Arriving in Brisbane some six years ago, I could not help being impressed by what may be prosaically described as its atmospheric amenity resources. Perhaps this in part was due to
 my recent experiences in major urban centres in North America, but since that time, that sparkling quality and the blue skies seem to have progressively diminished. Unfortunately, there is also
 objective evidence available to suggest that this apparent deterioration is not merely the result of habituation of the senses. Air pollution data for the city show trends of increasing
 concentrations of those very substances that have destroyed the attractiveness of major population centres elsewhere, with climates initially as salubrious. Indeed, present figures indicate that
 photochemical smog in unacceptably high concentrations is rapidly becoming endemic also over Brisbane. These regrettable developments should come as no surprise. The society at large has not been
 inclined to respond purposefully to warnings of impending environmental problems, despite the experiences and publicity from overseas and even from other cities within Australia. Nor, up to the
 present, have certain politicians and government officials displayed stances beyond those necessary for the maintenance of a decorum of concern. At this stage, there still exists the possibility
 for meaningful government action without the embarrassment of losing political favour with the electorate. To the contrary, there is every chance that such action may be turned to advantage with
 increased public enlightenment. It would be more than a pity to miss perhaps the final remaining opportunity: Queensland is one of the few remaining places in the world with sufficient resources to
 permit both rational development and high environmental quality. The choice appears to be one of making a relatively minor investment now for a large financial and social gain the near future, or,
 permitting Brisbane to degenerate gradually into just another stagnated Los Angeles or Sydney. The present monograph attempts to introduce the problem by reviewing the available research on air
 quality in the Brisbane area. It also tries to elucidate some seemingly obvious, but so far unapplied management approaches. By necessity, such a broad treatment needs to make inroads into
 extensive ranges of subject areas, including political and legal practices to public perceptions, scientific measurement and statistical analysis to dynamics of air flow. Clearly, it does not
 pretend to be definitive in any of these fields, but it does try to emphasize those adjustable facets of the human use system of natural resources, too often neglected in favour of air pollution
 control technology. The crossing of disciplinary boundaries, however, needs no apology: air quality problems are ubiquitous, touching upon space, time and human interaction.


Mid-infrared laser wavelengths offer advantages as a source for coronary angioplasty based upon the excellent fiberoptic transmission and the enhanced tissue absorption of these photons. We report the results of a pilot clinical trial of a Holmium:YAG (2.1 micrometers ) coronary laser angioplasty using a prototype (1.6 mm and 2.0 mm) multifiber catheters. Coronary laser angioplasty with or without adjunctive balloon angioplasty or directional atherectomy was performed in 14 patients with 17 coronary stenoses. Laser success was obtained in 13/14 (93%) patients and 16/17 (94%) lesions. Uncomplicated procedural success was achieved in 9/14 (64%) patients and 12/17 (71%) lesions. Our initial laser success rate was very encouraging using this prototype multifiber catheter with a holmium:YAG laser. However, our overall procedural success rate was disappointing, and not superior to that expected with conventional angioplasty alone. The holmium laser remains an attractive energy source for laser angioplasty, but its utility is limited by catheters which create inadequate channels for stand-alone laser angioplasty.


Three resistance type humidity sensors (polyethyl-enimine, polyethyl-ammonium salt and PEO) were studied at various temperatures and humidities by  ̄1H NMR. The hu miditive sensibility mechanism of these sensors was proposed through the change of chemical shifts. The active hydrogen in the three materials reacts with H_2O to form new active hydro gen, and the exchange interaction of new active hydrogen with old ones is very fast. At the same time, the current carriers are generated. As a result , the resistance of materials is de creased with raising humidity.


When our shadow falls on fog or clouds, a coloured system of rings of a few degrees in diameter appears centred at the shadow point of our eyes. If we are close enough to the fog bank we also may discern our own shadow, which is then crowned with an aureole similar to those on religious paintings from the Middle Ages. So the phenomenon, not without reason, is called 'glory'. In the past, the glory was seldom observed as very few people were in a position to watch clouds from above. The scarce pre1960 photographs of a glory were usually taken from mountains, mostly showing a glory with its lower segment missing because of the shadow of the mountain (Figure 1). As that problem does not occur on an aircraft, the glory appears with full 360° coloured rings. Such a complete glory is a common companion of air travellers nowadays, often mistakenly described as 'a little rainbow following the aircraft'. If one's aircraft is sufficiently high above the clouds to make its shadow invisible, one can even observe the glory ́s central point (Figure 2). A glory is formed when light is backscattered by spherical droplets. If a light path exists through a spherical body (other than a simple back reflection) which enables backscattering, then a bright region appears around the shadow point surrounded by coloured interference rings. As the refractive index of water is too low to achieve such backscattering with normal light rays, a satisfactory explanation of the glory was not given until 1947 when the role of surface waves was recognized (Van de Hulst, 1947). As surface waves are effective only in small drops, a glory appears in cloud or fog, but never in rain.


This study is a study of the problems with images shown in soju advertisements. In particular, when looking at the poster of advertisements for soju among alcoholic beverages, most of them are female models to target male consumers. The purpose of this study is to examine the case analysis of the female image shown in the soju advertisement posters and to identify problems in images through surveys of male consumers, the main consumers of soju, and to explore effective soju advertising directions. As a result of the analysis, it identified 'uniformity of advertisement image type' and 'The female image is unified' which are the problems of soju advertisement image. And 48 percent of male consumers think negative about this situation. In addition, by using excessive pop stars, the relationship between the model and the product is less, which leads to a problem of low advertising reliability. This study can be helpful for the ethical and moral correct development of advertising targeting male consumers as well as mainstream advertising.

The development of cost‐effective and high‐performance electrocatalysts for oxygen evolution reaction (OER) is essential for sustainable energy storage and conversion processes. This study reports a novel and facile approach to the hierarchical‐structured sheet‐on‐sheet sandwich‐like nanocomposite of CoNiO x /reduced graphene oxide as highly active electrocatalysts for water oxidation. Notably, the as‐prepared composite can operate smoothly both in 0.1 and 1.0 m KOH alkaline media, displaying extremely low overpotentials, fast kinetics, and strong durability over long‐term continuous electrolysis. Impressively, it is found that its catalytic activity can be further promoted by anodic conditioning owing to the in situ generation of electrocatalytic active species (i.e., metal hydroxide/(oxy)hydroxides) and the enriched oxygen deficiencies at the surface. The achieved ultrahigh performance is unmatched by most of the transition‐metal/nonmetal‐based catalysts reported so far, and even better than the state‐of‐the‐art noble‐metal catalysts, which can be attributed to its special well‐defined physicochemical textural features including hierarchical architecture, large surface area, porous thin nanosheets constructed from CoNiO x nanoparticles (≈5 nm in size), and the incorporation of charge‐conducting graphene. This work provides a promising strategy to develop earth‐abundant advanced OER electrocatalysts to replace noble metals for a multitude of renewable energy technologies.


This study documents the diversity and distribution patterns of dung beetles in three relictual patches of montane forest located near the Sabana de Bogota. 2486 individuals of 11 species in 6 genera were collected. The most abundant specie was Ontherus brevicollis, collected in two patches, followed by Dichotomius achamas collected in all three patches and Uroxys sp present only in one. Chicaque has the highest species richness with 10 species. We found a clear pattern related to habitat preferences, summarized in 3 groups: pasture beetles, edges and forest interior beetles.


A model for protogalactic star-forming regions is presented that assumes that self-gravitating isothermal clouds form by gravitational instability of cooling, shocked gas layers in the protogalaxy. This pregalactic environment is ideal for a dynamo mechanism to be operative. The dynamo requires a seed field whose origin is described. The results are applied to the problem of protogalactic star formation. The implications of the model for observations of protogalaxies and protogalactic magnetic fields are described. 60 refs.


In this thesis, it is argued that Jungian and post-Jungian perspectives, in contrast to Freudian and Adlerian, have been neglected in classic and contemporary career development theories. This omission is addressed by undertaking a critical evaluation of career development theory in relation to analytical psychology. The primary research strategy adopted is a systematic and critical comparison of the two literatures. Canonical and contemporary texts from within career studies are selected focusing on seven areas of career theory: cultural systems; personality; career types; career strategies; narrative; life course development; and learning. These are critically evaluated using concepts from analytical psychology. Specifically, the work of Jung and post-Jungian scholars is deployed in relation to individuation and the key themes of: projection; persona; typology; archetypal image; personal myth; vocation; and transformational learning. The original contribution is a post-Jungian evaluation and re-imagination of career development theory. It is suggested that cultural career theory can be enhanced by considering the role of projection. In addition, it is argued that self-concept career theory is enriched by Jung's structural model of the psyche; and the literature on career types can be broadened to include typology. It is further proposed that individuation offers a more critical take on career strategies; and personal myth extends the narrative turn in career studies. Finally, it is claimed that developmental theory is illuminated by an analytical psychological view of vocation; and career learning augmented by transformational learning theory. Overall, it is argued that career means to carry life, and through personal myth, weave together the golden threads that connect us all.


The invention provides a manufacturing method of a small-inner-diameter hollow spindle, which comprises the following steps: dividing a small-inner-diameter spindle into a plurality of spindle sections, respectively carrying out sectional forging, welding into an integral body, and carrying out stress-relief annealing on the small-inner-diameter spindle to finish the outer circle and the inner circle, thereby obtaining the finished product. The inner side of the welding joint of every two adjacent spindle sections is an assembly seam/spigot, and the outer side is a welding seam bevel. The welding process comprises the following two steps: carrying out bottoming and root welding in an argon arc welding mode, and filling and capping in a submerged arc welding mode. The invention implements sectional processing of the small-inner-diameter hollow spindle of a hydroelectric generating set, thereby greatly lowering the manufacturing cost, shortening the production cycle of the small-inner-diameter spindle, ensuring the welding quality of the small-inner-diameter spindle and relieving the manufacturing bottleneck of the small-inner-diameter spindle.


This work develops a method in which chemical tracers in the drilling fluid help determine mud filtrate invasion and the degree of oil flushing during coring of steamed and unsteamed heavy-oil formations. Salts of iodide and bromide were added to the drilling fluid while Well TO3 was cored through the Lombardi and Aurignac zones at San Ardo field in California. Vertical core plugs, taken from the periphery to the center of the retrieved whole core, were analyzed for tracer concentration. Tracer analyses indicated minimal filtrate invasion in the not-yet-steamflooded Lombardi zone and complete filtrate invasion in the steamflooded Aurignac zone. Tracer and oil saturation analyses showed the Lombardi zone to be uniform from top to bottom with an average oil saturation of 42.5% and an average porosity of 31.1%. Interpretation of tracer and oil saturation data permitted the construction of a layered model for the Aurignac zone. The layers ranged from an average oil saturation of 8% in the steamflooded layer to 37% in the bottom layer. The data showed that significant oil flushing (6%) occurred only in cores taken from the hot-waterflooded layer just below the steam zone. Vertical core-plug porosities and saturations, as determined by a unique calculatingmore » scheme, were compared with conventional and Elkins-corrected values. The comparison indicated that misapplication of the Elkins method in high-temperature formations may result in significant errors.« less


Purpose – The purpose of this paper is to explore the experiences and opinions of mental health professionals working in two rehabilitation wards to a clinical dashboard system. Design/methodology/approach – Following the creation of the clinical dashboards, a questionnaire was developed and sent to staff and patients across two clinical wards involved in the clinical dashboard mental health pilot. Findings – The clinical dashboards were viewed as being useful tools for clinicians, supporting engagement.

Research limitations/implications – The main limitations included the sample size, responder bias and the limited sampling period. It would have been helpful to have obtained further responses to understand why individuals came to their conc...


Twenty‐three clinically silent prostatic carcinomas discovered in Japanese men at autopsy were surveyed for ras proto‐oncogene mutations by mutation‐specific oligonucleotide probe hybridization after polymerase chain reaction (PCR) amplification from a section of formalin‐fixed, paraffin‐embedded tissue. Six of the 22 that were satisfactorily amplified contained activating point mutations in codon 12 of K‐ras, a significantly higher frequency than has been reported in patients with clinically advanced disease in the United States. Of the six cases with activating point mutations in codon 12 of K‐ras, one had a GGT → GAT transition, four had GGT → GTT trans‐versions, and one had both GGT → GAT and GGT → GTT mutations. Sections from the same tissues were immunohistochemically stained with an anti‐ras p21 antibody. Carcinoma cells stained for ras p21 to some degree in 13 cases. Immunohistochemically detectable expression of p21 was always focal and was not necessarily associated with K‐ras mutation. K‐ras oncogene activation in prostatic carcinoma appears to merit additional study as a significant event in the pathogenesis of this neoplasm.


The incremental problem for a class Q of graph queries aims to compute, given a query Q in 'Q, graph G, output Q(G) and updates Δ G to G as input, changes Δ O to Q(G) such that Q(G ⊕ Δ G) = Q(G) ⊕ Δ O. It is called bounded if its cost can be expressed as a polynomial function in the sizes of Q, Δ G and Δ O. It is to reduce computations on possibly big G to small Δ G and Δ O. No matter how desirable, however, our first results are negative: for common graph queries such as graph traversal, connectivity, keyword search and pattern matching, their incremental problems are unbounded. In light of the negative results, we propose two characterizations for the effectiveness of incremental computation: (a) localizable, if its cost is decided by small neighbors of nodes in Δ G instead of the entire G; and (b) bounded relative to a batch algorithm T, if the cost is determined by the sizes of Δ G and changes to the affected area that is necessarily checked by T. We show that the incremental computations above are either localizable or relatively bounded, by providing corresponding incremental algorithms. That is, we can either reduce the incremental computations on big graphs to small data, or incrementalize batch algorithms by minimizing unnecessary recomputation. Using real-life graphs, we experimentally verify the effectiveness of our algorithms.


AT a time when so much painting is in the non-objective vein, it seems relevant to investigate the aesthetic theories of the artist who was the first champion of non-objective art, or "concrete art,"1 as he preferred to call it. It is possible that non-objective paintings may have been painted prior to Kandinsky's first non-objective watercolor (Fig. I) of 1910 and his more ambitious Impressions, Improvisations, and Compositions of 1911. There are abstractions by Arthur Dove, for example, which are dated 1910. Picabia and Kupka began working in a non-objective idiom not much later,2 and Delaunay painted his non-objective Color Disks in 1912.3 In Germany Adolf Hoelzel ventured into non-objective painting as early as 1910, but whereas for Hoelzel it was merely experiment in additional possibilities, Kandinsky made non-objectivity the very foundation of his pictorial imagery.4


Film scholar Mark Browning offers the first detailed analysis of the work of David Fincher, director of the critically acclaimed films Seven, Fight Club, and The Curious Case of Benjamin Button.
 David Fincher is one of the most exciting filmmakers working in Hollywood today. He has produced a string of groundbreaking films that have achieved both critical and commercial success, while constantly challenging audiences to rethink their expectations of generic boundaries. David Fincher: Films That Scar is the first truly analytical work on the films of this mysterious and complex filmmaker.
 This insightful book analyzes all of Fincher's feature films, as well as examples of his commercials and pop videos, tracing key influences that include his background in special effects. It considers how he creates roles for strong women, how he has extended the detective genre, and how he adapts cult texts. The book also questions whether Fincher's films, famous for their downbeat endings and "dark" visual style, are really bleak or just part of an unconventional approach to filmmaking. In the end, readers will understand the development of Fincher's individual films and appreciate how the films relate closely to each other.

This paper tries to give a clear summary of the various fields that can contribute, intentionally or not, to the IGRF Gauss coefficients at present, leading to some ambiguities. It points out how modellers have developed various practices without any explicit external notification, and argues that it would be logical and useful if we could agree how best to tackle some of the problems that have arisen, and to convey our solution as simply as possible to the user community. It suggests a simple wording for a possible future definition of the IGRF.


Furnace is an equipment used to heat or change shape. Process control has become increasingly important in industry, as a consequence of global competition, Year after year, furnaces have improved in both process and industrial equipment. The tuning process ensures that system performance meets operating objectives. Artificial Intelligent (AI)-based intelligent control has developed a lot to improve conventional controls to control voltage loads and is always under constant assessment of the variable. In this research task, it will be discussed about the control of the furnace temperature so that it remains constant with PID and by tuning the Firefly Algorithm (FA) with changes in the output voltage obtained which have better settling time, overshoot and undershoot.


This article focuses on the role of departmental culture and academic climate in shaping the experiences of master's and doctoral students in geography. Structured logging of experiences at nine geography graduate programs over six months reveals the types of support provided to graduate students; how students cope with emotional, academic, and financial challenges; and ways students become integrated (or not) in department communities. Analysis of log data considers variation by subgroups (gender, citizenship, program type, full- or part-time status, race, and ethnicity). For all students, the findings indicate the importance of unplanned, spontaneous, and other informal events, as well as relationships of a more formal nature with advisors and faculty in the department and beyond. Students also noted the importance of having access to resources, professional development opportunities, and support from peers as factors affecting their sense of progress and belonging in a department community.


Medical schools in the northeast of the United States are least likely to produce graduates who end up working in primary care, a new analysis shows. Graduates from these schools are also least likely to end up in areas that are underserved by doctors and to come from an ethnic minority, it found.

The study, which aimed to score all US medical schools on their ability to meet a "social mission," found that "historically black" schools performed the best and that public schools performed better than private ones ( Annals of Internal Medicine 2010;152:804-11). "Historically black" institutions are those that were established before 1964 with the intention of serving …


Transportation mobility in the city of Dumai which is increasingly increasing requires the provision of pedestrian facilities such as pedestrian bridges. However, the existing Crossing Bridge is not used optimally because of the condition of the bridge precisely on the bridge floor which has been damaged so that it can endanger the crossers who will use it.

 THE TASK FORCE ON ENGLISH EDUCATION
 ABSTRACT
 ln 1991 the Quebec Minister of Education established a Task Force to inquire into several matters affecting the English-language school system, including severely declining enrolments. The Task Force has recommended changes to the law concerning accessibility to English schooling, to the organization of the Ministry of Education, to school board structures, and to the curriculum. It remains to be seen which of these recommendations will be implemented.

Le groupe de travail a recommande que des modifications soient apportees a la loi en ce qui a trait a l'acces a l'ecole anglaise, a l'organisation du ministere de l'Education, a la structure des commissions scolaires et aux programmes d'etudes. Il reste a voir si ces recommandations seront suivies d'effets.


The microporous metal-organic framework Ni(2)(dhtp) (H(4)dhtp=2,5-dihydroxyterephthalic acid) shows distinct end-on CO(2) coordination to coordinatively unsaturated nickel sites giving rise to high CO(2) adsorption capacity at sub-atmospheric pressures and ambient temperatures.


The present invention provides an electrochemical biosensor, a method for producing the same, and a method for manufacturing an electrode layer. The method for manufacturing the electrochemical biosensor comprises the following steps of forming a plurality of phase intervals on an insulating substrate and the penetrating holes penetrating the substrate respectively; at least forming an active metal layer in each penetrating hole of the substrate; forming an electrode layer made of a metal material on the active metal layer; forming the electrochemical reaction layers electrically connected with the electrode layers on the upper surface of the substrate; and covering the covering members on the electrochemical reaction layers respectively. By utilizing the active metal layers to combine the electrode layers in the penetrating holes of the substrate, a simpler process and a better jointing degree of the electrodes and the substrate can be provided, and the metal electrode raw material cost can be reduced.


We present ab initio quantum‐chemical calculations including correlation effects via second‐order Mo/ller–Plesset perturbation theory, of the structures of the complexes that benzene forms with water, ammonia, methane, and formic acid, and of the pyrene–water complex. We describe our results for a number of complex structures, including symmetric and nonsymmetric configurations, in which the aromatic molecule acts as proton acceptor. In some instances, configurations where benzene is the proton donor are also investigated. Series of calculations are performed in order to assess the energy required for the Lewis acid molecule to move on top of benzene or pyrene. Our results are compared to available experimental data on the geometries and relative binding energies of these complexes.


Soil compaction resulted from heavy machineries in opencast coal mine areas alters soil macropore characteristics then affects soil hydraulic properties. Additional information related to hydraulic characteristics is needed to assess the effects of soil reconstruction to improve the soil quality. The aim of this study was to determine the hydraulic properties and macropore characteristics of compacted soil by simulation tests and CT scanning in laboratory and to explore the response of soil hydraulic properties to soil macropore characteristics. In this study, the disturbed soil samples from the dumping area of Pingshuo opencast coal mine of China were collected. The soil samples were processed in designed bulk density (BD) from 1.30 g·cm-3 to 1.70 g·cm-3, and the soil hydraulic properties, including soil-water characteristic curve (SWCC), saturated hydraulic conductivity ( Ks), soil moisture diffusivity (D(θ) ), field capacity (FC), wilting coefficient (WC) were measured and the soil macropore characteristics were obtained using CT scanning in laboratory. The path analysis method was applied to analyze the effect of macropore characteristics on soil hydraulic properties. Soil compaction resulted in severe effects on soil hydraulic characteristics and macropore properties. Under same soil suction, the water contents remained in soil decreased with increasing compaction. Soil-water holding capacity, soil saturated hydraulic conductivity, and soil water diffusivity decreased with increasing BD. The explanatory variables (average euler number (AEN), macropore throat number (PTN), and macropore fractal dimension (PFD)) were main determinants of soil-water holding capacity, and the indirect path coefficient of macroporosity. The effects of average euler number (AEN) and macropore fractal dimension (PFD) on soil infiltration properties were relatively high. The BD of 1.4 g·cm-3 was a critical point of affecting macropore properties then affecting soil hydraulic properties, and some soil reclamation measures should be conducted to make BD <1.4 g·cm-3 for compacted soil in opencast coal mining area. This study provides valuable data for soil restoration of soil hydraulic and macropore properties in mining areas.

A flexibility‐based component mode synthesis (CMS) is proposed for reduced‐order modelling of dynamic behaviour of large structures. The approach employs partitioning via the localized Lagrange multiplier method. The use of the localized Lagrange multipliers leads to, unlike the classical Lagrange multipliers, a linearly independent set of interface forces without any redundancies at multiply connected interface nodes. The flexibility‐based CMS method has shown significant advantages over the classical Craig–Bampton method. A key feature of the method is its substructural mode selection criterion that is independent of loading conditions. Unlike the majority of available CMS approaches, where one retains the full dimension of partition boundary degrees of freedom (DOFs), the flexibility‐based method allows to reduce significantly the interface DOFs. The reduction of interface DOFs represents the major contribution of the present communication. The efficiency of the proposed approach is demonstrated on an analysis of a simple plate partitioned and of a more complex 3D structure, both partitioned into several substructures.

In this article, we examine the foreign policy implications of different types of investment flows. North–South investment is more sensitive to political risks (expropriation, default, civil war) than North–North investment. We argue that North–South investment flows create a constituency within the US financial sector that is likely to support stabilising intervention – military intervention aimed at reducing political risk abroad. Examining political action committee donations from Fortune 500 financial firms with a cross-sectional Tobit model, we find that US financial firms with greater exposure to the Global South are likely to favour congressional candidates with a record of voting for intervention in developing countries. This study contributes to the literature on economic interdependence and peace, proposes an original method for capturing the revealed preferences of political actors, and enhances our understanding of the sectoral underpinnings of foreign policy-making.


The geographical proximity and cultural homology make the cross-border peoples of China and Vietnam have common ground in many areas such as religion, beliefs, and living customs. A comparative study is made of the culture of Song Genius derived from the legend of Third sister liu, which is widely circulated in the Lingnan region of China, and the Song Genius culture, which has evolved from the beliefs of neighboring Vietnam's mother road, expounds the origin, connection, connotation, and future development trends between the two. Then it explains the value of the two in production and life, and further enhances the important position of the Song Genius culture in the cultural exchanges between China and Vietnam and the need to strengthen the unity and integration of the friendly nations.

A hydraulic mechanism of the mechanical-hydraulic mixing device can change the ocean wave energy to the transcending fly wheel kinetic energy, and the mechanical-hydraulic mixing device has the advantages of good antivibration performance and simple and convenient installation, use and maintenance.


Initially defined as being the prerogative of the technician, the act of expertise tends to go towards more democracy and opening with the other stakeholders of the civil society. This tendency is consolidated by the various laws and conventions like the Aarhus convention (1998). Considering the industrial risks management and prevention framework, this tendency is not only the result of a pure ethical conviction "of equity between the stakeholders of the civil society", but reflect the set of changes and transformations undergone and created by the society. Consequently, it is necessary to consider that risk definition, initially specified by the technician, cannot be defined through the only dimensions (probability, intensity and kinetics) but must reconsider some qualitative aspects like considerations around uncertainties, controllability, equity, implication, confidence, values, etc. This conceptual change will have an impact on the way decisions have to be made in risk management processes. But: How to integrate the "process of sharing point of view between stakeholders" in technological risk prevention processes? Is the level of risk acceptability under the pure responsibility of the legislator and/or the technical expert? This paper is an introduction to the societal management of industrial risks. These transformations, combined with an industrial accidental reality increasingly present, cannot be apprehended without considering the differences between the society and one of its important actors: the industry. The answers to these questions are brought through a prism of multi-field reading including: management sciences, social sciences, decision sciences, geography and economical sciences. In this paper we propose an introduction to the corpus of concepts and steps essential to the understanding of " the relation between risks and society". 2 INDUSTRY AND SOCIETY: WHICH RELATION? The term "society" has a dual definition and is a concept used to indicate various things: (i) an organized community of individuals of which life, as autonomous entity, cannot be reduced to the individuals who make it up (Devigne, 1948); (ii) a mode of group of individuals existence having a language, a culture and a civilization in common (Cooley, 1967). For the technician, the society is often regarded as a nebula. A not structured nebula of individuals, which is difficult to apprehend the opinion and the preferences safe through tendencies and having the variability of the nature that the technician allots to this nebula. Seen from the angle of the mass of individuals not structured nor organized, the society is confused with the concept of public; "the public" which it is composed by. In addition to being seen from the angle of "an organization and people who make it up", the society in general, and the civil society in particular, is attached to a geographical space. One will speak then about communal, regional, or even European territory. The individuals act, inside this space, within associative frameworks representing the individual wills and respecting a legal formalism that allow the protection of personal interests. Thus, the society would be at the same time organized and not organized! Herbert Simon already announced it in 1943 (in Demailly and Le Moigne, 1986): "the social organizations are not given, they are designed". But then: What is the difference between "the society" and "industry" from an organizational point of view? 2.1 A question of culture The culture is "a rich developed and deep rooted system of values and beliefs which distinguishes a specific organization from all the others" (Mintzberg, 1989). It is in these terms that Mintzberg represent the set of the beliefs, customs and postulates inherited of past common experiments shared by a group of individuals. Within an industrial organization, this culture is strongly marked with technical knowledge. Thus, chemists, physicists, engineers and technicians in general, share the same interest for analytical or numerical approaches and quantifiable evaluations that are considered to be more precise for the practice of their role in the decision-making process. Formulas, figures and measurements are then set up like common language and mode of representation of industrial reality. The illusion of control is another of the common beliefs of the technicians. But what happen to the same technician, released to its role within industry, when he is a lambda individual in the society: Does he use the same technical language? Does he act according to this same analytical mode?


Phase equilibria relations in the YO1.5–BaO–CuO system at 900°C in air were investigated and the phase diagram of the subsystem YBa2Cu3O7–BaCuO2–CuO was determined by differential thermal analyses, quenching experiments, and X-ray diffraction measurements. Single crystals were grown by the slow cooling method and then characterized.

This article describes the developed and tested flexible bellow, which can det ermine whether the MR fluid is under influence of sedimentation and whether it can opera te correctly or it is necessary to perform the mixing.


Abstract To make a dynamic analysis of ecological capacity and a quantitative analysis of ecological compensation, to promote the sustainable development in a nature reserve, and to make Po‐yang Lake Nature Reserve as an example, the authors obtained information on land‐use change in the years 1985, 1995, 2005 in Po‐yang Lake Nature Reserve based on RS and GIS. Ecological capacity was quantified and its development change, spatial characteristics, and the sustainable development status of the nature reserve with ecological deficits and surpluses were analysed. Results show that land use had been stable since the Po‐yang Lake Nature Reserve came into existence. The change compared grassland (increased 15.22%), water body (increased 7.05%) and unused land (decreased 18.19%). The ecological capacity improved from 1985 to 2005 (the per capita ecological capacity from 0.8284 ha to 1.0534 ha). among nine villages and towns in the reserve, the ecological surplus villages and towns were Wucheng, Tiehe and Changyi, the ecological balance villages and towns deficit were Sanjiao and Shahu. The remainder were in ecological deficit. In all of the nature reserve, the ecological capacity in the southeastern area was in surplus but that in the north‐west was in deficit. The degree of ecological harmony was 1.414, which proves that the sustainable development state in Po‐yang Lake Nature Reserve was under sustainable status. In 2005, the ecological footprint efficiency was 8382 yuan/ha, and the agricultural ecological footprint efficiency was 3204 yuan/ha. The lowest ecological compensation was 1725 yuan per family or 403 yuan per person, and the equal ecological compensation was 3798 yuan per family or 888 yuan per person.


Using Stein's method techniques, we develop a framework which allows one to bound the error terms arising from approximation by the Laplace distribution and apply it to the study of random sums of mean zero random variables. As a corollary, we deduce a Berry-Esseen type theorem for the convergence of certain geometric sums. Our results make use of a second order characterizing equation and a distributional transformation which is related to zero-biasing. 1. Background and Introduction Beginning with the publication of Charles Stein's seminal paper Stein (1972), probabilists and statisticians have developed a wide range of techniques based on characterizing equations for bounding the distance between the distribution of a random variable X and that of a random variable Z having some specied


Peers influence the people that we are attracted to and who we choose as dating and sexual partners. Peer ratings of attractiveness have been found to alter attractiveness ratings among individuals. Our study examines the effect of peer influence on perceptions of possible dating and sexual partners across genders in college students. Male and female undergraduate students were shown a series of pictures representing potential romantic partners with and without peer ratings of attractiveness. Participants were asked to rate the potential partners on physical attractiveness and likelihood of dating or sexually interacting with the partner. In addition, participants also rated the extent to which the potential partner would find them attractive and desirable as a sexual or dating partner. Individuals shown potential partners deemed highly attractive by peers found the potential partner to be more attractive than partners shown without peer ratings. Higher ratings of attractiveness were also associated with higher likelihood to date the partner for both genders. Lastly, self-desirability as a dating or sexual partner was predicted from appearance self-esteem and appearance comparison self-esteem. Our findings suggest that peer influence affects individuals' choices in dating and sexual partners among college students. PEER INFLUENCE AND POTENTIAL PARTNERS 4 List of Tables and Figures Table 1: Overall Means and Standard Deviations of Dependent Variables .................. 40 Table 2: Correlation Matrix for Self-Desirability and Self-Esteem Measures .............. 41 Figure 1: Gender and Peer Ratings Bar Graph .............................................................. 42 PEER INFLUENCE AND POTENTIAL PARTNERS 5 Effect of Peer Influence on Attraction to Potential Partners Social interactions influence the selection of partners for romantic relationships. The process of dating and choosing romantic partners is an important task in any individual's life, but especially for young adults who are the most susceptible to social influence. Social influence is important for college-aged adolescents and young adults when they live for the first time without adult supervision. The lack of adult guidance and constant presence of peers causes young adults' decisions to be strongly influenced by peer feedback and actions. These young individuals often feel pressure to date or engage in sexual relations due to their peers (Martens et al., 2006). Both men and women react differently to peer pressure and use different factors in choosing potential partners. However, in both genders, peers greatly influence the choices an individual makes when choosing a potential romantic partner. Studies have looked at both the influence of peers' ratings of physical attractiveness on initial perceptions of attraction, and the differences between how men and women perceive individuals as partners (Castro, Hattori, Yamamoto, & de Araujo Lopes, 2014; Dunn & Doria, 2010). However, the relationship between the two has not been studied. To address this gap in the literature, the aim of the present study is to examine how peer influence and gender differences predict potential partner selection. Predictors of Attraction A variety of predictors of attraction have been studied to determine attraction to a potential partner. These factors vary depending on the individual as well as gender. There are differences between genders, for example, in personality preferences for potential partners. Women tend to prefer partners who are open and conscientious in comparison to PEER INFLUENCE AND POTENTIAL PARTNERS 6 men (Furnham & Tsoi, 2012). However, generally differences between mens' and womens' preferences in attraction focus on physical appearance versus resources, respectively (Eastwick & Finkel, 2008; Furnham & Tsoi, 2012). Women tend to prefer partners that have higher levels of education, cognitive ability, wealth, and ambition in comparison to men's preferences for partners (Furnham & Tsoi, 2012). Women also prefer partners who have better occupations. In comparison, men tend to prefer partners that are more physically attractive and have favorable genetic traits such as good health (Furnham & Tsoi, 2012). There are multiple explanations for the discrepancy in preferences between genders. Evolutionary psychologists have attributed women's preference for earning potential in a potential partner to subconscious attempts at finding protection for offspring (Eastwick & Finkel, 2008). The need for protection is further reinforced by women's lengthy investment of personal resources during pregnancy. Men's preference for physically attractive partners is attributed to subconscious attempts for the development of healthy offspring (Eastwick & Finkel, 2008). Men search for partners who will maximize their chances of having healthy children. In addition, men do not need to search for a partner with resources as they have the potential to reproduce without investing as much as a woman does when she reproduces. Another explanation for the differences in preferences is social role theory. Traditional social norms have constructed men as providers for their families, whereas women have had the role of homemakers (Eagly & Steffen, 1984). According to social role theory, these norms are created from observations of role performance between men and women (Eagly, Wood, & Diekman, 2000). From this perspective, women tend to PEER INFLUENCE AND POTENTIAL PARTNERS 7 seek men who can provide and supply the family with resources because women are viewed as more communal or nurturing and men as more agentic or independent. Therefore, women are socialized to want men who can provide for them, and thus find these partners to be more attractive as a long-term partner. Another predictor of attraction is similarity to the potential partner. Furnham and Tsoi (2012) had men and women fill out questionnaires related to preference of romantic partners. They found that attractiveness, as measured by social skills, body shape, looks, and ambition, was correlated with self-estimated appearance. Their findings suggest that both genders prefer partners that are similar in attractiveness to their own self-perceived attractiveness. This is consistent with the matching phenomenon, which states that people who are similar in levels of physical attractiveness will be attracted to each other for long-term relationships (Takeuchi, 2006). Similarly, both genders also prefer partners who are similar in social status, educational background, and individuals with strong religious or political beliefs value a partner with compatible views (Furnham & Tsoi, 2012). These similarities motivate mate selection and promote compatibility between romantic partners. Overall, compatibility is strongest for individuals with similar social backgrounds, ideological belief systems, and physical characteristics (Furnham & Tsoi, 2012). Strong compatibility and multiple similarities have been found to be a strong predictor of marital quality among romantic relationships (Furnham & Tsoi, 2012). Another factor that influences perceptions of attraction is the halo effect. The halo effect occurs when positive characteristics are automatically attributed to an individual with one favorable trait (Nisbett & Wilson, 1977). For example, if a woman discovers that a potential partner is wealthy then she may believe him to be intelligent, responsible, PEER INFLUENCE AND POTENTIAL PARTNERS 8 and driven. This may make him a more appealing romantic partner. The halo effect is also often applied to physical attractiveness such that those who are physically attractive are often more likable and worthy of praise (Anderson & Nida, 1978). This effect is much stronger with the opposite sex than within the same sex (Anderson & Nida, 1978). This may be an explanation for men's desire for physically attractive long-term romantic partners. If peers influence an individual to regard a potential partner as highly attractive, then the individual may view that potential partner as more appealing as a result of the halo effect. Overall, men and women differ in terms of criteria for short and long term romantic partners. Due to these differences, using peers to influence how attractive a potential partner is to an individual may change the perceptions of the potential partner as either a short or long-term partner differently across genders. Peer Conformity to Attraction Many studies have examined how peer feedback augments perceptions of attractiveness to a potential partner (e.g., Dunn & Doria, 2010; Waynforth, 2007). However, women use peers' information pertaining to attraction of a potential partner more so than men. Dunn & Doria (2010) found that when women were exposed to a photograph depicting a male surrounded by interested females, the male's physical attractiveness increased in comparison to the same male standing alone. This increase is even more prevalent if the partner is viewed as highly attractive (Waynforth, 2007; Yorzinski & Platt, 2010). This effect has been described as an act of mate-choice copying. Women engage in mate-choice copying when they view a man as more attractive when he is already in a committed relationship or when other women find him to be attractive. Women are also more willing to engage in a long-term relationship with PEER INFLUENCE AND POTENTIAL PARTNERS 9 the man featured in the photograph with a highly attractive partner than a man either alone or with an unattractive partner. Studies have even found evidence to suggest that women rate a man as more physically attractive if he is wearing a wedding band (Waynforth, 2007). In addition to mate-choice copying, women have also been found to augment physical attractiveness ratings depending on peer ratings. That is, if peers rate an individual as highly attractive, women are more likely to believe the individual is attractive and inflate their corresponding physi


is the mean for data transfer over a medium to interact their expressions with each other. The common mode of communication is vocal speech conversation. The main modes of communication are constraint to vocally disabled individuals. For the communication of such individuals various means of communication is suggested, which are called as sign language. Aim: The aim of sign language alphabets recognition is to provide an easy, efficient and accurate mechanism for automatic translation of static sign (determined by a certain configuration of hand) to textual version in kannada language. Problem Statement: The work presented in this paper goal to develop a system for automatic translation of static gestures of alphabets in kannada sign language. It maps letters, words and expression of a certain language to a set of hand gestures enabling an in individual to communicate by using hands gestures rather than by speaking. The system capable of recognizing sign language symbols can be used as a means of communication with hard of hearing people. Sign of the deaf individual can be captured, recognized and translated to words in kannada language for the benefit of blind people. Approach: It has been divided into two phases firstly, feature extraction phase which in turn uses histogram technique, Hough and Segmentation to extract hand from the static sign. Secondly classification phase uses neural network for training samples. Extreme points were extracted from the segmented hand using star skeletonization and recognition was performed by distance signature. Results: The proposed method was tested on the dataset captured in the closed environment with the assumption that the user should be in the field of view. This study was performed for five different datasets in varying lighting conditions. Conclusion: The developed system is focused with objective of reducing the communication gap between normal people and vocally disabled.


First paragraph: Since 1982 Ghana has enjoyed its longest period of sustained political stability since it gained independence in 1957.1 While several periods of its democratic journey have been interrupted by military incursions (including attempted coups d'etat, mutinies and the successful overthrow of democratically elected governments), post-1981 Ghana was transformed from being the 'sick state of West Africa', both economically and politically, to become a reference point for democratic practice and security sector governance processes. In a region beset by security challenges, several aspects of this 'success story' have yet to be documented. This paper addresses this lacuna concerning Ghana's security sector reform processes and how they have influenced security sector governance dynamics, examining some of the changes in the fundamental structures of power and governance behind Ghana's transformation. To this end, the paper analyses a particularly significant policy intervention: the re-establishment of the Police Council under the 1992 constitution and the contradictions in both how the institution has functioned over time and how it has contributed to the manner in which the Ghana Police Service (GPS) is governed. To appreciate the developments that have contributed to what this paper argues are first steps in a genuine case of deepening democratic control of the security sector, it is necessary to examinethe history of the incremental changes that brought it about.

Mixed reality, which combines virtual images and real-world environment, can be used to visualize exercises on Aerial Weapon Scoring System (AWSS) air-to-ground with much lower risk. This research aims to develop a model system and a visualization technique using combination of augmented reality and virtual reality technology that able to view the results in the training field with the following specifications. The virtual image is built using 3D software and graphics library, while the real environment is a printed map as marker. The marker is tracked by using Augmented Reality (AR) and be viewed using Virtual Reality(VR) headset. The system will show firing animations as well as accuracy score, rocket angle and rocket direction. Once the marker is recognized by the system, its visualization can be viewed using the VR headset. This system is intended for military air-to ground rocket firing training by jet fighters that will aid the pilots in getting the results of exercises from various perspectives and allow the its user to collaborate with each other. These capabilities, we believe, will produce analysis which pilots can use to improve on the next exercises as well as increase the safety of Range Safety Officer (RSO) during exercise.


Identifying a natural substance produced by a living organism is only one of the very first steps towards the development of a new drug. Many molecules which were aimed at therapeutic goals and developed by pharmaceutical companies have in fact been discovered in academic research laboratories. The elaboration of a new drug is always a continuum from basic research toward applied research, and often from public research toward private research. Making these drugs straight from natural substances frequently confronts us with the problem of finding the raw materials. Numerous teams all over the world are facing the difficulties linked to the synthesis of these complex natural molecules.This PhD thesis relates the story of the milestones in the research of natural molecules for medicine through the successes and failures of scientists who put their energy, imagination, tenacity and patience into Science in order to overcome obstacles and discover new molecules for therapeutic use.It also presents a complementary work which consists in developing a database of useful plants in cancer fighting as part of a project of scientific vulgarisation.The discussion is about the part of chance in scientific discovery through the example of Pierre Potier.

A book entitled 'University Students who Cannot Calculate Fractions' published at the end of 1990s in Japan (edited by Okabe k. et. al, 1999) aimed to disclose the mathematical level of Japanese University Students by testing them with primary and secondary school level math quizzes. The 20% of them could not even solve fraction questions that children learn at primary school. This fact is indeed problematic for them to study Economics in higher education. Our study thus investigated how Japanese mathematics education has improved after 20 years of this book publication by testing university students with the same math questions used in the previous survey. The results were indifferent from the previous ones proving that the mathematics education in Japan was not innovated in these 20 years. Our paper explored what kinds of mathematical knowledge would disturb the current Japnese university students for understanding fundamental subjects such as Macro and Micro Economics. The results clarified the mathematical components they felt difficulty for understanding as well as their feelings of dislike for math. They are in the category of basic mathematical knowledge used in Economics, meaning that the education of this field is not sufficient and adequate for Japanese university students. This category is characteristic for Japanese university`s curriculum,called Economic Mathematics.

Abstract Although the further education (FE) sector can be characterised in many ways, there has been little attempt to consider the presence of shared mental models or 'dominant logics' among those involved in strategic management of FE colleges. Developed from interview-based research with principals, governors and Senior Management Team (SMT) members in 25 FE colleges, the authors identify three dominant logics which function as filters through which top management within FE colleges create strategic intent as well as characterise and manage proactive and imposed change.

Thin films comprising CdTe and Te as a secondary phase were obtained.


Currently, with the rapid development of 4G, most urban outdoor areas have been well covered with LTE signal, which provides the possibility to use LTE on land for positioning navigation system as a substitute of global navigation satellite system (GNSS). Because of cost and implementation difficulty, Minimization of Drive Tests (MDT) was proposed in LTE Release 10. It utilizes the LTE user equipment to feedback the measurement report of reference signal receiving power (RSRP) for the network optimization, which makes the LTE fingerprint-based positioning system possible. However, due to the mobile diversity, user habit and complicated channel, the user equipment (UE) RSRP difference is a non-ignorable problem that affects the positioning accuracy both in the online phase and offline phase. Therefore, in this paper, we propose an UE RSRP difference elimination method based on Multidimensional Scaling (MDS) algorithm. By using the relative RSRP difference between each two mobile terminals, we eliminate the RSRP difference both in the offline phase and online phase. We implemented the proposed method in a dense urban area and evaluated its performance. The experiment results indicated that the proposed method could effectively eliminate the UE RSRP difference and improve the positioning accuracy for LTE fingerprint-based positioning system.


Piper betle L., an evergreen perennial climber from the family Piperaceae, is an important medicinal plant in Malaysia. Despite its importance, knowledge on its propagation is still lacking. The present study was conducted to explore the feasibility of in vitro and in vivo systems of propagation. Sterilization of explants prior to in vitro procedures was carried out in 20% Clorox for 20 minutes. In vitro culture medium with 1.0 mg/L BAP was the best medium for shoot production. The study also examined in vivo rooting of cuttings and growth performance as affected by different indole 3 butyric acid (IBA) treatments and different nitrogen rates (0, 50 100, 150 kg/ha) and shade levels (0%, 30% and 50 %). Morphological parameters were recorded at 30, 60 and 90 days after planting. Semi-hardwood cuttings treated with 2000 mg/L IBA showed the best rooting performance (100%). Plants were significantly taller in treatment at 50 % shade and 100 kg N /ha. At first (H1), second (H2) and third (last) (H3) harvests, maximum height for each harvest was recorded at 70, 105.67 and 184.67 cm respectively. The number of branches was highest at 26.00 from H3, followed by H2 (10.33) and H1 (6.00). The number of leaves from H1, H2 and H3 harvests were 18.00, 46.33 and 171.00 respectively. The total leaf area recorded from H1, H2 and H3 were 653.17, 4108.28 and 10401.17 cm2 respectively. The fresh weight of leaves were recorded at 18.12 g (H1), 91.07 g (H2) and 185.15 g (H3), while the dry weight of leaves were recorded at 21.55 g (H3) 10. 91 g (H2) and 2.40 g (H1), significantly higher at 30 % shade with 100 kg N/ha. With respect to physiological parameters, photosynthesis (PR) and transpiration (TR) rates and stomatal conductance (SC) increased with increasing light intensity with treatment at 30 % shade and 100 kg N/ha giving the highest PRof 10.13 μmol CO2 / m2 /s, SC 0.13 mol/m2/s dan TR 1.60 μmol/m2/s. Chlorophyll content (a and ab) did not show any significant difference in the 30% and 50 % shade levels (1.55 and 1.49 mg/cm2) but was highest at 100 kg N/ha (1.76 mg/cm2). Chlorophyll b was highest at 50% shade which suggests that chlorophyll-a biosynthesis in relation to chlorophyll-b was significant in low light intensity. Total phenolic content (TPC) (highest at 1.19 mg (GAE)/g), total flavonoid content (TFC) (highest at 128.13 mg Quercetin/g) and antioxidant activities (DPPH) (highest at 85.15%) and FRAP 7.87 μmol Fe(ll)/g dry) were highly significant in the control treatment.


The usage of Autonomous Underwater Vehicles (AUVs) in scientific and industrial applications has increased in the last decade. In many applications the usage of fleet of heterogeneous assets is a key requirement. Their coordination and cooperation require high performance in terms of communication and information sharing. MANgO presents a federated world model operating over an underwater acoustic network through the networking capabilities provided by the SUNSET Software Defined Communication Stack (SDCS). It provides a method to transparently synchronise the local World Model (WM) of a vehicle with the rest of the heterogeneous team. The performance of the proposed architecture is demonstrated and compared with previous approaches using simulation and hardware-in-the-loop tests. Results show an improvement in the performance of at least 30% as well as the ease of integration with a variety of heterogeneous platforms.


This paper presents the performance of maximum utilization of electrical energy by using demand side management. Load management in a feeder is very important term to understand to stable load shape. For the stability of load shape we have to manage the demand side. For managing the load (demand) we use demand response. The problem of surrounding occurred is that the continuously disturbances on load side within a day. Sometimes, in a day the load fluctuations is maximum and sometimes it becomes too low.Due to which generation or supply side cannot fulfill all these load demands of consumers within a day. Objective of this paper is the maximum utilization of electrical energy and by developing the load shift algorithm. The optimum utilization of electrical energy is need of time and for that in this paper we are using load shifting technique under demand side management by using Artificial Neural Networks (ANN) for minimizing the load at peak time and utilize the unutilized loading valley time. Methods by which we can manage the demand side are peak clipping, load shifting, load addition, valley clipping, demand response. In this system we are using the Artificial Neural Network (ANN) technique to manage the demand side. It is a self decision making system which also used for bidirectional communication.We present a simple accurate system to manage electricity load with ANN.


Tropical forests cover large parts of the Earth's land surface. These forests hold an enormous biodiversity, and they are disappearing at an alarming rate [1]. Deforestation occurs very quickly in developing countries, the main distribution locations of tropical forests. An example in Vietnam, according to 2005 report conducted by the Food and Agriculture Organization of the United Nations (FAO), Vietnam has the second highest rate of deforestation of primary forests in the world, second only to Nigeria [2]. As of 2005, 12,931,000 hectares (the equivalent of 39.7% of Vietnam's land cover) was forested, although only 85,000 hectares (0.7% of the land cover) was primary forest, the most biodiverse form of forest [3]. Therefore, developing a method of surveying and monitoring tropical forest frequently is very necessary. Monitoring tropical forest frequently on the ground is very difficult because of complex terrains and expanse of the forest; thus remote sensing images have been widely applied as an important tool for mapping and monitoring forest. Forest mapping by remote sensing data at cover global scale include FRA 2000 by FAO using SPOT Vegetation data, Global Forest Mapping (GRFM/GBFM) Program by JAXA using JERS-1 SAR data. However, the broad categories mapped by these programs fail to deliver valuable and useful information on the variation within the tropical forest environment [4]. Forest mapping using high resolution multi-temporal optical images has been presented in several works e.g. ([4], [5], [6], [7]). But collecting clear high-resolution multi-temporal optical images in tropical regions is very difficult due to the neardaily presence of clouds. The problem is compounded by low temporal resolution of the associated high spatial resolution satellites. Due to its ability to penetrate clouds, microwave remote sensing has proved useful in forest mapping as shown in studies including ([8], [9], [10], [11], [12], [13]). In spite of that, using only microwave data to make a complete forest map has many limitations. The principal uses of radar will be to map forest structure and moisture, this information is largely complementary to that obtained by optical techniques [14]. However, the studies about combination of optical and radar images for forest mapping is not so many, some of them about using synergism of SAR and optical data for land use classification, including some forest types in categories table with limited number of forest classes ([15], [16]). In short, there are some contradictions between spatial resolution and repeat cycle of optical remote sensing data: Optical Moderate Resolution Images (like MODIS, MERIS) have a good repeat cycle, but resolution is too coarse for local studies; on the other hand, Optical High Resolution Images have good resolution, but repeat cycle is too long. Therefore, it is very difficult to separate between Forest and growing Paddy or Cropland because it is not easy to collect multi-temporal data for one year cycle to describe phenology of objects. Microwave data can separate Forest from Crop types and it can be used to analyze structure of forest to complement information for optical data. ALOS satellite of Japan was launched successfully on January 24 2006. It has both microwave and optical sensor. With high resolution (~10m), this data will be very useful for land studies including forest studies in local scale. The study of combination between optical and microwave data also becomes more feasible. Therefore, this study presents a possibility to improve accuracy of tropical forest mapping by combination of optical and microwave images of ALOS. To support for managing reforestation activities and preserving existing natural forest, discrimination of Planted Forest and Natural Forest is one of the most important purposes of this study. This study will not discuss biomass estimation and wood volume estimation, due to the lack of ground truth measurement data. Cloud removal is a sub-title but it also is an important part of this study.


Up to date, the life time of experimentally demonstrated entangled states has been limited, due to their fragility under decoherence and dissipation. Therefore, they are created under strict isolation conditions. In contrast, new approaches harness the coupling of the system to the environment, which drives the system into the desired state. Following these ideas, we present a robust method for generating steady state entanglement between two distant atomic ensembles. The proposed scheme relies on the interaction of the two atomic systems with the common vacuum modes of the electromagnetic field which act as an engineered environment. We develop the theoretical framework for two level systems including dipole-dipole interactions and complement these results by considering the implementation in multi-level ground states.


In this paper, we introduce a new approach for fitting rectangular boxes and cubes given as a set of voxels in a three-dimensional voxel space. This extends our work on fitting rectangles and squares described in H. Suesse et al, (2001) to three dimensions. It is also based on our normalization method published in K. Voss et al (1997) and (1999). Here we also encounter the problem of normalizing the rotation as it is necessary for rectangles and squares, but here we have two degenerate cases to handle. The first one are cubes, the second one are rectangular boxes with two edges of equal length and the length of the third edge different from them. Our method delivers good fitting results, even if the boxes are heavily distorted for example by cutting-off vertices.


Learning Design is the ordinance used to implement the learning process. The concept of learning design was first used in World War II and beyond. According to Jerrold E.

Demand response (DR) programs are developed to assist in reducing total power consumption, peak shifting and reduce peak period pressure on the utility infrastructure using various strategies. This paper presents common home appliances models that are suitable to control when participating in demand response (DR) programs. The empirical models developed for thermal loads and shiftable loads provide load profiles for a certain time period based on initial set points, tolerances ranges, and some physical properties of the medium. The proposed models are developed in Matlab simulation environment and various case studies are conducted for different input variations and set points. Test results show acceptable performance from the developed models for varying outer temperatures and the set point limits. The results also show that lower set points for cooling devices resulted in higher power consumption and that tolerance ranges affected the indoor temperatures of simulated home.


Provided is a wind power generation system intending to suppress an increase of torque when a voltage in a utility grid is restored, and to reduce a load to devices due to the torque. The wind power generation device is provided with a blade control unit 22 configured to control a pitch angle of wind turbine blades. The blade control unit 22 controls the pitch angle of the wind turbine blades such that a rotation speed of the power generator 6 becomes equal to or greater than a synchronous rotation speed when the power control unit 21 de-actuates the operations of the converter 14 and the inverter 16, and controls the pitch angle of the wind turbine blades such that the pitch angle matches a target pitch angle that is determined based on one of a wind speed, a rotation speed of the power generator 6, and a requested output power when the power control unit 21 re-actuates the operations of the converter 14 and the inverter 16.

This study presents the seismic response of low-to-high rise open ground story frames strengthened using buckling-restrained braces (BRBs). 4-story, 8-story and 20-story RC frames are considered for the seismic performance evaluation at the unstrengthened stage have been considered as the study frames. A design procedure has been proposed to determine the BRB sizes required for the target design base shear of the study frames. The seismic performance of these strengthened frames is evaluated numerically using a computer software SAP2000. The modelling technique adopted for BRBs and frame members are discussed, Linear modal analyses are carried out to determine the mode shapes and time periods of the strengthened frames. Nonlinear static and dynamic analyses are carried out to investigate the lateral strength, failure mechanism, interstory drift response and residual drift response of the study frames.


We are addressing here the problem of dynamic interactions between vision-guided mobile robots. We propose here to represent the information about the dynamic capabilities of a robot by a geometric object that we call the dynamic map (DM). We show how the DM can be generated from a dynamic model of a robot and provide an example in the case of a simple car-like vehicle. Finally, a simple planning strategy using this DM is presented.

Jet pumps, driven by a Primary-Loop Recirculation (PLR) Pump, have been widely used in Boiling Water Reactor (BWR) plants to recirculate the reactor core coolant. A jet pump consists of a driving nozzle, a bell-mouth, a throat and a diffuser. The improvement of the jet pump efficiency for BWR plants brings an economic advantage because it reduces the operating power cost of the PLR pump. In order to improve the efficiency of the BWR jet pump, a 1/5 scale jet pump test loop for BWR plant was used and intensive tests were conducted focusing on the types of driving nozzles and shapes of the throat. These test data were used for CFD flow analysis code verification. The analytical data showed good agreement with the test results. After the analytical model verification, improvement of jet pump efficiency was conducted. It was shown by the CFD analysis that the peak efficiency of the improved jet pump will be 36% with the tapered throat.


Background. The use of expanded criteria donors (ECDs) in cadaveric renal transplantation is increasing in the US.We assess the economic impact of the use of ECDs to the Medicare end stage renal disease program. Methods. The United Nations for Organ Sharing renal transplant registry was merged to Medicare claims data for 42,868 cadaveric renal transplants performed between 1991–1996 using USRDS identifiers. Only recipients for whom Medicare was the primary payer were considered, leaving 34,534 transplants. An ECD was defined as (1) age ≤5 or ≥55 years, (2) nonheart-beating donors, donor history of (3) hypertension or (4) diabetes. High-risk recipients (HRR) were age >60 years, or a retransplant. Medicare payments from the pretransplant dialysis period were projected forward to provide a financial "breakeven point" with transplantation. Results. There were 25,600 non-HRR transplants, with 5,718 (22%) using ECDs, and 8,934 HRR transplants, of which 2,200 (25%) used ECDs. The 5-year present value of payments for non-ECD/non-HRR donor/recipient pairings was $121,698 vs. $143,329 for ECD/non-HRR pairings (P <0.0001) and, similarly was $134,185 for non-ECD/HRR pairings vs. $165,716 for ECD/HRR pairings (P <0.0001). The break even point with hemodialysis ranged from 4.4 years for non-ECD/non-HRR pairings to 13 years for the ECD/HRR combinations but was sensitive to small changes in graft survival. Transplantation was always less expensive than hemodialysis in the long run. Conclusions. The impact of ECDs on Medicare payments is most pronounced in high-risk recipients. Cadaveric renal transplantation is a cost-saving treatment strategy for the Medicare ESRD program regardless of recipient risk status or the use of ECDs.

In this paper a medical robot based on a 3-RPS parallel platform is presented for providing correct screw path in transpedicular fixation surgery. For improving the accuracy of the robot, a calibration approach for 3-RPS with CMM (Coordinate Measuring Instrument) data is developed. Sensitivity analysis of the error source had been done with Monte-Carlo techniques. The results show that the length errors of the joint-links are main contribution to the output error of the 3-RPS parallel manipulator; and the secondary factor is the radius error of the static and the moving platform. Based on above analysis, the calibration model of the inverse kinematics was established and the mono-branched calibration method was used. The presented method has high identification accuracy for length error of the chain. Based on the identification parameters, the results show that the method can improve the 3-RPS output accuracy.


To research the effects of heterogeneous mouse cumulus cells (mCCs) on in vitro maturation of bovine denuded oocytes(DOs) and its development after parthenogenesis, bovine denuded germinal vesicle (GV) stage DOs were co-cultured in vitro with a mCCs monolayer in this study. The effect mechanism of cumulus cells on bovine DOs after in vitro maturation(IVM) and parthenogenesis were also discussed, and this could help to provide experimental bases for increasing maturation rate of bovine oocytes in vitro. Bovine oocytes were divided into four groups, namely COCs (cumulus-oocytes complexes) group, DOs+bCCs (bovine cumulus cells) group, DOs+mCCs group and DOs group. The extruded rate of oocytes in different groups of first polar body, glutathione (GSH) content and parthenogenetic development of MⅡ stage oocytes, relative expression levels of bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) mRNA of oocytes were detected after in vitro mature for 22~24h. The results showed that (1) Nuclear maturation rate of DOs+mCCs group and DOs+bCCs group [(68.48±5.71)%, (71.00±4.27)%] were significantly lower than that of COCs group (84.70±3.41)% (P0.05), but significantly higher than that of DOs group (54.26±5.03)% (P0.05); After parthenogenetic activation the GSH content and blastocyst rate of MⅡ oocytes of DOs+mCCs group [(2.48±0.24)pmol/oocyte, (44.19±4.03)%] were similar to those of DOs+bCCs group [(2.49±0.18)pmol/oocyte, (48.57±5.20)%] and DOs group [(2.40±0.17)pmol/oocyte, (43.47±7.34)%], but were all significantly lower than those of COCs group [(9.67±0.18)pmol/oocyte, (59.93±6.13)%)](P0.05), and cleavage rate of different groups showed no significant difference [(98.85±4.32)%, (92.11±2.00)%, (95.40±4.11)%, (93.18±3.19)%] (P0.05); (3)Relative expression levels of BMP15 and GDF9 mRNA of DOs+mCCs, DOs+bCCs and COCs group were all significantly higher than that of DOs group (P0.05), but relative expression levels of GDF9 mRNA of DOs+mCCs and COCs group were significantly higher than that of DOs+bCCs group (P0.05). The result indicated that mCCs could improve nuclear maturation rate and BMP15, GDF9 mRNA relative expression levels of bovine DOs, but could not enhance cytoplasmic maturation of DOs and parthenogenetic embryo development of MⅡ oocytes. It's suggested that cumulus cells can promote bovine oocytes nuclear maturation in vitro through some paracrine factors, and the effects of these factors may have no species specificity.

A ratchet fracture accident of driving shoveling blade was analyzed by means of chemical composition analysis,fracture analysis,metallographic examination and hardness distribution testing of carburized layer.The analysis results indicated that the main fracture reason of the ratchet was overheating.Carbon eliminated at the surface of ratchet and grain was growing and coarsening because of overheating and then quenching cracks were produced at the surface of ratchet.Ratchet bore excess impact and then fracture formed on the surface of ratchet.


The results into investigations of the decomposition of an anthraquinone dye (polan blue E2R) in an aqueous solution induced by ozone, hydrogen peroxide and UV radiation are discussed in the paper. The effect of the ozone dose and concentration, as well as the temperature on decolouration at different initial dye concentrations, were investigated. Low ozone concentrations enabled its better utilisation in the reaction with the dye, although the process rate was slow. An increase of gas flow rate and ozone concentration at the reactor inlet caused a decrease of ozone consumption from 80% to 49%. The hydrogen peroxide concentration from 0.05 to 0.1 mol/dm3 allowed us to obtain a 45% decolouration degree after 48 hours, with the process proceeding most quickly in the first 2 hours. It was found that the yield of anthraquinone dye photolysis in the aqueous solution was affected by both the power of the UV lamp and the character of the light which it emitted. It appeared most advantageous to use monoenergetic radiation in the UV range below 310 nm.
