ACOUSTIC EMISSION TESTING OF SEAM-WELDED HIGH ENERGY PIPING SYSTEMS IN FOSSIL POWER PLANTS (2007)

The structural integrity of seam-welded fossil high-energy piping has remained a major safety and operations-maintenance issue for US utility companies. Several failures of seamwelded superheat and hot reheat piping segments have occurred since 1992, two of them catastrophic. Advanced methods of inspecting piping welds with ultrasonic testing (UT), such as time-of-flight diffraction and focused/phased arrays, are pushing back the envelope of detection to earlier stages of creep damage, but these are still very expensive, and involve considerable logistical planning and downtime to perform. The Electric Power Research Institute (EPRI) has sponsored development activities since 1986 to mature the utilization of a real-time online evaluation method for seam-welded piping: Acoustic emission (AE) testing guidelines were published by EPRI in 1995, and over 100 full-scale tests have been performed to develop a database and correlate results with other established evaluation methods. An effort was begun in 2002 to standardize the testing method within ASTM (AE Subcommittee of E07.04) utilizing the developed database. Tests to date have shown high sensitivity to early stage creep damage, which is evidenced by development of cavities around inclusions in the grain boundaries. Successful double-blind testing with advanced ultrasonic inspection methods has proven both the reliability and sensitivity of the AE technique. The economics of the method are highly favorable. Only small areas of insulation need to be removed every 4.6-6 m to weld waveguides to the piping surface. These form a linear location array along the length of piping, providing global coverage of the piping system. Testing is performed online with normal peak loading and load cycling. No outage schedule is required to perform the AE examination. Results will be presented showing that the AE method has become a reliable and economical field evaluation tool for seam-welded high energy piping.

Teacher decisions about planning and assessment in primary mathematics (2012)

We are interested in exploring the processes teachers use when planning. We sought responses from teachers on aspects of their planning from a survey of various aspects of their decisions. We found that, while there is diversity in processes teachers use for planning, a consistent theme was that teachers make deliberative decisions at all stages in the planning process. Likewise teachers make active use of assessment information, especially to address the needs of their students. There are important implications from our findings for those who support teachers in the transition to the Australian Curriculum: Mathematics.
Levetiracetam Effect in Demyelinating Ocular Flutter with Myoclonus (2006)

A 29-year-old male developed ocular flutter and subtle extremity myoclonus related to demyelination. Ocular flutter and myoclonus were symptomatically amenable to treatment with levetiracetam. Discontinuation of levetiracetam was associated with recurrent flutter and myoclonus over a two-year period of follow-up. Levetiracetam may be an effective agent for the symptomatic control of ocular flutter.
Urocortin 2 and urocortin 3 in endometriosis: evidence for a possible role in inflammatory response (2011)

Urocortin 2 (Ucn 2) and urocortin 3 (Ucn 3) are neuropeptides expressed by human endometrium. This study evaluated (i) the expression of Ucn 2 and Ucn 3 mRNA in endometriotic lesions and in endometrium of women with endometriosis; (ii) the effect of Ucn 2 and Ucn 3 on cytokines secretion from cultured endometrial stromal cells. Endometriotic tissue was collected from endometrioma (n=39); endometrial specimens were obtained from women with (n=39) and without (n=41) endometriosis throughout menstrual cycle. Tissue specimens were analysed for Ucn 2 and Ucn 3 mRNA expression and peptide localization; the effects of Ucn 2 or Ucn 3 on tumour necrosis factor (TNF-α) and interleukin (IL-4) secretion from cultured endometrial stromal cells was studied. Ucn 2 and Ucn 3 mRNA expression and localization were assessed by RT-PCR and by immuohistochemistry, respectively; cytokines secretion were measured by ELISA. Results showed that endometriotic tissue expressed both Ucn 2 and Ucn 3, with Ucn 3 expression higher in ectopic than in eutopic endometrium. Endometrial Ucn 2 mRNA expression in controls showed peak values at early proliferative phase, while in endometriotic patients low expression and no significant changes throughout menstrual cycle were observed. Endometrial Ucn 3 mRNA expression was highest in late secretory phase in controls, while in endometriotic patients low levels and no menstrual-cycle-related changes were found. When added to cultured endometrial cell cultures, Ucn 2 significantly increased TNF-α (P<0.01) and IL-4 (P<0.001), while Ucn 3 induced an increase of IL-4 secretion (P<0.01). In conclusion, endometriotic tissue expressed and localized Ucn 2 and Ucn 3; patients with endometriosis showed Ucn 2 and Ucn 3 mRNA expression in eutopic endometrium lower than in control group, with no endometrial cycle-related changes. Ucn 2 and Ucn 3-modulated TNF-α and IL-4 secretion from culture endometrial cells. These data suggest a possible involvement of Ucn 2 and Ucn 3 in the mechanisms of endometriosis.
Microcontrollers as material (2013)

Embedded programming is typically made accessible through modular electronics toolkits. In this paper, we explore an alternative approach, combining microcontrollers with craft materials and processes as a means of bringing new groups of people and skills to technology production. We have developed simple and robust techniques for drawing circuits with conductive ink on paper, enabling off-the-shelf electronic components to be embedded directly into interactive artifacts. We have also developed an set of hardware and software tools -- an instance of what we call an "untoolkit" -- to provide an accessible toolchain for the programming of microcontrollers. We evaluated our techniques in a number of workshops, one of which is detailed in the paper. Four broader themes emerge: accessibility and appeal, the integration of craft and technology, microcontrollers vs. electronic toolkits, and the relationship between programming and physical artifacts. We also expand more generally on the idea of an untoolkit, offering a definition and some design principles, as well as suggest potential areas of future research.

Compensated Neutron-Gamma Density for Formation Evaluation, Continuing Field Tests Demonstrate Improvements and New Features (2011)

Abstract Compensated neutron-gamma density (NGD) is a nuclear density measurement that can be made without a chemical gamma ray source. The measurement uses fast neutrons from an electronic pulsed neutron generator (PNG). These fast neutrons penetrate the formation and collide with and excite atomic nuclei. The nuclei rapidly return to their original energy state and emit gamma rays, some of which are scattered back to the detectors. The count rate of detected gamma rays, compensated for fast neutron transport effects, depends on formation electron density. This new measurement is desirable where operating with a chemical source is prohibited or the risk of loosing the drill string in hole is high. The NGD measurement was first deployed on logging-while-drilling (LWD) equipment to minimize the impact of stuck-pipe events and to provide a density measurement with greater depth of investigation into the formation. The first implementation of the measurement used a ruggedized PNG as a source and a single detector, but the single detector configuration rendered the measurement sensitive to standoff. A caliper input was required to correct this effect, but introduced additional uncertainty. The measurement evolved to a standoff-compensated density using two detectors at different spacings from the PNG. The two detector responses are processed by means of a spine-and-ribs algorithm to correct for borehole effects, much like traditional cesium-based density measurements. This compensated NGD measurement provides standoff- compensated formation bulk density for formation evaluation, without using a chemical source. The compensated NGD algorithm has been tested on various field datasets. The results are compared against an earlier uncompensated NGD algorithm and traditional gamma-gamma density (GGD) measurements. This paper provides an overview of the current compensated algorithm's advantages and highlights limitations that are currently being addressed through ongoing development.

Resistance to Tobacco Etch Virus in <i>Capsicum annuum:</i> Inhibition of Virus RNA Accumulation (1997)

Resistance to tobacco etch potyvirus (TEV) in Capsicum annuum cv. Dempsey gene et a . When Dempsey pepper plants were inoculated with either of two TEV isolates, virus did not accumulate in inoculated or noninoculated leaves. In contrast, each TEV isolate replicated to high levels in C. annuum cv. Jupiter, a susceptible parent of Dempsey pepper. To determine the basis of the resistance, Dempsey and Jupiter pepper plants were inoculated with a TEV isolate (TEV-HAT) engineered to express the β-glucuronidase gene (TEV-GUS). TEV-GUS moved cell-to-cell and systemically in infected Jupiter pepper plants. In contrast, there was no evidence of any single-cell infection foci induced by TEV-GUS in Dempsey pepper plants. Northern blot analysis of protoplasts inoculated with TEV-HAT RNA indicated that virus RNA did not accumulate in Dempsey pepper protoplasts, whereas TEV-HAT did replicate and accumulate in protoplasts from Jupiter pepper plants. Thus, the resistance to TEV conferred by the et a gene is due to interference with virus RNA accumulation.
EFFECTS OF BLUE, RED, AND BLUE/RED LIGHTS OF TWO DIFFERENT PPF LEVELS ON GROWTH AND MORPHOGENESIS OF LETTUCE PLANTS (1996)

To clarify the possibility of plant production under red and blue monochrome light using light emitting diodes (LEDs), the effects of light quality and photosynthetic photon flux (PPF) on the growth and morphogenesis of lettuce plants were examined. Lettuce plants were hydroponically grown for 20 days, under 3 different light qualities (Red, Blue and Red/Blue) and 2 PPF levels (about 85 and 170 micromoles/m2/s) for a l6hr day and an 8hr night cycle, at a temperature range of 20 to 22 degrees C. Irrespective of the two different PPF levels, the plants grown under the red LEDs developed more leaves than the plants under the blue LEDs, but less leaves than the plants under blue/red light. The curvature rate of the leaf margin in the plants grown under the blue LEDs was less than that of the plants under red LEDs on both PPF levels. The inclination angle of the seventh leaf in the plants grown under the blue LEDs and the blue/red fluorescence lamps was greater than that of the plants under red LEDs on the high PPF level. The whole plant dry weight was greater in the plants grown under the high PPF level than the plants under a low PPF level.
ICOMA: an open infrastructure for agent-based intelligent electronic commerce on the Internet (2002)

With the increasing importance of EC (Electronic Commerce) across the Internet, the need for agents to support both customers and suppliers is growing rapidly. But the lack of standard on product ontology, message and negotiation protocol between agents and brokering makes full automation of EC infeasible. In this paper, we describe an open infrastructure for agent-based EC and design a virtual market server. As an open infrastructure, we propose a complete architecture and message protocol for inter-agent negotiation. We designed and partially implemented a virtual marker server, named ICOMA (Intelligent electronic COmmerce system based on Multi-Agent) based on the advanced agent technologies. The goal of ICOMA is to construct the decentralized, dynamic, and diverse EC environment.

How to Create a Performance Model of a Gas Turbine From a Limited Amount of Information (2005)

Gas turbine manufacturers develop complex performance simulation models for their products; these proprietary models are based on design information and the many measurements taken during engine development. For subcontractors in collaborative projects, for gas turbine users and outsiders there is often only a limited amount of data accessible for creating a performance model of the engine. User-friendly, accurate and fast PC-based engine simulation tools are available for anybody from several sources. With these tools it is possible to create from a limited amount of data full thermodynamic models. In this paper a methodology is presented which minimizes the effort needed for creating such models. It consists of four steps: Firstly a suitable cycle reference point is chosen and the model is tailored to the data of this point. Secondly compressor and turbine maps are added and scaled such that they fit exactly to the cycle reference point. In this step a second operating point is considered and the location of the cycle reference point in the component maps is adapted such that the simulation fits optimally to the given data of the second point. In a third step, the rest of the data are compared graphically with the simulation. Here many modelers fall in a trap: They plot the data versus spool speed as x-axis because speed is accurately measurable and regarded as reliable information. However, spool speed is — from the view of thermodynamics — a parameter of secondary importance. If the correlation of spool speed with corrected flow in the compressor map is incorrect — which is very probable at the beginning of the modeling process — then all graphics will show discrepancies. This makes the adaptation of the model to the data an extended iterative process. If one uses for the model checks a primary thermodynamic parameter — like corrected mass flow, overall pressure ratio or thrust respectively shaft power — as basis then the task is very much simplified. In the fourth and final step the speed values in the estimated compressor maps are adjusted. This has little effect on the matching accuracy of the previous steps, so the model is finished quickly. The procedure is demonstrated by creating a model for a two-spool turbojet which was tested over quite a range of operating conditions in an altitude test facility. Without much iteration a model is quickly created which matches all the measured data within the quoted uncertainty of the measurements.
Treatment of diffuse systemic sclerosis with hyperimmune caprine serum (AIMSPRO): a phase II double-blind placebo-controlled trial (2013)

These results confirm tolerability and safety of this novel biological agent in established diffuse SSc. The value of a placebo treated control group in small clinical trials evaluating skin disease in SSc is confirmed. Potential improvement in mRSS and changes in PIIINP in cases receiving active therapy suggest that this intervention may be of clinical benefit and warrants further evaluation.
Determination of tacrolimus in fermentation broth by reversed-phase liquid chromatography (2009)

To establish RP-HPLC method for the quantitative determination of tacrolimus in the fermentation broth,the determination was carried out on a Kromasil C8 column(250 mm×4.6 mm,5 μm).The mobile phase was isopropanol-water of 35∶65 with the flow rate of 1.0 mL/min,wave leagth was 220 nm and the column temperature was 50 ℃.The chromatographic conditions of the column,the mobile phase,the column temperature,and the wavelength were optimized.The results showed that the external standard calibration curve method to quantify tacrolimus by RP-HPLC was validated from 10 to 100 mg/L with satisfied linear relationship.The recovery rate of tacrolimus was 99.8% with the relative standard deviation of 0.58%.
Null-steering GPS dual-polarised antenna arrays (2003)

In this paper, the use of polarisation diversity in GPS adaptive antenna arrays is considered. The best way of applying the simple “null-steering” or “power inversion” criterion previously applied to non-polarimetric arrays is investigated. Two recently proposed approaches for applying null-steering techniques to polarimetric antenna arrays are reviewed and a new approach is introduced. Simulation results from an ideal polarimetric antenna array are used to compare the performance of the different techniques. Overall, the new approach maintains the best GPS satellite visibility in all interference scenarios studied in this paper.

Calcium and Vitamin D (2007)

Calcium is required for normal growth and development as well as maintenance of the skeleton. Vitamin D is also essential for intestinal calcium absorption and plays a central role in maintaining calcium homeostasis and skeletal integrity. In addition, both micronutrients have important roles in non-skeletal-related physiological processes. Of concern, significant proportions of some population groups fail to achieve the recommended calcium intakes in a number of western countries. Furthermore, while cutaneous biosynthesis upon exposure of skin to ultraviolet B light is the major source of vitamin D for most people, this does not occur during winter time. Thus, there is an increased reliance on dietary sources during winter months to help maintain adequate vitamin D status. Since vitamin D is found naturally only in a limited number of foods, the usual dietary vitamin D intake by many European populations is not sufficient to maintain adequate vitamin D status. This paper will briefly review these important issues together with consideration of the potential role for supplementation with calcium and vitamin D in terms of improving their intakes in the population. It will also focus on the issues of efficacy as well as safety considerations of supplements.
Analysis of stevioside in Stevia rebaudiana (2012)

Analysis of stevioside from Stevia rebaudiana was carried out using systematic procedures of various chromatographic techniques including column chromatography yielding the crude stevioside in 12.5%. This procedure was followed by thin layer chromatography and examination of the spots under UV light at 254 and 366 nm, and spraying reagent followed by mixing of fractions on the basis of Rf values. Semi purified fraction obtained from crude stevioside by column chromatography and further evaluation by thin layer chromatography appeared as a mixture showing the presence of four major components (Rf values 0.27, 0.34, 0.42 and 0.60). These finding were similar to reported values for the constituents namely rebaudiosides A, stevioside, rebaudiosides B and steviolbioside, and stevia glycoside reported to occur in Stevia rebaudiana.

Wetland reservation on Victoria's northern plains and riverine forests (2005)

\n\t\t\t\t\tThe depletion and reservation levels of wetlands varied significantly both across the Murray Fans and Victorian Riverina bioregions and in the study area of the Victorian Environmental Assessments Council's River Red Gum Forests Investigation. The proportion of Freshwater Meadows in protected areas was substantially lower than for other wetland types. Furthermore, of the wetlands that are reserved, many were only partially within a protected area. A variety of reserve categories are used to protect wetlands across the three regions, ranging from reserves with high legal protection and a strong focus on biodiversity conservation to reserves with a lower level of protection and emphasis on biodiversity<br />conservation. The findings highlight that many wetlands are incompletely reserved in Victoria's northern plains and riverine forests. The current review of public land use in the River Red Gum Forests, which includes Barmah Forest, should recognise these issues to ensure the effective reservation of wetland ecosystems.<br />\n\t\t\t\t
