    Full Text Available The língu maquista is an old dialect which is part of the Portuguese heritage in Macau. This dialect, also known by patois, was commonly spoken among Macanese families until the end of the 19th century. However, from 1930 on, the lingu maquista started to fall into disuse, and nowadays it is on the verge of extinction. Quoting José dos Santos Ferreira: «in a few years now, no traces of this dialect will remain over, except for a few pale remembrances, as the nostalgic sound of a sweet melody pregnant of old memoirs». This article makes the apologia of the life and spirit of a dialect that proved to be able to absorb the Camonian prose and poetry. In addition, it testifies for the remanent marks of the Portuguese Language, linking together three continents and three geographical regions: Portugal, Macau and Brazil.

  8. Retention of clinical trial participants in a study of nongonococcal urethritis (NGU), a sexually transmitted infection in men.

    Lee, Jeannette Y; Lensing, Shelly Y; Schwebke, Jane R

    2012-07-01

    Nongonococcal urethritis (NGU), an inflammation of the urethra not caused by gonorrhea, is the most common urethritis syndrome seen in men in the United States. It is a sexually transmitted infection commonly caused by Chlamydia trachomatis, a pathogen which occurs more frequently in African-American men compared to white men. The purpose of this study was to investigate factors related to retention of study participants in a randomized, double-blinded clinical trial that evaluated four treatment regimens for the treatment of NGU. After the one-week treatment period, follow-up visits were scheduled during days 15-19 and days 35-45. Participants were phoned prior to scheduled appointments to encourage attendance, and contacted after missed appointments to reschedule their clinic visits. Of the 305 male study participants, 298 (98%) were African-American, 164 (54%) were 25 years of age or younger, and 80 (31%) had a post-secondary school education. The overall retention rate was 75%. Factors associated with study completion were educational level attained and clinical center. Participants with higher levels of education were more likely to complete the study. Clinical centers with the highest retention rates also provided the highest monetary incentives for participation. The retention rate for this study suggests that strategies are needed for improving the proportion of study participants that complete a clinical trial among young men with a sexually transmitted disease. These strategies may include increasing contacts with study participants to remind them of scheduled study visits using text messaging or social media and the use of financial incentives.

Furthermore, I also attempt a comparative analysis between the biblical quotations incorporated within uv and those preeminent in the Byzantine and Ruthenian sermons dedicated to the feast of the Transfiguration.

    To determine if female partners of men with pathogen-negative non-gonococcal urethritis (NGU) are at risk of genital infection. Secondary data analysis using health records from a large sexually transmitted disease clinic in Melbourne of 1710 men and their female partners attending on the same day from January 2006 to April 2015. Proportions of female partners with symptoms suggesting genital infection or pelvic inflammatory disease (PID) were determined for: (1) men with NGU and no Chlamydia trachomatis or Mycoplasma genitalium (referred to as pathogen-negative NGU) (n = 91); 2) men with urethral C. trachomatis (n = 176); 3) men with urethral M. genitalium (n = 26); and 4) asymptomatic men (n = 652). Female partners of men with pathogen-negative NGU experienced deep pelvic pain (adjusted odds ratio [AOR], 2.2; 95% confidence interval [CI], 1.1-4.4), post coital bleeding (AOR, 2.4; 95% CI, 1.2-4.9), and dysuria (AOR, 3.7; 95% CI, 1.6-8.6) more commonly and were diagnosed with PID more commonly (AOR, 4.8; 95% CI, 2.1-11.3) than the female partners of asymptomatic men. Pelvic inflammatory disease was not more likely to be diagnosed in the female partners of men with genital warts (AOR, 1.4; 95% CI, 0.5-4.4) or candidiasis (AOR, 1.2; 95% CI, 0.4-3.5) than the female partners of asymptomatic men. The female partners of men with chlamydia experienced post coital bleeding more (AOR, 1.9; 95% CI, 1.0-3.6) and were more likely to be diagnosed with PID (AOR, 3.6; 95% CI, 1.6-8.0). The female partners of men with pathogen-negative NGU may be at increased risk of genital infection, even if a recognised pathogen is not identified in the man.

  1. Replacing the CCSDS Telecommand Protocol with the Next Generation Uplink (NGU)

    Science.gov (United States)

    Kazz, Greg J.; Greenberg, Ed; Burleigh, Scott C.

    2012-01-01

    The current CCSDS Telecommand (TC) Recommendations 1-3 have essentially been in use since the early 1960s. The purpose of this paper is to propose a successor protocol to TC. The current CCSDS recommendations can only accommodate telecommand rates up to approximately 1 mbit/s. However today's spacecraft are storehouses for software including software for Field Programmable Gate Arrays (FPGA) which are rapidly replacing unique hardware systems. Changes to flight software occasionally require uplinks to deliver very large volumes of data. In the opposite direction, high rate downlink missions that use acknowledged CCSDS File Delivery Protocol (CFDP)4 will increase the uplink data rate requirements. It is calculated that a 5 mbits/s downlink could saturate a 4 kbits/s uplink with CFDP downlink responses: negative acknowledgements (NAKs), FINISHs, End-of-File (EOF), Acknowledgements (ACKs). Moreover, it is anticipated that uplink rates of 10 to 20 mbits/s will be required to support manned missions. The current TC recommendations cannot meet these new demands. Specifically, they are very tightly coupled to the Bose-Chaudhuri-Hocquenghem (BCH) code in Ref. 2. This protocol requires that an uncorrectable BCH codeword delimit the TC frame and terminate the randomization process. This method greatly limits telecom performance since only the BCH code can support the protocol. More modern techniques such as the CCSDS Low Density Parity Check (LDPC)5 codes can provide a minimum performance gain of up to 6 times higher command data rates as long as sufficient power is available in the data. This paper will describe the proposed protocol format, trade-offs, and advantages offered, along with a discussion of how reliable communications takes place at higher nominal rates.

    Directory of Open Access Journals (Sweden)

    Liina Unt

    2014-12-01

    Full Text Available The comparison between theatre and playing has spread on many levels, from metaphors to sayings, aesthetic concepts to deterministic models. This paper examines scenography as an active play environment. Play, in the context of theatre space, is defined according to the classical characteristic features of playing: spatial and temporal limits, fictionality that runs in parallel with everyday reality, and direct involvement.  The paper focuses on the specific aspects of play environment as it appears in the Tartu New Theatre’s performances of „The Death of the Author“ and „The Beatles of Vanemuine“. Both productions are set in fictional locations with a visually static set design. Both are unique in that different locations are created without changing the physical space on stage – places appear and disappear through the performances, created by an odd textual allusion or two, or the audience’s imagination. The changes can be understood through the audience’s corporal perception, which this paper interprets using Merleau-Ponty’s phenomenological concept of corporeity.  Using Tartu New Theatre’s stage practice and Hans-Georg Gadamer’s hermeneutic aesthetics, the paper aims to answer the question: what is the aesthetic structure of such stage environments and how can an environmental experience be created, if the direct interference in space is minimal. Gadamer’s aesthetic concept revolves around play, interpreting works of art as a structure, a meaningful whole that can be presented and comprehended repeatedly. However, he qualifies that the structure, itself, is also a play as, despite a theoretic unity, it only exists when it is played. In this case, the scenography becomes an environment with open meanings, where attributing meaning and function happens through the agreements made during the act of playing, which don’t necessarily also imply physical changes to the environment. The environment is an agreed-upon space-time that is created by a shared corporal presence wherein understanding of the meanings is dependent on participation, i.e. taking part in the agreement that creates the game.  When the invisible, yet perceptible space created by the scenography is analysed using Gadamer’s aesthetics, the main issues become presentation and presence. The „invisible scenography“ is perceived only in the moment in which it is presented. Though the fictional room partially materialises (through the audiencestage relationship, elements of design, etc., creating the scenography as non-visual spaces provokes a conflict of perception, where there is a disparity between the visible space and its use or meaning. And this, in turn, requires a constant re-interpretation of the agreements. Interpreting the visual, which has historically been scenography’s main role, as a play changes its function and meaning.

  16. Are Ureaplasma spp. a cause of nongonococcal urethritis? A systematic review and meta-analysis.

    Directory of Open Access Journals (Sweden)

    Nan Zhang

    Full Text Available BACKGROUND: Nongonococcal urethritis (NGU is the most common male reproductive tract syndrome. Ureaplasmas spp. including U. urealyticum and U. parvum, have been increasingly reported to be implicated in NGU. However, there are still many contradictions about their pathogenic role in NGU. AIMS: The goals of this study were to evaluate the association of Ureaplasmas spp. with NGU, and to compare the prevalence of Ureaplasmas spp. infection in China relative to the world average. METHODS: A systematic review and meta-analysis was conducted following standard guidelines for meta-analysis. The quality of included studies was assessed by Newcastle-Ottawa scale. RESULTS: A total of seven studies involving 1,507 NGU patients and 1,223 controls were eligible for meta-analysis. There was no significant difference in the Ureaplasma spp. positive rate between the NGU and control groups. However, the U. urealyticum positive rate was significantly higher in NGU patients compared to controls; the U. parvum positive rate was significantly higher in controls compared to NGU patients. Furthermore, within the NGU patient group, the positive rate of U. urealyticum was significantly higher than that of U. parvum, whereas within the control group, the opposite trend was observed. Compared to the world average, a significantly higher positive rate of Ureaplasma spp. was observed in both the NGU and control groups in China. CONCLUSIONS: Our analysis supports that U. urealyticum, but not U. parvum, is an etiological agent in NGU. More detailed studies of these two species in China and the world could contribute to a better understanding of the epidemiology and pathogenesis, and facilitate the development of better strategies for treatment and prevention of NGU.

    Nongonococcal urethritis (NGU) is the most common male reproductive tract syndrome. Ureaplasmas spp. including U. urealyticum and U. parvum, have been increasingly reported to be implicated in NGU. However, there are still many contradictions about their pathogenic role in NGU. The goals of this study were to evaluate the association of Ureaplasmas spp. with NGU, and to compare the prevalence of Ureaplasmas spp. infection in China relative to the world average. A systematic review and meta-analysis was conducted following standard guidelines for meta-analysis. The quality of included studies was assessed by Newcastle-Ottawa scale. A total of seven studies involving 1,507 NGU patients and 1,223 controls were eligible for meta-analysis. There was no significant difference in the Ureaplasma spp. positive rate between the NGU and control groups. However, the U. urealyticum positive rate was significantly higher in NGU patients compared to controls; the U. parvum positive rate was significantly higher in controls compared to NGU patients. Furthermore, within the NGU patient group, the positive rate of U. urealyticum was significantly higher than that of U. parvum, whereas within the control group, the opposite trend was observed. Compared to the world average, a significantly higher positive rate of Ureaplasma spp. was observed in both the NGU and control groups in China. Our analysis supports that U. urealyticum, but not U. parvum, is an etiological agent in NGU. More detailed studies of these two species in China and the world could contribute to a better understanding of the epidemiology and pathogenesis, and facilitate the development of better strategies for treatment and prevention of NGU.

    The aetiology of non-gonococcal urethritis (NGU) remains unexplained in 30-40% of patients. Urine samples from men attending Swedish sexually transmitted disease clinics were examined by species-specific quantitative PCRs for Chlamydia trachomatis, Mycoplasma genitalium, Trichomonas vaginalis, Ureaplasma urealyticum, U. parvum, adenovirus, herpes simplex virus, Neisseria meningitidis, Haemophilus influenzae, Moraxella catarrhalis and Streptococcus pneumoniae. A total of 187 men with acute NGU (symptoms ≤ 30 days) and 24 with chronic NGU (symptoms < 30 days) were cases, and 73 men without NGU were controls. Number of lifetime sexual partners was negatively associated with U. urealyticum bacterial load. C. trachomatis and M. genitalium were associated with NGU, as was U. urealyticum, with bacterial loads ≥ 1.3 × 103 genome equivalents/ml urine. Virus and H. influenzae might explain a few NGU cases, but the aetiology in at least 24% of patients with acute NGU was unexplained. In multivariate analysis, detection of U. urealyticum was significantly more common in acute NGU (20%) compared with controls (11%).

    To clarify the clinical efficacy of STFX for patients with non-gonococcal urethritis (NGU), including chlamydial urethritis and Mycoplasma genitalium-positive urethritis, this study included male patients with NGU who were 20 years old or older. The pathogens, including Chlamydia trachomatis, M. genitalium and Ureaplasma urealyticum, were detected by nucleic acid amplification tests and the patients were treated with sitafloxacin 100 mg twice daily for 7 days. Microbiological and clinical efficacies were assessed for the patients with NGU posttreatment. Among the 208 patients enrolled in this study, data for a total of 118 patients could be analyzed. The median age was 32 (20-61) years. The median duration from the completion of treatment to the second visit was 21 (14-42) days. There were 68 pathogen-positive NGU cases and 50 with NGU without any microbial detection. Microbiological cure was achieved in 95.6% of the pathogen-positive NGU patients. Total clinical cure was achieved in 91.3% (105/115). In this study, STFX was able to eradicate 95.7% of C. trachomatis, 93.8% of M. genitalium and 100% of U. urealyticum. The results of our clinical research indicate that the STFX treatment regimen should become a standard regimen recommended for patients with NGU. In addition, this regimen is recommended for patients with M. genitalium-positive NGU.

    Objective To assess the role of Ureaplasma urealyticum and Ureaplasma parvum in patients with non-gonococcal urethritis (NGU) using specimens from a previously reported study of NGU. Methods Species-specific PCR assays for U urealyticum and U parvum were used to detect these organisms in specimens from men enrolled in a case–control study based in a Seattle STD clinic in order to evaluate their association with NGU. Urethritis was defined by clinical examination and the presence of inflammation on Gram stained smear. Controls had normal examination findings and no evidence of inflammation on Gram stain smear or by the leucocyte esterase test. Results U urealyticum was detected in 26% (31/119) of cases and 16% (19/117) of controls, resulting in an association with NGU (adjusted odds ratio (aOR)=2.3, 95% CI 1.04 to 4.9) after adjusting for age, race, history of prior urethritis and other NGU pathogens (Chlamydia trachomatis, Mycoplasma genitalium). The association of U urealyticum and NGU was strongest in white men urethritis. The strong effect in younger white men and high rates in controls may suggest variability in virulence among U urealyticum strains or in host innate or acquired immunity. PMID:20460265

    Background. Ureaplasmas have been inconsistently associated with nongonococcal urethritis (NGU). We evaluated the association of the newly differentiated species Ureaplasma urealyticum (UU) and Ureaplasma parvum (UP) with NGU using 2 separate control groups. Methods. Case patients were men who attended a sexually transmitted disease (STD) clinic in Seattle, Washington, during the period 2007–2009 with NGU (defined as visible urethral discharge and/or ≥5 polymorphonuclear neutrophils per high-powered field; n = 329). Control subjects were STD clinic attendees (n = 191) and emergency department (ED) attendees (n = 193) without NGU. Polymerase chain reaction assays detected UU and UP in ureaplasma culture-positive urine. Multivariable logistic regression was used to assess the associations of UU and UP with NGU. Results. UU was only marginally associated with NGU in aggregate multivariable analyses, irrespective of control group (adjusted odds ratio [aOR]STD-control, 1.6 [95% confidence interval {CI}, 0.9–2.8]; aORED-control, 1.7 [95% CI, 0.97–3.0]). This association was significantly stronger when analyses were restricted to men with fewer lifetime sex partners (urethral pathogen. PMID:21917901

    To confirm the efficacy of the treatment regimen with oral levofloxacin (LVFX) 500 mg once daily for 7 days for patients with non-gonococcal urethritis (NGU), we evaluated the microbiological and clinical outcomes of the regimen in those patients. We finally evaluated 53 patients with symptomatic NGU and 5 patients with asymptomatic NGU. As a result of microbiological examinations, 19 of the symptomatic patients were diagnosed as having non-gonococcal chlamydial urethritis (NGCU); 13 had non-gonococcal non-chlamydial urethritis (NGNCU), and 21 had urethritis without any microbial detection. Five of the asymptomatic patients were diagnosed as having NGCU. Microbiological cure was achieved in 91% of the 32 patients with symptomatic NGU and in 80% of the 5 patients with asymptomatic NGCU. Clinical cure was obtained in 92% of the 53 patients with symptomatic NGU. The microbiological eradication rate for Chlamydia trachomatis was 92% in 24 patients. As for other organisms, the microbiological eradication rate for Mycoplasma genitalium was 60% in 5 patients and that for Ureaplasma urealyticum was 100% in 10. The microbiological and clinical efficacy of oral LVFX 500 mg once daily for 7 days for the patients with NGU was the same for the azithromycin (AZM) 1,000 mg single dose that we previously reported. The eradication rates of C. trachomatis and U. urealyticum in the treatment regimen with LVFX 500 mg were high enough in the clinical setting; however, for M. genitalium, the rate was relatively inferior to that with AZM.

    2012-09-01

    Acute nongonococcal urethritis (NGU) is one of the commonest sexually transmitted infections affecting men and women. The diagnosis of NGU has traditionally required microscopic evidence of urethritis. However, a significant proportion of patients with urethral symptoms do not have microscopic evidence of urethritis. The purpose of the present study was to evaluate the analytical performance of the UF1000i, a recently introduced fluorescence flow cytometer intended for urinalysis purposes which provides new analytical features that seem particularly suitable for microbiological diagnostics, for ruling out NGU or predicting the presence of infection. The Sysmex UF1000i is a flow cytometry analyzer capable of quantifying a lot of particles, including bacteria (BACT) and white blood cells (WBCs). To evaluate the analytical performance of the UF1000i as a method for ruling out NGU, we examined 200 urethral smear samples, collected in a new liquid transport medium (Copan), and compared the UF1000i results with standard culture/molecular and microscopic Gram stain results. With instrument cut-off values of 200 BACT x 10^6/L and 500 WBCs x 10^6/L, we obtained a sensitivity of 84%, a specificity of 82%, and a high negative predictive value (96%). Culture/molecular detection of pathogens remains the gold standard technique for the diagnosis of NGU. However, the Sysmex UF1000i is capable of improving the efficiency of NGU presumptive diagnosis, providing results in a few minutes, with a high negative predictive value and high values of sensitivity.

    N. Ramos-Pedroza

    2017-01-01

    Full Text Available A robust nonlinear control law that achieves trajectory tracking control for unmanned aerial vehicles (UAVs equipped with synthetic jet actuators (SJAs is presented in this paper. A key challenge in the control design is that the dynamic characteristics of SJAs are nonlinear and contain parametric uncertainty. The challenge resulting from the uncertain SJA actuator parameters is mitigated via innovative algebraic manipulation in the tracking error system derivation along with a robust nonlinear control law employing constant SJA parameter estimates. A key contribution of the paper is a rigorous analysis of the range of SJA actuator parameter uncertainty within which asymptotic UAV trajectory tracking can be achieved. A rigorous stability analysis is carried out to prove semiglobal asymptotic trajectory tracking. Detailed simulation results are included to illustrate the effectiveness of the proposed control law in the presence of wind gusts and varying levels of SJA actuator parameter uncertainty.

     Empirical antibiotic therapy for nongonococcal urethritis (NGU) and cervicitis is aimed at Chlamydia trachomatis, but Mycoplasma genitalium, which also commonly causes undiagnosed NGU, necessitates treatment with macrolides or fluoroquinolones rather than doxycycline, the preferred chlamydia treatment. Prevalence of M. genitalium and associated genotypic markers of macrolide and fluoroquinolone resistance among men symptomatic of urethritis were investigated. Genetic diversity of M. genitalium populations was determined to infer whether findings were applicable beyond our setting.  Mycoplasma genitalium and other NGU pathogens were detected using nucleic acid amplification methods, and DNA sequencing was used to detect genotypic resistance markers of macrolide and fluoroquinolone antibiotics in 23S ribosomal RNA, gyrA, gyrB, and parC genes. MG191 single-nucleotide polymorphism typing and MG309 variable number tandem analysis were combined to assign a dual locus sequence type (DLST) to each positive sample.  Among 217 men, M. genitalium prevalence was 16.7% (95% confidence interval [CI], 9.5%-24.0%) and C. trachomatis prevalence was 14.7% (95% CI, 7.8%-21.6%) in NGU cases. Nine of 22 (41%; 95% CI, 20%-62%) patients with M. genitalium were infected with DLSTs possessing genotypic macrolide resistance and 1 patient was infected with a DLST having genotypic fluoroquinolone resistance. Typing assigned M. genitalium DLSTs to 2 major clusters, broadly distributed among previously typed international strains. Genotypic macrolide resistance was spread within these 2 clusters.  Mycoplasma genitalium is a frequent undiagnosed cause of NGU in this population with rates of macrolide resistance higher than those previously documented. Current guidelines for routine testing and empirical treatment of NGU should be modified to reduce treatment failure of NGU and the development of further resistance.

    Several microorganisms cause non-gonococcal urethritis (NGU). Failure to eradicate Mycoplasma genitalium from the urethra could be associated with persistent or recurrent urethritis; thus, the choice of antibiotics with activities potent enough to eradicate M. genitalium is crucial in the treatment of NGU. In in vitro studies, sitafloxacin has been shown to be highly active against Chlamydia trachomatis and M. genitalium. We treated 89 males with NGU, including 15 patients with persistent or recurrent NGU and 1 patient with post-gonococcal urethritis, with a 100-mg twice-daily dose regimen of sitafloxacin to assess its efficacy against NGU. We examined first-void urine samples for the presence of C. trachomatis, M. genitalium, Ureaplasma parvum, and Ureaplasma urealyticum. After treatment, we evaluated 73 patients for clinical outcomes and 44 for microbiological outcomes. Symptoms were alleviated in 62 (84.9%) patients, who were judged clinically cured. Microorganisms detected before treatment were eradicated in 42 (95.5%) patients, who were judged microbiologically cured. Regarding microbiological outcomes of specific microorganisms, eradication rates of C. trachomatis (n = 33), M. genitalium (n = 11), and U. urealyticum (n = 10) were 100%, 100%, and 80.0%, respectively. In all 5 patients with M. genitalium-positive persistent or recurrent NGU who had experienced treatment failures with antibiotics, the mycoplasma was eradicated. These results suggested that the sitafloxacin regimen used, which was effective on both M. genitalium and C. trachomatis infections, could be useful as an appropriate option as first- and second-line treatment of NGU.

  5. Identification and characterization of novel microRNAs from Schistosoma japonicum.

    Full Text Available BACKGROUND: Schistosomiasis japonica remains a major public health problem in China. Its pathogen, Schistosoma japonicum has a complex life cycle and a unique repertoire of genes expressed at different life cycle stages. Exploring schistosome gene regulation will yield the best prospects for new drug targets and vaccine candidates. MicroRNAs (miRNAs are a highly conserved class of noncoding RNA that control many biological processes by sequence-specific inhibition of gene expression. Although a large number of miRNAs have been identified from plants to mammals, it remains no experimental proof whether schistosome exist miRNAs. METHODOLOGY AND RESULTS: We have identified novel miRNAs from Schistosoma japonicum by cloning and sequencing a small (18-26 nt RNA cDNA library from the adult worms. Five novel miRNAs were identified from 227 cloned RNA sequences and verified by Northern blot. Alignments of the miRNAs with corresponding family members indicated that four of them belong to a metazoan miRNA family: let-7, miR-71, bantam and miR-125. The fifth potentially new (non conserved miRNA appears to belong to a previously undescribed family in the genus Schistosome. The novel miRNAs were designated as sja-let-7, sja-miR-71, sja-bantam, sja-miR-125 and sja-miR-new1, respectively. Expression of sja-let-7, sja-miR-71 and sja-bantam were analyzed in six stages of the life cycle, i.e. egg, miracidium, sporocyst, cercaria, schistosomulum, and adult worm, by a modified stem-loop reverse transcribed polymerase chain reaction (RT-PCR method developed in our laboratory. The expression patterns of these miRNAs were highly stage-specific. In particular, sja-miR-71 and sja-bantam expression reach their peaks in the cercaria stage and then drop quickly to the nadirs in the schistosomulum stage, following penetration of cercaria into a mammalian host. CONCLUSIONS: Authentic miRNAs were identified for the first time in S. japonicum, including a new schistosome

    Acute nongonococcal urethritis (NGU) is one of the commonest sexually transmitted infections affecting men. The role of genital mycoplasmas including Mycoplasma genitalium in HIV infected men with NGU is still not known. The aim of this study was to determine the isolation pattern/detection of genital mycoplasma including M. genitalium in HIV infected men with NGU and to compare it with non HIV infected individuals. One hundred male patients with NGU (70 HIV positive, 30 HIV negative) were included in the study. Urethral swabs and urine samples obtained from patients were subjected to semi-quantitative culture for Mycoplasma hominis and Ureaplasama urealyticum, whereas M. genitalium was detected by PCR from urine. The primers MgPa1 and MgPa3 were selected to identify 289 bp product specific for M. genitalium. Chalmydia trachomatis antigen detection was carried out by ELISA. M. genitalium and M. hominis were detected/isolated in 6 per cent of the cases. M. genitalium was more common amongst HIV positive cases (7.1%) as compared to HIV negative cases (3.3%) but difference was not statistically significant. Co-infection of C. trachomatis and U. urealyticum was found in two HIV positive cases whereas, C. trachomatis and M. hominis were found to be coinfecting only one HIV positive individual. M. genitalium was found to be infecting the patients as the sole pathogen. Patients with NGU had almost equal risk of being infected with M. genitalium, U. urealyticum or M. hominis irrespective of their HIV status. M.genitalium constitutes one of the important causes of NGU besides other genital mycoplasmas.

    A non-syndromic approach to treatment of people with non-gonococcal urethritis (NGU) requires identification of pathogens and understanding of the role of those pathogens in causing disease. The most commonly detected and isolated micro-organisms in the male urethral tract are bacteria belonging to the family of Mycoplasmataceae, in particular Ureaplasma urealyticum and Ureaplasma parvum. To better understand the role of these Ureaplasma species in NGU, we have performed a prospective analysis of male patients voluntarily attending a drop in STI clinic in Oslo. Of 362 male patients who were tested for NGU using microscopy of urethral smears, we found the following sexually transmissible micro-organisms: 16% Chlamydia trachomatis, 5% Mycoplasma genitalium, 14% U. urealyticum, 14% U. parvum and 5% Mycoplasma hominis. We found a high concordance in detecting in turn U. urealyticum and U. parvum using 16s rRNA gene and ureD gene as targets for nucleic acid amplification testing (NAAT). Whilst there was a strong association between microscopic signs of NGU and C. trachomatis infection, association of M. genitalium and U. urealyticum infections in turn were found only in patients with severe NGU (>30 polymorphonuclear leucocytes, PMNL/high powered fields, HPF). U. parvum was found to colonise a high percentage of patients with no or mild signs of NGU (0-9 PMNL/HPF). We conclude that urethral inflammatory response to ureaplasmas is less severe than to C. trachomatis and M. genitalium in most patients and that testing and treatment of ureaplasma-positive patients should only be considered when other STIs have been ruled out.

    Nongonococcal urethritis (NGU) is a common clinical syndrome, but no etiological agent is identified in a significant proportion of cases. Whether the spectrum of pathogens differs between heterosexual men (MSW) and men who have sex with men (MSM) is largely unstudied but of considerable clinical relevance. A retrospective review was done using the electronic medical record database of Melbourne Sexual Health Centre, Australia. Cases were first presentations of symptomatic acute NGU with ≥ 5 polymorphonuclear leukocytes (PMNL)/high-powered field (HPF) on urethral Gram stain between January 2006 and December 2011. First-stream urine was tested for Chlamydia trachomatis and Mycoplasma genitalium by PCR. Demographic, laboratory, and behavioral characteristics of cases were examined by univariate and multivariable analyses. Of 1,295 first presentations of acute NGU, 401 (32%; 95% confidence interval [CI] of 29 to 34%) had C. trachomatis and 134 (11%; 95% CI of 9 to 13%) had M. genitalium detected. MSM with acute NGU were less likely to have C. trachomatis (adjusted odds ratio [AOR] = 0.4; 95% CI of 0.3 to 0.6) or M. genitalium (AOR = 0.5; 95% CI of 0.3 to 0.8) and more likely to have idiopathic NGU (AOR = 2.4; 95% CI of 1.8 to 3.3), to report 100% condom use for anal/vaginal sex (AOR = 3.6; 95% CI of 2.7 to 5.0), or to have engaged in sexual activities other than anal/vaginal sex (AOR = 8.0; 95% CI of 3.6 to 17.8). Even when C. trachomatis or M. genitalium was detected, MSM were more likely than MSW to report consistent condom use (OR = 4.7; 95% CI of 2.6 to 8.3). MSM with acute NGU are less likely to have the established bacterial sexually transmitted infections (STIs) and more likely to report protected anal sex or sexual activity other than anal sex prior to symptom onset than MSW. These data suggest that the etiologic spectrum of pathogens differs between MSM and MSW in acute NGU and that relatively low-risk practices are capable of inducing acute NGU. Copyright

  10. Robust Nonlinear Regulation of Limit Cycle Oscillations in UAVs Using Synthetic Jet Actuators

    Directory of Open Access Journals (Sweden)

    Natalie Ramos Pedroza

    2014-09-01

    Full Text Available In this paper, a synthetic jet actuators (SJA-based nonlinear robust controller is developed, which is capable of completely suppressing limit cycle oscillations (LCO in UAV systems with parametric uncertainty in the SJA dynamics and unmodeled external disturbances. Specifically, the control law compensates for uncertainty in an input gain matrix, which results from the unknown airflow dynamics generated by the SJA. Challenges in the control design include compensation for input-multiplicative parametric uncertainty in the actuator dynamic model. The result was achieved via innovative algebraic manipulation in the error system development, along with a Lyapunov-based robust control law. A rigorous Lyapunov-based stability analysis is utilized to prove asymptotic LCO suppression, considering a detailed dynamic model of the pitching and plunging dynamics. Numerical simulation results are provided to demonstrate the robustness and practical performance of the proposed control law.

    We retrieved clinical data of 13 men having herpes simplex virus (HSV)-induced non-gonococcal urethritis (NGU) without visible herpetic lesions. They visited a clinic in Sendai, Japan, between April 2013 and December 2015. All the men complained of dysuria. Meatitis was observed in 9 of the 13 men. Mononuclear cells were observed in the urethral smears from 9 men. The 13 men were treated with azithromycin or sitafloxacin regimen. First-voided urine (FVU) specimens became negative for HSV in 8 of the 10 men who returned to the clinic after antibacterial treatment, and urethritis symptoms were alleviated. However, herpetic lesions were observed at the follow-up visits in 3 men, and 2 of them were still positive for HSV in their FVU. HSV could be a cause of acute urethritis without causing visible herpetic lesions. The shedding of HSV from the urethra would spontaneously cease with alleviation of urethritis symptoms in most cases of HSV-induced NGU without antiviral therapy. However, new herpetic lesions could be developed in some cases. Early antiviral therapy is beneficial for patients with HSV infections. The development of meatitis and the mononuclear cell response in the urethral smear could be helpful to diagnose HSV-induced NGU. Therefore, we should presumptively initiate anti-HSV therapy for patients with signs and symptoms suggestive of HSV-induced NGU at their first presentation.

    Background. Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), and Trichomonas vaginalis (TV) are sexually transmitted infections (STIs) associated with nongonococcal urethritis (NGU). We assessed their predictors and persistence after treatment. Methods. We analyzed data from an NGU treatment trial among symptomatic heterosexual men aged 16–45 years from STI clinics. Nucleic acid amplification tests detected CT, MG, and TV at baseline and at 1 and 4 weeks after therapy. Associations between variables and STI detection were investigated. Results. Among 293 participants, 44% had CT, 31% had MG, and 13% had TV at baseline. In multivariate analysis, CT infection was associated with young age and STI contact. Young age was also associated with MG, and having ≥1 new partner was negatively associated with TV. We detected persistent CT in 12% and MG in 44% of participants at 4 weeks after therapy, which were associated with signs and symptoms of NGU. Persistent CT was detected in 23% of participants after azithromycin treatment vs 5% after doxycycline treatment (P = .011); persistent MG was detected in 68% of participants after doxycycline vs 33% after azithromycin (P = .001). All but 1 TV infection cleared after tinidazole. Conclusions. Persistent CT and MG after treatment of NGU are common, and were associated with clinical findings and drug regimen. PMID:22615318

    We investigated the prevalence of various genital organisms in 268 men with (cases) and 237 men without (controls) urethral symptoms/signs (urethral discharge, dysuria and/or urethral irritation) from two sexual health clinics in Sydney between April 2006 and November 2007. The presence of urethral symptoms/signs was defined as non-gonococcal urethritis (NGU) for this study. Specific aims were to investigate the role of Ureaplasma urealyticum in NGU and the prevalence of Mycoplasma genitalium in our population. Multiplex polymerase chain reaction-based reverse line blot (mPCR/RLB) assay was performed to detect 14 recognized or putative genital pathogens, including Chlamydia trachomatis, M. genitalium, U. urealyticum and U. parvum. U. urealyticum was associated with NGU in men without another urethral pathogen (odds ratio [OR] 2.0, 95% confidence interval [CI] 1.1-3.8; P = 0.04); this association remained after controlling for potential confounding by age and history of unprotected vaginal sex in the last four weeks (OR 2.0, 95% CI: 1.1-3.9; P = 0.03). C. trachomatis (OR 7.5, P urethral pathogens. Further research should investigate the role of U. urealyticum subtypes among heterosexual men with NGU.

    Full Text Available Introduction: Ureaplasma uriealyticum is one of the most important causes of Nongonococcal and Nonspecific urethritis (NGU & NSU in men. Mycoplasma hominis too has a causal role in NGU & NSU. This study aimed to investigate whether it is possible to detect Mycoplasma hominis and Ureaplasma uriealyticum in first voided urine samples in men suffering from NGU & NSU without complaints of urethral secretions and in women with clinical symptoms despite negative vaginal secretion culture test results. Methods: First voided urine samples were taken from 150 patients (21 women & 129 men suffering from NGU & NSU who referred to the Division of Bacteriology, School of Public Health, Tehran University of Medical Sciences in 2004-2005. Samples were examined by culture method. Results: Cultures were positive for Mycoplasma and Ureoplasma in 49 (32.6 % of the 150 samples. Of the 21 samples taken from women, 5 samples were positive for Mycoplasma & Ureoplasma (2 samples Mycoplasma, 3 samples Ureaplasma. Samples from 44 men were positive for Ureoplasma & Mycoplasma(17 samples Mycoplasma, 4 samples Ureaplasma and 23 samples were positive for both. Ureoplasma urealyticum was detected in 30 samples (20% and Mycoplasma hominis, was detected in 42 samples (28%. Conclusion: The results of this study provides evidence that culture tests can be done using voided urine in order to detect Mycoplasma hominis and ureaplasma urealyticum in patients suffering from Nongonococcal urethris; men who do not have urethral secretions and women with clinical symptoms despite negative vaginal secretion culture test results.

    Ureaplasma urealyticum could be a pathogen of non-gonococcal urethritis (NGU) in men. However, ureaplasma is often detected in men without NGU, and the proportion of cases possibly attributable to this pathogen is still undefined. We attempted to determine the bacterial loads of U. urealyticum significantly associated with NGU. The 16S rRNA genes of U. urealyticum were quantified by a real-time polymerase chain reaction-based assay in first-void urine (FVU) from 26 asymptomatic and 25 symptomatic men positive for U. urealyticum. The leucocyte counts in first-void urine (FVU) were determined as an objective measure of inflammatory response to ureaplasma in the hosts by automated quantitative urine particle analysis. Positive correlations were observed between copies of the 16S rRNA genes of U. urealyticum per ml and the leucocyte counts per µl in FVU (r = 0.49, p = 0.0003). Loads of ≥10(4) copies of the 16S rRNA gene of U. urealyticum/ml, corresponding to ≥5 × 10(3) cells of U. urealyticum/ml in FVU, were significantly associated with the presence of urethritis symptoms (p < 0.0001) and with higher leukocyte counts in FVU (p < 0.0001). The bacterial load of U. urealyticum, possibly of ≥5 × 10(3) cells of U. urealyticum/ml in FVU, could be significantly associated with the development of symptomatic NGU.

    Poor follow-up compliance of patients with infectious urethritis is a recognized and serious public health problem in Thailand. The aim of this study was to determine treatment outcomes and loss to follow-up rate of male patients with gonococcal urethritis (GU) and non-GU (NGU) at a sexually transmitted disease (STD) clinic at Thailand's tertiary hospital. This retrospective chart review of male patients who sought treatment at STDs Clinic, Siriraj Hospital, and who were diagnosed with GU and/or NGU was conducted during January 2007 to December 2014 study period. Two hundred and twenty-seven male urethritis patients were included in this study with a mean age was 29.5 years. GU and NGU were found in 120 (52.9%) and 107 (47.1%) of patients, respectively. Overall prevalence of GU and NGU during the 8-year study period at STD Clinic, Siriraj Hospital, was 8.6% and 7.8%, respectively. Ninety-six patients (42.3%) were lost to follow-up. Recurrent urethritis was found in 23.8% of patients, and HIV infection was identified in 11.6%. Mean age of patients lost to follow-up was 29 years. Compared with patients who attended every scheduled follow-up visit, men who have sex with men had a significantly lower rate of loss to follow-up ( P = 0.012). Almost half of patients with GU or NGU were lost to follow-up, and one-quarter had recurrent urethritis. Fast and easy access to services that provide accurate diagnostic testing and effective treatment should be a public health priority to prevent complications and reduce rates of disease transmission.

  4. Prediction of the persistence of Mycoplasma genitalium after antimicrobial chemotherapy by quantification of leukocytes in first-void urine from patients with non-gonococcal urethritis.

    Mycoplasma genitalium is regarded as another pathogen of male non-gonococcal urethritis (NGU). Failure to eradicate this mycoplasma is associated with persistent or recurrent NGU, but this mycoplasma is not routinely examined in clinical practice. In cases of M. genitalium-positive NGU, therefore, some criteria are needed to assess the success or failure of antimicrobial chemotherapy other than microbiological outcomes. We enrolled 49 men with M. genitalium-positive non-chlamydial NGU. At successive visits after treatment, we inquired about their symptoms, observed their urethral meatus for urethral discharge, and examined their first-void urine (FVU) for quantification of leukocytes and for the persistence of M. genitalium. M. genitalium was eradicated in 34 patients after treatment, whereas the mycoplasma persisted in 15. Urethritis symptoms and urethral discharges were not found to be predictors of the persistence of M. genitalium up to the 25th day after the start of treatment. Leukocyte counts in FVU from the patients with persistence of M. genitalium were significantly higher than those from the patients with eradication of the mycoplasma. Leukocyte counts of 10 leukocytes/μl or more between the 18th and 24th day after the start of treatment were most significantly associated with the persistence of M. genitalium. Quantification of leukocytes in FVU would appear to be crucial to judge the outcome of treatment in patients with non-chlamydial NGU and could be helpful to predict the persistence of M. genitalium after treatment when M. genitalium is not routinely examined in clinical specimens in clinical practice.

    Doxycycline, one of two recommended therapies for non-gonococcal urethritis (NGU), consists of a 7-day course of therapy (100 mg BID). Since suboptimal adherence may contribute to poor treatment outcomes, we examined the association between self-reported imperfect adherence to doxycycline and clinical and microbiologic failure among men with NGU. Men aged ≥16 years with NGU attending a Seattle, WA, sexually transmitted diseases clinic were enrolled in a double-blind, parallel-group superiority trial from January 2007 to July 2011. Men were randomised to active doxycycline/placebo azithromycin or placebo doxycycline/active azithromycin. Imperfect adherence was defined as missing ≥1 dose in 7 days. Urine was tested for Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), and Ureaplasma urealyticum-biovar 2 (UU-2) using nucleic acid amplification tests. Clinical failure (symptoms and ≥5 PMNs/HPF or discharge) and microbiologic failure (positive tests for CT, MG, and/or UU-2) were determined after 3 weeks. 184 men with NGU were randomised to active doxycycline and provided data on adherence. Baseline prevalence of CT, MG and UU-2 was 26%, 13% and 27%, respectively. 28% of men reported imperfect adherence, and this was associated with microbiologic failure among men with CT (aRR=9.33; 95% CI 1.00 to 89.2) and UU-2 (aRR=3.08; 95% CI 1.31 to 7.26) but not MG. Imperfect adherence was not significantly associated with clinical failure overall or for any specific pathogens, but it was more common among imperfectly adherent men with CT (aRR=2.63; 0.93-7.41, p=0.07). Adherence may be important for microbiologic cure of select pathogens. Factors other than adherence should be considered for CT-negative men with persistent NGU.

    On 07 October 1998 a helicopter radiometric survey was flown in the vicinity of Krageroe municipality. The purpose of the survey was to provide radiometric information to help assess radon hazard from radioactive rocks in the area. A total of 60 line-kilometres of radiometric data were acquired in a single flight, covering an area of approximately 3 square km with a 50-m line spacing. The data were collected by Geological Survey of Norway (NGU) personnel and processed at NGU. Radiometric data were reduced using the three-channel procedure recommended by the International Atomic Energy Association. All data were gridded using square cells with 30-m sides and geophysical maps were produced at a scale of 1:5000. This report covers aspects of data acquisition and processing (Author)

    Azithromycin or doxycycline is recommended for nongonococcal urethritis (NGU); recent evidence suggests their efficacy has declined. We compared azithromycin and doxycycline in men with NGU, hypothesizing that azithromycin was more effective than doxycycline. From January 2007 to July 2011, English-speaking males ≥16 years, attending a sexually transmitted diseases clinic in Seattle, Washington, with NGU (visible urethral discharge or ≥5 polymorphonuclear leukocytes per high-power field [PMNs/HPF]) were eligible for this double-blind, parallel-group superiority trial. Participants received active azithromycin (1 g) + placebo doxycycline or active doxycycline (100 mg twice daily for 7 days) + placebo azithromycin. Urine was tested for Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Ureaplasma urealyticum biovar 2 (UU-2), and Trichomonas vaginalis (TV) using nucleic acid amplification tests. Clinical cure (urethral symptoms and absence of discharge) and microbiologic cure (negative tests for CT, MG, and/or UU-2) were determined after 3 weeks. Of 606 men, 304 were randomized to azithromycin and 302 to doxycycline; CT, MG, TV, and UU-2 were detected in 24%, 13%, 2%, and 23%, respectively. In modified intent-to-treat analyses, 172 of 216 (80%; 95% confidence interval [CI], 74%-85%) receiving azithromycin and 157 of 206 (76%; 95% CI, 70%-82%) receiving doxycycline experienced clinical cure (P = .40). In pathogen-specific analyses, clinical cure did not differ by arm, nor did microbiologic cure differ for CT (86% vs 90%, P = .56), MG (40% vs 30%, P = .41), or UU-2 (75% vs 70%, P = .50). No unexpected adverse events occurred. Clinical and microbiologic cure rates for NGU were somewhat low and there was no significant difference between azithromycin and doxycycline. Mycoplasma genitalium treatment failure was extremely common. Clinical Trials Registration.NCT00358462.

    Background Nongonococcal urethritis (NGU) is common, yet up to 50% of cases have no defined etiology. The extent to which risk profiles and clinical presentations of pathogen-associated and idiopathic cases differ is largely unknown. Methods Urethral swabs and urine specimens were collected from 370 NGU treatment trial participants who sought care at a sexually transmitted disease clinic in Seattle, WA from 2007 to 2009 and had a visible urethral discharge and/or microscopic evidence of urethral inflammation assessed by Gram-stain (≥5 polymorphonuclear leukocytes per high-powered field [PMNs/HPF]). Neisseria gonorrhoeae, Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Trichomonas vaginalis (TV), and Ureaplasma urealyticum (UU) were detected in urine, using nucleic acid amplification tests. Cases negative for all assessed pathogens were considered idiopathic. Bivariate and multivariate analyses identified clinical, sociodemographic, and behavioral factors associated with detection of specific pathogens. Results After excluding 3 participants with gonococcal infection, pathogens were detected in only 50.7% of the 367 eligible cases: CT in 22.3%, MG in 12.5%, TV in 2.5%, and UU in 24.0%, with multiple pathogens detected in 9.5%. In all, 3.5% of cases were negative for CT, MG, and TV but lacked speciated ureaplasma results. The remaining cases (45.8%) were considered idiopathic. Pathogen detection was associated with young age, black race, risky sexual behaviors, cloudy or purulent discharge, and visible discharge plus ≥5 PMNs/HPF. In contrast, idiopathic cases were more likely to report prior NGU, were older and less likely to be black, or have an abnormal urethral discharge on examination, compared to all other cases. These cases were not associated with any high risk behaviors. Conclusions NGU is a heterogeneous condition. Pathogen detection was associated with a variety of traditional risk factors and clinical features; whereas, idiopathic cases tended

    Objectives Mycoplasma genitalium and Chlamydia trachomatis are the primary pathogens detected from non-gonococcal urethritis (NGU). In this study, the efficacy of gatifloxacin was examined against M genitalium-related urethritis. Methods The study was an open clinical trial evaluating the effectiveness of gatifloxacin with 200 mg doses twice a day for 7 days against male NGU. Results Between March and September 2008, 169 male patients were enrolled, and microbiological and clinical cure rates could be evaluated in 86 patients detected with C trachomatis or M genitalium and in 135 with NGU, respectively. Microbiological cure rates of gatifloxacin against C trachomatis and M genitalium were 100% and 83%, respectively, and the total clinical cure rate was 99%. Conclusion Analysis of in-vivo and in-vitro data from the literature of fluoroquinolone efficacies against M genitalium suggests that a MIC90 of 0.125 μg/ml or less may be useful for optimal activity against M genitalium infection.

    Objective: To study the prevalence of Trichomonas vaginalis(TV) infection in Chinese male patients with nongonococcalurethritis (NGU), to evaluate the sensitivity and specificity ofurine-based and urethral swab polymerase chain reaction(PCR) detection, to set up a method for non-invasive detectionof male TV infection. Method: One hundred and five male NGU patients wereselected from a Beijing STD clinic. Two urethral swabs wereobtained from each patient, one for the InPouch TV culturesystem and the other for PCR. In addition, one first void urinespecimen was collected for PCR detection. Culture wasconsidered the "gold standard". The sensitivity, specificity,positive predictive value (PPV) and negative predictive value(NPV) of the two PCR detections were compared to cultureresults. Results: The prevalence of urine-based PCR and urethralswab PCR detection was 3.81% (4/105) and 4.76% (5/105)respectively. Compared to culture, the sensitivity, specificity,PPV and NPV were 80%, 100%, 100% and 99% for urine-based PCR and 80%, 99%, 80% and 99% for urethral swabPCR.Conclusion: TV is one of the etiological agents in male NGU,with a 4.76% prevalence of infection in our study. The urine-based PCR detection has higher sensitivity and specificity andprovides a noninvasive method more feasible in practice.

    Full Text Available Background/Aim. Non-gonococcal urethritis (NGU is a very common sexually transmitted disease. The etiology of the disease is complex and not completely solved. The aim of this study was to determine the bacteriological finding in the urethra in men with and without non-gonococcal utethritis. Methods. The study group comprised 200 men with symptoms of urethritis. The control group consisted of 60 men without symptoms of urethritis. The diagnosis of nongonococcal infection was made by finding of an increased number of polymorphonuclear leukocytes (≥ 5 under the microscope in a sample of Gram-stain of urethral smear (× 1 000 and without evidence of Neisseria. gonorrhoeae in specimens (negative direct microscopy and cell culture. Bacteriological examination included: direct microscopy with the Gramstained and methylblue-stained smears of urethral discharges, and cultivation of specimens under the aerobic/unaerobic conditions. In addition to standard bacterial examination and performinig direct imunofluorescence test to detect Chlamydia trachomatis (bioMerieux, France, urethral smears were also examined for the presence of Ureaplasma urealyticum and Mycoplasma hominis by commercially available Mycofast Evolution 2 test (International Microbio, France. The finding of mycoplasmas ≥ 104 CCU/ml was positive. The data were statistically analyzed using Pearson χ2 and Student t test. Results. C. trachomatis was predominant bacterial species found in urethra in men with nongonococcal urethritis. It was isolated alone and/or mixed with mycoplasmas and/or other bacteria in 86 (43.0% of examinees. There was statistically significant difference in finding of C. trachomatis between the study group and the control group (p < 0.001. U. urealyticum was found in men with NGU: 30.2% were with C. trachomatis and 36.0% were without C. trachomatis (p > 0.05.

    The aim of the study was to estimate the diagnostic and treatment patterns in the management of acute nongonococcal urethritis (NGU) in males in some cities of Russia. Retrospective cross-sectional study was conducted in 2009 in 5 centers of 4 cities in the Central Part of Russia (Kaluga, Pskov, Smolensk - 2 centres and Tula). The data on the diagnostic and treatment approaches to the management of NGU in male subjects >16 years old were collected and analyzed with the use of specially designed case report forms. 556 cases of acute urethritis were analyzed during the study. The diagnosis of NGU was confirmed in 401 cases. The average age of the patients was 29.8 years (16-68 years). The following diagnostic methods were used in 95% of the cases: urethral smear microscopy (314/82.4%), C. trachomatis - PCR (113/29.7%), ELISA (155/40.7%); T. vaginalis - PCR (106/27.8%); U. urealyricum and M. hominis, respectively - bacteriology (140/36.7% and 126/33.1%), PCR (110/28.9% and 108/28.3%); M. genitalium - PCR (110/28.9%). The treatment patterns included antimicrobials AMs alone in 60.3, and AMs + non-AMs in 37.8% of the cases. The most frequently prescribed AMs were azithromycin (27.5%), fluconazole (16.4%), doxycycline (13.6%), metronidazole (11.2%), ofloxacine (7.3%), ceftriaxone (4.4%), josamycin (4.2). According to the results use of the standard methods for NGU diagnosis was rather rare. The use of PCR for atypical pathogens was the following: C. trachomatis 29.7%, U. urealyticum 36.7%, M. hominis 28.9%, M. genitalium 28.3%. Doubtful culture methods were used for detection of U. urealyticum and M. hominis (36.7% and 33.1%). The AMs treatment in some cases was not in compliance with the up-to-date practical guidelines for STD and NGU.

    We isolated a cryptic genospecies of Haemophilus influenzae referred to as 'Haemophilus quentini' in the urethra of 3 men complaining of urethritis symptoms. H. influenzae strains, which had been isolated from the urethra in 77 of 1518 men complaining of urethritis symptoms, identified by the conventional test, and stored, were re-cultured for this study. Sixty-seven strains surviving storage were screened by a PCR-based assay specific for the cryptic genital Haemophilus genospecies. Three strains (HI09003, HI11006, and HI14016) were screened by PCR and identified as 'H. quentini' by 16S rRNA sequencing. The men positive for HI09003 and HI11006 were diagnosed as having non-chlamydial non-gonococcal urethritis (NGU), and their demographic and clinical features were similar to those of NGU caused by other pathogens. The man positive for HI14016 was ultimately diagnosed as having condyloma acuminatum on the glans. The 3 strains of 'H. quentini' produced no β-lactamase and were susceptible to ampicillin and other antimicrobial agents, including cephalosporins, fluoroquinolones, tetracyclines, and macrolides, recommended for treatment for urethritis. 'H. quentini' would be an uncommon pathogen in men with urogenital infections. Based on the clinical features of the two patients with 'H. quentini'-positive NGU, it would be difficult to predict the presence of 'H. quentini' in the urethra. The 3 strains of 'H. quentini' were susceptible to a variety of antimicrobial agents. Further accumulation of data regarding 'H. quentini' infections is needed to characterize the pathogenic roles of this genospecies in urogenital infections and to establish appropriate management of 'H. quentini' infections.

    Objective U. urealyticum biovar 2 (UU-2) but not U. parvum (UP) has been associated with non-gonococcal urethritis (NGU), but little is known about species-specific responses to standard therapies. We examined species-specific treatment outcomes and followed men with treatment failure for 9 weeks. Methods From May 2007-July 2011, men aged ≥16 attending an STD clinic in Seattle, Washington with NGU (urethral discharge or urethral symptoms plus ≥5 PMNs/HPF) were enrolled in a double-blind, randomized trial. Participants received active azithromycin (1g) + placebo doxycycline or active doxycycline (100mg bid × 7d) + placebo azithromycin. Ureaplasmas were detected in culture followed by species-specific PCR. Outcomes were assessed at 3, 6, and 9 weeks. At 3 weeks, men with persistent Ureaplasmas received “reverse therapy” (e.g., active doxycycline if they first received active azithromycin). At 6 weeks, persistently-positive men received moxifloxacin (400mg × 7d). Results Of 490 men, 107 (22%) and 60 (12%) were infected with UU-2 and UP, respectively, and returned at 3 weeks. Persistent infection was similar for UU-2-infected men initially treated with azithromycin or doxycycline (25% vs. 31%, P=0.53), but differed somewhat for men with UP (45% vs. 24%; P=0.11). At 6 weeks, 57% of UU-2-infected and 63% of UP-infected men who received both drugs had persistent infection. Failure after moxifloxacin occurred in 30% and 36%, respectively. Persistent detection of UU-2 or UP was not associated with signs/symptoms of NGU. Conclusion Persistent infection after treatment with doxycycline, azithromycin, and moxifloxacin was common for UU and UP, but not associated with persistent urethritis. PMID:25616607

    The advanced modified high performance synthetic jet actuator with optimized curvature shape chamber (ASJA-M) is a synthetic jet actuator (SJA) with a lower volume reservoir or chamber. A curved chamber is used, instead of the conventional cylinder chamber, to reduce the dead volume of the jet chamber and increase the efficiency of the synthetic jet actuator. The shape of the curvature corresponds to the maximum displacement (deformation) profile of the electroactive diaphragm. The jet velocity and mass flow rate for the ASJA-M will be several times higher than conventional piezoelectric actuators.

  11. GammaLog Playback 1.0 - mobile gamma ray spectrometry software

    Watson, R.J.; Smethurst, M.A.

    2011-01-01

    The Geological Survey of Norway (NGU) operates a mobile gamma ray spectrometer system which can be used in nuclear emergency situations to determine the location and type of orphan sources, or the extent and type of fallout contamination. The system consists of a 20 litre (16 litre downward and 4 litre upward looking) RSX-5 NaI detector and spectrometer, and can be mounted in fixed wing aircraft, helicopters, or vans/cars as appropriate. NGU has developed its own data acquisition and analysis software for this system. GammaLog (Smethurst 2005) controls the acquisition, display, and storage of data from the spectrometer, and performs real-time data analysis including estimation of dose rates and fallout concentrations, and separation of geological and anthropogenic components of the signal. The latter is particularly important where the geological radioisotope signal varies strongly from one place to another, and makes it easier to locate and identify anthropogenic sources which might otherwise be difficult to separate from the geological background signal. A modified version of GammaLog has been developed, GammaLog Playback, which allows the replay of previously acquired GammaLog datasets, while performing similar processing and display as the GammaLog acquisition software. This allows datasets to be reviewed and compared in the field or during post-survey analysis to help plan subsequent measurement strategies.(Au)

    Schistosomiasis is an infectious disease caused by parasites of the phylum platyhelminthe. Here, we describe the identification and characterization of a Bcl-2-regulated apoptosis pathway in Schistosoma japonicum and S. mansoni. Genomic, biochemical, and cell-based mechanistic studies provide evidence for a tripartite pathway, similar to that in humans including BH3-only proteins that are inhibited by prosurvival Bcl-2-like molecules, and Bax/Bak-like proteins that facilitate mitochondrial outer-membrane permeabilization. Because Bcl-2 proteins have been successfully targeted with "BH3 mimetic" drugs, particularly in the treatment of cancer, we investigated whether schistosome apoptosis pathways could provide targets for future antischistosomal drug discovery efforts. Accordingly, we showed that a schistosome prosurvival protein, sjA, binds ABT-737, a well-characterized BH3 mimetic. A crystal structure of sjA bound to a BH3 peptide provides direct evidence for the feasibility of developing BH3 mimetics to target Bcl-2 prosurvival proteins in schistosomes, suggesting an alternative application for this class of drugs beyond cancer treatment.

Genomic, biochemical, and cell-based mechanistic studies provide evidence for a tripartite pathway, similar to that in humans including BH3-only proteins that are inhibited by prosurvival Bcl-2–like molecules, and Bax/Bak-like proteins that facilitate mitochondrial outer-membrane permeabilization. Because Bcl-2 proteins have been successfully targeted with “BH3 mimetic” drugs, particularly in the treatment of cancer, we investigated whether schistosome apoptosis pathways could provide targets for future antischistosomal drug discovery efforts. Accordingly, we showed that a schistosome prosurvival protein, sjA, binds ABT-737, a well-characterized BH3 mimetic. A crystal structure of sjA bound to a BH3 peptide provides direct evidence for the feasibility of developing BH3 mimetics to target Bcl-2 prosurvival proteins in schistosomes, suggesting an alternative application for this class of drugs beyond cancer treatment.

    Full Text Available Calcium-activated nonlysosomal neutral proteases, calpains, are believed to be early mediators of neuronal damage associated with neuron death and axonal degeneration after traumatic neural injuries. In this study, a library of biologically active small molecular weight calpain inhibitors was used for model validation and inhibition site recognition. Subsequently, two natural neuroactive polyphenols, curcumin and quercetin, were tested for their sensitivity and activity towards calpain’s proteolytic sequence and compared with the known calpain inhibitors via detailed molecular mechanics (MM, molecular dynamics (MD, and docking simulations. The MM and MD energy profiles (SJA6017 < AK275 < AK295 < PD151746 < quercetin < leupeptin < PD150606 < curcumin < ALLN < ALLM < MDL-28170 < calpeptin and the docking analysis (AK275 < AK295 < PD151746 < ALLN < PD150606 < curcumin < leupeptin < quercetin < calpeptin < SJA6017 < MDL-28170 < ALLM demonstrated that polyphenols conferred comparable calpain inhibition profiling. The modeling paradigm used in this study provides the first detailed account of corroboration of enzyme inhibition efficacy of calpain inhibitors and the respective calpain–calpain inhibitor molecular complexes’ energetic landscape and in addition stimulates the polyphenol bioactive paradigm for post-SCI intervention with implications reaching to experimental in vitro, in cyto, and in vivo studies.

    Ureaplasma urealyticum biovar 2 (UU-2), but not Ureaplasma parvum (UP), has been associated with non-gonococcal urethritis (NGU), but little is known about species-specific responses to standard therapies. We examined species-specific treatment outcomes and followed men with treatment failure for 9 weeks. From May 2007 to July 2011, men aged ≥16 attending a sexually transmitted disease (STD) clinic in Seattle, Washington, with NGU (urethral discharge or urethral symptoms plus ≥5 polymorphonuclear leucocytes /high-powered field) enrolled in a double-blind, randomised trial. Participants received active azithromycin (1 g) + placebo doxycycline or active doxycycline (100 mg twice a day ×7 days) + placebo azithromycin. Ureaplasma were detected in culture followed by species-specific PCR. Outcomes were assessed at 3, 6 and 9 weeks. At 3 weeks, men with persistent Ureaplasma detection received 'reverse therapy' (e.g., active doxycycline if they first received active azithromycin). At 6 weeks, persistently positive men received moxifloxacin (400 mg×7 days). Of 490 men, 107 (22%) and 60 (12%) were infected with UU-2 and UP, respectively, and returned at 3 weeks. Persistent detection was similar for UU-2-infected men initially treated with azithromycin or doxycycline (25% vs. 31%; p=0.53), but differed somewhat for men with UP (45% vs. 24%; p=0.11). At 6 weeks, 57% of UU-2-infected and 63% of UP-infected men who received both drugs had persistent detection. Failure after moxifloxacin occurred in 30% and 36%, respectively. Persistent detection of UU-2 or UP was not associated with signs/symptoms of NGU. Persistent detection after treatment with doxycycline, azithromycin and moxifloxacin was common for UU and UP, but not associated with persistent urethritis. NCT00358462.

    Of 73 clinical strains of Haemophilus influenzae isolated from the urethra of men with urogenital infections, we enrolled 6 strains (8.2%) with levofloxacin (LVFX) minimum inhibitory concentrations (MICs) of ≥0.03 μg/ml in this study. All the strains were isolated from non-gonococcal urethritis (NGU). We amplified the quinolone resistance-determining region of the gyrA gene and the analogous region of the parC gene from bacterial DNAs by PCR and sequenced the PCR products. Two strains with a LVFX MIC of 0.03 μg/ml had an amino acid change of Asp88 to Gly in GyrA. One with a LVFX MIC of 0.06 μg/ml had a change of Asp88 to Tyr in GyrA. Two with respective LVFX MICs of 0.12 and 0.25 μg/ml had a change of Ser84 to Leu in GyrA. One with a LVFX MIC of 1 μg/ml had changes of Ser84 to Leu in GyrA and of Ser84 to Ile in ParC. Multilocus sequence typing showed two strains with a change of Asp88 to Gly in GyrA had the same sequence type, but the others had sequence types different from each other. Single amino acid changes in GyrA alone or single changes in both GyrA and ParC could contribute to decreased susceptibility to fluoroquinolones in H. influenzae isolates from NGU. Most of the isolates with GyrA and/or ParC alterations would be multiclonal. The prevalence of such isolates would be relatively low, and they would still be susceptible to fluoroquinolones commonly prescribed for treatment of NGU.

    Objective: To assess whether syndromic management of genital ulcer disease was sound, if based on the premise that men with genital ulcers rarely have a concomitant urethral infection. Methods: Specimens were taken in 1998 from 186 mine workers in Carletonville, South Africa, who were seen consecutively with genital ulcers. The specimens comprised a swab from the ulcer, a urethral swab for a Gram stained smear, and 10–15 ml of a first catch urine sample. The latter was tested by ligase chain reaction assays for Neisseria gonorrhoeae and Chlamydia trachomatis specific DNA sequences and by a polymerase chain reaction (PCR) assay for Mycoplasma genitalium. Ulcer inducing micro-organisms were detected either by a multiplex PCR assay, or in the case of lymphogranuloma venereum (LGV) serologically, and human immunodeficiency virus (HIV) infection was detected by an enzyme linked immunosorbent assay (ELISA) test. Results: Most (54%) of the ulcers were chancroidal, 18% were herpetic (HSV type 2), 6.5% primary syphilitic, and 3.2% due to LGV. More than one micro-organism was detected in 9.1% of the ulcers and less than 10% were undiagnosed. Microscopic examination of the urethral smears showed that 99 (53%) of the men had urethritis, of whom 45 (45%) were infected with N gonorrhoeae. Of the 54 men (55%) who had non-gonococcal urethritis (NGU), 11 (19.6%) harboured C trachomatis or M genitalium. Almost two thirds (64.5%) of the men had HIV infection, but this did not seem to have influenced the aetiology of the ulcers. Nor was a particular ulcer associated with one type of urethritis more than the other. Neither C trachomatis nor M genitalium was associated significantly with non-gonococcal urethritis (NGU) in either HIV positive or HIV negative men. Conclusion: The combination of antibiotics used for the management of genital ulcer disease in men in this South African mining population needs to be widened to encompass frequently occurring concomitant gonococcal urethritis

    Full Text Available A total of 4129 patients attended the STD clinic from 1996 to 1999. Of those 25.75% were STD cases. Male and female cases comprised 86% and 14% respectively. Majority were in the age group between 18 to 38 years. Choncroid was the commonest STD (37. 7%. Other STDs in order were syphilis (30. 66%, NGU (15.71%, gonorrhoea (7%, venereal wart (3.57%, candidiasis (2.53%, trichomonal vaginitis (1.6%, herpes genitalis (0.65% and LGV (0.47%. No case of Donovanosis or HIV was detected. 13.7% of STD cases were reactive for VDRL test and 8% of the antenatal attendents were strongly VDRL test reactive. The urethral discharge on gram staining was positive for gonococcus, in 29%. 68% of the clinic attendents were given safer sex education and served condom.

    The primary outcome was to determine the acceptability of the Internet, specifically a website for use in standard partner notification. A secondary objective was to determine if a website would enhance the outcomes of currently used partner notification methods. In a randomized control trial, 105 participants diagnosed with chlamydia and non-gonoccocal urethritis (NGU) were randomized and 97 completed the study. About 30% of participants were provided a standard partner letter and 70% were provided the standard partner letter and website. All participants reported that their partners had no objections to the website (0%, 95% confidence interval [CI] 0-5%). There were no complaints received from any partner. The odds ratio for contacting partners was not significantly different between the two groups of participants. The results of this study indicate that providing a website with specific information about the infection to which a partner has been exposed is not harmful.

    Objectives Gram-stained urethral smear (GSUS), the standard point-of-care test for non-gonococcal urethritis (NGU) is operator dependent and poorly specific. The performance of rapid automated urine flow cytometry (AUFC) of first void urine (FVU) white cell counts (UWCC) for predicting Mycoplasma genitalium and Chlamydia trachomatis urethral infections was assessed and its application to asymptomatic infection was evaluated. Methods Receiver operating characteristic curve analysis, determining FVU-UWCC threshold for predicting M. genitalium or C. trachomatis infection was performed on 208 ‘training’ samples from symptomatic patients and subsequently validated using 228 additional FVUs obtained from prospective unselected patients. Results An optimal diagnostic threshold of >29 UWC/µL gave sensitivities and specificities for either infection of 81.5% (95% CI 65.1% to 91.6%) and 85.8% (79.5% to 90.4%), respectively, compared with 86.8% (71.1% to 95%) and 64.7% (56.9% to 71.7%), respectively, for GSUS, using the training set samples. FVU-UWCC demonstrated sensitivities and specificities of 69.2% (95% CI 48.1% to 84.9%) and 92% (87.2% to 95.2%), respectively, when using validation samples. In asymptomatic patients where GSUS was not used, AUFC would have enabled more infections to be detected compared with clinical considerations only (71.4% vs 28.6%; p=0.03). The correlation between UWCC and bacterial load was stronger for M. genitalium compared with C. trachomatis (τ=0.426, p≤0.001 vs τ=0.295, p=0.022, respectively). Conclusions AUFC offers improved specificity over microscopy for predicting C. trachomatis or M. genitalium infection. Universal AUFC may enable non-invasive diagnosis of asymptomatic NGU at the PoC. The degree of urethral inflammation exhibits a stronger association with pathogen load for M. genitalium compared with C. trachomatis. PMID:25614466

    Urethral swabs are the samples of choice for point-of-care Gram stain testing to diagnose Neisseria gonorrhoeae infection and nongonococcal urethritis (NGU) in men. As an alternative to urethral swabs, meatal swabs have been recommended for the collection of urethral discharge to diagnose N. gonorrhoeae and Chlamydia trachomatis infection in certain populations by nucleic acid amplification testing (NAAT), as they involve a less invasive collection method. However, as meatal swabs could be sampling a reduced surface area and result in fewer collected epithelial cells compared to urethral swabs, the adequacy of meatal swab specimens to collect sufficient cellular material for Gram stain testing remains unknown. We enrolled 66 men who underwent either urethral or meatal swabbing and compared the cellular content and Gram stain failure rate. We measured the difference in swab cellular content using the Cepheid Xpert CT/NG sample adequacy control crossing threshold (SAC CT ) and determined the failure rate of Gram stain smears (GSS) due to insufficient cellular material. In the absence of discharge, meatal smears were associated with a significant reduction in cellular content ( P = 0.0118), which corresponded with a GSS failure rate significantly higher than that for urethral swabs (45% versus 3%, respectively; P < 0.0001). When discharge was present, there was no difference among results from urethral and meatal swabs. Therefore, if GSS testing is being considered for point-of-care diagnosis of N. gonorrhoeae infection or NGU in men, meatal swabs should be avoided in the absence of a visible discharge.

    The impact of Adenovirus as agent of non-gonococcal urethritis (NGU) is still poorly documented in the literature. We describe two cases showing that adenoviral infection should be reasonably hypothesized in men with dysuria and scant urethral discharge in addition to meatus inflammation and/or edema (meatitis) or conjunctivitis. Case 1: a 55-year-old man came to our observation in July 2012 referring a 5-day-history of intense dysuria and scant mucoid urethral discharge. Physical examination revealed the urethral discharge referred, but also modest meatitis and an intense conjunctival hyperemia on his right eye. Adenoviral infection was investigated and Adenovirus DNA (type 37) was detected in both the urethral and conjunctival swabs. Case 2: a 43-year-old man with intense dysuria, started 4-5 days earlier, came to our attention with his wife in August 2012. Scant urethral mucoid secretions, severe meatal inflammation of the male patient were revealed during physical examination. His wife instead complained of a 2-day history of intense burning eyes. Adenoviral infection was investigated and Adenovirus DNA (type 37) was positive both in the male urethral swab and in his wife's conjunctival swab. Adenovirus seems to cause a distinct and recognisable clinical syndrome in men presenting with urethritis. Studies on the prevalence and role of Adenovirus as a causative agent of urethritis are limited. Moreover, as rapid advanced molecular microbiology is now available, we believe that extending the search to Adenovirus in sexually active men with dysuria, scant discharge in addition to meatitis or conjunctivitis, should be a useful approach improving our understanding about adenoviral NGU, and especially avoiding or stopping unnecessary empirical antibiotic therapy.

    Pineapple production in Costa Rica increased nearly 300-fold during the last 30 yr, and >40,000 hectares of land are currently dedicated to this crop. At the end of the pineapple cropping cycle, plants are chopped and residues incorporated into the soil in preparation for replanting. Associated with increased pineapple production has been a large increase in stable fly, Stomoxys calcitrans (L.), populations. Stable flies are attracted to, and oviposit in, the decomposing, chopped pineapple residues. In conjunction with chemical control of developing larvae, adult trapping is an important control strategy. In this study, four blue-black fabric traps, Nzi, Vavoua, Model H, and Ngu, were compared with a white sticky trap currently used for stable fly control in Costa Rica. Overall, the white sticky trap caught the highest number of stable flies, followed by the Nzi, Vavoua, Model H, and Ngu. Collections on the white sticky trap increased 16 d after residues were chopped; coinciding with the expected emergence of flies developing in the pineapple residues. During this same time period, collections in the blue-black fabric traps decreased. Sex ratio decreased from >7:1 (females:males) 3-7 d after chopping to 1:1 at 24-28 d. White sticky, Nzi and Vavoua traps collected similar numbers of colonizing flies 3-7 d after residues were chopped. However, white sticky traps collected more flies once emergence from the pineapple residues began. Although white sticky traps collected more flies than fabric traps, they remain labor intensive and environmentally unsound because of their disposable and nonbiodegradable nature.

    Valve-related complications after Björk-Shiley mitral (n = 475), aortic (n = 424), or mitral-aortic implantation (n = 119) were compared to complications after St. Jude mitral (n = 173), aortic (n = 152), and St. Jude mitral and aortic (n = 63) replacements. The 1,018 consecutive patients with Björk-Shiley valves had been operated upon between 1974 and 1982, those with St. Jude valves between 1978 and 1982. All patients were placed on anticoagulant therapy with phenprocoumon early after operation and no significant intergroup differences in the effectiveness of the anticoagulant therapy were found. At a comparable follow-up time of approximately 23 months, 24 major thromboembolic episodes were observed after Björk-Shiley mitral (BSM) and 3 after St. Jude mitral valve implantation (SJM), corresponding to a thromboembolic rate of 2.82/100 patient years with BSM and 0.93/100 patient years with SJM. After aortic valve replacements, 1.93 events in 100 patient years occurred after Björk-Shiley aortic (BSA) and 0.73 after St. Jude aortic implantation (SJA). In patients with double valve replacements, these rates were 3.2 (BSM + BSA) and 0.88 (SJM + SJA), respectively. The cerebral vessels were involved in 52% and the arteries of the extremities in 22% of these major events. Six Björk-Shiley prostheses had to be replaced because of valve thrombosis. The overall incidence of severe hemorrhagic complications was 2.94/100 patient years in BSM and 1.79 in SJM. After aortic valve replacement, we found rates of 1.80/100 patient years (BSA) and 2.57/100 patient years (SJA), respectively. Intravascular hemolysis no longer seems to be a significant clinical problem. However, indications of red cell damage after heart valve replacement were significantly greater in patients with perivalvular leakage, valve thrombosis, or dysfunction than in those with normally functioning prostheses. Reoperations were necessary because of valve thrombosis (0.46%), perivalvular leakage (2

    The purpose of this study was to test the feasibility of applying AVIRIS sensor (Airborne Visible/Infra Red Imaging Spectrometer) for mapping and quantifying mineralogical components of three Brazilian soils, a reddish Oxisol in Sao Joao D'Alianca area (SJA) and a dark reddish brown Oxisol and Ultisol in Niquelandia (NIQ) counties, Goias State. The study applied the spectral index RCGb [kaolinite/(kaolinite + gibbsite) ratio] and was based on spectral absorption features of these two minerals.The RCGb index was developed for the evaluation of weathering degrees of various Brazilian soils and was validated by the analysis of soil samples spectra imaged by AVIRIS and checked against laboratory mineralogical quantification (TGA:Thermal Gravimetric Analysis). Results showed to be possible mapping and quantifying the weathering degree of the studied soils and that the two selected areas presented different weathering degrees of their soils even for a same soil type.

    2015-01-01

    Full Text Available The aim of this paper is the modeling of the stress demagnetization effect on the magnetic properties in a non-oriented Fe-Si 3% sheet under different external stresses. The magneto-mechanical model used for magnetic hysteresis is based on a model originally formulated by Sablik-Jiles-Atherthon (S.J.A.. This latter has been modified by including both the stress demagnetization factor and the eddy current effects. The influence of the stress demagnetization term SDT on the magnetostrictive behavior of the material is also modeled. The proposed model has been validated by extensive simulations at different stresses, namely compressive and tensile stresses. Simulation results obtained by this model are very close to those published in the literature. Using the proposed model, very satisfactory performance has been achieved.

    The authors discuss present-day ideas concerning precursor cells in lymphoid tissues and suggest that the stem cells' decision in regard to proliferation and the path of further differentiation may be a multi-stage process, occurring at various successive phases in the histogenesis of lymphoid cells. They propose that only those elements which are capable of actively deciding (under the influence of suitable stimuli or factors inherent in the cell) in which direction the successor cells are to differentiate should be regarded as precursor cells. It is shown that there are in lymphoid tissue at least three stages with the properties of precursor cells: the stem haemopoietic cell, the antigen-sensitive cell and the immunological memory cell. The authors suggest that the working cells of immune response are transformed into immunological memory cells, and discuss the morphological characteristics of the precursor cells.

    Full Text Available Mitmed üliõpilaste seas läbi viidud uuringud näitavad seost epistemoloogiliste uskumuste ehk teadmuskäsituse ja õpikäsituse vahel. Need uskumused ise aga tingivad selle, kuidas üliõpilased võtavad vastu erinevaid õppejõu tegevusi ja kuidas nad õpivad. Viimasel ajal levivad ka Eestis üha enam aktiivõppe meetodid, mis eeldavad üliõpilastelt teistsugust valmisolekut kui passiivne loengu vormis õppimine. Käesoleva töö eesmärk oligi kirjeldada, millised on Eesti esimese kursuse üliõpilaste epistemoloogilised uskumused ja õpikäsitus ning kuidas need mõjutavad üliõpilaste õpieelistusi. Lähtuti hüpoteesist, et Eesti esmakursuslased on pigem passiivsed, fikseeritud laadi epistemoloogiliste uskumustega ning ootavad õppejõult kui autoriteedilt nn valmisteadmisi. Seetõttu eelistavad nad töötada pigem üksi, mitte rühmas.Uurimuse hüpotees leidis üldjoontes kinnitust. Enamik uuritud esimese kursuse üliõpilastest käsitab teadmist oskuse või kogemusena. Õppimine on uute teadmiste omandamine õppejõult, kaaslastel on eelkõige vaid motiveeriv roll. Esmakursuslased eelistavad õppejõudu, kes on autoriteet ja ekspert, mistõttu oodatakse, et õppejõud tooks elulisi näiteid ja selgitaks õpitavat samm-sammult. Suur osa küsimustiku täitnud üliõpilastest on pindmise õpihoiakuga: nad mõistavad teadmist eelkõige fakti, kogemuse või oskusena ja eelistavad õppida üksi. Samal ajal on neil pluralistlikku laadi epistemoloogilised uskumused. Uuringust selgus ka, et sügava õpihoiakuga üliõpilased näevad õppimist protsessina ning teadmisi sealjuures ajas muutuvate ja arenevatena.Ainsaks kõrvalekaldeks esialgsest hüpoteesist olid üliõpilaste valdavalt pluralistlikud epistemoloogilised uskumused, mis võivad viidata ühiskonnas üldiselt levivale arusaamale, et pole ühtset tõde, vaid on palju tõlgendusi.

    The Norwegian Water Resources and Energy Directorate (NVE) in cooperation with the Geological Survey of Norway (NGU) are implementing a nationwide program to systematically produce hazard maps for rockfalls, debris flows and snow avalanches in steep terrains. Activities during this program mapping are being carried out by both institutions, and for some areas, outsourced to the private sector. The results presented in this contribution focus on the rockfall component only, and are part of the hazard mapping activities carried out by NGU. Results from all parties involved will further lead in future, in combination with the components on debris flows and snow avalanches, to the preparation of guidelines for landslide hazard mapping. Those will be presented and recommended for the use of private consultants that work on municipality level. The first goal of the project is the preparation of hazard maps for critical areas where a large number of people are exposed to the threat of such type of mass movements. Results from a pilot area in Sylte (Norddal municipality) were presented in the EGU general assembly in 2012. The main objective of this contribution is to present the first finished rockfall hazard maps generated by NGU during the execution of the program. The results presented in this contribution were obtained for the Norddal municipality (Møre og Romsdal county). The area was selected based on the hazard mapping plan of Norway published in 2011, where Norddal is considered a priority area. The area is located in a valley over-steepened by glacial erosion that is characterized by high cliffs of medium to coarse-grained quartz-dioritic to granitic gneisses of Proterozoic age. Multiple scree deposits product of older and recent rockfall activity can be seen along the bottom at both valley flanks. Sylte, the main locality in the Norddal municipality, is located at the valley outlet to the fjord. Several other smaller localities are found along the valley. A

    A large number of sparker lines were acquired on the Norwegian continental shelf during the years 1970-1982, by IKU (Sintef Petroleum Research). The responsibility of the analogue seismic database was transferred to NGU in 1998; this included storage of the physical data (original paper rolls and half-scale film copies) and the digital navigation database. The data (from 60°N to 71°30N) were in the early eighties subdivided in 6 data packages, and offered for sale to oil companies as half scale folded paper copies (25 cm width). Navigation applied was mainly Decca Main Chain. The 2014-2016 SPARDIG project (Chand et al., 2016) was supported by NGU, AkerBP (Det Norske), Lundin Norway and the Seabed Project. In the project, IPGS has transformed 374 rolls of analogue sparker lines in 17 different surveys into SEG-Y format. The total length of converted survey lines is 31 261 kilometers. Rolls were scanned at 600 dpi and converted into SEG-Y using the SeisTrans (Caldera software) application (Miles et al., 2007). SeisTrans uses interactive, iterative and repeatable steps in a dedicated graphics window. A first step allows definition of axes and scales, then record time lines (horizontal TWT times and navigation time lines down the record) are picked and removed, and traces are defined. At this step, control tools are available to ensure the quality of the traces. After that, navigation information extracted and interpolated from excel files are added to trace headers. A continuous QC process allows production of SEG-Y files directly readable by interpretation software. The SEG-Y data will be delivered to the Norwegian Discos National Repository (https://portal.diskos.cgg.com/whereoil-data/) but access will be restricted to participants until 1st April 2019. IKU sparker lines have higher resolution than conventional 2D lines, but the penetration is limited. The data sets are complementary to each other. In 2D seismic lines, it is often difficult to delineate units in

    Non-gonococcal urethritis (NGU), or inflammation of the urethra, is the most common treatable sexually transmitted syndrome in men, with approximately 20-50 % of cases being due to infection with Chlamydia trachomatis and 10-30 % Mycoplasma genitalium. Other causes are Ureaplasma urealyticum, Trichomonas vaginalis, anaerobes, Herpes simplex virus (HSV) and adenovirus. Up to half of the cases are non-specific. Urethritis is characterized by discharge, dysuria and/or urethral discomfort but may be asymptomatic. The diagnosis of urethritis is confirmed by demonstrating an excess of polymorpho-nuclear leucocytes (PMNLs) in a stained smear. An excess of mononuclear leucocytes in the smear indicates a viral etiology. In patients presenting with symptoms of urethritis, the diagnosis should be confirmed by microscopy of a stained smear, ruling out gonorrhea. Nucleid acid amplifications tests (NAAT) for Neisseria gonorrhoeae, C. trachomatis and for M. genitalium. If viral or protozoan aetiology is suspected, NAAT for HSV, adenovirus and T. vaginalis, if available. If marked symptoms and urethritis is confirmed, syndromic treatment should be given at the first appointment without waiting for the laboratory results. Treatment options are doxycycline 100 mg x 2 for one week or azithromycin 1 gram single dose or 1,5 gram distributed in five days. However, azithromycin as first line treatment without test of cure for M. genitalium and subsequent Moxifloxacin treatment of macrolide resistant strains will select and increase the macrolide resistant strains in the population. If positive for M. genitalium, test of cure samples should be collected no earlier than three weeks after start of treatment. If positive in test of cure, moxifloxacin 400 mg 7-14 days is indicated. Current partner(s) should be tested and treated with the same regimen. They should abstain from intercourse until both have completed treatment. Persistent or recurrent NGU must be confirmed with microscopy

    Gram-stained urethral smear (GSUS), the standard point-of-care test for non-gonococcal urethritis (NGU) is operator dependent and poorly specific. The performance of rapid automated urine flow cytometry (AUFC) of first void urine (FVU) white cell counts (UWCC) for predicting Mycoplasma genitalium and Chlamydia trachomatis urethral infections was assessed and its application to asymptomatic infection was evaluated. Receiver operating characteristic curve analysis, determining FVU-UWCC threshold for predicting M. genitalium or C. trachomatis infection was performed on 208 'training' samples from symptomatic patients and subsequently validated using 228 additional FVUs obtained from prospective unselected patients. An optimal diagnostic threshold of >29 UWC/µL gave sensitivities and specificities for either infection of 81.5% (95% CI 65.1% to 91.6%) and 85.8% (79.5% to 90.4%), respectively, compared with 86.8% (71.1% to 95%) and 64.7% (56.9% to 71.7%), respectively, for GSUS, using the training set samples. FVU-UWCC demonstrated sensitivities and specificities of 69.2% (95% CI 48.1% to 84.9%) and 92% (87.2% to 95.2%), respectively, when using validation samples. In asymptomatic patients where GSUS was not used, AUFC would have enabled more infections to be detected compared with clinical considerations only (71.4% vs 28.6%; p=0.03). The correlation between UWCC and bacterial load was stronger for M. genitalium compared with C. trachomatis (τ=0.426, p≤0.001 vs τ=0.295, p=0.022, respectively). AUFC offers improved specificity over microscopy for predicting C. trachomatis or M. genitalium infection. Universal AUFC may enable non-invasive diagnosis of asymptomatic NGU at the PoC. The degree of urethral inflammation exhibits a stronger association with pathogen load for M. genitalium compared with C. trachomatis. Published by the BMJ Publishing Group Limited.

    Background. Nongonococcal urethritis (NGU) is a common chlamydia-associated syndrome in men; however, Trichomonas vaginalis and Mycoplasma genitalium are associated with its etiology and should be considered in approaches to therapy. We sought to determine whether the addition of tinidazole, an anti-trichomonal agent, to the treatment regimen would result in higher cure rates than those achieved with treatment with doxycycline or azithromycin alone. A secondary aim was to compare the efficacy of doxycycline therapy and with that of azithromycin therapy. Methods. Randomized, controlled, double-blinded phase IIB trial of men with NGU. Participants were randomized to receive doxycycline plus or minus tinidazole or azithromycin plus or minus tinidazole and were observed for up to 45 days. Results. The prevalences of Chlamydia trachomatis, M. genitalium, and T. vaginalis were 43%, 31%, and 13%, respectively. No pathogens were identified in 29% of participants. Clinical cure rates at the first follow-up visit were 74.5% (111 of 149 patients) for doxycycline-containing regimens and 68.6% (107 of 156 patients) for azithromycin-containing regimens. By the final visit, cure rates were 49% (73 of 149 patients) for doxycycline-containing regimens and 43.6% (68 of 156 patients) for azithromycin-containing regimens. There were no significant differences in clinical response rates among the treatment arms. However, the chlamydia clearance rate was 94.8% (55 of 58 patients) for the doxycycline arm and 77.4% (41 of 53 patients) for the azithromycin arm (P = .011), and the M. genitalium clearance rate was 30.8% (12 of 39 patients) for the doxycycline arm and 66.7% (30 of 45 patients) for the azithromycin arm (P = .002). Conclusions. Addition of tinidazole to the treatment regimen did not result in higher cure rates but effectively eradicated trichomonas. Clinical cure rates were not significantly different between patients treated with doxycycline and those treated

    In connection with the project ''Environmental and community useful tunnels'' the Norwegian Geologic Survey (NGU) has made geologic and geophysical investigations along parts of the tunnel at the Grualia in the Lunner county. The purpose of the geologic studies was to map and investigate weakness zones in the rock foundations. The geophysical studies aimed at testing techniques that was in little use in preliminary studies for tunnel operations. The methods used have been optical inspection of drill holes, measurements of temperature and conductivity in the water and the measuring of the natural gamma radiation in the drill holes. The resistivity in the drill holes is also determined and test pumping with flow measurements is carried out in order to calculate the well water influx capacity. These methods may contribute to information about the rock condition (cracking, water influx). Previously the NGU has made 2D resistivity measurements at the ground in the tunnel in order to map the weakness zones. The results from the measurements in 6 wells show large variations in the rock qualities. The wells are drilled towards indicated weakness zones. Open water conducting cracks and sections with largely cracked rocks are detected in or in the proximity of the tunnel route. The weakness zone between the hornfels and the syenite west of the Langvatnet is largely cracked, has a large water conducting capacity and there are some unstable masses. Further east several open, water- conducting cracks are detected in the syenite. Furthest to the east in the route cracked and unstable rocks are found. Several of the holes are blocked by ravines which confirm the poor rock quality. In the particular areas problems are to be expected during the operation with respect to water influx and stability. Methodically the drill hole studies have shown great value for the follow up of the 2D resistivity measurements on the ground. The indicated weakness zones through the 2D have been

    To determine the etiology and frequency of different types of urethritis in adult males. A case series. The Dermatology Department of PNS Shifa Hospital, Karachi, from June 2004 to December 2007. One hundred male patients having complaints of urethral discharge and dysuria reporting in the skin OPD were included in the study. Patients who had received systemic treatment for their complaints and those who had other systemic infections were excluded. A detailed history including history of sexual contact was taken. Dermatological examination including examination of external genitalia was also performed. All these patients were subjected to complete physical examination, complete urine examination, urethral pus for gram staining and culture, endo-urethral swab with urethral loop for seeing Chlamydia antigen by fluorescent microscopy, cultures for ureaplasma and Wet mount specimen microscopy for trichomonas along with HIV (serum ELISA) test. Non-gonococcal urethritis was diagnosed on the presence of more than five polymorphonuclear leucocytes per high power field in at least five fields of Gram stained urethral smear, in the absence of Gram negative diplococci. The mean age was 29.2 + or - 5.8 years. Seventy (70%) cases were diagnosed as gonococcal urethritis and 30 (30%) cases as non-gonococcal urethritis (NGU). History of illicit sexual exposure was available in 25 (25%) patients. The interval period between initiation of symptoms and reporting of patient in gonococcal urethritis was 4 to 30 days (mean 12.8 days) and 4 days to 2 months (mean 20.7 days) in non-gonococcal urethritis. The patients with gonococcal urethritis presented with purulent discharge in 66 (84%) cases, and dysuria in 49 (70%) cases. In the NGU group, 25 (80%) cases had mucoid discharge and 18 (65%) had dysuria. in 70%, Neisseria gonorrhoeae was isolated, Chlamydia trachomatis in 16%, ureaplasma in 8%, and Trichomonas vaginalis in 4%. No organism could be detected in 2% cases. HIV test was

    I feel that the changes which have taken place in science in the last few years open up new possibilities, about which I should like to say a few words. In 1951 we began work on thermonuclear reactions in the confident belief that we would solve the problem with a rush and immediately. I was assigned the task of ensuring that our future thermonuclear reactor would not get too much out of hand. It was like the story of the man who wished to invent a perpetual motion machine and had taken out a patent on a method for keeping it under control. This attitude stemmed from the successes in developing ''explosive thermonuclear reactors'', a task which was achieved within a very short period of time, leaving physicists with the impression that they could do everything - and do it fast. However, experience soon showed that here we had a scientific rather than a technological problem and that it would be necessary to study in detail the physics of plasmas - which we have now been doing for over ten years.

    NGU conducted an airborne geophysical survey in Mo i Rana area in July 2012. This report describes and documents the aquisition, processing and visualization of recorded datasets. The geophysical survey results reported herein are 1414 line km. The Geotech Ltd. Hummingbird frequency domain system supplemented by optically pumped cesium magnetometer and 1024 channels RSX-5 spectrometer was used for data aquisition. The survey was flown with 100 m line spacing, line direction of 180 deg North-South (in the west) and 150 deg NorthWest-SouthEast (in the east) with the average speed 96 km/h. The average terrain clearance of the bird was 55 m. Collected data were processed by AR GeoConsulting using Geosoft Oasis Montaj software. Raw total magnetic field data were corrected for diurnal variation and levelled using standard micro levelling algorithm. EM data were filtered and levelled using both automated and manual levelling procedure. Apparent resistivity was calculated from in-phase and quadrature data for each of the five frequencies separately using a homogeneous half space model. Apparent resistivity dataset was levelled and filtered. Radiometric data were processed using standard procedures recommended by International Atomic Energy Association (IAEA). All data were gridded with the cell size of 25 m and presented as shaded relief maps at the scale of 1:25 000.(Author)

    As a consequence of the Chernobyl accident, several areas in Norway received radioactive fallout. One of these areas is the eastern part of Jotunheimen in central Norway. Immediately after the accident in 1986, the Geological Survey of Norway (NGU) performed airborne gamma-ray spectroscopy in central Norway. At that time, it was not possible to calculate reliable radionuclide concentrations, and the data were presented as total counts per second. Several man-made radionuclides were present in the initial fallout, but due to short half-lives, most of these have now disintegrated into stable isotopes. 137Cs, with a half-life of 11.000 days (∼ 30 years) is still present in the environment in significant quantities, leading to high radioactivity levels in meat from reindeer and sheep. To obtain a detailed map of the caesium fallout concentration in Jotunheimen, an airborne gamma-ray spectrometry (AGRS) survey was carried out, focusing on reindeer grazing areas. This project was a cooperation between Reindeer Husbandry Administration, Norwegian Radiation Protection Authority and the Geological Survey of Norway.(Au)

    We present the updated International Union against Sexually Transmitted Infections (IUSTI) guideline for the management of non-gonococcal urethritis in men. This guideline recommends confirmation of urethritis in symptomatic men before starting treatment. It does not recommend testing asymptomatic men for the presence of urethritis. All men with urethritis should be tested for Chlamydia trachomatis and Neisseria gonorrhoeae and ideally Mycoplasma genitalium using a nucleic acid amplification test (NAAT) as this is highly likely to improve clinical outcomes. If a NAAT is positive for gonorrhoea, a culture should be performed before treatment. In view of the increasing evidence that azithromycin 1 g may result in the development of antimicrobial resistance in M. genitalium, azithromycin 1 g is no longer recommended as first line therapy, which should be doxycycline 100 mg bd for seven days. If azithromycin is to be prescribed an extended course of 500 mg stat, then 250 mg daily for four days is to be preferred over 1 g stat. In men with persistent NGU, M. genitalium NAAT testing is recommended if not previously undertaken, as is Trichomonas vaginalis NAAT testing in populations where T. vaginalis is detectable in >2% of symptomatic women. © The Author(s) 2016.

The objective of this study was to demonstrate and evaluate a research polymerase chain reaction (PCR assay, for the detection of MG in cervical samples of a tested population of women attending gynecology clinics in Bosnia and Herzegovina. The Multitarget Real-Time (MTRT PCR, utilizing the ABI 7900HT, the sequence detection system, was performed for the detection of MG. Cervical samples (N=97 from females were divided into three types of patient groups: Group 1: patients who had known abnormal clinical cytology reports (N=34; Group 2: patients who reported a history of genitourinary infections (N=22; and Group 3: patients not in either groups 1 or 2 (N=41. Overall, 14,43% (14/97 of those tested were positive for MG. A positive sample was defined as having a cycle threshold cross point (Ct < 40,0 with a fluorescent detection comparable to the low positive control utilized during the run. This study validated the use of MTRT PCR as a reliable method for the detection of MG in clinical specimens and should facilitate large-scale screening for this organism.

The AGS and CGS data sets used for the project were recorded by SGU, DEMA, NGU (Geological Survey of Norway), and SSI (Swedish Radiation Protection Institute). Most of the project effort has been directed towards analysing AGS and CGS data with point source signals recorded at the Barents Rescue 2001 LIVEX exercise at Boden in Sweden. Possibilities and limitations for the method have been identified. (au)

  7. Western equatorial African forest-savanna mosaics: a legacy of late Holocene climatic change?

    Directory of Open Access Journals (Sweden)

    Full Text Available Past vegetation and climate changes reconstructed using two pollen records from Lakes Maridor and Nguène, located in the coastal savannas and inland rainforest of Gabon, respectively, provide new insights into the environmental history of western equatorial African rainforests during the last 4500 cal yr BP. These pollen records indicate that the coastal savannas of western equatorial Africa did not exist during the mid-Holocene and instead the region was covered by evergreen rainforests. From ca. 4000 cal yr BP a progressive decline of inland evergreen rainforest, accompanied by the expansion of semi-deciduous rainforest, occurred synchronously with grassland colonisation in the coastal region of Gabon. The contraction of moist evergreen rainforest and the establishment of coastal savannas in Gabon suggest decreasing humidity from ca. 4000 cal yr BP. The marked reduction in evergreen rainforest and subsequent savanna expansion was followed from 2700 cal yr BP by the colonization of secondary forests dominated by the palm, Elaeis guineensis, and the shrub, Alchornea cordifolia (Euphorbiaceae. A return to wetter climatic conditions from about 1400 cal yr BP led to the renewed spread of evergreen rainforest inland, whereas a forest-savanna mosaic still persists in the coastal region. There is no evidence to suggest that the major environmental changes observed were driven by human impact.

    1980-01-01

    A method of the separation with anion-exchange chromatography and of the coulometric detection of uranium in seawater was investigated. The size of the separation column used was 9 mm in inside diameter and 100 mm in length, and strong basic anion-exchange resin (Hitachi No. 2632) of carbonate form was packed in the column. A concentrator with two mini-columns in which the same resin was packed was applied for the preconcentration of uranium in seawater containing 20 g of potassium thiocyanate and 10 ml of hydrochloric acid per liter. Good result was obtained when a mixed solution of sodium carbonate (0.12 mol/l), sodium bicarbonate (0.08 mol/l), sodium bisulfite (0.03 mol/l) and sodium chloride (0.5 mol/l) was used as an eluent for the separation of uranium from vanadium. Sodium bisulfite was of use for dropping the background current based on an electrochemical reduction of dissolved oxygen. Sodium bicarbonate acted as an eliminator of an unknown peak by its bufferise effect. The optimum working electrode potential for the detection was -1.45 V vs. ferri-ferrocyanide. The detection limit was 3.2 x 10 -10 mol (80 ngU). The coefficient of variation at 3.0 ppb was about 4% (n=5) for seawater analysis. And the analysis time was approximately 1.5 hours. (author)

    NGU conducted an airborne geophysical survey in Mo i Rana area in July 2012. This report describes and documents the aquisition, processing and visualization of recorded datasets. The geophysical survey results reported herein are 1414 line km. The Geotech Ltd. Hummingbird frequency domain system supplemented by optically pumped cesium magnetometer and 1024 channels RSX-5 spectrometer was used for data aquisition. The survey was flown with 100 m line spacing, line direction of 180 deg North-South (in the west) and 150 deg NorthWest-SouthEast (in the east) with the average speed 96 km/h. The average terrain clearance of the bird was 55 m. Collected data were processed by AR GeoConsulting using Geosoft Oasis Montaj software. Raw total magnetic field data were corrected for diurnal variation and levelled using standard micro levelling algorithm. EM data were filtered and levelled using both automated and manual levelling procedure. Apparent resistivity was calculated from in-phase and quadrature data for each of the five frequencies separately using a homogeneous half space model. Apparent resistivity dataset was levelled and filtered. Radiometric data were processed using standard procedures recommended by International Atomic Energy Association (IAEA). All data were gridded with the cell size of 25 m and presented as shaded relief maps at the scale of 1:25 000.(Author)

  10. Geologic survey of a geothermal heating plant at the Hovdejordet, Bodoe tenant association, Bodoe

    2002-01-01

    The Norwegian Geological Survey (NGU) has investigated the possibilities of finding a suitable heating source for heat pump based heating for the Bodoe tenant association's new housing at the Hovdejordet in central Bodoe. Energy extraction from solid rock was found to be possible. A 170 m deep well was drilled and studied by use of optic televiewer. In addition, the temperature, electrical conductivity and natural gamma radiation were logged. Heat conductivity in mineral test samples from the area was measured as well. The heat conductivity in the ground rock was good i.e. it would be possible to get relatively much heat from each drilled meter of well. The clay covering above the rock is less than 10 m which implies that large drill costs for drilling in large uncompacted material covers may be avoided. The drill hole logging with the televiewer showed a significant main fracture direction which coincided with the rock stri ata and fall in the area. There are many mineralised fractures but fractures with measurable openings were not observed. This may imply small ground water flows and a sizeable contribution from this source may therefore not be counted on. The temperature gradient is small. The drilling of deep wells would then not lead to significant energy gains. A temporary conclusion is that it would be profitable to combine energy extraction from outdoor air and energy wells. Preliminary suggestions are prepared for drill hole based energy storage

    2007-07-01

    This First Edition of the SEDIFLUX Manual is an outcome of the European Science Foundation (ESF) Network SEDIFLUX - Sedimentary Source-to-Sink-Fluxes in Cold Environments (2004 - 2006) (http://www.ngu.no/sediflux, http://www.esf.org/sediflux). The development of this publication has been based on four ESF SEDIFLUX Science Meetings, which were held in Saudarkrokur (Iceland), June 18. - 21., 2004, Clermont-Ferrand (France), January 20. - 22., 2005, Durham (UK), December 16. - 19., 2005 and Trondheim (Norway), October 29. - November 2., 2006. The aim of this Manual is to provide guidance on developing quantitative frameworks for characterising catchment (field-based) sediment budget studies, so that: (1) baseline measurements at SEDIFLUX/SEDIBUD key test catchments are standardised thus enabling intersite comparisons, and (2) long-term changes in catchment geosystems as related to climate change are well documented. The main focus is on non-glacial processes, although within the context of glacierised catchments glacial sediment transfer processes are assumed as inputs/outputs of the periglacial / paraglacial system. This First Edition of the SEDIFLUX Manual will be further developed within the I.A.G./A.I.G. Working Group SEDIBUD - Sediment Budgets in Cold Environments (http://www.geomorph.org/wg/wgsb.html).(auth)

    The Geological Surveys of Finland (GTK), Norway (NGU) and Russia (CKE) are carrying out a major collaborative regional geochemical mapping project in an area north of the Arctic Circle in these three countries. The aims are to establish regional geochemical maps of the distribution of heavy metals and radionuclides within the study area, to build up a soil sample bank for use in future studies and to assess the environmental impact of the heavy metal industry and nuclear activity in this ecologically vulnerable area. A detailed study of eight small catchments situated at different distances from major industrial centres within the project area was carried out as part of the main project during 1994. The objective of this study was to better understand the processes occurring within catchment areas and to identify inter-relationships between different media. A high variation of the natural occurrence of Th and U due to differing bedrock lithologies was observed in the catchment study. Surface concentrations of 134 Cs and 137 Cs were generally low, but highly variable on the small scale. Regional maps will be ready in 1996 covering 18,000 km 2 . 4 refs., 3 figs

    Full Text Available A necessidade de registro das línguas de sinais sempre esteve presente na educação de surdos. Esse estudo de caráter bibliográfico destaca as primeiras tentativas de representação gráfica do alfabeto manual e de línguas de sinais em diferentes períodos históricos até o ano de 1960, ano em que as pesquisas línguístícas surgem em relação a tal língua. O objetivo deste estudo é o de fornecer informações que levem a compreender como ocorreram os primeiros registros, quem foram os seus autores e quais eram os discursos sobre os sinais desenhados à época de cada produção. Observa-se que ao longo da história muitas tentativas de representação surgiram e algumas constituíram-se como alicerces para os tipos de produção gráfica que temos na contemporaneidade. E neste sentido, as pesquisas de William Stokoe, linguista americano, tiveram um papel decisivo: o de comprovar cientificamente que as línguas de sinais se constituem verdadeiramente como línguas.

  14. Mapping of caesium fallout from the Chernobyl accident in the Jotunheimen area

    As a consequence of the Chernobyl accident, several areas in Norway received radioactive fallout. One of these areas is the eastern part of Jotunheimen in central Norway. Immediately after the accident in 1986, the Geological Survey of Norway (NGU) performed airborne gamma-ray spectroscopy in central Norway. At that time, it was not possible to calculate reliable radionuclide concentrations, and the data were presented as total counts per second. Several man-made radionuclides were present in the initial fallout, but due to short half-lives, most of these have now disintegrated into stable isotopes. 137Cs, with a half-life of 11.000 days ({approx} 30 years) is still present in the environment in significant quantities, leading to high radioactivity levels in meat from reindeer and sheep. To obtain a detailed map of the caesium fallout concentration in Jotunheimen, an airborne gamma-ray spectrometry (AGRS) survey was carried out, focussing on reindeer grazing areas. This project was a cooperation between Reindeer Husbandry Administration, Norwegian Radiation Protection Authority and the Geological Survey of Norway. (auth)

  15. On the evaluation of scalarproducts of nonlinear spinorfield state functionals

    International Nuclear Information System (INIS)

    Stumpf, H.

    1981-01-01

    The metrical structure of the linear state space of a quantized nonlinear field cannot be given a priori. Rather it is determined by the dynamics of the field itself. For the evaluation of state norms and scalarproducts this metric must be known. In functional quantum theory the metrical structure is expressed by the metric tensor G(j) in functional space. Equivalent to the knowledge of G(j) is the knowledge of the set of dual state functionals ( vertical stroke S(j,a)>) together with the corresponding original state functionals ( vertical stroke F(j,a)>). In preceding papers attempts were made to calculate G(j). In this paper an approach is made to determine the dual state functionals directly. Equations are derived which have to be satisfied by the dual functionals. The method works in those state sectors which are characterized by real (monopole) particles or monopole ghosts, while it does not work for multipole ghost states. Norm calculations are performed for local monopole fermion states and local monopole boson states of the lepton- quark model derived in a preceding paper. (orig.)

    The development of new therapeutic modalities involves the use of drug carrier, such as liposomes, which can modify pharmacokinetic and bio-distribution of drug profile. Polyene antibiotics incorporation into liposomes improves its availability at the site, bio-distribution and therapeutic index mainly through the engulfment of liposomes by circulating monocytes/macrophages and transportation to the site of infection. Polyene antibiotics (AmB, SJA-95, HA-1-92) and other antibiotics (streptomycin, tobramycin, quinolones, anti-tubercular and anti-cancer drugs), liposomal preparations are described with possible advantages from therapeutic efficacy and toxicity point of view. The polyene macrolide antibiotics liposomal preparations proved to be more effective in the treatment of systemic mycosis. The AmB-cyclodextrin derivatives inclusion complex is a major breakthrough in liposomal preparation which can be converted into aqueous phase of liposome. Liposomal drug incorporated preparation has been one of the important areas of research for developing the existing polyene antibiotics into useful chemotherapeutic agents in clinical medicine. In recent past other antibiotics have also been incorporated into liposomes using wide variety of materials, phosphatidylethanolamine derivatives (pegylated liposomes, enzyme sensitive conjugates, fluidosomes of anti-cancer drugs and poly lactic/glycolic acid microspheres for anti-tuberculosis drugs). In addition, attempts were also made to extend the receptor mediated drug targeting and to review some relevant patents.

  1. A Vietnamese Reading of the Master’s Classic: Pha .m Nguyê ˜n Du’s Humble Comments on the Analects as an Example of Transformative Learning

    2017-06-01

    Full Text Available Phạm Nguyễn Du’s influential text Humble Comments on the Analects (Luận Ngữ Ngu Án 論語愚按 is an outstanding example of a Vietnamese adaptation and reworking of an East Asian intellectual tradition. In organizing his work, Phạm departed from convention by rearranging the extant chapters of the Analects into four “books”: “Sage” (Thánh 聖, “Learning” (Học 學, “Official” (Sĩ 仕, and “Politics” (Chính 政. Moreover, Phạm placed particular emphasis on the “Learning” book, and thus underscored his contention that the classic text was especially relevant and meaningful to eighteenth-century Vietnam. This paper attempts to read Phạm’s work in the contexts of both Confucian tradition and contemporary education. First, it examines Phạm’s composition of the Humble Comments based on Jack Mezirow’s theory of transformative learning. Phạm’s writing process in this work presents a fascinating case of transformative learning, in which the author questions received assumptions about the world and himself, puts forward new propositions, and elaborates these via an original reading of a classic. Through the analysis of Phạm Nguyễn Du’s life and his preface to the Humble Comments, one can also gain a better view of the Vietnamese reception of Zhu Xi’s Neo-Confucianism, and more particularly, of Zhu’s dictum of “learning for the sake of one’s self” (weiji zhi xue 為己 之學. Lastly, this dictum will be reappraised to show its validity in contemporary educational contexts.

    To investigate the relationship between chest compression fraction (CCF) and survival outcomes in OHCA, including whether the relationship varied based upon downtime from onset of arrest to provision of cardiopulmonary resuscitation (CPR) by emergency medical services (EMS). Data from resuscitations performed by St John Ambulance Western Australia (SJA-WA) paramedics between July 2014 and June 2016 was captured using the Q-CPR feedback device. Logistic regression analysis was used to study the relationship between CCF and return of spontaneous circulation (ROSC). Various lengths of Q-CPR data were used ranging from the first 3min to all available episode data. Cases were subsequently divided into groups based upon downtime; ≤15min, >15min and unknown. Univariate and multivariable logistic regression analyses were performed in each group. There were 341 cases eligible for inclusion. CCF >80% was significantly associated with decreased odds of ROSC compared to CCF≤80% (aOR: 0.49, 95%CI: 0.28-0.87). This relationship remained significant whether the first 3min of data was used, the first 5min or all available episode data. Among the group with a downtime >15min, CCF was significantly lower for those who achieved ROSC compared to those who did not (mean (SD): 73.01 (12.99)% vs. 83.05 (9.38)% p=0.002). The adjusted odds ratio for achieving ROSC in this group was significantly less with CCF>80% compared to CCF≤80% (aOR: 0.06, 95%CI: 0.01-0.38). We demonstrated an inverse relationship between CCF and ROSC that varied depending upon the time from arrest to provision of EMS-CPR. Copyright © 2017 Elsevier B.V. All rights reserved.

    Strategic enrichment of microcosms derived from wood foragers can facilitate the discovery of key microbes that produce enzymes for the bioconversion of plant fiber (i.e., lignocellulose) into valuable chemicals and energy. In this study, lignocellulose-degrading microorganisms from the digestive systems of Canadian beaver (Castor canadensis) and North American moose (Alces americanus) were enriched under methanogenic conditions for over 3 years using various wood-derived substrates, including (i) cellulose (C), (ii) cellulose + lignosulphonate (CL), (iii) cellulose + tannic acid (CT), and (iv) poplar hydrolysate (PH). Substantial improvement in the conversion of amended organic substrates into biogas was observed in both beaver dropping and moose rumen enrichment cultures over the enrichment phases (up to 0.36-0.68 ml biogas/mg COD added), except for enrichments amended with tannic acid where conversion was approximately 0.15 ml biogas/mg COD added. Multiplex-pyrosequencing of 16S rRNA genes revealed systematic shifts in the population of Firmicutes, Bacteroidetes, Chlorobi, Spirochaetes, Chloroflexi, and Elusimicrobia in response to the enrichment. These shifts were predominantly substrate driven, not inoculum driven, as revealed by both UPGMA clustering pattern and OTU distribution. Additionally, the relative abundance of multiple OTUs from poorly defined taxonomic lineages increased from less than 1% to 25-50% in microcosms amended with lignocellulosic substrates, including OTUs from classes SJA-28, Endomicrobia, orders Bacteroidales, OPB54, and family Lachnospiraceae. This study provides the first direct comparison of shifts in microbial communities that occurred in different environmental samples in response to multiple relevant lignocellulosic carbon sources, and demonstrates the potential of enrichment to increase the abundance of key lignocellulolytic microorganisms and encoded activities.

    2000-01-01

    In March 2000 the Norwegian Geologic Survey (NGU) was requested to carry out ground water investigations in the Lena area at Melhus centre by the firms E-Tek AS and Statoil. The background for the investigations was the plans of exploiting ground heat connected to a housing project lead by Selmer Bolig AS. The aim of the project was to document the possibilities for extracting ground heat from loose soil well(s) in the selected construction area. The needed amount of water is in the size of 50 m 3 /hour (14l/s). In addition the conditions of currents, ground water quality and possibilities for refiltering of the ground water was to be mapped. In conclusion it may be said that it most likely will be possible to meet the stipulated water requirements (50 m 3 /hour) by establishing a full scale production well within the construction area. The ground water currents in the Lena area run from north to south. The ground water surface is relatively flat with an incline of 0.1 - 0.2 % (1-2 mm/m). The possibilities for refiltering pumped water seem to be good. The conditions should be mapped more closely through refiltering tests. All of the collected ground water samples exceed the limiting values stipulated by the drinking water regulations as to alkalinity, sulphate, calcium, potassium and manganese. The tests from Obs2 and from the ''municipal well'' exceed the limits for chloride and sodium as well. This indicates that unwanted precipitations of both chalk and manganese may occur. Large quantities of sea salts (chloride and sodium) may also have a corrosive effect. Through calculations using the Ryznar's Stability Index (RSI) it is evident that the tests from Obs1 and Obs2 are in the limiting area between ''problem free water'' and ''corrosive water'', while the water from the municipal well must be characterised as very corrosive. According to information from the managing personnel there have not been registered problems with precipitations or corrosion in heat

Como las corrientes fluviales pueden utilizarse con diversos fines: para obtener agua potable, para el consumo industrial, como lugar de recreo, para la pesca, el riego o la navegacion, hay que evaluar cuidadosamente los efectos de la evacuacion en cada uno de los casos mencionados. Los criterios actualmente establecidos no proporcionan una base suficiente para determinar el limite admisible de evacuacion, a no ser que se conozcan las cantidades.de cada radionuclido ya presentes en el agua y su comportamiento al ser arrastrados por la corriente.

    Full Text Available In a book entitled The Sermon on the Mount: The modern Quest for its meaning, theologian Clarence Bauman (1985 discusses, inter alia, Jesus’ teaching on “anger”. The book opens with a chapter on Tolstoy: “Leo Tolstoy: The moral challenges of literal interpretation”: “Christ’s first commandment is “Do not be angry” (Matthew 5: 22-25. Tolstoy noted that the text had been tampered with by redactors. By the fifth century the word εικη, meaning “needlessly” or “without cause,” had been inserted into the initial uncondi-tional statement: “Whosoever is angry with his brother without a cause...”. But what did Jesus really teach about “anger”? The term used in Matthew’s Gospel (5:22 is of course not the English word anger but the Greek word orgizomai - and the two don’t mean the same. The term used by Tolstoy - the Russian word gnevat’sja - is different in meaning from both anger and orgizomai. But the word used by Jesus was neither English, nor Greek, nor Russian, but Aramaic. So what did that Aramaic word mean - and what did Jesus intend to say with it? Tolstoy’s impulse to look for the “literal interpretation” is understandable, but as this chapter shows, the idea that we can pinpoint what Jesus meant with one word, from a particular lan-guage (be it Russian, English, Greek or Aramaic is simplistic. The paper argues that in order to fully under-stand Jesus’ teaching about “anger” in a precise and unbiased way, we need to go beyond single words of this or that language, and to try to articulate it through simple sentences couched in universal (i.e. universally-contestable words. Furthermore, the paper shows that what applies to Jesus’ teaching about emotions applies also to Jesus’ “emotional practice”. What did he feel when he saw someone doing some-thing very bad, or someone to whom something very bad was happening? As the paper demonstrates, the “Natural Semantic Metalanguage” (NSM

    A histochemical study using conventional carbohydrate histochemistry (periodic-acid staining including diastase controls, alcian blue staining at pH 1 and 2.5) as well as using a battery of 14 fluorescein isothiocyanate (FITC)-labelled lectins to identify glycoconjugates present in 10 different areas of the skin of a catfish (Arius tenuispinis) was carried out. The lectins used were: mannose-binding lectins (Con A, LCA and PSA), galactose-binding lectins (PNA, RCA), N-acetylgalactosamine-binding lectins (DBA, SBA, SJA and GSL I), N-acetylglucosamine-binding lectins (WGA and WGAs), fucose-binding lectins (UEA) and lectins which bind to complex carbohydrate configurations (PHA E, PHA L). Conventional glycoconjugate staining (PAS staining, alcian blue at pH 1 and 2.5) showed that the mucous goblet cells contain a considerable amount of glycoconjugates in all locations of the skin, whereas the other unicellular gland type, the club cells, lacked these glycoconjugates. The glycoproteins found in goblet cells are neutral and therefore stain magenta when subjected to PAS staining. Alcian blue staining indicating acid glycoproteins was distinctly positive at pH 1, but gave only a comparable staining at pH 2.5. The mucus of the goblet cells therefore also contains acid glycoproteins rich in sulphate groups. Using FITC-labelled lectins, the carbohydrate composition of the glycoproteins of goblet cells could be more fully characterized. A distinct staining of the mucus of goblet cells was found with the mannose-binding lectins LCA and PSA; the galactosamine-binding lectins DBA, SBA and GLS I; the glucosamine-binding lectin WGA; and PHA E which stains glycoproteins with complex carbohydrate configurations. No reaction occurred with the fucose-binding lectin UEA and the sialic acid-specific lectin SNA. In addition, the galactose-binding lectins PNA and RCA showed only a weak or completely negative staining of the mucus in the goblet cells. The specificity of the lectin staining

    combinations of rock mass properties and persistent brittle structural patterns related to folding or regional stress fields. We analysed the processes leading to DSGSD onset and evolution by testing combinations of: a) rock mass constitutive models; b) in situ stress fields; c) hydro-mechanical coupling; d) dynamic loadings. DEM results, validated using field evidence and discussed against the results of continuum-based Finite-Element models (Agliardi et al., 2014; Barbarano et al., 2015), suggest that DSGSD failure mechanisms are constrained by fold-related brittle structures, and stress and hydrologic conditioning of deglaciation were key triggers modulated by active tectonic processes.

    The loss of lives caused by landslides in Norway is smaller than in other countries due to the low population density in exposed areas. However, annual economic losses from damage to properties and infrastructures are vast. Yet nationally coordinated efforts to manage and reduce landslide and snow avalanche risk are a recent challenge, having started only in the last decade. Since 2009, this has been a task of the Norwegian Water Resources and Energy Directorate (NVE) under the Ministry of Petroleum and Energy. Ongoing work includes collection of landslide data, production of susceptibility and hazard maps, planning of mitigation measures along with monitoring and early warning systems, assistance to areal planning, providing expertise in emergencies and disseminating information to the public. These activities are realized in collaboration with the Norwegian Geological Survey (NGU), the Meteorological Institute, the Road and Railway authorities, universities and private consultant companies. As the total need for risk mitigating initiatives is by far larger than the annual budget, priority assessment is crucial. This brings about a number of ethical questions. 1. Susceptibility maps have been produced for the whole country and provide a first indication of areas with potential landslide or snow avalanche hazard, i.e. areas where special attention and expert assessments are needed before development. Areas where no potential hazard is shown can in practice be developed without further studies, which call for relatively conservative susceptibility maps. However, conservative maps are problematic as they too often increase both cost and duration of building projects beyond the reasonable. 2. Areas where hazard maps or risk mitigation initiatives will be funded are chosen by means of cost-benefits analyses which are often uncertain. How to estimate the benefits if the real probability for damage can only be judged on a very subjective level but not really calculated

La experiencia adquirida en la aplicacion de esos dos metodos por el Argonne National Laboratory a cantidades relativamente grandes de tubo de diversas procedencias se estudia desde el punto de vista del costo mas bajo posible a que pueda efectuarse la inspeccion por unidad de longitud del tubo de que se trate. En la presente seccion se expone ademas en forma concisa la experiencia adquirida en Argonne con los modernos metodos de impulsos electromagneticos. Se examina la influencia critica, pero generalmente inapreciada, que tienen en el costo de la inspeccion el diametro y el espesor de pared del tubo. Teniendo en cuenta que el problema de la inspeccion en condiciones economicas guarda una estrecha relacion con el numero medio de defectos admisibles, se estudian asimismo los promedios y las normas que se aplican en Argonne. Por ultimo, se enumeran los obstaculos de orden teorico y practico para reducir el costo de la inspeccion de piezas sobre esa base, y se evaluan las posibles reducciones de costo que podrian lograrse en lo futuro aplicando los metodos de ensayo ultrasonicos y electromagneticos.

    en algunos aspectos la atmosfera puede compararse a la hidrosfera y a la litosfera como posible recipiente de desechos, la presencia de desechos radiactivos en suspension en el aire puede afectar de manera mas inmediata a la seguridad de la vida humana. La contaminacion de la atmosfera plantea dos problemas completamente distintos: 1) uno, de alcance limitado, que se circunscribe a la proximidad inmediata de una planta nuclear, y 2) otro mas universal y a largo plazo, debido a la extension de la contaminacion atmosferica. Los problemas de contaminacion de alcance limitado se vienen planteando desde hace muchos anos como consecuencia de la evacuacion de desechos no radiactivos tales como anhidrido sulfuroso, acido fluorhidrico y humos procedentes de la combustion del carbon. Sin embargo, los aspectos cientificos de este problema solo se empezaron a estudiar detenidamente en el curso de los ultimos anos. Las condiciones meteorologicas desempenan un papel importante en esta cuestion. En ciertos casos, las velocidades de descarga se han podido regular en funcion de las predicciones meteorologicas. No obstante, la solucion fundamental consiste aun en mantener las velocidades de descarga en los valores minimos posibles.

(author) [Spanish] El problema de calcular la carga corporal de plutonio despues de haber inhalado oxido de plutonio tiene considerable importancia practica y, debido a que el oxido de plutonio es insoluble, no se pueden considerar validas las determinaciones de plutonio en la orina. La memoria revisa los datos biologicos publicados acerca de experimentos con sabuesos y, en dos casos, con seres humanos. De estos datos se deduce que existen razones para creer que la carga corporal derivada de la inhalacion accidental se puede calcular a partir de mediciones del plutonio excretado por la orina, pasados mas de unos 300 dias desde la absorcion. La memoria discute algunas de las posibles vias de excrecion. Por ultimo, comenta la presencia de plutonio insoluble en los pulmones y en los nodulos linfaticos de los bronquios desde el punto de vista de la proteccion radiologica y destaca la necesidad de tener en cuenta el hecho de que el plutonio se encuentra en forma de particulas.

    Full Text Available Embora sejam as forrageiras mais importantes para a pecuária de corte (bovinocultura de corte no Brasil, em certas épocas ou condições, Brachiaria spp. podem ser tóxicas e causar surtos de fotossensibilização hepatógena que determinam significativas perdas econômicas. Animais que se alimentam em pastos de Brachiaria spp. comumente apresentam macrófagos espumosos isolados ou agrupados, além de cristais no interior de ductos biliares. Saponinas esteroidais têm sido identificadas nestes cristais e são responsabilizadas por lesar o fígado levando ao acúmulo de filoeritrina. Por vezes, imagens negativas desses cristais podem estar presentes no citoplasma de macrófagos espumosos. A patogênese de formação e o tipo de material armazenado nas células espumosas ainda são desconhecidos. A técnica de lectino-histoquímica visa auxiliar na detecção desses macrófagos e, consequentemente, no diagnóstico, além de identificar quais os resíduos de açúcares específicos que estão presentes no citoplasma das células espumosas. Assim, este trabalho teve por objetivo identificar quais lectinas são mais indicadas na detecção de saponinas esteroidais no fígado e rim de ovinos com fotossensibilização causada por Brachiaria decumbens. Fragmentos de fígado e rim de quinze ovinos, de ambos os sexos e idade variável, oriundos de Conceição do Mato Dentro, Minas Gerais, e um ovino mantido em pastagem livre de Brachiaria spp. foram avaliados pela técnica de lectino-histoquímica. Quatorze lectinas foram utilizadas (Con-A, DBA, SBA, PNA, SJA, RCA-I, UEA-I, WGA, SWGA, GSL, PSA, PHA-L, PHA-E e LCA. Verificou-se que, no fígado de ovinos com fotossensibilização provocada pela ingestão de Brachiaria decumbens, a lectina PNA apresentou especificidade e acentuada reatividade aos macrófagos espumosos, bem como especificidade e leve reatividade aos hepatócitos; a lectina WGA teve especificidade e moderada reatividade aos macr

    inventarios es la de salvaguardar los intereses de la Comision, evaluar la cuantia de las perdidas y controlar las medidas adoptadas para el almacenaje de los desechos. Para el recuento de las existencias el inspector puede efectuar materialmente el inventario, participar en el o comprobarlo. Este ultimo procedimiento es el que da mejores resultados. Las operaciones de recuento, precedidas de una reunion preparatoria para fijar las modalidades, se efectuan en dos tiempos: la comprobacion del inventario ponderal y la comprobacion de la contabilidad fisica. Las cuestiones que pueden plantearse durante el inventario se refieren a las discrepancias en el peso y el contenido, la eleccion del equipo de pesada, los residuos y la evaluacion de las perdidas. Los metodos de inventario no deben diferir de un pais a otro. Parece preferible subrayar las dificultades que se presentan durante las operaciones y estudiar en comun los medios para evitarlas.

    distributor (10 mA/channel). The box can independently supply 4 groups of 40 PMTs each. The voltage setting can be made manually, through keyboard and LCD display located on the front panel using a μC board which also contains a CAN interpreter, SJA 1000, that makes the serial CAN-bus link remotely. The connection is bidirectional allowing both the setting of output voltages and the reading of the output voltage and current values. The power supply has good output features, shortcut protection and special voltages. The output voltages for a group are given. The box dimensions are: 480 x 128 x 525 mm. The voltages are transmitted trough HV coaxial cables with SHV connectors. The PMTs of FEU-115m10 type were used. In the following HV system will be adapted to be used to supply PMTs of Hamamatsu type R7899 20 which have been largely investigated by LHCb collaboration. HV Power Supply is going to be integrated in CAN network. This HVPS with parallel power groups of fast PMTs has the following advantages: a) outside PMTs supply (power dissipation is not inside HCAL modules); b) very good stability for all HV supplies (photocathode and dynodes); c) low ripple because of distributor supplementary stabilization with series transistors; d) great reserve of current (it allows high counting rates); f) being operated remotely it needs not to be radiation-proof; g) easy service. The system can be used in any experiments with many fast PMTs. (authors)

Pero al aplicarlo a gran presion o si en el momento de la inyeccion el rinon estaba infectado, parte del torotrasto puede haberse depositado en los tejidos. Es posible que no se identifique por medios radiograficos un numero mayor de estos depositos porque se asemejan mucho a los depositos de calcio en el rinon y hace falta cierta experiencia para diferenciar unos de otros. Los autores, en colaboracion con la clinica de urologia de la Universidad del Sarre han descubierto siete casos en estos ultimos anos. Cuando el deposito se encontro exclusivamente en un rinon, cosa que ocurrio con seis pacientes, se extirpo el organo. El examen histologico revelo cinco carcinomas y en un rinon se observaron alteraciones degenerativas muy pronunciadas. Segun las observaciones de los autores, el tiempo necesario para el desarrollo de tales carcinomas es de 20 a 25 anos. En dos casos pudieron examinar al paciente. con el antropogammimetro y medir las sustancias radiactivas presentes en la orina y el toron en el aliento. Hicieron todas estas determinaciones antes y despues de la nefrectomia. Asimismo, midieron los rayos gamma emitidos por el organo aislado.

    measurements data and support profound statistical analysis of storaged and modeled on demand data. In particular, one can run the integrated models, preprocess modeling results data, using dedicated modules for numerical processing perform analysys and visualize obtained results. New functionality recently has been added to the statistical analysis tools set aimed at detailed studies of climatic extremes occurring in Northern Asia. The VRE element is also supporting thematic educational courses for students and post-graduate students of the Tomsk State University. In particular, it allow students to perform on-line thematic laboratory work cycles on the basics of analysis of current and potential future regional climate change using Siberia territory as an example (Gordova et al, 2013). We plan to expand the integrated models set and add comprehensive surface and Arctic Ocean description. Developed VRE element "Climate" provides specialists involved into multidisciplinary research projects with reliable and practical instruments for integrated research of climate and ecosystems changes on global and regional scales. With its help even a user without programming skills can process and visualize multidimensional observational and model data through unified web-interface using a common graphical web-browser.

    countries. This makes the direct use of primary data in an integrated way very difficult and also hampers use of the data sets in a harmonised way to produce multidisciplinary data products and services. To ensure interoperability with other marine environmental data types Geo-Seas ISO19115 metadata, OGC and GeoSciML standards will be used as the basis for the metadata profiles for the geological and geophysical data. This will be largely achieved by modifying the SeaDataNet metadata standard profile (Common Data Index or CDI), which is itself based upon the ISO19115 standard, to accommodate the requirements of the Geo-Seas project. The overall objective of Geo-Seas project is to build and deploy a unified marine geoscientific data infrastructure within Europe which will in effect provide a data grid for the sharing of marine geological and geophysical data. This will result in a major improvement in the locating, accessing and delivery of federated marine geological and geophysical data and data products from national geological surveys and research institutes across Europe. There is an emphasis on interoperability both with other disciplines as well as with other key framework projects including the European Marine Observation and Data Network (EMODNet) and One Geology - Europe. In addition, a key objective of the Geo-Seas project is to underpin European directives such as INSPIRE as well as recent framework programmes on both the global and European scale, for example Global Earth Observation System of Systems (GEOSS) and Global Monitoring for Environment and Security (GMES), all of which are intended to encourage the exchange of data and information.

    structure of Icelandic companies 2008-2013.Viðfangsefni greinarinnar er að fjalla um þróun á skipulagi, ferlum og umfangi í starfsemi 200 stærstu íslensku fyrirtækjanna á árunum 2004 til 2007. Gerð var rannsókn að erlendri fyrirmynd í rannsóknarverkefninu Innform á Íslandi. Markmiðið var að kanna hvort ný skipulagsform væru að ryðja sér til rúms eða hvort ný form væru að þróast samhliða eldri formum. Spurningalisti var sendur í pósti til 192 fyrirtækja og svör bárust frá 62 fyrirtækjum (32.3% svörun. Helstu niðurstöður eru þær að stærstu fyrirtækin leggja einna mest áherslu á afurðatengt stjórnskipulag og leggja jafnframt aukna áherslu á viðskiptavininn í skipulagi sínu. Stór hluti fyrirtækjanna (um 70% styðst hins vegar líka eða eingöngu við starfaskipulag. Þessar niðurstöður benda til þess að skipulag stórra íslenskra fyrirtækja sé um margt sambærilegt við þær erlendu rannsóknir sem miðað var við. Íslensku niðurstöðurnar benda líka til þess að skipulag íslensku fyrirtækjanna sé að þróast á þessu tímabili. Verkefnaskipulag er að ryðja sér til rúms og vísbendingar eru um að skipulag sem grundvallast á eignarhaldsfélögum hafi aukist talsvert á tímanum sem rannsóknin nær til. Áherslan á mannauðsstjórnun mælist með mestu áherslubreytinguna yfir tímabilið af þeim þáttum sem mældir voru. Breytingar á umfangi, úthýsingu og samstarfi milli fyrirtækja mælast frekar litlar yfir tímabilið og breytingarnar ganga skemur hér á landi en virðist hafa verið tilfellið í Evrópu áratugi fyrr. Rannsóknir sem byggja á sama mælitæki og jafnframt á raundæmum eru fyrirhugaðar til að kanna nánar þróun á skipulagi íslenskra fyrirtækja yfir tímabilið 2008-2013.

(author) [Spanish] En la tecnologia de los alimentos, el empleo de las radiaciones en lugar de los actuales metodos de conservacion solo puede considerarse cuando permite obtener productos de mejor calidad o mas baratos o cuando no existe ningun otro metodo utilizable. Teniendo esto presente, en la memoria se examina la labor que en el Instituto Danes de Investigaciones sobre la Carne se ha realizado con tocino en lonchas, jamon enlatado, pastel de carne en lata y alimentos para los animales, es decir, harina de carne y huesos, y harina de sangre. De los resultados de los experimentos se desprende que la aparicion de mal sabor en los productos carnicos irradiados es un problema muy grave y el obstaculo mas importante que se opone a la irradiacion de la' carne durante su tratamiento. Por tanto, es esencial que en lo sucesivo las investigaciones se concentren en la manera de evitar la alteracion del sabor provocada por la irradiacion. En la memoria se mencionan varios metodos para resolver este problema y se informa sobre la labor llevada a cabo en Dinamarca que ha consistido principalmente en exponer latas de conserva a intensidades muy elevadas con una distribucion desigual de las dosis.

La insolubilidad del molibdeno impide concentrar por evaporacion las soluciones de los productos de fision. Por tal motivo, los autores han estudiado la posibilidad de solubilizar el molibdeno agregandole reactivos tales como el hierro o los iones fosforicos. De este modo, es posible obtener soluciones finales de 60 g/l Mo con hierro, 100 g/l Mo con PO{sub 4}H{sub 3}. Los volumenes que es preciso almacenar siguen siendo importantes (sobre todo con el hierro) y por eso se ha estudiado la calcinacion de los nitratos en un lecho fluidizado. La reaccion tiene lugar a los 400 Degree-Sign C aproximadamente. El comportamiento del rutenio y la friabilidad del solido calcinado (importante formacion de particulas menudas) ha inducido a los autores a reemplazar este procedimiento por el de preparacion de vidrios fosfAtados.

    comme milieu de stockage, en les comparant aux verres au borosilicate. (author) [Spanish] El principal factor que es preciso tener en cuenta al proceder a la eleccion de un vidrio adecuado para almacenar por largos periodos desechos de productos de fision es el metodo de almacenamiento que se va a aplicar; el segundo factor es el grado de seguridad que ofrece la elaboracion del vidrio en un establecimiento de alta actividad. A su vez, los factores que interesan para el almacenamiento son la resistencia a la lixiviacion, la estabilidad termica y a las radiaciones y la proporcion de desechos que se pueden incorporar a la masa vitrea, mientras que las propiedados fisicas y quimicas de los aditivos vitrificantes, asi como el punto de fusion y la viscosidad del vidrio mismo, son factores que intervienen mas bien en el proceso de elaboracion. Los autores examinan la importancia relativa de todos estos factores. Exponen luego los resultados del estudio experimental de los vidrios al borosilicato que se han elegido para, los ensayos en instalacion piloto, incluso el efecto de dosis de radiacion hasta 10{sup 12} rad sobre sus propiedades fisicas y quimicas. Tambien examinaron vidrios de otras composiciones y compararon su posible utilidad, como medio de almacenamiento, con la de los vidrios al borosilicato.

    ia calidad del combustible utilizado se considera indispensable controlar el conjunto del elemento y la totalidad de la produccion. Este control no puede realizarse por micrograffa debido al tiempo prolongado que esta requiere y a sus resultados de caracter parcial. El metodo de control adoptado se basa en el principio de la absorcion de ondas ultrasonicas por los distintos materiales. Dicha absorcion es funcion de la estructura del medio. Si {lambda} es pequena en comparacion col el tamano del grano G, la absorcion resultara debil mientras que si G es del orden de {lambda}/2, la absorcion sera muy considerable. Los primeros ensayos se efectuaron en aire, utilizando ecos multiples y midiendo la altura del primer eco; los siguientes se realizaron por transmision en agua, comparando la altura del eco transmitido con la del inicial. En el control industrial, se compara la amplitud del eco transmitido por el material con la del obtenido usando una probeta patron sometida al tratamiento correcto, de la misma composicion y de igual forma geometrica. La inspeccion se realiza en una maquina especial; los materiales se hacen girar mediante roldanas y los transductores orientables se desplazan a lo largo del elemento. La exploracion helicoidal se lleva a cabo con un paso inferior a 5 mm. El generador de ondas ultrasonicas comprende un sistema de regulacion que mantiene constante la intensidad del eco de referencia. Se presenta una serie de registros obtenidos con diversas aleaciones y, en particular, defectos observados en elementos tratados por induccion durante el avance lineal. Se detectan zonas de tratamiento deficiente, de area inferior a 1 cm{sup 2}. En la actualidad se controlan de esta manera todos los combustibles aleados de bajo contenido de uranio destinados a los reactors G2, EL3, EDF1, EDF2 e INCA, es decir, barras y tubos con diametros comprendidos entre 20 y 95 mm.

    de implantacion consiste en elegir un tamano y una actividad de la fuente adaptados a las dimensiones de la glandula en cuestion. De esta manera, se procura que el procedimiento sea uniforme en todas las implantaciones. La forma de la glandula y el acceso a ella son tales que la mejor manera de lograr su destruccion completa es implantar dos fuentes, consistentes en varillas de Y{sub 2}O{sub 3} sintetizado (de 1 mm de diametro y de longitud adaptada a las dimensiones de la glandula). La actividad de la varilla se elige tambien convenientemente; en los casos caracteristicos esta comprendida entre 2 y 3 me. Los autores han encontrado experimentalmente la relacion entre la dosis de irradiacion por una parte y la geometria y la actividad por otra. Como absorbedor equivalente al tejido, utilizaron cera Mix D; como detector, una pelicula y como patron, una fuente calibrada de {sup 90}Sr ( que se desintegra formando {sup 90}Y).

    los productos irradiados, la aplicacion de las disposiciones legislativas pertinentes, y su promulgacion en los casos en que no existia ninguna. Actualmente, la mayoria delas legislaciones exigen que, antes de que se autoricen la irradiacion y el consumo de los alimentos, se demuestre de manera inequivoca la comestibilidad del producto irradiado. Ahora bien, esta prueba queda fuera del alcance de los paises pequefios y en desarrollo, que serian precisa mente los que mayores beneficios podrian obtener de la aplicacion en escala industrial de las tecnicas de irradiacion, ya que con ello aumentarian tanto la disponibilidad de productos alimenticios de origen local para su consumo en el pais como las posibilidades de exportacion. A titulo de ensayo, el 24 de febrero de 1966 se presento al Ministerio de Sanidad de Israel una solicitud de autorizacion para destinar al consumo patatas blancas irradiadas a fin de evitar su germinacion. La peticion se basaba no en investigaciones realizadas en el pais sino en los resultados de trabajos reseflados en publicaciones extranjeras, solicitandose que se aceptasen como prueba suficiente los ensayos de comestibilidad aprobados por otros gobiernos. En breve se presentara a dicho Ministerio una peticion analoga relativa al consumo de cebollas irradiadas. De tener exito, este procedimiento podria ser adoptado por otros paises con lo que tal vez se facilitase la conclusion de acuerdos internacionales de comercio. Contribuiria sin duda alguna a la generalizacion rapida del empleo de las radiaciones para conservar productos alimenticios en aquellos lugares en que esta tecnica puede resultar economicamente util.

    Full Text Available Teesid: 1960. aastate lõpus toimusid eesti teatris suured muutused. Ilmus nähtus, mida hakati nimetama nooreks režissuuriks. Eeskätt on see seotud Evald Hermaküla, Jaan Toominga, Kalju Komissarovi, Kaarin Raidi jt nimedega. Noor režissuur tõstis mässu ahtaks muutunud realismi raamide vastu, mis ei vastanud noore põlvkonna teatriootustele. Olles mõjutatud ideeliselt radikaalsest eksperimentaalteatrist USAs, aga ka Jerzy Grotowski katsetustest ning teistest avangardsetest liikumistest, muutis see füüsilist teatrikeelt. Tõusis improvisatsiooni osakaal. Teater lakkas olemast dramaturgiliste tekstide esituskoht, vaid hakkas otsima etendustes vahetut kohalolu. Tajuprotsessi hakkas juhtima mängu põhimõte. Suured müüdid dekonstrueeriti, autoritaarsusele vastanduti. Seksuaalsus ilmutas end uuel jõul, toetatud alateadvuse impulssidest. Uue laine radikaalsus kestis 1970. aastate lõpuni, mil see sulandus peavoolu. Murrang teatriesteetikas mõjutas kogu järgnenud teatriperioodi, seda on kutsutud ka eesti teatri kuldajaks. SU M M A R Y Young directors emerged in Estonian theatre at the end of the 1960s. More specifically, during the years 1969–1974 many new directors’ names appeared on theatre posters, and the fundamental changes in the language and content of the theatre at the end of the 1960s and the 1970s began to be associated with these names. Most important among these are Evald Hermaküla, Jaan Tooming, Kalju Komissarov, and Karin Raid. Within a short time these young directors changed prevailing assumptions about the purpose, means, and content of the theatre in Estonia. This phenomenon came to be referred to as the breakthrough, or the new wave; later on, in sum, as the renewal of theatre. A generational change was taking place in the theatre, and in this framework a different language of theatre emerged, which began carrying innovative emotional and aesthetic paradigms. As in the Anglo-American cultural space, this new

En algunos experimentos, el campo del espejo era paralelo al campo magnetico guia, en otros, antiparalelo, es decir, se creo un campo desviador con dos regiones de intensidad nula. Pudo comprobarse que el plasmoide inyectado (con un inyector de titanio o con uno coaxial) atraviesa con bastante facilidad el espejo magnetico cuando la direccion del campo del espejo coincide con la del campo magnetico guia, que no lo atraviesa cuando el campo es de tipo desviador. Basandose en estos experimentos, los autores demostraron la posibilidad de eliminar las impurezas pesadas de un plasma inyectado, utilizando una puerta magnetica pulsada que crea regiones en las que la intensidad del campo magnetico es nula y las lfneas.de fuerza magnetica se dirigen hacia las paredes de la camara. En los experimentos provisionales sobre compresion adiabatica del plasma en una trampa de espejo los autores observaron rayos X duros (de 30 keV de energia); investigaron la influencia ejercida por el campo magnetico inicial y los parametros del plasmoide sobre la intensidad y la dureza de estos rayos.

    -etileno se discuten en funcion de dos mecanismos de insercion previamente propuestos, a saber, la insercion del atomo de carbono en los enlaces C = C y C-H para formar compuestos de adicion C-C{sub 2}H{sub 4}. Al aumentar la concentracion de neon no desaparece ningun producto, pero los rendimientos relativos sufren modificaciones considerables. Los productos tales como el acetileno y el vinil-acetileno que pueden formarse a partir de los compuestos iniciales de adicion C-C{sub 2}H{sub 4}, en virtud de procesos que requieren gran cantidad de energia, disminuyen en importancia, mientras que aumenta el rendimiento de los productos formados por procesos que exigen poca energia, tales como los compuestos C{sub 5}. Algo semejante sucede con el etano. Los estudios por degradacion han mostrado que la distribucion intramolecular de {sup 11}C en el aleno y el metilacetileno formados a partir de etileno es afectada por el efecto moderador del neon. Ello implica la participacion de los enlaces C = C y C-H en la formacion de estos productos, asi como una relacion de dependencia entre la razon de ataque en esos dos tipos de enlace y la energia cinetica del atomo de carbono que interviene en la reaccion. Otros estudios con indicadores dobles acerca de la formacion de acetileno a partir de moleculas sencillas tales como CH{sub 2}CD{sub 2}, CH{sub 3}CH{sub 2}D, CD{sub 3}CDH{sub 2} y a partir de varias mezclas de otros alcanos y alquenos marcados indican que la perdida de energia cinetica por el atomo de carbono ejerce escaso efecto en el indice relativo de ataque en varios tipos de enlace C-H.

    . La velocidad y direccion de desplazamiento dependen de la forma de la superficie del manto y de las caracteristicas hidraulicas de las capas acuiferas portadoras. La forma del manto freatico ha sufrido una profunda modificacion debido a la evacuacion de grandes cantidades de agua. Basandose en la pendiente de las capas acuiferas y en las mediciones de su permeabilidad, se ha calculado que el desplazamiento dura por termino medio 180 anos. Se admite que la velocidad maxima puede ser varias veces superior a la media senalada. Sin embargo, el efecto de la adsorcion o de otras reacciones es disminuir considerablemente la velocidad de desplazamiento de las sustancias radiactivas, en relacion con la velocidad de las aguas. No hay indicios de que los productos de fision se esten desplazando desde los lugares de evacuacion hacia el rio.

Con los centelleogramas de intervalo dinamico muy amplio, en los que un solo nivel de corte no revela todas las regiones de interes, era preciso anteriormente trabajar a diversos niveles. Para allanar esta dificultad, los autores han tratado de emplear un elemento fotosensible bizonal que analiza una region del centelleograma situada alrededor del campo de vision del elemento principal. Este dispositivo se puede emplear, por l'o menos, de tres maneras diferentes: a) de manera ' n o rm a l' ; b) prescindiendo de la densidad general del registro y respondiendo solamente a pequenas variaciones, fijando asi su propio nivel de corte; c) indicando solamente cambios bruscos de densidad.

El hincapie que la quimica estructural hace sobre los compuestos del carbono (como lo pone de manifiesto la division de la'quimica descriptiva en las categorias e inorganica) se atribuye al hecho de ser sumamente lentas las reacciones de intercambio donde intervienen enlaces C-C o uniones entre carbono y cualquier otro atomo que no posea orbitales de enlace libres en niveles bajos (por ejemplo: Si, Ge, N, P, As, O, S, Se, F, Cl, Br). No obstante ello, hay vastos dominios de la quimica inorganica que no han podido describirse dado que las moleculas sufren reacciones de intercambio tan rapidas que resulta imposible separarlas. Sin embargo, se las puede identificar y valorar por metodos ffsicos (tales como la resonancia magnetica nuclear) con constantes de tiempo pequenas, a condicion de someter los datos obtenidos a un tratamiento matematico adecuado, siendo este tratamiento de una complejidad que justifica el empleo de una calculadora rapida [6,16]. Los topicos expuestos se ejemplifican [2, 12, 24, 28] mediante sistemas especificos seleccionados entre. los trabajos mas recientes del autor. Ademas de los estudios de equilibrio, se presta atencion a la cinetica [26, 27] de los procesos de intercambio.
