    The NASA New Millennium Program (NMP) is a testbed for new, high-risk technologies, including new software and hardware. The Autonomous Sciencecraft Experiment (ASE) will fly on the Air Force Research Laboratory TechSat-21 mission in 2006 is such a NMP mission, and is managed by the Jet Propulsion Laboratory, California Institute of Technology. TechSat-21 consists of three satellites, each equipped with X-band Synthetic Aperture Radar (SAR) that will occupy a 13-day repeat track Earth orbit. The main science objectives of ASE are to demonstrate that process-related change detection and feature identification can be conducted autonomously during space flight, leading to autonomous onboard retargeting of the spacecraft. This mission will observe transient geological and environmental processes using SAR. Examples of geologic processes that may be observed and investigated include active volcanism, the movement of sand dunes and transient features in desert environments, water flooding, and the formation and break-up of lake ice. Science software onboard the spacecraft will allow autonomous processing and formation of SAR images and extraction of scientific information. The subsequent analyses, performed on images formed onboard from the SAR data, will include feature identification using scalable feature "templates" for each target, change detection through comparison of current and archived images, and science discovery, a search for other features of interest in each image. This approach results in obtaining the same science return for a reduced amount of resource use (such as downlink) when compared to that from a mission operating without ASE technology. Redundant data is discarded. The science-driven goals of ASE will evolve during the ASE mission through onboard replanning software that can re-task satellite operations. If necessary, as a result of a discovery made autonomously by onboard science processing, existing observation sequences will be pre-empted to

    OBJECTIVES. Dissatisfaction with services has been associated with poorer child mental health outcomes, early treatment termination as well as disagreements over the nature of mental health difficulties, reasons for referral and therapy goals. The development of straightforward, reliable, and accurate methods of eliciting service users' views is essential within child and adolescent mental health care. This paper describes the development of the child and adolescent service experience (ChASE), a tool to measure children and young people's service experience DESIGN. The study comprises a non-experimental, cross-sectional design. METHODS. Participants were 132 mental health service users aged 8-18 years. Participants and their main carer completed the ChASE, Parent Satisfaction Questionnaire (PSQ) (Stallard, 1996) and Strengths and Difficulties (SDQ) Impact Supplement. Clinicians completed the SDQ Impact Supplement and provided clinical activity data. A sub-sample of participants completed the ChASE on a second occasion, 6 weeks after the completion of the first questionnaire. RESULTS. Scrutiny of ChASE data indicated high levels of completion. Principal axis factoring identified three factors within the ChASE: Relationship, Privacy, and Session Activity. The ChASE has good internal consistency and test-retest reliability. Significant correlations were found between the ChASE and carer satisfaction, service use, and youth clinical outcomes. CONCLUSIONS. The ChASE is a short, psychometrically robust tool for routine measurement of children, and young people's experience of mental health services, which users can complete easily. The results underline the importance of alliance factors to children and young people and their association with clinical improvement as well as the potential for the ChASE to be used a measure of children's therapeutic progress and alliance. ©2011 The British Psychological Society.

    Recent results are presented in the study of radioisotope electric propulsion as a near-term technology for sending small robotic sciencecraft to the outer Solar System and near-interstellar space. Radioisotope electric propulsion (REP) systems are low-thrust, ion propulsion units based on radioisotope electric generators and ion thrusters. Powerplant specific masses are expected to be in the range of 100 to 200 kg/kW of thrust power. Planetary rendezvous missions to Pluto, fast missions to the heliopause (100 AU) with the capability to decelerate an orbiter for an extended science program and prestellar missions to the first gravitational lens focus of the Sun (550 AU) are investigated

    Full Text Available A psoríase é uma doença da pele relativamente freqüente, que afeta de 1% a 3% da população geral e atinge homens e mulheres, e é mais freqüente na raça branca. Caracteriza-se pelo aparecimento na pele de lesões róseas ou avermelhadas, recobertas de escamas secas e esbranquiçadas. Muitas vezes, essas lesões estão localizadas apenas nos cotovelos, joelhos ou couro cabeludo. Em outros casos, as lesões podem se espalhar por toda a pele, atingir unhas e, raramente, as articulações, causando a artrite psoriásica. A psoríase pode ser dividida em classes: vulgar, pustulosa, artrite psiriásica e psoríase eritrodérmica.

  7. Gamma-radiation effect of the ATP-ASE-activity in various parts of cotton sprouts

    1975-01-01

    ATP-ase is a thiol enzyme whose sulfhydryl group plays an important role. The transport of substances through biological membranes is the result of the action of the sodium-potassium pump of the cell, which functions with ATP energy. The action of this transport mechanism depends on the activity of ATP-ase. It may be postulated, therefore, that the suppression of the active transport of Na + and K + ions in cells under irradiation is partially the result of a disturbance of the activity of the ATP enzyme system. The author studied the effect of gamma radiation on ATP-ase activity in various parts of seven-day-old seedlings of type 108-F cotton, which were irradiated using Co 60 gamma radiation. The results of the experiment showed that the ATP-ase activity of the cotton seedling rootlets depends on the dose and the time elapsed after irradiation (a table is given). Small radiation doses (0.2 and 0.5 krad) significantly increased ATP-ase activity in the rootlets, while heavy doses inhibited it significantly. Similar results were obtained for the stems and leaves (tables are given). It was estblished that the ATP-ase of cotton seedlings has varying sensitivity to irradiation. The most sensitive ATP-ases were those of the rootlets. The activity of background ATP-ase is less subject to change than Na + and K + activated ATP-ases. For example, while the activity of ATP-ase (without ions) was inhibited by 25% when a 25 krad irradiation dose was administered, the retardation of Na + and K + activated ATP-ases reached 41%. The author suggests that the inhibition of ATP-ase activity under irradiation is mainly the result of a disturbance of the structure of the membrane functions. It is also possible that ATP-ase activity decreases because of a lack of the enzyme substrate - ATP, which is formed during the process of oxydative phosphorylization. A table is also provided showing the effect of irradiation on the activity of ATP-ase activated by various ions in the roots of

    Full Text Available Infection of humans with embryonated eggs of Toxocara canis (larva migrans remains asymptomatic, or results in covert or common toxocarosis, visceral larva migrans syndrome, or ophthalmologic and neurologic impairment. Though neurological manifestations of Toxocara canis larvae are rare, toxocarosis remains an important differential diagnosis of various neurological disorders. Manifestations of the central nervous system are dementia, meningo-encephalitis, myelitis, cerebral vasculitis, epilepsy, or optic neuritis. Manifestations of the peripheral nervous system comprise radiculitis, affection of cranial nerves, or musculo-skeletal involvement. If toxocarosis is neglected, ignored, or refused as a differential of these abnormalities, it may be easily overlooked for years. Early recognition and treatment of the infection is, however, of paramount importance since it reduces morbidity and mortality and the risk of secondary superinfection. Like the visceral manifestations, neurological manifestations of toxocarosis are treated by benzimidazole components, most frequently albendazole, corticosteroids, or diethylcarbamazine. If detected and treated early, the prognosis of neurological manifestations of toxocarosis is favourable.Infecção humana com ovos embrionados de Toxocara canis (larva migrans pode permanecer assintomática ou resultar em toxocaríase acentuada ou comum, síndrome da larva migrans visceral ou manifestações neurológicas ou oftalmológicas. Embora manifestações neurológicas das larvas de Toxocara canis sejam raras, a toxocaríase permanece como importante diagnóstico diferencial de várias manifestações neurológicas. Manifestações do sistema nervoso central são demência, meningoencefalite, mielite, vasculite cerebral, epilepsia, ou neurite ótica. Manifestações do sistema nervoso periférico compreendem radiculite, agressão de nervos cranianos ou envolvimento músculo-esquelético. Se a toxocaríase

    Full Text Available As mulheres portadoras de hanseníase, durante grande parte do século XX, não puderam exercer a maternidade devido à política de isolamento compulsório dos doentes adotada para controlar a doença. Os filhos ao nascerem eram levados para os preventórios e o contato com estes era realizado pelo olhar. Visando compreender a experiência da maternidade no hospital colônia foi realizada pesquisa narrativa com três mães que viveram o período de internação compulsória. Os discursos revelam dois momentos distintos da vivência de maternidade: a separação dos filhos com sua posterior volta para casa e a adoção de crianças para realizar a maternidade. Considera-se que a adoção promoveu o encontro com o sentido da existência que havia sido rompido e possibilitou a experiência de ser-mãe.In the twentieth century, women with leprosy could not carry on their maternity because of the statement of compulsory isolation of patients, adopted to control the disease. Their children were taken at birth to prevention centers and the contact of mothers with their babies was only visual. In order to understand the experience of maternity in the leprosaria it was carried out an investigated narrative research with three mothers who lived through the period of compulsory internment. The speeches reveal two distinct moments in the experience of motherhood: the separation of the children with their subsequent return to home and the adoption of other children to achieve motherhood. It is considered that the adoption has promoted the meeting with the meaning of existence that had been broken and allowed the experience of being a parent.

    1986-01-01

    Detection of pancreas necrosis was attempted in dog experiments. Strong association between pancreatic DNA-ase and actin molecules in vitro provided the theoretical basis for the procedure. Pancreatic DNA-ase labelled with 125 I was administered intravenously to dogs in which experimental pancreas necrosis was elicited. Accumulation ratio of radioactivity was above 20 in the necrotic pancreas whereas it varied between 1.6 and 5.6 in other tissues. After administration of 37 MBq 131 I labelled DNA-ase, accumulation of radioactivity could be clearly visualized in the necrotic portions of the removed pancreas by a gamma camera. The investigations will be extended in order to develop a clinically utilizable test. (L.E.)

    1997-01-01

    The possible reasons why an oil or gas company would seek public equity and financing and a listing on a stock exchange were discussed. This crucial decision for junior companies is often prompted by the need for expansion capital. In the last three years, 456 companies decided to list on the Alberta Stock Exchange (ASE) using the two most commonly used methods of going public: the Exchange Offering Prospectus (EOP) program, and the Junior Capital Pool (JCP) program. The EOP program is a simplified form of prospectus in which the distribution of securities is made through the facilities of the ASE. Companies that do not have significant operating assets, other than cash, nor agreements in place to acquire operating assets, are eligible under the JCP program which involves a two-stage process. Stage one requires the filing and clearing of a prospectus through the Alberta Securities Commission and the listing of the company's shares on the Exchange. Stage two requires completing a major transaction within 18 months of being listed on the Exchange. Details of the minimum listing requirements for either the EOP or the JCP programs were described

    1978-01-01

    The influence of the post-radiation factor helping the restoration of radiation damages in the early sorts of cotton plant 1306'DV Goss. hirsutum was studied. In particular the action of treating the irradiated seed in the solution of calcium salts on the functional state of alcaline and acid forms of nucleases in cellular components was investigated. The dry seed of cotton was irradiated with gamma-rays at dose of 30 krad. It was found that irradiation of the dry seed at the radiosensitive organ (roots) increased the acid DNA-ase in the cellular nuclei, in the radioresistant (leaves) - the alcaline DNA-ase and RNA-ase. With irradiation both forms of DNA-ase in the mitochondriae diminished. After treatment of the irradiated seed in the solution of calcium salts the activity of acid nucleases and alcaline enzymes remained normal

    This report presents the essential features and highlights of the 1998 Summer Faculty Fellowship Program at Ames Research Center and Dryden Flight Research Center in a comprehensive and concise form. Summary reports describing the fellows' technical accomplishments are enclosed in the attached technical report. The proposal for the 1999 NASA-ASEE-Stanford Summer Faculty Fellowship Program is being submitted under separate cover. Of the 31 participating fellows, 27 were at Ames and 4 were at Dryden. The Program's central feature is the active participation by each fellow in one of the key technical activities currently under way at either the NASA Ames Research Center or the NASA Dryden Flight Research Center. The research topic is carefully chosen in advance to satisfy the criteria of: (1) importance to NASA, (2) high technical level, and (3) a good match to the interests, ability, and experience of the fellow, with the implied possibility of NASA-supported follow-on work at the fellow's home institution. Other features of the Summer Faculty Fellowship Program include participation by the fellows in workshops and seminars at Stanford, the Ames Research Center, and other off-site locations. These enrichment programs take place either directly or remotely, via the Stanford Center for Professional Development, and also involve specific interactions between fellows and Stanford faculty on technical and other academic subjects. A few, brief remarks are in order to summarize the fellows' opinions of the summer program. It is noteworthy that 90% of the fellows gave the NASA-Ames/Dryden- Stanford program an "excellent" rating and the remaining 10%, "good." Also, 100% would recommend the program to their colleagues as an effective means of furthering their professional development as teachers and researchers. Last, but not least, 87% of the fellows stated that a continuing research relationship with their NASA colleagues' organization probably would be maintained. Therefore

    Full Text Available A psoríase, doença inflamatória crônica é caracterizada por lesões dérmicas sobrepostas a áreas de lesões eritematosas ou pustulares. Ocorre pela alteração no ciclo de crescimento das células epidérmicas, levando ao espessamento epidérmico decorrente da hiperproliferação celular e vascular com presença de infiltrado linfocitário. Pode desencadear manifestações como febre, mal-estar, fraqueza e outros. Seu diagnóstico é predominantemente clínico, podendo ser complementado pela biópsia das lesões. Entretanto, alguns casos encontrados na literatura e no caso que será relatado existe a presença de eosinofilia, mesmo na ausência de fatores que justificariam o surgimento desse sinal em pacientes portadores da psoríase. Objetivo: Relatar o caso de paciente encaminhado à hematologia com quadro de psoríase concomitante à eosinofilia. Relato de Caso: Paciente de 67 anos, masculino, vem encaminhado com hipótese diagnóstica de Síndrome Hipereosinofílica. Queixa de eosinofilia persistente (>1500 por mais de seis meses tendo realizado tratamento com Albendazol e Metronidazol, sem êxito. Concomitantemente, apresenta psoríase em acompanhamento da dermatologia sem sintomas sistêmicos. Exames laboratoriais: NR para Hepatite B ou C, HIV ou Toxocara canis. Ausência de população celular com imunofenótipo anômalo. Aumento do percentual de granulócitos eosinófilos. Coleta de JAK2 e BLC/ABR negativos. Tratamento da psoríase é realizado com shampoo indicado. Após dois meses, ainda apresenta eosinófilos = 1820. Conclusão: Recentemente, estabeleceu-se uma relação entre a eosinofilia e o aparecimento da psoríase. Não encontramos mais nenhuma causa possível que explique a eosinofilia deste paciente. Pretendemos acompanhá-lo e avaliar se o tratamento da psoríase relaciona-se com a diminuição da eosinofilia

    Full Text Available Reflective semiconductor optical amplifier fiber cavity lasers (RSOA-FCLs are appealing, colorless, self-seeded, self-tuning and cost-efficient upstream transmitters. They are of interest for wavelength division multiplexed passive optical networks (WDM-PONs based links. In this paper, we compare RSOA-FCLs with alternative colorless sources, namely the amplified spontaneous emission (ASE spectrum-sliced and the externally seeded RSOAs. We compare the differences in output power, signal-to-noise ratio (SNR, relative intensity noise (RIN, frequency response and transmission characteristics of these three sources. It is shown that an RSOA-FCL offers a higher output power over an ASE spectrum-sliced source with SNR, RIN and frequency response characteristics halfway between an ASE spectrum-sliced and a more expensive externally seeded RSOA. The results show that the RSOA-FCL is a cost-efficient WDM-PON upstream source, borrowing simplicity and cost-efficiency from ASE spectrum slicing with characteristics that are, in many instances, good enough to perform short-haul transmission. To substantiate our statement and to quantitatively compare the potential of the three schemes, we perform data transmission experiments at 5 and 10 Gbit/s.

    1999-10-19

    To safeguard the environmental friendliness of photovoltaics, the PV industry follows a proactive, long-term environmental strategy involving a life-of-cycle approach to prevent environmental damage by its processes and products from cradle to grave. Part of this strategy is to examine substituting lead-based solder on PV modules with other solder alloys. Lead is a toxic metal that, if ingested, can damage the brain, nervous system, liver and kidneys. Lead from solder in electronic products has been found to leach out from municipal waste landfills and municipal incinerator ash was found to be high in lead also because of disposed consumer electronics and batteries. Consequently, there is a movement in Europe and Japan to ban lead altogether from use in electronic products and to restrict the movement across geographical boundaries of waste containing lead. Photovoltaic modules may contain small amounts of regulated materials, which vary from one technology to another. Environmental regulations impact the cost and complexity of dealing with end-of-life PV modules. If they were classified as hazardous according to Federal or State criteria, then special requirements for material handling, disposal, record-keeping and reporting would escalate the cost of decommissioning the modules. Fthenakis showed that several of today's x-Si modules failed the US-EPA Toxicity Characteristic Leaching Procedure (TCLP) for potential leaching of Pb in landfills and also California's standard on Total Threshold Limit Concentration (TTLC) for Pb. Consequently, such modules may be classified as hazardous waste. He highlighted potential legislation in Europe and Japan which could ban or restrict the use of lead and the efforts of the printed-circuit industries in developing Pb-free solder technologies in response to such expected legislation. Japanese firms already have introduced electronic products with Pb-free solder, and one PV manufacturer in the US, ASE Americas has used a

Although the influence of many factors that are assumed to be fixed (ceteris paribus are very strong-such as macroeconomic variables GDP, economic growth and inflation, they left various conclusions and debates. FDI can be one of the important sources of capital in developing countries, and contribute, the national development by transfer of asset, management, and technology to stimulate the economy of the country. The research model uses some domestic characteristics, that will be combined in a short and long run period by using OLS. The Error Correction Model (ECM and Granger Causality Test, are applied to the determine the factors that influence the foreign direct investment (FDI in Indonesia within 1978 -2001. The result shows that economic variables such as GDP, growth, wage and export have positive effect to FDI. While non-economic variables such as Political Stability (SP shows a negative effect.

    The Autonomous Sciencecraft Experiment (ASE), part of the New Millennium Space Technology 6 Project, is flying onboard the Earth Orbiter 1 (EO-1) mission. The ASE software enables EO-1 to autonomously detect and respond to science events such as: volcanic activity, flooding, and water freeze/thaw. ASE uses classification algorithms to analyze imagery onboard to detect chang-e and science events. Detection of these events is then used to trigger follow-up imagery. Onboard mission planning software then develops a response plan that accounts for target visibility and operations constraints. This plan is then executed using a task execution system that can deal with run-time anomalies. In this paper we describe the autonomy flight software and how it enables a new paradigm of autonomous science and mission operations. We will also describe the current experiment status and future plans.

    2014-09-01

    Differential scanning calorimetry was used to study the crystallization behaviour of selenium thin films in dependence on film thickness and deposition rate. In the current work, which is the fourth in a sequence of articles dealing with crystallization kinetics of a-Se, the non-isothermal crystallization kinetics was described in terms of the Johnson-Mehl-Avrami nucleation-growth model. Two-dimensional crystallite growth, consistent with the idea of sterically restricted crystallization in a thin layer, was confirmed for all data. It was found that neither the film thickness (tested within the 100-2350 nm range) nor the deposition rate appears to have any significant influence on the crystallization kinetics. However, the higher amount of intrinsic defects possibly produced by a higher deposition rate seems to accelerate the crystallization, shifting it towards lower temperatures. Very good correlation between the results obtained for thin films and those for fine powders was found. Based on the obtained results, interpretations of relevant literature data were made.

    2016-04-18

    We study the field-of-view (FOV) of an upconversion imaging system that employs an Amplified Spontaneous Emission (ASE) fiber source to illuminate a transmission target. As an intermediate case between narrowband laser and thermal illumination, an ASE fiber source allows for higher spectral intensity than thermal illumination and still keeps a broad wavelength spectrum to take advantage of an increased non-collinear phase-matching angle acceptance that enlarges the FOV of the upconversion system when compared to using narrowband laser illumination. A model is presented to predict the angular acceptance of the upconverter in terms of focusing and ASE spectral width and allocation. The model is experimentally checked in case of 1550-630 nm upconversion.

Another objective of the study is to evaluate the sensitivity of consumer price indices to exchange rates for each country as well as to test for differences between atual exchange rates and their PPP predicted rates. The results show that in the long-run, actual exchange rates continually move toward the purchasing power predicted rates. On the other hand, in the short-run, the actual and parity exchange rates often experience disequilibrium. It was also found that positive changes in society's purchasing power caused positive changes in the actual exchange rates in every country except Japan.

    2016-11-01

    Full Text Available Background: Anomalous self-experiences (ASEs aggregate in schizophrenia spectrum disorders, but the relationship between ASEs, and depression has been studied to a limited extent. Lower self-esteem has been shown to be associated with depression in early psychosis. Our hypothesis is that ASEs in early phases of schizophrenia are linked to lower levels of self-esteem, which in turn is associated with depression. Aim: The aim is to examine the relationship between ASEs, self-esteem and depression in first-episode schizophrenia spectrum disorders.Method: ASEs were assessed in 55 patients with first-episode schizophrenia by means of the Examination of anomalous Self-Experience (EASE instrument. Assessment of depression was based on the Calgary Depression Scale for Schizophrenia (CDSS. Self-esteem was measured using the Rosenberg Self-Esteem Scale (RSES. Symptom severity was assessed using the Structured Clinical Interview for the Positive and Negative Syndrome Scale (SCI-PANSS. Substance misuse was measured with the Drug Use Disorder Identification Test (DUDIT, and alcohol use was measured with the Alcohol Use Disorder Identification Test (AUDIT. Data on childhood adjustment were collected using the Premorbid Adjustment Scale (PAS. Data on childhood trauma were collected using the Norwegian version of the Childhood Trauma Questionnaire, short form (CTQ-SF. Results: Analyses detected a significant association between current depression and ASEs as measured by the EASE in women, but not in men. The effect of ASEs on depression appeared to be mediated by self-esteem. No other characteristics associated with depression influenced the relationship between depression, self-esteem and ASEs. Conclusion: Evaluating ASEs can assist clinicians in understanding patients’ experience of self-esteem and depressive symptoms. The complex interaction between ASEs, self-esteem, depression and suicidality could be a clinical target for the prevention of suicidality

    The quantum yield for light-induced H2 generation was measured for a previously optimized bio-hybrid cytochrome c 6-crosslinked PSI(C13G)-1,8-octanedithiol-[FeFe]-H2ase(C97G) (PSI-H2ase) nanoconstruct. The theoretical quantum yield for the PSI-H2ase nanoconstruct is 0.50 molecules of H2 per photon absorbed, which equates to a requirement of two photons per H2 generated. Illumination of the PSI-H2ase nanoconstruct with visible light between 400 and 700 nm resulted in an average quantum yield of 0.10-0.15 molecules of H2 per photon absorbed, which equates to a requirement of 6.7-10 photons per H2 generated. A possible reason for the difference between the theoretical and experimental quantum yield is the occurrence of non-productive PSI(C13G)-1,8-octanedithiol-PSIC13G (PSI-PSI) conjugates, which would absorb light without generating H2. Assuming the thiol-Fe coupling is equally efficient at producing PSI-PSI conjugates as well as in producing PSI-H2ase nanoconstructs, the theoretical quantum yield would decrease to 0.167 molecules of H2 per photon absorbed, which equates to 6 photons per H2 generated. This value is close to the range of measured values in the current study. A strategy that purifies the PSI-H2ase nanoconstructs from the unproductive PSI-PSI conjugates or that incorporates different chemistries on the PSI and [FeFe]-H2ase enzyme sites could potentially allow the PSI-H2ase nanoconstruct to approach the expected theoretical quantum yield for light-induced H2 generation.

    Background: Anomalous self-experiences (ASEs) aggregate in schizophrenia spectrum disorders, but the relationship between ASEs, and depression has been studied to a limited extent. Lower self-esteem has been shown to be associated with depression in early psychosis. Our hypothesis is that ASEs in early phases of schizophrenia are linked to lower levels of self-esteem, which in turn is associated with depression. Aim: The aim is to examine the relationship between ASEs, self-esteem and depression in first-episode schizophrenia spectrum disorders. Method: ASEs were assessed in 55 patients with first-episode schizophrenia by means of the Examination of anomalous Self-Experience (EASE) instrument. Assessment of depression was based on the Calgary Depression Scale for Schizophrenia (CDSS). Self-esteem was measured using the Rosenberg Self-Esteem Scale (RSES). Symptom severity was assessed using the Structured Clinical Interview for the Positive and Negative Syndrome Scale (SCI-PANSS). Substance misuse was measured with the Drug Use Disorder Identification Test (DUDIT), and alcohol use was measured with the Alcohol Use Disorder Identification Test (AUDIT). Data on childhood adjustment were collected using the Premorbid Adjustment Scale (PAS). Data on childhood trauma were collected using the Norwegian version of the Childhood Trauma Questionnaire, short form (CTQ-SF). Results: Analyses detected a significant association between current depression and ASEs as measured by the EASE in women, but not in men. The effect of ASEs on depression appeared to be mediated by self-esteem. No other characteristics associated with depression influenced the relationship between depression, self-esteem and ASEs. Conclusion: Evaluating ASEs can assist clinicians in understanding patients' experience of self-esteem and depressive symptoms. The complex interaction between ASEs, self-esteem, depression and suicidality could be a clinical target for the prevention of suicidality in this

    All-optical regenerators can be used to suppress amplified spontaneous emission (ASE) noise introduced by cascaded erbium doped fiber amplifiers (EDFAs) in optical fiber communication systems and lead to the improvement of optical receiver sensitivity. By introducing the Q-factor transfer function (QTF), we evaluate the Q-factor performance of degenerate four-wave mixing (DFWM) regenerators with clock pump and reveal the differences between the optimal input powers determined from the static and dynamic power tranfer function (PTF) and the QTF curves. Our simulation shows that the clock-pump regnerator is capable of improving the Q-facor and receiver sensitivity for 40 Gbit/s ASE-degraded return-to-zero on-off keying (RZ-OOK) signal by 2.58 dB and 4.2 dB, respectively.

    Amorphous selenium (a-Se) and a-Se_9_5Sb_5 alloy were prepared using melt quenching technique. X-ray diffraction (XRD) pattern confirmed the amorphous nature of the prepared samples. Composition of the prepared samples has been determined using Energy dispersive X-ray fluorescence (EDXRF) technique. Differential thermal analysis (DTA) confirmed the glassy nature of the prepared samples. Thin films of the prepared samples were deposited on glass substrate using thermal evaporation method. Amorphous nature of the deposited films was confirmed using XRD. Optical properties of these films were obtained from the UV-VIS transmission spectra, at normal incidence, over 200-1100 nm spectral range. The optical absorption edge was described by using the model given by the Tauc. Optical band gap of the deposited films was calculated using Tauc plot. Optical characterization showed that average transmission and optical band gap decreased with the addition of antinomy.

  8. Pulse distortion, energy extraction, and ASE in an HF amplifier with angular multiplexing

    International Nuclear Information System (INIS)

    McGuire, E.J.

    1976-09-01

    It has been proposed that 1 ns pulses can be efficiently extracted from the e-beam initiated HF laser by angular multiplexing, i.e., filling the amplifier with the 1 ns pulses, 1 ns apart in time, each pulse at a slightly different angle; each pulse has an input intensity of 1 W/cm 2 per line and almost fills the amplifier. We have treated this in a one dimensional model, neglecting transverse amplified spontaneous emission. We conclude that the scheme is efficient, and that most of the pulses are amplified but not distorted. The first few pulses are distorted by transient effects and the last pulse has an enhanced tail. The ratio of peak pulse intensity to forward ASE at the output is 10 4 . We then include transverse ASE and find a drastically different situation. ASE saturates the inversion after a short time depending on pulse intensity (4 ns at I/sub o/ = 1 W/cm 2 , 7 ns at I/sub o/ = 100 W/cm 2 ). The saturation time is only weakly dependent on the transverse reflection coefficient. Calculations were done on an amplifier system designed for 10 KJ output. At an incident peak pulse intensity of 10 4 W/cm 2 -line (.77 MW/cm 2 for 77 lines) 2.5 KJ was obtained in amplified pulse energy, i.e., only 6 pulses of the 24 pulse train were fully amplified. The calculations indicate that double passing the pulse train through the amplifier would enhance the energy extracted

    Hoefler, F.

    2002-01-01

    Full text: Accelerated solvent extraction (ASE) is a modern extraction technique that significantly streamlines sample preparation. A common organic solvent as well as water is used as extraction solvent at elevated temperature and pressure to increase extraction speed and efficiency. The entire extraction process is fully automated and performed within 15 minutes with a solvent consumption of 18 ml for a 10 g sample. For many matrices and for a variety of solutes, ASE has proven to be equivalent or superior to sonication, Soxhlet, and reflux extraction techniques while requiring less time, solvent and labor. First ASE has been applied for the extraction of environmental hazards from solid matrices. Within a very short time ASE was approved by the U.S. EPA for the extraction of BNAs, PAHs, PCBs, pesticides, herbicides, TPH, and dioxins from solid samples in method 3545. Especially for the extraction of dioxins the extraction time with ASE is reduced to 20 minutes in comparison to 18 h using Soxhlet. In food analysis ASE is used for the extraction of pesticide and mycotoxin residues from fruits and vegetables, the fat determination and extraction of vitamins. Time consuming and solvent intensive methods for the extraction of additives from polymers as well as for the extraction of marker compounds from herbal supplements can be performed with higher efficiencies using ASE. For the analysis of chemical weapons the extraction process and sample clean-up including derivatization can be automated and combined with GC-MS using an online ASE-APEC-GC system. (author)

Apresentou evolução satisfatória, estando assintomática dois meses após a intervenção. A miíase vulvar deve ser considerada no diagnóstico diferencial das doenças infecciosas vulvares de doentes com hábitos de higiene precários.Myiasis located in the vulva is a rarely described disease. The objective of the present report is to describe a case of vulvar myiasis due to larvae of Cochliomyia hominivorax. A 77-year-old woman with precarious hygienic habits presented pain, pruritus and secretions with a fetid smell in the genital region for 10 days. Gynecological examination demonstrated an ulcerated lesion in the labium majus of the vulva measuring six centimeters that extended to the mons pubis and was found to be filled with larvae. The patient progressed favorably after removal of the larvae, surgical debridement and daily dressings. Fourteen days after the debridement, she was submitted to skin flap rotation, with good local scar formation. Two months after the intervention, she remained asymptomatic. Vulvar myiasis must be considered in the differential diagnosis of infectious diseases of the vulva in patients with precarious hygienic habits.

    Full Text Available Este trabalho foi desenvolvido para estudar os fatores que influem no adoecimento dos contatos intradomiciliares de hanseníase. Foi estabelecida uma coorte de contatos intradomiciliares de hanseníase no setor de Hanseníase da Fiocruz, no Rio de Janeiro. Entre 1987 e 1991, em que foram acompanhados 670 contatos saudáveis, a taxa de incidência por pessoa-ano de follow-up foi de 0,01694. Porém, houve variação com o tempo de acompanhamento de cada indivíduo, sendo de 0,06385 ao final do primeiro ano, de 0,03299 ao final do segundo, 0,02370 ao final do terceiro, 0,018622 ao final do quarto e 0,01694 ao final do período. Foi especificado um modelo de regressão logística para os indivíduos acompanhados nos primeiros cinco anos, envolvendo 758 contatos, incluindo nessa situação os casos co-prevalentes. O risco de incidência de hanseníase está relacionado com a negatividade do teste de Mitsuda, com OR de 3,093 (IC95% = 1,735-5,514, com a vacinação pelo BCG, OR de 0,3802 (IC95% = 0,2151-0,66719, e com a forma multibacilar do caso-índice, OR de 2,547 (IC95% = 1,249-5,192. Os resultados indicam que a incidência da hanseníase em contatos está associada à forma multibacilar da doença e aos fatores imunes dos contatos.

    The methods of accelerated solvent extraction (ASE) and supercritical fluid extraction (SFE) of polycyclic aromatic hydrocarbons (PAHs), aliphatic hydrocarbons, and chlorinated hydrocarbons from marine samples were investigated. The results of extractions of a certified sediment and four samples of suspended particulate matter (SPM) were compared to classical Soxhlet (SOX), ultrasonication (USE), and methanolic saponification extraction (MSE) methods. The recovery data, including precision and systematic deviations of each method, were evaluated statistically. It was found that recoveries and precision of ASE and SFE compared well with the other methods investigated. Using SFE, the average recoveries of PAHs in three different samples ranged from 96 to 105%, for ASE the recoveries were in the range of 97-108% compared to the reference methods. Compared to the certified values of sediment HS-6, the average recoveries of SFE and ASE were 87 and 88%, most compounds being within the limits of confidence. Also, for alkanes the average recoveries by SFE and ASE were equal to the results obtained by SOX, USE, and MSE. In the case of SFE, the recoveries were in the range 93-115%, and ASE achieved recoveries of 94-107% as compared to the other methods. For ASE and SFE, the influence of water on the extraction efficiency was examined. While the natural water content of the SPM sample (56 wt %) led to insufficient recoveries in ASE and SFE, quantitative extractions were achieved in SFE after addition of anhydrous sodium sulfate to the sample. Finally, ASE was applied to SPM-loaded filter candles whereby a mixture of n-hexane/acetone as extraction solvent allowed the simultaneous determination of PAHs, alkanes, and chlorinated hydrocarbons.

    Full Text Available Durante o curso da hanseníase, o edema comumente descrito como um sintoma de estados reacionais, pode ocorrer. Tanto o diagnóstico como a terapêutica adequada são, freqüentemente, difíceis de conseguir e assim podem acarretar permanente dano aos membros inferiores. Em um ano de acompanhamento, pacientes hansenianos - 10 multibacilares e 1 paucibacilar -, que foram submetidos a um protocolo clínico para o diagnóstico e classificação histopatológica, apresentaram clinicamente edema, localizado ou sistêmico. Entre estes pacientes, cinco apresentaram simultaneamente outros sintomas de reação, 4 foram classificados como reação Tipo I e um como reação tipo II. Por outro lado, três pacientes não apresentaram reação no momento do diagnóstico, mas desenvolveram alguns aspectos de reação posteriormente (2 tiveram neurite e um teve reação tipo I. Os edemas observados precedendo ou associados a quadros reacionais apresentaram ótima resposta clínica às drogas de ação anti-inflamatória (corticóide, talidomida e pentoxifilina utilizadas para o tratamento dos estados reacionais, na ausência de qualquer outro tratamento normalmente usado para edema. Embora necessitem ser confirmados por estudos controlados, estes dados sugerem fortemente que mecanismos imunológicos estejam envolvidos na fisiopatologia dos edemas na hanseníase.

  10. Performance of the 2-D asynchronous OCDMA system with ASE light sources

    2005-09-01

    The wavelength-hopping/time-spreading scheme for optical code-division multiple-access (OCDMA), also known as the 2-D scheme, has been studied by many researchers for more than a decade. In all of previous analyses, the light sources were modeled as perfectly incoherent, which requires infinite bandwidth, and chip-synchrony was assumed for mathematical simplicity. Therefore, it is important to study how the system actually performs with true asynchrony and practical light sources. The amplified spontaneous emission (ASE) source is a desirable source for the incoherent OCDMA system because of its broad bandwidth, large power, and low cost. In this paper, each chip generated by the transmitter is a rectangular ASE pulse with a Gaussian-distributed electrical field. The coherence time is much smaller than the chip duration, but non-zero. Because of this partial coherence of the light source, beat noise will occur when multiple pulses are combined. In addition, interfering pulses may only partially overlap with the pulses from the desired user due to the asynchrony, which introduces more randomness into the decision statistic. Both factors are taken into account when the distribution of the decision statistic is derived mathematically. Simulations of the bit-error rate (BER) are performed, and the results show that the coherence time may be the major limiting factor on the system performance. For example, when the coherence time is only 1/100 of the chip duration, the BER is 1-4 orders of magnitude worse than that of the ideal case.

    Full Text Available The replacement of conventional sample preparation techniques with newer techniques which are automated, faster and more eco-friendly, is nowadays desired in every analytical laboratory. One of the techniques with the attributes mentioned above is the Accelerated Solvent Extraction. In order to evaluate how successful this method is for the extraction of fat and organochlorine pesticides (OCPs from dried fish meat samples, we have tested two series of diverse fish using Dionex™ 350 ASE provided by Thermo Scientific™ (Germany. For a more interesting approach, we added to our investigation 7 polychlorinated biphenyl (PCBs, 3 thricholorobenzenes, 2 tetrachlorobenzenes, 1 pentachlorobenzenes and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD. The study focused on comparing the recoveries of these analytes from different fish samples, after replacing the conventional reference method of the laboratory with ASE. The ASE parameters tested were previously used for the extraction of fat and polybrominated diphenyl ethers (PBDE from fish samples: temperature: 120 ° C; static time: 5 min; number of cycles: 3; flushing volume: 25%; rinse with nitrogen: 90 s; solvent: cyclohexane/ethyl acetate (ratio 1:1. The ASE method provided similar and in some cases better results when compared to the standard reference method, more rapidly, eco-friendly and safer. Any high or low recoveries of the analytes taken into study are attributed to random or systematic errors during the Clean-up step of the extracts and the quantification with Gas Chromatography coupled with Tandem Mass-Spectrometry (GC MS/MS.

  8. SAIL: Summation-bAsed Incremental Learning for Information-Theoretic Text Clustering.

    Cao, Jie; Wu, Zhiang; Wu, Junjie; Xiong, Hui

    2013-04-01

    Information-theoretic clustering aims to exploit information-theoretic measures as the clustering criteria. A common practice on this topic is the so-called Info-Kmeans, which performs K-means clustering with KL-divergence as the proximity function. While expert efforts on Info-Kmeans have shown promising results, a remaining challenge is to deal with high-dimensional sparse data such as text corpora. Indeed, it is possible that the centroids contain many zero-value features for high-dimensional text vectors, which leads to infinite KL-divergence values and creates a dilemma in assigning objects to centroids during the iteration process of Info-Kmeans. To meet this challenge, in this paper, we propose a Summation-bAsed Incremental Learning (SAIL) algorithm for Info-Kmeans clustering. Specifically, by using an equivalent objective function, SAIL replaces the computation of KL-divergence by the incremental computation of Shannon entropy. This can avoid the zero-feature dilemma caused by the use of KL-divergence. To improve the clustering quality, we further introduce the variable neighborhood search scheme and propose the V-SAIL algorithm, which is then accelerated by a multithreaded scheme in PV-SAIL. Our experimental results on various real-world text collections have shown that, with SAIL as a booster, the clustering performance of Info-Kmeans can be significantly improved. Also, V-SAIL and PV-SAIL indeed help improve the clustering quality at a lower cost of computation.

    The response of broiler chickens to 3 levels of sunflower meal and 2 levels of NSP-ase enzyme combination (with and without) was investigated in 3 × 2 factorial arrangement under complete randomized design (CRD). A total of 240 Hubbard broiler chicks were fed on practical mash diets having 2950 kcal of ME and 21% CP from 1 to 42 days of age. The BW gain was not significantly reduced when 25% SFM was added in the diets during 1 to 42 days of age. Supplementation of NSP-ase in broiler diets (day 1-42 overall) demonstrated non-significant differences (p Replacement of SBM with SFM or inclusion of SFM at higher level (25%) increased/deteriorated FCR. The addition of exogenous NSP-ase showed a significant improvement (p < 0.01) in feed:gain. The improvement was clearly demonstrated when SFM was added to the experimental diet at 15% or even 20%. Supplementation of NSP-ase at the 25% inclusion level could not, however, sustain the beneficial effect, which was possibly due to excessively high dietary CF. No difference was noted across the treatments regarding carcass response. Relative gizzard weight and intestinal weight were observed to be improved in birds consuming higher levels of SFM (p = 0.00). The digestibility of CF was observed to improve when SFM was used at 20% and 25% in the diets. No improvement in the digestibility of CF was observed with NSP-ase supplementation, which meant other factors were clearly involved. Supplementation of NSP-ase improved FCR up to 20% SFM. At 25% SFM, no improvement in the digestibility of CF was observed with NSP-ase supplementation. Journal of Animal Physiology and Animal Nutrition © 2016 Blackwell Verlag GmbH.

    PAF-ase is a specific serum enzyme that inactivates PAF by hydrolyzing acetate from the sn-2 position of the glycerol backbone. A reproducible PAF-ase activity assay was developed. A unit is based on the amount of serum required to release 3.61 +/- 0.042 pm 3 H-acetate from 10 pm 3 H-labeled PAF after incubation for 1 hr at 37 0 C. Assays on two single reference serums repeated 7 days were 0.63 +/- 0.013 U and 1.33 +/- 0.031 U. Serum from 20 normal men and 20 normal premenopausal women had significantly different (p = <0.001) levels of 1.32 +/- 0.072 U and 0.97 +/- 0.051 U respectively. They previously reported that PAF-ase is associated with B-lipoprotein. Therefore, total cholesterol (TC), LDL and high density lipoproteins (HDL) were determined on these 40 serums. Regression analysis revealed PAF-ase units were correlated with LDL (r = 0.740; p = < 0.001) and, parenthetically, with the TC (r = 0.620; p = < 0.001) but not with HDL. These correlations were similar for men and women. Thus, serum PAF-ase was partially controlled by serum LDL levels and the higher PAF-ase levels in serum from men were due in part to higher (p = < 0.01) LDL levels in men (147.6 +/- 6.9 mg/dl) as contrasted to women (119.0 +/- 7.6 mg/dl). PAF is a potent inflammatory, bronchoconstrictive and hypotensive agent. These data indicate that sex and serum LDL levels of subjects must be considered during future studies of the role of PAF vs PAF-ase in different disease states

    The SG-1 FEL facility is composed of a linear induction accelerator (LIA), an electron beam transport system, a wiggler, a microwave source and a diagnostic system. SG-1 LIA provides a 2 kA, 3.0 MeV beam with a normalized emittance of 0.4∼0.6 (π rad·cm), an energy spread (FWHM) of 4%, resulting in a beam brightness of nearly 10 8 A/πm·rad) 2[1] . The beam current through the wiggler is about 600 A. The first ASE experiments began in September 1991. A 2.6-m long wiggler with a peak magnetic field of 0.3 T was used. At 35.8∼36.5 GHz an ASE output of 0.5 W was obtained for a beam current of nearly 50 A. After a shutdown of about 8 months, the second series of ASE experiments began in October 1992. The second series of ASE experiments were performed with a wiggler magnetic field between 0.25∼0.27 T. The maximum output power is about 100 kw for B w = 0.24 T, I = 600 A, At ν = 35.2 GHz. Based on the ASE experiments the amplifier experiments was carried out on SG-1. Using an 300 W input signal (TE 01 ), a beam current of about 600 A and wiggler magnetic fields of 0.24∼0.28 T, the authors measured the FEL output power as a function of the wiggler magnetic field. The resonant magnetic field was about 0.25 T. Meanwhile, in order to study the amplifier gain, the authors measured the FEL output power as a function of the wiggler length at a peak wiggler magnetic field of 0.26 T. The exponential gain is approximately 19 dB/m and the maximum output power is about 10 MW

It has been shown that calixarene С-107 reduced the Na+,K+-АТРase activity more efficiently than ouabain did, while it did not practically influence the “basal” Mg2+-АТРase activity of the same membrane. The magnitude of the cofficient of inhibition I0.5 was 33 ± 4 nМ, Hill coefficient was 0.38 ± 0.06. The model calixa­rene C-150 – the calixarene “scaffold” (26,28-dihydroxy-25,27-dipropoxycalix[4]arene, and the model compound М-3 (4-hydroxyaniline(2-pyridinemethylphosphonic acid – a fragment of the calixarene С-107, had practically no influence on the enzymatic activity of Na+,K+-АТРase and Mg2+-АТРаse. We carried out the computer simulation of interaction of calixarenes C-107 and the mentioned model compound with ligand binding sites of the Na+,K+-АТРase of plasma membrane and structure foundation of their intermolecular interaction was found out. The participation of hydrogen, hydrophobic, electrostatic and π-π (stacking interaction between calixarene and enzyme aminoacid residues, some of which are located near the active center of Na+,K+-АТРase, was discussed.

    Full Text Available Background: It is known that Na+,K+-ATP-ase plays important role in physiology of spermatozoa including their motility. Na+,K+-ATP-ase is one of the targets for reactive oxygen species. Hyperproduction of reactive oxygen species can damage sperm cells and it is considered to be as one of the mechanisms of male infertility. Objectives: To evaluate the H2O2 effect on the main kinetic parameters of ATP hydrolysis by ouabain-sensitive Na+,K+-ATPase of spermatozoa of fertile (normozoospermia and infertility men (asthenozoospermia. Materials and methods: Na+, K+-ATP-ase activity was determined spectrophotometrically by production of Pi. Concentration dependencies ware linearized in Lineweaver-Burk plot. Results: Effective inhibitory effect of H2O2 on ouabain-sensitive Na+,K+-ATP-ase activity of sperm cells of fertile and infertile men was demonstrated. The effects of H2O2 on the main kinetic parameters of the ATP hydrolysis with the involvement of Na+, K+-ATP-ase was studied. In the whole range of studied concentrations of ATP the Na+, K+-ATP-ase activity of spermatozoa of fertile and infertile men was reduced in the presence of H2O2 in the incubation medium. However, the optimal activity of the Na+, K+-ATP-ase activity of sperm cells in both normozoospermic and asthenozoospermic men was observed in the presence of 5 mM ATP in the incubation medium. By linearization of concentration curves in Lineweaver-Burk plot the main kinetic parameters of Na+, K+-activated, Mg2+-dependent ATP hydrolysis in the sperm cells of fertile and infertile men were determined. Under the effect of H2O2, the affinity constant of enzyme to ATP in normozoospermic and asthenozoospermic men increases several times. The initial maximum rate of ATP hydrolysis was significantly reduced only in the spermatozoa of fertile men with normozoospermia. Conclusions: Under conditions of H2O2-induced oxidative stress the inhibition of ouabain-sensitive Na+,K+-ATP-ase activity in sperm cells

    Since lipids are depleted in 13 C relative to proteins and carbohydrates, variations in lipid composition among species and within individuals significantly influence δ 13 C and may result in misleading ecological interpretations. Whereas lipid extraction before IRMS analysis constitutes a way of stable isotope result lipid-normalisation, such a procedure was given up because of the un-controlled effects of the methods used (i.e., 'Bligh and Dyer', Soxhlet, etc.) on δ 15 N. The aim of this work was to develop a simple, rapid and efficient lipid extraction method allowing for simultaneous C and N stable isotope analysis in the biological soft tissues of aquatic organisms. The goal was to be free from the lipid influence on δ 13 C values without interfering with δ 15 N values. For that purpose, the modern automated pressurized liquid extraction technique ASE (accelerated solvent extraction) was selected. Eel muscles representative of a broad range of fat contents were extracted via ASE by using different semi-polar solvents (100% dichloromethane and 80% n-hexane/20% acetone) and by operating at different temperature (ambient temperature and 100 deg. C) and pressure (750 and 1900 psi) conditions. The results were discussed in terms of lipid extraction efficiency as well as δ 13 C and δ 15 N variability.

    Purpose: A retrospective clinical-histological study to determine the diagnostic accuracy using high-resolution digital phosphor storage plates (CR) (hardcopy) and full-field digital mammography (DR) (hardcopy) for microcalcifications and focal lesions (BI-RADS category 4 or 5) (n=100). Materials and Methods: From 01/2004 to 06/2004, 100 patients underwent digital storage plate mammography (CR) and, after diagnosis and preoperative wire localization, full-field digital mammography (a-Se) (DR) with the same exposure parameters. Five investigators retrospectively determined the diagnosis after the operation from randomly distributed mediolateral views (hardcopy reading). These results were correlated with the final histology. Results: The accuracy of digital storage plate mammography (CR) and full-field digital mammography (DR) was 73% and 76% for all findings (n=100), 74%, 78% for microcalcifications (n=50) and 72%, 74% for focal lesions (n=50). The overall results showed no difference. Conclusion: Our findings indicate equivalence of high-resolution digital phosphor storage plate mammography (CR) and full-field digital mammography (a-Se) (DR). (orig.)

    We report an image wavelength upconversion system. The system mixes an incoming image at around 1550 nm (eye-safe region) illuminated by an amplified spontaneous emission (ASE) fiber source with a Gaussian beam at 1064 nm generated in a continuous-wave diode-pumped Nd(3+):GdVO(4) laser. Mixing takes place in a periodically poled lithium niobate (PPLN) crystal placed intra-cavity. The upconverted image obtained by sum-frequency mixing falls around the 631 nm red spectral region, well within the spectral response of standard silicon focal plane array bi-dimensional sensors, commonly used in charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) video cameras, and of most image intensifiers. The use of ASE illumination benefits from a noticeable increase in the field of view (FOV) that can be upconverted with regard to using coherent laser illumination. The upconverted power allows us to capture real-time video in a standard nonintensified CCD camera.

    Full Text Available Médica, doutora em patologia, Euzenir Sarno é estudiosa da imunopatologia da hanseníase, infecção crônica das mais antigas que constitui uma doença exclusivamente humana. Integrante de um dos ambulatórios de referência sobre a doença no Brasil, no qual são diagnosticados de 220 a 250 pacientes novos/ano, ressalta que uma das conseqüências da impossibilidade de se cultivar o Mycobacterium leprae é a permanência das mesmas questões seculares a respeito da transmissão e a suscetibilidade à doença. Há, também, muitas interrogações no terreno epidemiológico que permanecem sem resposta. Estima-se que entre as pessoas que mantêm contato com pacientes multibacilares, 90% são infectados mas apenas 8% mais ou menos ficam doentes. O índice elevado de infecção de quem convive com doentes multibacilares, sem que a doença se manifeste, indica que apenas um pequeno número de indivíduos não tem resistência ao Mycobacterium leprae. Essa é uma das questões que a imunologia não consegue responder: por que algumas pessoas têm resistência e outras não. A proporção é menor se o contato ocorrer com pacientes paucibacilares, uma forma de manifestação com poucos bacilos. A hanseníase é conhecida como uma doença dermatológica, mas a especialista destaca que a primeira lesão é anestésica: o nervo é atingido. Além dos nervos sensitivos da pele, há danos que determinam lesões motoras e deformidades irreversíveis, que levam à amputação de extremidades. O Mycobacterium leprae foi uma das primeiras bactérias patogênicas que tiveram o genoma completamente seqüenciado, em 2000. Agora é que se está começando a ter realmente condições para obter testes mais precisos. A doença não é hereditária e apenas em 1986 os serviços de saúde no Brasil passaram a se organizar para combatê-la, pois durante os vinte anos de ditadura militar o sistema foi desmantelado. Em 1991, o tratamento de um ano que inclui tr

    The bahviour of a Mg 2+ -dependent, Na + - and K + -activable ATP-ase sytem on irradiation was investigated using a microsome fraction of guinea pig myocardial cells prepared by fractionated centrifugation. The Na + - and K + -activable component, transport-ATPase, was particularly radiation-sensitive. Three stages of development were observed for a 1,500 R radiation damage until 24 h p.r.. In the first stage, until 30 minutes p.r., the activity of transport-ATP-ase was inhibited. This was followed by repair processes which had reached a peak value clearly higher than the control values at 4 hours p.r.. In the third stage, the activity was reduced again; 15 and 24 hours after termination of exposure, values again were nearly the same as after 30 minutes where a maximum was observed for this radiation dose. Radiation-induced electrolyte displacements, active transport, and radiation-induced inhibition of transport-ATP-ase were correlated and discussed; the assumption was that changes in, the electrolyte conditions in the membranes on irradiation are at least partly due to the described inhibition of transport-ATP-ase.

    Full Text Available Multidrug therapy (MDT, with rifampicin, dapsone, and clofazimine, treats leprosy infection but is insufficient in arresting or preventing the nerve damage that causes impairments and disabilities. This case-series study evaluates the benefits of the combined use of steroids and MDT in preventing nerve damage in patients with pure neural leprosy (PNL. In addition to MDT, 24 patients (88% male aged 20-79 years, median=41 received a daily morning dose of 60 mg prednisone (PDN that was gradually reduced by 10 mg during each of the following 5 months. PNL was clinically diagnosed and confirmed by nerve histopathology or PCR. A low prevalence (8.3% of reaction was observed after release from treatment. However, most of the clinical parameters showed significant improvement; and a reduction of nerve conduction block was observed in 42% of the patients. The administration of full-dose PDN improved the clinical and electrophysiological condition of the PNL patients, contributing to the prevention of further neurological damage.A poliquimioterapia (PQT, com rifampicina, dapsona, e clofazimina, trata a infecção na hanseníase, mas é insuficiente para interromper ou prevenir o comprometimento neurológico que causa as incapacidades e desabilidades, nesta enfermidade.

    1999-09-01

    Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos. A infecção em humanos é acidental e ocorre pela ingestão de secreção mucóide destes invertebrados presentes em vegetais ou por contato direto com o muco. A angiostrongilíase abdominal é clinicamente caracterizada pela presença de febre prolongada, anorexia, dor no quadrante inferior direito do abdômen e eosinofilia periférica. Embora a doença seja de

  15. Conformational changes in DNA caused by DNA-ase I, gamma and ultraviolet radiation as revealed by differential pulse polarography

    International Nuclear Information System (INIS)

    Vorlickova, M.

    1979-01-01

    The height, potential and half width of differential pulse-polarographic peaks of DNA were investigated in dependence on degradation by DNA-ase I and gamma and UV radiation. It was found that in all cases studied growth of peak II (reflecting conformational changes in the DNA double helix) was limited, and only after it reached a certain height further degradation induced the appearance of peak III of single-stranded DNA. This course is explained as reflecting the limited extent of conformational changes in the framework of the double helix, which probably follows from a limited number of sites that can undergo certain types of conformational changes. The character of the conformational changes is dependent on the chemical nature of the damage. (author)

    The presence of a natural inhibitor of DNAase 1 of protein nature is responsible for the inhibiting action of blood serum on pancreatic DNAase. Depending on the radiation dose (ranging from 450 to 750 R), the activity of the serum inhibitor of DNAase 1 increases for a short time, then, in the period from 15 minutes to 24 hours, it normalizes (450 R) or drastically decreases on the seventh day (750 R). At the dose of 750 R, the activity of free serum DNAase 1 increases throughout the entire period of the experiment; the activity of bound DNAase 1 gradually decreases and it is not observed on the seventh day. The dose of 450 R does not substantially affect the activity of free DNAase 1. Evidently, at high X-ray doses, formation of the inhibitor-serum DNAase 1 complex is disturbed

    The aim of the current study was to validate the self-report section of the American Shoulder and Elbow Surgeons questionnaire (ASES-p) into Spanish. Shoulder pathology patients were recruited and followed up to 6 months post treatment. The ASES-p, Constant, SF-36 and Barthel scales were filled-in pre and post treatment. Reliability was tested with Cronbach's alpha, convergent validity with Spearman's correlations coefficients. Confirmatory factor analysis (CFA) and the Rasch model were implemented for assessing structural validity and unidimensionality of the scale. Models with and without the pain item were considered. Responsiveness to change was explored via standardised effect sizes. Results were acceptable for both tested models. Cronbach's alpha was 0.91, total scale correlations with Constant and physical SF-36 dimensions were >0.50. Factor loadings for CFA were >0.40. The Rasch model confirmed unidimensionality of the scale, even though item 10 "do usual sport" was suggested as non-informative. Finally, patients with improved post treatment shoulder function and those receiving surgery had higher standardised effect sizes. The adapted Spanish ASES-p version is a valid and reliable tool for shoulder evaluation and its unidimensionality is supported by the data.

    Using the ASED-MO (Atom Superposition and Electron Delocalization-Molecular Orbital) theory, we investigated carbon formation and carbon hydrogenation for CO_2 methanation on the Ni (111) surface. For carbon formation mechanism, we calculated the following activation energies, 1.27 eV for CO_2 dissociation, 2.97 eV for the CO, 1.93 eV for 2CO dissociation, respectively. For carbon methanation mechanism, we also calculated the following activation energies, 0.72 eV for methylidyne, 0.52 eV for methylene and 0.50 eV for methane, respectively. We found that the calculated activation energy of CO dissociation is higher than that of 2CO dissociation on the clean surface and base on these results that the CO dissociation step are the ratedetermining of the process. The C-H bond lengths of CH_4 the intermediate complex are 1.21 A, 1.31 A for the C···H_(_1_), and 2.82 A for the height, with angles of 105 .deg. for H_(_1_)CH and 98 .deg. for H_(_1_)CH_(_1_)

Ao discorrer sobre o engajamento do Brasil no programa lançado pela Organização Mundial de Saúde, Tadiana explica que o objetivo da OMS é eliminar a hanseníase até 2005. No entanto, ela diz que a meta brasileira é, neste prazo, reduzir a incidência da doença a até menos de um caso por dez mil pessoas. Em nosso país, a estrutura e organização de tal programa, que engloba desde a formação e especialização de profissionais para garantir o diagnóstico precoce, ao acompanhamento do paciente durante o tratamento, é realizado pelo Sistema Único de Saúde (SUS, implantado em todos os estados da federação. O tratamento poliquimioterápico dura, em média, um ano, se for seguido à risca. Em muitos casos, a doença volta a se manifestar posteriormente. Ela comenta as diferenças de incidência da hanseníase, dependendo da região: já foi eliminada em dois dos três estados do Sul do país, ao passo que em estados do Norte e Centro-Oeste atinge índices hiperendêmicos. Trabalhando em estreita articulação com as associações de pacientes e ex-pacientes, inicialmente como enfermeira e, depois, na implantação das políticas de atenção ao hanseniano, Tadiana Alves Moreira fala sobre a importância do diagnóstico precoce visando evitar seqüelas físicas que a doença provoca quando alcança estágios avançados, e assim, reduzir o estigma que recai sobre os seus portadores.The interviewee speaks about the endemic disease, which at present contaminates 4.4 out of ten thousand inhabitants in Brazil, the country with the second highest number of patients.

    Full Text Available Por meio da etofamida, trataram os autores 40 indivíduos acometidos de amebíase intestinal e representados por crianças e adultos de ambos os sexos. Os esquemas posológicos recomendados para os componentes de dois grupos de 20 elementos foram os seguintes: A 100 mg três vezes em 24 horas, durante cinco dias; B 100 mg, cinco vezes em 24 horas, durante três dias. Foi expressiva a percentagem global de 90% de curas obtidas, mas a administração de maior quantidade diária da droga, durante período mais curto, mostrou-se dotada de melhor efetividade e possibilitou a eliminação da parasitose de todas as pessoas medicadas. O estudo que efetuaram, correspondente à amebíase intestinal assintomática, oligossintomática ou aparente como colite crônica, deixou patente a eficácia do remédio usado, que praticamente não causou distúrbios colaterais e pode ser prescrito segundo planejamentos singelos e executáveis com facilidade.

    Full Text Available A microlitíase alveolar pulmonar (MAP é uma doença rara que atinge ambos os pulmões, caracterizada pela presença de pequenos cálculos (fosfato de cálcio nos espaços alveolares. Relatamos o caso de uma paciente do sexo feminino, de 26 anos, cujo diagnóstico foi confirmado com base nos achados marcantes na radiografia de tórax e tomografia computadorizada de alta resolução. A paciente, gestante de 28 semanas, retornou ao hospital 10 meses após o diagnóstico apresentando insuficiência respiratória hipoxêmica e com distúrbio ventilatório restritivo grave à espirometria. Após completadas 32 semanas e 4 dias de gestação, foi submetida aparto cesariano, com sucesso para mãe e filha. A MAP tem evolução clínica variável. Tem provável caráter autossômico recessivo e associação com história familiar positiva. A etiologia é incerta, e muitos autores especulam que haja um defeito enzimático local responsável pelo acúmulo intra-alveolar de cálcio. Relatos de pacientes com MAP que engravidaram são excepcionais, sendo o presente caso o primeiro descrito no Brasil. O curso dessa doença costuma ser lentamente progressivo, e os pacientes geralmente falecem devido à insuficiência cardiorrespiratória. O presente caso ilustra a necessidade de se oferecer aconselhamento genético e orientações sobre o risco de gravidez às pacientes, especialmente em casos de doença avançada.

    Broadband output from 1060nm to 1700nm and cascaded four-wave mixing generated red light pulsing is observed in a fiber amplifier set up consisting of a 5.5m double clad, double D shaped Ytterbium doped fiber, a single clad passive fiber for excess pump absorption and a splitter, both with and without a CW seed. Self-pulsing occurs from ASE due to passive Q-switching by saturable absorption effect of the active fiber and also depends on splice loss. The pulses generate broadband output by multiple four-wave mixing process with maximum broadening efficiency near 1300nm which is the zero dispersion wavelength for silica fiber. Pulses traveling both in forward and backward direction have enough peak power and energy to damage splice points and fiber components. When seeded the self-pulsing and broadband generation is often suppressed but again generate at increased pump powers.

    For sustainable growth of the Internet, wavelength-tunable optical regeneration is the key to scaling up high energy-efficiency dynamic optical path networks while keeping the flexibility of the network. Wavelength-tunable optical parametric regenerator (T-OPR) based on the gain saturation effect of parametric amplification in a highly nonlinear fiber is promising for noise reduction in phase-shift keying signals. In this paper, we experimentally evaluated the T-OPR performance for ASE-degraded 43-Gb/s RZ-DPSK signals over a 20-nm input wavelength range between 1527 nm and 1547 nm. As a result, we achieved improved power penalty performance for the regenerated idler with a proper pump power range.

    The authors describe a detailed Monte Carlo (MC) method for the coupled transport of ionizing particles and charge carriers in amorphous selenium (a-Se) semiconductor x-ray detectors, and model the effect of statistical variations on the detected signal. A detailed transport code was developed for modeling the signal formation process in semiconductor x-ray detectors. The charge transport routines include three-dimensional spatial and temporal models of electron-hole pair transport taking into account recombination and trapping. Many electron-hole pairs are created simultaneously in bursts from energy deposition events. Carrier transport processes include drift due to external field and Coulombic interactions, and diffusion due to Brownian motion. Pulse-height spectra (PHS) have been simulated with different transport conditions for a range of monoenergetic incident x-ray energies and mammography radiation beam qualities. Two methods for calculating Swank factors from simulated PHS are shown, one using the entire PHS distribution, and the other using the photopeak. The latter ignores contributions from Compton scattering and K-fluorescence. Comparisons differ by approximately 2% between experimental measurements and simulations. The a-Se x-ray detector PHS responses simulated in this work include three-dimensional spatial and temporal transport of electron-hole pairs. These PHS were used to calculate the Swank factor and compare it with experimental measurements. The Swank factor was shown to be a function of x-ray energy and applied electric field. Trapping and recombination models are all shown to affect the Swank factor.

  13. A microfabricated, low dark current a-Se detector for measurement of microplasma optical emission in the UV for possible use on-site

    Traditionally, samples are collected on-site (i.e., in the field) and are shipped to a lab for chemical analysis. An alternative is offered by using portable chemical analysis instruments that can be used on-site (i.e., in the field). Many analytical measurements by optical emission spectrometry require use of light-sources and of spectral lines that are in the Ultra-Violet (UV, ~200 nm - 400 nm wavelength) region of the spectrum. For such measurements, a portable, battery-operated, fiber-optic spectrometer equipped with an un-cooled, linear, solid-state detector may be used. To take full advantage of the advanced measurement capabilities offered by state-of-the-art solid-state detectors, cooling of the detector is required. But cooling and other thermal management hamper portability and use on-site because they add size and weight and they increase electrical power requirements. To address these considerations, an alternative was implemented, as described here. Specifically, a microfabricated solid-state detector for measurement of UV photons will be described. Unlike solid-state detectors developed on crystalline Silicon, this miniaturized and low-cost detector utilizes amorphous Selenium (a-Se) as its photosensitive material. Due to its low dark current, this detector does not require cooling, thus it is better suited for portable use and for chemical measurements on-site. In this paper, a microplasma will be used as a light-source of UV photons for the a-Se detector. For example, spectra acquired using a microplasma as a light-source will be compared with those obtained with a portable, fiber-optic spectrometer equipped with a Si-based 2080-element detector. And, analytical performance obtained by introducing ng-amounts of analytes into the microplasma will be described.

    The risk of sporadic colorectal cancer is mainly associated with lifestyle factors and may be modulated by several genetic factors of low penetrance. Genetic variants represented by single nucleotide polymorphisms in genes encoding key players in the adenoma carcinoma sequence may contribute to variation in susceptibility to colorectal cancer. In this study, we aimed to evaluate whether the recently identified haplotype encompassing genes of DNA repair and apoptosis, is associated with increased risk of colorectal adenomas and carcinomas. We used a case-control study design (156 carcinomas, 981 adenomas and 399 controls) to test the association between polymorphisms in the chromosomal region 19q13.2-3, encompassing the genes ERCC1, ASE-1 and RAI, and risk of colorectal adenomas and carcinomas in a Norwegian cohort. Odds ratio (OR) and 95% confidence interval (CI) were estimated by binary logistic regression model adjusting for age and gender. The ASE-1 polymorphism was associated with an increased risk of adenomas, OR of 1.39 (95% CI 1.06–1.81), which upon stratification was apparent among women only, OR of 1.66 (95% CI 1.15–2.39). The RAI polymorphism showed a trend towards risk reduction for both adenomas (OR of 0.70, 95% CI 0.49–1.01) and carcinomas (OR of 0.49, 95% CI 0.21–1.13) among women, although not significant. Women who were homozygous carriers of the high risk haplotype had an increased risk of colorectal cancer, OR of 2.19 (95% CI 0.95–5.04) compared to all non-carriers although the estimate was not statistically significant. We found no evidence that the studied polymorphisms were associated with risk of adenomas or colorectal cancer among men, but we found weak indications that the chromosomal region may influence risk of colorectal cancer and adenoma development in women

    Full Text Available OBJETIVO: Considerando a alta freqüência da colelitíase no paciente pediátrico com doença falciforme e a controvérsia na literatura sobre a abordagem da condição, o presente texto objetiva revisar a literatura disponível. FONTE DE DADOS: Revisão dos estudos sobre colelitíase no paciente falciforme, publicados no período entre 1980 e 2007, em língua inglesa e portuguesa, envolvendo pacientes na faixa etária de zero a 18 anos e utilizando os bancos de dados Medline e Lilacs. SÍNTESE DOS DADOS: A colelitíase é a complicação digestiva mais comum no paciente falciforme e sua incidência aumenta com a faixa etária. Os mecanismos fisiopatológicos são conhecidos, assim como os métodos diagnósticos. A conduta terapêutica consensual na colelitíase sintomática é a colecistectomia, preferencialmente por via laparoscópica. Nos casos assintomáticos, a maioria dos autores recomenda a conduta cirúrgica, para evitar complicações, confusão no diagnóstico diferencial de dor abdominal futura e menor risco cirúrgico. Contudo, não existe consenso na literatura, havendo base para a adoção de conduta expectante. CONCLUSÕES: A doença falciforme tem grandes variações em sua apresentação clinica, história natural e gravidade da hemólise. Algumas populações podem apresentar menor freqüência de colelitíase e menor número de pacientes sintomáticos, possivelmente em razão de variações de haplótipos, fatores ambientais e diferentes manejos clínicos. Ainda não existem dados suficientes na literatura ou estudos randomizados e controlados que possibilitem definir o momento ideal para a colecistectomia no paciente falciforme com litíase assintomática. Dessa maneira, dependendo de características individuais e da população, podem ser aceitos o seguimento clínico ou a indicação precoce de colecistectomia.OBJECTIVE: Given the high frequency of cholelithiasis in children with sickle cell disease and the controversies

    Full Text Available O encontro de parasitos em material arqueológico tem permitido o acompanhamento da dispersão de agentes infecciosos e seus hospedeiros humanos no passado. Através desses achados, pôde-se retomar teorias propostas no início do século sobre contatos transpacíficos de populações asiáticas com a América do Sul. Assim foi feito, por exemplo, no caso do encontro de ovos de ancilostomídeos em material arqueológico datado de até sete mil anos antes do presente. O aumento da produção científica na área torna necessária, agora, a realização de trabalhos de síntese que avaliem o estado da arte e proponham modelos paleoepidemiológicos compreensíveis para a dispersão pré-histórica das parasitoses humanas. Nesse sentido, foi feito o presente trabalho, a partir dos recentes achados de ovos de Enterobius vermicularis em material arqueológico nas Américas. Diferentemente da infecção por ancilostomídeos, a oxiuríase não necessita de passagem pelo solo para a transmissão de um hospedeiro a outro, logo, sua persistência em uma dada população humana independe das condições climáticas. Poderia, portanto, ter sido trazida do velho para o novo continente, inclusive pelas migrações humanas que atravessaram o estreito de Bering. Tal fato pode explicar a maior dispersão geográfica dos achados e sua disseminação na América do Norte, desde dez mil anos até os tempos atuais. Na América do Sul, por outro lado, os achados arqueológicos só confirmaram sua existência ao longo da região andina, com achados no Chile e no Norte da Argentina. No Brasil, apesar do grande número de amostras examinadas, não foram encontrados ovos de Enterobius vermicularis em coprólitos. No presente trabalho, discutem-se modelos explicativos para a distribuição conhecida dessa parasitose em populações pré-históricas.Parasite findings in archeological material have made it possible to trace the dispersion of infectious agents and their human

    Purpose: To evaluate the task specific imaging performance of a new 25µm pixel pitch, 1000µm thick amorphous selenium direct detection system with CMOS readout for typical angiographic exposure parameters using the relative object detectability (ROD) metric. Methods: The ROD metric uses a simulated object function weighted at each spatial frequency by the detectors’ detective quantum efficiency (DQE), which is an intrinsic performance metric. For this study, the simulated objects were aluminum spheres of varying diameter (0.05–0.6mm). The weighted object function is then integrated over the full range of detectable frequencies inherent to each detector, and a ratio is taken of the resulting value for two detectors. The DQE for the 25µm detector was obtained from a simulation of a proposed a-Se detector using an exposure of 200µR for a 50keV x-ray beam. This a-Se detector was compared to two microangiographic fluoroscope (MAF) detectors [the MAF-CCD with pixel size of 35µm and Nyquist frequency of 14.2 cycles/mm and the MAF-CMOS with pixel size of 75µm and Nyquist frequency of 6.6 cycles/mm] and a standard flat-panel detector (FPD with pixel size of 194µm and Nyquist frequency of 2.5cycles/mm). Results: ROD calculations indicated vastly superior performance by the a-Se detector in imaging small aluminum spheres. For the 50µm diameter sphere, the ROD values for the a-Se detector compared to the MAF-CCD, the MAF-CMOS, and the FPD were 7.3, 9.3 and 58, respectively. Detector performance in the low frequency regime was dictated by each detector’s DQE(0) value. Conclusion: The a-Se with CMOS readout is unique and appears to have distinctive advantages of incomparable high resolution, low noise, no readout lag, and expandable design. The a-Se direct detection system will be a powerful imaging tool in angiography, with potential break-through applications in diagnosis and treatment of neuro-vascular disease.

Results: ROD calculations indicated vastly superior performance by the a-Se detector in imaging small aluminum spheres. For the 50µm diameter sphere, the ROD values for the a-Se detector compared to the MAF-CCD, the MAF-CMOS, and the FPD were 7.3, 9.3 and 58, respectively. Detector performance in the low frequency regime was dictated by each detector’s DQE(0) value. Conclusion: The a-Se with CMOS readout is unique and appears to have distinctive advantages of incomparable high resolution, low noise, no readout lag, and expandable design. The a-Se direct detection system will be a powerful imaging tool in angiography, with potential break-through applications in diagnosis and treatment of neuro-vascular disease.

    Full Text Available Hepatobiliary alterations found in an autopsy case of massive Biliary Ascariasis, are reported on histological grounds. Severe cholangitis was the main finding, but other changes were also detected, such as pyloric and intestinal metaplasia, hyperplasia of the epithelial lining, with intraductal papillomas and adenomatous proliferation. Remnants of the worm were observed tightly adhered to the epithelium, forming microscopic intrahepatic calculi. Mucopolysaccharides, especially acid, showed to be strongly positive on the luminal border, and in proliferated glands around the ducts. The authors discuss the similarity between such findings and Oriental Cholangiohepatitis, and suggest that inflammation and the presence of the parasitic remnants are responsible for the hyperplastic and metaplastic changes, similarly with what occurs in chlonorchiasis, fascioliasis and schistosomiasis.Os autores apresentam os aspectos histopatológicos encontrados no fígado de um caso de autópsia de Ascaridíase Biliar maciça. A intensa colangite foi o aspecto predominante, mas outras lesões também foram encontradas, tais como metaplasia pilórica e intestinal, hiperplasia epitelial com papilomas intraductais, e por vezes padrão adenomatoso. Restos do helminto foram encontrados fortemente aderidos ao epitélio, sendo intensa a positividade de mucopolissacárides, principalmente ácidos, na borda luminal do epitélio ductal e em glândulas proliferadas ao redor dos ductos. Os autores discutem a semelhança da Ascaridíase Biliar com a Colangio Hepatite Oriental, e sugerem que o processo inflamatório e a presença de restos do verme são responsáveis pelas alterações hiperplásicas e metaplásicas, analogamente ao que ocorre na clonorquíase, fasciolíase e esquistossomose.

    Full Text Available Este estudo analisa as representações sociais da hanseníase em São Domingos do Capim-PA, a partir da perspectiva da antropologia da doença. As representações são compreendidas como estruturas dinâmicas socialmente construídas que fundamentam as ações dos sujeitos e dos grupos na resolução dos episódios de doença e na produção de sentido para as experiências de adoecimento. Para compreender a lógica das interpretações da doença, foram reconstituídos os itinerários terapêuticos dos doentes, a partir de dados coletados na observação de campo, realizada ao longo de quatro anos, e entrevistas narrativas com doentes, familiares e agentes comunitários de saúde. Foram deduzidas quatro categorias nosológicas êmicas referentes aos sintomas da hanseníase - "manchas", "lepra", "feitiço" e "hanseníase" -, que constituem o repertório a partir do qual as interpretações e práticas são formuladas. O uso das diferentes categorias ocorre segundo esquemas locais que permitem a avaliação dos contextos pessoal e social de irrupção da doença numa dinâmica que articula as percepções do doente e de seus familiares, as interpretações e diagnósticos de curadores tradicionais e a abordagem dos profissionais da Biomedicina. O estudo mostra que o repertório interpretativo e os meios terapêuticos da Biomedicina são reinterpretados, pelos doentes, segundo a lógica das representações e das práticas locais de saúde, e que o controle da endemia hansênica pressupõe a compreensão das dinâmicas sociais implicadas nas interpretações e práticas da doença, de forma a possibilitar o estabelecimento de uma relação dialógica entre os profissionais de saúde e os atores locais.This study analyzes the social representations of Hansen's disease in São Domingos do Capim-PA, from the perspective of the anthropology of disease.

    Full Text Available Abstract Background The risk of sporadic colorectal cancer is mainly associated with lifestyle factors and may be modulated by several genetic factors of low penetrance. Genetic variants represented by single nucleotide polymorphisms in genes encoding key players in the adenoma carcinoma sequence may contribute to variation in susceptibility to colorectal cancer. In this study, we aimed to evaluate whether the recently identified haplotype encompassing genes of DNA repair and apoptosis, is associated with increased risk of colorectal adenomas and carcinomas. Methods We used a case-control study design (156 carcinomas, 981 adenomas and 399 controls to test the association between polymorphisms in the chromosomal region 19q13.2-3, encompassing the genes ERCC1, ASE-1 and RAI, and risk of colorectal adenomas and carcinomas in a Norwegian cohort. Odds ratio (OR and 95% confidence interval (CI were estimated by binary logistic regression model adjusting for age and gender. Results The ASE-1 polymorphism was associated with an increased risk of adenomas, OR of 1.39 (95% CI 1.06–1.81, which upon stratification was apparent among women only, OR of 1.66 (95% CI 1.15–2.39. The RAI polymorphism showed a trend towards risk reduction for both adenomas (OR of 0.70, 95% CI 0.49–1.01 and carcinomas (OR of 0.49, 95% CI 0.21–1.13 among women, although not significant. Women who were homozygous carriers of the high risk haplotype had an increased risk of colorectal cancer, OR of 2.19 (95% CI 0.95–5.04 compared to all non-carriers although the estimate was not statistically significant. Conclusion We found no evidence that the studied polymorphisms were associated with risk of adenomas or colorectal cancer among men, but we found weak indications that the chromosomal region may influence risk of colorectal cancer and adenoma development in women.

    Although amorphous selenium (a-Se) has a long and successful history of application in optical and X-ray imaging, some of its fundamental properties are still puzzling. In particularly, the mechanism of carrier recombination following x-ray excitation and electric field and temperature dependences of the electron-hole pair creation energy (W_e_h_p) remain unclear. Using the combination of X-ray photocurrent and pulse height spectroscopy measurements, we measure W_e_h_p in a wide range of temperatures (218–320 K) and electric fields (10–100 V/µm) and show that the conventional columnar recombination model which assumes Langevin recombination within a column (a primary electron track) fails to explain experimental results in a wide range of electric fields and temperatures. The reason for the failure of the conventional model is revealed in this work, and the theory of the columnar recombination is modified to include the saturation of the recombination rate at high electric field in order to account for the experimental results in the entire range of fields and temperatures.

    Radioimmunoassay methods have been developed for plasma T, DHT, A and DHEA. Plasma volumes usually employed were: 0,2 ml and 0,5 ml for men and women, respectively for T: 1,0 ml from DHT and 0,5 ml to A and DHEA. After preliminary extraction with diethyl ether, the extracts were applied to Sephadex LH-20 microcolumns to separate T from DHT and to Al 2 O 3 microcolumns purification of DHEA. Following elution, the dried, purified extracts were incubated with specific antisera at temperature 4 0 C overnight, the separation of antibody bound and free fractions being done on activated charcoal-dextrana T-70. The counting was done in liquid scintillations. Specificity studies have shown that the assays for all steroids were specific. The sensitivity was 5 pg for A and DHEA, 6 pg for T and DHT. The interassay coeficient of variation was 5-10% and the interessay precision was 10-15%. The accuracy was satisfactory with a - 8,74% for DHT, 104,82 +- 9,41% for A and 103,66 +- 5,71% for DHEA. The mean +- SD of plasma T, DHT, A and DHEA concentrations in normal men and women determined by these methods were as folows: in men, T:5,2 ng/ml +- 1,3, DHT:0,26 +- 0,18, A:0,9 +- 0,4 and DHEA:4,6 +- 17 and in females: T:0,5 ng/ml +- 0,2, DHT:0,4 +- 0,2, A:0,8 +- 0,5 and DHEA:4,8 +- 1,7. The methodology applied for blood collected simultaneously from peripheral and left and right adrenal vein effluents in basal conditions, after dexamethasone suppression and ACTH stimulation clearly demonstrated direct secretion (presence of a steroid gradient Peripheral/Adrenal vein) of the androgens studied in congenital defficiency of cortical 21-OH'ase.

    Full Text Available A 22 year-old horse developed cholelithiasis with marked atrophy of the right lateral hepatic lobe. The horse had a history of intermittent colic since three years of age, and one of the first episodes of colic was associated with icterus. The size of the right lateral hepatic lobe was extremely reduced. There was a large choledocholith in the common hepatic duct, and several hepatoliths and choleliths in the intra- and extra-hepatic billiary ducts. Microscopically, there was severe atrophy of the right lobe with diffuse proliferation of connective tissue and billiary ducts. The left lateral lobe had peri-portal fibrosis with proliferation of billiary ducts, and billiary stasis. Chemical analysis of the calculi detected amorphous and triple phosphate, bilirubin, calcium, and iron.Um cavalo de 22 anos de idade desenvolveu quadro de colelitíase severa com atrofia do lobo lateral direito.

    We describe the design concept for the highly integrated Pluto payload system (HIPPS): a highly integrated, low-cost, light-weight, low-power instrument payload designed to fly aboard the proposed NASA Pluto flyby spacecraft destined for the Pluto/Charon system. The HIPPS payload is designed to accomplish all of the Pluto flyby prime (IA) science objectives, except radio science, set forth by NASA's Outer Planets Science Working Group (OPSWG) and the Pluto Express Science Definition Team (SDT). HIPPS contains a complement of three instrument components within one common infrastructure; these are: (1) a visible/near UV CCD imaging camera; (2) an infrared spectrograph; and (3) an ultraviolet spectrograph. A detailed description of each instrument is presented along with how they will meet the IA science requirements.

  7. Radioisotope electric propulsion of sciencecraft to the outer Solar System and near-interstellar space

    Radioisotopes have been used successfully for more than 25 years to supply the heat for thermoelectric generators on various deep-space probes. Radioisotope electric propulsion (REP) systems have been proposed as low-thrust ion propulsion units based on radioisotope electric generators and ion thrusters. The perceived liability of radioisotope electric generators for ion propulsion is their high mass. Conventional radioisotope thermoelectric generators have a specific mass of about 200 kg/kW of electric power. Many development efforts have been undertaken with the aim of reducing the specific mass of radioisotope electric systems. Recent performance estimates suggest that specific masses of 50 kg/kW may be achievable with thermophotovoltaic and alkali metal thermal-to-electric conversion generators. Powerplants constructed from these near-term radioisotope electric generators and long-life ion thrusters will likely have specific masses in the range of 100 to 200 kg/kW of thrust power if development continues over the next decade. In earlier studies, it was concluded that flight times within the Solar System are indeed insensitive to reductions in the powerplant specific mass, and that a timely scientific program of robotic planetary rendezvous and near-interstellar space missions is enabled by primary electric propulsion once the powerplant specific mass is in the range of 100 to 200 kg/kW. Flight times can be substantially reduced by using hybrid propulsion schemes that combine chemical propulsion, gravity assist, and electric propulsion. Hybrid schemes are further explored in this article to illustrate how the performance of REP is enhanced for Pluto rendezvous, heliopause orbiter, and gravitational lens missions

In a previous paper, we demonstrated that Mulungu do Morro municipality, in the State of Bahia, has a high seroprevalence to cysticercosis in epileptic patients. OBJECTIVE: to determine the prevalence of taeniasis and positive cysticercosis serology in the population of Mulungu do Morro. METHOD: blood and stool samples were collected from a random sampling of the population, by family. The identification of antibodies against T. solium cysticerci was made by EITB and T. solium antigens were identified using a polyclonal antibody-capture ELISA. RESULTS: the cysticercosis seroprevalence was 1.6% (C.I. = 0.8 to 2.8% and the taeniasis prevalence 4.5% (C.I. = 3.0 to 6.5%. Seropositivity to cysticercosis was higher among those who lived in a house of a person testing positive for coproantigen, p=0.017.

    An analytical method associating accelerated solvent extraction (ASE) and solid-phase micro-extraction (SPME) in immersion mode combined with gas chromatography dual electrons capture detectors (SPME-GC-2ECD) has been developed and studied for the simultaneous determination of 19 organochlorine pesticides (OCPs) and 22 polychlorinated biphenyls (PCBs) in air samples (active and XAD-2 passive samplers). Samples were extracted with ASE with acetonitrile using the following conditions: temperature, 150 °C; pressure, 1500 psi; static, 15 min; cycles, 3; purge, 300 s; flush, 100 %. Extracts were reduced to 1 mL, and 500 μL of this extract, filled with deionised water, was subject to SPME extraction. Experimental results indicated that the proposed method attained the best extraction efficiency under the optimised conditions: extraction of PCB-OCP mixture using 100-μm PDMS fibre at 80 °C for 40 min with no addition of salt. The performance of the proposed ASE-SPME-GC-2ECD methodology with respect to linearity, limit of quantification and detection was evaluated by spiking of XAD-2 resin with target compounds. The regression coefficient (R (2)) of most compounds was found to be high of 0.99. limits of detection (LODs) are between 0.02 and 4.90 ng m(-3), and limits of quantification (LOQs) are between 0.05 and 9.12 ng m(-3) and between 0.2 and 49 ng/sampler and 0.52 and 91 ng/sampler, respectively, for XAD-2 passive samplers. Finally, a developed procedure was applied to determine selected PCBs and OCPs in the atmosphere.

USM is also the first university that has been given the Apex status in Malaysia which is the highest recognition  and trust granted by the Ministry of Higher Education Malaysia to USM. USM has received students from different countries such as China, Libya, Sudan, Egypt, Nigeria, Indonesia, Thailand, Japan, Korea and other countries. However, this research focuses only on the international students from China who were registered as undergraduates in USM. This paper is based on the writer’s experiences in  teaching Bahasa Malaysia III (LKM 300 as a university course that the students must pass as a requirement for international students to graduate. The main dimension of this research is to examine the effectiveness of teaching Malay language as a foreign language to international students (China by using a teaching model that uses the Bahasa Malaysia III (LKM300 course module as determined by the School of Languages, Literacies and Translation. The research method used is full literature where the writers had referred to 43 international student’s final exam scripts that have taken the LKM300 course in the first semester of the 2012/2013 academic session. Their final exam result was taken for full analysis based on the different sections in the exam paper to be used as a source to conclude the research. This research is hoped to be able to provide an explanation of the effective results of the successful usage of the course module and students’ achievement.

    Full Text Available A hanseníase é uma doença que tem altos níveis de incidência no Brasil. De origem bacteriana crônica, com alta infectividade e baixa patogenicidade, tem como hospedeiro primário o homem e como agente etiológico o Mycobacterium leprae. O bacilo de Hansen, como também é conhecido o agente, se acumula principalmente na pele, nos nervos periféricos e pares cranianos, levando a diversas lesões cutâneas, também à perda da condução neural e, consequentemente, a severas alterações anatômicas e funcionais nas extremidades do corpo, como membros e região orofacial. De acordo com estas premissas, foi realizada uma revisão da literatura com intuito de mostrar a fisiopatologia da doença e sua classificação de acordo com as suas manifestações. Desta forma, a literatura, por intermédio de alguns estudos, mostrou que esta doença pode provocar alterações que comprometem significativamente a voz, a audição, os órgãos fonoarticulatórios e as funções estomatognáticas, tornando-se assim, de grande relevância à Fonoaudiologia.Hansen's disease is a malady that has high incidence levels in Brazil. It has a chronic bacterial origin, with high infectivity and low pathogenicity, having the man as its primary host, and the Mycobacterium leprae as its etiological agent. The Hansen's bacillus, as it is known, accumulates mainly in the skin, the peripheral nerves and the cranial nerves pairs, causing many skin lesions, as well as loss of neural conduction and, consequently, severe anatomical and functional changes in the ends of the body, such as members and the orofacial region. Based on these premisses, it was carried out a literature review in order to show the pathophysiology of the disease and its classification according to its manifestations. The literature review showed, through some studies, that the disease might cause alterations that significantly compromise the voice, the hearing, the phonoarticulatory organs, and the

    Full Text Available A terapia expulsiva medicamentosa na litíase ureteral tem ganhado importante espaço na prática clínica, visto que é um método não invasivo e de grande eficácia. Como se trata de uma afecção comum, de alta incidência e custo, a terapia expulsiva possibilita um manejo clínico menos dispendioso e invasivo, quando comparada a procedimentos intervencionistas. Há consenso na literatura que a terapia expulsiva medicamentosa é efetiva e deve ser utilizada em cálculos com cerca de 5 milímetros de diâmetro, visto que as drogas utilizadas aumentam a taxa e diminuem o tempo de expulsão, além de diminuir a dor e o número de internações. O tamanho e localização do cálculo são de extrema relevância para que se possa considerar o manejo conservador. As drogas que obtém as melhores taxas expulsivas são os bloqueadores dos receptores alfa-adrenérgicos e os bloqueadores dos canais de cálcio. Analgésicos também são utilizados para o alívio da dor e o uso de corticoides ainda é questionado. Medicamental expulsive therapy for ureteral stones has gained important place in clinical practice, because it is a noninvasive and highly effective method. As it is a common disorder with high incidence and cost, expulsive therapy provides a less costly and invasive clinical management when compared to interventional procedures. There is a consensus that the medicamental expulsive therapy is effective and should be used in calculations with about 5 millimeters in diameter, since the drugs used increase rate and decrease the time of expulsion, in addition to reducing the pain and the number of hospitalizations. The size and location of the calculi are very important for it to be considered conservative management. The drugs that get the best expulsive rates are alpha - adrenergic receptor blockers and calcium channel blockers. Analgesics are also used for pain relief and the use of corticosteroids is still questioned.

    Purpose: The authors describe the modification to a previously developed Monte Carlo model of semiconductor direct x-ray detector required for studying the effect of burst and recombination algorithms on detector performance. This work provides insight into the effect of different charge generation models for a-Se detectors on Swank noise and recombination fraction. Methods: The proposed burst and recombination models are implemented in the Monte Carlo simulation package, ARTEMIS, developed byFang et al. [“Spatiotemporal Monte Carlo transport methods in x-ray semiconductor detectors: Application to pulse-height spectroscopy in a-Se,” Med. Phys. 39(1), 308–319 (2012)]. The burst model generates a cloud of electron-hole pairs based on electron velocity, energy deposition, and material parameters distributed within a spherical uniform volume (SUV) or on a spherical surface area (SSA). A simple first-hit (FH) and a more detailed but computationally expensive nearest-neighbor (NN) recombination algorithms are also described and compared. Results: Simulated recombination fractions for a single electron-hole pair show good agreement with Onsager model for a wide range of electric field, thermalization distance, and temperature. The recombination fraction and Swank noise exhibit a dependence on the burst model for generation of many electron-hole pairs from a single x ray. The Swank noise decreased for the SSA compared to the SUV model at 4 V/μm, while the recombination fraction decreased for SSA compared to the SUV model at 30 V/μm. The NN and FH recombination results were comparable. Conclusions: Results obtained with the ARTEMIS Monte Carlo transport model incorporating drift and diffusion are validated with the Onsager model for a single electron-hole pair as a function of electric field, thermalization distance, and temperature. For x-ray interactions, the authors demonstrate that the choice of burst model can affect the simulation results for the generation

A amostra constou de 93 membros da rede social, com idade entre 20 e 70 anos, que apoiaram o curso de ação de 83 pacientes diagnosticados no período do estudo. A análise buscou detectar variáveis capazes de discriminar os membros da rede de apoio dos pacientes de hanseníase classificados como casos (presença de incapacidades ou lesões precursoras de incapacidades ou controles. O estudo evidenciou a escassez de informações sobre a transmissão da hanseníase e revelou um quadro transicional onde se confrontam expectativa de cura e uma visão estigmatizante das conseqüências da doença. Apenas uma quarta parte dos sujeitos do estudo suspeitou, antes do diagnóstico, que o paciente era portador de hanseníase, o que sugere baixa percepção do risco representado pela doença e reforça a concepção da invisibilidade das suas manifestações corporais. Os resultados mostram um perfil de percepção e manejo da hanseníase que pode facilitar a propagação da doença e a instalação ou agravamento das suas conseqüências físicas e sociais.This article describes a study done in Recife, Brazil, between November 1993 and July 1994 to explore the opinions of the members of the social network (for example, family members, friends, and neighbors of carriers of Hansen's disease regarding their estimation, interpretation, and management of physical manifestations of the disease in the time leading up to diagnosis.

Em 100% dos soros de indivíduos não infectados residentes em áreas não endêmicas, tanto na ELISA-ovo como na ELISA-adulto os resultados foram negativos. No tocante a reações cruzadas, em 78 soros provenientes de indivíduos portadores de diferentes parasitas intestinais, apenas um apresentou reatividade frente aos antígenos de vermes adultos e ovos. O ELISA-ovo realizado com o soro de 51 indivíduos portadores de ovos de S. mansoni revelou uma alta sensibilidade (98% de casos ovo-positivos; contudo grande número de resultados falso-negativos foi observado em reações como ELISA-adulto, Ouchterlony usando antígeno de verme adulto, reação periovular e intradermoreação. Em casos de jovens portadores de ovos, uma baixa sensibilidade destes testes, exceto para ELISA-ovo, parece ser, em princípio, devido a uma incapacidade de detecção de anticorpos do soro destes pacientes. Parece não existir nenhuma correlação positiva entre os valores dos dois tipos de ELISA (ELISA-ovo e ELISA-adulto dentre os soros isolados de indivíduos com ELISA-positivo. Não obstante, a reação destes soros com antígeno de ovos ou vermes adultos pode ser dividida em dois sub-grupos: em um a reação é mais positiva frente a antígenos de ovos do que frente a antígenos de vermes adultos. Tudo indica que os soros de jovens

    Single nucleotide polymorphisms (SNPs) are the most frequent type of genetic variation in the human genome, and are of interest for the study of susceptibility to and protection from diseases. The haplotype at chromosome 19q13.2-3 encompassing the three SNPs ASE-1 G-21A, RAI IVS1 A4364G and ERCC1 Asn118Asn have been associated with risk of breast cancer and lung cancer. Haplotype carriers are defined as the homozygous carriers of RAI IVS1 A4364G A , ERCC1 Asn118Asn T and ASE-1 G-21A G . We aimed to evaluate whether the three polymorphisms and the haplotype are associated to risk of colorectal cancer, and investigated gene-environment associations between the polymorphisms and the haplotype and smoking status at enrolment, smoking duration, average smoking intensity and alcohol consumption, respectively, in relation to risk of colorectal cancer. Associations between the three individual polymorphisms, the haplotype and risk of colorectal cancer were examined, as well as gene-environment interaction, in a Danish case-cohort study including 405 cases and a comparison group of 810 persons. Incidence rate ratio (IRR) were estimated by the Cox proportional hazards model stratified according to gender, and two-sided 95% confidence intervals (CI) and p-values were calculated based on robust estimates of the variance-covariance matrix and Wald's test of the Cox regression parameter. No consistent associations between the three individual polymorphisms, the haplotype and risk of colorectal cancer were found. No statistically significant interactions between the genotypes and the lifestyle exposures smoking or alcohol consumption were observed. Our results suggest that the ASE-1 G-21A, RAI IVS1 A4364G and ERCC1 Asn118Asn polymorphisms and the previously identified haplotype are not associated with risk of colorectal cancer. We found no evidence of gene-environment interaction between the three polymorphisms and the haplotype and smoking intensity and alcohol consumption

    Full Text Available A tricomoníase é uma protozoose causada pelo Trichomonas vaginalis, que desencadeia uma ampla variedade de manifestações clínicas, podendo estar associada à transmissão do vírus da imunodeficiência humana, câncer cervical, infertilidade, entre outros. No Brasil, a incidência varia entre 20 e 40%. A via primária de transmissão é pelo contato sexual e o diagnóstico laboratorial pode ser realizado através da Reação de Polimerase em Cadeia (PCR, isolamento em meios de cultura e exame do conteúdo vaginal à fresco e/ou corados pelos métodos de Giemsa e Papanicolau. Esse último possui limitações na detecção de patologias consideradas DST, a exemplo da tricomoníase. Esse artigo trata da prevalência de tricomoníase em mulheres usuárias dos laboratórios conveniados ao Ministério da Saúde, na faixa etária de 19 a 44 anos, que foram submetidas ao teste de Papanicolau, em 2004-2005, no Estado de Sergipe. Os resultados revelaram que, em 206.034 usuárias, 7.349 apresentaram tricomoníase, sendo que 3.788 em 2004 e 3.498 em 2005. Observou-se que a prevalência estimada em Sergipe, no biênio estudado, não corrobora com a realidade brasileira, fato esse que pode estar atrelado ao diagnóstico executado.Trichomoniasis is a disease caused by the protozoan Trichomonas vaginalis, which initiates a wide variety of clinical manifestations. It may be associated with human immunodeficiency virus, cervical cancer, infertility and other diseases. Its incidence ranges from 20% up to 40% in Brazil.

    Full Text Available INTRODUÇÃO: O objetivo do presente estudo é apresentar revisão da prevalência e dos principais mecanismos fisiopatológicos que levam a formação da litíase biliar em pacientes submetidos a transplante de órgãos. MÉTODOS: Revisão da literatura abrangendo 29 publicações obtidas das bases Medline/Pubmed, Scielo e Lilacs com cruzamento dos unitermos "transplante, transplante renal, transplante hepático, cálculo biliar, colecistite.". Vários estudos que utilizaram a ultrassonografia demonstraram aumento na prevalência da litíase biliar em pacientes submetidos a transplante de órgãos. A taxa de formação de cálculos novos após o transplante variou de 10 a 55% e a total (cálculos formados antes e após o transplante de 17 a 68%. Tanto o ganho como a perda de peso rápida, que podem ocorrer após o transplante, predispõem à formação de cálculos biliares. O uso do imunossupressor ciclosporina é considerado como o principal fator que aumenta a incidência de litíase biliar após o transplante. CONCLUSÃO: A prevalência de litíase biliar é maior nos pacientes submetidos a transplante de órgãos do que na população geral. As principais alterações que ocorrem no paciente transplantado que predispõem a formação dos cálculos são as alterações do peso corporal, uso de imunossupressores, diabete melito e hiperlipidemia.INTRODUCTION: The objective of the present study is to review the prevalence and the main physiopathologic mechanisms that result in gallstone formation in transplant patients.

MÉTODOS: foram incluídas 99 pacientes com suspeita clínica de candidiase vulvovaginal, procedentes de Natal, RN, atendidas entre maio de 2003 e maio de 2005, perfazendo-se o total de 294 coletas. O material clínico, colhido por zaragatoas, foi semeado em CHROMagar Candida®. As leveduras foram identificadas pelo método clássico, além da prova de crescimento a 42 e 45ºC e da prova do caldo Sabouraud hipertônico. A sintomatologia, fatores de risco e colonização anal foram analisados de acordo com a positividade ou negatividade para Candida spp. As culturas positivas para C. albicans nos dois sítios foram comparadas com outros resultados encontrados. Para análise estatística utilizou-se o teste do chi2, com correção de Yates e o teste exato de Fisher. RESULTADOS: a espécie mais frequente foi C. albicans em 69% dos casos. Uso de roupas íntimas justas e/ou sintéticas, presença de doenças alérgicas, ocorrência de prurido, leucorréia e hiperemia apresentaram associação com a positividade vaginal para Candida spp. A chance de uma paciente com colonização anal positiva de apresentar positividade vaginal concomitante foi 2,8 e 4,9 vezes maior, respectivamente, para Candida spp e C. albicans. A chance de uma paciente com cultura anal positiva para C. albicans de apresentar resultado vaginal positivo foi 3,7 vezes maior quando comparada a espécies não C. albicans. CONCLUSÕES: C. albicans foi a espécie mais comum, tendo sido observada associação da positividade vaginal para Candida spp com uso de roupas justas e/ou sintéticas, doenças alérgicas, prurido, leucorréia e eritema (pPURPOSE: to analyze patients with vulvovaginal candidiasis with respect to risk factors, symptomatology

    Full Text Available Os programas de controle da hanseníase se beneficiariam de um método fácil para estimar prevalência e avaliar o impacto das ações de controle na prevalência da doença. A determinação da soroprevalência de anticorpos contra PGL-I através de estudos com crianças em idade escolar foi sugerida como indicador útil da taxa de prevalência da hanseníase a nível municipal.Para investigar se a soropositividade estaria associada aos coeficientes de detecção da hanseníase e se poderia ser usada como indicador da prevalência em outras áreas, 7.073 crianças em três estados endêmicos de hanseníase no Brasil foram testadas. Resultados mostram uma considerável variação da distribuição de soropositividade nas comunidades, independente do número de casos de hanseníase detectados. A soroprevalência foi significativamente menor nos colégios. Nenhuma diferença na distribuição da soropositividade determinada por ELISA ou dipstick foi observada. Nenhuma correlação entre o coeficiente de detecção da hanseníase e soropositividade pôde ser estabelecida.Leprosy control programs would benefit expressively from an easy method to estimate disease prevalence and to assess the effect of leprosy control measures on disease prevalence. Determination of the seroprevalence of antibodies to PGL-I through school children surveys might be a useful indicator of leprosy prevalence at the district level. To investigate whether seropositivity rates could be related to leprosy detection rates and whether seropositivity could be used as a proximal indicator to predict the leprosy incidence in other areas, 7,073 school children in three different leprosy-endemic states in Brazil were tested. The results show a widely varying distribution of seropositivity in the communities independent of the number of leprosy cases detected. Seroprevalence was significantly lower at private schools. No differences in the patterns of seropositivity between ELISA

    colecistomicrolitíase (cálculos com até 3 mm. Não há, no momento, consenso quanto ao melhor método propedêutico para diagnosticá-lo e, entre os propostos, nenhum apresenta alta sensibilidade. A ecoendoscopia (EE é excelente no diagnóstico da pancreatite crônica incipiente e microcálculos da vesícula biliar (MCV ou colédoco. São poucas as referências na literatura internacional e nenhuma na nacional a respeito do emprego da EE na PA. O objetivo deste trabalho é o de estabelecer o valor da EE no diagnóstico da colecistomicrolitíase em doentes com PA sem causa aparente. MÉTODOS: Trinta e seis pacientes com o diagnóstico de PA sem causa aparente foram consecutivamente estudados durante cinco anos. Dos enviados para exame ecoendoscópico, 21 mulheres e 15 homens com média de idade de 41,6 anos. Todos haviam sido submetidos antes a pelo menos um US e uma TC, que não revelaram alterações na via bílio-pancreática e 63,9% deles tinham apresentado mais de um episódio de PA. O diagnóstico da colecistomicrolitíase pela EE realizada até uma semana durante o surto de PA baseou-se no tamanho do cálculo (até 3 mm, inclusive e hiperecogeneicidade com ou sem sombra acústica. Todos os doentes foram colecistectomizados, após o exame ecoendoscópico. RESULTADO: O exame das peças cirúrgicas mostrou que 27 (75% doentes apresentavam MCV e nove (25% não. A EE levou a erro no diagnóstico da microlitíase em seis (16,8% casos, quatro casos de falsos-positivos e dois casos de falsos-negativos. Em 30 casos (83,2% houve confirmação dos seus resultados. A sensibilidade, a especificidade, os valores preditivos positivo, negativo e a acurácia (com intervalo de confiança de 95% para a EE no diagnóstico dos MCV foram: 92,6% (74,2 a 98,7%, 55,6% (22,7 a 84,7%, 86,2% (67,4% a 95,5%, 71,4% (30,3 a 94,9% e 83,2% (66,5% a 93% respectivamente.

    Full Text Available INTRODUÇÃO: a anseníase multibacilar pode causar comprometimento da mucosa oral, com ou sem lesões aparentes. Há poucos estudos que tratam deste assunto na era da multidrogaterapia. OBJETIVO: Verificar a freqüência do comprometimento da mucosa oral em pacientes de hanseníase multibacilar. CASUÍSTICA E MÉTODOS: Foi realizado um estudo transversal em vinte pacientes de hanseníase multibacilar, não-tratados, atendidos consecutivamente em Dracena, São Paulo, entre o período de 2000 e 2002. Foi realizado exame clínico completo da mucosa oral. Os pacientes foram submetidos a biópsias na mucosa jugal, na língua e no palato mole, em alteração ou em pontos pré-estabelecidos. Os cortes foram corados pelas técnicas da hematoxilina-eosina e Ziehl-Neelsen. O encontro de granuloma e bacilos álcool-ácido-resistentes ao exame histopatológico determinou o comprometimento específico. RESULTADOS: O estudo envolveu 19 pacientes multibacilares com tempo médio de evolução de 2,5 anos. Ocorreu comprometimento histopatológico específico em apenas um paciente virchowiano, com mucosa oral clinicamente normal, na língua e no palato mole. CONCLUSÕES: 1. Alteração clínica na mucosa oral não implica em comprometimento pela doença, é necessário confirmação histopatológica. 2. Alterações clínicas específicas aparentes são raras. 3. A mucosa oral clinicamente normal pode exibir comprometimento histopatológico específico.INTRODUCTION: Multibacillary leprosy may involve the oral mucosa, with or without apparent lesions.

Trabalha-se o conceito de risco coletivo pela definição de micro-áreas homogêneas mediante o indicador de carência social, verificando-se sua coerência com padrões da distribuição da hanseníase obtidos da base de dados do SINAN para o Município de Olinda no período 1991-96. Para cada estrato, definido segundo níveis semelhantes dos indicadores, foi calculado o coeficiente de detecção médio para o período. Ao exame da associação entre carência social (risco e coeficiente de detecção de hanseníase obteve-se coeficiente de explicação de 66,1% no modelo multiplicativo, acrescido para 84,3% com a variável renda. Para atender à lógica de intervenção, definiram-se estratos de alto, médio e baixo risco nos distritos sanitários e área programática. A construção desses mapas mostrou-se útil a instrumentalizar o planejamento em nível local.In the State of Pernambuco, Brazil, leprosy has been mainly an urban disease, with an uneven geographical distribution related at least partially to the way urban space has been occupied and transformed. Spatial analysis may thus become an important tool to establish an epidemiological surveillance system for leprosy. Homogeneous micro-areas were defined in the city of Olinda through the integration of two databases, the Population Census and SINAN, and through the use of digital maps and geoprocessing techniques. Census tracts were classified according to a social deprivation index (SDI, and micro-area homogeneity was based on similar values for this indicator.

Doze pacientes com essas seqüelas participaram da pesquisa, separados aleatoriamente em dois grupos: o grupo FNP, tratado com facilitação neuromuscular proprioceptiva, e o grupo AEP, com alongamento estático passivo. Ambos realizaram dez sessões de alongamentos, sendo submetidos à avaliação inicial e final nas quais foram aplicados o questionário SF-36, mensuradas a amplitude de movimento (ADM do punho e tornozelo, testados os reflexos e a sensibilidade. No grupo FNP foi observada melhora na ADM do tornozelo e em três domínios do SF-36; no grupo AEP, em cinco domínios do SF-36. Quando comparados os grupos, o FNP obteve melhora significativa na extensão do punho, dorsiflexão e plantiflexão em relação ao AEP. A facilitação neuromuscular proprioceptiva parece ser um método mais eficaz para ganhar alongamento muscular e ADM de tornozelo e punho em pacientes com seqüelas de hanseníase.

    The school experience for queer youth is often quite different from that of their heterosexual and gender-conforming peers; yet it is often the c ase that little attention is given to the disparate and inequitable educational and social conditions under which lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) youth must learn. In fact, the entirety of pedagogical structures in many schools creates milieus where queer youth, those who have loved ones who are queer, and those who are merely perceived to be queer are systematically marginalized and deprived of their right to a safe, supportive, and equitable educational experience. Transformative leadership theory (TLT) inspires educational leaders to create inclusive and excellent schools for all youth. Neither a prescriptive model nor a process-oriented theory, TLT offers eight tenets that operate in concert to form an authentic way of being informing and guiding leaders' decisions and actions toward the goal of individual, organizational, and societal change.

However, many doubts regarding the safety and high risk of infectious diseases in these patients remain. The main objective of this report was to present a case of lepromatous leprosy in a rheumatoid arthritis patient using TNF blockers. The development of adverse events should be rigorously observed, especially those related to infectious agents. Thus, appropriate investigation of skin lesions in patients receiving anti-TNFa therapy is recommended, as the initial clinical manifestation may be unusual, particularly in endemic regions in Brazil.

    Full Text Available BACKGROUND: assessment instruments of nail psoriasis have been published in literature as means to standardize the previous subjective assessments of authors. OBJECTIVES: Using Nail Psoriasis Severity Index for evaluation in patients with plaque psoriasis during treatment with acitretin. METHODS: Thirty volunteers with plaque psoriasis were selected for the study. Twenty patients (8 women and 12 men completed the study. The initial dose of acitretin was 0.3 mg/kg/day for 30 days and was later raised to 0.5 mg/kg/day. Nail Psoriasis Severity Index was collected in the first evaluation, after 2 and 4 months. Nails of both hands were evaluated. RESULTS: nail lesions were present in all patients at first evaluation. The initial Nail Psoriasis Severity Index median was 20 and the final score 20.5 (2.5% of worsening at the end of the study. No statistically significant difference between the three evaluations was found (X2 = 0.8084, GL = 2, p = 0.6657. Seven patients worsened in the final score. Three patients improved 50% of the initial Nail Psoriasis Severity Index and only one had an improvement of 75%. Linear correlation showed a weak association between the improvement percentage in PASI and Nail Psoriasis Severity Index (r = 0.105, F = 2.12, p = 0.162. CONCLUSION: The method was easy and of rapid execution while potentially bringing information about changes in nail plate and matrix during treatment. The Nail Psoriasis Severity Index does not quantify the existing lesions and might not have the sensitivity to detect small changes.FUNDAMENTOS: instrumentos de avaliação da psoríase ungueal têm sido publicados na literatura como meio de padronizar as avaliações antigamente subjetivas dos autores.

    Full Text Available Toxocariasis is caused by infection of man by Toxocara canis and Toxocara cati larvae, the common roundworm of dogs and cats. Because larvae are difficult to detect in tissues, diagnosis is mostly based on serology. Non specific reactions are observed mainly due to cross-reactivity with Ascaris sp antigens. This investigation aimed at developing and evaluating an indirect antibody competition ELISA (IACE employing a specific rabbit IgG anti-Toxocara canis excretory-secretory antigens as the competition antibody, in order to improve indirect ELISA specificity performed for toxocariasis diagnosis. For that, the rabbit IgG was previously absorbed by Ascaris suum adult antigens. Sensitivity and specificity of IACE were first evaluated in 28 serum samples of mice experimentally infected with T. canis embryonated eggs. Adopting cut-off value established in this population before infection, sensitivity and specificity were 100% after 20 days post-inoculation. For human population IACE was evaluated using sera from 440 patients with clinical signs of toxocariasis and the cut-off value was established with 60 serum samples from apparently healthy individuals. Using as reference test the indirect ELISA performed by Adolfo Lutz Institute, sensitivity was 60.2%, specificity was 98% and concordance was 77.3%. Repeatability of IACE was evaluated by the inter-reactions variation coefficient (2.4%.A toxocaríase, uma emergente zoonose, é uma síndrome clínica decorrente da infecção humana por larvas de Toxocara canis e Toxocara cati, parasitas intestinais de cães e gatos, respectivamente. A dificuldade de detecção das larvas nos tecidos e a inespecificidade dos sinais clínicos tornam os testes sorológicos os meios diagnósticos mais adequados. Os antígenos excretores-secretores de T. canis empregados nos testes sorológicos, embora tenham contribuído para melhorar a especificidade destes, apresentam reações cruzadas com diversos parasitas

Este trabalho teve por objetivo relatar aspectos epidemiológicos de um foco de tungíase ocorrido em um SISCAL. Foram examinados clinicamente 72 animais, sendo 6 cachaços, 9 fêmeas lactantes, 13 em gestação e 6 em cobrição, 20 leitões lactantes e 34 leitões desmamados e transferidos para unidades de terminação. Verificou-se que nenhum dos cachaços estava infestado (granja 1= 48 e que em 50% do total de fêmeas examinadas ocorreram lesões com maior freqüência nos tetos, o que nas porcas lactantes deu origem à agalaxia por obstrução do canal galactóforo ocasionando involução da glândula mamária. Em 90% dos leitões lactantes constatou-se dificuldade de locomoção causada pela presença do parasito na região plantar do casco e 25% apresentavam, além disto, lesões no jarrete.

    Full Text Available A hanseníase é uma doença infectocontagiosa espectral que acompanha-se por uma série de eventos imunológicos desencadeados pela resposta do hospedeiro frente ao agente etiológico, o Mycobacterium leprae. Evidências sugerem que a indução e manutenção da resposta imune/inflamatória na hanseníase estão vinculadas a interações de múltiplas células e fatores solúveis, particularmente através da ação de citocinas. Nesse estudo, foram mensurados níveis de IL-1β e IL-1Ra de 37 casos novos de hanseníase acompanhados ao longo do tratamento e 30 controles sadios pelo teste ELISA. A coleta de sangue periférico foi realizada em quatro tempos para os casos de hanseníase (pré-tratamento com PQT, 2ª dose, 6ª dose e pós-PQT e em único momento para os controles. Na comparação dos níveis das moléculas de casos no pré-PQT e controles, houve diferença estatisticamente significativa somente para IL-1β. Nossos resultados sugerem a participação dessa citocina no processo imune/inflamatório.Leprosy is an infectious and contagious spectral disease accompanied by a series of immunological events triggered by the host's response to the etiologic agent, Mycobacterium leprae. Evidence suggests that the induction and maintenance of the immune/inflammatory response in leprosy are linked to multiple cell interactions and soluble factors, mainly through the action of cytokines. The ELISA test was used to measure the levels of IL-1β and IL-1Ra in 37 new leprosy patients followed-up during treatment and 30 healthy controls. Peripheral blood was collected four times during the treatment of leprosy patients (MDT pretreatment, 2nd dose, 6th dose and post-MDT, and only once from the controls. The comparison of molecular levels in pre-MDT patients and controls showed a statistically significant difference for IL-1β. The results suggest the participation of this cytokine in the genesis of the immune/inflammatory process.

O berne, Dermatobia hominis não tem sido erradicado de nenhum pais, devido a que não dispomos de técnicas para sua criação massal em dietas artificiais. Estão faltando também estudos sobre a dispersão, comportamento sexual e sítios de agregação dos adultos no campo. Devido a que as miíases continuarão sendo controladas basicamente com inseticidas, recomendações para manejar a resistência aos inseticidas e estudos sobre métodos alternativos são discutidos visando um Manejo Integrado do berne e da bicheira com fundamentos ecológicos.The eradication of the screwworm, Cochliomyia hominivorax, from USA, Central America and the North of Africa has been achieved by rearing and releasing sterile males. Why we do not decide to eradicate this insect from the southamerican countries too? In this paper the scientific, ecological and economic reasons before taking such a courageous decision are discussed. The human botfly, Dermatobia hominis, has not been eradicated from any country, because there is so far no technique available for mass production in artificial diets. Studies on dispersion, sexual behavior and aggregation sites of the adults in the field are also not known. Why the neotropical myiases will continue to be treated basically with chemicals, recommendations for insecticide resistance management and studies on alternative methods are discussed trying to apply in the future an ecologically based pest management of the screwworm and the human botfly.

As lesões ósseas mais comuns são devidas ao trauma e a infecção secundária nos tecidos denervados. Radiograficamente, são observados vários graus de reabsorção das extremidades distais envolvendo mãos e pés, ocasionando perda dos dígitos e osteoartropatia neuropática de pequenas articulações. Os achados radiológicos são semelhantes às outras condições nas quais há déficit sensorial, como esclerodermia, siringomielia e diabetes mellitus. A ultra-sonografia (US e a ressonância magnética (RM podem ser úteis na avaliação do comprometimento dos nervos periféricos auxiliando no diagnóstico das neurites, abscessos e no diagnóstico diferencial das síndromes compressivas.In leprosy, bone lesions due direct invasion of bacilli are low in incidence and these lesions exhibit radiologic findings of acute and chronic osteomyelitis similar to those of other granulomatous infectious agents. The more common bone lesions are those due to injurious effects of trauma and infection imposed upon denervated tissues. Radiographycally are seen various degrees of reabsorption of the extremities involving hands and feet with the loss of digits and disorganizing arthropathies in small joints. The radiologic appearance are similar to other conditions in which there is sensory impairment like scleroderma, syringomielia and diabetes mellitus. The ultrasonography and magnetic resonance imaging (MRI can be helpful in evaluation of the involvement of the peripheral nerves helping in the diagnosis of the neuritis, abscess and differential diagnosis in compressive syndromes.

    Full Text Available A hanseníase é uma doença infecciosa de evolução crônica causada pelo Mycobacterium leprae que acomete com maior frequência a mucosa nasal. Esse acometimento independe da forma clínica da doença e pode ocorrer mesmo antes do aparecimento de lesões na pele ou em outras partes do corpo. Faz-se necessário a vigilância epidemiológica dos contatos de casos novos de hanseníase para o diagnóstico precoce da doença. OBJETIVOS: Identificar lesões específicas e precoces de hanseníase por meio de exame endoscópico, baciloscópico, histopatológico e da reação em cadeia da polimerase em Tempo Real da mucosa das cavidades nasais dos contatos domiciliares e peridomiciliares com sorologia positiva para o antígeno glicolipídio fenólico. MATERIAL E MÉTODOS: Estudo prospectivo transversal em 31 contatos de pacientes de hanseníase com sorologia positiva (PGL-1, 05 controles negativos e 01 positivo no período de 2003 a 2006. RESULTADOS: Entre os contatos soropositivos a PCR-RT foi positiva para a presença de DNA de M. leprae em 06 (19,35% destes e o maior número de cópias do genoma do bacilo foi encontrado no contato que adoeceu. CONCLUSÃO: Isoladamente os exames da mucosa nasal não permitiram o diagnóstico precoce da hanseníase, mas com a combinação de vários métodos, o exame dos contatos pôde ajudar na identificação da infecção subclínica e monitoramento daqueles que poderiam ter papel importante na transmissão da doença.Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The disease more frequently affects the nasal mucosa and can occur independently of its clinical form or even before lesions on the skin or on other parts of the body. It is necessary to employ epidemiological surveillance of household contacts with new leprosy cases for early disease diagnosis. AIM: identify specific and early leprosy lesions through endoscopic, baciloscopy, histopathology exams, and real time polymerase chain

    Full Text Available FUNDAMENTOS: A psoríase leva a um impacto negativo significativo na qualidade de vida e está associada a comorbidades. A atividade inflamatória das placas psoríacas se inicia, em parte, pela ativação de linfócitos Th1, que liberam citocinas pró-inflamatórias, como TNF alfa. Infliximabe neutraliza a atividade biológica do TNF alfa. Reações adversas que ocorrem durante a infusão e até 24 horas após são chamadas de agudas. Reações tardias ocorrem entre 24 horas e 14 dias após infusão. OBJETIVO: Avaliar o perfil dos pacientes com psoríase moderada a grave e resistente ao tratamento convencional, bem como as reações adversas ao infliximabe. MÉTODO: Foram tratados com infliximabe 53 pacientes: 40 homens e 13 mulheres. A dose utilizada foi 5 mg/kg nas semanas 0, 2 e 6 (fase de indução, seguida da fase de manutenção a cada oito semanas. RESULTADO: Dentre os 53 pacientes, seis se submeteram apenas à fase de indução, obtiveram Pasi 90-100 e não receberam mais a droga. Quarenta e sete pacientes continuaram recebendo a medicação por pelo menos dois, três anos. Deles, 55,3% (26 apresentaram algum efeito adverso. Os efeitos adversos precoces foram observados em 34% dos pacientes, e os tardios, em 36,1% dos pacientes. Foi encontrada uma prevalência de 57,4% de comorbidades nesses pacientes. CONCLUSÃO: O infliximabe mostrou-se seguro e eficaz no presente estudo. Dentre as comorbidades associadas aos pacientes neste estudo, a obesidade se relacionou com uma resposta mais tardia e menos eficiente. Efeitos adversos precoces e tardios, quando bem monitorados, não impedem a manutenção da terapêutica e não expõem os pacientes a riscos não controlados.BACKGROUND: Psoriasis exerts a significant negative effect on quality of life and is associated with comorbidities.

    Full Text Available Genetic engineering has made possible the creation of Genetic Modified Organisms (GMOs, or transgenic crops. The growth around the world of transgenic crops areas for commercial purposes, such as soybean, maize, canola and cotton is being amazing: from 1.7 million hectares in 1996 to 52.6 million in 2001. Historically, not many technologies have reached, in such a short period of time, such a higher adoption. The use of these technologies, nevertheless their well-known benefits, has brought some worries related with biosafety. In Colombia the Colombian Institute for Agriculture and Cattle (ICA, its Spanish acronym in order to introduce GMOs to the country and prevent or minimize the potential risk for agriculture generated by this kind of organisms, has established two instruments: the Agreement 013/98, creating the National Technical Biosafety Committee (CTN, its Spanish acronym, intersectorial adviser organism; and the Resolution 3492/98, establishing procedures for introduction, production, reléase and marketing of GMOs for agricultural purposes. Under this regulations, ICA has approved five different requests involving eight events with GMOs: carnation for commercial multiplicación purposes; cotton and rice for evaluation genotype in field at a small scale; cassava, brachiaria, stylozantes, coffee and sugar cane for research in genetic improvement throughout genetic engineering techniques in confined handling. Based on the accomplished experience, the future will make improve the legal and institutional instruments, as well as technical and scientific capacity of the country in biosafety.

Foram analisados 38 materiais produzidos entre 1993 a 2005, por instituições governamentais e não-governamentais e realizados dois grupos focais com profissionais atuantes no PCH. Durante os grupos focais 6 materiais foram examinados. Os resultados revelaram a verticalidade e fragmentação nos processos comunicativos, expressas pela: ênfase em campanhas, produção centralizada, homogeneização dos públicos e conteúdos e privilégio dado ao saber biomédico. As atividades horizontais e participativas não eram comuns. Foi identificada uma lacuna entre a institucionalização do discurso da hanseníase, como alternativa à terminologia da lepra, e a sua circulação e consumo entre os diferentes atores sociais.This article reflects on the communications processes in the Hansen Disease Control Programs under the Unified National Health System (SUS in Brazil, analyzing how professionals at two public health services in Rio de Janeiro perceive the educational materials on the disease.

    Full Text Available A teníase é uma doença que se manifesta no ser humano em decorrência da presença da forma adulta da Taenia sp., enquanto a cisticercose decorre da infecção pelo estágio larvar da Taenia sp. ou Taenia solium, no caso dos suínos e humanos. Foi realizado um estudo transversal visando a determinar a prevalência de cisticercose em suínos e de teníase em 176 propriedades localizadas na zona rural de Viçosa, Minas Gerais (MG. Foram coletadas amostras de sangue de 226 suínos e fezes de 266 humanos, além da realização de um inquérito epidemiológico. Não foi identificada teníase humana, e a prevalência da cisticercose suína foi de 0,4%. As informações obtidas mostraram que a maioria das pessoas possuía o hábito de consumir carne suína não inspecionada; entretanto, todas as pessoas se alimentavam da carne bem aquecida. Em apenas 1,1% das propriedades, o esgoto era depositado diretamente no solo e em 99,4% destas a água era canalizada, enquanto 88,1% dos suínos eram criados presos. Concluiu-se que, na zona rural do município de Viçosa-MG, a prevalência do complexo teníase-cisticercose foi baixa, mostrando ainda um nível de contaminação inferior ao de outros municípios onde o complexo foi estudado.Taeniasis occurs due to the presence of the adult form of Taenia sp. in human beings, and cysticercosis is caused by the presence of the larval stage of T. solium in pigs and humans. A transversal study was conducted aiming to determine the prevalence of porcine cysticercosis and Taeniasis in 176 farms located in rural areas of Viçosa-MG. Blood samples of 226 pigs, and feces samples of 266 humans were collected. An epidemiological survey has also been done. We found a prevalence of 0.4% of porcine cysticercosis and Taeniasis has not been found.

    The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion

  6. Experiment Databases

    Vanschoren, Joaquin; Blockeel, Hendrik

    Next to running machine learning algorithms based on inductive queries, much can be learned by immediately querying the combined results of many prior studies. Indeed, all around the globe, thousands of machine learning experiments are being executed on a daily basis, generating a constant stream of empirical information on machine learning techniques. While the information contained in these experiments might have many uses beyond their original intent, results are typically described very concisely in papers and discarded afterwards. If we properly store and organize these results in central databases, they can be immediately reused for further analysis, thus boosting future research. In this chapter, we propose the use of experiment databases: databases designed to collect all the necessary details of these experiments, and to intelligently organize them in online repositories to enable fast and thorough analysis of a myriad of collected results. They constitute an additional, queriable source of empirical meta-data based on principled descriptions of algorithm executions, without reimplementing the algorithms in an inductive database. As such, they engender a very dynamic, collaborative approach to experimentation, in which experiments can be freely shared, linked together, and immediately reused by researchers all over the world. They can be set up for personal use, to share results within a lab or to create open, community-wide repositories. Here, we provide a high-level overview of their design, and use an existing experiment database to answer various interesting research questions about machine learning algorithms and to verify a number of recent studies.

    Full Text Available BACKGROUND: Psoriatic arthritis is an inflammatory arthritis associated with psoriasis. Its prevalence in patients with psoriasis varies from 7 to 42% but its exact prevalence is unknown. OBJECTIVES: Considering the lack of national data related to its diagnosis in patients with psoriasis, this study aims to describe the clinical, laboratorial and radiological manifestations of psoriatic arthritis in these patients. METHODS: We evaluated 133 patients with psoriasis, treated as outpatients. These patients were asked to fill in the forms with data about the disease and were submitted to a clinical evaluation by a dermatologist and a rheumatologist. Suspected cases of arthritis were referred for further investigation and were classified according to presence or absence of psoriatic arthritis according to CASPAR criteria. RESULTS: The number of patients with psoriatic arthritis was 47 (35%, 17 of them were new cases. There was no difference between the groups regarding the type of psoriasis, nail involvement, presence of scalp lesions and psoriatic arthritis. Patients with psoriatic arthritis had more enthesitis and dactylitis (46.7% than those without arthritis. CONCLUSIONS: Despite the high prevalence of arthritis found, we know that results from epidemiological studies are variable, which limits their use and interpretation. We conclude that more studies are needed to draw a profile of rheumatic manifestations in our population of psoriasis patients.FUNDAMENTOS: A artrite psoriásica é uma artrite inflamatória associada à psoríase.

    Full Text Available O estudo teve como objetivo avaliar os casos de urolitíase canina em que a composição mineral dos urólitos foi analisada quantitativamente. Foi avaliada quantitativamente a composição mineral de 156 urólitos obtidos de cães (nefrólitos, ureterólitos, urocistólitos e uretrólitos. Desse total, 79,5% (n=124 eram simples, 18% (n=28 eram compostos e apenas 2,5% (n=4 eram mistos. A estruvita foi o tipo mineral mais frequente nos urólitos simples (47,6%; n=59, em todos os mistos (100%; n=4 e nas camadas núcleo e pedra de urólitos compostos (32,1 e 75%, respectivamente. O oxalato de cálcio foi o segundo mineral mais frequente dos urólitos simples (37,9%, n=47. Ao contrário do que é preconizado para os urólitos simples, as recomendações para o tratamento de urólitos compostos são mais complexas, tais como protocolos de tratamento de dissolução diferentes (se composto por minerais distintos e passíveis de dissolução como urato e estruvita. Além disso, a dissolução pode não ser viável, caso ocorra presença de material insolúvel envolvendo o urólito ou se este representar mais de 20% da camada. Vinte e dois urólitos compostos (78,7% apresentaram uma camada externa não passível de dissolução (oxalato de cálcio ou fosfato de cálcio; dois (7,1% apresentaram camadas externas passíveis de dissolução (estruvita ou urato, porém camadas mais internas não solúveis, o que permitiria apenas a dissolução parcial do urólito. Assim, o conhecimento da composição de todas as camadas que compõem o urólito é essencial para o entendimento da formação do cálculo e consequentemente para a indicação do tratamento adequado, assim como para prevenção de recidivas.The aim of this study was to evaluate dogs with urolithiasis in which mineral composition of calculi was quantitatively analyzed.

    My name is Nicoara Floarea and I am teacher at Secondary School Calatele and I teach students from preparatory class and the second grade . They are six-eight years old. In my activity, for introducing scientific concepts to my students, I use various and active methods or traditional methods including experiments. The experiment stimulates students' curiosity, their creativity, the understanding and knowledge taught accessibility. I propose you two such experiments: The life cycle of the plants (long-term experiment, with rigorous observation time):We use beans, wheat or other; They are grown in pots and on the cotton soaked with water,keeping under students' observation protecting them ( just soak them regularly) and we waiting the plants rise. For discussions and comments of plant embryo development we use the plants which rose on the cotton soaked with water plants at the end of the first week. Last school year we had in the pot climbing beans which in May made pods. They were not too great but our experiment was a success. The students could deduce that there will develop those big beans which after drying will be planted again. The influence of light on plants (average duration experiment with the necessary observation time): We use two pots in which plants are of the same type (two geraniums), one of them is situated so as to get direct sunlight and other plant we put in a closed box. Although we wet both plants after a week we see that the plant that benefited from sunlight has turned strain in direct sunlight, developing normally in return the plant out of the box I have yellowed leaves, photosynthesis does not She has occurred . Students will understand the vital role of the Sun in plants' life, both in the classroom and in nature. The experiment is a method of teaching students extremely pleasant, with a remarkable percentage of acquiring more knowledge.

    Channeling of water flow and tracer transport in real fractures in a granite body at Stripa have been investigated experimentally. The experimental site was located 360 m below the ground level. Two kinds of experiments were performed. In the single hole experiments, 20 cm diameter holes were drilled about 2.5 m into the rock in the plane of the fracture. Specially designed packers were used to inject water into the fracture in 5 cm intervals all along the fracture trace in the hole. The variation of the injection flowrates along the fracture were used to determine the transmissivity variations in the fracture plane. Detailed photographs were taken from inside the hole and the visual fracture aperture was compared with the injection flowrates in the same locations. Geostatistical methods were used to evaluate the results. Five holes were measured in great detail. In addition 7 holes were drilled and scanned by simpler packer systems. A double hole experiment was performed where two parallel holes were drilled in the same fracture plane at nearly 2 m distance. Pressure pulse tests were made between the holes in both directions. Tracers were injected in 5 locations in one hole and monitored for in many locations in the other hole. The single hole experiment and the double hole experiment show that most of the fracture planes are tight but that there are open sections which form connected channels over distances of at least 2 meters. It was also found in the double hole experiment that the investigated fracture was intersected by at least one fracture between the two holes which diverted a large amount of the injected tracers to several distant locations at the tunnel wall.

It attempts to elaborate the process through which a poet is uplifted in a creative moment beyond terrestrial boundaries and is aligned with the ‘state of Perfection'. The role of successive generations of audiences in rediscovering the meaning of a poetic image is defined as life principle of all great poetry. Shakespeare is discussed as the ultimate example of this principle since his popularity remains an irreversible phenomenon

    Intragenic transcripts initiate within the coding region of a gene, thereby producing shorter mRNAs and proteins. Although intragenic transcripts are widely expressed [1], their role in the functional regulation of genes remains largely unknown. In budding yeast, DNA replication stress activates the S-phase checkpoint that stabilizes replication forks and arrests cells in S-phase with a short spindle [2-4]. When yeast cells were treated with hydroxyurea (HU) to block DNA synthesis and induce ...

    Full Text Available BACKGROUND: Nail psoriasis may affect up to 90% of patients with psoriasis in the course of the disease throughout their lives and it is often a therapeutic challenge to dermatologists. Topical treatments described in the literature have demonstrated variable efficacy, and unsatisfactory results have been associated to inefficient penetration of the active ingredient into the nail plate and proximal nail fold. Recently the use of clobetasol on nail lacquer vehicle has been suggested, with satisfactory results and no side effects. OBJECTIVE: To determine the efficacy and safety of clobetasol in nail lacquer vehicle in three concentrations (0.05%, 1% and 8% in patients with nail psoriasis. METHODS: Prospective, controlled, randomized pilot study in fifteen patients with nail bed and/or nail matrix psoriasis in both hands, subdivided into three groups: A(0.05% clobetasol nail lacquer, B(1% clobetasol nail lacquer and C(8% clobetasol nail lacquer. All groups used clobetasol nail lacquer on the left hand and base coat nail lacquer as control on the right, twice a week for 16 weeks. Clinical evaluation was done by photographic records and the NAPSI score of both treated and control hands, as well as modified NAPSI score of the most affected nail of the treated hand. RESULTS: Group C showed a statistically relevant clinical response compared to the other groups, reflected in the improvement of clinical parameters, of treated hand NAPSI score, when compared to the control hand, and modified NAPSI score of the most affected nail in the treated hand. CONCLUSION: The 8% clobetasol nail lacquer was effective and safe, and it can be considered a good option of topical therapy in the treatment of nail psoriasis.FUNDAMENTOS: A psoríase ungueal, de difícil manejo terapêutico, pode afetar até 90% dos portadores de psoríase no transcurso da doença, ao longo de suas vidas.

    The main objective of DIRAC experiment is the measurement of the lifetime τ of the exotic hadronic atom consisting of π + and π - mesons. The lifetime of this atom is determined by the decay mode π + π - → π 0 π 0 due to the strong interaction. Through the precise relationship between the lifetime and the S-wave pion-pion scattering length difference |a 0 - a 2 | for isospin 0 and 2 (respectively), a measurement of τ with an accuracy of 10% will allow a determination of |a 0 - a 2 | at a 5% precision level. Pion-pion scattering lengths have been calculated in the framework of chiral perturbation theory with an accuracy below 5%. In this way DIRAC experiment will provide a crucial test of the chiral symmetry breaking scheme in QCD effective theories at low energies

    Soviet research in terrestrial decontamination appears to have paralleled that of the US in many respects. However, the probability exists that long-term evaluations of decontamination techniques (over 10 to 20 years) have been carried out at one nuclear accident site (a marked divergence from US experience). The area of aquatic decontamination seems to offer the most intriguing possibilities for new information acquisition from the USSR; at this point only its potential importance can be speculated upon

Nos pacientes, a regressão logística indicou associação com baciloscopia positiva e número de lesões cutâneas maior que cinco. A análise por árvore de decisão mostrou associação com baciloscopia, classificação de Madri, número de nervos acometidos e idade. Nos contatos, as duas análises indicaram as mesmas associações: classificação do caso-índice, idade e tipo de serviço de saúde. As variáveis que explicaram melhor a soropositividade, em menores de 18 anos, são aquelas associadas à maior carga bacilar. Assim, o teste ML Flow poderia ser utilizado também na infância para ajudar na correta classificação dos pacientes para tratamento e na identificação dos contatos com maior risco de desenvolver hanseníase.This article presents the results of a cross-sectional study involving 115 newly-diagnosed leprosy patients and 1,011 household contacts, all under the age of 18.

    Any successor to PETRA and PEP colliders was expected to extend the energy range to the region where the weak interaction effect becomes sizable in annihilation process. The aim was to reach the level, at which the all round study of the standard model can be performed in a clean system of e + e - collision. Also it was aimed to explore the energy region where top quark pair production is likely. Considering the available site for accelerator construction and the expected size of the electroweak interference effect, the target energy was set at 60 GeV at the lowest. TRISTAN-1 experiment is a big initial step in the long range physics program. The laboratory established the plan to move on to TRISTAN-2 (B Factory) project. The TRISTAN accelerator including the main storage ring, the time sequence of storage ring operation, three experimental groups of AMY, TOPAZ and VENUS, and so on are explained. The experiments on basic annihilation process, the search for new particles, the electroweak interaction, QCD studies and so on are reported. The optimum TRISTAN ring was estimated as 3 km in diameter, but the largest possible size in the site was 1/3 of that. Hard decision was made to equip the ring with unusually many accelerating RF cavities and to apply superconducting technology. (K.I.)

For the development of a set of guidelines for the facilitation of citizens’ initiatives by local governments, we are experimenting with this method. It offers good opportunities for modeling interventions by testing their instrumental validity –the usefulness for the intended practical purposes. At the same time design experiments are also useful for evaluating the empirical validity of theoretical arguments and the further development of these arguments in the light of empirical evidence (by using e.g. the technique of pattern matching. We describe how we have applied this methodology in two cases and discuss our research approach. We encountered some unexpected difficulties, especially in the cooperation with professionals and citizens. These difficulties complicate the valid attribution of causal effects to the use of the new instrument. However, our preliminary conclusion is that design experiments are useful in our field of study

    In 1987, Westinghouse Hanford Company began operating a first-generation integrated safeguards system in the Plutonium Finishing Plant storage vaults. This Vault Safety and Inventory System is designed to integrate data into a computer-based nuclear material inventory monitoring system. The system gathers, in real time, measured physical parameters that generate nuclear material inventory status data for thousands of stored items and sends tailored report to the appropriate users. These data include canister temperature an bulge data reported to Plant Operations and Material Control and Accountability personnel, item presence and identification data reported to Material Control and Accountability personnel, and unauthorized item movement data reported to Security response forces and Material Control and Accountability personnel. The Westinghouse Hanford Company's experience and operational benefits in using this system for reduce radiation exposure, increase protection against insider threat, and real-time inventory control are discussed in this paper

By this online study one presents both the obstacles encountered and the recommendations for such a type of management that the present and future mangers must take into account. What motivated the respondent Romanian managers most to open their own business is the independence it offered them. They work in the field they have liked since they were young. The second reason was the perspective to have an additional income from the business development. The third argument in favour of opening a business is the possibility to assure the balance between personal life and career.

    In situ active experiments on the nonlinear wave-wave and wave-particle interactions in the ionospheric plasma were performed by a Japanese sounding rocket K-9M-41. Both spontaneously and artificially stimulated plasma waves in the VLF range were observed. When a large amplitude electron plasma wave was transmitted from the rocket, parametrically excited ion acoustic waves were observed in addition to natural emissions such as whistlers, LHR emissions, and hisslike emissions. It was also found that 'risers' were triggered by the LHR emissions, which seem to be very similar to a phenomenon of the so-called ASE (artificially stimulated emissions). When a slow electron beam with energy lower than 3 eV was ejected from the rocket, a new type of periodic U-shaped discrete emission was observed which was excited through a wave-particle interaction. The frequency of these emissions is lower than the LHR frequency and decreases as the beam energy is increased. Spectrograms of the observed plasma are presented, and some are analyzed theoretically.

    Full Text Available Despite the importance of human taeniasis/bovine cysticercosis for public and animal health and the economy, its actual epidemiological status in Brazil is not well-studied. We sought to assess the epidemiological profile of this zoonosis in the rural area of Viçosa County, Minas Gerais, Brazil. The prevalence of bovine cysticercosis was 0.42%, whereas no case of human taeniasis was diagnosed. Factors favoring the persistence of zoonosis were identified. These included the supply of untreated water to animals, animals raised for slaughter without sanitary supervision, poor mechanization of raising techniques, and the use of untreated water for human consumption. Bovine meat for human consumption acquired in the city or from the farm itself was characterized as a risk factor for bovine cysticercosis (Odds Ratio (OR =16.77; pApesar da importância do complexo teníase-cisticercose bovina para a saúde pública, animal e para a economia, a realidade epidemiológica da ocorrência dessas zoonoses no Brasil é pouco conhecida.

    2005-01-01

    In 2005 a governmental decision for continue the project for construction of Belene NPP was adopted. In case of start of this significant project in short terms, a good option will be to utilize the already achieved experience by the modernization program of units 5 and 6 of Kozloduy NPP. The process of construction of new NPP is associated with significant amount of engineering, civil construction works, equipment order and delivery, installation works, testing and commissioning activities. It is vital necessity to have optimal technology, strict organization for project implementation and excellent documentation. From technical point of view the experience from the modernization of units 5 and 6 of Kozloduy NPP will be very important in case of utilization of similar types of WWER 1000 units. According to the 'Feasibility study for construction of Belene NPP', the most favorable option is to accomplish the already partially constructed Unit 1 on the basis of upgraded WWER B-320 design - WWER 1000 B-392, in order to fulfill IEC 331-3A, IEC 332-3A, and of US NRC Regulatory Guide 1.70 and to construct the second unit on the basis of ASE WWER/1000 B-466. However, for any type of unit selected, the achieved experience will be an important basis. This article is focused mostly on the modernization aspects of some electrical systems of Kozloduy NPP

    Full Text Available Enteric parasitosis remains an important public health problem in many areas around the world including in Brazil, and it is frequently associated with poverty and lack of sanitation facilities. Research carried out over the course of a year revealed that 96.6% (28/29 of children randomly selected from a 'landless farm workers' settlement in Araras, São Paulo, aged 4 - 15 years, presented Giardia intestinalis cysts. After referral to the neighborhood Health Office, all the children received tinidazole, given as a single dose of 50 mg/kg and 12 months later, new fecal samples were collected and analyzed. Despite the low adherence to the study, a high percentage (64.3% - 9/14 of the children remained positive for the parasite. This study showed a high positivity of giardiasis in child residents of the settlement, even after treatment; adults were not sensitized to the study and did not collected and/or deliver children fecal samples. The precarious living conditions are consistent with a high susceptibility to parasitic diseases, suggesting that the treatment of the infected individuals without identifying and eradicating the means of contamination is simply a palliative measure.Enteroparasitoses continuam a ser um importante problema de saúde pública em muitas áreas ao redor do mundo, bem como no Brasil, e está frequentemente associada com a pobreza e à falta de saneamento básico.

Na metodologia foram utilizados alguns recursos da informática, como o programa KARDS , gerenciador da base de dados, e o software JARGÃO, que possibilitou a tarefa de analisar em linguagem natural os depoimentos dos pacientes, obtidos por meio de entrevista composta por duas perguntas abertas. Os resultados encontrados evidenciaram que após o diagnóstico da doença a maioria dos pacientes estudados apresentava preocupações e manifestava algum tipo de mudança em relação à família, aos amigos, ao emprego e a si próprios. As preocupações estavam relacionadas principalmente à possibilidade de transmitir a doença, especialmente para os familiares, e à incerteza da cura. As mudanças diziam respeito especialmente ao aparecimento de sintomas que, segundo os pacientes, poderiam provocar reações discriminatórias por parte de outras pessoas. Esses fatos levavam os pacientes a não contar aos amigos sobre sua doença.The purpose of this study was to identify leprosy patients' psychosocial problems experienced after they were informed about their diagnosis.

Tax planning is one of the legal example of using loopholes. On the contraty for fiscal authorities, doing tax avoidance as a mean of tax planning could potentially harmful for the government and, therefore, the government follows by using remedies of fiscal correction. This study aims to understand and to evaluate anti-tax avoindance law and regulations in Indonesia and identify whether or not there are several tax loopholes may provided resulting in negative benefits for the fiscal aouthority. From the field research finding by using indepth interview and participatory observation, it is evident that the most common practice of tax avoidance are the use of transfer pricing and thin capitalization schemes. Those two schemes were usually exploited to give optimum benefits of loopholes in tax laws. Thus, we acknowledge that anti-­tax avoidance regulations administered by the government in the context of good regulation process is still imperfect, to the fact that those regulations and law were still left behind some loopholes that potentially used to perform tax avoidance by the tax payer, therefore government would not get optimal revenue tax payers. Moreover, Indonesian anti-tax avoidance policy also lagged behind newest practical issues which are more complex and difficult to detect.

    Thin films of amorphous selenium have been prepared by thermal evaporation. DC conductivity measurements were carried out on these films in the temperature range between 208 and 322 deg. K. Above room temperature, the dark conductivity is thermally activated with activation energy E σ 1.05 ± 0.08 eV. For temperatures below 285 deg. K, an increase in the dark current is observed, which is interpreted in terms of a shift of the Fermi level that makes more states available for a hopping process. (letter to the editor)

    Full Text Available Pesantren is a religious educational institution managed by the society that is called as Pengasuh. Therefore, Pengasuh is a leader in a community. The educational background of Pengasuh effects activities developed in it. Furthermore, the activities in pesantren relate to the students’ competence and skills. In the modern and global world, the students’ competence and skills should be the primary consideration in developing program at Pesantren. One of the competencies and skills that must be mastered by the students are foreign-language skills. This article discussed about Pesantren Empowerment through the Development of Foreign Language Skills Program to Create an Islamic Generation. This was a research article that used Research and Development Design. This research was conducted at Pesantren I'anatut Tholibin Mojokerto. The first step of this research was to do Need Analysis by using questionaire and interview. Based on the results of questionaire and interview, the researchers developed a program to empower pesantren. The results of this research will be useful for pengasuh, because the result of this research will give a real contribution for pesantren in the form of program that is related to the competence and skills of students as a form of empowerment for pesantren

    Full Text Available Aspect based opinion mining investigates deeply, the emotions related to one’s aspects. Aspects and opinion word identification is the core task of aspect based opinion mining. In previous studies aspect based opinion mining have been applied on service or product domain. Moreover, product reviews are short and simple whereas, social reviews are long and complex. However, this study introduces an efficient model for social reviews which classifies aspects and opinion words related to social domain. The main contributions of this paper are auto tagging and data training phase, feature set definition and dictionary usage. Proposed model results are compared with CR model and Naïve Bayes classifier on same dataset having accuracy 98.17% and precision 96.01%, while recall and F1 are 96.00% and 96.01% respectively. The experimental results show that the proposed model performs better than the CR model and Naïve Bayes classifier.

    Full Text Available Acute appendicitis is the most common surgical condition of acute abdomen. Approximately 7 percent of the population will have appendicitis during their lifetime, with the peak incidence occurring between 10 through 30 years-old. Obstruction of the appendix lumen with subsequent bacterial infection initiates the pathophysiological sequence of acute appendicitis. Obstruction may have multiple causes, including fecalith, lymphoid hyperplasia (related to viral illnesses, including upper respiratory infection, mononucleosis, and gastroenteritis, foreign bodies, carcinoid tumor, and parasites. In Asia, Africa and Latin America, Enterobius vermicularis has been reported as the main parasite that causes appendix obstruction. Rarely, Taenia sp., has been pointed as a cause of parasitic appendicitis. We reported a 30 years-old patient clinically diagnosed with acute appendicitis. The appendectomy was performed through a McBurney incision. The patient's convalescence was uneventful, and he was discharged from hospital 48 hours after operation. Histological examination of the appendix showed acute appendicitis, and it was found a parasite (Taenia sp. lying inside of the appendix lumen at a transverse section. He has received 10 mg/Kg weight of praziquantel for taeniasis treatment.

    Full Text Available The administration of behavioral and experimental paradigms for psychology research is hindered by lack of a coordinated effort to develop and deploy standardized paradigms. While several frameworks (de Leeuw (2015; McDonnell et al. (2012; Mason and Suri (2011; Lange et al. (2015 have provided infrastructure and methods for individual research groups to develop paradigms, missing is a coordinated effort to develop paradigms linked with a system to easily deploy them. This disorganization leads to redundancy in development, divergent implementations of conceptually identical tasks, disorganized and error-prone code lacking documentation, and difficulty in replication. The ongoing reproducibility crisis in psychology and neuroscience research (Baker (2015; Open Science Collaboration (2015 highlights the urgency of this challenge: reproducible research in behavioral psychology is conditional on deployment of equivalent experiments. A large, accessible repository of experiments for researchers to develop collaboratively is most efficiently accomplished through an open source framework. Here we present the Experiment Factory, an open source framework for the development and deployment of web-based experiments. The modular infrastructure includes experiments, virtual machines for local or cloud deployment, and an application to drive these components and provide developers with functions and tools for further extension. We release this infrastructure with a deployment (http://www.expfactory.org that researchers are currently using to run a set of over 80 standardized web-based experiments on Amazon Mechanical Turk. By providing open source tools for both deployment and development, this novel infrastructure holds promise to bring reproducibility to the administration of experiments, and accelerate scientific progress by providing a shared community resource of psychological paradigms.

    Set to begin data taking at the end of 2018, the Belle II experiment is the next-generation B-factory experiment hosted at KEK in Tsukuba, Japan. The experiment represents the cumulative effort from the collaboration of experimental and detector physics, computing, and software development. Taking everything learned from the previous Belle experiment, which ran from 1998 to 2010, Belle II aims to probe deeper than ever before into the field of heavy quark physics. By achieving an integrated luminosity of 50 ab−1 and accumulating 50 times more data than the previous experiment across its lifetime, along with a rewritten analysis framework, the Belle II experiment will push the high precision frontier of high energy physics. This paper will give an overview of the key components and development activities that make the Belle II experiment possible.

    1978-01-01

    The target diagnostics which are being used and planned in current laser driven ICF Experiments are described. Most of these diagnostics can be easily applied to future ion-beam fusion experiments. The status of laser fusion diagnostics has been much improved in the last 5 years and further improvements can be expected and should be available when the first ICF experiments using ion beams are performed. As an example, x-ray temporal and spatial resolutions are now approximately 5 psec and 3 μm, which is approximately a factor of 4 better than the resolution reported in the first implosion experiments. As one plans ahead for ion-beam fusion experiments it should be emphasized that high yield experiments are easier to diagnose provided adequate shielding is employed. However, in the event that the first high yield experiments fail it will be necessary to have diagnostics available to determine where the problems lie. In laser fusion it is interesting to note that higher laser powers are required now for breakeven experiments than first anticipated, mainly because some aspects of the laser-interaction physics were not recognized until the experiments were carefully diagnosed. Thus as has been pointed out, it may be necessary to increase the energy of the ion-beam driver to enable us to do breakeven experiments with high confidence

  20. Popper's Thought Experiment Reinvestigated

    Richardson, Chris; Dowling, Jonathan

    2012-02-01

    Karl Popper posed an interesting thought experiment in 1934. With it, he meant to question the completeness of quantum mechanics. He claimed that the notion of quantum entanglement leads to absurd scenarios that cannot be true in real life and that an implementation of his thought experiment would not give the results that QM predicts. Unfortunately for Popper, it has taken until recently to perform experiments that test his claims. The results of the experiments do not refute QM as Popper predicted, but neither do they confirm what Popper claimed QM predicted. Kim and Shih implemented Popper's thought experiment in the lab. The results of the experiment are not clear and have instigated many interpretations of the results. The results show some correlation between entangled photons, but not in the way that Popper thought, nor in the way a simple application of QM might predict. A ghost-imaging experiment by Strekalov, et al. sheds light on the physics behind Popper's thought experiment, but does not try to directly test it. I will build the physics of Popper's thought experiment from the ground up and show how the results of both of these experiments agree with each other and the theory of QM, but disprove Popper.

    Abstract: This chapter introduces a psycho-societal approach to theorizing learning, combining a materialist theory of socialization with a hermeneutic interpretation methodology. The term "approach" indicates the intrinsic connection between theory, empirical research process and epistemic subject....... Learning is theorized as dynamic subjective experience of (socially situated) realities, counting on individual subjectivity as well as subjective aspects of social interaction. This psycho-societal theory of subjective experiences conceptualizes individual psychic development as interactional experience...... of societal relations, producing an inner psycho-dynamic as a conscious and unconscious individual resource in future life. The symbolization of immediate sensual experiences form an individual life experience of social integration, language use being the medium of collective, social experience (knowledge...

    This report describes two experiments in which SBS would be expected to play an important role. In the first experiment, we find a clear signature of the Brillouin backscatter of a short (100 psec) pulse from a long (approx. 50 μm) gradient length gas target plasma. The second experiment used much longer (approx. 1 nsec) pulses on spherical glass shell targets. These experiments were done with both narrow ( 30A) bandwidth laser light. Using one-dimensional, spherically symmetric fluid simulations, we have attempted to model many of the laser-plasma interaction processes which combine to determine the amount of absorbed energy in the long-pulse experiments. These simulations indicate that modest laser bandwidths are successful in reducing the level of SBS at the irradiances ( 15 W/cm 2 ) used in these experiments

    In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

    Russell, R. A.

    1988-01-01

    A system study to develop the definition of a structural flight experiment for a large precision segmented reflector on the Space Station was accomplished by the Boeing Aerospace Company for NASA's Langley Research Center. The objective of the study was to use a Large Deployable Reflector (LDR) baseline configuration as the basis for focusing an experiment definition, so that the resulting accommodation requirements and interface constraints could be used as part of the mission requirements data base for Space Station. The primary objectives of the first experiment are to construct the primary mirror support truss and to determine its structural and thermal characteristics. Addition of an optical bench, thermal shield and primary mirror segments, and alignment of the optical components, would occur on a second experiment. The structure would then be moved to the payload point system for pointing, optical control, and scientific optical measurement for a third experiment. Experiment 1 will deploy the primary support truss while it is attached to the instrument module structure. The ability to adjust the mirror attachment points and to attach several dummy primary mirror segments with a robotic system will also be demonstrated. Experiment 2 will be achieved by adding new components and equipment to experiment one. Experiment 3 will demonstrate advanced control strategies, active adjustment of the primary mirror alignment, and technologies associated with optical sensing.

    The G0 experiment measures the parity-violating asymmetries in elastic electron-proton and quasi-elastic electron-deuteron scattering over the momentum transfers 0.12 ≤ Q2 ≤ 1.0 GeV2. These asymmetries are sensitive to the strange-quark contribution to the charge and magnetization distributions of the proton. The experiment is conducted at Jefferson Laboratory using a toroidal spectrometer designed to detect forward scattered recoil protons and backward scattered elastic and quasi-elastic electrons. The forward angle experiment was completed in 2004, and the backward angle phase of the experiment is currently taking place

  16. Radiochemical solar neutrino experiments

    International Nuclear Information System (INIS)

    Rich, R.; Spiro, M.

    1993-01-01

    This review covers the three presently running radiochemical solar neutrino experiments, namely the Chlorine, SAGE, and GALLEX experiments. The focus of the review is on a discussion of statistical consistency checks of the available data. The chlorine radiochemical experiment is conceptually simple and shows no strong indication of any statistical anomalies. It still forms the basis of the solar neutrino problem. Each of the two gallium experiments show internal statistical consistency. SAGE's recent preliminary results are consistent with the published GALLEX results. If this convergence is confirmed by a more definitive analysis, this would suggest that the combined result of the two gallium experiments, SAGE and GALLEX, be used for comparisons with theoretical expectations. 5 refs., 15 figs

    1992-01-01

    A sequence of reactor and related experiments has been a central element of a senior-level laboratory course at Pennsylvania State University (Penn State) for more than 20 yr. A new experiment has been developed where the students program and operate a computer controller that manipulates the speed of a secondary control rod to regulate TRIGA reactor power. Elementary feedback control theory is introduced to explain the experiment, which emphasizes the nonlinear aspect of reactor control where power level changes are equivalent to a change in control loop gain. Digital control of nuclear reactors has become more visible at Penn State with the replacement of the original analog-based TRIGA reactor control console with a modern computer-based digital control console. Several TRIGA reactor dynamics experiments, which comprise half of the three-credit laboratory course, lead to the control experiment finale: (a) digital simulation, (b) control rod calibration, (c) reactor pulsing, (d) reactivity oscillator, and (e) reactor noise

  18. Molybdenum solar neutrino experiment

    International Nuclear Information System (INIS)

    Wolfsberg, K.; Cowan, G.A.; Bryant, E.A.

    1984-01-01

    The goal of the molybdenum solar neutrino experiment is to deduce the 8 B solar neutrino flux, averaged over the past several million years, from the concentration of 98 Tc in a deeply buried molybdenum deposit. The experiment is important to an understanding of stellar processes because it will shed light on the reason for the discrepancy between theory and observation of the chlorine solar neutrino experiment. Possible reasons for the discrepancy may lie in the properties of neutrinos (neutrino oscillations or massive neutrinos) or in deficiencies of the standard solar model. The chlorine experiment only measures the 8 B neutrino flux in current times and does not address possible temporal variations in the interior of the sun, which are also not considered in the standard model. In the molybdenum experiment, we plan to measure 98 Tc (4.2 Myr), also produced by 8 B neutrinos, and possibly 97 Tc (2.6 Myr), produced by lower energy neutrinos

The cryogenic test facility in hall 180 for ATLAS magnets. High Energy Physics experiments have frequently adopted cryogenic versions of their apparatus to achieve optimal performance, and those for the LHC will be no exception. The two largest experiments for CERN's new flagship accelerator, ATLAS and CMS, will both use large superconducting magnets operated at 4.5 Kelvin - almost 270 degrees below the freezing point of water. ATLAS also includes calorimeters filled with liquid argon at 87 Kelvin. For the magnets, the choice of a cryogenic version was dictated by a combination economy and transparency to emerging particles. For the calorimeters, liquid argon was selected as the fluid best suited to the experiment's physics requirements. High Energy Physics experiments are the result of worldwide collaborations and...

  3. Understanding customer experience.

    Meyer, Christopher; Schwager, Andre

    2007-02-01

    Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention.

  4. Conducting interactive experiments online.

    Arechar, Antonio A; Gächter, Simon; Molleman, Lucas

    2018-01-01

    Online labor markets provide new opportunities for behavioral research, but conducting economic experiments online raises important methodological challenges. This particularly holds for interactive designs. In this paper, we provide a methodological discussion of the similarities and differences between interactive experiments conducted in the laboratory and online. To this end, we conduct a repeated public goods experiment with and without punishment using samples from the laboratory and the online platform Amazon Mechanical Turk. We chose to replicate this experiment because it is long and logistically complex. It therefore provides a good case study for discussing the methodological and practical challenges of online interactive experimentation. We find that basic behavioral patterns of cooperation and punishment in the laboratory are replicable online. The most important challenge of online interactive experiments is participant dropout. We discuss measures for reducing dropout and show that, for our case study, dropouts are exogenous to the experiment. We conclude that data quality for interactive experiments via the Internet is adequate and reliable, making online interactive experimentation a potentially valuable complement to laboratory studies.

    Russell, Richard A.; Gates, Richard M.

    1988-01-01

    A study was performed to develop the definition of a structural flight experiment for a large precision segmented reflector that would utilize the Space Station. The objective of the study was to use the Large Deployable Reflector (LDR) baseline configuration for focusing on experiment definition activity which would identify the Space Station accommodation requirements and interface constraints. Results of the study defined three Space Station based experiments to demonstrate the technologies needed for an LDR type structure. The basic experiment configurations are the same as the JPL baseline except that the primary mirror truss is 10 meters in diameter instead of 20. The primary objectives of the first experiment are to construct the primary mirror support truss and to determine its structural and thermal characteristics. Addition of the optical bench, thermal shield and primary mirror segments and alignment of the optical components occur on the second experiment. The structure will then be moved to the payload pointing system for pointing, optical control and scientific optical measurement for the third experiment.

    1991-02-01

    In the process of preparing for pyrophoricity experiments involving uranium, we conducted hydriding and air-exposure experiments on titanium. In these experiments the hydriding reactions and response to air-exposure was generally within the range expected based on work reported by others. One aberrant behavior was a sudden weight gain followed by a significant weight loss. We speculate that loss may be due to hydrogen evolution from the TiH 2 resulting from local heating by oxidation reactions. We verified that titanium is not pyrophoric at temperatures less than 750 degree C. 18 refs. 1 fig

    Recent (first or/and the best) results from the neutrino experiments are reviewed and their implications for the theory are discussed. The sense of the experiments is the searching for neutrino masses, mixing and interactions beyond the standard model. Present laboratory experiments give upper bounds on the masses and the mixing which are at the level of predictions of the ''electroweak see-saw''. Positive indications of nonzero lepton mixing follow from studies of the solar and atmospheric neutrinos. (author). 95 refs, 11 figs

    The Red Sage campaign is a series of subcritical dynamic plutonium experiments designed to measure ejecta. Nightshade, the first experiments in Red Sage scheduled for fiscal year 2019, will measure the amount of ejecta emission into vacuum from a double-­shocked plutonium surface. To address the major technical risks in Nightshade, a Level 2 milestone was developed for fiscal year 2016. Silverleaf, a series of four experiments, was executed at the Los Alamos National Laboratory in July and August 2016 to demonstrate a prototype of the Nightshade package and to satisfy this Level 2 milestone. This report is documentation that Red Sage Level 2 milestone requirements were successfully met.

    In December 1965, an experiment took place at The Independent Art Space in Copenhagen (Den Frie Kunstbygning). Short named POEX65, it was looking to create and activate POetry EXperiments across artistic genres and formats (thus, in essence, making a POetry EXposition). The POEX65 event framed many...... to be able to analyse the phenomena found at POEX65. Here I will use the notion of the ‘ontological theatre’ (Pickering), which, according to Pickering, is acted out in experimental art productions. The experiment could thus be seen as an ‘agency-realism’ – as an ‘act’ of relations across the aesthetics...

    Full Text Available Transient response such as ringing in a control system can be reduced or removed by velocity feedback. It is a useful control technique that should be covered in the relevant engineering laboratory courses. We developed velocity feedback experiments using two different low cost technologies, viz., operational amplifiers and microcontrollers. These experiments can be easily integrated into laboratory courses on feedback control systems or microcontroller applications. The intent of developing these experiments was to illustrate the ringing problem and to offer effective, low cost solutions for removing such problem. In this paper the pedagogical approach for these velocity feedback experiments was described. The advantages and disadvantages of the two different implementation of velocity feedback were discussed also.

    2003-01-01

    A neutrino factory based on a muon storage ring is the ultimate tool for studies of neutrino oscillations, including possibly leptonic CP violation. It is also the first step towards muon colliders. The performance of this new and promising line of accelerators relies heavily on the concept of ionisation cooling of minimum ionising muons, for which much R&D is required. The concept of a muon ionisation cooling experiment has been extensively studied and first steps are now being taken towards its realisation by a joint international team of accelerator and particle physicists. The aim of the workshop is to to explore at least two versions of an experiment based on existing cooling channel designs. If such an experiment is feasible, one shall then select, on the basis of effectiveness, simplicity, availability of components and overall cost, a design for the proposed experiment, and assemble the elements necessary to the presentation of a proposal.

    Every 21st century student is expected to develop science literacy skills. As this is not part of Serbian national curriculum yet, we decided to introduce it with this project. Experiment-o-mania provides students to experience science in different and exciting way. It makes opportunity for personalized learning offering space and time to ask (why, where, how, what if) and to try. Therefore, we empower young people with skills of experimenting, and they love science back. They ask questions, make hypothesis, make problems and solve them, make mistakes, discuss about the results. Subsequently this raises the students' interest for school curriculum. This vision of science teaching is associated with inquiry-based learning. Experiment-o-mania is the unique and recognizable teaching methodology for the elementary school Drinka Pavlović, Belgrade, Serbia. Experiment-o-mania implies activities throughout the school year. They are held on extra class sessions, through science experiments, science projects or preparations for School's Days of science. Students learn to ask questions, make observations, classify data, communicate ideas, conduct experiments, analyse results and make conclusions. All science teachers participate in designing activities and experiments for students in Experiment-o-mania teaching method. But they are not alone. Teacher of fine arts, English teachers and others also take part. Students have their representatives in this team, too. This is a good way to blend knowledge among different school subject and popularize science in general. All the experiments are age appropriate and related to real life situations, local community, society and the world. We explore Fibonacci's arrays, saving energy, solar power, climate change, environmental problems, pollution, daily life situations in the country or worldwide. We introduce great scientists as Nikola Tesla, Milutin Milanković and sir Isaac Newton. We celebrate all relevant international days, weeks

    Chang, C.; Yodh, G.; Cutts, D.; Lanou, R.; Engels, E.; Kramer, M.; Danby, G.

    1977-01-01

    A study was made to examine the effects which raising the ISA from 200 x 200 GeV to 400 x 400 GeV would have on the ''canonical'' experiments. These were ''canonical'' in the sense that they span the full range of foreseeable physics and have served as topics in previous Summer Studies and Workshops which resulted in quite explicit hardware designs and experimental goals. The study results indicate that all of the ''canonical'' experiments survive. Some are actually improved, some are unaffected, and some require changes which are suggested. In general, the 90 0 experiments are relatively unaffected. The single arm small angle spectrometer, the wide aperture (FATS-WASP) spectrometer and the Coulomb interference experiment have the largest number of modifications suggested. No uniqueness to these solutions are claimed, and there may be more desirable radical approaches. It is, however, felt that the 400 x 400 GeV ISA not only permits the work on conceptual experiments from previous Summer Studies to be taken over entirely, but indicates areas of improvement in many of them. Specifics of the individual experiments are discussed

  17. Inverse Cerenkov experiment

    International Nuclear Information System (INIS)

    Kimura, W.D.

    1993-01-01

    The final report describes work performed to investigate inverse Cherenkov acceleration (ICA) as a promising method for laser particle acceleration. In particular, an improved configuration of ICA is being tested in a experiment presently underway on the Accelerator Test Facility (ATF). In the experiment, the high peak power (∼ 10 GW) linearly polarized ATF CO 2 laser beam is converted to a radially polarized beam. This is beam is focused with an axicon at the Cherenkov angle onto the ATF 50-MeV e-beam inside a hydrogen gas cell, where the gas acts as the phase matching medium of the interaction. An energy gain of ∼12 MeV is predicted assuming a delivered laser peak power of 5 GW. The experiment is divided into two phases. The Phase I experiments, which were completed in the spring of 1992, were conducted before the ATF e-beam was available and involved several successful tests of the optical systems. Phase II experiments are with the e-beam and laser beam, and are still in progress. The ATF demonstrated delivery of the e-beam to the experiment in Dec. 1992. A preliminary ''debugging'' run with the e-beam and laser beam occurred in May 1993. This revealed the need for some experimental modifications, which have been implemented. The second run is tentatively scheduled for October or November 1993. In parallel to the experimental efforts has been ongoing theoretical work to support the experiment and investigate improvement and/or offshoots. One exciting offshoot has been theoretical work showing that free-space laser acceleration of electrons is possible using a radially-polarized, axicon-focused laser beam, but without any phase-matching gas. The Monte Carlo code used to model the ICA process has been upgraded and expanded to handle different types of laser beam input profiles

  18. Experiments in computing: a survey.

    Science.gov (United States)

    Tedre, Matti; Moisseinen, Nella

    2014-01-01

    Experiments play a central role in science. The role of experiments in computing is, however, unclear. Questions about the relevance of experiments in computing attracted little attention until the 1980s. As the discipline then saw a push towards experimental computer science, a variety of technically, theoretically, and empirically oriented views on experiments emerged. As a consequence of those debates, today's computing fields use experiments and experiment terminology in a variety of ways. This paper analyzes experimentation debates in computing. It presents five ways in which debaters have conceptualized experiments in computing: feasibility experiment, trial experiment, field experiment, comparison experiment, and controlled experiment. This paper has three aims: to clarify experiment terminology in computing; to contribute to disciplinary self-understanding of computing; and, due to computing's centrality in other fields, to promote understanding of experiments in modern science in general.

  19. Staged theta pinch experiments

    1976-01-01

    Two implosion heating circuits are being experimentally tested. The principal experiment in the program is the 4.5-m-long Staged Theta Pinch (STP). It uses two relatively low energy (50kJ and 100 kJ), high voltage (125 kV) capacitor banks to produce the theta pinch plasma inside the 20 cm i.d. quartz discharge tube. A lower voltage (50 kV), higher energy (750 kJ) capacitor bank is used to contain the plasma and provide a variable amount of adiabatic compression. Because the experiment produces a higher ratio of implosion heating to compressional heating than conventional theta pinches, it should be capable of producing high temperature plasmas with a much larger ratio of plasma radius to discharge tube radius than has been possible in the past. The Resonant Heating Experiment (RHX) in its initial configuration is the same as a 0.9-m-long section of the high voltage part of the STP experiment and all the plasma results here were obtained with the experiment in that configuration. Part of the implosion bank will be removed and a low inductance crowbar added to convert it to the resonant heating configuration. (U.K.)

    A MHD experiment is being constructed which will have the possibility of showing dynamo action: the self--generation of currents from fluid motion. The design allows sufficient experimental flexibility and diagnostic access to study a variety of issues central to dynamo theory, including mean--field electrodynamics and saturation (backreaction physics). Initially, helical flows required for dynamo action will be driven by propellers embedded in liquid sodium. The flow fields will first be measured using laser doppler velocimetry in a water experiment with an identical fluid Reynolds number. The magnetic field evolution will then be predicted using a MHD code, replacing the water with sodium; if growing magnetic fields are found, the experiment will be repeated with sodium.

  1. Thought experiment with tritium

    International Nuclear Information System (INIS)

    Anderson, H.F.; Everhart, J.L.; Hobrock, D.L.; Seabaugh, P.W.

    1995-01-01

    An experiment is proposed in which a minimum of thirty (30) grams of tritium is packaged as lithium tritide in a steel container weighing several kilograms. After decontamination of the outside surface, calorimetry measurements would be made, and the unit would be weighed very accurately. After several decades, the calorimeter and weight measurements would be repeated. If the weight measurements could be made with the required accuracy, it would be possible to correlate the observed change in mass with the total energy emitted (calculated from the mean energy measured by calorimetry) over the time interval. If successful, this experiment would, in the opinion of the authors, be the first laboratory experiment to directly verify the equivalency of mass and energy. 4 refs., 2 figs., 3 tabs

    The Insertable B-Layer (IBL) is the inner most pixel layer in the ATLAS experiment, which was installed at 3.3 cm radius from the beam axis in 2014 to improve the tracking performance. To cope with the high radiation and hit occupancy due to proximity to the interaction point, a new read-out chip and two different silicon sensor technologies (planar and 3D) have been developed for the IBL. After the long shut-down period over 2013 and 2014, the ATLAS experiment started data-taking in May 2015 for Run-2 of the Large Hadron Collider (LHC). The IBL has been operated successfully since the beginning of Run-2 and shows excellent performance with the low dead module fraction, high data-taking efficiency and improved tracking capability. The experience and challenges in the operation of the IBL is described as well as its performance.

    Slovenian Nuclear Safety Administration (SNSA) has developed its own system for tracking, screening and evaluating the operating experiences of the nuclear installations. The SNSA staff regularly tracks the operating experiences throughout the world and screens them on the bases of applicability for the Slovenian nuclear facilities. The operating experiences, which pass the screening, are thoroughly evaluated and also recent operational events in these facilities are taken into account. If needed, more information is gathered to evaluate the conditions of the Slovenian facilities and appropriate corrective actions are considered. The result might be the identification of the need for modification at the licensee, the need for modification of internal procedures in the SNSA or even the proposal for the modification of regulations. Information system helps everybody to track the process of evaluation and proper logging of activities. (author)

    As part of the Institute for Creative Technologies and the School of Cinematic Arts at the University of Southern California, the Mixed Reality lab develops technologies and techniques for presenting realistic immersive training experiences. Such experiences typically place users within a complex ecology of social actors, physical objects, and collections of intents, motivations, relationships, and other psychological constructs. Currently, it remains infeasible to completely synthesize the interactivity and sensory signatures of such ecologies. For this reason, the lab advocates mixed reality methods for training and conducts experiments exploring such methods. Currently, the lab focuses on understanding and exploiting the elasticity of human perception with respect to representational differences between real and virtual environments. This paper presents an overview of three projects: techniques for redirected walking, displays for the representation of virtual humans, and audio processing to increase stress.

      The article take its point of departure in the pressure of the experience economy on European cities - a pressure which in recent years has found its expression in a number of comprehensive transformations of the physical and architectural environments, and new eventscapes related to fun...... and cultural experience are emerging. In the discussion of the transformation into the ‘experience economy' relevant to cities and urban areas we rarely find an analysis of the physical and spatial implications of this transformation. However, the physical, cultural and democratic consequences...... clear goals related to the improvement of social interaction, performance and cultural exchange. The article contains three sections. in section one, we present three European cases in order to relate to the wider international debate and development. In section two we present the main theoretical...

    Full Text Available An experiment investigated the effect of a make-believe fantasy mode of problem presentation on reasoning about valid conditional syllogisms in three groups of 5-year-old children: a school children from middle-class families in England; b school children from middle-class families in Brazil; and, c children from low SES families in Brazil who had never gone to school. Previous investigations had reported that the use of a fantasy context elicited significantly more logically appropriate responses from school children than did other contexts, and that children with school experiences made significantly more logically appropriate responses than did children without school experience. The present investigation extended these findings to show that the beneficial effects of a fantasy context extended to lower-class illiterate children who never had been exposed to schooling

    The aim of these experiments is to search for several rare-decay modes of the muon and the pion and to study these decay modes should they be observed. In Exps. 400/445, the muon-number-nonconserving decays μ + αe + e + e - , μ + →e + γ, and μ + →e + γγ are being sought with a sensitivity to branching ratios of about 10 -11 relative to ordinary muon decay. Experiment 726 will search for the charge-conjugation-violating decay π 0 →3γ with a sensitivity to a branching ratio as small as 10 -9 relative to ordinary π 0 decay. Experiment 888 is a study of radiative pion decay π + →e + nu/sub e/γ

    This paper describes experiments with a design technique that we denote cooperative prototyping. The experiments consider design of a patient case record system for municipal dental clinics in which we used HyperCard, an off the shelf programming environment for the Macintosh. In the ecperiments we...... tried to achieve a fluent work-like evaluation of prototypes where users envisioned future work with a computer tool, at the same time as we made on-line modifications of prototypes in cooperation with the users when breakdown occur in their work-like evaluation. The experiments showed...... that it was possible to make a number of direct manipulation changes of prototypes in cooperation with the users, in interplay with their fluent work-like evaluation of these. However, breakdown occurred in the prototyping process when we reached the limits of the direct manipulation support for modification. From...

    This paper discusses how front-line employees can play an important role in innovation processes that lead tourism companies from service production to experience creation. The increasing focus on experiential value by customers in general (Sundbo and Sørensen, 2013) puts pressure on service...... companies to move from functional service production to creating experiences (Pine and Gilmore, 2013). This is also the case in tourism companies. In tourism, most encounters between employees and tourists operate on a service logic (Sørensen and Jensen, 2015). Thus, we suggest there is a value potential...... in developing such encounters into experience encounters focusing on the co-creation of experiential value. While frontline employees are central for service quality they are mostly not included in systematised innovation processes in tourism companies. These companies are often hierarchically organised...

  13. Compact ignition experiments

    Angelini, A.; Coppi, B.; Nassi, M.

    1992-01-01

    This paper reports on high magnetic field experiments which can be designed to investigate D-T ignition conditions based on present-day experimental results and theoretical understanding of plasma phenomena. The key machine elements are: large plasma currents, compact dimensions, tight aspect ratios, moderate elongations and significant triangularities of the plasma column. High plasma densities, strong ohmic heating, the needed degree of energy confinement, good plasma purity and robust stability against ideal and resistive instabilities can be achieved simultaneously. The Ignitor design incorporates all these characteristics and involves magnet technology developments, started with the Alcator experiment, that use cryogenically cooled normal conductors

  14. Photon mass experiment

    1983-01-01

    A Coulomb null experiment is described that enables physics students to obtain rigorous upper bounds on photon mass. The experimenter searches for subnanovolt signals that would escape a closed shell were photon mass to be positive. The approach can be adapted for several college levels. At the simplest level, a ''miniature'' low-cost experiment allows a student to verify the exponent ''-2'' in Coulomb's law to eight or more decimal places. An advanced student given a full-size apparatus (at greater cost) can obtain mass bounds very close to the established laboratory limit

    The thermal-relic mechanism for the production of dark-matter in the early universe, combined with the precision measurements of the cosmic microwave background and the lack of observation of dark matter at the LHC, motivates the search for dark matter in the mass range between 1 MeV and 1 GeV. We describe the concept for the Light Dark Matter Experiment (LDMX), which could carry out such a search using the missing-momentum technique. The experiment would utilize a unique high-rate, low-curre...

    Neoliberalism is a powerful narrative that has shaped processes of urban economic development across the globe. This paper reports on four nascent ‘new economic’ narratives which represent fundamentally different imaginaries of the urban economy. Experiments informed by these narratives challenge...... the dominant neoliberal logic in four key dimensions: What is the purpose of economic development? What are the preferred distributive mechanisms? Who governs the economy? What is the preferred form of economic organisation? The emergence of these experiments illustrates that cities are spaces where counter...

    Twelve experiments in radiochemistry, nuclear chemistry, radiation detection and radiation measurement are presented which have been tested in teaching practice. Criteria of selection were minimum apparative expenditure, preparation time, radiation exposure, and danger of incorporation or contamination. The experiments will teach students how to handle unsealed radioactive materials within a fraction of a permissible values and thus train them in radiochemical techniques of working. Theoretical, historical and topical aspects are mentioned in order to give the students some background. A detailed bibliography of relevant publications is given. (orig./HP) [de

A backstop was introduced in one of the experiments and a new method was developed where information obtained from the backstop can be used in the inversion...... algorithm. Independent in-situ aerosol plume concentrations were obtained from a simultaneous tracer gas experiment with SF6, and comparisons with the two lidars were made. The study shows that the reproducibility of the lidars is within 15%, including measurements from both sides of a plume...

    To push forward the necessarily lengthy preparations for experiments at the proposed US Superconducting Super Collider, a Workshop on Experiments, Detectors and Experimental Areas was held at Berkeley from 7 to 17 July. Participants looked ahead to the task of extracting physics (like the search for Higgs particles, supersymmetry or other heavy quarks and leptons) from the chaos of hadron collisions at 20 TeV beam energies with luminosities in excess of 10 32 . The door would also have to be left open for unexpected physics in these higher energy regions

In the context of architecture accessibility has become a design concept of its own. It is generally described as ensuring...... physical access to the built environment by accommodating physical disabilities. While the existing concept of accessibility ensures the physical access of everyone to a given space, sensory accessibility ensures the choice of everyone to stay and be able to participate and experience....
