The design and fatigue life analysis of many fabricated sheet metal components which operate in a hot gas path environment is made uncertain by the difficulty in predicting the gas dynamic forces to which the component will be subjected. This is particularly true for ducts which are exposed to minimal static loading such as inter-turbine ducts, which have little pressure drop across them but are subjected to highly non-uniform flow from the upstream turbine exit. Finite element analysis and static testing has revealed — that certain modal frequencies respond much more significantly than others and where these coincide with gas dynamic frequencies a resonance is set up and rapid and catastrophic failure will occur.Through a combination of analysis and engine testing it has been possible to identify the damaging gas dynamics and modal frequencies. This has enabled rules to be developed which assist in the design of such ducts to avoid high cycle fatigue failure.This paper describes the development of the design process and by means of a typical example shows its application and effect on the design of an inter-turbine duct.Copyright © 1997 by ASME

In this article, Lois Lamdin reviews current perceptions of 'employability' in the USA, the kind and extent of training sponsored by industry, and the difficulties perceived by industry in interacting with higher education in relation to training. She stresses the importance of recognizing the workplace as learning place, discusses the development and benefits of prior learning assessment, and sets out the importance of establishing a national credentialling system for the workforce, taking into account the variety of academic and non-academic ways learning is achieved. Finally, she describes the existing work of the Employee Growth and Development Programs of the Council for Adult and Experiential Learning, which demonstrate how business, unions, government, and higher education can work together to help respond to the crucial challenge of training and retraining a national workforce.


Taking the comprehensive soil erosion,water resource intimidation,water environment pollution and meteorological disasters into consideration,constructed is the evaluation system of environment sensitivity for Shengsi islands in Zhejiang Province.Using GIS technology and the method of combining positioning and quantitative analysis,the synthesized assessment of environment sensitivity of Shengsi is made.The assessment results reflect the basic island state of the environment which provides strong technical support for the rational exploitation of island resources.The results show:the sensitive areas reach 61.2% of the total land,very sensitive and highly sensitive account for 5.66% and 24.45%,moderately sensitive areas account for 31.09%,and slightly sensitive and sensitive areas account for 13.18% and 25.62%.


In the intercultural communication,it is always a case for both interlocutors,governed by different cultural background,social norms and social rules of speaking,to use the speaking strategy of their own in conversing with the other.They tend to render directly what is their own way of speaking into the target language,causing a misunderstanding of illocutionary act in the hearer and a loss of illocutionary force,as a result,leading to pragmatic failure.The present paper,from the perspective of intercultural communication,information theory and language teaching,endeavors to give a detailed discussion on the untranslatability of illocutionary force and the possibility of making the force translatable,meanwhile,ways to avoid it are also suggested.


Sphalerite [(Zn,Fe)S] from Mississippi Valley type (MVT), volcanogenic massive sulfide (VMS), and polymetallic vein (PMV) ore deposits show variable rates of dissolution and resulting aqueous metals concentrations under acid conditions. An important control on dissolution rates is solubilized iron that eventually produces Fe(III), a strong oxidant of sphalerite. VMS (high Fe and Cd) and PMV (high Fe and metals) sphalerite samples showed faster rates of sphalerite dissolution (10 -9 to 10 -10 mol/L/s Zn +2 ) and Fe solubilization (10 -9 to 10 -10 mol/L/s total Fe), and higher aqueous trace metals compared to MVT sphalerite that has low Fe and trace metals; these characteristics are manifested by slower rates of sphalerite dissolution (10 -10 to 10 -11 mol/L/s Zn +2 ) and Fe solubilization (10 -12 mol/L/s total Fe), and low aqueous metals compared to VMS and PMV samples. Aqueous concentrations of major (Fe, Zn) and trace (Cu, Cd, Pb, Mn) elements depended on the original composition and rate of dissolution of sphalerite. Fine-grained, high-Fe VMS sphalerite (6.7 wt.%) leached at pH 2-3 (25° C) produced dissolved Fe and Zn approaching 50 and 180 mg/L, respectively, within 1 week; Cu and Pb were 3 and 250 g/L, respectively. The same sphalerite leached at pH 4.0 or higher took two months to yield comparable concentrations. Coarse-grained VMS sphalerite leached for several months at a pH of 4.0 yielded only 100g/L Fe and 9.2 mg/L Zn. PMV sphalerite (4.2 wt.%) had a Zn solubilization rate and trace metal concentrations similar to the VMS sample, but a faster Fe solubilization rate (10 -8 mol/L/s Fetot). Low-iron sphalerite (0.2-0.3 wt.%) from MVT deposits produced Zn concentrations similar to the VMS sphalerite at pH 2.0 but lower concentrations at pH 4.0. At both pH values, aqueous Fe from the high-Fe VMS sample was 100 times that from the MVT sample. Trace metals showed a range of concentrations that generally depended on their original abundance in the solid and their solubilities in the acid solution. Because sphalerite from different ore deposits can be major sources of aqueous metals that may affect the composition of nearby surface and ground water, the potential metal contribution of non-pyritic minerals such as sphalerite should be a major consideration during all stages of economic development of an ore deposit.

Abstract: Today In This World Safety Of Miners Is Major Challenge. Miner's health and life is vulnerable to several critical issues, which includes not only the working environment, but also the after effect of it. Mining activities release harmful and toxic gases in turn exposing the associated workers into the danger of survival. This puts a lot of pressure on the mining industry. To increase the productivity and reduce the cost of mining along with consideration of the safety of workers, an innovative approach is required. Miner's health is in danger mainly because of the toxic gases which are very often released in underground mines. These gases cannot be detected easily by human senses. A real time monitoring system using wireless sensor network, which includes multiple sensors, is developed. This system monitors surrounding environmental parameters such as temperature, humidity and multiple toxic gases. This system also provides an early warning, which will be helpful to all miners present inside the mine to save their life before any casualty occurs. The system uses wireless sensor network technology to establish wireless sensor network. Keywords: html5, css3, Jscript.


During the period of January-June 2002, the main focus of this project was implementing and evaluating algorithms for embedding Earth-Mover Distance into the Euclidean space. Earth-mover distance (EMD) is a recently proposed metric for computing distance between features of images (see [EMD] and references therein). It was experimentally verified to capture well the perceptual notion of a difference between images, in fact much better than other well-known metrics (e.g., Euclidean distance between the feature vectors). The basic idea behind EMD is as follows. Assume that the features of an image are represented by a set of points in lowdimensional space Rd. For example, an image could be represented by a set of pixels, where each pixel is a point in 3-dimensional color space or texture space. The distance between two sets of points (representing two different images) is defined as the minimum amount of work needed to transform one set into another. Formally, this corresponds to the minimum weight matching between the two sets of points.

The number of cold atoms trapped in magneto-optical trap(MOT) can be derived from probe absorption signal. After the MOT is switched off, the cold cloud freely expands in gravitational field with an initial velocity distribution. So the measurement process can be described with the interaction model between the individual stationary two-level atom and single mode resonate laser. Absorption method can largely improved the measurement precision. In this paper we introduce the physical principle of measurement and demonstrate the whole experimental procedure in detail. The number of atoms trapped in our MOT, (8±0.3)×10 6 is measured in experiment. And the number of steady-state atoms and the lifetime of atom trapped in MOT was used to deduce the capture rate of MOT.

Background/Aims: We investigated the mechanism underlying anti-tumor necrosis factor-α (TNF-α) effects of epigallocatechin-3-gallate (EGCG) in human aortic endothelial cells. Methods: Tumor necrosis factor receptor 1 (TNFR1) was assessed by Western blot analysis. Cytosolic Ca2+ was measured using Fluo-4 AM. A disintegrin and metalloprotease 10 (ADAM10) was localized by immunofluorescence staining. Results: EGCG caused ectodomain shedding of TNFR1 within 30 min and attenuated TNF-α-induced endothelin-1 (ET-1) expression. EGCG-induced TNFR1 ectodomain shedding was prevented by BAPTA-AM (intracellular Ca2+ chelator), but not by the absence of extracellular Ca2+. In physiologic extracellular Ca2+ concentration, EGCG markedly increased cytosolic Ca2+. Even in the absence of extracellular Ca2+, EGCG raised cytosolic Ca2+, though less potently. siRNA depletion of ADAM10 prevented EGCG-induced ectodomain shedding of TNFR1 and also diminished the inhibitory effect of EGCG on TNF-α-induced ET-1 expression. EGCG caused translocation of ADAM10 to the plasma membrane, and this effect was prevented by BAPTA-AM. Besides extracellular Ca2+ influx, release of intracellular stored Ca2+ caused ADAM10-dependent ectodomain shedding of TNFR1. Conclusion: EGCG decreases the responsiveness of cells to TNF-α by causing ADAM10-dependent ectodomain shedding of TNFR1. This effect was attributed to its property to increase cytosolic Ca2+ through both extracellular Ca2+ influx and release of stored Ca2+.


The essence of the English Teaching is practice,which is embodied by activities.Communicational activities is one of the strongest points in University English Teaching.According to its aims and demands,we can divided the Communicational Activities into two main types:Activities In Class and? Activities After Class.The two types can reinforce the effect of English Teaching.


Interactive surfaces employ a variety of touch sensing technologies and implementations. Each of these offers unique strengths and limitations. An important metric for touch-sensitive surfaces is their tracking performance. This poster abstract presents some thoughts on a generic model of touch sensors and touch-sensitive surfaces. In it, a sensor is characterized by its range/precision dependency. This may allow to compare different touch-sensitive surfaces and predict performance of new sensor systems.


The house serves as a place to live, relaxing and enjoy it with the family. But most of the time the home is often only used as a place to sleep at night and left by their owners in the morning so as to make the house empty or unoccupied. With the state of the house that is always left behind by their owners, making home become vulnerable to danger, either security or safety hazard to the items contained in the house. This could be seen from the number of cases of theft and fire at an empty house being left by their owners. Busy homeowners to maintain and care for the house makes electrical equipment plugged become easily damaged and wasteful of energy such as light is always switched on when there is no person, with the intention that the house does not look empty so that the house is safe from theft, but in reality it no effect against theft.
To overcome that we need a home automation system so that the house can function properly. The system is called Smart Home System, which is a Smart Relay-assisted system that will provide all the comfortable, security, safety and energy savings which takes place automatically and programmed in a house. To ensure the safety of the theft, the system is designed to turn on the alarm and the lights automatically when detected burglaries in the house abandoned by their owners. And to ensure the safety and security of a fire, the system is designed to turn off all the electricity that goes to the lighting load and open the garage door automatically by detecting a wildfire through the fire sensor which makes the alarm sounds.

The article deals with the analyse of pedagogical possibilities of author's discipline «Musical local studies of Rivne region». The contest, task and aim of educational course are substantiated. The relevance is definited taking into account public enquiries and necessity of solving state problems. The author regards musical local history in two aspects: 1) as a branch of science and a contest of musical regional culture; 2) as an academic discipline in higher educational institution. The art of Rivne region is considered as a historical-ethnographic region of Volyn which was developed under the influence of interaction of Ukrainian culture and other ethnic groups living on this territory. Studying of peculiarities of Volyn region is necessary for reproduction of integrity of pedagogical and cultural processes. Abstract. Innovation processes are in conflict with the existing traditional training, however, there is a dialectical relationship between them, and it can be argued that in recent years two trends in the development of education have coexisted in teacher education − traditional and innovative. The modern educational program in the Republic of Uzbekistan adheres to a combination of new educational development trends with the obligatory continuation of the old, traditional teaching technology. An analysis of scientific and pedagogical research allows us to conclude that in pedagogical science there are theoretical prerequisites for studying the teacher's readiness for innovative activity as a factor that allows, on the one hand, to reduce the manifestation of the negative characteristics of his professional conservatism, and on the other, to update those that correspond to the optimal model of innovative pedagogical activity. Abstract . The peculiarities of the development of the high education in the counties of the Visegrad group are considered in this article. The classification of the educational tendencies on the general and leading, and the analysis of the conceptual tendencies of the professional preparation of the Masters of Philology in the universities helped to make the conclusion about the evolutional development of the high education in the countries of the Visegrad four. Each country member of the Visegrad four chose their own way therefore they enabled to preserve their language, culture, traditions and authenticity. The following tendencies are analyzed in this article: the preserving of the national language, literature and culture in the process of the reformation and using of the social and economic tasks of the EU; the ability of the reformation of the high education; formation of the competencies as a result of the teaching of the Masters; the formation of the European high education as the standard of the knowledge about Europe; involving the informational and communicational technologies; development of the international cooperation of the universities as a process of the internationalization of the education and increasing of the academic mobility of the Masters. Abstract. Modern society and the labor market poses a challenge for higher education to train future teachers and specialists of high innovative culture. The professional creative activity of a teacher in a modern university requires the need for a willingness to creative self-realization, based on the competencies to creatively develop and implement educational technologies, to be self-sufficient. The current stage is characterized by a desire to penetrate into the very foundations of didactic training of future specialists, as well as to identify opportunities for improving academic disciplines in the study and teaching of foreign languages. university the of Abstract. in this article, the author defines the concept of "intensification of didactic training of students", analyzes the views of psychologists and didactics on its main elements. The author considers the theory of intensification of the learning process in a pedagogical university as a leading professional-pedagogical category, the study of which is based on the laws and principles of pedagogy and psychology, is based on the personality-activity concept of human formation, the development trends of world science, technology and education. Emphasizing the great importance of previous studies to build a theory of intensification of the learning process in a pedagogical university, it is noted that they were relevant for the corresponding period of development of society and the state. However, the emergence of new types of educational institutions, the cooperation of higher educational institutions and vocational colleges, the creation of regional educational systems, the intensification of education in accordance with state educational standards, new curricula and programs, the prospects for the country's socio-economic development have determined the developmental features of the pedagogical university and professional college, academic lyceum and school. The problem of theoretical substantiation of the essence of the intensification of the learning process in a pedagogical university, the conditions necessary for its achievement, is currently not sufficiently developed. In addition, there was a certain contradiction between the social order of society for the preparation of a future teacher and the actual level of its readiness to perform a professional function. Abstract . The article explores the problem of forming the professional consciousness of the future teacher. A holistic approach to the understanding of professional consciousness, allowed to create a theoretical model and to distinguish its structural components. The focus is on functional (cognitive, emotional, motivational-purpose, operational) and structural (images: "Me-real", "Me-ideal" (professional), "Me-future" (development of professionalism), "Me- spiritual") components of professional consciousness, the development and formation of which is manifested in the gradual awareness of himself as a subject of future professional activity. In order to track the process of development and formation of individual components of professional consciousness in the educational and professional activity, the criteria and indicators are identified, which allow to fix the levels of professional consciousness formation: 1) formation of self-image, positive attitude towards oneself; 2) the desire for self-knowledge of his personality and his professional activity; 3) the formation in the mind of the idea of professionally important qualities, of professional activity; 4) the formation of the ability to organize their internal and external resources to achieve the goals of personal and professional development. It is argued that the development of these structural components of professional consciousness will contribute to the awareness and assimilation of practical activity, the formation of the personality of the future teacher as an independent subject, which is a prerequisite for becoming a self, the acquisition of personal meanings and self-knowledge. Abstract . This work refers to the problem of social-psychological adaptation at the age of junior school age. The goal of the research was to study influence of family upbringing style on the social-psychological adaptation of the younger school age. The hypothesis was the following: Family Upbringing Style affects the quality ofsocial-psychological adaptation of the 9-10 years old pupils. Data analysis demonstrated a significant connection between the authoritative style of the upbringing and the high quality of social-psychological adaptation of the pupil. Regressive analysis has proven that the style of authoritative upbringing is a positive predictor of the following psychological adaptation parameters:High sociometric status in class and high self-esteem-claim level. In addition, the authoritative style of upbringing is a negative predictor of anxiety level. Abstract.

The author outlines the main stages and tasks of each structural part of the study. The author also analyzes paradigm orientations, paradigm, methodological positions an


The development of biomechanically-accurate robotic arms is of high interest; in this paper we investigate an actuated spherical mechanism for biofidelic shoulder design. Given the high inertia of an extended arm, serial mechanisms were quickly discarded in favour of a parallel design. One particular design, the agile eye, was studied in depth due to multiple intrinsic advantages. However, no work was done regarding its capacities with higher inertia loads. Our objective is to characterise the behaviour of the agile eye in terms of speed, precision and input efforts when there is a load on the end effector. We developed the dynamic model of the robot to implement torque control with a PD controller. The system was then simulated for a few point to point trajectory conditions. The characterisation of the behaviour of the robot with a load on its end effector revealed that it reaches similar precision, with slightly slower speed depending on design choices but requires motors with power proportional to the expected load in comparison to when there is no mass on the end effector. These results can serve as design guidelines for anthropomorphic robotic arm/shoulder development.


RASopathies include a spectrum of disorders due to dysregulation of RAS/mitogen activated protein kinase pathway that plays an essential role in the control of the cell cycle and differentiation. As a consequence, its dysregulation has profound developmental consequences, in particular cardiac malformations. RASopathies with cardiac features are: Noonan syndrome, multiple lentigines syndrome, cardio-faciocutaneous syndrome, Costello syndrome, neurofibromatosis- 1, Legius syndrome, neurofibromatosis- Noonan syndrome. The former syndromes are associated with a high rate of cardiac involvement (60-85%) and 12 genes: PTPN11 , SOS1 , RAF1 , KRAS , HRAS , BRAF , MEK1 / MAP2K1 , MEK2 / MAP2K2 , NRAS , SHOC2 , CBL and SPRED1 . Although the majority of these diseases are readily distinguishable in clinical terms, an integrated imaging study of the cardiac condition associated to RASopathies helps to better define risk assessment, surveillance, and management of these patients.


Objective: The purpose of the study was to clarify contents of community life support provided by municipal public health nurses for mentally ill people. Methods: Semi-structured interviews were conducted with four public health nurses working in local government regarding the types of support necessary for keeping individuals with mental illness involved in community life. The interview data was then analyzed qualitatively. Results: As a result of our inductive analysis, 8 categories were identified. These are following categories; tart and concentration of care needs become obvious, confirmation and adjustment of medical continuation, prevention and measurement of symptom deterioration, confirmation and insuring of the family's help, maintenance of the family's economic stability, application and monitoring of care services, grasp and adjustment of relationships with persons who are close, support and promotion of independence. Conclusion:


In this paper we investigate the effectiveness of a novel resource for Multilingual Question Answering (QA). Such a resource consists of a set of multilingual pattern libraries for answer extraction and validation. In the spirit of the ongoing attempts to develop freely available resources for QA, we argue that the distribution and use of pattern libraries will contribute to make Multilingual QA a more feasible task.


Collective behaviour of pulse-coupled oscillators has been investigated widely. As an example of pulse-coupled networks, fireflies display many kinds of flashing patterns. Mirollo and Strogatz (1990 SIAM J. Appl. Math. 50 1645–62) proposed a pulse-coupled oscillator model to explain the synchronization of South East Asian fireflies (Pteroptyx malaccae). However, transmission delays were not considered in their model. In fact, the presence of transmission delays can lead to desychronization. In this paper, pulse-coupled oscillator networks with delayed excitatory coupling are studied. Our main result is that under reasonable assumptions, pulse-coupled oscillator networks with delayed excitatory coupling cannot achieve complete synchronization, which can explain why another species of fireflies (Photinus pyralis) rarely synchronizes flashing. Finally, two numerical simulations are given. In the first simulation, we illustrate that even if all the initial phases are very close to each other, there could still be big variations in the times to process the pulses in the pipeline. It implies that asymptotical synchronization typically also cannot be achieved. In the second simulation, we exhibit a phenomenon of clustering synchronization.


The paper describes the indirect method of obtaining the information on wheel pair skidding. The method is based on using a special filtration scheme which filters the estimated resistive torque and highlights the signal which is proportional to wheel pair skidding. The work introduces as well the imitation modeling results. The modeling results were analyzed by comparing the linear velocities of wheel pair and electric locomotive in different modes. The method helps to increase energy efficiency of acceleration and braking processes of mobile composition with mine electric locomotive.


Soil resistivity is usually measured at the selected site either for new installation or in the existing grounding system. In this paper, soil resistivity test has been done to study the soil resistivity around the 33 kV substation according to IEEE 81-1983 standard. A factory site located in Kulim Hi-tech, Malaysia has been selected to research on the soil resistivity. The soil resistance measured in this study is then be calculated in using the soil resistivity formula. The soil resistivity shows that the longer the distance between rods, the lower the resistivity of soil due to larger soil volume. The lowest soil resistivity around the substation is 3.454 Ω.m, which is on the left side of the substation with a distance of 5 meters between the rods followed by front side with 15.71 Ω.m, right side with 34.243 Ω.m and backside with 45.239 Ω.m. While the highest soil resistivity is 176.306 Ω.m on the right side of the substation with a 2-meter distance between each rod.


Fumarate-Alumoxane nanoparticles (Fum-ANPs) incorporated PES nanofiltration membrane was fabricated via phase inversion to achieve favorable performance as an antifouling nanofiltration membrane for dye removal. To investigate the effect of the Fum-ANPs on nanofiltration performance, pure water flux and water contact angle measurements were carried out. FTIR spectra of the Fum-ANPs revealed that the carboxylate and hydroxyl functional groups were created on the surface of Fum-ANPs. The strong affinity of Fum-ANPs functionalities with water molecules made the membrane surface more hydrophilic. Hence, this membrane sample had a higher pure water flux than the bare one. Zeta potential data showed that the Fum-ANPs blended PES membrane was negatively charged at a pH value of 6, which is favorable for negatively charged solute rejection. For investigating the antifouling behavior of the membranes, powder milk solution (8 g/l) were analyzed using a dead-end filtration apparatus. The results obtained from fouling analysis clearly demonstrated that the introduction of Fum-ANPs in the membrane matrix ameliorated the antifouling behavior of the resulting membrane. To study the performance of the Fum-ANPs incorporated PES membrane rejection of Direct red 16 dye was tested. The Direct red 16 rejection with the Fum-ANPs blended PES membrane was 99% while it was 88.2% for the bare membrane sample

The EEG of ten elective abdominal surgery patients was studied during halothane anaesthesia. The EEG was analysed by compressed spectral array. The total power and various power bands were analysed. Anaesthesia was induced by mask with halothane in air. EEG analysis was performed from the data collected before induction and during anaesthesia at steady states of 1 MAC, 1.5 MAC, and 2 MAC. The correlation between deepening anaesthesia and power values was strongest in the 10–14 Hz band power and in the 18–32 Hz band power. This study confirms the usefulness of high frequency power in estimating the effect of halothane in patients.


The daily variations in the underwater irradiance spectra at different depths were determined using a combination of in situ data and model calculations. The spectra of the attenuation depth (relevant in optical remote sensing) were derived from


Health disease related to indoor air quality such as sick building syndrome is believed to cause a low performance of building occupants. Proper management of indoor air quality according to established code of practice can prevent the exposure to indoor air contaminants which will result in IAQ health related diseases. The Industrial Code of Practice on Indoor Air Quality 2010 provides guidance for managing indoor air quality problem and set the minimum standard for the selected IAQ parameters. It is believed that most of the industries already recognized the standard but unavailability of effective technique had delay the implementation of this standard. This research study is conducted to introduce a systematic technique manage indoor air quality problem in industries to achieve acceptable level of indoor air as well as to prevent the presence of sick building syndrome and other IAQ related health disease. This study covered analysis of requirements of the code of practice, development of framework and database management system as well as concept validation through case study from real data of an industry building. Implementation of this technique will help employer to control the presence of indoor air contaminants and minimize the case of IAQ related health disease.


In the habitual expression of a language,"sexual discrimination" refers to the discrimination of women in addressing terms.This paper probes into such a discrimination reflected in the addressing terms in the English and Chinese languages.It finds that in the English language,addressing terms of men tend to be favorable while those of women tend to be derogatory.In the Chinese language,however,"sexual discrimination" in addressing terms reflects the influence of the traditional Chinese culture and it results from the difference of social status between men and women.


Because of the "Semantic gab" problem in the traditional CBIR(content-based image retrieval) systems,they are not fit in some special areas.The appearance of Image-Semantic-Annotation can effectively resolve this problem.This paper represents a method that first uses the Normalized Cuts to cut the image into several areas and then extract the low-level features,last use BP neural network algorithm to learn the relations between the areas and the annotation words.The experiment's results proved this method is valid and efficient.


The present work concerns the influence of surface (machined, as-built) on the fatigue resistance of AlSi10Mg produced by a powder-bed laser process. The competition between defects and surface roughness is assessed by using Kitagawa-type diagrams. Samples are printed along three directions: 0°, 45° and 90°. After axial fatigue tests with a load ratio of R = −1, all the fracture surfaces are carefully analysed. The initiation sites can be (i) a defect, (ii) the surface roughness, (iii) the surface ripple. The results indicate that ground surfaces lead to the same fatigue life as as-built surfaces. It is also shown that T6 treatment improves the fatigue resistance. However, when specimen surfaces are as-built or ground, it is difficult to correlate the fatigue results with 'isolated defect size analysis' neither roughness parameter for an as-built surface. Therefore, microstructure, residual stresses or multiple initiation should be further analysed to understand the results.


For various applications, such as object recognition or tracking and especially when the object is partly occluded or articulated, 3D information is crucial for the robustness of the application. A recently developed sensor to aquire distance information is based on the Photo Mixer Device (PMD) technique. This article presents an easy but accurate data acquisition method for data evaluation of a customary sensor. Data evaluation focuses on the detection of the overand underexposured data under consideration of objects with two


In two previous papers, I introduced SuperSpreader (SS) epidemic models, offered some theoretical discussion of prevention issues, and fitted some models to data derived from published accounts of the ongoing MERS epidemic (concluding that a pandemic is likely). Continuing on this theme, here I discuss prediction: whether, in a disease outbreak driven by superspreader events, a rigorous decision point---meaning a declaration that a pandemic is imminent---can be defined. I show that all sources of prediction bias contribute to generating false negatives (i.e., discounting the chance of a pandemic when it is looming or has already started). Nevertheless, the statistical difficulties can be overcome by improved data gathering and use of known techniques that decrease bias. One peculiarity of the SS epidemic is that the prediction can sometimes be made long before the actual pandemic onset, generating lead time to alert the medical community and the public. Thus modeling is useful to overcome a false sense of security arising from the long "kindling times" characteristic of SS epidemics and certain political/psychological factors, as well as improve the public health response.


Applying the subordination theorem of J. E. Littlewood[1], and Lemma of S. S. Miller and P. T. Monanu[2] to certain analytic functions, we show an integral means inequality. Further, we obtain an integral means inequality for the first derivative.


Occlusive vascular disease is the major cause of death in western society and is strongly linked with consumption of specific fatty acids. This thesis investigates the extent to which dietary arachidonic acid alters the production of eicosanoid compounds and their subsequent effect on blood coagulation and thrombogenesis. It was found that increased levels of dietary arachidonic acid caused a rise in thrombosis potential, but this trend was reversed by the simultaneous consumption of omega-3 fatty acids.


We give a new proof of the string topology structure of a compact oriented surface of genus g greater than or equal to 2, using elementary algebraic topology. This reproves the result of Vaintrob.


The purpose of this study was to measure Newfoundland teachers' perceptions of the relationship between formative teacher evaluation practices and the overall quality of the evaluation experience, the perceived levels of teachers' commitment to their schools and teachers' professional involvement in their work and professional development. At the time of this study, there were 29 school districts (since reduced to 10), with each having their own teacher evaluation policies. The Newfoundland and Labrador Teachers' Association (NLTA) has placed an emphasis on formative teacher evaluation since 1982; however, a review of policies from districts across the province indicated that formative teacher evaluation practices are carried out to varying degrees. -- Data were collected from a random sample of Newfoundland teachers (n=229) and subjected to multiple regression analysis. This study found that statistically positive relationships existed between the use of formative teacher evaluation practices, the overall quality of the teacher evaluation experience, teacher commitment, and professional involvement (p < .0005). All three of the hypotheses chosen for the study were supported. -- The results suggest that variations of practice existed between individual school's and/or district's teacher evaluation policies. Some teachers reported that while their school districts had policies that promoted formative teacher evaluation practice, in reality, these policies were not emphasized in practice. As well most teachers reported that they were evaluated by either their superintendent/assistant superintendent and/or their principal/vice principal; however, the majority of teachers felt that the best person to evaluate them and to determine the degree of teacher growth and professionalism was either themselves or a fellow teacher which may suggest that teachers prefer formative teacher evaluation practices. -- The results of this study reinforce the validity of formative teacher evaluation practices as a viable alternative for teacher evaluation in the province of Newfoundland and Labrador. These findings suggest that, if formative teacher evaluation policies were chosen for implementation, some school districts and/or individual schools would need major changes to their evaluation policies. However, in schools and districts where formative evaluation policies already exist, some would only need to be reviewed and improved upon. The same is also true for any provincial teacher evaluation model that may be considered by government and/or the Newfoundland and Labrador Teachers' Association. These results support other studies completed in this area and suggest that formative teacher evaluation may lead to improved teaching through increased teacher commitment and professional development. The research literature reviewed for this study suggested that such a result would lead to improved achievement by students and greater accountability by teachers which is desired by the public.


We present a case study for designing a fleet of modular, unmanned aerial and ground vehicles (UAV and UGV) working cooperatively in a disaster relief mission. The study is motivated by the desire to explore the potential benefits of modularity coupled with autonomy. For example, as a result of the synergy between autonomy and modularity at the fleet level, autonomous battery replacement can extend the operation range of aerial vehicles. The study follows a simplified design process from problem definition to prototyping of the modular aerial vehicle as a first step in developing the fleet.


Introduction: Internationally governments have promoted general practices and community pharmacy working together more closely. Despite examples of co-location, this has not been particularly successful for a number of reasons, including issues of territoriality. There is growing interest in clinical pharmacists working in, and for, general practices. Practice change: This is a change in the model of service delivery with the clinical pharmacist working within the multidisciplinary team of a health care home, and independent of a community pharmacy. This paper explores the changes occurring in the UK and Australia, and presents information of the roles and activities of the fledging clinical advisory pharmacist workforce in New Zealand. It includes the roles of prescribing pharmacists in primary care, using a collaborative prescribing model. A survey of these pharmacists provides information on their roles and contributions to patient care, and creates opportunities for other health care homes to incorporate this resource into their practice. Aim and theory of change: The aim of this change is to allow clinical advisory pharmacists, who by definition have postgraduate qualifications, to work to top-of-scope though working in the health care home, helping to reduce drug-related morbidity and mortality and therefore helping optimise medicines-related health outcomes. The theory of change incorporates the concepts of the power / process and medical dominance models. This requires exposure to the new service, but additionally it has required recognition that the independent clinical advisory pharmacists have a different set of knowledge and skills. Targeted populations and stakeholders: Most of the clinical advisory pharmacists in New Zealand are working in practices with vulnerable populations to improve access to optimal pharmacotherapy. This has been expanding, particularly over the last three years. Highlights: The highlight of this service is the expansion and growing workforce with acceptance of the role of clinical advisory pharmacists within a health care home team and utilising their skills to improve person and whanau care. Evaluations of the different services has shown beneficial outcomes. Sustainability, transferability: With the changing workforce and increasing multidisciplinary teams in health care homes, this model of clinical pharmacist service delivery is very transferable, although requires a transfer of funding and investment for five years to establish it fully and achieve a critical mass. Conclusions: Independent clinical advisory and prescribing pharmacists are a viable way of integrating services into the health care home. We can learn from international evidence, but also the growing evidence in New Zealand. Lessons learnt:The clinical advisory and prescribing pharmacists bring a different skill set and focus into the health care home, but exposure is required to help understand the benefits achieved.

This commentary will outline the circumstances leading to the destruction of the Juukan Caves by Rio Tinto in May 2020. Secondly, it explains how the existing complexities of the legal framework designed to protect Indigenous cultural heritage resulted in the "legal" destruction of the Juukan Caves. The third part considers whether this incident may encourage positive changes in the relationship between Aboriginal peoples and resource companies which is reflected in law and governance. Recommendations from an ongoing public inquiry into the circumstances surrounding the destruction may begin this process of healing for the impacted Aboriginal community providing some pathways for change.


The study examined how LGBTQ individuals negotiate their identities in the Malaysian heteronormative society using
 the Discourse-Historical Approach. In-depth interviews were carried out with 13 LGBTQ individuals to find out the discursive
 strategies they used in describing the triggers for coming out, their experiences, and the reasons for their struggles. The
 analysis of the interview data showed that the participants used the "destiny" and "rights" arguments to counter the "legal",
 "religious" and "traditional values" arguments used by heterosexuals to reject them. Referents and personal pronouns were
 selectively used by LGBTQ participants to present different perspectives, "us" versus "them" (heterosexuals), "I" and other LGBTQ
 individuals, and "I" versus "they" or "you" (other sexual orientations). The findings have implications that are relevant to
 mitigation of LGBTQ identities in contexts which have strong heteronormative norms due to legal, religion and traditional
 values.


This paper tries to explore the different ways in which online learning platforms can be used to address learning challenges for students at the University of Mauritius. The main challenges identified were in the form of large number of students in class, the lecturer being unable to give individual attention to each student and the inability to cover all material in the given time frame. The main problems encountered by students were in the form of inability to ask questions due to the large class size, lack of interaction with the lecturer and in some cases the lack of supplementary material. Findings indicate that online learning platforms can indeed be used to address learning challenges so that the online learning platforms supplement and complement traditional face-to-face lectures.


Dear editor, Armuzzi and Pugliesi have recently published an editorial about the HOT‐TOPIC trial. In the current study, Lansdorp et al. reported the long‐term (week 60) follow‐up of 20 Crohn's disease patients with perianal fistulas treated with 40 daily sessions of hyperbaric oxygen therapy, for a total of 8 weeks. The authors raised some questions, such as: (I) the direct cost for the health/insurance system; (II) the indirect cost for patients, treated for 40 working days; and (III) the hyperbaric oxygen therapy chambers availability across the inflammatory bowel disease (IBD) centres. The shift fromevidence‐basedmedicine to value‐basedhealthcare has been happening over the past years, a necessary change to keep healthcare costs sustainable over the coming decades. Crohn's disease is a lifelong diseasewith a high healthcare cost burden andwhere high‐ cost drugs are required to achieveoptimal outcomes.PerianalCrohn's disease is themost difficult phenotype to treat and it is associatedwith a poor quality of life and with poorer response to medical and surgical therapies. Current treatment options are limited and the best medical and surgical therapies result in only about a third of patients remaining in remission at 1 year on maintenance treatment and sustained healing is often not achieved. The authors mentioned that the greatest limitation of this study is the absence of a control group to really assess the effect of the additive treatment with hyperbaric oxygen therapy. This should definitely be an area of focus for future research, although the difficulties in performing controlled trials for any additional therapy in refractory (fistula) patients should be taken into account. Even if blinding would be possible, the interpretation of results will be hampered as only patients interested in hyperbaric oxygen will participate. This inherent difficulty of patient preference will result in limited external validity. The authors ask what the direct and indirect costs of hyperbaric oxygen are. In the Netherlands, where the HOT‐TOPIC trial was executed, 40 sessions of hyperbaric oxygen therapy currently cost around 8.500 euros. The costs vary from country to country. In Brazil, for example, the cost of 40 sessions is 3.200 euros. Indirect costs that might occur are travel expenses to and from the chamber, and sick days from work (if applicable in this chronically ill group of patients). The extend of these costs are highly variable: for example, some patients are able to continue their work during treatment like normal, while others are not. However, these costs should be considered in a wider context. What are the direct and the indirect expenses for the health/insurance system of patients with active perianal Crohn's disease? This phenotype is associated with high health care consumption due to frequent consultations, hospitalization, multiple perianal surgeries, risk of permanent ostomy, optimization of costly biologicals and biological failure. The authors mention the ADMIRE trial, concerning mesenchymal stem cells (Darvadstrocel). The European Medicines Agency recently approved this treatment for perianal Crohn's disease, with a projected cost in the Netherlands of around 15.000 euros per 30 million cells. The dose that was used in the ADMIRE trial was 120 million cells, adding up to 60.000 euros per treatment. The ADMIRE trial reported remission (as defined as clinical closure of external openings and no collections larger than 2 cm on MRI) with Darvadstrocel in 14/25 (56%) patients, versus 6/15 (40%) patients in the control group. However, as the authors point out, both groups also had fistula curettage, surgical drainage, and closure of the internal orifice. None of these procedures were performed in the HOT‐TOPIC trial. For future research adding these procedures to the protocol might even further improve the outcome of patients undergoing hyperbaric oxygen therapy. Finally, we agree that the hyperbaric oxygen therapy chambers availability across the IBD centres is a hard step to overcome. In the Netherlands there are 11 hyperbaric chambers, allowing for adequate availability, but this is not the case in all parts of theworld. In Brazil, for example, there are 140 hyperbaric chambers, distributed throughout all regions and capitals. Brazil is a continental country with a higher concentration of hyperbaric chambers in the South and Southeast regions. In Brazil, there is a lack of access to hyperbaricmedicine in the public health system, and, in most cases, access is guaranteed for patients with health plans. Future studies are required to evaluate the real adjunctive benefit and the cost effectiveness assessment of hyperbaric oxygen therapy in patients with perianal Crohn's disease. Until then, we need to offer the best we have to our patients, balancing the pros and cons of each treatment based on evidence, individualizing the conduct to define the best therapy for each patient.

We study effects of the scale-invariant hidden sector, the unparticle, proposed by Georgi, on top spin correlation at the Large Hadron Collider. Assuming no flavor-changing interaction between the unparticles and the standard model particles, the top-antitop quark pair production process arises through virtual unparticle exchanges in the s channel, in addition to the standard model processes. In particular, we consider contributions of scalar and vector unparticles and find that these make sizable deviations of the top spin correlation from the standard model one.


A 3‐layered composite plate is innovatively fabricated via composite rolling of 1.6 wt% B stainless steel surrounded by two layers of boron‐free steels. The tensile properties of composite and non‐composite plates are comparatively tested and analyzed. Besides, the microstructure evolution of the investigated plates is characterized in detail. It is found that the composite specimens exhibit higher tensile elongation comparing with that of non‐composite specimens. Specifically, the engineering strain of the 1050 °C × 30 min solution‐treated specimens reaches to 12.5 ± 0.8% which is 2.5–3.0 times as high as that of non‐composite specimens. In addition, the as‐cast lamellar borides break into bar‐shaped structures in hot rolled plates, however, their morphology and distribution hardly change after solution treatment. Besides, the transition regions between the core and clad layers are formed and characterized by medium‐sized recrystallized grains and fine borides in the solution‐treated composite specimens. The enhancement mechanism of tensile elongation is mainly analyzed in term of the geometrical restriction of necking in the composite plate during tensile deformation. This paper provides a promising method to effectively enhance the tensile fracture elongation for these metallic materials with poor plasticity like high borated stainless steels.


This chapter argues that English and Welsh insolvency law provisions must be perfected so that insolvent charities are administered to ensure that general charitable purposes continue to be achieved despite technical insolvency. The survival of general charitable purposes should usurp all other stakeholder interests, including those of the creditors. By drawing an analogy between the "rescue culture" in English and Welsh insolvency law and the cy-pres doctrine in charity law this chapter argues that the administration procedure can best achieve the continuation of general charitable purposes. If administration and its use is perfected towards this aim using "adapted cy-pres" the underlying theoretical underpinnings of charity law and insolvency law will be unified for the ongoing benefit of society.

Sidegating characteristics of AlGaAs/GaAs heterostructure field‐effect transistors, fabricated on molecular‐beam epitaxially grown layers, were investigated with emphasis on the material properties. A systematic analyses of the epitaxial layers concluded with the identification of the substrate–superlattice‐buffer‐layer interface as the predominant cause of the sidegating effect. Remnant carbon contamination on the GaAs surface was found to produce a p‐type, conducting interfacial region. Controlled oxidation of the carbon on the wafers was accomplished using ultraviolet radiation. This oxide was desorbed in situ before epitaxial growth. Secondary‐ion‐mass spectroscopy was employed to estimate the carbon concentration at the substrate–epitaxial‐layer interface for standard cleaned and ultraviolet‐ozone‐treated wafers. The carbon concentration of the interfacial region decreased by two orders of magnitude for the wafers exposed to the ultraviolet radiation. Hall‐effect measurements of standard cleaned and ...


A kit and a method for diagnosing a porcine epidemic diarrhea virus antigen are provided to diagnose the antigen conveniently and rapidly without a special testing equipment in a farm or a laboratory field. A kit for diagnosing a porcine epidemic diarrhea virus antigen is characterized in that a conjugate of a monoclonal antibody 6G15(deposition no. KCTC 10996BP) coupled to nucleocapside 58kDa of an epidemic diarrhea virus and a gold particle is attached to a reaction position of the porcine epidemic diarrhea virus antigen on a strip and a monoclonal antibody 9D11(deposition no. KCTC 10997BP) is attached to a position different from the coupling portion of the porcine epidemic diarrhea virus antigen and the monoclonal antibody 6G15. A method for diagnosing the porcine epidemic diarrhea virus antigen comprises the steps of: (a) loading a sample onto a detection pad on a strip; (b) reacting the conjugate of the monoclonal antibody 6G15 coupled to nucleocapside 58kDa of the epidemic diarrhea virus and the gold particle with the porcine epidemic diarrhea virus antigen in the sample; and (c) reacting the porcine epidemic diarrhea virus antigen, the monoclonal antibody 9D11 and the reaction product obtained from the step(b).


Expression of genes found in the brains of autism, bipolar, and schizophrenia patients identified as overlapping. The overlap is a state in which the values of genes are similar. This paper aims to determine the best performance of support vector machines algorithm in classifying autism, bipolar, and schizophrenia based on the expression of genes using genome-wide association studies data. Using three support vector machine kernels, this study evaluates the performance of gaussian, laplacian, and sigmoid for genome-wide association studies datasets. The datasets were obtained from Psychiatric Genomics Consortium publications, where 660 data were taken with each disorder consisting of 220 data. This study proposes an optimal kernel for one-against-one and one-against-all multiclass support vector machine, and the performance is evaluated using accuracy. The study results show that the Gaussian kernel has the best accuracy performance compared to other support vector machines kernels in classifying genome-wide association studies data of autism, bipolar, and schizophrenia as early diagnosis.

Metamaterial-based composite right/left-handed transmission lines are used in the design of fixed frequency and tunable ring resonators. Under specific design conditions, the first two resonant modes can be narrowly spaced. A simple passive band-pass filter is demonstrated at 2.92 GHz with a bandwidth of about 9% using this concept. This type of design is also used as a tunable resonator and a tuning range of 30% is demonstrated.


We propose a new matrix pencil based approach for design of state-feedback and output-feedback stabilizing controllers for a general class of uncertain nonlinear strict-feedback-like systems. While the dynamic controller structure is based on the dual dynamic high-gain scaling based approach, we cast the design procedure within a general matrix pencil structure unlike prior results that utilized conservative algebraic bounds of terms arising in Lyapunov inequalities. The design freedoms in the dynamic controller are extracted in terms of generalized eigenvalues associated with matrix pencils formulated to capture the detailed structures (locations of uncertain terms in the system dynamics and their state dependences) of bounds in the Lyapunov analysis. The proposed approach enables efficient computation of non-conservative bounds with reduced algebraic complexity and enhances feasibility of application of the dual dynamic high-gain scaling based control designs. The proposed approach is developed under both the state-feedback and output-feedback cases and the efficacy of the approach is demonstrated through simulation studies on a numerical example.


On 8 January 2009, Professor Esther Duflo, holder of the new Chair "Knowledge against Poverty", delivered her inaugural lecture to a particularly large audience at the College de France. Thousands of kilometres away, in Antananarivo, Bamako, Rabat, Sofia and Yaounde, academics and development actors gathered together on the "digital campuses" of the Agence Universitaire de la Francophonie (AUF) to follow this inaugural lecture live, on line, on the College de France website, and to debate amo...


The purpose of the study was the precise delineation and mapping of alluvial fans, locating in mountainous areas of Northern Greece, by the use of: a) LANDSAT/TM and TERRA/ASTER satellite images (pixel size 30 m and 15-90 m respectively), b) topographic and geological maps and c) ground truth procedure (visiting the test sites). The digital processing of the satellite images was performed with EASI/PACE software. False Colour Composite (FCC) images, that helped to the better delineation of the fans, were derived by various image processing techniques, such as contrast stretching, ratioing, Principal Components Analysis (PCA),etc. The above processed images were imported into a Geographical Information System (GIS) and they were georeferenced to UTM Projection System. Next, the delineated (on the images) fans were digitized and overlaid to topographic and geological maps. From the above procedure and in comparison to ground-truth observations, it was concluded that the boundaries of the alluvial fans appear more precisely on the satellite images than in geological and topographic maps. The results of this study could be useful to geomorphologists dealing with morphological study and analysis of the alluvial fans. Also, they could be helpful to the improvement and updating of the present geological maps, by defining the boundaries of the fans mere precisely. Finally, conclusions can be drawn concerning the sorting of the materials comprising the fans. This information could be useful to hydrogeologists, since the alluvial fans are usually rich in water content.


Natural regeneration ability of plant communities in different succession stages in Guizhou typical Karst area were studied by indexes reflecting the community regeneration characteristics,such as density of soil seed bank,density of seedling bank,density of seed trees,and other 2 key environmental factors which reflected the impact on changes of community regeneration bank as thickness of soil layer and community coverage in the sampling sites,to explore the regeneration ability and their influencing factors,and to provide theoretical basis for vegetation restoration and integrated management in Guizhou rocky desertification Karst areas.The results showed that:1) The order of natural regeneration ability of communities was shrub community stage arbor forest stage shrub-herbaceous communities stage herbaceous communities stage rocky desertification stage;2)The impact of regeneration bank on natural regeneration ability of community was far greater than that of the environmental factors,especially in shrub community stage and arbor forest stage;3)Environmental factors had greater impact on natural regeneration ability in herbaceous communities stage;4)Natural regeneration ability of community in rocky desertification stage was not only restricted badly by regeneration bank but also environmental factors.


The paper examines the interactional construction and management of affect in everyday family interactions videorecorded at home. Relying on a corpus of ethnographic data collected from 8 Italian families, the aim of the paper is to show how discourse and sequences of actions work in concert to manage the quality and intensity of affect in the parent-child interaction. In particular, the paper focuses on episodes of divergence and conflict between the parents and their children. Analyses show how the use of formulations (Heritage & Watson, 1979), together with changes in the participant framework (Goffman, 1981), including the presence of the researchers, help the parents to exit from a potentially high degree of emotional involvement and prevent threats of the family face (Goffman, 1959). Finally, the author discusses how affect in discourse, besides being identified as linguistic (or, also, para- and non- linguistic) markers, needs to be examined on a sequential basis, i.e., as it develops (and changes) across turns, actions and activities performed in talk.

We have solved the x-ray crystal structure of the yeast enzyme inorganic pyrophosphatase. X-ray data was recorded at -50/sup 0/C by rotation photography, the intensities determined using OSCAR, and the intensity data scaled by Fourier-Bessel scaling. The phases were determined by the SIR-SAS technique as supplemented by density modification and 2-fold symmetry averaging.


We determine the dynamical structure factors of two gapped correlated electron systems, namely the Ising model in a strong transverse field and the two-leg spin-1/2 Heisenberg ladder in the limit of strong rung coupling. We consider the low-temperature limit, employing a variety of analytical and numerical techniques. The coherent modes
of single-particle excitations, which are delta functions at zero temperature, are shown
to broaden asymmetrically in energy with increasing temperature.
Firstly, we apply a low-temperature "resummation" inspired by the Dyson equation to
a linked-cluster expansion of the two-leg Heisenberg ladder. We include matrix elements
to second order in the interaction between states containing up to two particles. A
low-frequency response similar to the "Villain mode" is also observed.
Next, we apply a cumulant expansion technique to the transverse field Ising model.
We resolve the issue of negative spectral weight caused by double pole in the leading
self-energy diagram by including a resummation of terms obtained from the six-point
function, demonstrating that the perturbation series in 2n-spin correlation functions can
be extended to higher orders. The result generalises to higher dimensions and the analytic calculation is compared to a numerical Pade approximant. We outline the extension of this method to the strong coupling ladder.
Finally, we compare the previous results to numerical data obtained by full diagonalisation of finite chains and numerical evaluation of the Pfaffian, a method specific to the transverse field Ising chain. The latter method is used for a phenomenological study of the asymmetric broadening as well as an evaluation of fitting functions for the broadened lineshapes.


In a collaborative risk management scenario, project stakeholders often need natural forms of recording and reusing past risk management experiences so that they could better assess whether there are threats to the goals of new projects. The contribution of this paper is to propose an enhanced case-based reasoning (CBR) approach to support project participants to exploit such experiences which are here expressed as collaborative risk management discussion cases. The paper shows how these debates are structured through the exploitation of a dialogue game protocol for risk management. Then, it discusses how users can utilize queries based on facts and arguments so that past risk discussion cases could be retrieved from a case base. Attention is also given to case-based explanation templates, which are relevant for the understanding of key moves of argumentation in debate trees recorded in such enhanced cases retrieved. To demonstrate the practical utility of this approach, a case study involving the collaborative experience-based risk management of a software project is discussed. Keywords-component: Case-Based Reasoning; Collaborative Risk Management Tool; Dialogue Game; Argumentation.


Modular multilevel converter(MMC) is a multilevel converter with novel topology.MMC topology is based on cascade connection of chopper-cells per leg.Therefore,how to balance voltages of capacitors in chopper-cells becomes a critical problem to research on.This paper introduces two loops to depress loop current and meanwhile control average voltage,and combines nearest level control with voltage sort control as well.Based on the control method presented in this paper,voltage sort control is improved to reduce switching operation and switching losses.MMC inverter side model with 20 cells each leg is realized by MATLAB/Simulink.Traditional balancing control and improved one are compared.The simulation results,including MMC output waveform,capacitor voltage waveform and switching signal,demonstrate the validation of the control method.


During cementing operation, it is critical to determine the location of cement slurry between the casing and formation, depth of the circulation losses and fluid loss, setting of cement in place and performance of the cement after hardening. Recent case studies on oil well failures have clearly identified some of the cementing issues that resulted in various types of delays in the cementing operations. At present there is no technology available to monitor cementing operations in real time from the time of placement through the borehole service life. Also, there is no reliable method to determine the length of the competent cement supporting the casing. In this study, smart cement with 0.38 and 0.54 water-tocement ratio (w/c) was modified with iron nanoparticles (NanoFe) to have better sensing properties, so that its behavior can be monitored at various stages of construction and during the service life of wells. A series of experiments evaluated well smart cement behavior with and without NanoFe in order to identify the most reliable sensing properties that can also be relatively easily monitored. Tests were performed on the smart cement from the time of mixing to hardened state behavior. During the initial setting the electrical resistivity changed with time based on the w/c and the amount of NanoFe used to modify smart oil well cement. The shear thinning behavior of the smart cement slurries with and without NanoFe at different w/c ratio and temperatures have been quantified using the hyperbolic model and compared with three material parameters, Vocadlo model. The results showed that the hyperbolic model predicated the shear thinning relationship between the shear stress and shear strain rate of the NanoFe modified smart cement slurries very well. Also the hyperbolic model has a maximum shear stress limit were as the other model did not have a limit on the maximum shear stress. Based on the hyperbolic model the maximum shear stresses with w/c ratio of 0.34 and 0.54 modified with 1% NanoFe at temperature of 25C were 236 Pa and 74 Pa respectively. A new quantification concept has been developed to characterize cement curing based on electrical resistivity changes in the first 24 hours and 7 days of curing. When cement was modified with 0.1% of conductive filer (CF), the piezoresistive behavior of the hardened smart cement was improved without affecting the rheological and setting properties of the cement based on the w/c ratio and the NanoFe content. The test results showed that NanoFe reduced the electrical resistivity of the smart cement slurries. The 1% of NanoFe also affected the rheological properties and the piezoresistive behavior of the smart cement. . The RI24hr for the smart cement with NanoFe decreased with the amount of NanoFe. Addition of 1% NanoFe increased the compressive strength of the smart cement with w/c ratio of 0.38 and 0.54 by 3% and 15% after 1 day of curing respectively. For the smart cement (w/c=0.38) modified with NanoFe, the resistivity change at peak stress was over 2500 times higher than the change in the compressive strain. A linear correlation was obtained between the RI24hr and the compressive strength of the modified smart cement based on the w/c and curing time. Introduction As Deepwater exploration and production of oil and gas expands around the world, there are unique challenges in well construction beginning at the seafloor. Recent case studies on cementing failures have clearly identified several issues that resulted in various types of delays in the cementing operations. Also preventing the loss of fluids to the formations and proper well cementing have become critical issues in well construction to ensure wellbore integrity because of varying down hole conditions (Eoff et al. 2009; Labibzadeh et al. 2010). Moreover, the environmental friendliness of the cements is a critical issue that is becoming increasingly important (Thaemlitz et al. 1999; Dom et al. 2007). Lack of cement returns may compromise the casing support, and excess cement returns can cause problems with flow and control lines (Fuller et al. 2002; Gill et al. 2005). Hence there is a need for monitoring the cementing operation in real time. Free ions in the cement slurry have significant effect on electrical resistivity of samples. According to the literature conductivity of cement is mostly related to the three main parameters which are ion concentration, the number of charges per ion and the equivalent ionic conductivity it should be noted according to current experimental results other parameters that has significant effect on resistivity of cement during hydration are curing temperature, curing condition, weight loss during curing and method of resistivity measurement, two probe of four probe testing and frequency of measurement. AADE-15-NTCE-06 Nanoparticle Modified Smart Oil Well Cement for Monitoring Cementing Applications Cumaraswamy Vipulanandan and Ahmed Mohammed, CIGMATUniversity of Houston 2 C. Vipulanandan and A. Mohammed AADE-15-NTCE-06 Two studies done during the period of 1971 to 1991 and 1992 to 2006 clearly identified cement failures as the major cause for blowouts (McCarter 1996). Cementing failures increased significantly during the second period of study when 18 of the 39 blowouts were due to cementing problem (McCarter 1996). Electrical resistivity measurement has been applied by many researches on concrete and other cementing applications (McCarter 2006), but there are no reports in the literature of electrical resistivity measurements for characterizing oil well cement. Electrical response characteristics measurement has appropriate sensitivity in monitoring the characteristics of cementitious materials (Mc Carter et al. 1991). The advantages in using this technique include its accuracy, ease of testing and procedures, and nondestructive characteristics (Li et al. 2003). Additionally, this method can be used for monitoring the long term behavior of cement in practice. Electrical resistivity of cement is affected by a number of factors, such as pore structure (continuity and tortuosity), pore solution composition, cementitious content, water-to-cement ratio (w/c), moisture content, and temperature (Polder et al. 2001). Moreover, electrical resistivity of cement is dramatically affected by admixtures, due to the resistivity contrast between cement and the admixture substances. Vipulanandan et al. (2006-2014) have studied the change in electrical resistivity with applied stress, referred to as piezoresistive behavior of modified cementitious and polymer composites. Objectives The overall objective of the study was to determine the effect of NanoFe on the behavior of smart oil well cement. The specific objectives are as follows: (i) Investigate the effect of w/c and NanoFe on the rheological and electrical properties of smart oil well cement. (ii) Quantify the effect of NanoFe on the piezoresistive behavior of smart cement. Materials and Methods Smart Cement Commercially available oil well cement (Class H cement) was modified with additives to make it a piezoresistive material. Iron Nanoparticles (NanoFe) Commercially available nano iron was used in this study. Based on the manufacture's data sheet the particle size was 30 nm, bulk density of 0.25 gm/cc and surface area of 38 m/gm. Cement Samples The samples were prepared according to the API standards. Smart cement with a w/c ratio of 0.38 and 0.54 were used in this study. Four series of cement slurries without and with 1% of NanoFe were prepared. After mixing, specimens were prepared using cylindrical molds with a diameter of 2 inches and a height of 4 inches. Two conductive wires were placed in all of the molds which were 5 cm apart. All specimens were capped to minimize moisture loss and were cured up to the 28 days for the piezoresistivity test under compressive loading. Rheological Tests Rheological properties determine the ability of cement to be pumped. The rheology tests were performed by utilizing a rotational viscometer at room pressure and temperature at rpms ranging from 3 to 600 rpm, and related shear stresses were recorded. The viscometers were calibrated using several standard solutions. Electrical Resistivity Two different instruments were used to measure the electrical resistivity of the smart cement. (i) Conductivity Probe Commercially available conductivity probe was used to measure the conductivity (inverse of electrical resistivity) of the fluids. In the case of cement, this meter was used during the initial curing of the cement. The conductivity measuring range was from 0.1μS/cm to 1000 mS/cm representing a resistivity of 10,000 Ω.m to 0.1 Ω.m. (ii) Digital Resistivity Meter Digital resistivity meter measured the resistivity of fluids, slurries and semi-solids with resistivity in the range of 0.01 Ω-m to 400 Ω-m. Both of the electrical resistivity devices were calibrated using standard solution. Based on past studies, electrical resistivity was selected the monitoring parameter to quantify the performance of modified cement during curing and hardening process (Vipulanandan et al. 2014 (a) and (b)). Further, Electrical resistance was measured using LCR meter during the curing time. To minimize the contact resistances, the resistance was measured at 300 kHz using two-wire method. Each specimen was calibrated to obtain the electrical resistivity (ρ) from the measured electrical resistance (R) based on the Eqn.1.


The post-GFC era sees slower global growth, unusually combined with lower investment financing costs, a substantial Chinese slowdown and with the eventual prospect of a US-led re-tightening of global financial markets. For Indonesia in the medium term, these developments imply a slowing of export growth and a temporary surge in net inward investment incentives. These changes are examined here using a numerical macro model. The results suggest that recent fiscal reform is long run beneficial and that it will moderate the negative effects of expectations linked to the eventual financial tightening. Indeed, results depend importantly on whether expectations are formed on the short run effects or the prospective tightening. Expectations retard growth in either case. Depending on magnitudes, the prospect of financial tightening may be preferable to nearer term financial easing that is combined with comparatively unattractive export moderation.


This paper empirically examines the determinants of credit at different maturities across European Union countries during the last decade. The paper documents the lengthening of maturities since the early 2000s, and whether these patterns were driven by similar factors in advanced countries and in emerging market countries. Before the 2008 crisis, long-term credit expanded faster than short-term credit in most countries in the sample, and contracted less than short-term credit after 2008. The paper finds that domestic deposits and foreign liabilities were more important sources of funding in emerging market countries than in advanced countries. Moreover, trade openness and initial banking sector depth matter more for emerging market countries than for advanced countries.


Relevant domains of cooperation between Guangdong and Hainan can be found,be it considered as to their historical origin,geological location,or their economic and social development. In terms of urbanization,Guangdong has,after thirty-odd years' exploration and accumulation since economic reform and opening-up in1978,formulated its own model with its own characteristics,whose many measures and ideas Hainan can refer to.In view of this,it is of practical significance to pursue an urbanization model tailored to conditions of Hainan through a comparison and analysis of the current development of urbanization in Guangdong and Hainan and in combination with the characteristics of urbanization of the Pearl River Delta.


This study was conducted to examine primiparas' perception of delivery experience and identity as the mother("Myself as the Mother" and "My Baby") according to delivery methods such as normal delivery and cesarean section.The result of this study summarized as follows.1. The primiparas' perception of delivery experience according to delivery methods showed that the primipars who had normally delivered perceives the delivery experience more positively than those by cesarean section(t=4.88, p=0.000). This fact supported hypothesis 1 that "the primiparas group by normal delivery should perceive the delivery experience more positively that by cesarean section." 2. The primiparas who had delivered by cesarean section were more positive in the SD-Self score than those who had normally delivered at the time when four weeks passed after delivered, and there was a significant difference(t=-4.21, p.000). Therefore, hypothesis 2-1 that "the primiparas group who had normally delivered should be more positive in the SD-Self 1-2 days and 4 weeks after delivery than one who delivered by cesarean section" was rejected.3. It was shown that the primiparas who had delivered normally were more positive in the SD-Baby 1-2 days 4 weeks after delivery than those who delivered by cesarean section(after-delivery 1-2 days : t=3.10, p=0.002 and after-delivery 4 weeks : t=2.15, p=0.034). Based on this fact, hypothesis 2-2 that "the primiparas group who had delivered normally should be more positive in the SD-Baby 1-2days and 4 weeks after delivery than those who had delivered by cesarean section"was supported.4. Primiparas who had delivered by cesarean section appeared to have a positive identity as the mother by showing a more significant difference (t=7.96, p=0.000) 4 weeks after delivery than 1-2 days after delivery.In conclusion, we see that primiparas' perception of delivery experience and identity as the mother were different according to delivery methods. Thus, it is required to devise a nursing in tervention strategy to expand support from the health care system and opportunities to provide pre. post-delivery programs so that primiparas can have a positive perception of delivery experience and a positive identity as the mother.Based on conclusion stated above, the following suggestions are made.1. As this study compared the perception of delivery experience and identity as the mother between prmiparas who had delivered normally and ones who had delivered by cesarean section, the further study on comparison between multiparas who had delivered normally and ones who had delivered by cesarean section is needed.2. According to the results of this study, longitudinal study is needed to examine the difference and change in the formation of maternal identity.3. According to the result of this study, a study is also needed to determine interaction between time for maternal identity and delivery methods.


Though a plethora of varied probes, thus far, have been conducted into the effectiveness of emotional intelligence as well as the paramountcy of self-efficacy in educational settings, one area of research that seems to have remained partly intact or which has been given scant attention is the viable relationship between these two constructs, i.e. EQ and self-efficacy. In effect, the principal incentive underlying the researchers' interest in the current study emanated from their credence in the fact that meager heed has been given to the possible links holding between these two realm, particularly when it comes to considering the case of academic professors; indeed, the few number of studies being carried out in this respect have merely centered on the lower-level teachers among which a reference can be made to Chan (2004) and Fabio and Palazzeschi (2008). Hence, in view of the aforesaid facts, the researchers in the current study aimed at addressing the correlation between EI and self-efficacy in a brand new context (academic arena) and with a totally unique community (university professors). Age and teaching experience of professors were also the issues of secondary concern in performing the present research. To this end, 50 EFL university professors (both MA and PhD holders) were selected from a range of different universities in Urmia, including the English departments of Urmia state and Azad universities, Azarabadegan non-profit University, as well as Payam-e-Nour University. To gather the data, Tschannen-Moran and Woolfolk Hoy's (2001) self-efficacy scale and Bar-On's (1997) EQ-i questionnaire were administered to the participants. The final analysis of data revealed a significant correlation between the participants' responses to these two questionnaires. Yet, the participants' ages and years of teaching experience were not found to be of significant role with respect to the relationship between the participants' performance on the said scales.


Chinese women live in the complicate background of the era and area: a civilization of long standing in the East Asian region, and also the radical changes in China in terms of rapid industrialization, informatization and globalization. Women surveys show their state of life and their demand for libraries: lower economic and social status and more conservative living style than of men, lower educational level and larger information gap than average in society. What they need most is assistance in acquiring information, such as legal aid, and reading opportunities provided in libraries. A public library in China - Nanshan Library of Shenzhen City is taken as an example to share the practical experience of four service projects: "Spring Program", counselling to aid the spiritual growth of women and their children; "Sunshine Program" offers legal aid; health lectures urge women to take care of their bodies; reading salons encourage women to read books for themselves and read books with their children. There are also further plans for services for women in the library: to provide information technology training and the space for cultural entertainment; to launch career development and guidance for unemployed women; and special services for anti-domestic violence.


Purpose – The efficiency and effectiveness of reverse logistics (RL) is dependent on collection methods as the collection activities are critical in determining the economic viability of the entire recovery chain. The purpose of this paper is to evaluate the various collection methods used in RL under uncertain environment. Design/methodology/approach – An integrated fuzzy multi-criteria decision model has been developed for the evaluation of various collection methods. The evaluation has been done based on the criteria of initial investment, value added recovery, return volume, operating cost, degree of supply chain control, and level of customer satisfaction. The three alternatives used in the study are collection by the manufacturer directly from the customer, collection by the retailer, and collection by the third party. The fuzzy analytical hierarchy process has been used to compute the criteria weights and fuzzy technique for order preference by similarity to ideal solution has been used to rank the...


A WiMedia compliant CMOS RF power amplifler (PA) for ultra-wideband (UWB) transmitter in the 3.1 to 4.8GHz band is presented in this paper. The proposed two-stage PA employs a cascode topology on the flrst stage as driver while the second stage is a simple common source (CS) amplifler. In order to improve the e-ciency and output power, the output impedance of the driver amplifler (flrst stage) is optimized so that it falls on the source-pull contours of the second stage amplifler. On-wafer measurement on the fabricated prototype showed a maximum power gain of +15:8dB, 0.6dB gain ∞atness, +11:3dBm of output 1dB gain compression and up to a maximum of 17.3% power added e-ciency (PAE) at 4GHz using a 50› load termination, while consuming only 25.7mW from a 1.8V supply voltage. Measurement results obtained are used to create a non-linear power-dependent S-parameter (P2D) model for wideband input and output matching optimizations and co-simulations with the UWB modulated test signals. Using the created P2D model, the PA achieved a maximum output channel power of +3:48dBm with an error vector magnitude (EVM) of i23:1dB and complied with the WiMedia mask speciflcations.


Large seeds are thought to provide an adaptive advantage to seedlings growing in shaded environments. Four hypotheses that could account for the possible mechanisms underlying this advantage were tested using 23 species ranging in seed size from 0.04 to 22.2 mg. The hypotheses were: seedlings from large seeds are able to survive longer in shade than seedlings from small seeds; seedlings from large seeds divert relatively more resources to shoot development when grown under shaded conditions compared to seedlings from small seeds; seedlings from large seeds always have larger shoots than small-seeded seedlings growing under shaded conditions due to the large initial reserve size of large seeds and the reduction in growth rate differences between small and large seeds under growth-limiting conditions (...)
