems safe and stable in operation and applicable for utilization of weapon grade and technical plutonium. Kinetics of the electronuclear system will be investigated, in particular, fluctuations of the value of K eff for various parameters of the proton beam. Cross sections of nuclear reactions which are important for the estimations of an efficiency of various conditions of the nuclear waste transmutation and the neutron fluxes together with the heat distributions inside and outside the plutonium core will be measured. A comparison of these data with theoretical calculations allows one to check up and to develop significantly the methods of mathematical modeling of electronuclear systems. We suppose also to estimate the possibilities of ARC-method for the burning of radioactive wastes and to study the influence of various reflectors and multipartitioning of the core which increases the neutron yield.

To compare the postoperative complications after immediate breast reconstruction (IBR) versus mastectomy alone and to examine the impact on the delivery of chemotherapy. In this prospective series, there were 391 consecutive women who underwent mastectomy (243 mastectomy alone and 148 mastectomy and IBR). The outcome measures were complications (within 3 months after surgery) and time to adjuvant chemotherapy. Compared to the IBR group, patients in the mastectomy alone group were significantly older (P previous radiation or lumpectomy (P mastectomy alone (27.0% vs. 15.6%, P = 0.009). Univariate analyses revealed that mastectomy with IBR [odds ratio (OR) = 2, 95% confidence interval (CI) 1.21-2.30]; bilateral procedure (OR = 1.84, 95% CI 1.07-3.16); previous radiotherapy (OR = 2.4, 95% CI 1.29-4.47); and previous lumpectomy (OR = 1.84, 95% CI 1.11-3.03) were significant predictors of increased complications. With multivariable analysis, none of these variables were significantly associated with increased complications. 106 patients received adjuvant chemotherapy; median time from mastectomy to chemotherapy was 6.8 (0.71-15) weeks in the mastectomy alone group (n = 96) compared to 8.5 (6.3-11) weeks in the IBR group (n = 10) (P = 0.01). Although the incidence of overall and major postoperative complications was higher after IBR than mastectomy alone, there were no significant relationships in the multivariable analysis. IBR was associated with a modest increase in time to chemotherapy that was statistically but not clinically significant.

Full Text Available O objetivo deste artigo é despertar o ortodontista e conscientizá-lo sobre a importância da tomada de decisão baseada em evidência científica no cuidado aos pacientes. Serão descritos os passos essenciais para a prática da Odontologia baseada em evidência (OBE, assim como os princípios da ciência e da pesquisa. Existem caminhos adequados para a busca da informação de qualidade, sendo esses a única garantia de encontrar artigos válidos. Na seleção de artigos científicos, o primeiro passo é definir o seu desenho, pois para cada dúvida clínica há um delineamento adequado capaz de respondê-la. Dessa maneira, questões sobre tratamento, etiologia, diagnóstico, prognóstico ou prevenção só podem ser respondidas por um artigo que tenha sido delineado para tal. O conhecimento da alocação randomizada, do mascaramento e do grupo-controle é fundamental para que possamos realizar uma leitura crítica dos artigos científicos, reconhecendo os que merecem credibilidade. Em meio a tantas publicações, precisamos definir, com segurança, o que deve ser incorporado ao nosso conhecimento e o que deve ser incorporado à prática clínica, mudando a nossa conduta. Desse modo, poderemos oferecer aos nossos pacientes opções terapêuticas mais consistentes e previsíveis.The aim of this article is to warn the orthodontist about the importance of making decision based on scientific evidence when taking care of the patients.

Full Text Available O trabalho apresenta as diretrizes sobre educação divulgada pela UNESCO no documento Repensar a Educação. Rumo a um bem comum mundial?, correlacionando-as ao processo formativo pautado na responsabilidade integral. Considerando a necessidade de uma educação aberta à complexidade e à pluralidade das sociedades contemporâneas e que seja capaz de levar adiante a formação de uma cidadania pós nacional, é indispensável contar com estruturas pedagógicas que contemplem a formação do indivíduo em sua plena autonomia, a fim de que ele possa não apenas conviver sob o lastro do “nós”, mas abarque, acima de tudo, uma convivialidade integradora do “todos nós”. A educação, nesse sentido, não pode estar desenraizada dos Direitos Humanos, a saber, dos princípios morais que norteiam um aprendizado integral e responsável, capaz de oportunizar uma convivência não alienada na diversidade de valores éticos que ocupam o mesmo espaço social. Na esteira dos propósitos sobre Educação apresentados pela UNESCO, busca-se demonstrar que uma ação pedagógica baseada no respeito à diversidade cultural não se dá sem um autêntico processo de inclusão do “Eu” ao “Nós” e do “Nós” ao “Todos Nós”.

CF/sub 3/ + IBr (..delta..H/sub 0//sup 0/ = 11 kcal/mole) have been studied by the crossed molecular beams method. Detailed center-of-mass contour maps of the IBr product flux as a function of recoil velocity and scattering angle are derived. For both systems it is found that the IBr product is sharply backward scattered with respect to the incident Br dirction, and that most of the available energy goes into product translation. Vibrational enhancement of the Br + CF/sub 3/I reaction was investigated by using the infrared multiphoton absorption process to prepare highly vibrationally excited CF/sub 3/I. At a collision energy of 31 kcal/mole (several times the barrier height), reagent vibrational energy appears to be less effective than an equivalent amount of (additional) translational energy in promoting reaction. More forward scattered IBr is produced in reactions of Br with vibrationally hot CF/sub 3/I.

Madeira, Diana; Vinagre, Catarina; Mendonça, Vanessa; Diniz, Mário Sousa

Knowledge on baseline values of stress biomarkers in natural conditions is urgent due to the need of reference values for monitoring purposes. Here we assessed the cellular stress response of the chiton Chaetopleura angulata in situ. Biomarkers commonly used in environmental monitoring (heat shock protein 70kDa, total ubiquitin, catalase, glutathione-S-transferase, superoxide-dismutase, lipid peroxidation) were analyzed in the digestive system, gills and muscle of C. angulata, under spring and summer conditions in order to assess seasonal tissue-specific responses. Season had an effect on all targeted organs, especially affecting the digestive system which displayed clear seasonal clusters. The respective Integrated Biomarker Response (IBR) showed a 7.2-fold seasonal difference. Muscle and gills showed similar IBRs between seasons making them appropriate organs to monitor chemical pollution as they were less responsive to seasonal variation. The most stable biomarkers in these organs were ubiquitin and superoxide-dismutase thus being reliable for monitoring purposes. Copyright © 2017 Elsevier Ltd. All rights reserved.

Breast conservation therapy based on liberal selection criteria and less extensive surgery. Analysis of cases with positive margins

International Nuclear Information System (INIS)

Amemiya, Atsushi; Kondo, Makoto

1999-01-01

The relationship between the margin status and the risk of in-breast recurrence (IBR) is an important consideration in patients treated with breast conservation therapy but has not been defined adequately. To address this issue, 1533 clinical stage I and II patients who completed irradiation therapy between 1983 and 1998 were evaluated. Only selection criterion was whether she could be satisfied with cosmesis after lumpectomy. Size and location of the tumor, nodal status, histology and age were not primary consideration. The tumor was excised in such a way to obtain macroscopically clear margins. The breast was treated with 50 Gy of external irradiation but without boost. Margins were evaluated by serially sectioning of the specimen and the margin was judged positive only when cancer cells were present on the inked surface. Margins were also evaluated by scratch cytology. Seventy two IBR were experienced within 5 years. Only age and margin status were found to be independent risk factors. Five-year IBR rate with negative and positive margins was 3.7% and 10.0%, respectively. In patients with positive margins, number of positive site and positive cytology were independent risk factor for IBR. IBR rate among patients with focally involved margins by non-comedo, comedo and invasive ca, was 0.0%, 3.5%, and 8.7%, respectively. IBR rate in more than focal involvement by non-comedo, comedo, and invasive ca, was 4.0%, 33.0% and 30.0%, respectively. If histologically positive margin was also positive cytologically, IBR was 14.8%, whereas only 3.6% if negative cytologically. Even with liberal patient selection and less extensive local treatment, adequate local control can be obtained, provided that margins are histologically and/or cytologically negative. Focal margin involvement by DCIS or more than focal involvement by non-comedo type DCIS does not jeopardize local control. More than focal involvement by comedo DCIS or involvement by invasive ca results in high IBR rate

The neutron activation analysis (NAA) of three samples of human remains of the XVI-XVII centuries from the necropolises of the Moscow Kremlin has been carried out at FLNP JINR. The samples were irradiated at two facilities: at the IREN source of resonance neutrons and at the IBR-2 reactor. Spectra of induced activity of the irradiated samples were measured by using the automatic measurement system developed at FLNP JINR. This system consists of a high-purity germanium detector with spectrometric electronics, a sample changer, and a control software. Mass fractions of arsenic, mercury and other elements were calculated by relative and absolute NAA methods. The obtained values confirmed the fact of an acute mercury poisoning of the first wife of Tsar Ivan Vasilievich the Terrible - Tsarina Anastasia Romanovna. Increased mercury content was detected in the bone remains of the son of Tsar Ivan the Terrible, Tsarevich Ivan Ivanovich, and Prince M. V. Skopin-Shuisky. The obtained results allow us to introduce into scientific circulation the exact values of mass fraction of mercury, arsenic and some other elements in the samples from the graves of Russian historical figures of the second half of XVI - early XVII centuries.

2011-01-01

The NASA Integrated Medical Model (IMM) assesses the risk, including likelihood and impact of occurrence, of all credible in-flight medical conditions. Fatigue due to sleep disruption is a condition that could lead to operational errors, potentially resulting in loss of mission or crew. Pharmacological consumables are mitigation strategies used to manage the risks associated with sleep deficits. The likelihood of medical intervention due to sleep disruption was estimated with a well validated sleep model and a Monte Carlo computer simulation in an effort to optimize the quantity of consumables. METHODS: The key components of the model are the mission parameter program, the calculation of sleep intensity and the diagnosis and decision module. The mission parameter program was used to create simulated daily sleep/wake schedules for an ISS increment. The hypothetical schedules included critical events such as dockings and extravehicular activities and included actual sleep time and sleep quality. The schedules were used as inputs to the Sleep, Activity, Fatigue and Task Effectiveness (SAFTE) Model (IBR Inc., Baltimore MD), which calculated sleep intensity. Sleep data from an ISS study was used to relate calculated sleep intensity to the probability of sleep medication use, using a generalized linear model for binomial regression. A human yes/no decision process using a binomial random number was also factored into sleep medication use probability. RESULTS: These probability calculations were repeated 5000 times resulting in an estimate of the most likely amount of sleep aids used during an ISS mission and a 95% confidence interval. CONCLUSIONS: These results were transferred to the parent IMM for further weighting and integration with other medical conditions, to help inform operational decisions. This model is a potential planning tool for ensuring adequate sleep during sleep disrupted periods of a mission.

In order to assess the quality of streams susceptible to contamination by pesticides we apply biochemical and genotoxic biomarkers in the Neotropical fish Prochilodus lineatus submitted to in situ tests. Fish were caged, for 96 h, in two streams located in areas with intensive use of pesticides, the Apertados (AP) and the Jacutinga (JC), and in a small stream (Godoy stream — GD) found inside a forest fragment adjacent to a State Park. Biochemical parameters, such as biotransformation enzymes 7-ethoxyresorufin-O-deethylase (EROD) and glutathione-S-transferase (GST), non-protein thiols (NPSH), lipoperoxidation (LPO), protein carbonylation (PCO) and acetylcholinesterase (AChE) were evaluated in various fish organs, as well as genotoxic biomarkers (damage to DNA and occurrence of micronuclei and erythrocyte nuclear abnormalities). Samples of water and sediment were collected for analysis of metals (Cu, Cr, Pb, Ni, Mn, Cd and Zn), organochloride pesticides, and triazine and glyphosate herbicides. We observed an increase in liver GST activity in fish at AP and gill GST activity in fish at JC. An increase in liver LPO was also observed in fish exposed to AP and JC. The same animals also exhibited increased DNA damage and erythrocyte nuclear abnormalities (ENAs) compared to the fish kept in GD. A number of compounds showed concentrations higher than the permitted levels, in particular, dichlorodiphenyltrichloroethane (DDT), its metabolites dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexanes (HCH), heptachloride, diclofluanid and aldrins. These pesticides were detected at higher concentrations in water and sediment samples from AP, followed by JC and GD. The Integrated Biomarker Response Index (IBR) indicated that AP and JC (AP: 21.7 > JC: 18.5 > GD: 12.6) have the worst environmental quality. Integrated biomarker analysis revealed that the alterations observed related well with the levels of environmental contaminants

2017-01-01

Full Text Available In the past decade, the wireline robot has received increasing attention due to the advantages of light weight, low cost, and flexibility compared to the traditional drilling instruments in space missions. For the lunar subsurface in situ exploration mission, we proposed a type of wireline robot named IBR (Inchworm Boring Robot drawing inspiration from the inchworm. Two auger tools are utilized to remove chips for IBR, which directly interacted with the lunar regolith in the drilling process. Therefore, for obtaining the tools drilling characteristics, the chips removal principle of IBR is analyzed and its drilling load model is further established based on the soil mechanical theory in this paper. And then the proposed theoretical drilling load model is experimentally validated. In addition, according to the theoretical drilling load model, this paper discusses the effect of the drilling parameters on the tools drilling moments and power consumption. These results imply a possible energy-efficient control strategy for IBR.

The last two decades have seen significant changes in surgical management of breast cancer. The offer of immediate breast reconstruction (IBR) following mastectomy is currently standard practice. Skin sparing and nipple sparing mastectomy with implant-based IBR have emerged as oncologically safe treatment options. Prepectoral implant placement and complete coverage of implant with acellular dermal matrix (ADM) eliminates the need to detach the muscle from underlying chest wall in contrast to the subpectoral technique. We report short-term outcomes of a multicentre study from the United Kingdom (UK) using Braxon ® in women having an IBR. A prospective study was conducted from December 2015 to October 2016 and included all patients from three breast units in the UK who underwent a mastectomy and an implant-based IBR using Braxon ® . The demographic details, co-morbidities, operative details, immediate and delayed complications were recorded. Specific complications recorded were infection, seroma, unplanned readmission and loss of implant. A comparison was made with complications reported in the National Mastectomy and Reconstruction Audit. Seventy-eight IBRs were included in the analysis with a median follow-up of 9.98 months. Mean age of the cohort was 50 years with a mean body mass index of 25.7 kg/m 2 . Mean implant volume was 365 cc. The inpatient hospital stay was 1.48 days. About 23% of patients had a seroma, 30% had erythema requiring antibiotics and the explant rate was 10.2 percent. Bilateral reconstructions were significantly associated with implant loss and peri-operative complications on univariate analysis. Our early experience with this novel prepectoral technique using Braxon ® has shown it to be an effective technique with complication rates comparable to subpectoral IBR. The advantages of prepectoral implant-based IBR are quicker postoperative recovery and short post-operative hospital stay. Long-term studies are required to assess rippling, post

Conversion of Lignocellulosic Biomass to Ethanol and Butyl Acrylate. The purpose of Archer Daniels Midlands Integrated Biorefinery (IBR) was to demonstrate a modified acetosolv process on corn stover. It would show the fractionation of crop residue to distinct fractions of cellulose, hemicellulose, and lignin. The cellulose and hemicellulose fractions would be further converted to ethanol as the primary product and a fraction of the sugars would be catalytically converted to acrylic acid, with butyl acrylate the final product. These primary steps have been demonstrated.

The optimal sequence of mastectomy with immediate breast reconstruction (IBR) and radiotherapy (RT) for the treatment of locally advanced breast cancer (LABC) is still under debate. Increased rates of postoperative complications are described following postmastectomy RT. Neoadjuvant RT aims to improve the aesthetic results and simplify the reconstructive pathway. A total of 22 patients diagnosed with LABC and treated with neoadjuvant RT followed by mastectomy and IBR between 04/2012 and 03/2015 were retrospectively analyzed. RT consisted of external beam RT to the breast and the regional lymphatics, if indicated. Both implant-based and autologous tissue-transfer reconstruction techniques were used. At the time of RT, 10 patients had no prior surgery and 12 patients had previously undergone breast-conserving surgery (BCS) with positive resection margins without the possibility to perform a second BCS. Additional neoadjuvant chemotherapy was administered in 18 patients prior to RT. A complete pathological response was achieved in 55.0% of patients. The 2-year overall survival rate was 89.3%, the 2-year disease-free-survival 79.8% and the local-recurrence-free survival was 95.2%. The cosmetic result was excellent or good in 66% of the patients treated with upfront mastectomy and 37% of the patients who had previously undergone BCS. Among patients who received implant-based IBR, 4 patients developed serious wound-healing problems with implant loss. The most satisfactory results were achieved with autologous tissue reconstruction. A sequential neoadjuvant chemo-/radiotherapy to allow IBR following mastectomy in selected cases of LABC seems feasible and can be safely attempted. Careful patient selection, close monitoring, and continuous patient support is mandatory to ensure compliance in this treatment strategy. (orig.)

A neutron activation analysis (NAA) of three samples of human remains of the 16th and 17th centuries from the necropolises of the Moscow Kremlin has been carried out at FLNP JINR. The samples were irradiated at two facilities: the IREN source of resonance neutrons and the IBR-2 reactor. Spectra of the induced activity of the irradiated samples were measured by using the automatic measurement system developed at the Frank Laboratory of Neutron Physics (FLNP) of the Joint Institute for Nuclear Research (JINR). This system consists of a high-purity germanium detector with spectrometric electronics, a sample changer, and control software. Mass fraction of arsenic, mercury, and some other elements were calculated using two NAA methods—relative and absolute. The obtained values confirm the fact of acute mercury poisoning of Anastasia Romanovna, the first wife of Tsar Ivan Vasil'evich the Terrible, the first Russian Tsarina (died in 1560). High levels of mercury were detected in the bone remains of Tsarevich Ivan Ivanovich (died in 1581), the son of Tsar Ivan the Terrible, and Prince Mikhail Vasil'evich Skopin-Shuiskii (died in 1610). The results provide an opportunity to introduce into scientific circulation the exact values of mass fraction of mercury, arsenic, and other elements in the samples taken from the burials of the Russian historical figures of the second half of 16th-early 17th century.

Variation in rates of breast cancer surgery: A national analysis based on French Hospital Episode Statistics.

Minimum volume thresholds were introduced in France in 2008 to improve the quality of cancer care. We investigated whether/how the quality of treatment decisions in breast cancer surgery had evolved before and after this policy was implemented. We used Hospital Episode Statistics for all women having undergone breast conserving surgery (BCS) or mastectomy in France in 2005 and 2012. Three surgical procedures considered as better treatment options were analyzed: BCS, immediate breast reconstruction (IBR) and sentinel lymph node biopsy (SLNB). We studied the mean rates and variation according to the hospital profile and volume. Between 2005 and 2012, the volume of breast cancer surgery increased by 11% whereas one third of the hospitals no longer performed this type of surgery. In 2012, the mean rate of BCS was 74% and similar in all hospitals whatever the volume. Conversely, IBR and SLNB rates were much higher in cancer centers (CC) and regional teaching hospitals (RTH) [IBR: 19% and 14% versus 8% on average; SLNB: 61% and 47% versus 39% on average]; the greater the hospital volume, the higher the IBR and SLNB rates (p < 0.0001). Overall, whatever the surgical procedure considered, inter-hospital variation in rates declined substantially in CC and RTH. We identified considerable variation in IBR and SLNB rates between French hospitals. Although more complex and less standardized than BCS, most clinical guidelines recommended these procedures. This apparent heterogeneity suggests unequal access to high-quality procedures for women with breast cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

Physicians are still concerned about the oncological safety regarding immediate breast reconstruction (IBR) in breast cancer patients. This study aimed to evaluate possible differences between local, regional, and distant recurrences between women having implant-based reconstruction versus women operated with mastectomy alone. Secondary aims were to evaluate time to oncological treatment as well as disease-free and breast-cancer-specific survival. In a retrospective cohort designed study, 300 reconstructed patients with invasive breast cancer were matched with 300 patients from the population-based Regional Breast Cancer Register of the Stockholm-Gotland health-care region operated with mastectomy alone. They were matched for age, tumor size, nodal stage, and year of operation. Also included were patients treated with neoadjuvant chemotherapy and postoperative radiotherapy. The median follow-up for both the groups was 11.5 years (range 2-20). There were no significant differences in the local recurrence rate, 8.2% in the IBR group and 9.0% in the control group or in the regional recurrence rate, 8.2% versus 9.7%. Distant metastases occurred more frequently in the control group (27.1%) when compared to the IBR group (20.3%). There were no significant differences in time to treatment or in complications rate. Breast cancer mortality was 17% for the IBR group and 23% in the control group during follow-up. This long-term follow-up survey with a well-matched control group demonstrates that IBR with implants is safe to offer patients with invasive breast cancer without any negative effect on the oncological safety.

Pulsed neutron sources at Dubna

International Nuclear Information System (INIS)

Shabalin, E.P.

1991-01-01

In 1960 the first world repetitively pulsed reactor IBR was put into operation. It was the beginning of the story how fission based pulsed neutron sources at Dubna have survived. The engineers involved have experienced many successes and failures in the course of new sources upgrading to finally come to possess the world's brightest neutron source - IBR-2. The details are being reviewed through the paper. The fission based pulsed neutron sources did not reach their final state as yet- the conceptual views of IBR prospects are being discussed with the goal to double the thermal neutron peak flux (up to 2x10 16 ) and to enhance the cold neutron flux by 10 times (with the present one being as high that of the ISIS cold moderator).

Abe, Hiroshi; Kimura, Yasuaki

2018-01-01

Chemical ligation of oligonucleotides (ONs) is the key reaction for various ON-based technologies. We have tried to solve the problems of RNA interference (RNAi) technology by applying ON chemical ligation to RNAi. We designed a new RNAi system, called intracellular buildup RNAi (IBR-RNAi), where the RNA fragments are built up into active small-interference RNA (siRNA) in cells through a chemical ligation reaction. Using the phosphorothioate and iodoacetyl groups as reactive functional groups for the ligation, we achieved RNAi effects without inducing immune responses. Additionally, we developed a new chemical ligation for IBR-RNAi, which affords a more native-like structure in the ligated product. The new ligation method should be useful not only for IBR-RNAi but also for the chemical synthesis of biofunctional ONs.

Full Text Available A teoria da Visão Baseada em Recursos (VBR tem se destacado como uma das mais importantes correntes teóricas da estratégia. O uso da teoria dos recursos mostra-se promissor para a análise das propriedades rurais, permitindo avançar no conhecimento do potencial a ser explorado em torno dos recursos internos. No presente estudo, contribui-se com um levantamento da literatura sobre os principais recursos e/ou fatores-chave determinantes para o desempenho de propriedades rurais por meio da análise de trabalhos que utilizaram a teoria da VBR como base teórica. Com esse levantamento, pretende-se verificar quais recursos foram considerados estratégicos pela literatura da área. A metodologia utilizada foi de revisão sistemática. Os resultados indicaram que o uso da teoria em estudos de empreendimentos agropecuários ainda é incipiente. Foram levantados 14 artigos em fazendas em geral e, dentre esses, três estudos em fazendas produtoras de leite que mostram resultados consistentes quanto ao impacto dos recursos sobre o desempenho. Recursos humanos e organizacionais foram os mais citados como estratégicos e fundamentais para o desempenho. Os recursos físicos foram citados mais vezes em artigos que analisaram o meio rural se comparado à literatura geral do uso da VBR, talvez pela maior dependência de aspectos naturais no desempenho das fazendas em relação aos outros setores da economia. Contudo, devido ao pequeno número de trabalhos encontrados e à diversidade de abordagens em torno da teoria, não é possível realizar inferências, somente concluir que existe um gap de conhecimento nessa área que deve ser suprido por meio de novas e amplas pesquisas.

Bouchard, Alexandre

La famille des composes halogenes et inter-halogenes representent des solides moleculaires adoptant des phases denses communes avec des solides moleculaires diatomiques comme l'azote et l'hydrogene. Parmi les transformations structurales et electroniques induites sous haute pression et observees dans ces solides, on note, entre autres, la dissociation moleculaire et la metallisation. De plus, l'etude des phases denses de l'iode a permis recemment l'observation d'une structure cristalline possedant une modulation dite incommensurable, c'est-a-dire une modulation possedant une periodicite differente de celle de la structure cristalline, jetant ainsi une lumiere nouvelle sur le processus de dissociation moleculaire dans les solides halogenes. Dans ce memoire, on propose d'etudier les changements structuraux dans monobromure d'iode (IBr), un compose inter-halogene possedant des proprietes structurales semblables a celles de deux composes halogenes, soit l'iode (I 2) et le brome (Br2) sous leur forme solide. Des experiences de diffraction des rayons X de poudres en utilisant un rayonnement synchrotron ont ete realisees a temperature ambiante sur l'IBr en variant la pression jusqu'aux environs de 60 GPa. La nature chimique particuliere du compose IBr a necessite la mise au point de techniques de chargement d'echantillon destinees a preserver l'integrite chimique de la substance utilisee. On rapporte egalement l'observation d'une phase de l'IBr presentant une modulation incommensurable. Les phases observees dans l'IBr permettent d'etablir des paralleles avec les phases denses rapportees dans I2 et Br2 par le biais d'un modele phenomenologique decrivant la sequence structurale des solides halogenes sous forme condensee.

This indicates that judgments about one’s own social status modulate the effect of IBR.......Perception of an affordance is enhanced not only when the relevant object is located in one’s own peripersonal space, as compared to when it is located within extrapersonal space, but also when the object is located in another person’s peripersonal space (as measured by a Spatial Alignment Effect......

Purpose: NRG Oncology RTOG 0319 was the first cooperative group trial in the United States to evaluate 3-dimensional conformal radiation therapy (3D-CRT) accelerated partial breast irradiation (APBI). This report updates secondary endpoints of toxicity and efficacy. Methods and Materials: Patients with stage I or II invasive breast cancer (tumor size ≤3 cm, ≤3 positive lymph nodes, negative margins) were eligible for 3D-CRT APBI: 38.5 Gy in 10 twice-daily fractions. Patient characteristics and treatment details have previously been reported. Adverse events were graded with CTCAE v3.0 (National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0). This analysis updates the rates of ipsilateral breast recurrence (IBR), contralateral breast recurrence, ipsilateral node recurrence (INR), metastatic sites (distant metastases [DM]), mastectomy, disease-free survival, mastectomy-free survival, and overall survival. Results: Of 58 enrolled patients, 52 were eligible, with a median age of 61 years; 94% had stage I cancer and 83% had estrogen receptor positive disease. The median follow-up period was 8 years (minimum-maximum, 1.7-9.0 years). The 7-year estimate of isolated IBR (no DM) was 5.9%. The 7-year estimates of all IBRs, INR, mastectomy rate, and DM were 7.7%, 5.8%, 7.7%, and 7.7%, respectively. All 4 IBRs were invasive, of which 3 had a component within the planning target volume. The patterns of failure were as follows: 3 IBRs, 1 INR, 2 DM, 1 INR plus DM, and 1 IBR plus INR plus DM. The 7-year estimates of mastectomy-free survival, disease-free survival, and overall survival were 71.2%, 71.2%, and 78.8%, respectively. Thirteen patients died: 3 of breast cancer and 10 of other causes. Grade 3 (G3) treatment-related adverse events were reported by 4 patients (7.7%). No G3 pain or pulmonary or cardiac toxicities were reported. Conclusions: This phase 1 and 2 trial of 3D-CRT APBI continues to show durable tumor control and minimal G3

Full Text Available Efficacy of an inactivated quadrivalent vaccine containing infectious bovine rhinotracheitis (IBR virus, parainfluenza type 3 (PI3 virus, bovine virus diarrhoea virus (BVDV and bovine respiratory syncytial virus (BRSV was assessed in naive bovine calves to evaluate short-term (4-18 weeks and long-term (24-38 weeks protection following the basic intramuscular vaccination regime of 2 inoculations a month apart. Vaccination was staggered between the long-term and the short-term groups by about 5 months so that both groups, along with a matched group of 6 unvaccinated (control calves, could be challenged at the same time. Sequential challenges at intervals of 3-8 weeks were done in the order: IBR virus (intranasally, IN, PI3 virus (IN and intratracheally, IT, pestiviruses (IN and BRSV (IN and IT. The IBR virus challenge produced febrile rhinotracheitis (FRT in control calves but both the severity and the duration of FRT was significantly reduced in both vaccinated groups. The amount and the duration of IBR virus shed by the vaccinated groups was significantly reduced compared to the control group. Although PI3 virus, pooled pestivirus and BRSV challenges did not result in a noteworthy disease, challenge virus shedding (amount and duration from the upper (all 3 viruses and the lower (BRSV respiratory tracts was significantly reduced in vaccinated groups. After pestivirus challenge, sera and leukocytes from all control calves were infectious for 6-9 days whereas virus was recovered only from leukocytes in vaccinated calves and only for 1.6-2.7 days. Thus a standard course of the quadrivalent vaccine afforded a significant protection against IBR virus, PI3 virus, BVDV and BRSV for at least 6 months.

Full Text Available Fundamento: As diretrizes baseiam-se em evidências para pautar suas recomendações; apesar disso, há uma lacuna entre o recomendado e a prática clínica. Objetivo: Descrever a prática de prescrição de tratamentos com indicação baseada em diretrizes para pacientes com síndrome coronariana aguda no Brasil. Métodos: Foi realizada uma subanálise do registro ACCEPT, na qual foram avaliados os dados epidemiológicos e a taxa de prescrição de ácido acetilsalicílico, inibidores P2Y12, antitrombóticos, betabloqueadores, inibidores da enzima conversora de angiotensina/bloqueadores AT1 e estatinas. Além disso, avaliou-se a qualidade da reperfusão coronariana no infarto com supradesnivelamento do segmento ST. Resultados: Foram avaliados 2.453 pacientes. As taxas de prescrição de ácido acetilsalicílico, inibidores de P2Y12, antitrombóticos, betabloqueadores, inibidores da enzima conversora de angiotensina/bloqueadores AT1 e estatinas foram, respectivamente, de 97,6%, 89,5%, 89,1, 80,2%, 67,9%, 90,6%, em 24 horas, e, respectivamente, de 89,3%, 53,6, 0%, 74,4%, 57,6%, 85,4%, em 6 meses. Com relação ao infarto com supradesnivelamento do segmento ST, somente 35,9% e 25,3% dos pacientes foram submetidos a angioplastia primária e trombólise, respectivamente, nos tempos recomendados. Conclusão: Este registro mostrou altas taxas de prescrição inicial de antiplaquetários, antitrombóticos e estatina, bem como taxas mais baixas de betabloqueadores e de inibidores da enzima conversora de angiotensina/bloqueadores AT1. Independentemente da classe, todos apresentaram queda do uso aos 6 meses. A maioria dos pacientes com infarto com supradesnivelamento do segmento ST não foi submetida a reperfusão coronariana no tempo recomendado.

Mechanism for in-pipe inspection; Dispositivo para inspecao de dutos

Energy Technology Data Exchange (ETDEWEB)

Freitas, Gustavo Medeiros; Dutra, Max Suell [Universidade Federal do Rio de Janeiro (UFRJ), RJ (Brazil)

2008-07-01

The internal inspection of pipes is becoming a routine activity thanks to their importance on transportation of substances such as oil and natural gas. This paper addresses a mechanism capable of working inside pipes of different diameters that may present extreme curves and inclinations. The mechanism is composed of modules with devices that provide adjustable contact with the duct, using wheels on the contact points. The robot moves inside the pipe creating a virtual spindle. For that, two parts are used: the first one, guided along the pipe by a set of wheels, moves parallel to the axis of the pipe; the second part is attached to a motor. The motor rotation forces the mechanism to follow a helical motion, with tilted wheels rotating about the axis of the pipe. Each adjustable contact device works like a lever, pressing the wheel against the pipe. The base of the device can be actively rotated, modifying the angle of the wheel in relation to the pipe (equivalent to the step of the spindle), permitting the motion of the system in both directions, with specific velocity. According to the applied angle, the robot changes the relation between torque and displacement velocity. (author)

Purpose: To examine 10-year rates of local, regional, and distant recurrences, patterns of recurrence, and survival rates for breast cancer patients enrolled on Study NRG Oncology/Radiation Therapy Oncology Group 9517, a multi-institutional prospective trial that studied one of the earliest methods of accelerated partial breast irradiation (APBI), multicatheter brachytherapy (MCT). Methods and Materials: Eligibility included stage I/II unifocal breast cancer <3 cm in size after lumpectomy with negative surgical margins and 0 to 3 positive axillary nodes without extracapsular extension. The APBI dose delivered was 34 Gy in 10 twice-daily fractions over 5 days for high-dose-rate (HDR); and 45 Gy in 3.5 to 5 days for low-dose-rate (LDR) brachytherapy. The primary endpoint was HDR and LDR MCT reproducibility. This analysis focuses on long-term ipsilateral breast recurrence (IBR), contralateral breast cancer events (CBE), regional recurrence (RR), and distant metastases (DM), disease-free, and overall survival. Results: The median follow-up was 12.1 years. One hundred patients were accrued from 1997 to 2000; 98 were evaluable; 65 underwent HDR and 33 LDR MCT. Median age was 62 years; 88% had T1 tumors; 81% were pN0. Seventy-seven percent were estrogen receptor and/or progesterone receptor positive; 33% received adjuvant chemotherapy and 64% antiendocrine therapy. There have been 4 isolated IBRs and 1 IBR with RR, for 5.2% 10-year IBR without DM. There was 1 isolated RR, 1 with IBR, and 1 with a CBE, for 3.1% 10-year RR without DM. The 10-year CBE rate was 4.2%, with 5 total events. Eleven patients have developed DM, 8 have died of breast cancer, and 22 have died from other causes. The 10-year DFS and OS rates are 69.8% and 78.0%, respectively. Conclusion: This multi-institutional, phase 2 trial studying MCT-APBI continues to report durable in-breast cancer control rates with long-term follow-up.

Full Text Available DOI: http://dx.doi.org/10.5007/2175-8077.2013v15n35p152   Este artigo de natureza teórica almeja discutir o papel da gestão ambiental na geração de vantagem competitiva a uma firma. Seu objetivo é verificar em que condições a gestão ambiental pode contribuir com a vantagem competitiva sustentável, segundo os arcabouços teóricos da Visão Baseada em Recursos (VBR e da Teoria Institucional (TI. Para tal, fundamentado no trabalho de Hart (1995, foram sugeridas três estratégias ambientais (Produtividade dos Recursos, Negócios Sustentáveis e Reputação Corporativa por meio das quais se deu o diálogo entre a gestão ambiental, a VBR e a TI. Verificou-se, por intermédio de sete proposições de pesquisas, que a VBR e a TI fornecem referências complementares para entender a relação entre gestão ambiental e vantagem competitiva. A vantagem competitiva, nos termos da VBR, é movida pela capacidade de a empresa em desenvolver e acumular recursos ecológicos valiosos, raros, imperfeitamente imitáveis, insubstituíveis e não-comercializáveis capazes de causar heterogeneidade em relação aos seus concorrentes. A TI evidenciou que as empresas possuem percepções distintas acerca das pressões sociais de natureza ecológicas, porém, reações em direção ao isomorfismo tendem a reduzir o potencial de geração de vantagem competitiva das estratégias ambientais.

Influenza viruses recognize sialoglycans as receptors. Although viruses isolated form chickens preferentially bind to sialic acid α2,3 galactose (SAα2,3Gal) glycans as do those of ducks, chickens were not experimentally infected with viruses isolated from ducks. A chicken influenza virus, A/chicken/Ibaraki/1/2005 (H5N2) (Ck/IBR) bound to fucose-branched SAα2,3Gal glycans, whereas the binding towards linear SAα2,3Gal glycans was weak. On the epithelial cells of the upper respiratory tracts of chickens, fucose-branched SAα2,3Gal glycans were detected, but not linear SAα2,3Gal glycans. The growth of Ck/IBR in MDCK-FUT cells, which were genetically prepared to express fucose-branched SAα2,3Gal glycans, was significantly higher than that in the parental MDCK cells. The present results indicate that fucose-branched SAα2,3Gal glycans existing on the epithelial cells lining the upper respiratory tracts of chickens are critical for recognition by Ck/IBR.

Full Text Available Two hundred and thirty-nine cattle from Gauteng Province in South Africa were tested for various pathogens causing reproductive diseases including bovine viral diarrhoea/mucosal disease (BVD/MD virus, infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IBR/IPV virus, Neospora caninum and Brucella abortus using various tests. For BVD/MD virus, 49.37 % tested positive, 74.47 % for IBR/IPV virus, 8.96 % for Neospora caninum and 3.8 % for Brucella abortus. The result for Brucella abortus is higher than the national average, possibly due to the small sample size. A high seroprevalence of antibodies to both BVD/MD virus and IBR/IPV virus was evident. These 2 viruses should be considered, in addition to Brucella abortus, when trying to establish causes of abortion in cattle. The clinical significance of Neospora caninum as a cause of abortion in Gauteng needs further investigation. One hundred and forty-three bulls were tested for Campylobacter fetus and Trichomonas fetus, and a low prevalence of 1.4 % and 2.1 % respectively was found in this study. The clinical implications of these findings are discussed.

Have Chinese water pricing reforms reduced urban residential water demand?

China continues to deal with severe levels of water scarcity and water pollution. To help address this situation, the Chinese central government initiated urban water pricing reforms in 2002 that emphasized the adoption of increasing block rate (IBR) price structures in place of existing uniform rate structures. By combining urban water use records with microlevel data from the Chinese Urban Household Survey, this research investigates the effectiveness of this national policy reform. Specifically, we compare household water consumption in 28 cities that adopted IBR pricing structures during 2002-2009, with that of 110 cities that had not yet done so. Based on difference-in-differences models, our results show that the policy reform reduced annual residential water demand by 3-4% in the short run and 5% in the longer run. These relatively modest reductions are consistent with the generous nature of the IBR pricing structures that Chinese cities have typically chosen to implement. Our results imply that more efforts are needed to address China's persistent urban water scarcity challenges.

Introduction: The use of best practice guidelines promotes evidence-based care and quality health outcomes. Traditionally, best practice guidelines were designed for use as a paper-based resource. More recently, best practice guidelines have been developed for use on mobile devices such as smartphones. Objective: This reflexive article seeks to document the features and perceived benefits of the RNAO nursing order sets and possible implementation strategies. Topic: With the increased use of electronic medical records and hospital information systems in health care, there is now a growing need for best practice guidelines to be seamlessly integrated within these electronic systems. The Registered Nurses’ Association of Ontario (RNAO has recently developed nursing order sets as one strategy to address this need. Nursing order sets facilitate best practice guideline implementation in electronic environments by delineating clear, concise nursing interventions (derived from the best practice guidelines that can be integrated with an electronic medical record or hospital information system, irrespective of the vendor. Conclusions: The integration of nursing order sets derived from RNAO’s Best Practice Guidelines within electronic or paper-based systems is one innovative solution to the growing need for evidence-informed decision-making at the point of care.

The Radiation Protection and Dosimetry Institute (IRD) of the Brazilian Nuclear Energy Commission (CNEN) is in charge of verifying that the self-monitoring operator is effective to control the radiological quality of environmental around the nuclear facilities and carried out in accordance with the regulatory requirements. While a long time, the verification of compliance was kept by the conduction of large scale monitoring programs around all the authorized installations. The IRD decided to reformulate its performance behavior, starting another kind of control program, due to the number increase of nuclear installations and the diversity of activities conducted by the operators. This program, so-called Monitoring Control Program (PCM) is a regulatory activity developed by the Environmental Impact Assessment Service (SEAIA) of IRD and has the aim of check the effectiveness of authorized self-control. Actually the regulatory control of environmental radiological integrity around the authorized nuclear installation essentially depends on the effectiveness of regulatory inspections fulfilled by the SEAIA/IRD. Due to the implementation of modern practices of management in the IRD, specially the quality management system on regulatory inspection activities, emerged the need of unify these actions. It was also necessary to establish standard procedures required for inspection conduction. This work proposes one methodology for the inspections of environmental radiological control suitable to assure the compliance and effectiveness of environmental and effluent monitoring programs conducted by the operator, through the systematic verification of compliance and data quality assessment. The proposed methodology seeks to attend the appeals for high control standards of environment protection and public health. Here, we presented as products of this work: The inspection handbook and checklists for inspections; one framework for sampling, handling, recording and reporting of

Full Text Available No presente artigo discutiremos como avaliar criticamente as informações obtidas. Para tanto, serão revistos conceitos que a epidemiologia clínica tem colocado à disposição da prática clínica baseada em evidências. A pesquisa clínica busca desenvolver meios diagnósticos e terapêuticos medindo associações, ou relações de causa/efeito, entre um fator em estudo e um desfecho clínico. Onde o fator em estudo é o sintoma, sinal propedêutico, teste laboratorial, exame de imagem, ou tratamento. E o desfecho clínico é o reconhecimento da doença, cura, morte ou limitação. É um erro básico de interpretação tomar os marcadores intermediários como desfechos clínicos. Os desenhos de estudo na área clínica apresentam quatro enfoques principais: diagnóstico, prognóstico, terapêutico, dano/ etiológico. Experimentos animais, estudos anatômicos, fisiológicos, genéticos, farmacológicos, análises econômicas são necessários à formação básica do médico, no entanto, não colaboram diretamente para a tomada de decisão clínica. Os desenhos de estudo são classificados de acordo com a presença de grupo controle, seguimento dos pacientes ao longo do tempo e presença de intervenção dos pesquisadores no sentido de modificar a evolução dos pacientes. A hierarquia da força de evidência científica está fundamentada nestas características e na susceptibilidade aos vícios decorrentes do tipo desenho de estudo. Revisões sistemáticas são consideradas de maior força do que os estudos primários que lhe deram origem, e quando envolvem ensaios clínicos randomizados são colocadas no topo da hierarquia. Desde 1998 é crescente a proporção de "diretrizes clínicas baseadas em evidências" quando comparada às revisões sistemáticas, ou às publicações sobre diretrizes em geral, embora as primeiras sejam ainda em número reduzido. A avaliação crítica do artigo deve responder uma questão clínica, e ser

Justifica-se o desenvolvimento de investigação para identificar barreiras e atitudes face à PBE em contexto comunitário, atendendo à reorganização e centralidade dos Cuidados de Saúde Primários. Os objetivos de pesquisa foram: a identificar barreiras percecionadas face à adoção de uma prática de enfermagem baseada na evidência em contexto comunitário; b descrever as atitudes dos enfermeiros em relação à prática baseada em evidência. Metodologia: Desenvolveu-se um estudo transversal, exploratório e descritivo que decorreu numa unidade local de saúde do norte de Portugal, recorrendo à versão teste do “Questionário de Atitudes face à Prática Baseada em Evidência” (Mckenna, Ashton e Keeney, 2004. Os resultados sobrepõem-se aos dos estudos internacionais embora considerem especificidades nacionais. No geral, as barreiras identificadas são de várias etiologias: pessoal, organizacional, cultural e científica. Em conclusão, uma PBE vai ao encontro da obrigação social da enfermagem, alicerça a sua credibilidade entre as ciências da saúde e sustenta eventuais mudanças ao nível político. É fundamental identificar, barreiras e atitudes, independentemente das suas origens de modo a estruturar estratégias de intervenção futuras.Encuadramiento: Varios estudios han identificado las barreras para la práctica basada en la evidencia (PBE.

The closure of an ocean basin involves the interplay of tectonics and sedimentology, whereby thick successions of fluvio-deltaic and shallow marine sediment accumulate in the closing gap between the subduction zone and passive margin. The transition from subduction to collision involves processes that are inherently time-transgressive and co-evolve to influence the nature of the developing tectonic wedge. The Indo-Burman Ranges (IBR) of eastern India present a unique opportunity to examine this scenario on a variety of spatial (10-2­­­-105 m2) and temporal (1 a-10 Ma) scales. Recent field mapping campaigns in the IBR have illuminated analogous depositional environments expressed in the Neogene outcrops of the IBR and the Holocene sediment archive of the Ganges-Brahmaputra-Meghna delta (GBMD). Six distinct lithofacies are present in shallow-marine to fluvial strata of the IBR, containing sedimentary structures that reflect depositional environments correlative with the modern delta. Cyclical alternations of fine sands and silts in packages on the order of 15-20 cm thick define part of the shallow-marine section (M2 facies) that we interpret to represent the foreset beds of the ancient subaqueous delta. The overall scale and sedimentary structures of M2 compare favorably with modern foreset deposits in the Bay of Bengal. Tan-orange medium-grained, well sorted fluvial sandstone that contain large scale (1-10 m) tabular and trough cross bedding represent large-river channel deposits (F2 facies) that overlie the shallow marine strata. F2 deposits bear a striking resemblance in scale and character to bar deposits along the modern Jamuna River. Preliminary grain size analyses on the F2 facies yield grain size distributions that are remarkably consistent with Brahmaputra-sourced mid-Holocene sediments from Sylhet basin within the GBMD. Current research on the GBMD has revealed quantifiable trends in bed thicknesses, downstream fining, and grain size within fluvial

The development of neutron imaging techniques as a tool for non-destructive analysis of the internal structure, defects and processes in industrial products, functional materials, objects of cultural heritage attracts considerable attention at the present time. The dedicated instruments are available at the many neutron sources. The IBR-2M high flux pulsed reactor is one of the most powerful pulsed neutron sources in the world with the average power 2 MW, power per neutron pulse 1850 MW and neutron flux in pulse of 5·10 15 n/cm 2 /s. During the period December 2006 – December 2010 the reactor was on modernization for replacement of the reactor vessel and fuel elements. During 2011, the successful physical and power start-up of IBR-2M were performed. Now reactor is operational and can be used for research and development activities using neutron scattering techniques in next 25 years prospective. However, no instruments dedicated for neutron imaging is installed at IBR-2M so far. Moreover, in Russian Federation there is no dedicated neutron imaging facility for cultural heritage research at the moment

In July 10, 2012 cold neutrons were generated for the first time with the unique pelletized cold neutron moderator CM-202 at the IBR-2M reactor. This new moderator system uses small spherical beads of a solid mixture of aromatic hydrocarbons (benzene derivatives) as the moderating material. Aromatic hydrocarbons are known as the most radiation-resistant hydrogenous substances and have properties to moderate slow neutrons effectively. Since the new moderator was put into routine operation in September 2013, the IBR-2 research reactor of the Frank Laboratory of Neutron Physics has consolidated its position among the world’s leading pulsed neutron sources for investigation of matter with neutron scattering methods.

Estudos mostram que alianças e parcerias possuem um importante papel na moldagem das vantagens competitivas baseadas em recursos da empresa. Para a concretização dos objetivos propostos nesse estudo, iniciou-se uma investigação em duas redes imobiliárias e adotou-se como pilar metodológico, a tipologia qualitativa de investigação, por fornecer a melhor adequação ao fenômeno observado. Foram utilizados como instrumento: entrevista semi-estruturada, pesquisa bibliográfica e observação não-participante. Conclui-se que os relacionamentos se mostraram importantes e estratégicos para empresas que estão atuando em formato de redes. Como conseqüência direta, o acesso aos parceiros e aos recursos que esses possuem pode ser considerado, como o mais estratégico dos pontos analisados. Como limite metodológico deve ser citado o fato de a pesquisa ser de cunho qualitativo. Os resultados têm pouco campo de generalização se comparados a pesquisas quantitativas. A maior implicação prática que se pode advir dessa pesquisa é levar aos gestores que estão participando de uma rede, a importância estratégica que os relacionamentos possuem. Os gestores deverão considerar, dentro da formulação das suas estratégias, o desenvolvimento e a manutenção de relacionamentos para: terem acessos aos parceiros da rede e aos recursos que esses possuem; e construírem uma posição forte dentro da rede de forma a poderem influenciar outros parceiros.DOI: 10.5585/remark.v9i2.2174

Sobre os obstáculos discursivos para a atenção integral e humanizada à saúde de pessoas transexuais

Rodrigo Borba

Full Text Available Este artigo problematiza alguns obstáculos discursivos para o cuidado integral e humanizado à saúde de pessoas transexuais no Processo Transexualizador brasileiro. Para tanto, faz-se o cotejamento das experiências de Agnes, uma participante da Clínica de Gênero da UCLA na década de 1950, e Vitória, atual usuária de um dos programas de transgenitalização brasileiros, com instâncias classificadoras. Argumenta-se que, embora estejam temporal e geograficamente distantes, Agnes e Vitória engajam-se em performances identitárias muito semelhantes balizadas por uma política narrativo-essencialista que patologiza e homogeneíza as transexualidades. Defende-se que tal política pode ser desafiada por microrresistências narrativo-performativas, i.e., histórias de vida que mostrem às instâncias classificadoras/diagnosticadoras in situ as multiplicidades que constituem nossa vida generificada e possam, enfim, produzir, performativamente, novos regimes identitários em consonância com a fragmentação que nos é constitutiva. Com isso, argumenta-se que a despatologização da transexualidade é central para a construção de relações intersubjetivas entre equipes médicas e usuários/as transexuais baseadas em confiança mútua, salientando, assim, seu potencial para a humanização do cuidado à saúde.

Reactive iodine species have been suggested to play an important role in the atmosphere (e.g. tropospheric ozone depletion, coastal new particle formation). However, there still exist major uncertainties about their atmospheric chemistry, mostly due to the lack of analytical approaches for the accurate speciation of certain key compounds. In this study, 1,3,5-trimethoxybenzene (1,3,5-TMB)-coated denuder proved to be suitable for the differentiation between gaseous interhalogens (iodine monochloride (ICl), iodine monobromide (IBr)) and molecular iodine (I2) based on a selective collection/derivatization method. The results of the denuder sampling were compared with the results of impinger sampling in water, methanol and carbon tetrachloride solutions of 1,3,5-TMB. ICl and IBr are converted into 1-iodo-2,4,6-trimethoxybenzene (1-iodo-2,4,6-TMB) and 1-bromo-2,4,6-trimethoxybenzene (1-bromo-2,4,6-TMB), respectively, in the denuder systems. The respective collection efficiency is 99.2% for ICl and 92.6% for IBr, at 500mLmin(-1) gas flow rate. The collection efficiency for I2 is lower than 1% in the same denuder system, but significantly increases to about 90% in the aqueous 1,3,5-TMB loaded impinger. The denuder-impinger coupled system was then used to differentiate and to collect the ICl, IBr and I2 gas mixtures, followed by gas chromatography-ion trap mass spectrometry (GC-MS) determination. The precision of the method is in general better than 9.1%. The parameters affecting denuder operation including sampling flow rate, sampling duration, and relative humidity have been evaluated. The presented method provides an attractive protocol for iodine species analysis for atmospheric chemistry research.

A distribuição da água precipitada no terreno é obtida como uma consequência da conservação de massa do escoamento, considerada a similaridade hidrológica ao longo de faixas de drenagem, sob diferentes condições de inclinação topográfica, captação e infiltração. A aplicação desse tipo de modelo de distribuição hidrológica permite uma otimização computacional, tanto na estimativa do deficit de saturação do solo quanto na distribuição da profundidade do lençol freático. A aplicabilidade da proposição lagrangiana é exemplificada para um morro suave e também para discutir qualitativamente a hidrologia da Baixada Fluminense encontrada ao norte da Região Metropolitana do Rio de Janeiro (RMRJ, RJ, Brasil.

aos diretores de Sistemas Clínicos antes da implementação do programa e um ano após. Também foram coletados dados sobre como os terapeutas avaliavam as ações relativas à prática baseada em evidências e qual seu grau de satisfação com essa prática. RESULTADOS: Todos os locais de implementação relataram a adoção bem sucedida do programa, ainda que com significativas variações no apoio fiscal, envolvimento familiar, experiência prévia com terapias cognitivo-comportamentais e planos de sustentação em longo prazo. As avaliações dos terapeutas indicaram uma satisfação generalizada com a implementação do projeto. Achados da pesquisa com os diretores dos Sistemas Clínicos apontaram cinco fatores que facilitaram a implementação: 1 rápida adoção e orientação por líderes inovadores (i.e., os diretores; 2 atenção à adequação entre o modelo de intervenção e as práticas locais; 3 atenção desde o início à relação entre os processos de implementação e os usuários finais (e.g., adaptação cultural, tradução, treinamento, problemas fiscais; 4 atenção precoce aos processos de retaguarda do projeto (e.g., sustentação; e 5 estabelecimento de relações estreitas com múltiplos financiadores da instalação do programa. CONCLUSÕES: Os problemas de implementação encontrados neste estudo se assemelham aos identificados em outros estudos sobre a aquisição de práticas baseadas em evidência. Alguns dos obstáculos para a implementação de práticas baseadas em evidência podem ser generalizados, ao passo que problemas como o impacto da instabilidade político-econômica e disponibilidade de materiais traduzidos constituem estressores peculiares que afetam de forma diferenciada os esforços de implementação em cada país.

The neutron spectrometer described in the paper is intended for measurements of the angular and energy distribution of monochromatic slow neutrons, inelasticaily scattered by liquid and solid bodies. Experiments of this type permit detailed information to be obtained concerning the dynamics of the atoms in various aggregate states of a substance. The spectromeeter is based on the time-of-flight method. The pulse source of neutrons is the IBR (1) reactor. A mechanical interrupter, rotating synchronously with the disc of the IBR and having a prescribed phase shift, serves as the monochromator. A special phasing system ensures a phasee stability better than 0.5{sup o}. The neutrons scattered by the sample are recorded by a scintillation detector set at a given angle to the neutron beam. The resolving power of the spectrometer is - 15 {mu}s/m. The paper gives a detailed description of the construction of the spectroscope and its characteristics.

No entanto, a realidade das escolas tem mostrado que poucos são os professores que implementam tais recursos didáticos de forma sistemática em suas aulas. Neste trabalho, buscamos analisar os principais fatores que influenciam na decisão de professores de Física de usar ou não AE e ASC como estratégias de ensino. Amparados na Teoria do Comportamento Planejado de Icek Ajzen, nossos dados indicam que, além de aspectos relacionados com a infraestrutura disponível e com a capacidade que os professores acreditam possuir para a condução dessas atividades, fatores relacionados aos seus conhecimentos teóricos sobre as potencialidades e limitações das AE e ASC no ensino de Física também influenciam nas suas intenções de utilizarem-nas. Os resultados sugerem que os cursos de formação de professores devem direcionar seus esforços não somente no sentido de familiarizar os futuros docentes com um grande leque de experimentos e simulações que os capacitem para utilizarem AE e ASC como estratégias didáticas, mas também para torná-los cientes das potencialidades e limitações teóricas dessas estratégias.

Bond selective photochemistry in CH2BrI through electronic excitation at 210 nm

To explore the possibility of bond selective photochemistry in an excited electronic state, we have studied the photolysis of CH 2 BrI in a molecular beam at 210 nm. Following the direct local excitation of a repulsive transition on the C--Br bond at 210 nm, the fragments were detected by time-of-flight mass spectrometry. The dominant channel was found to be C--Br fission (60%) releasing an average of 15 kcal/mol into translation with the remainder reacting to form CH 2 +IBr and CH 2 +I+Br. There was no evidence for the primary fission of the C--I bond, making this the first clear example of the selective cleavage of a stronger bond in a molecule over the weakest one

Summary: The biological, chemical and physical properties of soil confer unique characteristics that enhance or influence its overall biodiversity. The adaptive character of soil microbial communities (SMCs) to metal pollution allows discriminating soil health, since changes in microbial populations and activities may function as excellent indicators of soil pollutants. Volcanic soils are unique naturally fertile resources, extensively used for agricultural purposes and with particular physicochemical properties that may result in accumulation of toxic substances, such as trace metals (TM). In our previous works, we identified priority TM affecting agricultural Andosols under different agricultural land uses. Within this particular context, the objectives of this study were to (i) assess the effect of soil TM pollution in different agricultural systems (conventional, traditional and organic) on the following soil properties: microbial biomass carbon, basal soil respiration, metabolic quotient, enzymatic activities (β-glucosidase, acid phosphatase and dehydrogenase) and RNA to DNA ratio; and (ii) evaluate the impact of TM in the soil ecosystem using the integrated biomarker response (IBR) based on a set of biochemical responses of SMCs. This multi-biomarker approach will support the development of the "Trace Metal Footprint" for different agricultural land uses in volcanic soils. Methods: The study was conducted in S. Miguel Island (Azores, Portugal). Microbial biomass carbon was measured by chloroform-fumigation-incubation-assay (Vance et al., 1987). Basal respiration was determined by the Jenkinson & Powlson (1976) technique. Metabolic quotient was calculated as the ratio of basal respiration to microbial biomass C (Sparkling & West, 1988). The enzymatic activities of β-glucosidase and acid phosphatase were determined by the Dick et al. (1996) method and dehydrogenase activity by the Rossel et al. (1997) method. The RNA and DNA were co-extracted from the same

Full Text Available Marketing theorists and experts try to develop business efficient organization and to get marketing performance at higher, business integrated level since its earliest beginnings. The core issue in this paperwork is the dialectic and practical approach dilemma should we develop integrated or integral marketing approach in the organization. The presented company cases as well as dialectic and functional explanations of this dilemma clearly shows that integrated marketing is narrower approach than integral marketing if we take as focal point new, unique and completed entity. In the integration the essence is in getting different parts together, which do not have to make necessary the new entity. The key elements in the definition of the integral marketing are necessity and holistic, e.g. necessity to develop new, holistic entity.

Full Text Available China is constructing new commercial buildings at an enormous rate—roughly 2 billion square meters per year, with considerable interest and activity in green design and construction. We review the context of commercial building design and construction in China, and look at a specific project as an example of a high performance, sustainable design, the Shenzhen Institute of Building Research (IBR. The IBR building incorporates over 40 sustainable technologies and strategies, including daylighting, natural ventilation, gray-water recycling, solar-energy generation, and highly efficient Heating Ventilation and Air Conditioning (HVAC systems. We present measured data on the performance of the building, including detailed analysis by energy end use, water use, and occupant comfort and satisfaction. Total building energy consumption in 2011 was 1151 MWh, with an Energy Use Intensity (EUI of 63 kWh/m2 (20 kBtu/ft2, which is 61% of the mean EUI value of 103 kWh/m2 (33 kBtu/ft2 for similar buildings in the region. We also comment on the unique design process, which incorporated passive strategies throughout the building, and has led to high occupant satisfaction with the natural ventilation, daylighting, and green patio work areas. Lastly we present thoughts on how the design philosophy of the IBR building can be a guide for low-energy design in different climate regions throughout China and elsewhere.

One of the obstacles to utilizing rice bran as feed is the presence of antinutrition in the form of phytic acid which binds in minerals to form complex compounds with P, Mg, Mn, Fe, Zn, Ca. Phytic acid and its salts are the main forms of P, Mg, Mn, Fe, Zn, Ca deposits contained in cereals, legume and grains, about 60-90% of total minerals P, Mg, Mn, Fe, Zn, Ca in the form of phytic acid or phytate salts. Phytate is one of the enzymes belonging to the phosphatase group capable of hydrolyzing phytate compounds of myo-inositol (1,2,3,4,5,6) hexsa phosphatase into myo-inositol and organic phosphat. The aim of this study was to obtain characterization of phytase enzymes from isolate Actinobacillus sp., Bacillus pumilus, Bacillus vallimortis and IBR-1. Determination of phytase activity and the absorbance was measured using a UV-Vis spectrophotometer at a wavelength of 392 nm. The result of Actinobacillus sp, Bacillus pumilus, Bacillus vallimortis, IBR-1 each having optimum temperature were 50°C, 40°C, 45°C, 45°C, and optimum pH were 4, 4, 5.5. Bacteria especially Actinobacillus sp, Bacillus pumilus, Bacillus vallimortis, IBR-1 are proven capable of producing the high enough phytase enzymes required for mineral availability for livestock and fish.

Full Text Available BACKGROUND: Long-term disability following natural disasters significantly burdens survivors and the impacted society. Nevertheless, medical rehabilitation programming has been historically neglected in disaster relief planning. 'NHV' is a rehabilitation services program comprised of non-governmental organizations (NGOs (N, local health departments (H, and professional rehabilitation volunteers (V which aims to improve long-term physical functioning in survivors of the 2008 Sichuan earthquake. We aimed to evaluate the effectiveness of the NHV program. METHODS/FINDINGS: 510 of 591 enrolled earthquake survivors participated in this longitudinal quasi-experimental study (86.3%. The early intervention group (NHV-E consisted of 298 survivors who received institutional-based rehabilitation (IBR followed by community-based rehabilitation (CBR; the late intervention group (NHV-L was comprised of 101 survivors who began rehabilitation one year later. The control group of 111 earthquake survivors did not receive IBR/CBR. Physical functioning was assessed using the Barthel Index (BI. Data were analyzed with a mixed-effects Tobit regression model. Physical functioning was significantly increased in the NHV-E and NHV-L groups at follow-up but not in the control group after adjustment for gender, age, type of injury, and time to measurement. We found significant effects of both NHV (11.14, 95% CI 9.0-13.3 and sponaneaous recovery (5.03; 95% CI 1.73-8.34. The effect of NHV-E (11.3, 95% CI 9.0-13.7 was marginally greater than that of NHV-L (10.7, 95% CI 7.9-13.6. It could, however, not be determined whether specific IBR or CBR program components were effective since individual component exposures were not evaluated. CONCLUSION: Our analysis shows that the NHV improved the long-term physical functioning of Sichuan earthquake survivors with disabling injuries. The comprehensive rehabilitation program benefitted the individual and society, rehabilitation services

The management of early breast cancer (BC) with skin-sparing mastectomy (SSM) and immediate breast reconstruction (IBR) is not based on level-1 evidence. In this study, the oncological outcome, post-operative morbidity and patients' satisfaction with SSM and IBR using the latissimus dorsi (LD) myocutaneous flap and/or breast prosthesis is evaluated. 137 SSMs with IBR (10 bilateral) were undertaken in 127 consecutive women, using the LD flap plus implant (n = 85), LD flap alone (n = 1) or implant alone (n = 51), for early BC (n = 130) or prophylaxis (n = 7). Nipple reconstruction was performed in 69 patients, using the trefoil local flap technique (n = 61), nipple sharing (n = 6), skin graft (n = 1) and Monocryl mesh (n = 1). Thirty patients underwent contra-lateral procedures to enhance symmetry, including 19 augmentations and 11 mastopexy/reduction mammoplasties. A linear visual analogue scale was used to assess patient satisfaction with surgical outcome, ranging from 0 (not satisfied) to 10 (most satisfied). After a median follow-up of 36 months (range = 6-101 months) there were no local recurrences. Overall breast cancer specific survival was 99.2%, 8 patients developed distant disease and 1 died of metastatic BC. There were no cases of partial or total LD flap loss. Morbidities included infection, requiring implant removal in 2 patients and 1 patient developed marginal ischaemia of the skin envelope. Chemotherapy was delayed in 1 patient due to infection. Significant capsule formation, requiring capsulotomy, was observed in 85% of patients who had either post-mastectomy radiotherapy (PMR) or prior radiotherapy (RT) compared with 13% for those who had not received RT. The outcome questionnaire was completed by 82 (64.6%) of 127 patients with a median satisfaction score of 9 (range = 5-10). SSM with IBR is associated with low morbidity, high levels of patient satisfaction and is oncologically safe for T(is), T1 and T2 tumours without extensive skin

O objetivo da utilização de tal metodologia é a exposição do aluno a situações muito próximas das que encontrará em sua vida profissional, futuramente. Uma das competências que se espera de um bom profissional de engenharia é a atuação como líder ou liderado pois, invariavelmente, estará em uma das posições. Considerando que, nos últimos anos, o enfoque sobre liderança vem sofrendo modificações em função das necessidades do mercado, passando de uma posição fixa para um conjunto de atributos desejáveis, o objetivo deste trabalho é analisar a percepção dos alunos sobre tal competência. Em 2015, foi realizado um estudo de caso com alunos do 1º semestre do curso, num total de 41, distribuídos em 6 equipes com 6 ou 7 integrantes cada uma delas. Na aplicação da ABPj foram designados, entre os membros de cada equipe, dois líderes: O primeiro, voluntário, na primeira aula e o segundo, escolhido pelo grupo, no meio do semestre. Os dados foram coletados por meio de questionários aplicados, no meio e o no final do semestre, e da compilação e análise de registros dos alunos no aplicativo whatsapp, utilizado durante todo o período por todas as equipes. Os resultados obtidos permitiram identificar uma valorização positiva da figura do líder ao longo do projeto, sendo o segundo líder melhor avaliado do que o primeiro. Além disso, nas conversas do whatsapp foi possível verificar a valorização de atitudes como iniciativa, comunicação constante, compartilhada e participativa, organização e responsabilização

Numerical simulation of in-situ chemical oxidation (ISCO) and biodegradation of petroleum hydrocarbons using a coupled model for bio-geochemical reactive transport

Science.gov (United States)

Marin, I. S.; Molson, J. W.

2013-05-01

Petroleum hydrocarbons (PHCs) are a major source of groundwater contamination, being a worldwide and well-known problem. Formed by a complex mixture of hundreds of organic compounds (including BTEX - benzene, toluene, ethylbenzene and xylenes), many of which are toxic and persistent in the subsurface and are capable of creating a serious risk to human health. Several remediation technologies can be used to clean-up PHC contamination. In-situ chemical oxidation (ISCO) and intrinsic bioremediation (IBR) are two promising techniques that can be applied in this case. However, the interaction of these processes with the background aquifer geochemistry and the design of an efficient treatment presents a challenge. Here we show the development and application of BIONAPL/Phreeqc, a modeling tool capable of simulating groundwater flow, contaminant transport with coupled biological and geochemical processes in porous or fractured porous media. BIONAPL/Phreeqc is based on the well-tested BIONAPL/3D model, using a powerful finite element simulation engine, capable of simulating non-aqueous phase liquid (NAPL) dissolution, density-dependent advective-dispersive transport, and solving the geochemical and kinetic processes with the library Phreeqc. To validate the model, we compared BIONAPL/Phreeqc with results from the literature for different biodegradation processes and different geometries, with good agreement. We then used the model to simulate the behavior of sodium persulfate (NaS2O8) as an oxidant for BTEX degradation, coupled with sequential biodegradation in a 2D case and to evaluate the effect of inorganic geochemistry reactions. The results show the advantages of a treatment train remediation scheme based on ISCO and IBR. The numerical performance and stability of the integrated BIONAPL/Phreeqc model was also verified.

Integration of Chandrasekhar's integral equation

International Nuclear Information System (INIS)

Tanaka, Tasuku

2003-01-01

We solve Chandrasekhar's integration equation for radiative transfer in the plane-parallel atmosphere by iterative integration. The primary thrust in radiative transfer has been to solve the forward problem, i.e., to evaluate the radiance, given the optical thickness and the scattering phase function. In the area of satellite remote sensing, our problem is the inverse problem: to retrieve the surface reflectance and the optical thickness of the atmosphere from the radiance measured by satellites. In order to retrieve the optical thickness and the surface reflectance from the radiance at the top-of-the atmosphere (TOA), we should express the radiance at TOA 'explicitly' in the optical thickness and the surface reflectance. Chandrasekhar formalized radiative transfer in the plane-parallel atmosphere in a simultaneous integral equation, and he obtained the second approximation. Since then no higher approximation has been reported. In this paper, we obtain the third approximation of the scattering function. We integrate functions derived from the second approximation in the integral interval from 1 to ∞ of the inverse of the cos of zenith angles. We can obtain the indefinite integral rather easily in the form of a series expansion. However, the integrals at the upper limit, ∞, are not yet known to us. We can assess the converged values of those series expansions at ∞ through calculus. For integration, we choose coupling pairs to avoid unnecessary terms in the outcome of integral and discover that the simultaneous integral equation can be deduced to the mere integral equation. Through algebraic calculation, we obtain the third approximation as a polynomial of the third degree in the atmospheric optical thickness

Full Text Available O presente trabalho descreve o fenômeno da proliferação das rupturas paradigmáticas publicadas na literatura biomédica. É discutida a distorção que, com o passar das décadas, atribuiu um sentido oposto ao original proposto por Thomas Khun. Na sua grande maioria percebemos que essas pseudo-rupturas se relacionam meramente a detalhes técnicos ligados a contextos específicos. Destaca-se o caso da medicina baseada em evidências (MBE, anunciada como uma dessas rupturas, em cuja essência se reafirmam antigas concepções. Alguns equívocos conceituais são enfatizados como tentativas de aplicar os pressupostos da MBE a fenômenos ligados à subjetividade e à dinâmica social, além de outros objetos de estudo peculiares às ciências sociais. São citadas 12 metanálises inconclusivas, que originam paradoxos quando estudados por esta via. A crítica a alguns aspectos da MBE é sintetizada pelo de seu efeito de confundimento epistemológico. Há imprecisões conceituais do termo relacionadas ao efeito de "entrincheiramento", ao qual são induzidos outros modelos epistemológicos não alinhados, assim como a tendência à compreensão universal dos fenômenos pela perspectiva dos estudos duplo-cego randomizados.The present study describes the phenomenon of paradigmatic ruptures proliferation in the biomedical literature. The current distortion is discussed, which has conferred in the last decades an opposite meaning to the term originally proposed by Thomas Khun. In most part, it is realized that pseudo-ruptures refer to technical details associated to specific contexts. It is pointed out the case of evidence- based medicine (EBM, proclaimed as one of these paradigmatic ruptures, but which essentially corroborates old concepts. Some conceptual errors are stressed as well as attempts to apply EBM assumptions to phenomena associated to subjectivity and social dynamics and other particular study subjects of social sciences.

Full Text Available A diversidade genética de fungos micorrízicos arbusculares, recuperados de três estádios de estabilização de dunas, foi avaliada por técnicas moleculares e comparada com resultados obtidos anteriormente por técnicas baseadas na caracterização morfológica dos esporos. O uso da técnica de PCR-RFLP do rDNA, extraído de esporos, permitiu definir impressões características de espécies presentes nas dunas, evidenciar a presença de diferentes comunidades em cada estádio e identificar a anteduna como aquela com comunidades com maior polimorfismo. Esse estádio também apresentou maior diversidade, quando, no estudo das comunidades, foram utilizadas técnicas baseadas em aspectos morfológicos. A combinação de ambas as estratégias, molecular e baseada em aspectos morfológicos, forneceu importantes informações sobre a diversidade destes fungos, visando ao estudo do seu papel no ecossistema.

China is constructing new commercial buildings at an enormous rate -- roughly 2 billion square meters per year, with considerable interest and activity in green design and construction. We review the context of commercial building design and construction in China, and look at a specific project as an example of a high performance, sustainable design, the Shenzhen Institute of Building Research (IBR). The IBR building incorporates over 40 sustainable technologies and strategies, including daylighting, natural ventilation, gray-water recycling, solar-energy generation, and highly efficient Heating Ventilation and Air Conditioning (HVAC) systems. We present measured data on the performance of the building, including detailed analysis by energy end use, water use, and occupant comfort and satisfaction. Total building energy consumption in 2011 was 1151 MWh, with an Energy Use Intensity (EUI) of 63 kWh/m² (20 kBtu/ft²), which is 61% of the mean EUI value of 103 kWh/m² (33 kBtu/ft²) for similar buildings in the region. We also comment on the unique design process, which incorporated passive strategies throughout the building, and has led to high occupant satisfaction with the natural ventilation, daylighting, and green patio work areas. Lastly we present thoughts on how the design philosophy of the IBR building can be a guide for low-energy design in different climate regions throughout China and elsewhere.

Radiation inactivation of Infectious Boivne Rhinotracheitis (IBR) virus was investigated by suspending in a commercial preparation medium (c.p.m.) or IBR antibody free serum and irradiated at room temperature or dry ice frozen condition. Normal pooled serum was also analysed by electrophoresis with cellulose acetate membrane after irradiation at frozen and non-frozen condition. The virus inactivation was determined by MDBK cell line which 50 % tissue culture infectious dose (TCID 50 ) was calculated by Behrens Kaerber method. D 10 value at non-frozen condition in serum was obtained as 1.1-1.2 kGy and that in c.p.m. was 1.3-1.4 kGy. On the other hand, D 10 value was increased to 3.4-3.6 kGy in serum and 3.9 kGy in c.p.m. at frozen condition. On the irradiation effect of bovine serum, four peaks of albumin, α, β and γ-globulin fraction were obtained from non-irradiation and irradiated serum up to 2 kGy at non-frozen condition by electrophoresis. More than 4 kGy irradiation, the peaks of globulin fractions became not clear and at more than 8 kGy, changed to one large peak. On the other hand, these changes of electrophoretic patterns were not observed even at 30 kGy irradiation in frozen condition. From these results, necessary dose was decided as 20-25 kGy at frozen condition for inactivation of IBR virus in serum. (author)

Utilization of breast reconstruction (BR) is low in many jurisdictions. We studied the geographical and surgical workforce factors that contribute to access and use of BR using a small area analysis approach with a geographical unit of analysis. We linked administrative data from Ontario Canada to calculate the age-standardized rates for immediate BR (IBR) (same time as mastectomy) between 2002 and 2011, and delayed BR (DBR) (within 3 years of mastectomy) for each county. The influence of plastic surgeon access on variation in county rates of BR was examined using Poisson random effects models. 12,663 women underwent mastectomy in Ontario; 2,948 had BR within 3 years (23.3%). Over 50% of the counties had no access to any plastic surgeon. County IBR rates ranged from 0 to 21.5%; plastic surgeon access explained 46% of geographic variation (pplastic surgeons were significantly less than counties with high access (relative rate [RR] 0.48 [95% confidence interval (CI) 0.35-0.66], RR 0.61 [CI 0.43-0.87] and RR 0.70 [CI 0.52-0.96], respectively) after adjusting for age and county socioeconomic characteristics. For DBR, while there was less geographic variation, very low access counties demonstrated reduced rates (RR 0.60 [CI 0.47-0.76]). Geographic access to a plastic surgeon is a major determinant of BR. Targeted interventions for regions without high access to plastic surgeons may improve overall rates and reduce geographic disparities in care, particularly for IBR.

Long Pulse Integrator of Variable Integral Time Constant

International Nuclear Information System (INIS)

2010-01-01

A kind of new long pulse integrator was designed based on the method of variable integral time constant and deducting integral drift by drift slope. The integral time constant can be changed by choosing different integral resistors, in order to improve the signal-to-noise ratio, and avoid output saturation; the slope of integral drift of a certain period of time can be calculated by digital signal processing, which can be used to deduct the drift of original integral signal in real time to reduce the integral drift. The tests show that this kind of long pulse integrator is good at reducing integral drift, which also can eliminate the effects of changing integral time constant. According to experiments, the integral time constant can be changed by remote control and manual adjustment of integral drift is avoided, which can improve the experiment efficiency greatly and can be used for electromagnetic measurement in Tokamak experiment.

2017-06-01

The Indo-Burma Range (IBR) of Myanmar, the eastern extension of the Yarlung-Tsangpo Neotethyan belt of Tibet in China, contains mélanges with serpentinite, greenschist facies basalt, chert, sericite schist, silty slate and unmetamorphosed Triassic sandstone, mudstone and siltstone interbedded with chert in the east, and farther north high-pressure blueschist and eclogite blocks in the Naga Hills mélange. Our detailed mapping of the Mindat and Magwe sections in the middle IBR revealed a major 18 km antiformal isocline in a mélange in which greenschist facies rocks in the core decrease in grade eastwards and westwards symmetrically `outwards' to lower grade sericite schist and silty slate, and at the margins to unmetamorphosed sediments, and these metamorphic rocks are structurally repeated in small-scale imbricated thrust stacks. In the Mindat section the lower western boundary of the isoclinal mélange is a thrust on which the metamorphic rocks have been transported over unmetamorphosed sediments of the Triassic Pane Chaung Group, and the upper eastern boundary is a normal fault. These relations demonstrate that the IBR metamorphic rocks were exhumed by wedge extrusion in a subduction-generated accretionary complex. Along strike to the north in the Naga Hills is a comparable isoclinal mélange in which central eclogite lenses are succeeded `outwards' by layers of glaucophane schist and glaucophanite, and to lower grade greenschist facies sericite schist and slate towards the margins. In the Natchaung area (from west to east) unmetamorphosed Triassic sediments overlie quartzites, sericite schists, actinolite schists and meta-volcanic amphibolites derived from MORB-type basalt, which are in fault contact with peridotite. Olivine in the peridotite has undulatory extinction suggesting deformation at 600-700 °C, similar to the peak temperature of the amphibolite; these relations suggest generation in a metamorphic sole. The amphibolites have U/Pb zircon ages of 119

What is the Integral in Integral Education? From Progressive Pedagogy to Integral Pedagogy

Tom Murray

2009-06-01

Full Text Available Integrally-informed educational approaches have much in common withprogressive (including reform, alternative, holistic, and transformative approaches, andshare many of the same values. One function of the integral approach is to provide anoverarching model within which to coordinate different progressive methods. Thoughintegral adds much more than that, descriptions of integral education sometimes soundlike progressive educational principles recast with new terminology. This essay attemptsto clarify what the integral approach adds over and above progressive educationaltheories. After an overview of progressive pedagogical principles, the integral approachis discussed in terms of integral as a model, a method, a community, and a developmentalstage. Integral as a type of consciousness or developmental level is elaborated upon asconsisting of construct-awareness, ego-awareness, relational-awareness, and systemawareness,all important to the educational process. Finally, challenges and supportsystems for realizing integral education are discussed.

Full Text Available Based on an integral healthcare model for the users of alcohol and other drugs, the expansion of Brazil's Psycho-Social Care Centers - Alcohol and Drugs (CAPS-AD is guided by the acknowledgement of users as citizens rather than patients, aiming at social reinsertion through an intersectoral approach and damage control, as well as other principles designed to build up integral healthcare services that are fair and egalitarian. This paper examines alcohol and drug users, their companions and healthcare practitioners in terms of the existing healthcare model, through a study conducted at two Psycho-Social Care Centers - Alcohol and Drugs in Recife, Pernambuco State. Focus groups, participative observation and documentary surveys were used to analyze the daily work routines at these Centers, exploring player perceptions and therapeutic projects. The findings indicate that users are still perceived as being ill, with medicalization and other traces of care models not used since the Psychiatric Reform. Social reinsertion was perceived as the main obstacle in integral healthcare. Restructuring this practice seems necessary, in order to break away from a culture of prejudice, exclusion and illness, as well as control models based on hospital-centric psychiatry.No Brasil, a expansão dos CAPS-AD, baseada em um modelo de atenção integral à saúde de usuários de álcool e outras drogas, preconiza a passagem da idéia de doentes para a de cidadãos; reinserção social e intersetorialidade das ações; adoção da redução de danos e outros princípios para atenção integral justa e equânime; entretanto, a literatura aponta para manutenção da lógica de controle que surge com o saber médico do século XVIII. O objetivo desse trabalho foi investigar a percepção de usuários, acompanhantes e profissionais, acerca do modelo de atenção à saúde de usuários de drogas.

Information-based regulations (IBRs) are founded on the theoretical premise that public participation in accomplishing policy goals is empowered by open access to information. Since its inception in 1988, the Toxics Release Inventory (TRI) has provided the framework and regulatory impetus for the compilation and distribution of data on toxic releases associated with industrial development, following the tenets of IBR. As TRI emissions are reputed to disproportionately affect low-income communities, we investigated how demographic characteristics are related to change in TRI emissions and toxicity risks between 1989 and 2002, and we sought to identify factors that predict these changes. We used local indicators of spatial association (LISA) maps and spatial regression techniques to study risk disparity in the Los Angeles urban area. We also surveyed 203 individuals in eight communities in the same region to measure the levels of awareness of TRI, attitudes towards air pollution, and general environmental risk. We discovered, through spatial lag models, that changes in gross and toxic emissions are related to community ethnic composition, poverty level, home ownership, and base 1989 emissions (R-square=0.034-0.083). We generated a structural equation model to explain the determinants of social empowerment to act on the basis of environmental information. Hierarchical confirmatory factor analysis (HCFA) supports the theoretical model that individual empowerment is predicted by risk perception, worry, and awareness (Chi-square=63.315, p=0.022, df=42). This study provides strong evidence that spatiotemporal changes in regional-scale environmental risks are influenced by individual-scale empowerment mediated by IBRs.

[Integrity].

Gómez Rodríguez, Rafael Ángel

2014-01-01

To say that someone possesses integrity is to claim that that person is almost predictable about responses to specific situations, that he or she can prudentially judge and to act correctly. There is a closed interrelationship between integrity and autonomy, and the autonomy rests on the deeper moral claim of all humans to integrity of the person. Integrity has two senses of significance for medical ethic: one sense refers to the integrity of the person in the bodily, psychosocial and intellectual elements; and in the second sense, the integrity is the virtue. Another facet of integrity of the person is la integrity of values we cherish and espouse. The physician must be a person of integrity if the integrity of the patient is to be safeguarded. The autonomy has reduced the violations in the past, but the character and virtues of the physician are the ultimate safeguard of autonomy of patient. A field very important in medicine is the scientific research. It is the character of the investigator that determines the moral quality of research. The problem arises when legitimate self-interests are replaced by selfish, particularly when human subjects are involved. The final safeguard of moral quality of research is the character and conscience of the investigator. Teaching must be relevant in the scientific field, but the most effective way to teach virtue ethics is through the example of the a respected scientist.

Full Text Available Existem (ou existiram outras espécies de criaturas simbólicas? Essa questão tem sido abordada por pesquisadores de diversas áreas e é responsável por uma histórica controvérsia sobre a existência de um limiar entre "criaturas simbólicas" vs "criaturas capazes de produzir formas simples de linguagem". Conforme o mainstream em Etologia e Psicologia Comparada apenas o Homo sapiens está cognitivamente equipado para produzir e interpretar símbolos. Vou introduzir um modelo empiricamente testável de semiose simbólica ("ação simbólica do signo", baseada na teoria das categorias lógico-fenomenológicas de C.S.Peirce. Vou sugerir que um padrão específico de comportamento do usuário do signo, observado na comunicação de primatas não-humanos, indica a transição de uma semiose indexical para uma simbólica.Are (or were there any other symbolic species? This question has been addressed by researchers from many different fields and is responsible for a historical controversy on the existence of a threshold between "symbolic creatures" vs "simple forms of language creatures". According to the mainstream ethology and comparative psychology only the Homo sapiens is cognitively equiped to produce and interpret symbols. Here, I introduce an empirically testable model of symbolic semiosis ("symbolic action of sign" supported by C.S.Peirce logical-phenomenological theory of categories. I suggest that a specific sign-user pattern of behavior, observed in non-human primate communication, indicate a transition from indexical to symbolic semiosis.

As a scientific and engineering endeavor, the Algenol IBR Biorefinery project has been a success by almost any measure. The vision for the system evolved significantly over the course of the project, always due to recognized opportunities for improved performance, lower energy consumption, and reduced costs. Our commitment to thorough, realistic, techno-economic and life cycle assessments has been an essential element for system innovation, technology guidance, and change management of the overall facility. The biological tools developed during this program for cyanobacteria are second to none, and are the primary reason for the remarkable improvements in organism performance. The breakthrough was the successful transformation of our most robust wild type organism (AB1) early in 2012. That was followed by a series of improvements over the next several years that produced strains wherein over 80% of the fixed carbon was converted into ethanol. At the same time, our expertise in cultivation, physiology, process engineering, CO2 management, and photobioreactor design and manufacturing grew at a comparable pace. We learned enormous amounts from the various upsets, weather variations, contamination events, and new technology related disappointments. We overcame those challenges to produce fuel grade ethanol with a low carbon footprint, and are within striking distance of economic viability even with the challenges of low fossil fuel prices.

This work presents the development of a 3D localization system based on inertial sensors. The prototype aims for its application in the oil and gas industry, which presents deficiencies on automation of inspection procedures. Recent advances on the field of Nondestructive Testing (NDT) have contributed to automation of these inspections, but installation and removal of NDT equipment, as well as location measurements and data acquired processing, are still highly dependent on labour-human. However, only the double integration of data from the inertial sensors - position determination - does not reach the precision level required by inspection activity. It requires the use of techniques and methods to minimize errors. Different models and techniques can be applied to minimize these undesired effects in addition with filters as the Kalman filter, widely used on problems of estimation of trajectories and fusion of sensors. This paper presents the modeling and implementation of some of these techniques, obtaining interesting results. (author)

2002-01-01

The fear of speaking is often cited as the world's most common social phobia. The rapid growth of computer technology has enabled the use of virtual reality (VR) for the treatment of the fear of public speaking. There are two techniques for building virtual environments for the treatment of this fear: a model-based and a movie-based method. Both methods have the weakness that they are unrealistic and not controllable individually. To understand these disadvantages, this paper presents a virtual environment produced with Image Based Rendering (IBR) and a chroma-key simultaneously. IBR enables the creation of realistic virtual environments where the images are stitched panoramically with the photos taken from a digital camera. And the use of chroma-keys puts virtual audience members under individual control in the environment. In addition, real time capture technique is used in constructing the virtual environments enabling spoken interaction between the subject and a therapist or another subject.

NAA for applied investigations at FLNP JINR. Present and future

Frontasyeva, M.V.; Pavlov, S.S.; Shvetsov, V.N.

2010-01-01

Experience in applying conventional and epithermal neutron activation analysis for some challenging areas of life sciences and material science is reviewed. For more than 30 years of its operation the radioanalytical complex REGATA at the IBR-2 reactor in Dubna has become a source of analytical data for the environmental studies, marine geology, biotechnology and medicine, technological process of diamond and boron nitride synthesis, archaeology, nanomaterials, etc. In spite of competing non-nuclear analytical techniques (AAS, ICP-ES, ICP-MS, etc.), the reactor neutron activation analysis (NAA) as a primary (ratio) method continues to be the most powerful multielement analytical technique providing quantification of trace elements at ultralow levels. Combined with modern statistical data treatment of large arrays of data, GIS (geographic information system) technologies, electron scanning microscopy, tomography, and others, NAA serves to obtain actual, practical results resumed in the review. The perspectives of using the upgraded reactor IBR-2M for analytical investigations are discussed. (author)

Implementing interprofessional bedside rounding at the prequalification stage

Directory of Open Access Journals (Sweden)

Tuite DR

2016-10-01

Full Text Available Daniel R Tuite,1 David Healy,1 Thomas S MacKinnon2 1Faculty of Medicine, Brighton and Sussex Medical School, Brighton, 2School of Medicine, Imperial College London, London, UKWe read with great interest the paper by Henkin et al,1 demonstrating that the use of interprofessional bedside rounding (IBR significantly improved nurse–physician teamwork, particularly from the nurses’ point of view. This finding is relevant when one takes into account the importance of interdisciplinary teamwork; a review conducted by Epstein concluded that effective interprofessional teamwork both maximizes patient safety and increases job satisfaction and efficiency.2 We, as medical students, believe that inadequate emphasis is placed on interprofessional collaboration at the prequalification phase, and therefore, we suggest that implementing IBR at the university level could represent a method to improve teamwork between the nurses and doctors of the future.  View the original paper by Henkin et al.  

COMMUNITY BASED HOME ENERGY MANAGEMENT SYSTEM

Directory of Open Access Journals (Sweden)

Muhammad Adnan Aziz

2017-05-01

Full Text Available In a Smart Grid (SG scenario, domestic consumers can gain cost reduction benefit by scheduling their Appliance Activation Time (AAT towards the slots of low charge. Minimization in cost is essential in Home Energy Management Systems (HEMS to induce consumers acceptance for power scheduling to accommodate for a Demand Response (DR at peak hours. Despite the fact that many algorithms address the power scheduling for HEMS, community based optimization has not been the focus. This paper presents an algorithm that targets the minimization of energy costs of whole community while keeping a low Peak to Average Ratio (PAR and smooth Power Usage Pattern (PUP. Objective of cost reduction is accomplished by finding most favorable AAT by Particle Swarm Optimization (PSO in conjunction with Inclined Block Rate (IBR approach and Circular Price Shift (CPS. Simulated numerical results demonstrate the effectiveness of CPS to assist the merger of PSO & IBR to enhance the reduction/stability of PAR and cost reduction.

2010-05-14

The immunogenicity of an intranasally-administered modified-live virus (MLV) vaccine in 3-8 day old calves was evaluated against bovine viral diarrhea virus (BVDV) types 1 and 2, infectious bovine rhinotracheitis (IBR) virus, parainfluenza-3 (PI-3) virus and bovine respiratory syncytial virus (BRSV). Calves were intranasally vaccinated with a single dose of a multivalent MLV vaccine and were challenged with one of the respective viruses three to four weeks post-vaccination in five separate studies. There was significant sparing of diseases in calves intranasally vaccinated with the MLV vaccine, as indicated by significantly fewer clinical signs, lower rectal temperatures, reduced viral shedding, greater white blood cell and platelet counts, and less severe pulmonary lesions than control animals. This was the first MLV combination vaccine to demonstrate efficacy against BVDV types 1 and 2, IBR, PI-3 and BRSV in calves 3-8 days of age. Copyright 2010 Elsevier Ltd. All rights reserved.

Pathogenicity of local isolate virus BHV-1 as the aetiological agent of Infectious Bovine Rhinotracheitis in Bali Cattle

Directory of Open Access Journals (Sweden)

Rini I Damayanti

2005-10-01

Full Text Available Infectious Bovine Rhinotracheitis is a disease of cattle characterised by clinical signs of the upper respiratory tract, reproductive tract and nervous system. A study to define the pathogenicity of four BHV-1 local isolates has been conducted. Fourteen Bali cattle that were free of BHV-1 has been selected and divided into four treatment groups. Each group of three was infected with virus isolate I, II, III and IV respectively with approximately a dose of 108TCID50 /10 ml and two cattle were used as control animals. Isolate I and III were originated from semen from IBR positive bulls number G 867 and G 148 respectively whereas isolate II was collected from vaginal mucosa and isolate IV was from nasal mucosa of IBR positive cattle treated with dexamethasone. Clinical response, gross-pathological and histopathological changes were observed. Immunohistochemical staining was applied to detect the antigen in tissue section. The results show that the BHV-1 local isolates could produce IBR syndrome namely fever and changes in the respiratory and reproductive tracts even though the clinical responses seemed to be disappeared by 21 days PI. Grossly there were hyperaemic nasal and vaginal mucosa and pneumonia whereas histologically there were non suppurative rhinitis, tracheitis, pneumonia and vulvovaginitis. Immunohistochemically the antigen was detected in the nasal concha and trachea. Dexamethasone treatment at 60-64 days PI could produce less severe clinical features and the second necroppsy at 69 days PI also results in less severe pathological responses. The findings also suggest that the pathogenicity of BHV-1 local isolates were as follows: isolates I, II, IV and III.

Crítica das forças produtivas: guerra, destruição ecológica e criação do mundo pós-natural.

Directory of Open Access Journals (Sweden)

André Villar Gomez

2012-09-01

Full Text Available As forças produtivas são uma categoria capitalista e materializam a abstração social baseada no valor. Tal como o processo de valorização, as forças produtivas se desenvolvem sem levar em consideração a satisfação das necessidades humanas e as consequências ecológicas. A produção destrutiva por meio da redução da taxa de utilização dos produtos e os gastos militares crescentes demonstram que o capitalismo passou a destruir riqueza material em larga escala para adequar seus potenciais destrutivos aos estreitos limites de sua forma de riqueza baseada no trabalho abstrato. A aceleração do consumo do mundo, que é uma das manifestações do desenvolvimento tecnológico capitalista, é uma das causas mais importantes da crise ecológica contemporâneia. O mundo pós-natural  consiste na tentativa desmedida e irracional de o capitalismo fugir das "barreiras naturais". A superação da forma social baseada no valor e das forças produtivas tornou-se uma necessidade de primeira ordem.

Dichloroacetonitrile (DCAN) is a typical nitrogenous disinfection by-product (N-DBP) and its toxicity on aquatic animals is investigated for the first time. The present study was designed to investigate the potential adverse effects of DCAN on zebrafish. DCAN could induce developmental toxicity to zebrafish embryos. A significant decrease in hatchability and an increase in malformation and mortality occurred when DCAN concentration was above 100µg/L. Heart function alteration and neuronal function disturbance occurred at concentration higher than 500 and 100µg/L, respectively. Further, DCAN was easily accumulated in adult zebrafish. The rank order of declining bioconcentration factor (BCF) was liver (1240-1670)> gill (1210-1430)> muscle (644-877). DCAN caused acute metabolism damage to adult zebrafish especially at 8 days exposure, at which time the "Integrated Biomarker Response" (IBR) index value reached 798 at 1mg/L DCAN dose. Acute DNA damage was induced to adult zebrafish by DCAN even at 10µg/L dose. Copyright © 2016 Elsevier Inc. All rights reserved.

Mensuração da velocidade de deslocamento de corpos rígidos em tempo real por análise de sequência de imagens e pela transformação empírica baseada nas funções racionais

Danilo Filitto

2014-04-01

Full Text Available Este trabalho apresenta uma metodologia voltada para mensurar a velocidade de um corpo rígido em movimento, tendo como ponto de partida, uma sequência de imagens obtidas por meio de uma filmadora digital. No processo de mensuração da velocidade, na etapa de identificação dos corpos em movimento, é utilizada uma técnica de segmentação baseada na média temporal dos valores de cada pixel registrados em N quadros de imagens consecutivos, em que, após a identificação desses corpos, é realizada a transformação dos pontos no plano imagem para o espaço objeto, por meio do modelo matemático definido como funções racionais. Conhecendo-se as coordenadas dos pontos no espaço objeto, a velocidade de deslocamento do corpo pode ser calculada, através do intervalo de tempo obtido pela quantidade de quadros que a câmara captura por segundo. Para validar a metodologia proposta foi realizado um experimento que contou com a utilização de um aparelho denominado trilho de ar, cinco sensores fotoelétricos dispersos sobre o mesmo com distancias conhecidas entre si e um cronômetro ligado aos sensores. No momento em que um corpo em movimento passa por um sensor, o cronômetro é paralisado e com isso, se tem a distância percorrida pelo corpo entre cada sensor e, quanto tempo foi necessário para percorrer cada uma dessas distâncias. Com esses dados em mãos é realizada uma comparação dos resultados obtidos por meio da análise de sequência de imagens com os resultados obtidos através dos cronômetros e dos sensores fotoelétricos.

Full Text Available Foi constatado um contraste entre as práticas de educação em saúde e a reflexão teórica sobre as mesmas (modelos. Enquanto as primeiras têm tido um desenvolvimento considerável em estratégias, metodologias e modalidades, a segunda permanece reducionista, fragmentadora e atrelada à psicologia comportamentalista. Apontam-se como maiores problemas de tais modelos o individualismo, a alteridade nas relações educador-educando, a passividade do educando, a falta de contextualidade macrossocial e cultural, bem como a ênfase em comportamentos. Propõe-se uma práxis baseada em dez níveis de integração de dimensões múltiplas do ser humano: 1 a complexidade dos objetos requer interdisciplinaridade; 2 concepção holística; 3 integração das duas dimensões de percepção (vivência e expressão (ação em uma linguagem integral; 4 inserção da prática em contextos reais; 5 constatação do continuum indivíduo-coletivo; 6 educação simétrica, dialogal e ativa; 7 integração de processos intelectuais-cognitivos e afetivo-volitivos; 8 visão de riscos como vulnerabilidades de coletivos capazes de iniciativa e organização; 9 visão lúdica que inclui o real imaginado nos jogos de papéis; 10 contemplação do outro e da diversidade.

Full Text Available Resumo Fundamentação: desde o primeiro posicionamento da Sociedade Brasileira de Diabetes (SBD sobre diabetes e prevenção cardiovascular, em 2014,1 importantes estudos têm sido publicados na área de prevenção cardiovascular e tratamento do diabetes,2 os quais contribuíram para a evolução na prevenção primária e secundária nos pacientes com diabetes. Ferramentas de estratificação de risco mais precisas, novos fármacos hipolipemiantes e novos antidiabéticos com efeitos cardiovasculares e redução da mortalidade, são parte desta nova abordagem para os pacientes com diabetes. O reconhecimento de que o diabetes é uma doença heterogênea foi fundamental, sendo claramente demonstrado que nem todos os pacientes diabéticos pertencem a categorias de risco alto ou muito alto. Um porcentual elevado é composto por pacientes jovens, sem os fatores de risco clássicos, os quais podem ser classificados adequadamente em categorias de risco intermediário ou mesmo em baixo risco cardiovascular. O presente posicionamento revisa as melhores evidências atualmente disponíveis e propõe uma abordagem prática, baseada em risco, para o tratamento de pacientes com diabetes. Estruturação: perante este desafio e reconhecendo a natureza multifacetada da doença, a SBD uniu-se à Sociedade Brasileira de Cardiologia (SBC e à Sociedade Brasileira de Endocrinologia e Metabolismo (SBEM, e formou um painel de especialistas, constituído por 28 cardiologistas e endocrinologistas, para revisar as melhores evidências disponíveis e elaborar uma diretriz contendo recomendações práticas para a estratificação de risco e prevenção da Doença Cardiovascular (DVC no Diabetes Melito (DM.

Integrative psychotherapy.

Science.gov (United States)

Kozarić-Kovacić, Dragica

2008-09-01

The main purposes of the article are to present the history of integration in psychotherapy, the reasons of the development integrative approaches, and the approaches to integration in psychotherapy. Three approaches to integration in psychotherapy exist: theoretical integration, theoretical eclecticism, and common factors in different psychotherapeutic trends. In integrative psychotherapy, the basic epistemology, theory, and clinical practice are based on the phenomenology, field theory, holism, dialogue, and co-creation of dialogue in the therapeutic relationship. The main criticism is that integrative psychotherapy suffers from confusion and many unresolved controversies. It is difficult to theoretically and methodologically define the clinically applied model that is based on such a different epistemological and theoretical presumptions. Integrative psychotherapy is a synthesis of humanistic psychotherapy, object relations theory, and psychoanalytical self psychology. It focuses on the dynamics and potentials of human relationships, with a goal of changing the relations and understanding internal and external resistances. The process of integrative psychotherapy is primarily focused on the developmental-relational model and co-creation of psychotherapeutic relationship as a single interactive event, which is not unilateral, but rather a joint endeavor by both the therapist and the patient/client. The need for a relationship is an important human need and represents a process of attunement that occurs as a response to the need for a relationship, a unique interpersonal contact between two people. If this need is not met, it manifests with the different feelings and various defenses. To meet this need, we need to have another person with whom we can establish a sensitive, attuned relationship. Thus, the therapist becomes this person who tries to supplement what the person did not receive. Neuroscience can be a source of integration through different therapies. We

Skin-Reducing Mastectomy in Immediate Reconstruction: How to Limit Complications and Failures.

Science.gov (United States)

Pechevy, Lolita; Carloni, Raphael; Guerid, Samia; Vincent, Pierre-Luc; Toussoun, Gilles; Delay, Emmanuel

2017-06-01

In hypertrophic and/or very ptotic breasts, skin-reducing mastectomy (SRM) is challenging and the risk of complications is high. Few publications have reported the use of an autologous latissimus dorsi flap (ALDF) in this indication. Most studies opt for implant reconstructions, with a high failure rate. We aimed to identify and present the technical refinements that reduce the risk of reconstruction failure in patients with hypertrophic and/or ptotic breasts with breast cancer or at risk of breast cancer after SRM with immediate breast reconstruction (IBR) utilizing an ALDF. Our retrospective study, covering a period of 18 years, included a series of 60 patients with hypertrophic and/or ptotic breasts who underwent 67 SRM and IBR procedures utilizing an ALDF. The complications were recorded and the risk factors analyzed. Sixty-seven SRMs were reviewed. Forty-nine procedures were performed with an inverted-T scar technique and 18 with a vertical scar technique. The nipple-areola complex (NAC) was preserved in 10 cases. There were eight (11.9%) cases of minor mastectomy flap necrosis after skin-reducing reconstructions, 16 (23.8%) wound dehiscences, no infections, no breast seromas, and no reconstruction failures. Smoking increased the risk of minor mastectomy flap necrosis (P = 0.048) and wound dehiscence (P = 0.002). Previous radiotherapy was associated with minor mastectomy flap necrosis (P = 0.001). The use of an ALDF together with technical refinements that preserve the vascular supply of the skin envelope leads to successful IBR with consistently good aesthetic results. Above all, it avoids failure of the reconstruction in very large or ptotic breasts. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Trends in breast reconstruction: Implications for the National Health Insurance Service

Directory of Open Access Journals (Sweden)

Ki Yong Hong

2018-05-01

Full Text Available Background Breast reconstruction has become more common as mastectomy has become more frequent. In Korea, the National Health Insurance Service (NHIS began covering breast reconstruction in April 2015. This study aimed to investigate trends in mastectomy and breast reconstruction over the past 10 years and to evaluate the impact of NHIS coverage on breast reconstruction. Methods Nationwide data regarding mastectomy and breast reconstruction were collected from the Korean Breast Cancer Society registry database. Multiple variables were analyzed in the records of patients who underwent breast reconstruction from January 2005 to March 2017 at a single institution. Results At Seoul National University Hospital, the total number of reconstruction cases increased 13-fold from 2005 to 2016. The proportion of immediate breast reconstruction (IBR cases out of all cases of total mastectomy increased from 4% in 2005 to 52.0% in 2016. The proportion of delayed breast reconstruction (DBR cases out of all cases of breast reconstruction and the overall number of DBR cases increased from 8.8% (20 cases in 2012 to 18.3% (76 cases in 2016. After NHIS coverage was initiated, the proportions of IBR and DBR showed statistically significant increases (P<0.05. Among the IBR cases, the percentage of prosthesis-based reconstructions increased significantly (P<0.05, but this trend was not found with DBR. Total mastectomy became significantly more common after the expansion of NHIS coverage (P<0.05. Conclusions Over the last decade, there has been an increase in mastectomy and breast reconstruction, and the pace of increase accelerated after the expansion of NHIS coverage. It is expected that breast reconstruction will be a routine option for patients with breast cancer under the NHIS.

Evaluation of cross sections of Th-232 and U-233

International Nuclear Information System (INIS)

Dias, A.M.

1978-01-01

The cross sections in multigroups of Th-232 and U-233 are evaluated by comparison of theoretical results and experimental data obtained through experiments on the fast reactors IBR-I, EBR-II, BR-I and AETR. The deviation between calculated values and experimental results is about 10%. They are therefore satisfatory for neutronic calculations [pt

RBCC protein interacting with PKC 1 (RBCK1) is a transcription factor belonging to the RING-IBR protein family and has been shown to shuttle between the nucleus and cytoplasm, possessing both the nuclear export and localization signals within its amino acid sequence. RBCK2, lacking the C-terminal half of RBCK1 including the RING-IBR domain, has also been identified as an alternative splice variant of RBCK1. RBCK2 shows no transcriptional activity and instead it represses the transcriptional activity of RBCK1. Here, we show that RBCK2 is present usually in the cytoplasm containing two Leu-rich regions that presumably serve as a nuclear export signal (NES). Moreover, an NES-disrupted RBCK1 that is mostly localized within the nucleus is translocated to the cytoplasm when coexpressed with RBCK2, suggesting that RBCK2 serves as a cytoplasmic tethering protein for RBCK1. We propose a novel and general function of RING-lacking splice variants of RING proteins to control the intracellular localization and functions of the parental RING proteins by forming a hetero-oligomeric complex

Genetic and Environmental Contributions to Behavioral Stability and Change in Children 6-36 months of Age Using Louisville Twin Study Data.

The Infant Behavior Record (IBR) from the Bayley Scales of Infant Development has been used to study behavioral development since the 1960s. Matheny (1983) examined behavioral development at 6, 12, 18, and 24 months from the Louisville Twin Study (LTS). The extracted temperament scales included Task Orientation, Affect-Extraversion, and Activity. He concluded that monozygotic twins were more similar than same-sex dizygotic twins on these dimensions. Since this seminal work was published, a larger LTS sample and more advanced analytical methods are available. In the current analyses, Choleksy decomposition was applied to behavioral data (n = 1231) from twins 6-36 months. Different patterns of genetic continuity vs genetic innovations were identified for each IBR scale. Single common genetic and shared environmental factors explained cross-age twin similarity in the Activity scale. Multiple shared environmental factors and a single genetic factor coming on line at age 18 months contributed to Affect-Extraversion. A single shared environmental factor and multiple genetic factors explained cross-age twin similarity in Task Orientation.

A principally new diagnostic method must be developed for magnetic measurements in steady state regime of operation of fusion reactor. One of the options is the use of transducers based on Hall effect. The use of Hall sensors in ITER is presently limited by their questionable radiation and thermal stability. Issues of reliable operation in ITER like radiation and thermal environment are addressed in the paper. The results of irradiation tests of candidate Hall sensors in LVR-15 and IBR-2 experimental fission reactors are presented. Stable operation (deterioration of sensitivity below one percent) of the specially prepared sensors was demonstrated during irradiation by the total fluence of 3.10 16 n/cm 2 in IBR-2 reactor. Increasing the total neutron fluence up to 3.10 17 n/cm 2 resulted in deterioration of the best sensor's output still below 10% as demonstrated during irradiation in LVR-15 fission reactor. This level of neutron is already higher than the expected ITER life time neutron fluence for a sensor location just outside the ITER vessel. (authors)

Systems integration.

Science.gov (United States)

Siemieniuch, C E; Sinclair, M A

2006-01-01

The paper presents a view of systems integration, from an ergonomics/human factors perspective, emphasising the process of systems integration as is carried out by humans. The first section discusses some of the fundamental issues in systems integration, such as the significance of systems boundaries, systems lifecycle and systems entropy, issues arising from complexity, the implications of systems immortality, and so on. The next section outlines various generic processes for executing systems integration, to act as guides for practitioners. These address both the design of the system to be integrated and the preparation of the wider system in which the integration will occur. Then the next section outlines some of the human-specific issues that would need to be addressed in such processes; for example, indeterminacy and incompleteness, the prediction of human reliability, workload issues, extended situation awareness, and knowledge lifecycle management. For all of these, suggestions and further readings are proposed. Finally, the conclusions section reiterates in condensed form the major issues arising from the above.

Improving integration for integrated coastal zone management: an eight country study.

Portman, M E; Esteves, L S; Le, X Q; Khan, A Z

2012-11-15

Integrated coastal zone management (ICZM) is a widely accepted approach for sustainable management of the coastal environment. ICZM emphasizes integration across sectors, levels of government, uses, stakeholders, and spatial and temporal scales. While improving integration is central to progress in ICZM, the role of and the achievement of integration remain understudied. To further study these two points, our research analyzes the performance of specific mechanisms used to support ICZM in eight countries (Belgium, India, Israel, Italy, Portugal, Sweden, UK, and Vietnam). The assessment is based on a qualitative comparative analysis conducted through the use of two surveys. It focuses on five ICZM mechanisms (environmental impact assessment; planning hierarchy; setback lines; marine spatial planning, and regulatory commission) and their role in improving integration. Our findings indicate that certain mechanisms enhance specific types of integration more effectively than others. Environmental impact assessment enhances science-policy integration and can be useful to integrate knowledge across sectors. Planning hierarchy and regulatory commissions are effective mechanisms to integrate policies across government levels, with the latter also promoting public-government integration. Setback lines can be applied to enhance integration across landscape units. Marine spatial planning is a multi-faceted mechanism with the potential to promote all types of integration. Policy-makers should adopt the mechanisms that are suited to the type of integration needed. Results of this study also contribute to evidence-based coastal management by identifying the most common impediments related to the mechanisms of integration in the eight studied countries.

Two distinct but related approaches hold the solutions to many mathematical problems--the forms of expression known as differential and integral equations. The method employed by the integral equation approach specifically includes the boundary conditions, which confers a valuable advantage. In addition, the integral equation approach leads naturally to the solution of the problem--under suitable conditions--in the form of an infinite series.Geared toward upper-level undergraduate students, this text focuses chiefly upon linear integral equations. It begins with a straightforward account, acco

Measuring the degree of integration for an integrated service network

Directory of Open Access Journals (Sweden)

Chenglin Ye

2012-09-01

Full Text Available Background: Integration involves the coordination of services provided by autonomous agencies and improves the organization and delivery of multiple services for target patients. Current measures generally do not distinguish between agencies' perception and expectation. We propose a method for quantifying the agencies' service integration. Using the data from the Children's Treatment Network (CTN, we aimed to measure the degree of integration for the CTN agencies in York and Simcoe.  Theory and Methods: We quantified the integration by the agreement between perceived and expected levels of involvement and calculated four scores from different perspectives for each agency. We used the average score to measure the global network integration and examined the sensitivity of the global score.  Results: Most agencies' integration scores were less than 65%. As measured by the agreement between every other agency's perception and expectation, the overall integration of CTN in Simcoe and York was 44% (95% CI: 39% - 49% and 52% (95% CI: 48% - 56%, respectively. The sensitivity analysis showed that the global scores were robust.  Conclusion: Our method extends existing measures of integration and possesses a good extent of validity. We can also apply the method in monitoring improvement and linking integration with other outcomes.

This paper aims to contribute to a theory of integration within the field of IS project management. Integration is a key IS project management issue when new systems are developed and implemented into an increasingly integrated information infrastructure in corporate and governmental organizations....... Expanding the perspective of traditional project management research, we draw extensively on central insights from IS research. Building on socio-technical IS research and Software Engineering research we suggest four generic patterns of integration: Big Bang, Stakeholder Integration, Technical Integration...... and Socio-Technical Integration. We analyze and describe the advantages and disadvantages of each pattern. The four patterns are ideal types. To explore the forces and challenges in these patterns three longitudinal case studies were conducted. In particular we investigate the management challenges for each...

Relationships between metal compartmentalization and biomarkers in earthworms exposed to field-contaminated soils.

Partitioning tissue metal concentration into subcellular compartments reflecting toxicologically available pools may provide good descriptors of the toxicological effects of metals on organisms. Here we investigated the relationships between internal compartmentalization of Cd, Pb and Zn and biomarker responses in a model soil organism: the earthworm. The aim of this study was to identify metal fractions reflecting the toxic pressure in an endogeic, naturally occurring earthworm species (Aporrectodea caliginosa) exposed to realistic field-contaminated soils. After a 21 days exposure experiment to 31 field-contaminated soils, Cd, Pb and Zn concentrations in earthworms and in three subcellular fractions (cytosol, debris and granules) were quantified. Different biomarkers were measured: the expression of a metallothionein gene (mt), the activity of catalase (CAT) and of glutathione-s-transferase (GST), and the protein, lipid and glycogen reserves. Biomarkers were further combined into an integrated biomarker index (IBR). The subcellular fractionation provided better predictors of biomarkers than the total internal contents hence supporting its use when assessing toxicological bioavailability of metals to earthworms. The most soluble internal pools of metals were not always the best predictors of biomarker responses. metallothionein expression responded to increasing concentrations of Cd in the insoluble fraction (debris + granules). Protein and glycogen contents were also mainly related to Cd and Pb in the insoluble fraction. On the other hand, GST activity was better explained by Pb in the cytosolic fraction. CAT activity and lipid contents variations were not related to metal subcellular distribution. The IBR was best explained by both soluble and insoluble fractions of Pb and Cd. This study further extends the scope of mt expression as a robust and specific biomarker in an ecologically representative earthworm species exposed to field-contaminated soils. The

Integrated science learning has various types of integration. This study aims to apply shared and integrated type of integration with project based learning (PjBL) model to improve students’ creativity on waste recycling theme. The research method used is a quasi experiment with the matching-only pre test-post test design. The samples of this study are 108 students consisting of 36 students (experiment class 1st), 35 students (experiment class 2nd) and 37 students (control class 3rd) at one of Junior High School in Tanggamus, Lampung. The results show that there is difference of creativity improvement in the class applied by PjBL model with shared type of integration, integrated type of integration and without any integration in waste recycling theme. Class applied by PjBL model with shared type of integration has the higher creativity improvement than the PjBL model with integrated type of integration and without any integration. Integrated science learning using shared type only combines 2 lessons, hence an intact concept is resulted. So, PjBL model with shared type of integration more effective improves students’ creativity than integrated type.

Retroviral DNA Integration Directed by HIV Integration Protein in Vitro

Science.gov (United States)

Bushman, Frederic D.; Fujiwara, Tamio; Craigie, Robert

1990-09-01

Efficient retroviral growth requires integration of a DNA copy of the viral RNA genome into a chromosome of the host. As a first step in analyzing the mechanism of integration of human immunodeficiency virus (HIV) DNA, a cell-free system was established that models the integration reaction. The in vitro system depends on the HIV integration (IN) protein, which was partially purified from insect cells engineered to express IN protein in large quantities. Integration was detected in a biological assay that scores the insertion of a linear DNA containing HIV terminal sequences into a λ DNA target. Some integration products generated in this assay contained five-base pair duplications of the target DNA at the recombination junctions, a characteristic of HIV integration in vivo; the remaining products contained aberrant junctional sequences that may have been produced in a variation of the normal reaction. These results indicate that HIV IN protein is the only viral protein required to insert model HIV DNA sequences into a target DNA in vitro.

Background: In Sweden, as in many other countries, there has been a succession of trends in the organisation of health care and other welfare services. These trends have had different implications for the integration of services in the health and welfare system. Aims: One aim is to discuss...... the implications of different organisational trends for the integration of health and welfare services. Another aim is to introduce a Swedish model of financial coordination as a flexible way to organise integration. Organisational trends: In the 1960’s there was an expansion of health and welfare services leading...... an increasing lack of integration in the health and welfare system. In the 2000’s, there has been a re-centralisation through mergers of hospitals, regions and state agencies. It has become clear, however, that mergers do not promote integration but rather increase the bureaucratisation of the system. Model...

At the Laboratory of Neutron Physics (JINR, Dubna) the new polarized neutron spectrometer REMUR has been constructed and commissioned. The spectrometer REMUR is dedicated to investigations of multilayers and surfaces by polarized neutron reflection and of the inhomogeneous state of solids by diffuse small-angle polarized neutron scattering. The spectrometer operates in the neutron wavelength interval 1-10 Angstroem. In the reflectometry mode it allows one to complete polarization analysis and neutron position-sensitive detection within the solid angle of scattering 2.2·10 -4 rad. The spectrometer ensures good statistics of the reflectometric data in the scattering wave vector interval 3·10 -3 - 5·10 -1 Angstroem -1 . In the small-angle scattering mode the spectrometer allows the investigation of neutron scattering processes without spin-flip over the detector's neutron registration solid angle interval from 4·10 -3 to 10 -1 rad and the scattering wave vector interval from 0.006-0.15 to 0.03-0.7 Angstroem -1 , respectively

Integrated photonics generally is the integration of multiple lithographically defined photonic and electronic components and devices (e.g. lasers, detectors, waveguides passive structures, modulators, electronic control and optical interconnects) on a single platform with nanometer-scale feature sizes. The development of photonic integrated circuits permits size, weight, power and cost reductions for spacecraft microprocessors, optical communication, processor buses, advanced data processing, and integrated optic science instrument optical systems, subsystems and components. This is particularly critical for small spacecraft platforms. We will give an overview of some NASA applications for integrated photonics.

Automatic numerical integration methods for Feynman integrals through 3-loop

International Nuclear Information System (INIS)

De Doncker, E; Olagbemi, O; Yuasa, F; Ishikawa, T; Kato, K

2015-01-01

We give numerical integration results for Feynman loop diagrams through 3-loop such as those covered by Laporta [1]. The methods are based on automatic adaptive integration, using iterated integration and extrapolation with programs from the QUADPACK package, or multivariate techniques from the ParInt package. The Dqags algorithm from QuadPack accommodates boundary singularities of fairly general types. PARINT is a package for multivariate integration layered over MPI (Message Passing Interface), which runs on clusters and incorporates advanced parallel/distributed techniques such as load balancing among processes that may be distributed over a network of nodes. Results are included for 3-loop self-energy diagrams without IR (infra-red) or UV (ultra-violet) singularities. A procedure based on iterated integration and extrapolation yields a novel method of numerical regularization for integrals with UV terms, and is applied to a set of 2-loop self-energy diagrams with UV singularities.

Only such system, being integral, may, firstly, become the basis for the formation of an integrative law of this integration project, and secondly, have a supranational constitutionality, giving the ability to individual enforcement.Purpose. The purpose of this paper is the design of the constitutional-legal mechanisms of international integration in the scope of an integrative understanding of law and law enforcement.Methodology. The author uses methods of theoretical analysis, particularly the theory of integrative legal consciousness, as well as legal methods, including formal legal method and comparative law.Results, scope of application. The author points out that the formation of a single legal space in the Eurasian Economic Union (EEU, as well as in Customs Union and the Eurasian Economic Community before, is a development of constitutional law of supranational level, not of international law. The integration of law and integrality of the legislation are prerequisite for the success of the interstate Eurasian integration.Integration of law means the completeness of its internal structure, implies the indissoluble inner coherence of the law, its wholeness, unity. Coherent legal norms, embodied in legislation, can only create the phenomenon of law. The law should be understood as a metasystem, supersystem, it accumulates all socially significant systems and integrates the values of the law itself, its principles, values, other social regulators and regulated spheres of social relations. Attempts to apply the concept of "integration", but to abandon the notion of "integrality" are unreasonable, this terminological dichotomy is just a word game.If we talk about law, it is more appropriate to talk about it’s iintegrity, but if we talk about legislation, emerging to accelerate and deepen integration

Exact Slater integrals

International Nuclear Information System (INIS)

Golden, L.B.

1968-01-01

In atomic structure calculations, one has to evaluate the Slater integrals. In the present program, the authors evaluate exactly the Slater integral when hydrogenic wave functions are used for the bound-state orbitals. When hydrogenic wave functions are used, the Slater integrals involve integrands which can be written in the form of a product of an exponential, exp(ax) and a known analytic polynomial function, f(x). By repeated partial integration such an integral can be expressed in terms of a finite series involving the exponential, the polynomial function and its derivatives. PL/1-FORMAC has a built-in subroutine that will analytically find the derivatives of any multinomial. Thus, the finite series and hence the Slater integral can be evaluated analytically. (Auth.)

Integrated cryogenic pressure-temperature, level-temperature, and flow-temperature sensors have several advantages over the conventional single parameter sensors. Such integrated sensors were not available until recently. Pressure Systems, Inc. (PSI) of Hampton, Virginia, has introduced precalibrated precision cryogenic pressure sensors at the Los Angeles Cryogenic Engineering Conference in 1989. Recently, PSI has successfully completed the development of integrated pressure-temperature and level-temperature sensors for use in the temperature range 1.5-375K. In this paper, performance characteristics of these integrated sensors are presented. Further, the effects of irradiation and magnetic fields on these integrated sensors are also reviewed

Integration by cell algorithm for Slater integrals in a spline basis

International Nuclear Information System (INIS)

Qiu, Y.; Fischer, C.F.

1999-01-01

An algorithm for evaluating Slater integrals in a B-spline basis is introduced. Based on the piecewise property of the B-splines, the algorithm divides the two-dimensional (r 1 , r 2 ) region into a number of rectangular cells according to the chosen grid and implements the two-dimensional integration over each individual cell using Gaussian quadrature. Over the off-diagonal cells, the integrands are separable so that each two-dimensional cell-integral is reduced to a product of two one-dimensional integrals. Furthermore, the scaling invariance of the B-splines in the logarithmic region of the chosen grid is fully exploited such that only some of the cell integrations need to be implemented. The values of given Slater integrals are obtained by assembling the cell integrals. This algorithm significantly improves the efficiency and accuracy of the traditional method that relies on the solution of differential equations and renders the B-spline method more effective when applied to multi-electron atomic systems

Integrated assessment briefs

NONE

1995-04-01

Integrated assessment can be used to evaluate and clarify resource management policy options and outcomes for decision makers. The defining characteristics of integrated assessment are (1) focus on providing information and analysis that can be understood and used by decision makers rather than for merely advancing understanding and (2) its multidisciplinary approach, using methods, styles of study, and considerations from a broader variety of technical areas than would typically characterize studies produced from a single disciplinary standpoint. Integrated assessment may combine scientific, social, economic, health, and environmental data and models. Integrated assessment requires bridging the gap between science and policy considerations. Because not everything can be valued using a single metric, such as a dollar value, the integrated assessment process also involves evaluating trade-offs among dissimilar attributes. Scientists at Oak Ridge National Laboratory (ORNL) recognized the importance and value of multidisciplinary approaches to solving environmental problems early on and have pioneered the development of tools and methods for integrated assessment over the past three decades. Major examples of ORNL`s experience in the development of its capabilities for integrated assessment are given.

Chang, Moon Hee; Kang, D. J.; Kim, K. K. and others

1999-03-01

The objective of this report is to integrate the conceptual design of an integral reactor, SMART producing thermal energy of 330 MW, which will be utilized to supply energy for seawater desalination and small-scale power generation. This project also aims to develop system integration technology for effective design of the reactor. For the conceptual design of SMART, preliminary design requirements including the top-tier requirements and design bases were evaluated and established. Furthermore, in the view of the application of codes and standards to the SMART design, existing laws, codes and standards were analyzed and evaluated with respect to its applicability. As a part of this evaluation, directions and guidelines were proposed for the development of new codes and standards which shall be applied to the SMART design. Regarding the integration of SMART conceptual designs, major design activities and interfaces between design departments were established and coordinated through the design process. For the effective management of all design schedules, a work performance evaluation system was developed and applied to the design process. As the results of this activity, an integrated output of SMART designs was produced. Two additional scopes performed in this project include the preliminary economic analysis on the SMART utilization for seawater desalination, and the planning of verification tests for technology implemented into SMART and establishing development plan of the computer codes to be used for SMART design in the next phase. The technical cooperation with foreign country and international organization for securing technologies for integral reactor design and its application was coordinated and managed through this project.

1988-01-01

The concept of Boolean integration is developed, and different Boolean integral operators are introduced. Given the changes in a desired function in terms of the changes in its arguments, the ways of 'integrating' (i.e. realizing) such a function, if it exists, are presented. The necessary and sufficient conditions for integrating, in different senses, the expression specifying the changes are obtained. Boolean calculus has applications in the design of logic circuits and in fault analysis.

Does energy integrate?

2003-01-01

Amidst the international movement to privatize and deregulate electricity and gas sectors of economies, the question of the integration of those sectors has been somewhat underestimated. In fact, the integration of energy markets across boundaries is occurring. We examine this process in three regions: Europe, Central America, and South America. We analyze the forces driving integration in each area, and estimate the prospects for progress. We take a close look at Nordpool, which is now the most integrated market in the world, to see if it can serve as a model for other regions. We close with a set of conditions that we suggest are necessary for a successful international integration of energy markets

We resolve inconsistencies between integration in four dimensions, where shifts of integration variable may lead to surface terms, and dimensional regularization, where no surface terms accompany such shifts, by showing that surface terms arise only for discrete values of the dimension parameter. General formulas for variable-of-integration shifts within N-dimensional Feynman integrals are presented, and the VVA triangle anomaly is interpreted as a manifestation of surface terms occurring in exactly four dimensions

A Liouville integrable hierarchy, symmetry constraint, new finite-dimensional integrable systems, involutive solution and expanding integrable models

International Nuclear Information System (INIS)

2006-01-01

A new spectral problem and the associated integrable hierarchy of nonlinear evolution equations are presented in this paper. It is shown that the hierarchy is completely integrable in the Liouville sense and possesses bi-Hamiltonian structure. An explicit symmetry constraint is proposed for the Lax pairs and the adjoint Lax pairs of the hierarchy. Moreover, the corresponding Lax pairs and adjoint Lax pairs are nonlinearized into a hierarchy of commutative, new finite-dimensional completely integrable Hamiltonian systems in the Liouville sense. Further, an involutive representation of solution of each equation in the hierarchy is given. Finally, expanding integrable models of the hierarchy are constructed by using a new Loop algebra

The fear of speaking is often cited as the world's most common social phobia. The rapid growth of computer technology enabled us to use virtual reality (VR) for the treatment of the fear of public speaking. There have been two techniques used to construct a virtual environment for the treatment of the fear of public speaking: model-based and movie-based. Virtual audiences and virtual environments made by model-based technique are unrealistic and unnatural. The movie-based technique has a disadvantage in that each virtual audience cannot be controlled respectively, because all virtual audiences are included in one moving picture file. To address this disadvantage, this paper presents a virtual environment made by using image-based rendering (IBR) and chroma keying simultaneously. IBR enables us to make the virtual environment realistic because the images are stitched panoramically with the photos taken from a digital camera. And the use of chroma keying allows a virtual audience to be controlled individually. In addition, a real-time capture technique was applied in constructing the virtual environment to give the subjects more interaction, in that they can talk with a therapist or another subject.

An exposure experiment was conducted to study the effect of different volume fraction of effluent streptomycin wastewater on the activity of the peroxidase (POD) activity and the malondialdehyde (MDA) content in muscles of Zebrafish for 20 days. The results show that POD activity is significantly induced on the eighth day. POD activities in the muscles of Zebrafish exposed to the streptomycin wastewater of 20% exposure group were significantly different (0.01IBR) increase at first and then decrease. The IBR value of Zebrafish that exposed streptomycin wastewater ranged from 10.42 to 54.26, and the wastewater of 10% exposure group induced the maximum value on the twelve day. The study indicates that low concentration streptomycin wastewater has impacts on the antioxidant defense system and antioxidant ability of Zebrafish.

Objective: To investigate the effect of Kaiyu Qingwei granule (KYQWG,开郁清胃颗粒) on the insulin binding capacity of liver and skeletal muscular cell membrane and serum insulin-like growth factor-1 (IGF-1) in streptozotocin-induced diabetic rats. Methods:Rats in four experimental groups were investigated: the control group, the model group, the KYQWG group and the Metformin group. The insulin binding rate (IBR) of liver and skeletal muscular cell membrane was detected by receptor-ligand radiometric method and changes of serum levels of glucose, insulin and IGF-1 were observed before and after 4 weeks of medication. Results: The KYQWG group had a lower blood glucose level and IBR of liver and muscular cell membrane, as compared with those in the model group (P<0.01 or P<0.05), and a higher level of IGF-1 than that in the model group(P<0.01), but had no obvious changes in the serum level of insulin. Conclusion: KYQWG may increase the serum level of IGF-1 in diabetic rats, thus to decrease the insulin resistance at ante-receptor sites and improve the sugar metabolic disturbance in rats with diabetes mellitus.

Zhang, Weiwei; Jiang, Shengyuan; Ji, Jie; Tang, Dewei

2018-05-01

The physical and mechanical properties as well as the heat flux of regolith are critical evidence in the study of planetary origin and evolution. Moreover, the mechanical properties of planetary regolith have great value for guiding future human planetary activities. For planetary subsurface exploration, an inchworm boring robot (IBR) has been proposed to penetrate the regolith, and the mechanical properties of the regolith are expected to be simultaneously investigated during the penetration process using the drilling tool on the IBR. This paper provides a preliminary study of an in situ method for measuring planetary regolith mechanical parameters using a drilling tool on a test bed. A conical-screw drilling tool was designed, and its drilling load characteristics were experimentally analyzed. Based on the drilling tool-regolith interaction model, two identification methods for determining the planetary regolith bearing and shearing parameters are proposed. The bearing and shearing parameters of lunar regolith simulant were successfully determined according to the pressure-sinkage tests and shear tests conducted on the test bed. The effects of the operating parameters on the identification results were also analyzed. The results indicate a feasible scheme for future planetary subsurface exploration.

Building models of a biological system that are consistent with the myriad data available is one of the key challenges in biology. Modeling the structure and dynamics of macromolecular assemblies, for example, can give insights into how biological systems work, evolved, might be controlled, and even designed. Integrative structure modeling casts the building of structural models as a computational optimization problem, for which information about the assembly is encoded into a scoring function that evaluates candidate models. Here, we describe our open source software suite for integrative structure modeling, Integrative Modeling Platform (https://integrativemodeling.org), and demonstrate its use. © 2017 The Protein Society.

We introduce a generalized Wiener measure associated with a Gaussian Markov process and define a generalized analytic operator-valued function space integral as a bounded linear operator from L p into L p-ci r cumflexprime (1< p ≤ 2) by the analytic continuation of the generalized Wiener integral. We prove the existence of the integral for certain functionals which involve some Borel measures. Also we show that the generalized analytic operator-valued function space integral satisfies an integral equation related to the generalized Schroedinger equation. The resulting theorems extend the theory of operator-valued function space integrals substantially and previous theorems about these integrals are generalized by our results

A current status and a corrected time-schedule of the project of the new Intense Resonance Neutron pulsed source (IREN) realized in JINR (Dubna) for experiments dealing with fundamental and applied nuclear physics studies are discussed. This source is the upgraded variant of the existing IBR-30 pulsed booster. It consists of the 200 MeV electron linac and supplying by an electron beam the photo-neutron converter placed in the center of the very fast multiplying subcritical core. The existing buildings and beam infrastructure are planned to adopt for the new IREN source. The aim of the project is to improve essentially an energy resolution of the time-of-flight spectrometer and to increase twice (up to 10 15 n/sec) an integral neutron yield. An implementation of the IREN project has started in June 1994 with the planned end in December 1997. But due to mainly insufficient financing the approved time-schedule is shifted. Now most optimistic time of start-up of the neutron source is the end of 1999

The reliability and integrity evaluation of structures and equipment on the petroleum and gas industry is an absolute necessary care due to economic reasons and safety. As a consequence, new supporting technologies for well known nondestructive test and evaluation methods have been developed in order to automate these inspection processes, improving their robustness, accuracy and quickness. On this way, the present work introduces solutions to overcome some obstacles to the automation of the radiographic image analysis task for the pipeline weld joint inspection, on radiographic non-destructive tests and evaluations. The main contributions are related to the improvements to techniques for the automatic weld bean segmentation and the development of an effective algorithm for the weld bean defect detection and extraction of relevant defect descriptors.

Full Text Available Background: In the context of integrated care, Multidisciplinary Group (MDG meetings involve participants from diverse professional groups and organizations and are potential vehicles to advance efficiency improvements within the local health economy.  We advance a novel method to evaluate the effectiveness of MDGs by measuring the extent to which participants integrate within MDG meetings and whether this integration leads to improved working. Methods: We purposively selected four MDG meetings, and conducted a content analysis of audio-recorded and transcribed case discussions. Two coders independently coded utterances according to their ‘integrative intensity’ which was defined against three a priori independent domains – the Level (i.e. Individual, Collective and Systems; the Valence (Problem, Information and Solution; the Focus (Concrete and Abstract. Inter- and intra-rater reliability was tested with Kappa scores on one randomly selected Case Discussion.  Standardized weighted mean integration scores were calculated for Case Discussions across utterance deciles, indicating how integrative intensity changed during the conversations. Results: Twenty-three Case Discussions in four different MDG groups were transcribed and coded. Inter- and intra-rater reliability was good as shown by the Prevalence and Bias Adjusted Kappa Scores for one randomly selected Case Discussion.  There were differences in the proportion of utterances per participant type (Consultant 14.6%; Presenting GP 38.75%; Chair 7.8%; Non-Presenting GP 2.25%; Allied Health Professional 4.8%. Utterances were predominantly coded at low levels of integrative intensity; however there was a gradual increase (R2=0.66 in integrative intensity during the Case Discussions.  Based on analysis of the minutes and action points arising from the Case Discussions, this improved integration did not translate into actions moving forward. Interpretation: We characterize the MDGs as

Each person must be appreciated at its true value regardless of its condition of normality or deviation from it. Valuing individuals can be achieved only through a full acceptance in society, by assigning statuses and fulfilling social roles. School integration of children with special educational needs in mainstream education is a challenge and involves many aspects to be successful. It is the premise of social integration, the basis for future socio-professional insertion. Integrated education is the first step towards a world of equal opportunities, a world without discrimination.

By a "box integral" we mean here an expectation $\\langle|\\vec r - \\vec q|^s \\rangle$ where $\\vec r$runs over the unit $n$-cube,with $\\vec q$ and $s$ fixed, explicitly:\\begin eqnarray*&&\\int_01 \\cdots \\int_01 \\left((r_1 - q_1)2 + \\dots+(r_n-q_n)2\\right)^ s/2 \\ dr_1 \\cdots dr_n.\\end eqnarray* The study ofbox integrals leads one naturally into several disparate fields ofanalysis. While previous studies have focused upon symbolic evaluationand asymptotic analysis of special cases (notably $s = 1$), we workherein more generally--in interdisciplinary fashion--developing resultssuch as: (1) analytic continuation (in complex $s$), (2) relevantcombinatorial identities, (3) rapidly converging series, (4) statisticalinferences, (5) connections to mathematical physics, and (6)extreme-precision quadrature techniques appropriate for these integrals.These intuitions and results open up avenues of experimental mathematics,with a view to new conjectures and theorems on integrals of thistype.

Heat exchange process differential equations are considered for a subcritical fuel assembly with an injector. The equations are obtained by means of the use of the Hermit polynomial. The model is created for modelling of temperature transitional processes. The parameters and dynamics are estimated for hypothetical fuel assembly consisting of real mountings: the powerful proton accelerator and the reactor IBR-2 core at its subcritica l state.

Complexing of acetyl derivatives of azoles with iodine and bromine iodide is investigated using UV-spectroscopy and dipole moment methods. In bimolecular complexes σ-acceptor coordination occurs by heterocycle pyridine type nitrogen atom and is not accompanied by the ligand conformation change. The complex stability increases in agreement with azole basicity. For N-acetyltriazole ligand, conformation reversal occurs in its trimolecular complex with IBr

The radiation-induced formation of silver colloid was checked for its use as a sensitive dosimeter for neutron irradiation. For non-monoenergetic pulsed neutron irradiation in the Dubna IBR-30 reactor, the colloid dosimeter was found to be suitable to indicate the chemical neutron effect, i.e., to determine the sum concentration of the primary particles of water radiolysis: esub(aq)sup(-), OH and H.

Four key factors determine the success of integrated services projects: teamwork, common objectives, technology, and shared benefits. For oil companies, integration means smoother, more efficient operations by bringing service companies on board as part of the team. For the service industry, it means a radical change in the way business is conducted, taking on more responsibility in return for greater incentives.

Purpose Services’ integration comprises organizational, normative, economic, informational and clinical dimensions. Since 2004, the province of Quebec has devoted significant efforts to unify the governance of the main health and social care organizations of its various territories. Notwithstanding the uniformity of the national plan’s prescription, the territorial integration modalities greatly vary across the province. Theory This research is based upon a conceptual model of integration that comprises six components: inter-organizational partnership, case management, standardized assessment, a single entry point, a standardized service planning tool and a shared clinical file. Methods We conducted an embedded case study in six contrasted sites in terms of their level of integration. All documents prescribing the implementation of integration were retrieved and analyzed. Results and conclusions The analyzed documents demonstrate a growing local appropriation of the current integrative reform. Interestingly however, no link seems to exist between the quality of local prescriptions and the level of integration achieved in each site. This finding leads us to hypothesize that the variable quality of the operational accompaniment offered to implement these prescriptions is a variable in play.

The Vehicle Integrated Performance Analysis Experience: Reconnecting With Technical Integration

2006-01-01

Very early in the Space Launch Initiative program, a small team of engineers at MSFC proposed a process for performing system-level assessments of a launch vehicle. Aimed primarily at providing insight and making NASA a smart buyer, the Vehicle Integrated Performance Analysis (VIPA) team was created. The difference between the VIPA effort and previous integration attempts is that VIPA a process using experienced people from various disciplines, which focuses them on a technically integrated assessment. The foundations of VIPA s process are described. The VIPA team also recognized the need to target early detailed analysis toward identifying significant systems issues. This process is driven by the T-model for technical integration. VIPA s approach to performing system-level technical integration is discussed in detail. The VIPA process significantly enhances the development and monitoring of realizable project requirements. VIPA s assessment validates the concept s stated performance, identifies significant issues either with the concept or the requirements, and then reintegrates these issues to determine impacts. This process is discussed along with a description of how it may be integrated into a program s insight and review process. The VIPA process has gained favor with both engineering and project organizations for being responsive and insightful

Background Despite 82% of patients reporting psychosocial improvement following breast reconstruction, only 33% patients choose to undergo surgery. Implant reconstruction outnumbers autologous reconstruction in many centres. Methods A systematic review of the literature was undertaken. Inclusion required: (I) Meta-analyses or review articles; (II) adult patients aged 18 years or over undergoing alloplastic breast reconstruction; (III) studies including outcome measures; (IV) case series with more than 10 patients; (V) English language; and (VI) publication after 1st January, 2000. Results After full text review, analysis and data extraction was conducted for a total of 63 articles. Definitive reconstruction with an implant can be immediate or delayed. Older patients have similar or even lower complication rates to younger patients. Complications include capsular contracture, hematoma and infection. Obesity, smoking, large breasts, diabetes and higher grade tumors are associated with increased risk of wound problems and reconstructive failure. Silicone implant patients have higher capsular contracture rates but have higher physical and psychosocial function. There were no associations made between silicone implants and cancer or systemic disease. There were no differences in outcomes or complications between round and shaped implants. Textured implants have a lower risk of capsular contracture than smooth implants. Smooth implants are more likely to be displaced as well as having higher rates of infection. Immediate breast reconstruction (IBR) gives the best aesthetic outcome if radiotherapy is not required but has a higher rate of capsular contracture and implant failure. Delayed-immediate reconstruction patients can achieve similar aesthetic results to IBR whilst preserving the breast skin if radiotherapy is required. Delayed breast reconstruction (DBR) patients have fewer complications than IBR patients. Conclusions Implant reconstruction is a safe and popular

The aim of this study was to quantify the variation in doses to organs at risk (ipsilateral lung and heart) and the clinical target volume (CTV) in the presence of breast implants. In this retrospective cohort study, patients were identified through the National Breast Cancer Register. Consecutive breast cancer patients undergoing mastectomy between 2009 and 2011 and completing a full course of postmastectomy radiotherapy (PMRT) were eligible. All included patients (n = 818) were identified in the ARIA© oncology information system and further stratified for immediate breast reconstruction (IBR+, n = 162) and no immediate breast reconstruction (IBR-, n = 656). Dose statistics for ipsilateral lung, heart and CTV were retrieved from the system. Radiation plans for patients with chest wall (CW) only (n = 242) and CW plus lymph nodes (n = 576) irradiation were studied separately. The outcome variables were dichotomized as follows: lung, V 20Gy ≤ 30% vs. V 20Gy > 30%; heart, D mean ≤ 5 Gy vs. D mean > 5 Gy; CTV, V 95% ≥ median vs. V 95% < median. In the univariate and multivariate regression models no correlation between potential confounders (i.e. breast reconstruction, side of PMRT, CW index) and the outcome variables was found. Multivariate analysis of CW plus lymph nodes radiation plans, for example, showed no association of breast reconstruction with dosimetric outcomes in neither lung nor heart- lung V 20Gy (odds ratio [OR]: 0.6, 95%CI, 0.4 to 1.0, p = 0.07) or heart D mean (OR: 1.2, 95%CI, 0.5 to 3.1, p = 0.72), respectively. CTV was statistically significantly larger in the IBR+ group (i.e. included breast implant), but no correlation between the implant type and dosimetric characteristics of the organs at risk was revealed. In the current study, the presence of breast implants during postmastectomy radiotherapy was not associated with increased doses to ipsilateral lung and heart, but CTV definition and its dosimetric characteristics urge further

To determine the effect of breast radiation (RT) on disease-free survival (DFS) and ipsilateral breast relapse (IBR) in women over 50 with T1 and T2 node negative breast cancer. Between December 1992 and June 2000, 769 women were randomized to RT and Tamoxifen (Tam) 20 mg daily for 5 years or Tam alone. Median age was 68 years, 639 patients had pT1 lesions and ER/PR were positive in 700 patients. Six hundred and thirty-four patients had pathologically negative nodes and 135 over age 65 were clinically node negative. Median follow-up was 5.6 years and patient and tumour characteristics were well balanced between the two arms. Overall, there were 54 relapses from breast cancer in the Tam arm and 27 in the Tam + RT arm. IBR at 5 years was 7.7% in the Tam arm compared to 0.6% in the Tam + RT group (p<0.0001). Significant factors for breast relapse and DFS at 5 years included tumour size (p=0.02 and 0.0001 respectively), hormone-receptor status (p=0.0008 and 0.0001), grade (p=0.001 and 0.003) and treatment arm (p=0.0001 and 0.004). Four-hundred and nineteen patients with low-risk features (T1, receptor-positive and grade 1/2) treated with Tam alone had a 5% risk of IBR at 5 years, increasing to 10% at 8 years. There was no difference in relapse at regional or distant sites, or in the contralateral breast. No difference was seen in the number of deaths due to breast cancer (13 and 11 for Tam + RT and Tam, respectively), nor in OS (93% at 5 years in both arms). Tamoxifen and breast RT results in a significantly lower rate of breast relapse than Tam alone in women over 50 with node-negative breast cancer. There does not appear to be a low-risk group who can be treated with Tamoxifen without breast radiation

Full Text Available The social dynamics in post-conflict Ambon, Maluku, 1999-2004, indicated that even though people were segregated in the ​​Islamic-Christian areas, gradually social integration began to occur naturally. The process of integration that occurred also gave birth to new values ​​and inclusive views that give hope to future peace building. Using the theory of social integration of dynamic adaptation of the Parsonian structural-functional classic paradigm and combined with a qualitative research model, this study successfully formulated several important findings. First, social integration occurred in the city of Ambon could run naturally through economic interactions, consensus on political balance and inclusive religious spirit. In addition, the presence of public spaces such as offices, schools, malls and coffee shops served as a natural integration medium that is increasingly important in the dynamics of the society. Second, the new social integration has created an increasingly important meaning that leads to a model of active harmony characterized by a process of the increasingly active social interaction between different religions, as well as strengthening pluralism and multiculturalism insight due to campaign by educational institutions and civil society groups. Third, this study also reminds us that although there has been a process of the increasingly positive social integration in Ambon city, people still need to be aware of the growth of radical religious ideologies at a certain level, and also of strengthening identity politics in the long run that will potentially give birth to primordial and ethnocentric attitudes that are harmful to the development of peace.

Feynman integrals and hyperlogarithms

Panzer, Erik

2015-02-05

We study Feynman integrals in the representation with Schwinger parameters and derive recursive integral formulas for massless 3- and 4-point functions. Properties of analytic (including dimensional) regularization are summarized and we prove that in the Euclidean region, each Feynman integral can be written as a linear combination of convergent Feynman integrals. This means that one can choose a basis of convergent master integrals and need not evaluate any divergent Feynman graph directly. Secondly we give a self-contained account of hyperlogarithms and explain in detail the algorithms needed for their application to the evaluation of multivariate integrals. We define a new method to track singularities of such integrals and present a computer program that implements the integration method. As our main result, we prove the existence of infinite families of massless 3- and 4-point graphs (including the ladder box graphs with arbitrary loop number and their minors) whose Feynman integrals can be expressed in terms of multiple polylogarithms, to all orders in the ε-expansion. These integrals can be computed effectively with the presented program. We include interesting examples of explicit results for Feynman integrals with up to 6 loops. In particular we present the first exactly computed counterterm in massless φ{sup 4} theory which is not a multiple zeta value, but a linear combination of multiple polylogarithms at primitive sixth roots of unity (and divided by the √(3)). To this end we derive a parity result on the reducibility of the real- and imaginary parts of such numbers into products and terms of lower depth.

Efforts to transform health care delivery to improve care have increasingly focused on care integration. However, variation in how integration is defined has complicated efforts to design, synthesize, and compare studies of integration in health care. Evaluations of integration initiatives would be enhanced by describing them according to clear definitions of integration and specifying which empirical relationships they seek to test-whether among types of integration or between integration and outcomes of care. Drawing on previous work, we present a comprehensive theoretical model of relationships between types of integration and propose how to measure them.

Collinear facilitation and contour integration in autism: evidence for atypical visual integration.

2015-01-01

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interaction, atypical communication and a restricted repertoire of interests and activities. Altered sensory and perceptual experiences are also common, and a notable perceptual difference between individuals with ASD and controls is their superior performance in visual tasks where it may be beneficial to ignore global context. This superiority may be the result of atypical integrative processing. To explore this claim we investigated visual integration in adults with ASD (diagnosed with Asperger's Syndrome) using two psychophysical tasks thought to rely on integrative processing-collinear facilitation and contour integration. We measured collinear facilitation at different flanker orientation offsets and contour integration for both open and closed contours. Our results indicate that compared to matched controls, ASD participants show (i) reduced collinear facilitation, despite equivalent performance without flankers; and (ii) less benefit from closed contours in contour integration. These results indicate weaker visuospatial integration in adults with ASD and suggest that further studies using these types of paradigms would provide knowledge on how contextual processing is altered in ASD.

Full Text Available The structural integration of separation processes, using multifunctional equipment, has been studied on four stage-wise liquid-liquid separations extraction, absorption, distillation, adsorption and on some combinations of these processes. It was shown for stage - wise processes that the ultimate aim of equipment integration is 3-way integration (by components by steps and by stages and that membrane multiphase contactors present concerning the equipment optimal solutions in many cases. First, by using partially integrated equipment and, later by developing fully integrated systems it was experimentally confirmed that structural 3-way integration produces much higher degrees of component separations and component enrichments in compact and safe equipment.

Full Text Available In our paper, the theory of bi-integrable and tri-integrable couplings is generalized to the discrete case. First, based on the six-dimensional real special orthogonal Lie algebra SO(4, we construct bi-integrable and tri-integrable couplings associated with SO(4 for a hierarchy from the enlarged matrix spectral problems and the enlarged zero curvature equations. Moreover, Hamiltonian structures of the obtained bi-integrable and tri-integrable couplings are constructed by the variational identities.

Searching for integrable systems

International Nuclear Information System (INIS)

Cary, J.R.

Lack of integrability leads to undesirable consequences in a number of physical systems. The lack of integrability of the magnetic field leads to enhanced particle transport in stellarators and tokamaks with tearing-mode turbulence. Limitations of the luminosity of colliding beams may be due to the onset of stochasticity. Enhanced radial transport in mirror machines caused by the lack of integrability and/or the presence of resonances may be a significant problem in future devices. To improve such systems one needs a systematic method for finding integrable systems. Of course, it is easy to find integrable systems if no restrictions are imposed; textbooks are full of such examples. The problem is to find integrable systems given a set of constraints. An example of this type of problem is that of finding integrable vacuum magnetic fields with rotational transform. The solution to this problem is relevant to the magnetic-confinement program

Strategic Integration: The Practical Politics of Integrated Research in Context

Directory of Open Access Journals (Sweden)

Lorrae van Kerkhoff

2005-01-01

Full Text Available Designing an integrative research program requires that research leaders negotiate a balance between the scientific interest of research and the practical interests of non-scientific partners. This paper examines the ways integrated research is formally categorised, and analyses the tangible expressions of the practical politics involved in reconciling scientific and practical interests. Drawing on a comparative study of two Australian Cooperative Research Centres, I argue that categories used by the research leaders to describe the research programs embody three different strategies for structuring the relationships between researchers and their partners. These include matching research program categories to partners’ implementation program categories, reproducing existing integrative partnership models, and filling gaps in understanding with new technical approaches. These strategies offer different advantages and disadvantages. The cases suggest that the integrative approach favoured by each Centre depended on issues such as the geographic scope of policy arenas, sources of scientific credibility, and the political risks facing partners. The practical politics of research organisation offers a new lens for understanding both the practice and theory of integrated research.

In 1992, the Secretary of Energy directed the Assistant Secretary for Environmental Management (EM) to develop an integrated, long-term, spent nuclear fuel (SNF) management program. In response, EM created the Integrated SNF Program to assess the US Department of Energy (DOE) SNF and SNF storage facilities. As shown in Figure 1 the Integrated SNF Program is responsible for life-cycle management of DOE SNF; that is characterization, processing, interim storage and preparation for disposal. In order to implement the Program it was recognized that technology needs must be identified. A Technology Integration Program was formed to integrate the DOE complex-wide efforts for establishing timely, cost effective and consistent technical criteria for the development of technical solutions. The program is directed toward identification of: (a) what activities need to be done, (b) when they need to be completed, and (c) what priority should be assigned to the various activities

Understanding integrated care: a comprehensive conceptual framework based on the integrative functions of primary care.

Primary care has a central role in integrating care within a health system. However, conceptual ambiguity regarding integrated care hampers a systematic understanding. This paper proposes a conceptual framework that combines the concepts of primary care and integrated care, in order to understand the complexity of integrated care. The search method involved a combination of electronic database searches, hand searches of reference lists (snowball method) and contacting researchers in the field. The process of synthesizing the literature was iterative, to relate the concepts of primary care and integrated care. First, we identified the general principles of primary care and integrated care. Second, we connected the dimensions of integrated care and the principles of primary care. Finally, to improve content validity we held several meetings with researchers in the field to develop and refine our conceptual framework. The conceptual framework combines the functions of primary care with the dimensions of integrated care. Person-focused and population-based care serve as guiding principles for achieving integration across the care continuum. Integration plays complementary roles on the micro (clinical integration), meso (professional and organisational integration) and macro (system integration) level. Functional and normative integration ensure connectivity between the levels. The presented conceptual framework is a first step to achieve a better understanding of the inter-relationships among the dimensions of integrated care from a primary care perspective.

Integration, de-integration and liberal controlled finance

2008-01-01

With the forthcoming adoption of the 3. directive of the European Commission project, the European Union will make a new step towards integration. The stake for gas or electric utilities is of prime importance: each will have to de-integrate and positioned itself as an infrastructure company or as a production and commercialization company. In other words, they will have to chose between 'regulation and recurrent incomes' or 'fortunes and risks of production and trade'. Such changes, added to the globalization of gas trades linked with the development of LNG, require more investments than in the past. However, these over-investments combined to technical progresses allow to expect that this mutation will not significantly weaken the security of gas supplies in the European Union. The end-user, on the other hand, will certainly not make any profit of this integration considering the enhanced volatility of markets more and more dominated by the speculative strategies of financial operators.

Energy integration: Regional economic integration lever and possible insertion factor in the global economy

International Nuclear Information System (INIS)

Lokolo, M.C.

2001-01-01

In the 1920s, just after the War, an idea began taking root in the Old Continent, to build what could be described as the United States of Europe. Thirty years later, in 1951, a new source of energy, coal, paved the way for the economic integration of Europe. It culminated into monetary integration in January 2002. Economic integration makes sense in the context of the relatively small size of some national economies and markets, and the judicious utilization of rare resources and their unequal distribution. In this document, the author elaborated on the principles at play in economic integration and argued that the integration of the national energy markets could be the lever for economic integration through the gradual elimination of the various obstacles to trade. The author first presented a brief historical overview of economic integration from the perspective of global economic relationships, covering the period between the two world wars to the General Agreement on Tariffs and Trade (GATT) to the World Trade Organization (WTO). The concept and the forms of economic integration were reviewed. Energy integration as a lever of regional economic integration and as a factor in global economic insertion were discussed.

TCR industrial system integration strategy

CERN Document Server

Bartolomé, R; Sollander, P; Martini, R; Vercoutter, B; Trebulle, M

1999-01-01

New turnkey data acquisition systems purchased from industry are being integrated into CERN's Technical Data Server. The short time available for system integration and the large amount of data per system require a standard and modular design. Four different integration layers have been defined in order to easily 'plug in' industrial systems. The first layer allows the integration of the equipment at the digital I/O port or fieldbus (Profibus-DP) level. A second layer permits the integration of PLCs (Siemens S5, S7 and Telemecanique); a third layer integrates equipment drivers. The fourth layer integrates turnkey mimic diagrams in the TCR operator console. The second and third layers use two new event-driven protocols based on TCP/IP. Using this structure, new systems are integrated in the data transmission chain, the layer at which they are integrated depending only on their integration capabilities.

Integrals over products of distributions and coordinate independence of zero-temperature path integrals

International Nuclear Information System (INIS)

Kleinert, H.; Chervyakov, A.

2003-01-01

In perturbative calculations of quantum-statistical zero-temperature path integrals in curvilinear coordinates one encounters Feynman diagrams involving multiple temporal integrals over products of distributions, which are mathematically undefined. In addition, there are terms proportional to powers of Dirac δ-functions at the origin coming from the measure of path integration. We give simple rules for integrating products of distributions in such a way that the results ensure coordinate independence of the path integrals. The rules are derived by using equations of motion and partial integration, while keeping track of certain minimal features originating in the unique definition of all singular integrals in 1-ε dimensions. Our rules yield the same results as the much more cumbersome calculations in 1-ε dimensions where the limit ε→0 is taken at the end. They also agree with the rules found in an independent treatment on a finite time interval

Feynman integral calculus

CERN Document Server

Smirnov, Vladimir A

2006-01-01

The problem of evaluating Feynman integrals over loop momenta has existed from the early days of perturbative quantum field theory. The goal of the book is to summarize those methods for evaluating Feynman integrals that have been developed over a span of more than fifty years. `Feynman Integral Calculus' characterizes the most powerful methods in a systematic way. It concentrates on the methods that have been employed recently for most sophisticated calculations and illustrates them with numerous examples, starting from very simple ones and progressing to nontrivial examples. It also shows how to choose adequate methods and combine them in a non-trivial way. This is a textbook version of the previous book (Evaluating Feynman integrals, STMP 211) of the author. Problems and solutions have been included, Appendix G has been added, more details have been presented, recent publications on evaluating Feynman integrals have been taken into account and the bibliography has been updated.

Abundo, Mario; Pirozzi, Enrica

2018-03-01

We find a representation of the integral of the stationary Ornstein-Uhlenbeck (ISOU) process in terms of Brownian motion Bt; moreover, we show that, under certain conditions on the functions f and g , the double integral process (DIP) D(t) = ∫βt g(s) (∫αs f(u) dBu) ds can be thought as the integral of a suitable Gauss-Markov process. Some theoretical and application details are given, among them we provide a simulation formula based on that representation by which sample paths, probability densities and first passage times of the ISOU process are obtained; the first-passage times of the DIP are also studied.

Organizational aspects of integrated reporting preparation according to international standard «Integrated reporting»

Directory of Open Access Journals (Sweden)

2016-12-01

Full Text Available Integrated Reporting is an innovative reporting for business entities, therefore the issue of the organization the preparation of this reporting is an actual. The absence of legislative regulation of integrated reporting at national level of legal documents has greatly affected the issue, because the only document, that specifies the requirements for integrated reporting is the international standard «integrated reporting». The article considers the organizational principles of integrated reporting preparation. Taking into account the requirements of the international standard «integrated reporting», the authors make the attempts to define the basic organizational stages of such reporting, that allows to introduce the integrated reporting in a structured way and logically. It is proposed on the enterprises preparing the integrated reporting to constitute the schedule of the formation of the integrated reporting. In addition, the important thing is to develop the internal policy for determining materiality by the use of the professional judgment. The appropriate internal policy is assigned to disclose the materiality process in an integrated reporting for decision-making on the inclusion or exclusion issues to be understandable for users.

1998-01-01

In Affine Toda field theory, links among three generating functions for integrals of motion derived from Part (I) are studied, and some classically integrable boundary conditions are obtained. An infinite number of integrals of motion are calculated in ZMS model with quasi-periodic condition. The authors find the classically integrable boundary conditions and K +- matrices of ZMS model with independent boundary conditions on each end. It is identified that an infinite number of integrals of motion does exist and one of them is the Hamiltonian, so this system is completely integrable

Toward a Comprehensive Framework for Evaluating the Core Integration Features of Enterprise Integration Middleware Technologies

Directory of Open Access Journals (Sweden)

Hossein Moradi

2013-01-01

Full Text Available To achieve greater automation of their business processes, organizations face the challenge of integrating disparate systems. In attempting to overcome this problem, organizations are turning to different kinds of enterprise integration. Implementing enterprise integration is a complex task involving both technological and business challenges and requires appropriate middleware technologies. Different enterprise integration solutions provide various functions and features which lead to the complexity of their evaluation process. To overcome this complexity, appropriate tools for evaluating the core integration features of enterprise integration solutions is required. This paper proposes a new comprehensive framework for evaluating the core integration features of both intra-enterprise and inter-enterprise Integration's enabling technologies, which simplify the process of evaluating the requirements met by enterprise integration middleware technologies.The proposed framework for evaluating the core integration features of enterprise integration middleware technologies was enhanced using the structural and conceptual aspects of previous frameworks. It offers a new schema for which various enterprise integration middleware technologies are categorized in different classifications and are evaluated based on their supporting level for the core integration features' criteria. These criteria include the functional and supporting features. The proposed framework, which is a revised version of our previous framework in this area, has developed the scope, structure and content of the mentioned framework.

The objectives of an integrated security system are to detect intruders and unauthorized activities with a high degree of reliability and the to deter and delay them until effective response/engagement can be accomplished. Definition of an effective integrated security system requires proper application of a system engineering methodology. This paper summarizes a methodology and describes its application to the problem of integrated security system definition. This process includes requirements identification and analysis, allocation of identified system requirements to the subsystem level and provides a basis for identification of synergistic subsystem elements and for synthesis into an integrated system. The paper discusses how this is accomplished, emphasizing at each step how system integration and subsystem synergism is considered. The paper concludes with the product of the process: implementation of an integrated security system

Full Text Available The paper examines systems integration and its main levels at higher levels of control. At present, the systems integration is one of the main aspects participating in the consolidation processes and financial flows of a company. Systems Integration is a complicated emotionconsuming process and it is often a problem to choose the right approach and level of integration. The research focused on four levels of integration, while each of them is characterized by specific conditions. At each level, there is a summary of recommendations and practical experience. The paper also discusses systems integration between the information and MES levels. The main part includes user-level integration where we describe an example of such integration. Finally, we list recommendations and also possible predictions of the systems integration as one of the important factors in the future.

An integral heuristic

International Nuclear Information System (INIS)

Kauffman, L.H.

1990-01-01

This paper gives a heuristic derivation of the skein relation for the Homfly polynomial in an integral formalism. The derivation is formally correct but highly simplified. In the light of Witten's proposal for invariants of links via functional integrals, it is useful to have a formal pattern to compare with the complexities of the full approach. The formalism is a heuristic. However, it is closely related to the actual structure of the Witten functional integral

Integrating data to acquire new knowledge: Three modes of integration in plant science.

Science.gov (United States)

Leonelli, Sabina

2013-12-01

This paper discusses what it means and what it takes to integrate data in order to acquire new knowledge about biological entities and processes. Maureen O'Malley and Orkun Soyer have pointed to the scientific work involved in data integration as important and distinct from the work required by other forms of integration, such as methodological and explanatory integration, which have been more successful in captivating the attention of philosophers of science. Here I explore what data integration involves in more detail and with a focus on the role of data-sharing tools, like online databases, in facilitating this process; and I point to the philosophical implications of focusing on data as a unit of analysis. I then analyse three cases of data integration in the field of plant science, each of which highlights a different mode of integration: (1) inter-level integration, which involves data documenting different features of the same species, aims to acquire an interdisciplinary understanding of organisms as complex wholes and is exemplified by research on Arabidopsis thaliana; (2) cross-species integration, which involves data acquired on different species, aims to understand plant biology in all its different manifestations and is exemplified by research on Miscanthus giganteus; and (3) translational integration, which involves data acquired from sources within as well as outside academia, aims at the provision of interventions to improve human health (e.g. by sustaining the environment in which humans thrive) and is exemplified by research on Phytophtora ramorum. Recognising the differences between these efforts sheds light on the dynamics and diverse outcomes of data dissemination and integrative research; and the relations between the social and institutional roles of science, the development of data-sharing infrastructures and the production of scientific knowledge.

Interface-based software integration

Directory of Open Access Journals (Sweden)

Aziz Ahmad Rais

2016-07-01

Full Text Available Enterprise architecture frameworks define the goals of enterprise architecture in order to make business processes and IT operations more effective, and to reduce the risk of future investments. These enterprise architecture frameworks offer different architecture development methods that help in building enterprise architecture. In practice, the larger organizations become, the larger their enterprise architecture and IT become. This leads to an increasingly complex system of enterprise architecture development and maintenance. Application software architecture is one type of architecture that, along with business architecture, data architecture and technology architecture, composes enterprise architecture. From the perspective of integration, enterprise architecture can be considered a system of interaction between multiple examples of application software. Therefore, effective software integration is a very important basis for the future success of the enterprise architecture in question. This article will provide interface-based integration practice in order to help simplify the process of building such a software integration system. The main goal of interface-based software integration is to solve problems that may arise with software integration requirements and developing software integration architecture.

What constitutes information integrity?

2008-01-01

Full Text Available This research focused on what constitutes information integrity as this is a problem facing companies today. Moreover, information integrity is a pillar of information security and is required in order to have a sound security management programme. However, it is acknowledged that 100% information integrity is not currently achievable due to various limitations and therefore the auditing concept of reasonable assurance is adopted. This is in line with the concept that 100% information security is not achievable and the notion that adequate security is the goal, using appropriate countermeasures. The main contribution of this article is to illustrate the importance of and provide a macro view of what constitutes information integrity. The findings are in harmony with Samuel Johnson's words (1751: 'Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.'

Integration of generic issues

International Nuclear Information System (INIS)

Thatcher, D.

1989-01-01

The NRC has recognized the need to integrate generic issues (GIs). The GI process includes a number of phases, all of which should recognize the potential for overlap and conflict among related issues. In addition to the issues themselves, other related NRC and industry programs and activities need to be factored into the GI process. Integration has taken place, or is taking place, for a number of GIs. Each case of integration involves a specific set of circumstances and, as a result, the way in which integration proceeds can vary. This paper discusses the integration of issues in the generic issue process and provides a number of examples

Commercially available phenyl-C-butyric acid methyl ester (PCBM) is crosslinked with 1,6-diazidohexane (DAZH), resulting in films resistant to common solvents used in perovskite solar cell processing. By using crosslinked PCBM as an interlayer and (HC(NH))(CHNH)PbIBr as the active layer, we achieve small area devices and modules with a maximum steady-state power conversion efficiency of 18.1% and 14.9%, respectively.

Abuse notation of improper integrals

Arfi, E.; Wiryanto, L. H.

2018-01-01

In the definition of \\int_ab {f(x)dx} , it was assumed that the interval [a, b] was finite. However, in many application in physics, engineering, economics, and probability we wish to allow a or b (or both) to be infinite or for the other case when f has an infinite discontinuity in [a, b]. In either case the integral is called improper integral. Definition of improper integral is the limit of a definite integral as an endpoint of the interval of integration approaches either a specified real number or ∞ or -∞ or, in some cases, as both endpoints approach limits. Many of the first-year students in ITERA learning about improper integrals make an abuse notation like written improper integral just like standard definite integral. Based on this situation, we tried to change the habits of the students in the writing of improper integrals by providing sufficient understanding and considerable exercises. It turns out this way gives good result, based on the percentage of the value of the midterms to the problem of improper integrals give a fairly good percentage value.
