Abstract: To investigate the association between periconceptional environmental exposures and the occurrence of cleft lips and palates.This case-control study analyzed 150 mothers of children with cleft lips and palates living in the same city as 250 mothers whose children did not present with this malformation (controls). Environmental exposure data were gathered through a questionnaire (Latin American Collaborative Study of Congenital Malformations methodology).Multivariate analysis revealed that monthly income below minimum wage, having another malformed child, other diseases in the first gestational trimester (urinary infection), use of pesticides in home gardens, and pesticide use in farms close to the home were risk factors associated with the malformation, whereas taking vitamins was a protective factor.Maternal and paternal exposure to pesticides is associated with cleft lip and palate in Mato Grosso State, Brazil.

2. Use of Recycled Construction and Demolition Waste (RCDW) in Geosynthetic-Reinforced Roadways: Influence of Saturation Condition on Geogrid Mechanical Properties

Author: Santos, Gabriel R. Silvestre, Mateus P. Fleury, Jefferson Lins da Silva, and Eder C. G.
Subjects: recycled waste materials, geosynthetics, laboratory and field testing, sustainable development
Abstract: Replacing natural aggregates in infrastructure with recycled construction and demolition waste (RCDW) works helps to meet the requirements established by sustainable development. This environmentally friendly proposal undoubtedly becomes better when it is carried out with geosynthetics, providing better technical performance and positive economic impacts. However, the chemical characteristics of RCDW may result in the degradation of the geosynthetics and, therefore, must be assessed and quantified. This study aims to assess the chemical degradation caused by RCDW for the mechanical properties of two types of polymeric geogrids (polyester and polyvinyl alcohol). The study evaluates the influence of the RCDW saturation condition in the chemical degradation and the possible synergism between the launching damage (drop height) and chemical degradation. Watertight tanks were constructed to maintain the geosynthetic reinforced layers in flooded, dry and open-to-environment conditions, simulating paved and unpaved roads. The occurrence of degradation was evaluated and quantified by reduction factors related to the properties of interest using statistical analysis. The results have shown a significant influence of chemical degradation on the geogrid characteristics (especially tensile strength and secant tensile stiffness), which increased when the specimens were subjected to prior launching process simulation. The reduction factor values reported herein encourage the combined use of these materials (geogrid and RCDW) and highlight the importance of assessing the chemical degradation for the design purposes of geosynthetic-reinforced roadways with alternative materials.

4. Plasma advanced glycation end products and soluble receptor for advanced glycation end products as indicators of sterol content in human carotid atherosclerotic plaques

Author: Raphael S Pinto, Guilherme S Ferreira, Gina Camillo R Silvestre, Monique de Fátima M Santana, Valéria S Nunes, Lucas Ledesma, Paula R Pinto, Sayonara Ivana S de Assis, Ubiratan F Machado, Erasmo S da Silva, and Marisa Passarelli

Abstract: Advanced glycation end products (AGEs) are independently related to cardiovascular disease (CVD) and favor cholesterol and oxysterol accumulation in macrophage foam cells. Soluble RAGE (sRAGE) impairs cellular AGE signaling alleviating the deleterious effects of AGE in atherogenesis. The association between plasma AGEs and sRAGE with the content of cholesterol, markers of cholesterol synthesis and absorption, and oxysterols in atherosclerotic plaques was evaluated in subjects undergoing carotid endarterectomy. Plasma and carotid plaques were obtained from symptomatic ( n = 23) and asymptomatic subjects ( n = 40). Lipids from plaques were extracted and sterols (oxysterols, cholesterol, desmosterol, lathosterol, sitosterol, and campesterol) were determined by using gas chromatography/mass spectrometry. Plasma total AGEs and pentosidine were measured by using fluorimetry and sRAGE by using ELISA. In symptomatic subjects´ atherosclerotic plaques, an increased amount of cholesterol (3x) and oxysterols [7 α-hydroxycholesterol (1.4x); 7 β−hydroxycholesterol (1.2x); 25-hydroxycholesterol (1.3x); 24-hydroxycholesterol (2.7x), and 27-hydroxycholesterol, (1.15x)], with exception to 7 ketocholesterol, were found in comparison to asymptomatic individuals. Plasma total AGEs and pentosidine significantly and positively correlated to sterols accumulated in the atherosclerotic lesion, including cholesterol, desmosterol, campesterol, sitosterol, and oxysterols. On the other hand, sRAGE inversely correlated to total AGEs and pentosidine in plasma, and with major species of oxysterols, cholesterol, and markers of cholesterol synthesis and absorption in the atherosclerotic lesion. In multiple regression analyses, it was observed a significant inverse correlation between sRAGE and 24-hydroxycholesterol and desmosterol, and a positive significant correlation between pentosidine and 24-hydroxycholesterol, 27-hydroxycholesterol, and campesterol. In conclusion, the plasma concentration of AGEs and sRAGE is a tool to predict the accumulation of sterols in atherosclerotic lesions in symptomatic and asymptomatic individuals, helping to prevent and improve the management of acute cardiovascular complications.

Abstract: This paper reports the development of a new propeller design and analysis tool. JBLADE uses an improved version of blade element momentum that embeds a new model for the three-dimensional flow equilibrium. In addition, a new method for the prediction of the airfoil drag coefficient at a 90 deg angle of attack for a better poststall modeling is also presented. The software is developed as an open-source tool for the simulation of propellers and has the capability to estimate the performance of a given propeller geometry in design and offdesign operating conditions. The software allows the introduction of the blade geometry as an arbitrary number of sections. To validate the code, the propellers from NACA Technical Report 530 by Gray (“Wind-Tunnel Tests of Two Hamilton Standard Propellers Embodying Clark Y and NACA 16-Series Blade Sections,” 1941) and NACA Technical Report 594 by Theodorsen et al. (“Characteristics of Six Propellers Including the High-Speed Range,” 1937) were simulated and the results were ...

Abstract: Two-particle angular correlations in jet cones have been measured in e(+)e(-) annihilation into hadrons at LEP energies (root s = 91 and 183 GeV) and are compared with QCD predictions using the LPHD hypothesis. Two different functions have been tested. While the differentially normalized correlation function shows substantial deviations from the predictions, a globally normalized correlation function agrees well. The size of alpha(s)(eff) land other QCD parameters) and its running with the relevant angular scale, the validity of LPHD, and problems due to non-perturbative effects are discussed critically.

Abstract: Although the legged robots are considered as the most versatile type due to their major capability of moving on uneven terrain, the studied robots have not yet much mobility. In general this lack of mobility is related to the high number of degrees of freedom that makes it difficult to solve their mathematical model and applying it to the control system. This problem impose them a low operational velocity. Also the mobile robots which legs are based on parallel structures have not yet solved this problem. One alternative is to use simpler mechanisms, having small number of dof, for the legs. The solution analyzed in this paper uses the Bennett’s linkage for a six legged robot. From the kinematic analysis of each leg, the robot motion is analyzed on two kinds of movement: the tripod type and the tetrapod type. In the present work the kinematic analysis of the robot behavior is analyzed in order to know, in advance, what can occur with the robot when it is walking. After the analysis some studies are proposed in such a way the robot can have a smooth movement, even considering its dynamics.

Abstract: The total and the differential cross sections for the reaction e+e− → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb−1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ− > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10−5, 5.5 × 10−5, 8.0 × 10−5, and 1.7 × 10−5 respectively. All the limits are at the 95% confidence level.

Abstract: A search for stable or long-lived heavy charged particles in e+e− interactions at energies of 130–136, 161 and 172 GeV has been performed using the data taken by the DELPHI experiment at LEP. The search is based on particle identification provided by the Time Projection Chamber and the Ring Imaging Cherenkov detector. Upper limits at 95% confidence level are derived on the cross-section for heavy long-lived pair-produced charge ±e and View the MathML source particles in the range of 0.4–2.3 pb for masses from 45 to 84 GeV/c2. Within supersymmetric extensions of the Standard Model, long-lived charginos with masses from 45 to 84 (80) GeV/c2 for high (low) sneutrino masses can be excluded at 95% confidence level. Left-handed (right-handed) long-lived or stable smuons and staus with masses between 45 and 68 (65) GeV/c2 can be excluded at 95% confidence level.

Abstract: We have searched for excited states of charged and neutral leptons, e∗, μ ∗ , τ ∗ and ν ∗ , in e+e− collisions at s =130 using the OPAL detector at LEP. No evidence for their existence was found. With the most common coupling assumptions, the final states from excited lepton pair production include l+l−γγ and l+l−WW (with the subsequent decay of the virtual W bosons). From the analysis of these final states, 95% confidence level lower mass limits of 66.5 GeV for e∗, 66.8 GeV for μ ∗ , 65.3 GeV for τ ∗ , 66.2 GeV for ν e ∗ , 66.5 GeV for ν μ ∗ and 64.7 GeV for ν τ ∗ are inferred. From the analysis of γγ final states with missing energy and using alternative coupling assignments which permit photonic ν ∗ decays, a 95% confidence level lower mass limit of 65.0 GeV for each ν ∗ flavour is inferred. From the analysis of the l+l−γ, acoplanar lepton pair, and single γ final states expected from excited lepton single production, upper limits on f Λ (ratio of the coupling to the compositeness scale) are determined for excited lepton masses up to the kinematic limit.

Abstract: Using data accumulated by DELPHI during the November 1995 LEP run at 130–136 GeV, searchs have been made for events with jets or leptons in conjunction with missing momentum. The results are interpreted in terms of limits on the production of neutralinos, scalar leptons, and scalar quarks.

19. Characterization of Leishmania infantum thiol-dependent reductase 1 and evaluation of its potential to induce immune protection

Abstract: The need to develop an effective vaccine against leishmaniasis to prevent the 2 million new cases each year led to the search for antigens able to elicit protection against infection with Leishmania. In this study, we have characterized a parasite-specific protein of Leishmania infantum named thiol-dependent reductase 1 (TDR1). The protein is present in both life cycle stages of L. infantum with a notable higher expression in the amastigote forms, suggesting a role in the interaction between the parasite and the mammalian host. Thiol-dependent reductase 1 is localized in the cytosol, although we were able to detect the protein in the culture medium of both promastigotes and axenic amastigotes, and consequently, TDR1 is considered an excreted/secreted molecule of the parasite. Therefore, we have evaluated the potential of TDR1 recombinant protein to protect against experimental challenge with L. infantum parasites using a murine model. Despite a reduction in spleen parasite load in the chronic phase of disease, TDR1 administration was not effective in the protection of Balb/c mice against visceral leishmaniasis and thus TDR1 do not have a crucial role in the modulation of mammalian host immune response, as observed with its protein counterpart Tc52 of Trypanosoma cruzi.

Abstract: © Springer-Verlag 2012, Amyotrophic Lateral Sclerosis (ALS) is a progressive and fatal neurodegenerative disease in which much burden is geared towards end-of-life care. Particularly in the earlier stages of ALS, many people have found both physiological and psychological boosts from various types of physical exercise for disused muscles. Proper exercise is important for preventing atrophy of muscles from disuse-a key for remaining mobile for as long as possible-and as long as it is possible to exercise comfortably and safely, for preserving cardiovascular fitness. However, the typical neuromuscular patient features a great physical inactivity and disuse weakness, and for that reason many controversial authors have contested exercise in these patients during years, especially in ALS which is rapidly progressive. There is an urgent need for dissecting in detail the real risks or benefits of exercise in controlled clinical trials to demystify this ancient paradigm. Yet, recent research studies document significant benefits in terms of survival and quality of life in ALS, poor cooperation, small sample size, uncontrolled and short-duration trials, remain the main handicaps. Sedentary barriers such as early fatigue and inherent muscle misuse should be overcome, for instance with body-weight supporting systems or non-invasive ventilation, and exercise should be faced as a potential non-monotonous way for contributing to better health-related quality of life.

Abstract: During intracellular parasitic infections, pathogens and host cells take part in a complex web of events that are crucial for the outcome of the infection. Modulation of host cell apoptosis by pathogens attracted the attention of scientists during the last decade. Apoptosis is an efficient mechanism used by the host to control infection and limit pathogen multiplication and dissemination. In order to ensure completion of their complex life cycles and to guarantee transmission between different hosts, intracellular parasites have developed mechanisms to block apoptosis and sustain the viability of their host cells. Here, we review how some of the most prominent intracellular protozoan parasites modulate the main mammalian apoptotic pathways by emphasizing the advances from the last decade, which have begun to dissect this dynamic and complex interaction.

22. The Leishmania nicotinamidase is essential for NAD+ production and parasite proliferation

Abstract: NAD+ is a central cofactor that plays important roles in cellular metabolism and energy production in all living cells. Genomics-based reconstruction of NAD+ metabolism revealed that Leishmania protozoan parasites are NAD+ auxotrophs. Consequently, these parasites require assimilating NAD+ precursors (nicotinamide, nicotinic acid, nicotinamide riboside) from their host environment to synthesize NAD+ by a salvage pathway. Nicotinamidase is a key enzyme of this salvage pathway that catalyses conversion of nicotinamide (NAm) to nicotinic acid (Na), and that is absent in higher eukaryotes. We present here the biochemical and functional characterizations of the Leishmania infantum nicotinamidase (LiPNC1). Generation of Lipnc1 null mutants leads to a decrease in NAD+ content, associated with a metabolic shutdown-like phenotype with an extensive lag phase of growth. Both phenotypes could be rescued by an add-back construct or by addition of exogenous Na. In addition, Lipnc1 null mutants were unable to establish a sustained infection in a murine experimental model. Altogether, these results illustrate that NAD+ homeostasis is a fundamental component of Leishmania biology and virulence, and that NAm constitutes its main NAD+ source in the mammalian host. The crystal structure of LiPNC1 we solved allows now the design of rational inhibitors against this new promising therapeutic target.

Abstract: This paper describes a software platform oriented to the augmented reality/mixed reality application developer, aiming at simplifying his/her programming tasks. This platform comprises a software development kit (SDK) for the Windows environment, consisting of a set of C++ classes packaged into modules. The platform is known as MX toolkit and utilises extensively the AR toolkit, for all matters regarding marker-based tracking, but is defined at a somewhat higher abstraction level than the AR toolkit software layer, by hiding from the programmer, low level implementation details and facilitating AR/MR object-oriented programming. The MX toolkit is presented by means of a comparison with the AR toolkit processing pipeline and API and by explaining its eight system modules. We expect to provide this package as an aid for AR toolkit-based applications development. The paper also describes a visual AR/MR authoring tool, the Mix It application, from the user interface point of view, as an illustration of the development support potential of the MX toolkit SDK.

Abstract: This work reports and experiments a tangible mixed reality system for architectural design usage scenarios, such as conceptual design, client brief or architectural design education. The system provides the means for an architect to intuitively interact with an augmented version of a real scale model, in normal working settings, where he can observe 3D virtual objects registered to the real ones. Intuitive tangible interfaces, implemented with paddles, are used to aid design and editing tasks in the mixed environment. By means of paddle gesturing recognition, it is possible to activate a menu, browse and choose menu options or pick, move, rotate and scale 3D virtual objects, within the scale model working area. To transport the user from augmented reality to a fully virtual environment (supporting real-time scene navigation, while in VR mode) and back, paddle gesturing recognition is also used. Complex architectural designs, described in the VRML 97 data format, can be imported into our system, which provides a platform, for testing now design concepts while seamlessly transporting the architect in a truly mixed reality environment: from reality (RE) to augmented reality (AR) and then through augmented virtuality (AV), towards a full virtual environment (VE), and back.

Abstract: The events with two photons and missing (transverse) energy collected by the DELPHI detector at centre-of-mass energies between 130~GeV and 183~GeV have been studied to search for processes of the type $\mbox{e}^+\mbox{e}^- \to \mbox{Y} \mbox{Y}$ with the subsequent decay $\mbox{Y} \to \mbox{X} \gamma$, where X is an undetectable neutral particle. Reactions of this kind are expected in supersymmetric models, where the Y particle can be either the lightest neutralino, decaying to a photon and a gravitino, or the next-to-lightest neutralino, decaying to a photon and the lightest neutralino. To study the case of long-lived Y particles, a search for single-photon events with the reconstructed photon axis pointing far from the beam interaction region has also been performed. No evidence for a deviation from Standard Model expectations has been observed in the data and upper limits have been derived on the signal cross-section as a function of the the X and Y masses and of the Y mean decay path.

Author: C. Moscardó, C. Esquembre, E. Blanco, M. Tasso, and R. Silvestre
Subjects: Pediatrics, Perinatology and Child Health, Pediatrics, RJ1-570
Abstract: Introduccion La quimioterapia (QT) es una alternativa en el manejo de los gliomas de bajo grado (GBG) pediatricos no resecables, permitiendo retrasar el uso de radioterapia (RT) en ninos de corta edad. No existe consenso en cuanto a drogas y esquemas terapeuticos. La vinblastina (VBL) a dosis de 6 mg/m 2 semanal se ha utilizado en ninos con GBG que desarrollaron reacciones de hipersensibilidad al carboplatino, con distintos grados de respuesta y sin toxicidad significativa. Estudios preclinicos han demostrado que, administrada a dosis bajas, posee actividad antiangiogenica. Esta caracteristica podria resultar util en el tratamiento de los GBG, tal y como apuntan algunos estudios descritos en la literatura. Objetivo Analizar la eficacia y toxicidad del tratamiento con VBL en ninos con GBG. Matrial y metodos Estudio retrospectivo de 4 ninos con GBG tratados con VBL a dosis de 6 mg/m 2 semanal en nuestra Unidad entre 2003 y 2006. En dos casos se administro como tratamiento de segunda linea por ser refractarios y en otros dos como tratamiento inicial. Resultados Se describen en la tabla 3: Conclusiones La utilizacion de VBL en pacientes con GBG es particularmente atractiva por tratarse de un farmaco eficaz con excelente tolerancia incluso durante periodos prolongados de tiempo. Estas caracteristicas permiten cumplir objetivos como retrasar la RT en casos seleccionados o mantener estable la enfermedad en casos refractarios, con buena calidad de vida. Es necesario desarrollar estudios clinicos mas amplios para definir el papel de dicha droga en el tratamiento de este tipo de tumores pediatricos.

Subjects: Pediatrics, Perinatology and Child Health, Pediatrics, RJ1-570
Abstract: Introduccion Las terapias que habitualmente se han utilizado en la histiocitosis son efectivas, pero las frecuentes recidivas y resistencias plantean dilemas terapeuticos. En los ultimos anos se esta investigando sobre el uso de la 2-clorodesoxiadenosina (2-CdA) en estos pacientes. Se trata de un analogo de las purinas con un doble efecto, antiproliferativo e inmunomodulador. No hay acuerdo en la dosificacion y forma de administracion. Se describen ciclos de 3 a 13 mg/m 2 /dia durante 3 o 5 dias, en perfusion de entre 2-24 h, con intervalos de 21-28 dias y un maximo de 6 ciclos. Objetivo Analizar la eficacia, seguridad y forma de administracion de la 2-CdA en ninos con histiocitosis recurrente o refractaria. Material y metodos Estudio retrospectivo de 6 ninos, cinco con histiocitosis de celulas de Langerhans (2 recurrentes y 3 refractarias) y uno con enfermedad de Rosai-Dorfman refractaria, tratados con 2-CdA en nuestra unidad entre 1999 y 2005. Se describen los siguientes datos de todos los pacientes: edad, sexo, organos afectados y tratamientos previos; dosis, forma de administracion, respuesta y toxicidad con la 2-CdA. Resultados Los pacientes fueron en su mayoria varones (5:1), con una edad mediana de 2,3 anos (9 meses-8,5 anos). Todos presentaban enfermedad multisistemica, uno de ellos con afectacion de organos de riesgo. La 2-CdA fue tratamiento de segunda linea en cuatro de los casos y de tercera linea en dos. En 4 ninos se administraron dosis bajas (5-6,5 mg/m 2 /dia × 3 dias, 6 ciclos), en uno intermedias (7 mg/m 2 /dia × 5 dias, 2 ciclos) y altas (14 mg/m 2 /dia × 3 dias, 4 ciclos) en una paciente por falta de respuesta a dosis bajas. De los 31 ciclos administrados, 18 fueron mediante infusion continua y 13 en infusion de 3 h. La paciente tratada con altas dosis obtuvo muy buena respuesta parcial pero presento toxicidad hematologica de grado IV con afectacion de las 3 series, lo que obligo a suspender el tratamiento. El cuadro se resolvio progresivamente en 6 meses sin haber presentado complicaciones graves durante el periodo de aplasia. A dosis bajas e intermedias no se observaron toxicidades significativas. Tras una mediana de seguimiento de 3,5 anos, 4 pacientes se hallan en remision completa (3,5-8,6 anos), uno en muy buena respuesta parcial (9 meses) y uno fallecio por progresion de la enfermedad. Discusion En nuestra experiencia la 2-CdA se ha mostrado eficaz en histiocitosis recurrentes/refractarias. La toxicidad es sobre todo hematologica y directamente relacionada con la dosis. A dosis bajas e intermedias es muy bien tolerada, mientras que a dosis altas pueden llegar a producir aplasia medular prolongada en el tiempo, aunque no se han descrito hasta el momento complicaciones graves. Tal y como aparece en la literatura especializada, la infusion en 3 h frente a la continua parece igual de eficaz sin aumentar la toxicidad, y posibilita su administracion de forma ambulatoria. El perfil de eficacia y tolerancia de la 2-CdA permite su utilizacion precoz en histiocitosis de evolucion torpida. Se necesitan mas estudios para determinar la dosis, formas de administracion e indicaciones optimas para cada paciente.

Abstract: This paper presents results on charged Higgs boson production, based on LEP data collected at √s = 172 GeV, that complement the previous DELPHI results obtained at centre of mass energies up to 161 GeV. The charged Higgs bosons are assumed to be pair produced and to decay either into a quark pair or into τVτ. The three different possible final states are included in the analysis. Data from ring imaging Cherenkov and microvertex detectors are used to identify the quarks as a cs pair. The number of candidates found is compatible with the background expected from standard processes. Combining the results of the present analysis with those of the previous analysis at lower energies, a new lower mass limit for the charged Higgs boson is set at 54.5 GeV/c2. © 1998 Elsevier Science B.V.

Abstract: The value of the b quark mass at the M Z scale defined in the MS renormalization scheme, m b ( M Z ), was determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be m b (M Z )=2.67±0.25 ( stat. )±0.34 ( frag. )±0.27 ( theo. ) GeV/c 2 . The analysis considers NLO corrections to the three-jet production rate including mass effects, and the result obtained agrees with the QCD prediction of having a running b quark mass at an energy scale equal to M Z . This is the first time that such a measurement is performed far above the b b production threshold. The study also verifies the flavour independence of the strong coupling constant for b and light quarks within 1% accuracy.

Abstract: The data collected by DELPHI in 1996 have been used to measure the average charged particle multiplicities and dispersions in $q\bar{q}$ events at centre-of-mass energies of $\sqrt{s}=161$~GeV and $\sqrt{s}=172$~GeV, and the average charge multiplicity in WW events at $\sqrt{s}=172$~GeV. The multiplicities in $q\bar{q}$ events are consistent with the evolution predicted by QCD. The dispersions in the multiplicity distributions are consistent with Koba-Nielsen-Olesen (KNO) scaling. The average multiplicity of charged particles in hadronic W decays has been measured for the first time; its value, $19.23 \pm 0.74 (stat+syst)$, is consistent with that expected for an $e^+e^-$ interaction at a centre-of-mass energy equal to the W mass. The charged particle multiplicity in W decays shows no evidence of effects of colour reconnection between partons from different W's at the present level of statistics.

Abstract: Trilinear gauge boson couplings are measured using data taken by DELPHI at 161 GeV and 172 GeV, Values for WWV couplings (V = Z,gamma) are determined from a study of the reactions e(+)e(-) --> W+W- and e(+)e(-) --> We nu, using differential distributions from the WW final state in which one W decays hadronically and the other leptonically, and total cross,section data from other channels, Limits are also derived on neutral ZV gamma couplings from an analysis of the reaction e(+)e(-) --> gamma + invisible particles.

Abstract: In an analysis of multihadronic events recorded at LEP by DELPHI in the years 1992 through 1994, charged hadrons are identified using the measurement of their energy loss and their Cherenkov angle. Rapidity correlations of \La-\La, proton-proton, and \La-proton pairs are compared. The agreement with the string and cluster fragmentation models is tested. For those pairs that frame a meson in terms of rapidity the compensation of strangeness is studied. For \La{}$\overline{\mathrm{p}}$ pairs the additional correlation with respect to charged kaons is analysed.

Abstract: The spin density matrix elements for the rho(0), K-*0(892) and phi produced in hadronic Z(0) decays are measured in the DELPHI detector. There is no evidence for spin alignment of the K-*0(892) and phi, in the region x(p) less than or equal to 0.3 (x(p) = p/p(beam)), where rho(00) = 0.33 +/- 0.05 and rho(00) = 0.30 +/- 0.04, respectively. In the fragmentation region, x(p) greater than or equal to 0.4, there is some indication for spin alignment of the rho(0) and K-*0(892), since rho(00) = 0.43 +/- 0.05 and rho(00) = 0.46 +/- 0.08, respectively. These values are compared with those found in meson-induced hadronic reactions. For the phi, rho(00) = 0.30 +/- 0.04 for x(p) greater than or equal to 0.4 and 0.55 +/- 0.10 for x(p) greater than or equal to 0.7. The off-diagonal spin density matrix element rho(1-1) is consistent with zero in all cases. (C) 1997 Published by Elsevier Science B.V.

Abstract: An inclusive measurement of the average multiplicity of b (b) over bar pairs from gluons, g(b (b) over bar), in hadronic Z(0) events collected by the DELPHI experiment at LEP, is presented. A counting technique, based on jet b-tagging in 4-jet events, has been used. Looking for secondary bottom production in events with production of any primary flavour, by requiring two b-tagged jets in well defined topological configurations, gave g(b (b) over bar) = (0.21 +/- 0.11(stat) +/- 0.09(syst))%. This result was checked with a different method designed to select events with four b quarks in the final state. Agreement within the errors was found. (C) 1997 Elsevier Science B.V.

Abstract: In a sample of 3.02 million hadronic $Z^o$ decays collected by the DELPHI detector, 270 $J/\psi \into$ \lplm candidates have been selected. A search for fully reconstructed $B_c\upm$ mesons has yielded one $B_c\upm\to J/\psi ~\pi\upm$ candidate, no $B_c\upm \into J/\psi ~\ell\upm ~\nu_\ell$ candidates, and one $B_c\upm \into J/\psi ~\pi^+~\pi^- ~\pi\upm$ candidate, consistent with expected background in each channel. The following 90\% confidence level upper limits are determined: r(Z^o \into B_c\upm ~X) \times Br(B_c\upm \into J/\psi ~\pi\upm) (1.05~{\mathrm{to}}~0.84) \times 10^{-4} and r(Z^o \into B_c\upm ~X) \times Br(B_c\upm \into J/\psi ~\ell\upm ~\nu_\ell) (5.8~{\mathrm{to}}~5.0) \times 10^{-5}, where the ranges quoted correspond to the range of predicted $B_c\upm$ lifetimes from 0.4 to 1.4 ps, and r(Z^o \into B_c\upm ~X) \times Br(B_c\upm \into J/\psi ~\pi^+ ~\pi^- ~\pi\upm) 1.75 \times 10^{-4}, constant over the range of predicted $B_c\upm$ lifeti

Abstract: An upper limit for BR(Z(0) --> 3g) is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sample of threefold symmetric three-jet events collected by the DELPHI experiment at LEP during 1991-1994, the 95% confidence level upper limit is deduced to be: BR(Z(0) --> 3g) less than or equal to 1.6 x 10(-2) for the JADE and BR(Z(0) --> 3g) less than or equal to 1.5 x 10(-2) for the DURHAM jet-finder.

38. First Report of Potato yellowing virus (Genus Ilarvirus) in Solanum phureja from Ecuador

Abstract: A bacilliform virus, named Potato yellowing virus (PYV), causing chlorosis of leaves was reported in 1992 in potato (Solanum tuberosum) fields in Peru (1) and symptomless wild potatoes (S. fernandezianum) in Chile (4). PYV is reported as an alfamo-like virus (1) (family Bromoviridae) but no sequence information is available for this virus, making its taxonomic position inside the Bromoviridae uncertain (currently this family is organized into five genera: Alfamovirus, Bromovirus, Cucumovirus, Ilarvirus, and Oleavirus). Herein we report the presence of PYV in native potatoes (Solanum phureja) collected from Ecuador where the crop constitutes an important source of income in rural communities. Forty accessions of S. phureja collected in Ecuador in June 1986 and maintained in vitro at the International Potato Center (CIP) germplasm bank were analyzed by double-antibody sandwich (DAS)-ELISA with antiserum raised against a Peruvian isolate of PYV (1). PYV was detected in six accessions (15% of the material) corresponding to cultivars Chaucha Tomate and Chaucha Blanca (from the province of Cañar), Chaucha Negra Ojona and Chaucha Amarilla (Loja Province), and Cuica and Chaucha (Azuay Province). Mechanical inoculation of the indicator plant Physalis floridiana with leaf extracts of these six plants, a PYV isolate from Peru (1) (positive control), and an additional four plants testing negative for PYV (negative controls) induced symptoms of mosaic and leaf deformation only with the six clones from Ecuador and the PYV isolate from Peru. To further confirm the presence of the virus, we used universal PCR primers designed for the Bromoviridae (Ilar1F5: 5′-GCNGGWTGYGGDAARWCNAC-3′ and Ilar1R7: 5′-AMDGGWAYYTGYTYNGTRTCACC-3′) that target the helicase motif (RNA1) (3). Total RNA was extracted from 200 mg of leaf material (from potato and mechanically inoculated P. floridiana) using Trizol (Invitrogen, Carlsbad, CA) following the manufacturer's instructions and cDNA was synthesized using random hexamer primers. We obtained a reverse transcription-PCR amplified band only from samples that were DAS-ELISA positive to PYV. To identify the virus at the genus level, we cloned the PCR fragments (265 nucleotides) from four of the samples from Ecuador and the Peruvian isolate into plasmid vectors (pGEM-T Easy Vector cloning system; Promega, Madison, WI) for Sanger sequencing (Macrogen, Seoul, Korea). Phylogenetic analysis grouped PYV sequences with those of the genus Ilarvirus. Among the ilarviruses, Fragaria chiloensis latent virus (2) was the closest relative of PYV, with which it shares 77% nucleotide and 85% amino acid sequence identity. PYV isolates from Ecuador split into two different variants (91% identity) that shared 93% nucleotide and 99% amino acid sequence identity with the Peruvian isolate. Collectively, the data suggest that PYV is a distinct ilarvirus and that it is more widely spread among South American potatoes than previously suggested. The GenBank Accession Numbers for the sequences described are: HQ141053 (Loja1), HQ141054 (Azuay), HQ141055 (Cañar), and HQ141056 (Loja2) for the isolates from Ecuador and HQ141057 (PYV-Cañete) for the isolate from Peru.

Abstract: In 1996 LEP ran at a centre-of-mass energy of 161~GeV, just above the threshold of W-pair production. DELPHI accumulated data corresponding to an integrated luminosity of $9.93 {\mathrm{~pb^{-1}}}$, and observed 29 events that are considered as candidates for W-pair production. From these, a cross-section for the doubly resonant $e^+e^-\to\mathrm{WW}$ process of $3.67~^{+0.97}_{-0.85} \pm 0.19{\mathrm{~pb}}$ has been measured. Within the Standard Model, this cross-section corresponds to a mass of the W-boson of ${\mathrm{80.40~\pm~0.44~(stat.)~\pm~0.09~(syst.) ~\pm 0.03~(LEP)~GeV}}/c^2$. Alternatively, if $m_{\mathrm{W}}$ is held fixed at its current value determined by other experiments, the observed cross-section is used to obtain limits on trilinear ${\mathrm{WWV (V \equiv \gamma, Z)}}$ couplings.

Abstract: The hadronic fragmentation functions of the various quark flavours and of gluons are measured in a study of the inclusive hadron production from $\zz$ decays with the DELPHI detector and are compared with the fragmentation functions measured elsewhere at energies between 14 GeV and 91 GeV. A large scaling violation is observed, which is used to extract the strong coupling constant from a fit using a numerical integration of the second order DGLAP evolution equations. The result is \begin{displaymath} \alpha_s(M_Z) = 0.124^{+0.006}_{-0.007}(exp)\pm 0.009 (theory) \end{displaymath} where the first error represents the experimental uncertainty and the second error is due to the factorization and renormalization scale dependence.

Abstract: Event shape and charged particle inclusive distributions are measured using 750000 decays of the $Z$ to hadrons from the DELPHI detector at LEP. These precise data allow a decisive confrontation with models of the hadronization process. Improved tunings of the JETSET ARIADNE and HERWIG parton shower models and the JETSET matrix element model are obtained by fitting the models to these DELPHI data as well as to identified particle distributions from all LEP experiments. The description of the data distributions by the models is critically reviewed with special importance attributed to identified particles.

Abstract: Using D*+ mesons exclusively reconstructed in the DELPHI detector at LEP, an excess of 66 +/- 14(stat.) events is observed in the D(*+)pi(+)pi(-) final state with a mass of 2637 +/- 2(stat.) +/- 6(syst.) MeV/c(2) and a full width smaller than 15 MeV/c(2) (95% C.L.). This signal is compatible with the expected decay of a radially excited D*' (J(P) = 1(-))meson.

Abstract: A sample of about 1.4 million hadronic Z decays, selected among the data recorded by the DELPHI detector at LEP during 1994, was used to measure for the first time the momentum spectra of K+, K-0, p, Lambda and their antiparticles in gluon and quark jets. As observed for inclusive charged particles, the production spectra of identified particles were found to be softer in gluon jets than in quark jets, with a higher total multiplicity.

Abstract: Data taken by DELPHI during the 1995 and 1996 LEP runs have been used to search for the supersymmetric partners of electron, muon and tau leptons and of top and bottom quarks. The observations are in agreement with standard model predictions. Limits are set on sfermion masses. Searches for long lived scalar leptons from low scale supersymmetry breaking models exclude stau masses below 55~GeV/c$^2$ at the 95\% confidence level, irrespective of the gravitino mass.

Abstract: The hadronic structure of the decay of the $\tau$ lepton to three charged particles, $\tau\rightarrow 3\pi\nu_\tau$, is studied using data collected by the DELPHI detector at LEP between 1992 and 1995. The invariant mass of the $3\pi$ system, $m_{3\pi}$, is fitted using the models of KIhn and Santamaria, Isgur Morningstar and Reader, and Feindt. The $3\pi$ mass spectrum and the Dalitz projections are compared with each model. Below \mbox{$m_{3\pi}^2 = 2.3~ {\GeV}^2$}, all are in good qualitative agreement. Above \mbox{$m_{3\pi}^2 = 2.3~ {\GeV}^2$}, anomalous behaviour is observed, consistent with the existence of a hitherto unseen decay mode of the $\tau$ through a radial excitation of the $a_1$ meson.

Abstract: Correlations between pions from different W's in e(+)e(-) --> W+W- events are studied using data collected by the DELPHI detector at LEP running at a centre-of-mass energy of 172 GeV in 1996. At the present level of statistics, no enhancement of the correlation function above that expected from a pair of uncorrelated W's is observed at small values of the four-momentum difference of the pions.

Abstract: Weak isosinglet Neutral Heavy Leptons ($\nu_m$) have been searched for using data collected by the DELPHI detector corresponding to $3.3\times 10^{6}$ hadronic~Z$^{0}$ decays at LEP1. Four separate searches have been performed, for short-lived $\nu_m$ production giving monojet or acollinear jet topologies, and for long-lived $\nu_m$ giving detectable secondary vertices or calorimeter clusters. No indication of the existence of these particles has been found, leading to an upper limit for the branching ratio $BR($Z$^0\rightarrow \nu_m \overline{\nu})$ of about $1.3\times10^{-6}$ at 95\% confidence level for $\nu_m$ masses between 3.5 and 50 GeV/$c^2$. Outside this range the limit weakens rapidly with the $\nu_m$ mass. %Special emphasis has been given to the search for monojet--like topologies. One event %has passed the selection, in agreement with the expectation from the reaction: %$e^+e^- \rightarrow\ell \bar\ell \nu\bar\nu$. The results are also interpreted in terms of limits for the single production of excited neutrinos.

Abstract: The DELPHI experiment at LEP has measured the inclusive charmless B hadron decay branching ratio, the B branching ratio into two charmed particles, and the total number of charmed particles per B decay, using the hadronic Z data taken between 1992 and 1995. The results are extracted from a fit to the b-tagging probability distribution based on the precise impact parameter measurements made using the microvertex detector. The inclusive charmless B branching ratio, including B decays into hidden charm (c (c) over bar), is measured to be 0.033 +/- 0.021. The B branching ratio into two open charmed particles is 0.136 +/- 0.042. The mean number of charmed particles per B decay (including hidden charm) is 1.147 +/- 0.041. After subtracting the B decay branching ratio into hidden charm, the charmless B branching ratio is found to be 0.007 +/- 0.021, compatible with the Standard Model expectation. Models that predict an additional contribution to the charmless B branching ratio of 0.037 or higher are excluded with at least 95% confidence. (C) 1998 Elsevier Science B.V. All rights reserved.
