    2011-12-30

    New polyene macrolide antibiotic SJA-95 in free as well as liposomal (lip.) forms, with and without interferon-γ (IFN-γ) was studied in mice model of aspergillosis using biological and biochemical parameters viz. colony forming units (CFU) in liver, spleen, kidney, lung and brain, and serum IgG, and interleukin-4 (IL-4). Treatment with free and lip SJA-95 along with IFN-γ prolonged the survival time, reduced CFU in vital organs, decreased serum IgG and IL-4 levels. SJA-95 lip form showed greater antifungal activity as compared to free form. The combined treatment of lip SJA-95 with IFN-γ showed further enhancement in antifungal activity of SJA-95 (lip). The present experimental findings demonstrated IFN-γ might act as a potent modulator in immune reaction during fungal infection and can be a useful adjunctive in antifungal therapy in the management of deep seated systemic mycoses.

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

    PubMed

    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.

  10. B cells that simultaneously express surface IgM and IgE in Nippostrongylus brasiliensis-infected SJA/9 mice do not provide evidence for isotype switching without gene deletion.

    PubMed Central

    Katona, I M; Urban, J F; Finkelman, F D

    1985-01-01

    Recently, it has been reported that in SJA/9 mice infected with Nippostrongylus brasiliensis there are increased numbers of lymphoid cells positive for surface IgM and IgE (sIgM+ and sIgE+) even though they fail to secrete IgE, that both the sIgM and sIgE on these cells are intrinsic, and that there has been no deletion of genes for the Ig heavy chain constant region in these cells. These observations support a nondeletional model for Ig isotype switching. We have now reexamined the nature of sIgE on sIgE+ spleen and mesenteric lymph node cells of N. brasiliensis-infected SJA/9 mice, and the following observations lead us to believe that this sIgE is cytophilic rather than intrinsic: (i) Only approximately 50% of the N. brasiliensis-infected SJA/9 mice have detectable percentages of sIgE+ lymphoid cells. All mice with detectable sIgE+ lymphocytes have lymphocytes positive for intracytoplasmic IgE (cIgE+) and secrete IgE in vitro, while cIgE+ cells and IgE secretion are absent from N. brasiliensis-infected SJA/9 mice that lack sIgE+ cells. (ii) SJA/9 B lymphocytes have receptors for IgE: expression of these receptors is increased in N. brasiliensis-infected mice that have sIgE+ lymphocytes, but not in infected SJA/9 mice that lack sIgE+ lymphocytes. (iii) Treatment of sIgM+ sIgD+ sIgE+ cells for 1 min with dilute acid removes most sIgE but does not affect expression of sIgM or sIgD. (iv) The removal of mouse IgE from sIgE+ B cells facilitates the binding of exogenous rat IgE. (v) The small amount of sIgE that is reexpressed during a period of in vitro culture after acid treatment is blocked by inclusion of exogenous rat IgE in the culture medium. These observations show that most sIgM+ sIgE+ B cells in N. brasiliensis-infected SJA/9 mice do not express intrinsic sIgE; thus studies using these cells to determine mechanisms of Ig isotype switching are inconclusive.

    To explore the possibilities of a novel multiplex real-time PCR system for rapid diagnosis, genetic typing of serovars and clinical application in NGU, we developed a multiplex real-time PCR system for the simultaneous diagnosis of Chlamydia trachomatis, Ureaplasma parvum and Ureaplasma urealyticum and molecular detection of serovars of C. trachomatis and U. parvum in NGU using the SNP technology and TaqMan-LNA probe. In 57 pathogen-positive clinical specimens, we identified the following C. trachomatis serovars: D (20.05%, 12/57), E (36.84%, 21/57), F (19.30%, 11/57), G (8.77%, 5/57), H (5.26%, 3/57), J (3.51%, 2/57), and K (5.26%, 3/57). In 115 pathogen-positive clinical specimens, we identified the following U. parvum serovars: 1 (0.87%, 2/115), 3 (55.65%, 64/115), 6 (20.87%, 24/115) and 14 (21.74%, 25/115). Our fast pathogen diagnosis and serotyping assay using real-time TaqMan-LNA PCR may improve our ability to study the pathogenesis and epidemiology of NGU.

  12. Numerical Simulations of Jet Mixing Enhancement in a Round Jet Exhaust Using SJA

    NASA Astrophysics Data System (ADS)

    Hong, Liang; Zhang, Rubing; Liu, Zheng

    2017-03-01

    Symmetric synthetic jet is used to stimulate a Mach number 0.9 and high temperature jet for the mixing enhancement. The movement of the piston-type synthetic jet is simulated by dynamic mesh based on URANS numerical methods. Jet flapping, streamwise vortex and geometric axis transformation are the jet mixing mechanism. However, the jet mixing enhancement effect depends on penetration area, which consists of penetration depth and spanwise. And the penetration area is determined by actuator nozzle diameter and blowing jet momentum. In addition, a 54% reduction in potential core length and maximum 45.8K decrease in potential temperature are achieved.

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

    NASA Technical Reports Server (NTRS)

    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.

  15. A trehalose-6-phosphate synthase gene from Saccharina japonica (Laminariales, Phaeophyceae).

    PubMed

    Deng, Yunyan; Wang, Xiuliang; Guo, Hui; Duan, Delin

    2014-01-01

    The full-length cDNA sequence of a trehalose-6-phosphate synthase gene from Saccharina japonica (designated as SjaTPS) (Accession: KC578568) was isolated based on homologous cloning and RACE-PCR. It was 4,127 bp, with 320 bp 5'-UTR, 21 bp 3'-UTR, and open reading frame (ORF) of 3,786 bp. The deduced 1,261 amino acids characterized with predicted molecular weight of 137.84 kDa and theoretical isoelectric point of 7.12. The SjaTPS had one N-terminal CBM20 (family 20 carbohydrate-binding module) domain, one TPS domain (trehalose-6-phosphate synthase) in the middle region and a single TPP (trehalose-6-phosphate phosphatase) domain near the C-terminus. Structural analysis suggested that the SjaTPS putatively functioned as trehalose-6-phosphate synthase, and might be related to laminaran metabolism in S. japonica. Homology analysis indicated that the SjaTPS shared 49-70 % similarities with the 13 known TPS sequences of other algae; only 55 % amino acid similarities were detected between SjaTPS and the previously reported TPS sequence of S. japonica (Accession: DQ666325). Phylogenetic analysis revealed close affinity between SjaTPS and TPS of brown alga Ectocarpus siliculosus (Accession: CBJ29609). Transcriptional analysis showed that desiccation greatly enhanced SjaTPS expression and the maximum appeared at 3 h, which was about 300-fold compared to that of the start, implied that SjaTPS was involved with drought adaption in kelp. In vitro expression of SjaTPS showed that one distinct band existed at ~115 kDa, and western blot detection proved that it was positive to the anti-His antibody with high specificity. Our results increased the knowledge of trehalose-6-phosphate synthase properties in S. japonica and also important for better understanding the role trehalose plays in kelp abiotic tolerance for adaption to the sublittoral habitats.

  16. Numerical Study of a Novel Piston-type Synthetic Jet Actuator with a Quick-return Characteristic

    NASA Astrophysics Data System (ADS)

    Liu, Zheng; Eriqitai; Hong, Liang

    2017-03-01

    A novel designed piston-type synthetic jet actuator has been developed, which has a quick-return characteristic. When moving to the Top Dead Centre, the piston in high speed route moves faster than the classical one. Compared with classical piston-type SJA, the pressure ratio of the cavity, jet velocity and the jet momentum of the novel SJA increase significantly, which greatly enhances the performance of the actuator. A parametric study has been carried out focusing on the affection in different actuation frequencies and duty cycle. Results show that the performance of the quick-return piston-type SJA is significantly improved.

  20. [Pathogen spectrum of non-gonorrhea urethritis].

    PubMed

    Schmidt, U; Hartmann, M; Pfützner, H

    1988-05-01

    By cultural investigations in 333 males with non-gonorrhoical urethritis (NGU) and 158 control probands it was demonstrated that Chlamydia trachomatis is the main germ of this disease also in the GDR with a frequency of 40% of the cases. A chlamydia-negative NGU was caused in 15% by Ureaplasma urealyticum in a number of greater than or equal to 10(4) germs/ml urine and in 5% by Trichomonas vaginalis, respectively. Candida albicans occurred significant more frequently in the patient group (21%) than in the control group (4%). Other optional pathogenic bacterias were the cause of NGU in single cases. The diagnosis and therapy of NGU should be considered this germ spectrum and the sexual partner also.

    2015-01-01

    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 <28 years of age (OR=5.4, 95% CI 1.3 to 22.2). U parvum was detected in 14% (17/119) cases and 31% (36/117 controls) and thus was negatively associated with NGU (aOR=0.4, 95% CI 0.2 to 0.8). The prevalence of U urealyticum (16%) in controls was higher than that of C trachomatis (3.4%) or M genitalium (4.3%, p<0.05, each comparison). Conclusions Unlike U parvum, U urealyticum was associated with 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

    2016-06-23

    This study was conducted to determine the efficiency of different tsetse traps in 28 sites across Tanzania. The traps used were biconical, H, NGU, NZI, pyramidal, S3, mobile, and sticky panels. Stationary traps were deployed at a distance of 200 m apart and examined 72 h after deployment. The results showed that 117 (52.2%) out of the 224 traps deployed captured at least one Glossina species. A total of five Glossina species were captured, namely Glossina brevipalpis, Glossina pallidipes, Glossina swynnertoni, Glossina morsitans, and Glossina fuscipes martinii. Biconical traps caught tsetse flies in 27 sites, pyramidal in 26, sticky panel in 20, mobile in 19, S3 in 15, NGU in 7, H in 2 and NZI in 1. A total of 21 107 tsetse flies were trapped, with the most abundant species being G. swynnertoni (55.9%), followed by G. pallidipes (31.1%), G. fuscipes martinii (6.9%) and G. morsitans (6.0%). The least caught was G. brevipalpis (0.2%). The highest number of flies were caught by NGU traps (32.5%), followed by sticky panel (16%), mobile (15.4%), pyramidal (13.0%), biconical (11.3%) and S3 (10.2%). NZI traps managed to catch 0.9% of the total flies and H traps 0.7%. From this study, it can be concluded that the most efficient trap was NGU, followed by sticky panel and mobile, in that order. Therefore, for tsetse fly control programmes, NGU traps could be the better choice. Conversely, of the stationary traps, pyramidal and biconical traps captured tsetse flies in the majority of sites, covering all three ecosystems better than any other traps; therefore, they would be suitable for scouting for tsetse infestation in any given area, thus sparing the costs of making traps for each specific Glossina species.

    The idea of having a device that is capable of working in a systematic process allowing control of the boundary layer by means of operated on high-frequency, small-scale, and low energy actuators has caught the interest of the aerodynamicist community. With an eye on the available data and potential flow control advantages, our research team set out to manufacture a compact SJA (Synthetic Jet Actuator) of its own, which would be capable of being installed inside an airfoil. It consists of components such as a single piston cylinder, with variable exit geometry along with the control system that has an electrical actuator which can be regulated in order for it to be capable of producing various operating frequencies. This paper consists of a study into the design of a single piston device SJA and will present all significant data both theoretical and computational regarding its design and performance.

    The roles of IgE and mast cells on expulsion of adult Hymenolepis nana from the intestine were examined in mice. IgE-dependency was determined by comparing congenitally IgE-deficient SJA/9 and IgE-producing SJL/J mice infected with 50 H. nana eggs. Anti-H. nana IgE antibody was detected at three weeks post infection (p.i.) in SJL but not in SJA mice. The number of adult worms in the intestines of SJA and of SJL mice were similar at two weeks, but significantly more were found in SJA mice at three weeks p.i. Treatment of mice with anti-epsilon antibody also resulted in an increased worm burden at three weeks, suggesting participation of IgE in expulsion of H. nana. Intestinal mastocytosis was induced by infection regardless of the IgE status of the mice. Mast cell-dependency was tested in mast cell-deficient W/Wv and in normal littermate +/+ mice infected with 100 H. nana eggs. Anti-H. nana antibody was detected in both groups of mice at three weeks p.i. Worm expulsion seemed to be mast cell dependent because expulsion was less complete in W/Wv mice at three weeks p.i. Peripheral blood eosinophilia was comparable at three weeks p.i. in both IgE and mast cell sufficient and deficient mice. These results suggest that IgE and mast cells participate in the expulsion of H. nana adults from intestine in mice.

    Although the zebrafish (Danio rerio) has been widely utilized as a model organism for several decades, there is little information available on physiological variation underlying genetic variation among the most commonly used inbred strains. This study evaluated growth performance using physiological and molecular markers of growth in response to fasting in six commonly used zebrafish strains [AB, TU, TL, SJA, WIK, and petstore (PET) zebrafish]. Fasting resulted in a standard decrease in whole blood glucose levels, a typical vertebrate glucose metabolism pattern, in AB, PET, TL, and TU zebrafish strains. Alternatively, fasting did not affect glucose levels in SJA and WIK zebrafish strains. Similarly, fasting had no effect on myostatin mRNA levels in AB, PET, TU, and WIK zebrafish strains, but decreased myostatin-1 and -2 mRNA levels in SJA zebrafish. Consistent with previous work, fasting increased myostatin-2 mRNA levels in TL zebrafish. These data demonstrate that variation is present in growth performance between commonly used inbred strains of zebrafish. These data can help future research endeavors by highlighting the attributes of each strain with regard to growth performance so that the most fitting strain may be utilized.

    Sophoragrin, a mannose/glucose-specific lectin in Sophora japonica (Japanese pagoda tree) bark, was the first lectin found to show self-aggregation that is dependent on the sugar concentration accompanying the interconversion between solubility and insolubility [Ueno, Ogawa, Matsumoto and Seno (1991) J. Biol. Chem. 266, 3146-3153]. The interconversion is regulated by the concentrations of Ca(2+) and specific sugars: mannose, glucose or sucrose. The specific glycotopes for sophoragrin were found in the sophoragrin subunit and an endogenous galactose-specific lectin, B-SJA-I (bark S. japonica agglutinin I), and the lectin subunit that binds to the glycotope was identified by photoaffinity glycan probes. Remarkably, the insoluble polymer of sophoragrin is dissociated by interaction with B-SJA-I into various soluble complexes. Based on these results, self-aggregation of sophoragrin was shown to be a unique homopolymerization due to the sugar-specific interaction. An immunostaining study indicated that sophoragrin localizes mainly in vacuoles of parenchymal cells coincidently with B-SJA-I. These results indicate that sophoragrin can sequester endogenous glycoprotein ligands via sugar-specific interactions, thus providing new insights into the occurrence and significance of the intravacuolar interaction shown by a legume lectin.

    High strain rate and high temperature response of three types of aluminum based particulate metal matrix ceramic composites is investigated by performing split Hopkinson pressure bar (SHPB) experiments. The composites are: NGP-2014 (15% SiC), NGT-6061 (15% SiC), and NGU-6061 (15% Al2O3), in which all the reinforcement materials are percentage by volume. Johnson-Cook constitutive model constants are evaluated from the high strain rate/high temperature data and implemented in a two dimensional finite element computer code (EPIC-2D) to simulate the penetration of an ogive nose tungsten projectile (23 grams) at a velocity 1.17 km/sec into the base 6061-T6 aluminum alloy and the composite NGU-6061. The simulated penetrations in the composite and in 6061-T6 aluminum agree with in 2%, in both materials, with the measured values.

    Geology and all geological structures are three-dimensional in space. GIS and databases are common tools used by geologists to interpret and communicate geological data. The NGU (Geological Survey of Norway) is the national institution for the study of bedrock, mineral resources, surficial deposits and groundwater and marine geology. 3D geology is usually described by geological profiles, or vertical sections through a map, where you can look at the rock structure below the surface. The goal is to gradually expand the usability of existing and new geological profiles to make them more available in the retail applications as well as build easier entry and registration of profiles. The project target is to develop the methodology for acquisition of data, modification and use of data and its further presentation on the web by creating a user-interface directly linked to NGU's webpage. This will allow users to visualise profiles in a 3D model.

    Although up to about half the cases of acute non-gonococcal urethritis (NGU) are caused by Chlamydia trachomatis organisms (chlamydiae) and a smaller, ill-defined, proportion probably by Ureaplasma urealyticum organisms (ureaplasmas), the aetiology of all cases is not understood. Clarification of the role of the anaerobe, Bacteroides ureolyticus, was sought in the current study. Seventy five chlamydia negative patients with NGU were treated on a double blind placebo controlled basis with metronidazole. After seven days more of the 35 patients given this drug tended to improve clinically than the 40 given the placebo, but the difference was not significant. Of 23 chlamydia negative but anaerobe positive men, however, 78% (7/9) receiving metronidazole responded clinically, but only 7% (1/14) receiving placebo responded (p less than 0.001). Furthermore, whereas 78% of the anaerobe positive men given metronidazole recovered, only 23% (6/26) of the anaerobe negative men did so (p less than 0.02). No further evidence for the role of ureaplasmas in the aetiology of NGU was obtained, but the data suggest that B ureolyticus organisms, and perhaps other anaerobes, have an important role in a small proportion of cases and that the beneficial effects of metronidazole given on an empirical basis will be confined to anaerobe positive urethritis.

  16. Development of high-power, compact synthetic jet actuators for flow separation control

    NASA Astrophysics Data System (ADS)

    Gilarranz Runge, Jose Luis

    This work presents the development of high-power, compact synthetic jet actuators (SJA) for flow separation control. The developed actuator is compact enough to fit in the interior of a NACA0015 profiled wing with a chord of 0.375 in. Test bench experiments showed that the multi-piston actuator array was capable of producing exit velocities of up to 90 m/s for an actuator frequency of 130 Hz. The actuator was placed in a NACA 0015 wing and tested in a wind tunnel. An experimental investigation into the effects of a synthetic jet actuator on the performance of the wing is described. Emphasis is placed on the capabilities of the actuator to control the separation of the flow over the wing at high angles of attack. The investigation included the use of force balance measurements, on-surface flow visualization with oil and tufts, off-surface flow visualizations with smoke, surface pressure distribution measurements and wake surveys. In addition to flow separation control data, results corresponding to hot wire measurements at the exit of the slot, are also presented and are used for the characterization of the flowfield generated by the synthetic jet actuators. Most of the tests were performed at a freestream velocity of 35 m/s, corresponding to a Reynolds number of 8.96 x 105. The angle of attack was varied from -2.0 to 29 degrees. For the tests presented here, at angles of attack lower than 10 degrees the actuator tends to increase the lift curve slope as the actuation frequency is increased. At higher angles of attack, the SJA extends the range of angle of attack for which the wing may be operated without stalling. The use of the actuator causes an 80% increase in the value of maximum lift coefficient, and the angle at which stall occurs is increased from 12 to 18 degrees (for the Reynolds number range of the test). The drag on the wing is decreased as a consequence of SJA actuation. This was verified with the force balance measurements and by analysis of the wake

    2014-01-01

    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.

    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

    OBJECTIVES--To evaluate gonococcal (GU) and nongonococcal urethritis (NGU), chlamydia antigen, and serostatus for syphilis and human immunodeficiency virus (HIV) among males attending a Malawian STD clinic with complaints of urethral discharge and/or dysuria. To collect demographic and behavioural data and to determine the effectiveness of five treatments for urethritis. METHODS--Urethritis was diagnosed using microscopy and culture for Neisseria gonorrhoeae. Sera were screened with rapid plasma reagin (RPR) and if reactive, with microhaemagglutination for Treponema pallidum (MHA-TP). HIV antibodies and chlamydia antigen were detected using enzyme immunoassay. Patients were randomised for treatment, cure was assessed 8-10 days later. RESULTS--At enrolment, GU was diagnosed in 415 (80.3%) and NGU in 59 (11.2%) of 517 males. Chlamydia antigen was found in 26 (5.2%) of 497 specimens tested. Syphilis seropositivity rate (RPR and MHA-TP reactive) was 10.7%. Overall HIV seroprevalence was 44.2%; 71.7% of men with reactive syphilis serology were HIV(+) compared with 40.9% of syphilis seronegatives (OR: 3.6, p < 0.001). Trimethoprim 320 mg/sulphamethoxazole 1600 mg by mouth for 2 days (TMPSMX), or the combination of amoxicillin 3 gm, probenicid 1 gm, and clavulanate 125 mg by mouth once (APC), failed to cure gonorrhoea effectively. Amoxicillin 3 gm, probenicid 1 gm, and clavulanate 125 mg, by mouth once with doxycycline 100 mg BID for 7 days (APC-D), gentamicin 240 mg IM once (GENT), ciprofloxacin 250 mg by mouth once (CIPRO) cured 92.9% to 95% of gonorrhoea. APC-D treatment did not generate less NGU at follow-up. HIV serostatus did not affect cure of urethritis. CONCLUSION--All patients presenting with urethritis should be treated syndromically using a simple algorithm and screened for syphilis seroreactivity for appropriate treatment and counselling.

    The localization of carbohydrate terminals in Kudoa septempunctata ST3-infected muscle of olive flounder (Paralichthys olivaceus) was investigated using lectin histochemistry to determine the types of carbohydrate sugar residues expressed in Kudoa spores. Twenty-one lectins were examined, i.e., N-acetylglucosamine (s-WGA, WGA, DSL-II, DSL, LEL, STL), mannose (Con A, LCA, PSA), galactose/N-acetylgalactosamine (RCA12, BSL-I, VVA, DBA, SBA, SJA, Jacalin, PNA, ECL), complex type N-glycans (PHA-E and PHA-L), and fucose (UEA-I). Spores encased by a plasmodial membrane were labeled for the majority of these lectins, with the exception of LCA, PSA, PNA, and PHA-L. Four lectins (RCA 120, BSL-I, DBA, and SJA) belonging to the galactose/N-acetylgalactosamine group, only labeled spores, but not the plasmodial membrane. This is the first confirmation that various sugar residues are present in spores and plasmodial membranes of K. septempunctata ST3. PMID:27169676

    Mycoplasma genitalium is a member of genital mycoplasmas, which is emerging as an important causative agent of sexually transmitted infections both in males and females. The advent of polymerase chain reaction and other molecular methods have made studies on M. genitalium more feasible, which is otherwise a difficult organism to isolate. Besides Chlamydia trachomatis, M. genitalium is now an important and established cause of non gonococcal urethritis (NGU) in men, more so in persistent and recurrent NGU. Multiple studies have also shown a positive association of M. genitalium with mucopurulent cervicitis and vaginal discharge in females as well. The evidences for M. genitalium pelvic inflammatory diseases and infertility are quite convincing and indicate that this organism has potential to cause ascending infection. Lack of clear association with M. genitalium has been reported for bacterial vaginosis and adverse pregnancy outcomes. Diagnosis of M. genitalium infections is performed exclusively using nucleic acid amplification tests (NAATs), owing to poor or slow growth of bacterium in culture. Although there are no guidelines available regarding treatment, macrolide group of antimicrobials appear to be more effective than tetracyclines. The present review provides an overview of the epidemiology, pathogenesis, clinical presentation and management of sexually transmitted infections due to M. genitalium. PMID:23391789

    Conventional carbohydrate histochemistry and the binding patterns of 21 lectins were analysed to characterise the glycoconjugate content in the components of the vomeronasal organ of the armadillo Chaetophractus villosus. The mucomicrovillous complex of the sensory epithelium bound most of the lectins studied. No reaction was observed with Con A, PSA, S-Con A and SBA, and the sustentacular cells were stained with UEA-I, DSL, LEL, STL and Con A. The vomeronasal receptor neurons were labelled with S-WGA, WGA, PNA, UEA-I, STL, Con A, S-Con A, ECL and RCA120. The basal cell layer reacted with S-WGA, WGA, LCA, UEA-I, DSL, LEL, STL, Con A, JAC and VVA. The nonsensory epithelium exhibited a differential staining in relation to the different components. The mucociliary complex stained with ECL, DBA, JAC, RCA120, STL, LCA, PHA-E, PHA-L, LEL, BSL-I and VVA. However, SJA and UEA-I stained the mucus complex lining a subpopulation of columnar cells. The cytoplasm and cell membranes of columnar cells was labelled with DBA, DSL and LCA. The apical region of these cells exhibited moderate reactivity with LEL and SJA. None of the lectins bound specifically to secretory granules of the nonsecretory cells. Basal cells of the nonsensory epithelium were labelled with DSL, LEL, LCA, BSL-I and STL. The vomeronasal glands showed a positive reaction with WGA, DSL, LEL, LCA, DBA, PNA, RCA120 and SBA. Subpopulations of acinar cells were observed with ECL, S-WGA, Con A, S-Con A and DBA. PNA and RCA120 stained the cells lining the glandular ducts. In comparison with previous results obtained in the olfactory mucosa of the same group of armadillos, the carbohydrate composition of the vomeronasal organ sensory epithelium differed from the olfactory sensory epithelium. This is probably related to the different nature of molecules involved in the perireceptor processes. PMID:10853958

By constructing suitable auxiliary functions and using a first-order differential inequality technique, we establish the conditions on the nonlinearities and data to ensure that the solution u( x, t) blows up at some finite time. Moreover, the upper and lower bounds for the blow-up time, when blow-up does occur, are obtained.

    Mycoplasma genitalium is a cause of non-gonoccocal urethritis (NGU) in men and cervicitis and pelvic inflammatory disease in women. Recent international data also indicated that the first line treatment, 1 gram stat azithromycin therapy, for M. genitalium is becoming less effective, with the corresponding emergence of macrolide resistant strains. Increasing failure rates of azithromycin for M. genitalium has significant implications for the presumptive treatment of NGU and international clinical treatment guidelines. Assays able to predict macrolide resistance along with detection of M. genitalium will be useful to enable appropriate selection of antimicrobials to which the organism is susceptible and facilitate high levels of rapid cure. One such assay recently developed is the MG 23S assay, which employs novel PlexZyme™ and PlexPrime™ technology. It is a multiplex assay for detection of M. genitalium and 5 mutations associated with macrolide resistance. The assay was evaluated in 400 samples from 254 (186 males and 68 females) consecutively infected participants, undergoing tests of cure. Using the MG 23S assay, 83% (331/440) of samples were positive, with 56% of positives carrying a macrolide resistance mutation. Comparison of the MG 23S assay to a reference qPCR method for M. genitalium detection and high resolution melt analysis (HRMA) and sequencing for detection of macrolide resistance mutations, resulted in a sensitivity and specificity for M. genitalium detection and for macrolide resistance of 99.1/98.5% and 97.4/100%, respectively. The MG 23S assay provides a considerable advantage in clinical settings through combined diagnosis and detection of macrolide resistance. PMID:27271704

    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.

  14. Integrated actuation and energy harvesting in prestressed piezoelectric synthetic jets

    NASA Astrophysics Data System (ADS)

    Mane, Poorna

    With the looming energy crisis compounded by the global economic downturn there is an urgent need to increase energy efficiency and to discover new energy sources. An approach to solve this problem is to improve the efficiency of aerodynamic vehicles by using active flow control tools such as synthetic jet actuators. These devices are able to reduce fuel consumption and streamlined vehicle design by reducing drag and weight, and increasing maneuverability. Hence, the main goal of this dissertation is to study factors that affect the efficiency of synthetic jets by incorporating energy harvesting into actuator design using prestressed piezoelectric composites. Four state-of-the-art piezoelectric composites were chosen as active diaphragms in synthetic jet actuators. These composites not only overcome the inherent brittle and fragile nature of piezoelectric materials but also enhance domain movement which in turn enhances intrinsic contributions. With these varying characteristics among different types of composites, the intricacies of the synthetic jet design and its implementation increases. In addition the electrical power requirements of piezoelectric materials make the new SJA system a coupled multiphysics problem involving electro-mechanical and structural-fluid interactions. Due to the nature of this system, a design of experiments approach, a method of combining experiments and statistics, is utilized. Geometric and electro-mechanical factors are investigated using a fractional factorial design with peak synthetic jet velocity as a response variable. Furthermore, energy generated by the system oscillations is harvested with a prestressed composite and a piezo-polymer. Using response surface methodology the process is optimized under different temperatures and pressures to simulate harsh environmental conditions. Results of the fractional factorial experimental design showed that cavity dimensions and type of signal used to drive the synthetic jet actuator

    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

    NASA's Space Technology 8 project (ST-8) is subsystem demonstration which will validate four technologies that have been identified as necessary to enable future NASA space science missions. NASA's New Millennium Program, with input from the science community, identified the following four technologies: Miniature Loop Heat Pipe with Multiple Evaporators Thermal Management System (MLHP), Scalable Architecture for the Investigation of the Load Managing Attributes of a Slender Truss (SAILMAST), Next Generation UltraFlex (NGU), and Environmentally Adaptive Fault Tolerant Computing (EAFTC). Once validated on a deep space mission, these technologies will be available for use on future science missions. Examples of previous enabling technologies demonstrated by NMP are the ion engines on Deep Space 1 and the Autonomous Sciencecraft Experiment demonstrated by ST6. The MLHP, provided by NASA's Goddard Space Flight Center will demonstrate that a loop heat pipe with multiple evaporators and condensers can transport large heat loads over long distances without external pumping. It is expected that this technology will enable more precise temperature control decreasing the mass, power, and volume of small remote sensing and surface-based spacecraft. The SAILMAST experiment is a deployable gossamer mast technology, which will validate its load-carrying characteristics by correlating in-flight measurements with analytical predictions. It will enable a new class of missions, which employ solar sail propulsion technology. The NGU will demonstrate the next generation in ultra-lightweight fan-folded flexible solar arrays, providing ultra-high specific power (170-220 W/kg BOL), ultra-compact stowage volume (>33 W/m3), and high deployed stiffness. The result is less mass and volume needed for power generation on future spacecraft. The EAFTC will integrate commercial-off-the-shelf (COTS) processing components and fault-tolerant control algorithms to provide an adaptable, high

    2015-07-29

    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

    This study aimed to evaluate the ability of a panel of lectins to inhibit the ability of Pasteurella multocida to adhere to and affect the rabbit respiratory epithelium. Nasal septa from rabbit fetuses were cultured with various lectins before the addition of P. multocida. The percentage of bacteria adhering to the epithelium was evaluated semiquantitatively by indirect immunoperoxidase (IIP) staining. The goblet cells (GCs) were counted in semithin sections stained with toluidine blue and served as the main morphological criterion to evaluate the inhibitory effect of the lectins. The lectins PNA, WGA, RCA120, and DBA significantly inhibited the adhesion of P. multocida to the ciliated epithelium (P < 0.05) and prevented the pathogen-induced increase in the number of GCs (P < 0.05) compared with those of positive control tissues. In addition, VVA, SJA, UEA I, DSL, SBA, and ECL significantly inhibited the increase in GCs compared with that of the control tissues. The results suggest that less aggressive therapeutic strategies, such as treatment with lectins, may represent alternative approaches to control bacterial respiratory infections. PMID:25810949

    Aiming at learning the association between the gut microbiota and termites with different diet habits and phylogenetic positions, the gut bacteria of three populations for each of the two higher termites (wood-feeding Mironasutitermes shangchengensis and fungus-feeding Odontotermes formosanus) and two wood-feeding lower termites (Tsaitermes ampliceps and Reticulitermes flaviceps) were analyzed by high-throughput 454 pyrosequencing of 16S V1-V3 amplicons. As results, 132 bacterial genera and some unidentified operational taxonomic units within 29 phyla in the gut bacteria were detected, with Spirochaetes (11-55%), Firmicutes (7-18%), Bacteroidetes (7-31%), and Proteobacteria (8-14%) as the main phyla, and Treponema, TG5, Dysgonomonas, Tannerella, za29, Lactococcus, Pseudomonas, and SJA-88 as the common genera in all the four termites. The diversity of gut bacterial communities in the higher termite guts was significantly greater than that in the lower termites; while the gut microbiota in M. shangchengensis (wood-feeding higher termite) was more similar to those of the wood-feeding lower termites rather than that of O. formosanus (fungus-feeding higher termite), and phylum Spirochaetes and nitrogen-fixing bacteria were super-dominant in the wood-feeding termites, despite of their phylogenetic relations. This study reported for the first time the gut bacterial communities for the termites of M. shangchengensis and T. ampliceps and the comparative analyses showed that the gut microbial communities varied according to the phylogeny and the diet habits of termites.

    Conventional histochemistry and the binding patterns of 22 biotinylated lectins were examined for characterisation of glycoconjugates in the components of the olfactory mucosa of the armadillo Chaetophractus villosus. The mucous lining the olfactory epithelium showed binding sites for DSL, WGA, STL, LEL, PHA-E and JAC. Only the basilar processes of the supporting cells stained for Con-A and S-Con A. The olfactory receptor neurons stained with LEL, LCA, Con A, S-Con A, JAC and PNA. The layer of basal cells did not react with any of the lectins studied. Bowman's glands in the lamina propria showed subpopulations of acinar cells reacting with SBA, S-WGA, WGA, STL, Con A, PSA, PNA, SJA, VVA, JAC and S-Con A, but in our optical studies with lectins we were unable to differentiate between mucous and serous cells in the way that is possible on electron microscopy. The ducts of Bowman's glands were labelled with S-WGA, STL, LEL, PHA-E, BSL-I and JAC. This histochemical study on the glycoconjugates of the olfactory mucosa in the order Xenarthra provides a basis for further experimental investigations. PMID:10386777

    The incidence of hepatocellular carcinoma (HCC) is closely correlated with hepatitis B virus (HBV)-induced liver cirrhosis. Structural changes in the glycans of serum and tissue proteins are reliable indicators of liver damage. However, little is known about the alteration of liver glycopatterns during cirrhosis and tumor progression induced by HBV infection. This study compared the differential expression of liver glycopatterns in 7 sets of normal pericarcinomatous tissues (PCTs), cirrhotic, and tumor tissues from patients with liver cirrhosis and HCC induced by HBV using lectin microarrays. Fluorescence-based lectin histochemistry and lectin blotting were further utilized to validate and assess the expression and distribution of certain glycans in 9 sets of corresponding liver tissue sections. Eight lectins (e.g., Jacalin and AAL) revealed significant difference in cirrhotic tissues versus PCTs. Eleven lectins (e.g., EEL and SJA) showed significant alteration during cirrhotic and tumor progression. The expression of Galα1-3(Fucα1-2)Gal (EEL) and fucosyltransferase 1 was mainly increasing in the cytoplasm of hepatocytes during PCTs-cirrhotic-tumor tissues progression, while the expression of T antigen (ACA and PNA) was decreased sharply in cytoplasm of tumor hepatocytes. Understanding the precision alteration of liver glycopatterns related to the development of hepatitis, cirrhosis, and tumor induced by HBV infection may help elucidate the molecular mechanisms underlying the progression of chronic liver diseases and develop new antineoplastic therapeutic strategies.

    The eco-friendly synthesis and application of Fe nanoparticles (Fe NPs) with higher activity and stability has aroused wide attention in the field of pollutant remediation. In this work, 15 plants extracts were selected for the plant-mediated synthesis of Fe NPs. The as-synthesized particles' morphology and structure were characterized by transmission electron microscopy, X-ray diffraction and UV-Vis spectroscopy. The contents of four main active biomolecules in the 15 extracts were determined, and comparative studies were further carried out to clarify the key component closely related to the reducing capacity. The results demonstrate that polyphenol is the leading ingredient involved in the biosynthesis of Fe NPs. Then Fe products synthesized by three extracts with distinct content of polyphenol were employed to remove Cr (VI) in the aqueous solution, indicating that the activity of the Fe NPs for Cr (VI) removal is consistent with the reducing capacity of the extracts. Furthermore, the Fe NPs synthesized by S. jambos(L.) Alston extract (SJA-Fe NPs) showed significant removal capacity of Cr(VI) with 698.6 mg Cr(VI) per g of iron.

    Here we demonstrate that photosynthetic oxygen production under light/dark, feast/famine cycles with no mechanical aeration and negligible oxygen diffusion is able to maintain phosphorus cycling activity associated with the enrichment of polyphosphate accumulating organisms (PAOs). We investigate the ecology of this novel system by conducting a time series analysis of prokaryotic and eukaryotic biodiversity using the V3-V4 and V4 region of the 16S and 18S rRNA gene sequences, respectively. In the Eukaryotic community, the initial dominant alga observed was Desmodesmus. During operation, the algal community became a more diverse consortium of Desmodesmus, Parachlorella, Characiopodium and Bacillariophytina. In the Prokaryotic community, there was an initial enrichment of the PAO Candidatus Accumulibacter phosphatis (Accumulibacter) Acc-SG2, and the dominant ammonia-oxidizing organism was Nitrosomonas oligotropha, however these populations decreased in relative abundance, becoming dominated by Accumulibacter Acc-SG3 and Nitrosomonas ureae. Furthermore, functional guilds that were not abundant initially became enriched including the putative Cyanobacterial PAOs Obscuribacterales and Leptolyngbya, and the H2-oxidizing denitrifying autotroph Sulfuritalea. After a month of operation, the most abundant prokaryote belonged to an uncharacterized clade of Chlorobi classified as Chlorobiales;SJA-28 Clade III, the first reported enrichment of this lineage. This experiment represents the first investigation into the ecological interactions and community assembly during photosynthetic feast/famine conditions. Our findings suggest that photosynthesis may provide sufficient oxygen to drive polyphosphate cycling.

    Multiple sclerosis (MS) is a T cell-mediated autoimmune disease of the CNS, possessing both immune and neurodegenerative events that lead to disability. Adoptive transfer (AT) of myelin basic protein (MBP)-specific T cells into naïve female SJL/J mice results in a relapsing-remitting (RR) form of experimental autoimmune encephalomyelitis (EAE). Blocking the mechanisms by which MBP-specific T cells are activated before AT may help characterize the immune arm of MS and offer novel targets for therapy. One such target is calpain, which is involved in activation of T cells, migration of immune cells into the CNS, degradation of axonal and myelin proteins, and neuronal apoptosis. Thus, the hypothesis that inhibiting calpain in MBP-specific T cells would diminish their encephalitogenicity in RR-EAE mice was tested. Incubating MBP-specific T cells with the calpain inhibitor SJA6017 before AT markedly suppressed the ability of these T cells to induce clinical symptoms of RR-EAE. These reductions correlated with decreases in demyelination, inflammation, axonal damage, and loss of oligodendrocytes and neurons. Also, calpain:calpastatin ratio, production of tBid, and Bax:Bcl-2 ratio, and activities of calpain and caspases, and internucleosomal DNA fragmentation were attenuated. Thus, these data suggest calpain as a promising target for treating EAE and MS. PMID:19627443

    Tritrichomonas foetus (T. foetus) is the causal agent of bovine tritrichomonosis (BT), a venereal disease that causes significant economic losses in the bovine livestock industry. The structural organization of T. foetus presents a cell membrane, an undulating membrane which extends along the parasite, three anterior flagella and a recurrent posterior flagellum. The interaction between the superficial glycoconjugates of the parasite and the host cell is one of the most relevant pathogenic mechanisms. In the present study, we analyzed the saccharide pattern through lectincytochemistry of the cell membrane, undulating membrane, cytoplasm and flagella of 28 isolates of T. foetus. Lectins that labeled most of the isolates were WGA, Con-A, RCA-I, LCA, GS-II and PHA-E showing the presence of D-mannose, D-glucose, N-acetylglucosamine and sialic acid. On the other hand, no labeling was observed in any of the structures with VVA, STA, LEA, Jacalin, GS-I, SJA, PHA-L, DSA, and weak labeling was observed with DBA, PNA, SBA and UEA I, showing therefore a low expression of N-acetylgalactosamine, L-fucose and galactose. In addition, GS II labeled in a granular pattern when lectincytochemistry was positive, whereas LCA strongly labeled the membranes and weakly the cytoplasms. The labeling variations observed among the isolates analyzed in the present work, could be related to differences in the pathogenic behavior of the isolates.

    The Western Forest Complex (WEFCOM) of Thailand is comprised of many protected areas and has one of the highest wildlife populations in the country. Populations of wildlife in the WEFCOM have decreased dramatically over recent years. Rapid economic development has resulted in the conversion of forest into agricultural and pastoral land, which has directly and indirectly impacted the wildlife community. This research aimed to evaluate populations of domesticated cattle (Bos indicus) and buffalo (Bubalus bubalis) in the WEFCOM and their possible impacts on the wildlife community. Domesticated cattle and buffalo keepers from 1561 (or 3.3%) of houses in and near WEFCOM were interviewed. The average number of animals per household was 15.6 cattle and 8.5 buffalo. Most villagers released domesticated cattle and buffalo to forage in the protected areas. This tended to have a high impact on the wildlife community in Huai Kha Khaeng Wildlife Sanctuary and Tungyai Naresuan Wildlife Sanctuary. The least impacted areas were Luam Khlong Ngu National Park, Thong Pha Phum National Park and Chaleam Ratanakosin National Park. With a high risk to the wildlife community, law enforcement should be used in combination with a certain level of co-management with local communities.

    An enzyme immunoassay (EIA) in parallel with cell culture was used to investigate the extent of infections due to Chlamydia trachomatis. EIA reactive confirmed in cell culture was taken as positive. C. trachomatis was found in 6 (26.0%) of 23 men with symptomatic non-gonococcal urethritis (NGU), ten (17.2%) of 58 symptom-free males and in three of 4 with postgonococcal urethritis. Among 106 asymptomatic pregnant women studied the incidence of C. trachomatis was 8.5% while a higher incidence (16.7%) was found in those with symptoms. C. trachomatis positivity in asymptomatic and symptomatic post-natal screening were 11.4% and 7.7%. Of 43 symptomatic non-pregnant females investigated, 7 (16.3%) were found to be positive for C. trachomatis. Of 3 women with PID, 2 (66.7%) harboured C. trachomatis in their cervix while in another 29 infertile women, C. trachomatis was positive in 3 (8.1%). Contraceptives appeared to have an effect on the chlamydial positivity. Comparative testing of EIA with the standard cell culture method in this study indicate EIA as a suitable alternative for the definitive diagnosis of chlamydial infection in high prevalence settings and with caution in low prevalence settings.

    Today's paleomagnetic and magnetic proxy studies involve processing of large sample collections while simultaneously demanding high quality data and high reproducibility. Here we describe a fully automated interface based on a commercial horizontal pass-through "2G" DC-SQUID magnetometer. This system is operational at the universities of Bremen (Germany) and Utrecht (Netherlands) since 1998 and 2006, respectively, while a system is currently being built at NGU Trondheim (Norway). The magnetometers are equipped with "in-line" alternating field (AF) demagnetization, a direct-current bias field coil along the coaxial AF demagnetization coil for the acquisition of anhysteretic remanent magnetization (ARM) and a long pulse-field coil for the acquisition of isothermal remanent magnetization (IRM). Samples are contained in dedicated low magnetization perspex holders that are manipulated by a pneumatic pick-and-place-unit. Upon desire samples can be measured in several positions considerably enhancing data quality in particular for magnetically weak samples. In the Bremen system, the peak of the IRM pulse fields is actively measured which reduces the discrepancy between the set field and the field that is actually applied. Techniques for quantifying and removing gyroremanent overprints and for measuring the viscosity of IRM further extend the range of applications of the system. Typically c. 300 paleomagnetic samples can be AF demagnetized per week (15 levels) in the three-position protocol. The versatility of the system is illustrated by several examples of paleomagnetic and rock magnetic data processing.

    Background Recent years, morbidity of chronic prostatis is increasing in Mongolia. Most common cause of the chronic prostatis is Non-Gonococcal Urethritis (NGU) such as chlamydia trachomatis, mycoplasma hominis, mycoplasma genitalium, ureaplasma urealyticum and ureaplasma parvum or mixed infections. Purpose The purpose of the study was to research possible relationships between signs or symptoms of the chronic prostatitis and its cause. Method A total of 466 males who have possible signs of chronic prostatitis were enrolled in the study. All patients were checked for urinalysis and expressed prostate secretion (EPS) and Polymerase Chain Reaction (PCR) of EPS detection for neisser a gonorrhea, chlamydia trachomatis, mycoplasma hominis, mycoplasma genitalium, ureaplasma urealyticum and ureaplasma parvum at an outpatient center of andrology office, Ulaanbaatar, Mongolia. Results Two hundred and eighty three of all participants have positive PCR results. Mean age of in our study was 33.1±8 years. U. realyticum was the most common (48.6%), followed by M. hominis and C. trachomatis mixed infection. In Mach, April and August were highest episodes of morbidity were registered 16.2%, 11.69% and 10.71%. Chronic pelvic pain syndrome and lower urinary tract symptoms were the most common complaints of main reason to visit outpatient clinic. Conclusions U. urealyticum was most common infection detected by PCR analyses among men who have chronic prostatitis, who have chronic pelvic pain syndrome. Further research is needed to determine if there are associations between signs or symptoms and cause of the chronic prostatis.

    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.

    Aiming at learning the association between the gut microbiota and termites with different diet habits and phylogenetic positions, the gut bacteria of three populations for each of the two higher termites (wood-feeding Mironasutitermes shangchengensis and fungus-feeding Odontotermes formosanus) and two wood-feeding lower termites (Tsaitermes ampliceps and Reticulitermes flaviceps) were analyzed by high-throughput 454 pyrosequencing of 16S V1–V3 amplicons. As results, 132 bacterial genera and some unidentified operational taxonomic units within 29 phyla in the gut bacteria were detected, with Spirochaetes (11–55%), Firmicutes (7–18%), Bacteroidetes (7–31%), and Proteobacteria (8–14%) as the main phyla, and Treponema, TG5, Dysgonomonas, Tannerella, za29, Lactococcus, Pseudomonas, and SJA-88 as the common genera in all the four termites. The diversity of gut bacterial communities in the higher termite guts was significantly greater than that in the lower termites; while the gut microbiota in M. shangchengensis (wood-feeding higher termite) was more similar to those of the wood-feeding lower termites rather than that of O. formosanus (fungus-feeding higher termite), and phylum Spirochaetes and nitrogen-fixing bacteria were super-dominant in the wood-feeding termites, despite of their phylogenetic relations. This study reported for the first time the gut bacterial communities for the termites of M. shangchengensis and T. ampliceps and the comparative analyses showed that the gut microbial communities varied according to the phylogeny and the diet habits of termites.

    The vomeronasal organ of sheep was examined using lectin histochemistry in order to compare the types and amounts of the glycoconjugates among various components of the vomeronasal sensory and non-sensory epithelia. In the vomeronasal sensory epithelium, Dolichos biflorus agglutinin (DBA) stained particular cells, located at the same level as the vomeronasal receptor cells, while the distribution, shape and number of the stained cells did not correspond to those of the vomeronasal receptor cells. Datura stramonium lectin (DSL), Concanavalin A (Con A), Phaseolus vulgaris agglutinin-E (PHA-E) and Phaseolus vulgaris agglutinin-L (PHA-L) labeled the basal cells of both vomeronasal sensory and non-sensory epithelia. While, Wheat germ agglutinin (WGA), Succinylated-wheat germ agglutinin (s-WGA), Lycopersicon esculentum lectin (LEL), Solanum tuberosum lectin (STL) and Ricinus communis agglutinin-I (RCA-120) labeled the basal cells of the sensory epithelium, and Bandeiraea simplicifolia lectin-I (BSL-I) stained the basal cells of the non-sensory epithelium, respectively. Seventeen lectins labeled the free border of both vomeronasal sensory and non-sensory epithelia, while Sophora japonica agglutinin (SJA), Jacalin and Pisum sativum agglutinin (PSA) labeled neither free border of the sensory nor that of non-sensory epithelia. The expression pattern of glycoconjugate was similar, but not identical, in the free border between the sensory and non-sensory epithelia. These results indicate that there are dissimilar features in the type and amount of glycoconjugates between the vomeronasal sensory and non-sensory epithelia, and at the same time, among the various cell types either in the vomeronasal sensory or non-sensory epithelium.

    Iota Herculis is an ultrasharp-lined B3IV star that historically has been considered as an abundance standard for the early B stars. New abundances of the lighter and Fe group elements have been determined with the aid of high resolution spectral data from HST/STIS and the Dominion Astrophysical Observatory. The HST spectra were obtained with the STIS E140M and E230M gratings and cover the region 1160-2350 A with a 2-pixel spectral resolution that varies from 0.03-0.08 A. The DAO spectral atlas covers 3820-5350 A in the second order with a 2-pixel resolution 0.072 A. We compare theoretical spectra computed from the NLTE code TLUSTY/SYNSPEC (I. Hubeny & T. Lanz, ApJ, 439,875,1995) and the LTE code ATLAS9/SYNTHE (R. Kurucz, 1993, CD-ROMs 13 & 18) with the observations. The model parameters adopted for the star are Teff = 17,500 K, log g = 3.75, Vturb = 0 km/s, and vsin i = 5 km/s. Solar abundances appear to prevail for the lighter elements but the abundances of Fe group elements are 0.1-0.3 dex below the solar values given by Asplund, Grevesse, & Sauval (2005). In general the NLTE calculations fit the observations better, especially for lines formed high in the atmosphere such as the C I lines near 1260 A. The detailed analysis of the spectrum of this standard star not only allows one to determine the abundances in the atmosphere of a typical field B star but also presents the opportunity to assess the accuracy of atomic parameters for UV lines and find astrophysical f-values. The authors appreciate support from NASA and STScI grants NAG5-11802 and GO-09848. SJA was a guest observer at DAO.

    Abuse of 3,4-methylenedioxymethamphetamine (MDMA or Ecstasy) and methamphetamine (Meth or Speed) is a growing international problem with an estimated 250 million users of psychoactive drugs worldwide. It is important to demonstrate and understand the mechanism of neurotoxicity so potential prevention and treatment therapies can be designed. In this study rat primary cerebrocortical neuron cultures were challenged with MDMA and Meth (1 or 2 mM) for 24 and 48 h and compared to the excitotoxin N-methyl-D-aspartate (NMDA). The neurotoxicity of these drugs, as assessed by microscopy, lactate dehydrogenase release and immunoblot, was shown to be both dose- and time-dependent. Immunoblot analysis using biomarkers of cell death showed significant proteolysis of both alphaII-spectrin and tau proteins. Breakdown products of alphaII-spectrin (SBDPs) of 150, 145, and 120 kDa and tau breakdown products (TBDPs) of 45, 32, 26, and 14 kDa were observed. The use of the protease inhibitors calpain inhibitor SJA6017 and caspase inhibitors z-VAD-fmk and Z-D-DCB, attenuated drug-induced alphaII-spectrin and tau proteolysis. The calpain inhibitor reduced the calpain-induced breakdown products SBDP145 and TBDP14, but there was an offset increase in the caspase-mediated breakdown products SBDP120 and TBDP45. The caspase inhibitors, on the other hand, decreased SBDP120 and TBDP45. These data suggest that both MDMA and Meth trigger concerted proteolytic attacks of the structural proteins by both calpain and caspase family of proteases. The ability of the protease inhibitors to reduce the damage caused by these drugs suggests that the treatment arsenal could include similar drugs as possible tools to combat the drug-induced neurotoxicity in vivo.

    Recently, it was shown that conversion of cdk5 activator protein p35 to a C-terminal fragment p25 promotes a deregulation of cdk5 activity, which may contribute to neurodegeneration in Alzheimer's disease. In this study, we present evidence that calpain is a protease involved in the conversion of p35 to p25. To activate calpain, rat cerebellar granule neurons were treated with maitotoxin (MTX). A C-terminus-directed anti-p35 antibody detected that p35 conversion to p25 paralleled the formation of calpain-generated alpha-spectrin (alpha-fodrin) breakdown products (SBDP's) in a maitotoxin-dose-dependent manner. Two calpain inhibitors (MDl28170 and SJA6017) reduced p35 processing but were unchanged when exposed to the caspase inhibitor carbobenzoxy-Asp-CH(2)OC(=O)-2, 6-dichlorobenzene or the proteasome inhibitors (lactacystin and Z-Ile-Glu(OtBu)Ala-Leu-CHO). p35 protein was also degraded to p25 when rat brain lysate was subjected to in vitro digestion with purified mu- and m-calpains. Additionally, in a rat temporary middle cerebral artery occlusion model, p35 processing to p25 again paralleled SBDP formation in the ischemic core. Lastly, in malonate-injured rat brains, the ipsilateral side showed a striking correlation of SBDP formation with p35 to p25 conversion and tau phosphorylation (at Ser202 and Thr205) increase. These data suggest that calpain is a major neuronal protease capable of converting p35 to p25 and might play a pathological role of activating cdk5 and its phosphorylation of tau in Alzheimer's disease.

Traffic in and around the Svalbard settlements is increasing, and at the same time global climate models project substantial increases in temperature and precipitation in northern high latitudes for coming century. Therefore improved knowledge on the effect of climatic changes on slope processes in such high arctic landscapes is becoming increasingly important. Motivated by this, the CRYOSLOPE Svalbard research project since 2007 has carried out field observations on snow avalanche frequency and associated meteorological conditions. Snow avalanches are important geomorphic agents of erosion and deposition, and have long been a source of natural disasters in many mid-latitude mountain areas. Avalanches as a natural hazard has thereby been familiar to inhabitants of the Alps and Scandinavia for centuries, while it is a more recent experience in high arctic Svalbard. In addition, overall climate, topography and especially high winter wind speeds makes it difficult to apply snow avalanche models (numerical or empirical) developed for use at lower latitudes, e.g. in central Europe. In the presentation we examplify results from the ongoing (since winter 2006-07) monitoring of snow avalanches in Svalbard along a 70 km long observational route in the mountains. In addition, we present observations on the geomorphological impact of avalanches, with special reference to the formation of rock glaciers.

    Background: Mycoplasma genitalium (M. genitalium) has been shown to be involved in chronic non-gonococcal urethritis (NGU). However, the prevalence and determinants of this emerging sexually transmissible infection among prostatitis patients remain obscure. Methods: Two hundred and thirty-five patients diagnosed with prostatitis and 152 health controls from sexually transmitted diseases (STD) clinics in Shanghai, China, were selected. M. genitalium was detected in the initial voided urine (VB1), midstream of urine (VB2), expressed prostatic secretion (EPS) and the opening urine after massage (VB3) by quantitative polymerase chain reaction (Q-PCR) targeting the Mycoplasma genitalium adhesion protein (MgPa). An infection of the prostate was considered positive if a uropathogen was found only in the EPS sample or VB3, or if it was at least four-fold greater in EPS or VB3 than in VB1 or VB2. The prostatitis patients with M. genitalium infection were treated with azithromycin. Results: The prevalence of M. genitalium infection was significantly higher among the prostatitis group than the control group (10 vs 3%, P = 0.005). Among the prostatitis group, M. genitalium infection was significantly associated with those patients who received treatment for genitourinary infection previously than those patients who did not (17 vs 6%; adjusted OR, 4.011; 95% CI, 1.562-10.300). The symptoms were totally or partially improved in 83% per cent (19/23) of prostatitis patients with M. genitalium, positive in EPS and M. genitalium turned negative after azithromycin treatment. Conclusions: M. genitalium was prevalent in the patients with prostatitis, particularly in those who received ineffective antibiotic treatment for the bacterium, and was identified as having a significant association of prostatitis.

    The effect of tsetse/trypanosomiasis control on cattle herd composition and growth and mortality of calves in tsetse controlled (by Southern Tsetse Eradication Project (STEP)) and uncontrolled blocks in southern Ethiopia was assessed. Structured questionnaire was used to interview 182 households to estimate cattle herd composition and calf mortality. Calves were bled to examine the presence of trypanosomes by the buffy coat technique. Forty NGU traps were deployed and fly catches determined. A case-control study was performed on 40 calves for 6 months to estimate calve growth parameters. Accordingly, the mean cattle herd size was lower in tsetse-controlled block than in the uncontrolled block, whereas the relative number of calves in a herd tend to be higher in the tsetse-controlled block (P = 0.06). While there was no report of cattle mortality in tsetse-controlled block, 16.48 % of the respondents have lost calves in tsetse-uncontrolled block in 1 year time. The prevalence of trypanosome positive calves was 2.95 % for uncontrolled block but no positive case in tsetse-controlled block. The apparent densities of flies/trap/day in tsetse-uncontrolled block were 30-fold higher than in tsetse-controlled block (P < 0.01). The case-control study revealed that the mean body weight gain of calves in tsetse-controlled block (40.23 ± 0.7 kg) was significantly higher than that of the uncontrolled block (34.74 ± 0.68 kg). The above findings strongly suggest that the intervention by the STEP project has significantly reduced tsetse population and trypanosomiasis consequently contributing to improved calf growth and survival.

    strong motion networks monitor seismic activity and hazard in the North Atlantic. Vigorous volcanic activity along the plate boundary in Iceland and associated hazards are monitored by the Icelandic, seismic, geodetic, meteorological and hydrological networks. Recent eruptions, like the 2010 Eyjafjallajökull eruptions have demonstrated the far-reaching hazard to aviation caused by volcanic eruptions in Iceland. The high-sensitivity seismic and geodetic networks of Sweden monitor isostatic rebound of Fennoscandia. In this context, the varied Nordic monitoring networks provide a significant contribution to the main objectives of EPOS. There are already existing links with the other ESFRI initiatives where strong Nordic participation is established, such as SIOS and EMSO. As such EPOS provides the necessary platform to collaborate and develop an important Nordic dimension in the European Research Area. There is a long tradition of collaboration at the governmental level between the Nordic countries, Norway, Sweden, Denmark, Finland and Iceland. Within the fields of research and education, the Nordic Ministries have a dedicated program, where research networks are being promoted. Recently a Nordic collaborative network in seismology, "NordQuake" (coordinated by Denmark) was established within this program. This collaboration which is now formalized and supported by the Nordic Ministries is based on a cooperation which was initiated more than 40 years ago, where annual Nordic Seminars in seismology (previously on detection seismology) was the central element. EPOS Nordic collaboration, building upon a long lasting history, has a significant potential for synergy effects in the region and therefore represents an important dimension within EPOS.

    Iota Herculis is an ultrasharp-lined B3 IV star that historically has been considered as an abundance standard for the early B stars. This star was one of the targets in the HST Treasury Program Advanced Spectral Library II: Hot Stars (ASTRAL II) that produced uninterrupted spectra of high to medium resolution in the region 1150-3100 Å. The abundances for the Fe group elements (Ti, V, Cr, Mn, Fe, Co, & Ni) in ι Her were determined mostly from STIS E140H and E230H (resolving power of 114,000) observations. Measurable lines from the Fe group, except for a very few multiplets of Fe II, III are not found in optical spectra. Whereas the light elements are delivered to the ISM by core-collapse supernovae (CCSNe), the Fe group elements are believed to come mostly from low/intermediate mass binaries containing white dwarfs that undergo SNe Ia explosions. A single SNe Ia can deliver 0.5 solar masses of pure Fe (and maybe Mn) to the ISM compared with about 0.07 solar masses from a CCSNe. The HST/STIS data were supplemented with optical spectra obtained at the Dominion Astrophysical Observatory (resolving power about 60,000). The abundance analysis was carried through with the NLTE code TLUSTY/SYNSPEC (Hubeny & Lanz, ApJ, 439,875,1995). The model parameters adopted for the ι Her are Teff = 17750 ± 250 K, log g = 3.75 ± 0.05 dex, Vturb = 0 km s-1, and v sin i = 5 km s-1. Solar abundances appear to prevail for the lighter elements but the abundances of Fe group elements are 0.3 - 0.7 dex below solar values determined by Grevesse et al. (2010, Ap&SpSci, 328, 179). It appears that ι Her was formed in a region our Galaxy mostly enriched by CCSNe.The authors appreciate support from STScI grants HST-GO-09848 and HST-GO-13346. SJA was a guest observer at DAO.

    Catastrophic failure of large rock slopes led several times per century in Norway to rock avalanches or large rock falls, which impacted into settlements directly but also caused either a displacement wave when impacting a water body or damming of narrow valleys that impacred settlements in distance with often deadly consequences. Such events will also occur in future. In order to make mitigation of the negative consequences of such events possible, the Geological Survey of Norway (NGU) following its obligation towards society and the Norwegian Water and Energy Directorate (NVE) carries out systematic geologic mapping of potentially unstable rock slopes that might fail catastrophically. Within the last years systematic mapping in only three of the 17 counties of Norway has revealed more than 300 sites of potential future rock slope failures. This number necessitates prioritization of follow-up activities, such as periodic and permanent monitoring and early-warning. This quantitative hazard and risk classification system was build to compare sites so that political and financial decisions can be taken. The classification system is scenario-based as intensity and rate of displacement, as well as the geological structures activated by the sliding rock mass vary significantly on slopes. In addition, for each scenario the secondary effects, such as generation of displacement waves or landslide damming of valleys with the potential of later outburst floods, have to be evaluated. The hazard classification is based on two sets of criteria: 1) Structural site investigations including analysis of the development of the back-scarp, lateral limits and basal sliding surface. This includes a kinematic analysis that tests if rock sliding or toppling is kinematically feasible with respect to the slope orientation, the persistence of main structures and the morphologic expression of the sliding surface. 2) The analysis of the activity of the slope is primarily based on the slide

    African animal trypanosomosis (AAT) is a parasitic disease that causes serious economic losses in livestock from anemia, loss of condition, emaciation and death in untreated cases. It is one of the major constraints to improved livestock production and productivity in Ethiopia. Entomological and parasitological surveys were conducted in the Omo-Ghibe tsetse belt of south Ethiopia to estimate the prevalence of bovine trypanosomosis and the apparent tsetse density (AD), and identify the potential risk factors. For the parasitological study, blood samples were collected from 1508 cattle sampled from 11 districts and assayed using the buffy coat technique and Giemsa-stained thin smears. For the entomological survey, a total of 216 biconical and NGU traps were deployed in all districts. The overall animal-level prevalence of trypanosomosis was 7.8% (95% CI: 6.5, 9.3). The trypanosome species identified were Trypanosoma congolense (75.4%), T. vivax (20.3%), T. brucei brucei (1.7%) and mixed T. congolense/T. vivax (2.6%). Regarding the entomological survey result, a total of 2243 tsetse flies were captured which identified to be Glossina pallidipes (85.1%) and G. f. fuscipes (14.9%). Besides, other biting flies of the genus Stomoxys (n=146) and Tabanus (n=17) were also trapped. The AD noted in the present study was 3.5 flies/trap/day. Both the prevalence of trypanosomosis and AD of tsetse flies were significantly (p<0.05) influenced by altitude. The prevalence of trypanosomosis was also significantly (p<0.05) associated with poor body condition score, black coat color and lower mean packed cell volume while no significant prevalence difference was noted along with age and sex category. In conclusion, the present study suggested that trypanosomosis is an important disease of cattle in the Omo-Ghibe tsetse belt in dry season. The disease is mainly caused by the most pathogenic T. congolense and transmission is predominantly by tsetse flies, particularly G. pallidipes. The

    As one of 13 new `Centres of Excellence' awarded by the Norwegian Research Council with a 10-year funding schedule, the International Centre for Geohazards (ICG) was established at the Norwegian Geotechnical Institute (NGI), in January 2003. The Centre is formed through a co-operation between several institutions, which in addition to NGI are the Gelogical Survey of Norway (NGU), Norwegian Seismic Array (NORSAR), University of Oslo (UiO) and the Norwegian University for Science and Technology (NTNU). The Centre is located in the NGI building in Oslo, Norway. Funding is for 10 years, and the centre is staffed by researchers from the partner institutions, visiting scientists, post-doctoral fellows and Ph.D. students. With the ultimate goal of geohazard mitigation and preventing the loss of lives and damage to infrastructure and environment, key research topics of the Centre are: Unsaturated soils and mechanisms for precipitation-induced slides in steep slopes; Risk and vulnerability analysis for geohazards; Earthquake hazard, vulnerability and risk evaluation; Rock slope failures - models and risks; Landslides in soft clay slopes (quick clay), fjord margins and coastal zones; GIS applications to geohazards; SAR applications to geohazards; Slide dynamics and mechanics of disintegration; Tsunami modelling and prediction; and Offshore Geohazards. As prospecting for hydrocarbons move into increasingly deeper waters of the world's continental margins, research on offshore geohazard forms an important activity of the new centre. Main offshore geohazards include slope instability, effects of shallow gas and gas hydrates on the behaviour of seafloor sediments, mud volcanism and diapirism. Of these, slope instability is considered to be the major hazard, because of the potentially serious third party impact. The current offshore geohazards project within ICG consists of three main themes: Assessment of offshore geohazards (site surveys); Geophysical methods for offshore

  8. Robust control methods for nonlinear systems with uncertain dynamics and unknown control direction

    consideration is required in control design for systems that also include unknown bounded disturbances. To cope with these challenges, a robust continuous controller is developed using an ISMC technique, which achieves asymptotic trajectory tracking for systems with unknown bounded disturbances, while simultaneously compensating for parametric uncertainty in the input gain matrix. The ISMC design is rigorously proven to achieve asymptotic trajectory tracking for a quadrotor system and a synthetic jet actuator (SJA)-based aircraft system. In the ISMC designs, it is assumed that the signs in the uncertain input-multiplicative gain matrix (i.e., the actuator control directions) are known. A much more challenging scenario is encountered in designing controllers for classes of systems, where the uncertainty in the input gain matrix is extreme enough to result in an a priori-unknown control direction. Such a scenario can result when dealing with highly inaccurate dynamic models, unmodeled parameter variations, actuator anomalies, unknown external or internal disturbances, and/or other adversarial operating conditions. To address this challenge, a SMCbased self-recongurable control algorithm is presented, which automatically adjusts for unknown control direction via periodic switching between sliding manifolds that ultimately forces the state to a converging manifold. Rigorous mathematical analyses are presented to prove the theoretical results, and simulation results are provided to demonstrate the effectiveness of the three proposed control algorithms.

    Soil A-horizon and C-horizon samples were collected along a 4000 km long transect cutting the USA from the west to the east coast. For purposes of site selection, the transect was divided into approximately 40-km segments. For each segment, a 1-km2 target area was selected at random. Soil A- and C-horizon samples were collected at a site within each target area that was most representative of the surrounding landscape. The samples were air-dried at ambient temperature, disaggregated, and sieved through a 2-mm stainless steel screen. The <2-mm material was crushed to <150 µm in a ceramic mill prior to chemical analysis. Lead was analyzed in all the A- and C-horizon samples by inductively coupled plasma-mass spectrometry following a 4-acid digestion. The complete dataset can be found in Smith et al., 2005. Pb-isotope ratio measurements were carried out on 159 soil A-horizon and 137 soil C-horizon samples on an inductively coupled sector field plasma mass spectrometer (SF-ICP-MS; ELEMENT 1, Finnigan MAT) in the laboratory of the Geological Survey of Norway (NGU), following a 7 N HNO3 digestion. Lead concentrations along the transect show (1) generally higher values in the soil A-horizon than the C-horizon (median 21 vs. 16.5 mg/kg), (2) an increase in the median value of the soil A-horizon for the central to eastern U.S. (Missouri to Maryland) when compared to the western U.S. (California to Kansas) (median 26 vs. 20 mg/kg) and (3) a higher A/C ratio for the central to eastern US (1.35 vs. 1.14). Lead isotopes show a distinct trend across the U.S., with the highest 206Pb/207Pb ratios occurring in the centre (Missouri, median A-horizon: 1.245; C-horizon: 1.251) and the lowest at both coasts (e.g. California, median A-horizon: 1.195; C-horizon:1.216). The soil C-horizon samples show generally higher 206Pb/207Pb ratios than the A-horizon (median C-horizon: 1.224; A-horizon: 1.219). The 206Pb/207Pb isotope ratios in the soil A horizon show a correlation with the total

    Silurian and Devonian deposits in Viet Nam are present in several zones and regions, including Quang Ninh, East Bac Bo, and West Bac Bo Zones of the Bac Bo Region, the Dien Bien-Nghe An and Binh Tri Thien Zones of the Viet-Lao Region, and the South Trung Bo, and Western Nam Bo Zones of the South Viet Nam Region (Fig. 1). The main lithological features and faunal composition of the Silurian and Devonian Units in all these zones are briefly described. The Silurian consists of deep-water deposits of the upper parts of the Co To and Tan Mai Formations in the Quang Ninh Zone, the upper parts of the Phu Ngu Formation in the East Bac Bo Zone and the upper parts of the Long Dai and Song Ca Formations in the Viet-Lao Region. Shallow water facies Silurian units containing benthic faunas are more widely distributed, including the upper part of the Sinh Vinh and Bo Hieng Formations in the West Bac Bo Zone, the Kien An Formation in the Quang Ninh Zone, and, in the Viet-Lao Region, the Dai Giang Formation and the upper part of the Tay Trang Formation. No Lower and Middle Devonian deposits indicate deep water facies, but they are characterized by different shallow water facies. Continental to near shore, deltaic facies characterize the Lower Devonian Song Cau Group in the East Bac Bo Zone, the Van Canh Formation in the Quang Ninh Zone, and the A Choc Formation in the Binh Tri Thien Zone. Similar facies also occur in the Givetian Do Son Formation of the Quang Ninh Zone, and the Tan Lap Formation in the East Bac Bo Zone, and consist of coarse terrigenous deposits—cross-bedded conglomerates, sandstone, etc. Most Devonian units are characterized by shallow marine shelf facies. Carbonate and terrigenous-carbonate facies dominate, and terrigenous facies occur in the Lower and Middle Devonian sections in some areas only. The deep-water-like facies is characteriztic for some Upper Devonian formations in the Bac Bo (Bang Ca and Toc Tat Formations) and Viet-Lao Regions (Thien Nhan and

The innovative approach of this international research project is the integrated quantitative study of longer-term (Holocene), subrecent and contemporary source-to-sink fluxes and geomorphic process rates in selected representative valley-fjord systems using a novel combination of advanced methods and techniques. With respect to the main aims and objectives of ESF SedyMONT, the following main aims of the Erdalen and Bødalen site project can be stressed: - Analyse how the inheritance of the landscape due to the influence of the Last Glacial Maximum (LGM) has affected process rates over time (paraglacial system), - Document changes in process rates over different timescales by combining quantitative knowledge on Holocene process rates with newly generated data on subrecent and contemporary process rates. High-resolution monitoring of denudative surface processes in Erdalen and Bødalen, in combination with repeated analyses of surface water chemistry, atmospheric solute inputs and granulometric as well as shape analyses of suspended sediments provide high-resolution data to analyse and quantify present-day sedimentary and solute fluxes as well as sediment sources, denudation rates, and meteorological and topographical / landscape morphometric controls of denudative processes. In addition to standard methods for monitoring bedload transport, innovative techniques like horizontally installed impact sensors and biofilm analysis are applied in combination with advanced flume experiments (for calibration of field data) to analyse channel stability / mobility and to

    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.

    Steep glacially carved valleys and fjords in Norway are prone to many landslide types, including large rockslides, rockfalls, and debris flows. Large rockslides and their secondary effects (rockslide-triggered displacement waves, inundation behind landslide dams and outburst floods from failure of landslide dams) pose a significant hazard to the population living in the valleys and along the fjords shoreline. The Geological Survey of Norway performs systematic mapping of unstable rock slopes in Norway and has detected more than 230 unstable slopes with significant postglacial deformation. This large number necessitates prioritisation of follow-up activities, such as more detailed investigations, periodic displacement measurements, continuous monitoring and early-warning systems. Prioritisation is achieved through a hazard and risk classification system, which has been developed by a panel of international and Norwegian experts (www.ngu.no/en-gb/hm/Publications/Reports/2012/2012-029). The risk classification system combines a qualitative hazard assessment with a consequences assessment focusing on potential life losses. The hazard assessment is based on a series of nine geomorphological, engineering geological and structural criteria, as well as displacement rates, past events and other signs of activity. We present a method for consequence assessment comprising four main steps: 1. computation of the volume of the unstable rock slope; 2. run-out assessment based on the volume-dependent angle of reach (Fahrböschung) or detailed numerical run-out modelling; 3. assessment of possible displacement wave propagation and run-up based on empirical relations or modelling in 2D or 3D; and 4. estimation of the number of persons exposed to rock avalanches or displacement waves. Volume computation of an unstable rock slope is based on the sloping local base level technique, which uses a digital elevation model to create a second-order curved surface between the mapped extent of
