NEW APPROACHES OF THE FORECAST OF THE AGEING OF PLASMA JET NOZZLE IN INDUSTRIAL SETTINGS OF THERMAL SPRAYING

The optimization of the extension of the timelife of the torches without hazard of drop of the product is an unceasing industrial difficulty. It needs a reliable criterion to characterize the wear, and thus indicate when the nozzle used should be switched by a new nozzle. These criteria are still quite subjective and hold the operator's experience. In 2003, David RIGOT, in collaboration with the Volvo Aero Corporation, has defined a number of criteria in his thesis dissertation [1]. This study led to the realization of an electronic module alert detecting the hazardous time of process. The focus method was based on research and tracking characteristic frequencies in arc voltage fluctuations and in acoustic noise that is the image. It seems that a rough statistical study of signals is able to help define and visualize simple criteria ruthless variation is usable in objective phenomena wear alert. This is ad hoc measures for smooth power spectrum [2] [3] and its variability. Filtered signal is used to distinguish typically one or two epochs of slow wear followed by an epoch of fast wear. This difference is clear after a suitable choice of used frequency bands. Graphical representations are very expressive; they are supplemented by statistical tests. Signals & method: results, by David RIGOT on campaign made shots in September 2003 at the aircraft manufacturer Volvo Aero. Files led to collect a series of measures standardized on the time life of the nozzles. For one, whose use was particularly long, a few shots "vacuum" were prosecuted beyond of the usual threshold used in order to study the ageing. Sound torch and tension thus collected at various times of operation nozzles, with several frequencies of sampling, feed and no feed of powder. They allow first approach directly extract global statistical parameters which it represents dissimilarity based on time: moments, skewness, kurtosis, entropy [4]. To each power spectra measurement, time is calculated from each signal multiple sampling. Each of the frequencies spectra is smooth inside of a convolution window by a kernel assessor [5]. A simultaneous representation of the power of signals and their erraticism are used to visually choose the most discriminating frequency bands. Two groups of settings are then assessed: mean and variance of spectrum in the band selected; global parameters newly evaluated from filtered in the chosen band signals. Results: most selective statistics evolve in a similar manner and allows periods wear, …
Distribution and Risk Assessment of Potential Invasiveness of Australoheros facetus (Jenyns, 1842) in Portugal

Invasive species are recognized as a major cause of biodiversity decline. Legal regulations relating to the prevention, control, or eradication of invasive species should always be up-to-date, as the failure to recognize the problem, lack of adequate scientific information, or long legal intervals required to prepare the legislation may result in irreversible, possibly catastrophic, outcomes. This implies constant monitoring of the species distribution and levels of establishment, as well as detailed knowledge about its biology to predict dissemination and viability under changing environmental conditions. Pre-screening kits for potential invasive species are valuable tools for policy makers, as they provide information about if and how management measures should be taken. The Freshwater Fish Invasiveness Scoring Kit (FISK) and the Aquatic Species Invasiveness Screening Kit (AS-ISK) have been suggested as reliable tools to assess the potential risk of a species becoming invasive. The present study highlights the spread of the non-native chameleon cichlid Australoheros facetus in several streams of the major river drainages in southern Portugal and compares the fish assemblages and ecological indices in two selected sites in the Vascão and Odelouca rivers. We reviewed the current knowledge on the distribution, physiology, and behavior of A. facetus, and applied the toolkits FISK v2 and AS-ISK to this species to evaluate whether the species should be classified as invasive in Portugal. Field data show high abundance of the species in most streams and dominance in specific hotspots. The scores reached by the kits (FISK v2: 23; AS-ISK: 37) places A. facetus as a species with high potential of invasiveness and support the recent inclusion of this species in the invasive species list in Portugal (Decree-Law 92/2019), but, most of all, highlights the importance of frequent updates in both the field monitoring and the legal regulation and watch lists of invasive organisms.
SUCCESS IN AUTOMATIC AND INTERACTIVE QUERY EXPANSION

This study explored how the expression of search facets and relevance feedback by users was related to search success in interactive and automatic query expansion in the course of the search process. Search success was measured both in the number of relevant documents retrieved and relevance scores of these items based on a four point scaling. Research design consisted of 26 users searching for four TREC topics in Okapi IR system, half using interactive and half automatic query expansion based on RF. The search logs were recorded, and the users filled in a questionnaire for each topic concerning various features of searching. The results showed that the exhaustivity of the query was the most significant predictor of search success, and that interactive expansion led to better search success than automatic one.
Clinical efficacy of core decompression combined with free fibular graft in the treatment of femoral head necrosis

Objective: To explore the clinical efficacy of core decompression combined with free fibular graft in the treatment of femoral head necrosis. Methods: A total of 90 patients with femoral head necrosis at phase II with 122 hip joints in total including 58 unilateral hip joints and 32 bilateral hip joints were enrolled. Sixty hip joints were treated with core decompression alone and the other 62 hip joints were treated with core decompression and free fibular graft in combination, and then they were studied retrospectively. The patients were compared in operation time, intraoperative blood loss and hospital stay, and their hip joint function, excellent and good rate before and after surgery were assessed using Harris score; their pain degree before and after surgery was assessed using visual analog score (VAS), and hip joint survival time was recorded based on a 5-year follow-up. Results: The two groups showed no difference in operation time and intraoperative blood loss (both P>0.05), and the observation group experienced significantly less hospitalization time than the control group (P<0.05). After surgery, the two groups showed significantly increased Harris score (both P<0.05), and the observation group showed significantly higher Harris score and significantly better excellent and good rate than the control group (both P<0.05). After surgery, the two groups showed significantly decreased VAS score, and the observation group showed significantly lower VAS score than the control group (both P<0.05). The observation group experienced significantly longer hip joint survival time than the control group (χ2 = 4.864, P = 0.027). Conclusion: For treatment of femoral head necrosis, core decompression combined with free fibular graft can effectively improve hip joint function, relieve postoperative pain, and prolong hip joint survival time. Core decompression combined with free fibular graft has been proved clinically efficient, so it is worthy of further clinical application.
Environmental Implications of Taiwanese Oolong Tea and the Opportunities of Impact Reduction

Tea is the second most consumed beverage globally, yet its environmental implications are largely unknown. To overcome this knowledge gap, life-cycle analysis was conducted aiming to quantify the environmental impacts associated with tea production and consumption. To achieve this objective, Oolong tea production in Taiwan was selected to investigate the life-cycle impact in global warming potential (GWP) and eutrophication potential (EP) associated with one serving of hot tea consumed in Taiwan domestically and the international market in the U.S. and U.K. The results indicate that each serving of Oolong tea can result in a total of 28.6 g CO2-equivalent of GWP and 0.09 g N-equivalent of EP. Over 52% of GWP and 44% of EP are associated with the tea’s cultivation, in which the application and production of agrochemicals accounts for 90% of GWP and 98% of EP. International consumption can increase GWP and EP by 19% and 26%, respectively, which is largely attributable to the change of cooking energy from natural gases to an electric-gas mixed scheme. The findings from this study articulate the environmental portfolio of Oolong tea. More importantly, we can identify opportunities to mitigate the environmental footprint of Oolong tea in order to advance future sustainability.

Mapping and Marker Assisted Selection

Sunflower chlorotic mottle virus (SuCMoV) is one of the most widely distributed viruses affecting sunflower (Helianthus annuus L.) in Argentina. Symptoms include yellow blotches, reduced and distorted leaves and plant stunting. SuCMoV-susceptible (20016) and tolerant (B-133) sunflower lines were mechanically inoculated with SuCMoV and total RNA was isolated from infected leaf tissue, amplified and hybridized to an Arabidopsis oligonucleotide-microarray containing 22,000 genes. The gene expression profile in inoculated plants from both lines was statistically different from non-inoculated leaf samples. Eighty-eight genes were differentially expressed in the tolerant sunflower line.
Paradigm for the development of a Lanna music curriculum in Higher Education in Northern Thailand

This article reviews the status of Lanna music in higher education, offering suggestions for the development of Lanna music in Northern Thai universities. The researcher adopts a phenomenological method, utilising data from a number of interviews (N=20) and observations. The results suggest that Lanna music in higher education plays a significant role in shaping the cultural identity of the community. This unique style of music is often taught as a core area of study, as an extension to existing music curricula, or is being offered elsewhere as a general subject of study pursued by non-music students. In the development of Lanna music curricula, the main objective is to sustain musical traditions, musical creativity and to promote professionalism in performance. The curriculum needs to consider the readiness of the elements, especially those pertaining to culture and community, which form the foundation of knowledge. The curriculum should develop learners on the basis of their interests and potentials and promote a local program which is attentive to local contexts. Finally, the curriculum should consider the diversity of culture and needs of the community.
Investigation of Mode of Action of Anti Bacterial Activity of Salacia Oblonga Extract Against Drug Resistant Pathogen

Salacia oblonga Wall belonging to family Celastraceae contains vital phytoconstituents and has been used since long for the treatment of diabetes, inflammation and burn wounds. S. oblonga ethyl acetate root extract was evaluated for antibacterial activity towards drug resistant pathogens Staphylococcus aureus, Pseudomonas aeruginosa and Klebsiella pneumoniae. Further 260 nm absorbing material was estimated in the control and treated cells. Interestingly 260 nm absorbance material is higher in the Staphylococcus aureus. Further the effect of the plant extract on drug resistant pathogen S. aureus was examined by scanning electron microscopy (SEM). SEM results have shown that treated bacterial cells have changed in morphology, size and reduced in number. Based on these results it can be concluded that S. oblonga extract acts on membrane of the drug resistant pathogen S. aureus.
Expression and distribution of all dopamine receptor subtypes (D 1 – D 5 ) in the mouse lumbar spinal cord: A real-time PCR and non-autoradiographic in situ hybridization study

Dopamine is a catecholaminergic neuromodulatory transmitter that acts through five molecularly-distinct G protein-coupled receptor subtypes (D 1 – D 5 ). In the mammalian spinal cord, dopaminergic axon collaterals arise predominantly from the A11 region of the dorsoposterior hypothalamus and project diffusely throughout the spinal neuraxis. Dopaminergic modulatory actions are implicated in sensory, motor and autonomic functions in the spinal cord but the expression properties of the different dopamine receptors in the spinal cord remain incomplete. Here we determined the presence and the regional distribution of all dopamine receptor subtypes in mouse spinal cord cells by means of quantitative real time PCR and digoxigenin-label in situ hybridization. Real-time PCR demonstrated that all dopamine receptors are expressed in the spinal cord with strongly dominant D 2 receptor expression, including in motoneurons and in the sensory encoding superficial dorsal horn (SDH). Laser Capture Microdissection (LCM) corroborated the predominance of D 2 receptor expression in SDH and motoneurons. In situ hybridization of lumbar cord revealed that expression for all dopamine receptors was largely in the gray matter, including motoneurons, and distributed diffusely in labeled cell subpopulations in most or all laminae. The highest incidence of cellular labeling was observed for D 2 and D 5 receptors, while the incidence of D 1 and D 3 receptor expression was least. We conclude that the expression and extensive postsynaptic distribution of all known dopamine receptors in spinal cord corresponds well with the broad descending dopaminergic projection territory supporting an widespread dopaminergic control over spinal neuronal systems. The dominant expression of D 2 receptors suggests a leading role for these receptors in dopaminergic actions on postsynaptic spinal neurons.
Do Regression-Adjusted Performance Measures for Workforce Development Programs Track Longer-Term Program Impacts? A Case Study for Job Corps

Since the 1970s, major workforce development programs administered by the U.S. Department of Labor have used performance management systems to measure program performance. Yet, there is scant evidence about the extent to which these performance measures are correlated with longer-term program impact (value-added) estimates. This article examines this issue using extensive data from a large-scale experimental evaluation of Job Corps, the nation’s largest training program for disadvantaged youths. At the time of the evaluation, most Job Corps performance measures did not account for differences in the characteristics of students served; since that time, performance measures have increasingly been adjusted for observable differences in student characteristics. Thus, we used detailed baseline survey, program intake, and local area data to regression adjust center performance measures and compared them to center-level impacts from the experiment. We find that while regression adjustment changed somewhat the center performance measures, they are not correlated with the impact estimates. Thus, there remain important unobserved differences between students attending different centers that are correlated with key participant outcomes.
A NARRATIVE INQUIRY ON HOW TEACHER PROFESSIONAL IDENTITY INFLUENCES TEACHER’S SCHOOL TYPE PREFERENCE

Some Indonesian English teachers prefer teaching in formal schools while some others favor non-formal schools more. This preference can be analyzed from the lense of teacher professional identity. In this study, the researcher tried to find out how teacher professional identity influences the school type teachers favor more. By conducting in-depth interviews to two non-formal school teachers from different regions in Indonesia, the researchers found out that job satisfaction, self-efficacy, occupational commitment, and occupational motivation are the factors influencing the participants’ professional identity the most. Job satisfaction could be seen, for example, in witnessing students’ progress more thoroughly; self-efficacy in being able to monitor their teaching performance; occupational commitment in teacher trainings provided by non-formal schools to build their career up; and occupational motivation in receiving manageable challenges from non-formal schools that trigger eagerness from the participants to work. Those findings could function as a reference for both formal and non-formal school stake holders in making sure that their schools could accommodate their teachers’ need in constructing their professional identity as it could influence teachers’ performance a lot.
Long range regional groundwater flow systems in the Northern Great Plains: (1) Groundwater flow directions within the Midale Formation at the Weyburn carbon sequestration site, Saskatchewan, Canada

Regional groundwater flow patterns have become a basis for judging the environmental effects of subsurface injection of CO2 in Alberta and Saskatchewan, and waste water disposal in the Athabasca region of Alberta. Presently, however, not much attention has been paid to the type of fluid dynamics used (the mathematical physics of engineering hydraulics with velocity potentials versus Hubbert’s force potentials and the integration of field data acquired). This paper evaluates the fluid dynamic concepts and field data presently in use, regionally and locally, at the well-known Weyburn CO2 sequestration test site in Saskatchewan. As an outcome it recommends an alteration in the concepts, types of investigations, and monitoring procedures in place. The new methods will actually improve the understanding of local and regional fluid dynamic processes, optimize management of injections, and permit the control of possible return flows. RÉSUMÉ Les patrons d’écoulement des eaux souterraines sont devenus la base pour évaluer les effets environnementaux de l’injection souterraine de CO2 en Alberta et en Saskatchewan, ainsi que des bassins d’eaux contaminées dans la région de l’Athabasca en Alberta. Jusqu’à présent, peu d’attention fut portée au type de dynamiques des fluides utilisé (la physique mécanique des milieux continus avec potentiel de vitesse par rapport aux forces potentielles d’Hubbert, ainsi que l’intégration des données de terrains acquises). Cet article évalue le concept de dynamique des fluides ainsi que les données de terrain présentement utilisées régionalement et localement au site d’essais de séquestration de CO2 de Weyburn en Saskatchewan. Il est suggéré d’apporter un changement dans le concept, le type d’investigations, et les procédures de surveillance présentement mises en place. Les nouvelles méthodes proposées vont permettre d’améliorer la connaissance des processus locaux et régionaux de dynamique des fluides, d’optimiser la gestion de l’injections, et permettre le control possible de retours d’écoulement.
The Role of Information Systems in Preventing Railway Suicide: A Service Value Co-creation Perspective

Suicide prevention is a major concern for railway operators internationally. This paper reports research in progress examining how information systems can facilitate passenger/organisational co-created value in terms of reducing the incidence of railway suicide. Thus, the objectives of this research are to: (1) explore and evaluate the effectiveness of using information systems interventions in a passenger railway servicescape, and (2) explore the relationship between these servicescape interventions and customer experience, and assess their impact on railway suicide prevention from a value co-creation perspective. While the focus of this research is preventing railway suicide, the information systems developed would also lend themselves to a wide range of additional railway security issues such as the detection and prevention of crime, terrorism, and potential misadventure incidents.
