    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    For the natural environment preservation, effective utilization of resources, and maintenance of the ecosystem, an international cooperation model was proposed for the environmental harmony type green technosystem. A comprehensive evaluating analysis of a green forest resource, etc. as the global resource, and an intensive extraction of subjects and needs was made. The analysis was conducted of technical possibility and abstract business development effects toward the industrialization with high values added which is in harmony with the environment. As a case study, the Papua New Guinea area, Malaysia was selected and re-evaluated. For this typical tropical forest area, a new technical system was studied based on the natural environment, industry/economy, social/cultural assessment, etc., and a model for industrializing new international cooperation was proposed. For the model making for industrialization, various steps to be taken and conditions to be prepared were studied and arranged for the realization. Upon going ahead with the international technical cooperation, Japan, a large lumber consuming country, needs to always consider the fostering and effective use of lumber resource in particular. 27 refs., 28 figs., 30 tabs.

    Out of the R and D on the environmental harmony type combustion technology, the results of the project carried out in fiscal 1997 were summed up. In the site survey, etc., visits were paid to France, Spain, Greek, Germany, the U.K. and the U.S. to have discussions and examine the trend of research on the NOx removal catalyst and catalyst combustion. In the actual R and D, the R and D were conducted on zeolite base NOx removal catalyst, oxide composite base NOx removal catalyst, alumina base NOx removal catalyst, direct decomposition type NOx removal catalyst, catalyst combustion, etc. In the R and D of the catalyst combustion, durability under high gas flow flux was examined of PdO-Pt/Ba-Al203 catalyst developed for low temperature use, which indicated that durability and low temperature activity were heightened. As high temperature use catalyst, high temperature durability was examined of the developed Pd0-La/Gd-ZrO2 catalyst, which showed that the durability was favorable. 322 refs., 261 figs., 55 tabs.

    The research and development were conducted jointly with Europe of an environmental harmony type high efficient catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. In the research and development of NOx removal catalyst such as zeolite base, reformation of mostly mordenite was done by ion exchange, ion implantation, skeleton element substitution, etc. A possibility was found out of applying the membrane formation method except ion implantation as reforming means. In the R and D of the complex oxide base NOx removal catalyst, it was found that the catalyst carrying copper and silver on silica and layer clay compound under optimum conditions shows peculiarly high activity, and there is little decrease in the activity, but rather increase in it even under vapor existence. An evaluation was made of NO resolution of direct resolution element carrying noble metal electrolyte on solid electrolyte, finding out that the highest NO selectivity is shown with Pd as electrolyte and at a baking temperature of about 1300degC. Development of high- and low-temperature catalysts was also made. 417 refs., 286 figs., 63 tabs.

    This project is aimed at internationally cooperating in the R and D of industrial technology and improving industrial technology of Japan. For it, the following three technologies were investigated: 1) environmental preservation technology using biotechnology, 2) technology for effective use of unused hydrocarbon resource, 3) technology for development of environmental harmony type catalyst. In 1), a survey was conducted of applicability of biological surfactant to prevention measures of pollution by heavy distillate. It showed that part of the biological surfactants is reaching a stage of its being industrially produced by gene recombination bacteria, but as a whole, biosynthetic genes have hardly been elucidated. In 2), a survey of high-grade treatment technology of petroleum coke was made. It pointed out that it is necessary to develop a technology which makes the most of features of petroleum coke and allows defects. In 3), scientists and engineers of Japan and Europe searched for themes on which they can jointly study in the fields of NOx removal catalyst, up-grading of fuel, and development of catalyst combustion of fuel. 287 refs., 136 figs., 128 tabs.

  7. Harmony in Gitksan

    What types of consonants are transparent in vowel harmony in Gitksan has been little understood. Previous studies suggest that it is translaryngeal harmony, where the qualities of unstressed suffixal vowels are harmonized with the ones of last stem vowels, apparently skipping the stem-final laryngeal stop and laryngeal fricative [Rigsby, unpublished manuscript, University of Queensland, Australia, 1986; Rigsby and Ingram, International Journal of American Linguistics 56, 251-263 (1990)]. However, our original data show that harmony takes place when the stem-final consonant is uvular as well. It suggests that it cannot simply be analyzed as laryngeal transparency, but it could be reanalyzed as [+low] transparency. The present study examines cross-consonantal vowel harmony through acoustic experiment. It is predicted that there is a significant difference in formant values between the vowels across uvular or laryngeal consonants versus the ones across the other consonants. New data from an Eastern Gitksan speaker (female, 72) and its analysis will be presented. Implications for locality of vowel harmony as well as for the phonological treatment of consonantal transparency will be discussed. [Work supported by SSHRC.

  8. Right to Place: A Political Theory of Animal Rights in Harmony with Environmental and Ecological Principles

    Full Text Available The focus of this paper is on the “right to place” as a political theory of wild animal rights. Out of the debate between terrestrial cosmopolitans inspired by Kant and Arendt and rooted cosmopolitan animal right theorists, the right to place emerges from the fold of rooted cosmopolitanism in tandem with environmental and ecological principles. Contrary to terrestrial cosmopolitans—who favour extending citizenship rights to wild animals and advocate at the same time large-scale humanitarian interventions and unrestricted geographical mobility—I argue that the well-being of wild animals is best served by the right to place theory on account of its sovereignty model. The right to place theory advocates human non-interference in wildlife communities, opposing even humanitarian interventions, which carry the risk of unintended consequences. The right to place theory, with its emphasis on territorial sovereignty, bases its opposition to unrestricted geographical mobility on two considerations: (a the non-generalist nature of many species and (b the potential for abuse via human encroachment. In a broader context, the advantage of the right to place theory lies in its implicit environmental demands: human population control and sustainable lifestyles.

    Geographical Information Systems (GIS) have been gaining a growing interest in Turkey. Many local governments and public agencies have been struggling to set up such systems to serve the needs and meet public requirements. Urban life shelters the advertisement reality which is presented at various places, on vehicles, shops etc. in daily life. It can be said that advertisement is a part of daily life in urban area, especially in city centers. In addition, one of the main sources of revenue for municipalities comes from advertising and notices. The advertising sector provides a great level of income today. Therefore advertising is individually very important for local governments and urban management. Although it is valuable for local governments, it is also very important for urban management to place these advertisement signs and billboards in an orderly fashion which is pleasing to the eye. Another point related to this subject is the systematic control mechanism which is necessary for collecting taxes regularly and updating. In this paper, first practical meaning of notice and advertisement subject, problem definition and objectives are described and then legal support and daily practice are revised. Current practice and problems are mentioned. Possibilities of measuring and obtaining necessary information by using digital images and transferring them to spatial databases are studied. By this study, a modern approach was developed for urban management and municipalities by using information technology which is an alternative to current application. Criteria which provide environmental harmony such as urban beauty, colour, compatibility and safety were also evaluated. It was finally concluded that measuring commercial signs and keeping environmental harmony under control for urban beauty can be provided by Digital Photogrammetry (DP) technique and GIS capabilities which were studied with pilot applications in the city center of Ankara.

  15. Exceptionality in vowel harmony

    Science.gov (United States)

    Szeredi, Daniel

    Vowel harmony has been of great interest in phonological research. It has been widely accepted that vowel harmony is a phonetically natural phenomenon, which means that it is a common pattern because it provides advantages to the speaker in articulation and to the listener in perception. Exceptional patterns proved to be a challenge to the phonetically grounded analysis as they, by their nature, introduce phonetically disadvantageous sequences to the surface form, that consist of harmonically different vowels. Such forms are found, for example in the Finnish stem tuoli 'chair' or in the Hungarian suffixed form hi:d-hoz 'to the bridge', both word forms containing a mix of front and back vowels. There has recently been evidence shown that there might be a phonetic level explanation for some exceptional patterns, as the possibility that some vowels participating in irregular stems (like the vowel [i] in the Hungarian stem hi:d 'bridge' above) differ in some small phonetic detail from vowels in regular stems. The main question has not been raised, though: does this phonetic detail matter for speakers? Would they use these minor differences when they have to categorize a new word as regular or irregular? A different recent trend in explaining morphophonological exceptionality by looking at the phonotactic regularities characteristic of classes of stems based on their morphological behavior. Studies have shown that speakers are aware of these regularities, and use them as cues when they have to decide what class a novel stem belongs to. These sublexical phonotactic regularities have already been shown to be present in some exceptional patterns vowel harmony, but many questions remain open: how is learning the static generalization linked to learning the allomorph selection facet of vowel harmony? How much does the effect of consonants on vowel harmony matter, when compared to the effect of vowel-to-vowel correspondences? This dissertation aims to test these two ideas

    Starting in the 17th century with Newton, color harmony is a topic that did not reach a consensus on definition, representation or modeling so far. Previous work highlighted specific characteristics for color harmony on com- bination of color doublets or triplets by means of a human rating on a harmony scale. However, there were no investigation involving complex stimuli or pointing out how harmony is spatially located within a picture. The modeling of such concept as well as a reliable ground-truth would be of high value for the community, since the applications are wide and concern several communities: from psychology to computer graphics. We propose a protocol for creating color harmony maps from a controlled experiment. Through an eye-tracking protocol, we focus on the identification of disharmonious colors in pictures. The experiment was composed of a free viewing pass in order to let the observer be familiar with the content before a second pass where we asked "to search for the most disharmonious areas in the picture". Twenty-seven observers participated to the experiments that was composed of a total of 30 different stimuli. The high inter-observer agreement as well as a cross-validation confirm the validity of the proposed ground-truth.

  17. Wastewater Treatment Optimization for Fish Migration Using Harmony Search

    2014-01-01

    Full Text Available Certain types of fish migrate between the sea and fresh water to spawn. In order for them to swim without any breathing problem, river should contain enough oxygen. If fish is passing along the river in municipal area, it needs sufficient dissolved oxygen level which is influenced by dumped amount of wastewater into the river. If existing treatment methods such as settling and biological oxidation are not enough, we have to consider additional treatment methods such as microscreening filtration and nitrification. This study constructed a wastewater treatment optimization model for migratory fish, which considers three costs (filtration cost, nitrification cost, and irrigation cost and two environmental constraints (minimal dissolved oxygen level and maximal nitrate-nitrogen concentration. Results show that the metaheuristic technique such as harmony search could find good solutions robustly while calculus-based technique such as generalized reduced gradient method was trapped in local optima or even divergent.

    2013-01-01

    Full Text Available The harmony search algorithm is a music-inspired optimization technology and has been successfully applied to diverse scientific and engineering problems. However, like other metaheuristic algorithms, it still faces two difficulties: parameter setting and finding the optimal balance between diversity and intensity in searching. This paper proposes a novel, self-adaptive search mechanism for optimization problems with continuous variables. This new variant can automatically configure the evolutionary parameters in accordance with problem characteristics, such as the scale and the boundaries, and dynamically select evolutionary strategies in accordance with its search performance. The new variant simplifies the parameter setting and efficiently solves all types of optimization problems with continuous variables. Statistical test results show that this variant is considerably robust and outperforms the original harmony search (HS, improved harmony search (IHS, and other self-adaptive variants for large-scale optimization problems and constrained problems.

    Full Text Available Two-sided assembly lines balancing problems are important problem for large-sized products such as cars and buses, in which, tasks operations can be performed in the two sides of the line. In this paper, Harmony Search algorithm is proposed to solve two-sided assembly lines balancing problems type-I (TALBP-I. The proposed method adopts the COMSOAL heuristic and specific features of TALBP in the Harmony operators – the harmony memory consideration, random selection and pitch adjustment – in order to maintain the local and global search. The proposed method is evaluated based on 6 benchmark problems that are commonly used in TALBP. The experiment results show that the proposed method work well and produces better solution than the heuristic method and genetic algorithm.

    Full Text Available A technique has been developed for predicting road traffic noise for environmental assessment, taking into account traffic volume as well as road surface conditions. The ASJ model (ASJ Prediction Model for Road Traffic Noise, 1999, which is based on the sound power level of the noise emitted by the interaction between the road surface and tires, employs regression models for two road surface types: dense-graded asphalt (DGA and permeable asphalt (PA. However, these models are not applicable to other types of road surfaces. Accordingly, this paper introduces a parameter estimation procedure for ASJ-based noise prediction models, utilizing a harmony search (HS algorithm. Traffic noise measurement data for four different vehicle types were used in the algorithm to determine the regression parameters for several road surface types. The parameters of the traffic noise prediction models were evaluated using another measurement set, and good agreement was observed between the predicted and measured sound power levels.

    Full Text Available Recent evolutions in Europe raise questions on the viability of the present economic and social model that defines the European construction project. In this paper, the author will try to explain the viability of institutional European model that sticks between free market mechanisms and protectionism. The main challenge for the EU is about the possibility to bring together the institutional convergence and the welfare for all Europeans. This is the result of the view, still dominant, of European politics elite, according to which institutional harmonization is the solution of a more dynamic and prosper Europe. But, economic realities convince us that, more and more, a harmonized, standardized Europe is not necessarily identical with a Europe of harmony and social cooperation. If „development through integration” seems to be harmonization through „institutional transplant”, how could then be the European model one sufficiently wide open to market, which creates the prosperity so long waited for by new member countries?

The Chinese authorities proposed a new course of ‘ecological civilization’ development. The authors analyze the issues that arise from the development of ecological civilization in China from the perspective of definition of the term ‘ecological civilization’ in the context of traditional Chinese culture, its relationship with traditional and modern understanding of the harmony and harmonious society, and development of legal regulations in the sphere of environmental protection. We provide the analysis of philosophical aspects of the emergence of ecological society, such as expansion of the Western anthropocentrism in the modern Chinese society, possibility of revival of ecological consciousness that is based on traditional Chinese culture, etc. The paper demonstrates the approach that was developed in the works of Chinese scholars regarding understanding of ecological civilization as a new stage of human society’s development that comes after industrial society. In conclusion, the authors propose to consider that approach as a necessary civilizational choice that is to be taken by the Chinese society.

  8. Two pathways ensuring social harmony

    Konrad, Matthias; Pamminger, Tobias; Foitzik, Susanne

    2012-08-01

    Reproductive division of labour is a characteristic trait of social insects. The dominant reproductive individual, often the queen, uses chemical communication and/or behaviour to maintain her social status. Queens of many social insects communicate their fertility status via cuticle-bound substances. As these substances usually possess a low volatility, their range in queen-worker communication is potentially limited. Here, we investigate the range and impact of behavioural and chemical queen signals on workers of the ant Temnothorax longispinosus. We compared the behaviour and ovary development of workers subjected to three different treatments: workers with direct chemical and physical contact to the queen, those solely under the influence of volatile queen substances and those entirely separated from the queen. In addition to short-ranged queen signals preventing ovary development in workers, we discovered a novel secondary pathway influencing worker behaviour. Workers with no physical contact to the queen, but exposed to volatile substances, started to develop their ovaries, but did not change their behaviour compared to workers in direct contact to the queen. In contrast, workers in queen-separated groups showed both increased ovary development and aggressive dominance interactions. We conclude that T. longispinosus queens influence worker ovary development and behaviour via two independent signals, both ensuring social harmony within the colony.

  9. Environmental modulators of type 1 diabetes mellitus

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available In genetically susceptible subjects, type 1 diabetes (T1D appears to be a chronic immune- mediated disease with a subclinical prodromal period characterized by selective loss of insulin-releasing pancreatic beta cells. However, only a relatively small proportion of genetically susceptible subjects progress to clinical disease, which indicates that environmental factors are needed to trigger and drive the disease process in genetically predisposed subjects. In this article we provide a selective review on environmental factors involved in the pathogenesis of T1D. Accumulating evidence suggests that the proportion of subjects with high-risk human leukocyte antigen (HLA genotypes has decreased over the last decades among patients with newly diagnosed T1D, whereas the proportion of those with low-risk or even protective HLA genotypes has increased. These findings indicate that increased environmental pressure is responsible for progression to clinical diabetes in patients with less genetic predisposition. The birth cohort studies indicate that the first signs of beta cell autoimmunity may be induced during infancy before age 3, which implies that dietary factors for beta cell autoimmunity and T1D may be active in that time period, during which early nutrition provides essential exogenous exposure. Progression to clinical T1D typically needs the combination of genetic disease susceptibility, a diabetogenic trigger, and a high exposure to a driving antigen. The triggers appear to be enteroviruses and rotaviruses as well as components of the infant diet including cows milk and gluten, while the Mediterranean diet appears protective. The only definite enterovirus responsible for T1D is congenital rubella, which may be complicated by late development of T1D. There is a temporal association between enteroviral infection and future development of antibodies resulting in T1D. Clinical studies indicate that islet cell antibodies develop 3 months after birth

  10. Generalised Adaptive Harmony Search: A Comparative Analysis of Modern Harmony Search

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Harmony search (HS was introduced in 2001 as a heuristic population-based optimisation algorithm. Since then HS has become a popular alternative to other heuristic algorithms like simulated annealing and particle swarm optimisation. However, some flaws, like the need for parameter tuning, were identified and have been a topic of study for much research over the last 10 years. Many variants of HS were developed to address some of these flaws, and most of them have made substantial improvements. In this paper we compare the performance of three recent HS variants: exploratory harmony search, self-adaptive harmony search, and dynamic local-best harmony search. We compare the accuracy of these algorithms, using a set of well-known optimisation benchmark functions that include both unimodal and multimodal problems. Observations from this comparison led us to design a novel hybrid that combines the best attributes of these modern variants into a single optimiser called generalised adaptive harmony search.

    1975-01-01

    Energy problems and harmony in international relation are closely related with world politics. Oil is destined to remain as the primary energy source for the time being. The situation of oil has different implications to the U.S. and U.S.S.R., oil producing countries, and consumer countries. The hasty attitude in the past to attain energy sufficiency must be avoided by all means. Congenial harmony is to be established in international relation to meet world energy requirement. This also applies to the case of nuclear power in future. (Mori, K.)

    2009-01-01

    Yesterday I spoke at a conference hosted by an organization called Melody for Dialogue, and it struck me that this organization has much in common with a movement that contributed to CERN’s foundation 55 years ago. That movement was called ‘Atoms for Peace’. Notice the similarity? What is it that melody and atoms have in common that they can be used to promote dialogue and peace? I believe that they are both expressions of something shared by all of humanity. Whatever culture we belong to, music is a part of it. And wherever in the world we’re from, we’re all curious about our surroundings. Science and music are two of the things that make us human. The theme of the conference was environmental awareness, and I told the participants that although CERN’s research won’t bring immediate solutions to the pressing environmental problems of the world, if it were not for similar curiosity-driven research in the past, much of w...

  16. Achieving harmony with oneself: life with a chronic illness.

    This paper presents partial findings of a larger research project focusing on what it means to live with a chronic illness. Getting in harmony with oneself is a movement towards, and a form of, acceptance of the chronic suffering and disease. Some patients achieve this level of acceptance, while for others the obstacles of everyday life make this movement towards acceptance difficult. Achieving harmony with oneself is conditioned by the existence of hope and spirit of life/life courage and by the pressure of doubts on this hope. Doubts can shake this hope so that instead of moving towards acceptance, the patient drifts towards hopelessness and despair. The research design is qualitative and uses a phenomenological-hermeneutic approach. A total of 18 patients were interviewed, divided into three groups of six patients diagnosed with 'type I' diabetes, colitis ulcerosa and patients with coronary occlusion in the rehabilitation phase. The goal of the research was to derive patterns/themes common to the three diagnosed groups regarding the patients' view of health and disease in connection with chronic illness and to elucidate the significance of this view for how the patients coped with everyday life. The research method is inspired by Paul Ricoeur.

    Air pollution is a novel risk factor for insulin resistance and occurrence of type 2 diabetes mellitus (T2DM), but the evidence is limited and diverse. Therefore, the aim of this study was to assess the effect of environmental air pollution on incidence of type 2 diabetes mellitus. In this study, we identified 102 published studies through a systematic data base search including ISI-Web of Science, EMBASE and PubMed. We searched the related literature by using the key terms including diabetes mellitus, air pollution, occupational and environmental pollution, gaseous, NO2, particulate matter pollutants PM2.5, and PM10. Studies in which diabetes mellitus, insulin resistance, air pollution, occupational and environmental pollution was discussed were included in the study. No confines on publication status, study design or language of publication were considered. Descriptive and quantitative information were extracted from the selected literature. Finally we included 21 publications and remaining studies were excluded. Air pollution is a leading cause of insulin resistance and incidence of type 2 diabetes mellitus. The association between air pollution and diabetes is stronger for traffic associated pollutants, gaseous, nitrogen dioxide, tobacco smoke and particulate matter. Exposure to air pollutants is significantly associated with increased risk of type 2 diabetes mellitus. It is suggested that, environmental protection officials must take high priority steps to minimize the air pollution, hence to decrease the incidence of type 2 diabetes mellitus.

    In the 1970s, Richard Voss and John Clarke researched the actual audio physical sound of music. There are three types of noise: white noise, 1/f noise, and Brownian motion noise (1/f 2 ). 1/f noise is found to be most pleasing to human ears. White noise is too random and Brownian noise is too correlated. Similarly, for 2-dimensional sources such as graphics and images, three characteristics of monotonous, harmony and muss are also observed. The 1/f fluctuation theory provides a good way to generate affective signals both for 1-dimensional and 2-dimensional signals. This paper provides an algorithm which can generate affective patterns or graphics and obey the criteria of affective information processing

    Type 1 diabetes is an autoimmune disease that results in a progressive (complete in most cases) destruction of insulin-secreting beta cells from Langerhans islets. Even if the autoimmune process becomes to be well known, no one is yet sure what specifically prompts the autoimmune response that destroys the body's ability to produce insulin. Etiology of this complex disease combines a genetic predisposition and still (almost) unknown environmental factors that trigger autoimmuninty specifically targeting beta cells. Genetic HLA predispositions are clearly identified. However, only few people with apparent genetic predisposition to type 1 diabetes actually end up getting the disease. Moreover, the remarkable increase of type 1 diabetes prevalence observed in numerous countries can not be explained by genetics. Because genetic factors can't predict alone the development of type 1 diabetes, environmental factors must be involved such as viral infections, toxins from food, cow milk during childhood (instead of breast feeding) or vitamin D deficiency. This paper aims at describing the role of the genetic predisposition and the environmental hypothesis which can be involved in the development of type 1 diabetes. We will conclude by briefly describing clinical trials targeting either the immune response or the potentially toxic environment.

  2. Harmonious colors: from alchemy to science

    Beretta, Giordano B.; Moroney, Nathan M.

    2012-01-01

    There is a very long tradition in designing color palettes for various applications, going back to at least the Upanishad. Although color palettes have been influenced by the available colorants, starting with the advent of aniline dyes in the late 1850s there have been few physical limits on the choice of individual colors. This abundance of choices exacerbates the problem of limiting the number of colors in a palette, i.e., in keeping them into a manageable quantity. For example, it is not practical for a car company to offer each model in hundreds of colors. Instead, for each model year a small number of color palettes is offered, each containing the colors for the body, trim, interior, etc. Another example is the fashion industry, where in addition to solid colors there are also patterns, leading to a huge variety of combinations that would be impossible to stock. The traditional solution is that of "color forecasting." Color consultants assess the sentiment or affective state of a target customer class and compare it with new colorants offered by the industry. They assemble a limited color palette, name the colors according to the sentiment, and publish their result. Textile manufacturers will produce fabrics in these colors and fashion designers will design clothes, accessories, and furniture based on these fabrics. Eventually, the media will communicate these forecasts to the consumers, who will be admired by their cohorts when they choose colors from the forecast palette, which by then is widely diffused. The color forecasting business is very labor intensive and difficult, thus for years computer engineers have tried to come up with algorithms to design harmonious color palettes, alas with little commercial success. For example, Johannes Itten's color theory has been implemented many times, but despite Itten's success in the Bauhaus artifacts, the computer tools have been of little utility. Indeed, contrary to the auditory sense, there is no known

  8. Robust Circle Detection Using Harmony Search

    2017-01-01

    Full Text Available Automatic circle detection is an important element of many image processing algorithms. Traditionally the Hough transform has been used to find circular objects in images but more modern approaches that make use of heuristic optimisation techniques have been developed. These are often used in large complex images where the presence of noise or limited computational resources make the Hough transform impractical. Previous research on the use of the Harmony Search (HS in circle detection showed that HS is an attractive alternative to many of the modern circle detectors based on heuristic optimisers like genetic algorithms and simulated annealing. We propose improvements to this work that enables our algorithm to robustly find multiple circles in larger data sets and still work on realistic images that are heavily corrupted by noisy edges.

    Full Text Available This article describes a case of gingival asymmetry with compromising aesthetics. A 25-year-old dental student presented to the department of prosthetic dentistry. She was concerned about the greyish transparency of the crown metal margin through the marginal gingiva. The crown was placed to restore her lateral incisor. A comprehensive examination revealed that this unaesthetic aspect was caused by a non-harmonious gingival architecture in the lateral incisor marked by an unaesthetic gingival Zenith. The treatment plan included a surgical crown lengthening followed by prosthetic therapy consisting in a Zirconia based crown replacing the old prosthesis. Thanks to a well-planned multi-disciplinary approach, the result was esthetically acceptable and the patient was satisfied.

  10. The Psychophysics of Harmony Perception: Harmony is a Three-Tone Phenomenon

    Directory of Open Access Journals (Sweden)

    Norman D. Cook

    2006-09-01

    Full Text Available In line with musical “common sense” (but contrary to the century-old tradition of musical psychophysics, we show that harmony is an inherently three-tone phenomenon. Previous attempts at explaining the affective response to major/minor chords and resolved/unresolved chords on the basis of the summation of interval dissonance have been notably unsuccessful, but consideration of the relative size of the intervals contained in triads leads directly to solutions to these historical problems. At the heart of our model is Leonard Meyer’s idea from 1956 concerning “intervallic equidistance” – i.e., the perception of “tension” inherent to any three-tone combination that has two intervals of equivalent size (e.g., the augmented chord. By including the effects of the upper partials, a psychophysical explanation of the perceived sonority of the triads (major>minor>diminished>augmented and the affective valence of major and minor chords is easily achieved. We conclude that the perceptual regularities of traditional diatonic harmony are neither due to the summation of interval effects nor simply arbitrary, learned cultural artifacts, but rather that harmony has a psychophysical basis dependent on three-tone combinations.

  11. Environmental implications of different circulation type classification methods

    The most important goal of synoptic climatology is to analyze the relationships between atmospheric circulation and surface environmental conditions; e.g. dust outbreaks, flash floods and air pollution episodes. The basic assumption assumes that the atmosphere can be partitioned to discrete circulation types as manifested by recurring map flow patterns. Since manual (subjective) classification can lead to different environmental implications as compared to automated (objective) classification, a comparison between a subjective and semi-objective classification was performed for the Eastern Mediterranean for 10 years (1995-2004). Among the 19 recurring synoptic types characterizing the circulation regime over the E.M., the overall frequencies of the 3 most common synoptic types - Red Sea Trough with eastern axis, Shallow Persian Trough and High to the West were similar for both classifications. The discrepancies on a day to day basis for these 3 types were 60, 53 and 69% respectively. However, for deep horizontal pressure gradient synoptic types, i.e. Deep Cyprus Low to the North and Cold Low to the West both classifications yielded the highest agreement (over 50%). Classification results of synoptic types having important environmental implications in the E.M., i.e. Red Sea Trough with Western Axis, Deep Persian Trough and Sharav Low to the West differed substantially (over 90% disagreement) for both methodologies. The first type is associated with torrential rain inducing flash floods, the second is responsible for long range transport of pollutants and the last is prone for dust outbreaks. In order to show the influence of atmospheric circulation on the smaller scale surface environment two fundamental approaches were used: the "circulation-to-environment" and "environment-to-circulation". These approaches were tested on three surface environment processes: air pollutants, desert dust intrusions and floods. Preliminary methods were examined to provide insights on

    To learn characteristics and their mutual relations of self-esteem, self-harmony and interpersonal-harmony of university students, in order to provide the basis for mental health education. With a stratified cluster random sampling method, a questionnaire survey was conducted in 820 university students from 16 classes of four universities, chosen from 30 universities in Anhui Province. Meanwhile, Rosenberg Self-esteem Scale, Self-harmony Scale and Interpersonal-harmony Diagnostic Scale were used for assessment. Self-esteem of university students has an average score of (30.71 +/- 4.77), higher than median thoery 25, and there existed statistical significance in the dimensions of gender (P = 0.004), origin (P = 0.038) and only-child (P = 0.005). University students' self-harmony has an average score of (98.66 +/- 8.69), among which there were 112 students in the group of low score, counting for 13.7%, 442 in that of middle score, counting for 53.95%, 265 in that of high score, counting for 32.33%. And there existed no statistical significance in the total-score of self-harmony and score differences from most of subscales in the dimention of gender and origin, but satistical significance did exist in the dimention of only-child (P = 0.004). It was statistically significant (P = 0.006) on the "stereotype" subscales, on the differences between university students from urban areas and rural areas. Every dimension of self-esteem and self -harmony and interpersonal harmony was correlated and statistically significant. Multiple regression analysis found that when there was a variable in self-esteem, the amount of the variable of self-harmony for explaination of interpersonal conversation dropped from 22.6% to 12%, and standard regression coefficient changing from 0.087 to 0.035. The trouble of interpersonal dating fell from 27.6% to 13.1%, the standard regression coefficient changing from 0.104 to 0.019. The bother of treating people fell from 30.9% to 15%, and the

  15. Ecology and energy: prospecting for harmony in the United States

    Anderson, T.L.; Leal, D.R.

    1991-01-01

    When energy resources are controlled by the political sector, environmentalists are pitted against exploration and development companies in a setting that encourages confrontation. The controversy has reached a high pitch in the battle over whether to allow exploration and development in the Arctic National Wildlife Refuge's 1.5 million-acre coastal plain. Geologists believe that the coastal plain contains between 600 million and 9.2 billion barrels of economically recoverable oil. The area is also an important habitat for wildlife. In response to a 1986 US Department of the Interior report recommending that the area be made available to oil and gas development, environmentalists mounted an effective campaign to block final approval in Congress. Although these kinds of confrontations suggest that exploration and development of oil and natural gas necessarily lead to environmental damage, this need not be the case. In fact, there are approaches that enable development to be carried out in a sensitive manner. For example, under certain conditions developers can use directional or slant drilling to prevent disturbance to fragile surface areas such as swamps and marshlands. Special applications, such as highly insulated platforms, have also been used to mitigate disturbance to fragile Arctic environments. Yet, environmental groups continue to battle companies over oil and gas exploration. We will argue that greater harmony between environmental amenities and oil and gas development is often prevented by government policies that give each side strong incentives to engage in a wasteful battle over the control of public resources. We will also suggest policy alternatives that promote cooperation by satisfying the goals of both economic efficiency and environmental integrity. (author)

    From the Main galaxy sample of the Sloan Digital Sky Survey Data Release 6, we construct two volume-limited samples with the luminosity -20.0 ≤ M r ≤ -18.5 and -22.40 ≤ M r ≤ -20.16, respectively, to explore the environmental dependence of the fraction of 'unconventional' galaxies: red late types and blue early types. We use the density estimator within the distance to the fifth nearest neighbor, and construct two samples at both extremes of density and perform comparative studies between them for each volume-limited sample. Results of two volume-limited samples show the same conclusions: the fraction of red late-type galaxies rises considerably with increasing local density, and that one of the blue early-type galaxies declines substantially with increasing local density. In addition, we note that bluer galaxies preferentially are late types, but the red galaxies are not dominated by early types.

    Perovskites are mixed-metal oxides that are attracting much scientific and application interest owing to their low price, adaptability, and thermal stability, which often depend on bulk and surface characteristics. These materials have been extensively explored for their catalytic, electrical, magnetic, and optical properties. They are promising candidates for the photocatalytic splitting of water and have also been extensively studied for environmental catalysis applications. Oxygen and cation non-stoichiometry can be tailored in a large number of perovskite compositions to achieve the desired catalytic activity, including multifunctional catalytic properties. Despite the extensive uses, the commercial success for this class of perovskite-based catalytic materials has not been achieved for vehicle exhaust emission control or for many other environmental applications. With recent advances in synthesis techniques, including the preparation of supported perovskites, and increasing understanding of promoted substitute perovskite-type materials, there is a growing interest in applied studies of perovskite-type catalytic materials. We have studied a number of perovskites based on Co, Mn, Ru, and Fe and their substituted compositions for their catalytic activity in terms of diesel soot oxidation, three-way catalysis, N 2 O decomposition, low-temperature CO oxidation, oxidation of volatile organic compounds, etc. The enhanced catalytic activity of these materials is attributed mainly to their altered redox properties, the promotional effect of co-ions, and the increased exposure of catalytically active transition metals in certain preparations. The recent lowering of sulfur content in fuel and concerns over the cost and availability of precious metals are responsible for renewed interest in perovskite-type catalysts for environmental applications.

  18. Reformed Confessions and Scholasticism. Diversity and Harmony

    Directory of Open Access Journals (Sweden)

    Beck Andreas J.

    2016-12-01

    Full Text Available This paper discusses the complex relationship of Reformed confessions and Reformed orthodox scholasticism. It is argued that Reformed confessions differ in genre and method from Reformed scholastic works, although such differences between confessional and scholastic language should not be mistaken for representing different doctrines that are no longer in harmony with each other. What is more, it is precisely the scholastic background and training of the authors of such confessions that enabled them to place their confessional writings in the broader catholic tradition of the Christian church and to include patristic and medieval theological insights. Thus proper attention to their scholastic background helps to see that at least in some confessions the doctrine of predestination, for instance, is not as ‘rigid’ as one might think at first sight. In order to demonstrate that the doctrine of the Reformed confessions was much in line with the scholastic theology of Reformed orthodoxy, this paper discusses, after having explained the terms ‘Reformed orthodoxy’ and ‘scholasticism’, the early Reformed scholastic theologians Beza, Zanchi, and Ursinus, who also have written confessional texts. The paper also includes a more detailed discussion of the Belgic Confession and the scholastic background of the Canons of Dordt and the Westminster Confession, thereby focusing on the doctrines of God, providence, and predestination.

    Facial harmony is one of the main goals of orthodontic treatment, and it is not always correlated with the attainment of cephalometric objectives. The purpose of this study was to evaluate two groups of subjects presenting a clinically balanced soft tissue profile using cephalometric radiographs. Thirty lateral cephalometric radiographs of white females, divided in two groups, one with excellent facial profile (Group 1), and the other with good facial profile (Group 2) were used. Student's t-test (P SnV-Pog and between AB horizontal and SnV-Pog'. Group 2 showed higher mean values than group 1 for ANB (p = 0.002), AB horizontal (p SnV-Pog (p = 0.003). The higher the SnV-Pog value, the lower the 1.NB value, no matter what group was evaluated. For each 1 mm increase in SnV-Pog, a 0.61 degree decrease could be expected in 1.NB (p = 0.003). The higher the SnV-Pog value, the lower the AB horizontal value, although group 2 presented greater AB horizontal values. For each 1 mm increase in SnV-Pog, a 0.24 mm decrease could be expected in AB horizontal (p = 0.019). We concluded that women with good facial profile do not necessarily present the same cephalometric values, and facial analysis should be the main reference in planning orthodontic treatments and should be considered together with cephalometric analysis in an individualized way.

  20. Toward harmonious development of the uranium market

    International Nuclear Information System (INIS)

    Suzuki, Y.

    1984-01-01

    Japan's economy is in a period of low growth, and growth in electricity demand has decreased substantially. Nuclear power remains the mainstay of Japan's energy policy, even though targets have been lowered. Japanese utilities attempted to procure as much uranium as possible for the long-term operation of their plants soon after the nuclear development plan was set in 1972. By 1975 they had secured around 80% of the cumulative uranium requirements up to the year 1990 through long-term contracts. Since then the scale of the nuclear power development program has shrunk to about one third of what it was in 1975. As a result, the quantity of uranium under long-term contracts far exceeds the actual demand. The existing contracted quantity is sufficient to cover total demand well into the late 1990s. Appropriate levels of stockpiling have yet to be determined. Security of supply can be assured without stockpiling if utilities diversify their sources of supply. The uranium market will develop harmoniously if producers and suppliers work towards securing flexibility for demand fluctuations, preventing government interference, and exchanging the information needed for precise uranium demand forecasting.

    Full Text Available Harmony search algorithm (HS is a new metaheuristic algorithm which is inspired by a process involving musical improvisation. HS is a stochastic optimization technique that is similar to genetic algorithms (GAs and particle swarm optimizers (PSOs. It has been widely applied in order to solve many complex optimization problems, including continuous and discrete problems, such as structure design, and function optimization. A cooperative harmony search algorithm (CHS is developed in this paper, with cooperative behavior being employed as a significant improvement to the performance of the original algorithm. Standard HS just uses one harmony memory and all the variables of the object function are improvised within the harmony memory, while the proposed algorithm CHS uses multiple harmony memories, so that each harmony memory can optimize different components of the solution vector. The CHS was then applied to function optimization problems. The results of the experiment show that CHS is capable of finding better solutions when compared to HS and a number of other algorithms, especially in high-dimensional problems.

    Full Text Available Facial Harmony is one of the main goals of orthodontic treatment, and it is not always correlated with the attainment of cephalometric objectives. The purpose of this study was to evaluate two groups of subjects presenting a clinically balanced soft tissue profile using cephalometric radiographs. Thirty lateral cephalometric radiographs of white females, divided in two groups, one with excellent facial profile (Group 1, and the other with good facial profile (Group 2 were used. Student's t-test (P?< .05 was used to compare the cephalometric parameters of the 2 groups. Linear regression analysis was also performed between 1.NB and SnV-Pog and between AB horizontal and SnV-Pog'. Group 2 showed higher mean values than group 1 for ANB (p = 0.002, AB horizontal (p < 0.001, 1.NB (p < 0.001, and a lower mean value for SnV-Pog (p = 0.003. The higher the SnV-Pog value, the lower the 1.NB value, no matter what group was evaluated. For each 1 mm increase in SnV-Pog, a 0.61º decrease could be expected in 1.NB (p = 0.003. The higher the SnV-Pog value, the lower the AB horizontal value, although group 2 presented greater AB horizontal values. For each 1 mm increase in SnV-Pog, a 0.24 mm decrease could be expected in AB horizontal (p = 0.019. We concluded that women with good facial profile do not necessarily present the same cephalometric values, and facial analysis should be the main reference in planning orthodontic treatments and should be considered together with cephalometric analysis in an individualized way.

    The research aims to analyze an event model of Culture and Tourism International Camp (Cultic) from two aspects, harmonious culture and sustainable tourism. Currently, Indonesian government promotes village tourism by involving more villagers to achieve village independence in its development. The program has faced various obstacles, such as the eroded local cultures due to the development of a massive and money-oriented tourism with less attention on the environmental damage. One of the offered programs is a green tourism model for an event named Culture and Tourism International Camps - Cultic. The research is conducted in several stages. The first stage is the development of model based on the theoretical study. The second stage is the implementation of the model with 85 participants. The third stage is the evaluation of the model through harmonious culture and sustainable tourism approaches. The data is collected through a direct observation and a questionnaire. The result of qualitative analysis indicates that the developed event model supports the harmonious culture, especially the natural environment. Whereas, the result of quantitative analysis indicates that the participants enjoy the activities, such as green food, material natural, waste management, and ecosystem. Another finding is that the community strongly supports the concept of sustainable tourism.

    Additional safe and effective therapies for type 2 diabetes are needed, especially ones that do not cause weight gain and have a low risk of hypoglycaemia. The present study evaluated albiglutide as monotherapy. In this placebo-controlled study, 309 patients (aged ≥ 18 years) with type 2 diabetes inadequately controlled by diet and exercise and who were not using a glucose-lowering agent (HbA1c 7.0-10.0% [53.00-85.79 mmol/mol], body mass index 20-45 kg/m(2), and fasting C-peptide ≥ 0.26 nmol/l) were randomised (1:1:1 on a fixed randomisation schedule using an interactive voice response system) to receive once-weekly albiglutide 30 mg (n = 102) or 50 mg (n = 102) or matching placebo (n = 105). The study treatments were blinded to both patients and study personnel. All study data were collected at individual patient clinic visits. The primary efficacy endpoint was change in HbA1c from baseline to week 52. The primary analysis was applied to the intent-to-treat population. Additional efficacy and safety endpoints were assessed. At week 52, both albiglutide 30 mg and 50 mg were superior to placebo in reducing HbA1c. The least-squares means treatment difference from placebo was -0.84% (95% CI -1.11%, -0.58%; p < 0.0001) with albiglutide 30 mg and -1.04% (-1.31%, -0.77%; p < 0.0001) with albiglutide 50 mg. Injection-site reactions were reported more frequently with albiglutide (30 mg: 17.8%; 50 mg: 22.2%) than with placebo (9.9%). Other commonly reported adverse events included nausea, diarrhoea, vomiting and hypoglycaemia; the incidences of these were generally similar across treatment groups. Albiglutide is safe and effective as monotherapy and significantly lowered HbA1c levels over 52 weeks, did not cause weight gain, and had good gastrointestinal tolerability and a low rate of hypoglycaemia compared with placebo.

    Highlights: ► Exploit of DHS algorithm in LP optimization reveals its flexibility, robustness and reliability. ► Upshot of our experiments with DHS shows that the search approach to optimal LP is quickly. ► On the average, the final band width of DHS fitness values is narrow relative to HS and GHS. -- Abstract: The objective of this work is to develop a core loading optimization technique using differential harmony search algorithm in the context of obtaining an optimal configuration of fuel assemblies in pressurized water reactors. To implement and evaluate the proposed technique, differential harmony search nodal expansion package for 2-D geometry, DHSNEP-2D, is developed. The package includes two modules; in the first modules differential harmony search (DHS) is implemented and nodal expansion code which solves two dimensional-multi group neutron diffusion equations using fourth degree flux expansion with one node per a fuel assembly is in the second module. For evaluation of DHS algorithm, classical harmony search (HS) and global-best harmony search (GHS) algorithms are also included in DHSNEP-2D in order to compare the outcome of techniques together. For this purpose, two PWR test cases have been investigated to demonstrate the DHS algorithm capability in obtaining near optimal loading pattern. Results show that the convergence rate of DHS and execution times are quite promising and also is reliable for the fuel management operation. Moreover, numerical results show the good performance of DHS relative to other competitive algorithms such as genetic algorithm (GA), classical harmony search (HS) and global-best harmony search (GHS) algorithms

    The relationship between economic development and environment and the evolution characteristics of spatial pattern in Hexi Corridor of Northwest China were analyzed based on Landsat images in 1985, 1995, 2000 and 2011 with twenty counties in Hexi Corridor chosen as the basic research units. The ecological economic harmony during 1985-2011 was estimated according to ESV (ecosystem services value) and EEH (ecological and economic harmony) index with the ecosystem services value estimation methods. The results showed that the land type of the study area dramatically changed during the study period, the grassland decreased badly, and the construction land and cultivated land increased quickly. The ESV showed an overall downward trend, especially in the Shiyang River basin and the middle of Heihe River. The ESV in the Shule River basin in this period. After 2000, the economic growth speeded up visibly in the study area. The economic development concentrated in the resource-based cities and regional central cities, and declined from the center of corridor to the both sides. The ecological-economic relation in Hexi Corridor experienced a transformation of "preliminary deterioration--further deterioration--low grade coordination". The EEH had large changes in the Shiyang River basin and the middle of Heihe River, which experienced a transformation of "conflict--more conflicts--less conflicts", however, there was little change in Shule River basin. The development mode and the comprehensive reclamation of Shiyang River basin and Heihe River basin had a significant influence on the regional ecological and economic harmony.

    2017-01-01

    A new topology optimization scheme based on a Harmony search (HS) as a metaheuristic method was proposed and applied to static stiffness topology optimization problems. To apply the HS to topology optimization, the variables in HS were transformed to those in topology optimization. Compliance was used as an objective function, and harmony memory was defined as the set of the optimized topology. Also, a parametric study for Harmony memory considering rate (HMCR), Pitch adjusting rate (PAR), and Bandwidth (BW) was performed to find the appropriate range for topology optimization. Various techniques were employed such as a filtering scheme, simple average scheme and harmony rate. To provide a robust optimized topology, the concept of the harmony rate update rule was also implemented. Numerical examples are provided to verify the effectiveness of the HS by comparing the optimal layouts of the HS with those of Bidirectional evolutionary structural optimization (BESO) and Artificial bee colony algorithm (ABCA). The following conclu- sions could be made: (1) The proposed topology scheme is very effective for static stiffness topology optimization problems in terms of stability, robustness and convergence rate. (2) The suggested method provides a symmetric optimized topology despite the fact that the HS is a stochastic method like the ABCA. (3) The proposed scheme is applicable and practical in manufacturing since it produces a solid-void design of the optimized topology. (4) The suggested method appears to be very effective for large scale problems like topology optimization.

    Although empirical research on aesthetics has had some success in explaining the average preferences of groups of observers, relatively little is known about individual differences in preference, and especially about how such differences might covary across different domains. In this study, we identified a new factor underlying aesthetic response-preference for harmonious stimuli-and examined how it varies over four domains (color, shape, spatial location, and music) across individuals with different levels of training in art and music. We found that individual preferences for harmony are strongly correlated across all four dimensions tested and decrease consistently with training in the relevant aesthetic domains. Confirmatory factor analysis revealed that cross-domain preference for harmony is well-represented as a single, unified factor, with effects separate from those of training and of common personality measures.

    Highlights: ► The classical and improved harmony search algorithms are introduced. ► The advantage of IHS is demonstrated in Shekel's Foxholes. ► The CHS and IHS are compared with other Heuristic algorithms. ► The adaptive improved harmony search is applied for two cases. ► Two cases of WWER core are optimized in BOC FA pattern. - Abstract: The efficient operation and fuel management of PWRs are of utmost importance. Core performance analysis constitutes an essential phase in core fuel management optimization. Finding an optimum core arrangement for loading of fuel assemblies, FAs, in a nuclear core is a complex problem. In this paper, application of classical harmony search (HS) and adaptive improved harmony search (IHS) in loading pattern (LP) design, for pressurized water reactors, is described. In this analysis, finding the best core pattern, which attains maximum multiplication factor, k eff , by considering maximum allowable power picking factors (PPF) is the main objective. Therefore a HS based, LP optimization code is prepared and CITATION code which is a neutronic calculation code, applied to obtain effective multiplication factor, neutron fluxes and power density in desired cores. Using adaptive improved harmony search and neutronic code, generated LP optimization code, could be applicable for PWRs core with many numbers of FAs. In this work, at first step, HS and IHS efficiencies are compared with some other heuristic algorithms in Shekel's Foxholes problem and capability of the adaptive improved harmony search is demonstrated. Results show, efficient application of IHS. At second step, two WWER cases are studied and then IHS proffered improved core patterns with regard to mentioned objective functions.

    2017-12-01

    HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multi-purpose SURFEX surface model. It is developed for high resolution (1-3 km) weather forecasting and applied in a number of regions in Europe and the Mediterranean. A version of HARMONIE-AROME is also under development for regional climate modelling. Here we run HARMONIE-AROME for a domain over Greenland that includes a significant portion of the Greenland ice sheet. The model output reproduces temperature, wind speed and direction and relative humidity over the ice sheet well when compared with the observations from PROMICE automatic weather stations (AWS) operated within the model domain on the ice sheet (mean temperature bias 1.31 ± 3.6 K) but we identified a much lower bias (-0.16 ± 2.3 K) at PROMICE sites on days where melt does not occur at the ice sheet surface and is thus an artefact of the simplified surface scheme over glaciers in the existing HARMONIE-AROME operational set-up. The bias in summer time temperature also affects wind speed and direction as the dominant katabatic winds are caused by the cold ice surface and slope gradient. By setting an upper threshold to the surface temperature of the ice surface within SURFEX we show that the weather forecast error over the Greenland ice sheet can be reduced in summer when glacier ice is exposed. This improvement will facilitate accurate ice melt and run-off computations, important both for ice surface mass budget estimation and for commercial applications such as hydro-power forecasting. Furthermore, the HCLIM regional climate model derived from HARMONIE-AROME will need to accurately account for glacier surface processes in these regions in order to be used to accurately compute the surface mass budget of ice sheets and glaciers, a key goal of regional climate modelling studies in Greenland.

    The brilliant German mathematician Johannes Kepler (1571-1630), one of the founders of modern astronomy, revolutionized the Copernican heliocentric theory of the universe with his three laws of motion: that the planets move not in circular but elliptical orbits, that their speed is greatest when nearest the sun, and that the sun and planets form an integrated system. This volume contains two of his most important works: The Epitome of Copernican Astronomy (books 4 and 5 of which are translated here) is a textbook of Copernican science, remarkable for the prominence given to physical astronomy and for the extension to the Jovian system of the laws recently discovered to regulate the motions of the Planets. Harmonies of the World (book 5 of which is translated here) expounds an elaborate system of celestial harmonies depending on the varying velocities of the planets.

    2012-01-01

    Full Text Available This paper describes a new variant of harmony search algorithm which is inspired by a well-known item “elite decision making.” In the new algorithm, the good information captured in the current global best and the second best solutions can be well utilized to generate new solutions, following some probability rule. The generated new solution vector replaces the worst solution in the solution set, only if its fitness is better than that of the worst solution. The generating and updating steps and repeated until the near-optimal solution vector is obtained. Extensive computational comparisons are carried out by employing various standard benchmark optimization problems, including continuous design variables and integer variables minimization problems from the literature. The computational results show that the proposed new algorithm is competitive in finding solutions with the state-of-the-art harmony search variants.

Although it could not be denied that there are other facts found in this study by interviewing people at the grass roots.  These people gave different response; their responses tend to be negative which may lead to a conflict of identity between local people and migrants.

  6. An improved harmony search algorithm for power economic load dispatch

    International Nuclear Information System (INIS)

    Santos Coelho, Leandro dos; Mariani, Viviana Cocco

    2009-01-01

    A meta-heuristic algorithm called harmony search (HS), mimicking the improvisation process of music players, has been recently developed. The HS algorithm has been successful in several optimization problems. The HS algorithm does not require derivative information and uses stochastic random search instead of a gradient search. In addition, the HS algorithm is simple in concept, few in parameters, and easy in implementation. This paper presents an improved harmony search (IHS) algorithm based on exponential distribution for solving economic dispatch problems. A 13-unit test system with incremental fuel cost function taking into account the valve-point loading effects is used to illustrate the effectiveness of the proposed IHS method. Numerical results show that the IHS method has good convergence property. Furthermore, the generation costs of the IHS method are lower than those of the classical HS and other optimization algorithms reported in recent literature.

    2013-01-01

    Full Text Available In this paper, a multilevel thresholding (MT algorithm based on the harmony search algorithm (HSA is introduced. HSA is an evolutionary method which is inspired in musicians improvising new harmonies while playing. Different to other evolutionary algorithms, HSA exhibits interesting search capabilities still keeping a low computational overhead. The proposed algorithm encodes random samples from a feasible search space inside the image histogram as candidate solutions, whereas their quality is evaluated considering the objective functions that are employed by the Otsu’s or Kapur’s methods. Guided by these objective values, the set of candidate solutions are evolved through the HSA operators until an optimal solution is found. Experimental results demonstrate the high performance of the proposed method for the segmentation of digital images.

    The development of environmental quality criteria is a major global industry; it occupies the time and pays the salaries of professionals in a variety of fields. Scientists provide the data to support or oppose these criteria; lawyers provide the framework for or argue against their promulgation; administrators try to make criteria work or seek loopholes; politicians favor them (or say they do); environmentalists alternately promote and denounce them; and members of the general public hope the criteria will protect the environment but not adversely affect their own jobs or lifestyles. Is all this activity achieving its objective of improving environmental quality? Are we sure what that objective is? The author believes that the answer to both questions is a clear no. The purpose of this article is to explain this position, to suggest possible remedies, and to urge their immediate implementation

    Automotive painting program in the process of painting the car body by using robot power, making efficiency in the production system. Production system will be more efficient if pay attention to scheduling of car order which will be done by considering painting body shape of car. Flow shop scheduling is a scheduling model in which the job-job to be processed entirely flows in the same product direction / path. Scheduling problems often arise if there are n jobs to be processed on the machine, which must be specified which must be done first and how to allocate jobs on the machine to obtain a scheduled production process. Harmony Search Algorithm is a metaheuristic optimization algorithm based on music. The algorithm is inspired by observations that lead to music in search of perfect harmony. This musical harmony is in line to find optimal in the optimization process. Based on the tests that have been done, obtained the optimal car sequence with minimum makespan value.

    Highlights: ► Numerical results reveal that the HS method is reliable. ► The great advantage of HS is significant gain in computational cost. ► On the average, the final band width of search fitness values is narrow. ► Our experiments show that the search approaches the optimal value fast. - Abstract: In this paper a core reloading technique using Harmony Search, HS, is presented in the context of finding an optimal configuration of fuel assemblies, FA, in pressurized water reactors. To implement and evaluate the proposed technique a Harmony Search along Nodal Expansion Code for 2-D geometry, HSNEC2D, is developed to obtain nearly optimal arrangement of fuel assemblies in PWR cores. This code consists of two sections including Harmony Search algorithm and Nodal Expansion modules using fourth degree flux expansion which solves two dimensional-multi group diffusion equations with one node per fuel assembly. Two optimization test problems are investigated to demonstrate the HS algorithm capability in converging to near optimal loading pattern in the fuel management field and other subjects. Results, convergence rate and reliability of the method are quite promising and show the HS algorithm performs very well and is comparable to other competitive algorithms such as Genetic Algorithm and Particle Swarm Intelligence. Furthermore, implementation of nodal expansion technique along HS causes considerable reduction of computational time to process and analysis optimization in the core fuel management problems

    Full Text Available HARMONIE-AROME is a convection-permitting non-hydrostatic model that includes the multi-purpose SURFEX surface model. It is developed for high resolution (1–3 km weather forecasting and applied in a number of regions in Europe and the Mediterranean. A version of HARMONIE-AROME is also under development for regional climate modelling. Here we run HARMONIE-AROME for a domain over Greenland that includes a significant portion of the Greenland ice sheet. The model output reproduces temperature, wind speed and direction and relative humidity over the ice sheet well when compared with the observations from PROMICE automatic weather stations (AWS operated within the model domain on the ice sheet (mean temperature bias 1.31 ± 3.6 K but we identified a much lower bias (−0.16 ± 2.3 K at PROMICE sites on days where melt does not occur at the ice sheet surface and is thus an artefact of the simplified surface scheme over glaciers in the existing HARMONIE-AROME operational set-up. The bias in summer time temperature also affects wind speed and direction as the dominant katabatic winds are caused by the cold ice surface and slope gradient. By setting an upper threshold to the surface temperature of the ice surface within SURFEX we show that the weather forecast error over the Greenland ice sheet can be reduced in summer when glacier ice is exposed. This improvement will facilitate accurate ice melt and run-off computations, important both for ice surface mass budget estimation and for commercial applications such as hydro-power forecasting. Furthermore, the HCLIM regional climate model derived from HARMONIE-AROME will need to accurately account for glacier surface processes in these regions in order to be used to accurately compute the surface mass budget of ice sheets and glaciers, a key goal of regional climate modelling studies in Greenland.

    Full Text Available Individuals of many species across the animal kingdom are found to be less plastic than expected, even in behavioral traits. The existence of consistent behavioral differences between individuals, termed personality differences, is puzzling, since plastic behavior is considered ideal to enable animals to adaptively respond to changes in environmental conditions. In order to elucidate which mechanisms are important for the evolution of personality differences, it is crucial to understand which aspects of the environment are important for the development of personality differences. Here, we tested whether physical or social aspects of the environment during development influence individual differentiation (mean level of behavior using the jumping spider Marpissa muscosa. Furthermore, we assessed whether those behaviors were repeatable, i.e. whether personalities existed. We applied a split-brood design and raised spider siblings in three different environments: a deprived environment with no enrichment, a socially and a physically enriched environment. We focused on exploratory behavior and repeatedly assessed individual behavior in a novel environment and a novel object test. Results show that the environment during development influenced spiders’ exploratory tendencies: spiders raised in enriched environments tended to be more exploratory. Most investigated behaviors were repeatable (i.e. personalities existed across all individuals tested, whereas only few behaviors were also repeatable across individuals that had experienced the same environmental condition. Taken together, our results indicate that external stimuli can influence the development of one aspect of personality, the inter-individual variation (mean level of behavior, in a jumping spider. We also found family by environment interactions on behavioral traits potentially suggesting genetic variation in developmental plasticity.

    We completed and published two papers in the Astrophysical Journal based on research from grant. In the first paper we analyzed nine X-ray-bright Virgo early-type galaxies observed by both ASCA and ROSAT. Through spatially resolved spectroscopy, we determined the radial temperature profiles and abundances of Mg, Si, and Fe for six galaxies. The temperature profiles are consistent with isothermal temperatures outside of cooler regions at the galaxies' centers. We present new evidence for iron abundance gradients in NGC 4472 and NGC 4649 and confirm the previous results on NGC 4636. Mg and Si abundance gradients on average are flatter than those of iron and correspond to an underabundance of α-process elements at high Fe values, while at low iron the element ratios favor enrichment by Type II supernovae (SNe). We explain the observed trend using the metallicity dependence of SN Ia metal production and present constraints on the available theoretical modeling for low-metallicity inhibition of SNe Ia.

  16. Environmental consequences of hydroelectric development: the role of facility size and type

    1992-01-01

    The development of hydroelectric power throughout the world is receiving renewed attention as the economic, political, and environmental costs of conventional energy production rise. There is currently a perception that hydroelectricity has environmental and economic advantages over electricity produced by conventional energy technologies, but there is a paucity of information about the environmental impacts of hydroelectric facilities as a function of size and type. We characterize the environmental impacts of hydroelectric developments and quantify these impacts as a function of the size and type of project. Several unexpected conclusions arise from our analysis. For most hydroelectric facilities, size, as measured by installed capacity, is not necessarily a good indicator or the severity of environmental costs. For impacts such as land flooded and evaporative water lost, smaller facilities cause greater environmental disruptions per unit of energy produced than do larger facilities. (Author)

  18. A Novel Type of Environmentally Friendly Slurry Coatings

    2015-01-01

    A variety of commercial slurries are available to aluminize the surfaces of nickel-based superalloys; however, they have three main disadvantages. First, the phosphates and chromates or halides used as binders or to activate the diffusion species are environmentally harmful and toxic; second, the slurry coatings can only produce high-aluminum-activity coatings which form precipitate-rich coatings that are detrimental to adherence. Finally, these coatings are limited to the incorporation of aluminum and silicon, whereas the co-deposition of other elements such as chromium or cobalt has not been achieved so far. In this work, the limitations of slurry coatings have been overcome by carefully designing the powder composition and controlling the process to produce co-deposition coatings with chromium, cobalt, or nickel by using nontoxic water-based slurries. This also opens an effective way to control Al activity and to produce low-activity aluminized coatings for the first time when using the slurry technique. These results expand the application range of slurry coatings so they can also be applied under ambient atmosphere, making it possible to fully coat aero engine pieces or large-scale industrial components, providing all properties that are usually only achieved by using more complex and expensive methods such as chemical vapor deposition. Furthermore, these new coatings offer unique advantages that can be very favorable especially as a repairing technique.

    This paper presents a harmony search based parallel optimization algorithm to minimize voltage deviations in three phase unbalanced electrical distribution systems and to maximize active power outputs of distributed energy resources (DR). The main contribution is to reduce the adverse impacts on voltage profile during a day as photovoltaics (PVs) output or electrical vehicles (EVs) charging changes throughout a day. The IEEE 123- bus distribution test system is modified by adding DRs and EVs under different load profiles. The simulation results show that by using parallel computing techniques, heuristic methods may be used as an alternative optimization tool in electrical power distribution systems operation.

    Full Text Available Investment decision-making based on aspects of sustainability is gaining importance among organizations around the globe. In this context, there is a need for quality investment decisions, which require sufficient knowledge among organizational managers about managing sustainability information to achieve environmental objectives that meet stakeholder expectations. This has led to the emergence of organizational performance measuring tools such as the Sustainability Balanced Scorecard, which integrates the environmental perspective into the traditional Balanced Scorecard. Using experimental research method, the objective of this study is to investigate the indirect effect of Eco-efficiency knowledge and Sustainability Balanced Scorecard knowledge as mediators influencing the relationship between Sustainability Balanced Scorecard types and their impact on environmental investment decision-making. Findings of the current research are based on 60 respondents who were randomly assigned to one of the following two types of Sustainability Balanced Scorecard architecture: (1 environmental data embedded within the traditional Balanced Scorecard perspectives; and (2 standalone environmental data as an additional fifth perspective along with the traditional Balanced Scorecard architecture. The traditional Balanced Scorecard without any information on environmental perspective is included in the experiment as the control condition. The findings indicate that the combined effect of eco-efficiency knowledge and Sustainability Balanced Scorecard knowledge has a significant positive influence on the relationship between the Balanced Scorecard type versus Sustainability Balanced Scorecard type and environmental investment decision-making.

    This study classifies urban environments into types characterized by different exposure to environmental risk factors measured by general sense of discomfort and Heart Rate Variability (HRV). We hypothesize that a set of environmental factors (micro-climatic, CO, noise and individual heart rate) that were measured simultaneously in random locations can provide a better understanding of the distribution of human exposure to environmental loads throughout the urban space than results calculated based on measurements from close fixed stations. We measured micro-climatic and thermal load, CO and noise, individual Heart Rate, Subjective Social Load and Sense of Discomfort (SD) were tested by questionnaire survey. The results demonstrate significant differences in exposure to environmental factors among 8 types of urban environments. It appears that noise and social load are the more significant environmental factors to enhance health risks and general sense of discomfort. Copyright © 2015 Elsevier Ltd. All rights reserved.

  4. LEARNING NONADJACENT DEPENDENCIES IN PHONOLOGY: TRANSPARENT VOWELS IN VOWEL HARMONY.

    Science.gov (United States)

    Finley, Sara

    2015-03-01

    Nonadjacent dependencies are an important part of the structure of language. While the majority of syntactic and phonological processes occur at a local domain, there are several processes that appear to apply at a distance, posing a challenge for theories of linguistic structure. This article addresses one of the most common nonadjacent phenomena in phonology: transparent vowels in vowel harmony. Vowel harmony occurs when adjacent vowels are required to share the same phonological feature value (e.g. V +F C V +F ). However, transparent vowels create a second-order nonadjacent pattern because agreement between two vowels can 'skip' the transparent neutral vowel in addition to consonants (e.g. V +F C V T -F C V +F ). Adults are shown to display initial learning biases against second-order nonadjacency in experiments that use an artificial grammar learning paradigm. Experiments 1-3 show that adult learners fail to learn the second-order long-distance dependency created by the transparent vowel (as compared to a control condition). In experiments 4-5, training in terms of overall exposure as well as the frequency of relevant transparent items was increased. With adequate exposure, learners reliably generalize to novel words containing transparent vowels. The experiments suggest that learners are sensitive to the structure of phonological representations, even when learning occurs at a relatively rapid pace.

    Full Text Available The religious tolerance and harmony is something necessary to develop due to the need of global security and peace today. For this purpose, all religions have to be fairly “tolerant” to others. Islam as a revealed religion, whatever its motive, is often perceived and accused as the religion of intolerance and violence. Some political and ideological questions, for example raised to this context: "Can Islamic faith tolerate other faiths, religions or groups?”, What’s actually the Islamic teachings on tolerance and peace or harmony?” and the likes. This article attempts to unpack and elaborate of how far at Qur’an –as the first and primary source of Islam– has a teaching on tolerance and peace. Using a hermeneutical approach the writer understands and analyses what is actually taught by al Qur'an on the concepts and practices of the tolerance. Based on the analysis, he highlights any conclusions of which al-Qur’an (Islam teaches the followers to respect and implement the doctrine of tolerance and peace. The Muslim world is imperatively to tolerate others, or respect the differences for strengthening the world security and peaceful life amongst nationwide.

    Full Text Available The authors consider that the current global crisis has an ecolonomic character in the sensethat it negatively affects all parties from all common living beginnig with the people and their families,communities and business organizations, state institutions and continuing with ecology of the living world.Such a disorder of “comeostasis”at the level of the “whole common living”is the result of excesses anddeficits of human and institutional behavior which, proplonged in time, beyond the “critical mass, aredangerous for the “health of whole common living”.The holistic researches highlight that the current ecolonomic crisis is the result of the “fall of man”,mainly caused by the excesses of freedom and deficits of responsability. These cause a pathological work, notalways a vocation type, a disproportionate evolution of society, knowledge “of up”and the morality of its use “indow”, a promotion of science beyond humanism, an increase of markets without morality, an overconsumption“uncontrolled by biology and moral” for several million of people, at the same time with a subconsumption thatjeopardize the survival for few billion of people.These opposites of our evolution did not fall from heaven, they are not “gifts from God”, of unfavorablenature. They are the result of some human and institutional behaviors that are based on the opposite education.Therefore, we need to re-spiritualize education based on the principle of harmony, to re-integrate inthis invention of human society love, true knowledge and faith in the certainty of hope.Education, in terms of harmony, will integrate all the values of meaning, such as “maturing freedom inresponsability, humanity, solidarity and social communion”, is vital for teaching people to live their own life inTruth, Goodness and Beauty.A new education means, at universal scale, the transition to the ecolonomic society in which the winwinpeinciple becomes the golden rule of life

    Full Text Available Polyoxyethylene type nonionic surfactants such as alkylphenol ethoxylates(APEOs, alcohol ethoxylates(AEOs and alkylamine ethoxylates(ANEOs are typical pesticide adjuvants. Their unique environmental behavior characteristic is reflected in the parameters describing the fate e.g.distribution coefficient, adsorption to soil, degradation and effects of these substances. The major environmental problem related to these compounds is their part metabolites' relatively higher environmental risk. In views of their chemical structure, this paper outlined present knowledge on occurrence, fate and environment effect of the three adjuvants:AEOs, ANEOs and APEOs. The adsorption behaviour of ANEOs in contrast to AEOs was particularly variable and matrix dependent due to the ability of the compound to ionise at environmentally relevant pH. Probably because the compounds exceeded high soil adsorption and were easily degradable which were reflected in the low environmental concentrations generally found in monitoring studies.

    Full Text Available This paper follows up on some of the phonetic assumptions underlying earlier discussions in the phonological literature of the vowel reduction in Brazilian Portuguese such as Crosswhite (2004 and Flemming (2004, among others. We investigated various reflexes of prosodic prominence across four positions: tonic, pretonic, posttonic, and word-final. The height of the low vowel /a/ in these contexts was also determined. We found that while duration readily distinguished among the first three positions (tonic > pretonic > posttonic, it failed to differentiate posttonic from final. Intensity was a better discriminator across all four positions. We also documented a height harmony between pretonic mid vowels and the following tonic resulting in a seven-vowel pretonic inventory that parallels the tonic*. The implications of these findings for metrical prominence and dispersion accounts of vowel reduction are considered.

    This study puts forward a new concept, "population urbanization level forecast - driving factor analysis - urban spatial planning analysis" for achieving efficient and intensive development of urbanization considering human-land harmony. We analyzed big data for national economic and social development, studied the development trends of population urbanization and its influencing factors using the grey system model in Chengmai county of Hainan province, China. In turn, we calculated the population of Chengmai coming years based on the forecasting urbanization rate and the corresponding amount of urban construction land, and evaluated the urban spatial planning with GIS spatial analysis method in the study area. The result shows that the proposed concept is feasible for evaluation of urban spatial planning, and is meaningful for guiding the rational distribution of urban space, controlling the scale of development, improving the quality of urbanization and thus promoting highly-efficient and intensive use of limited land resource.

    The paper is a follow up of the work presented in last year's Optics and Music session on the perception of coherence between low frequency power modulated light and periodical acoustic stimuli. The composition of chords and harmonies from power modulated light sources and their effect as stand-alone stimulus and in conjunction with the equivalent acoustic signal is discussed. Of special interest here is the modulation near perceptible flicker frequency. The substitution of acoustical chord components by their optical counterpart and vice versa is investigated. Further, concepts of a training application for trombone players and other instrumentalists are presented: since the mean slide of the trombone does not have fixed positions, the note must be found and two players might influence each other. The possibility of helping them to synchronize by optical stimuli derived from their playing is investigated. Beside possible applications in emotional reinforcing multimedia oriented entertainment and training support for musicians, again implications for occupational medicine are discussed.

    Full Text Available This paper presents a kernel fuzzy clustering with a novel differential harmony search algorithm to coordinate with the diversion scheduling scheme classification. First, we employed a self-adaptive solution generation strategy and differential evolution-based population update strategy to improve the classical harmony search. Second, we applied the differential harmony search algorithm to the kernel fuzzy clustering to help the clustering method obtain better solutions. Finally, the combination of the kernel fuzzy clustering and the differential harmony search is applied for water diversion scheduling in East Lake. A comparison of the proposed method with other methods has been carried out. The results show that the kernel clustering with the differential harmony search algorithm has good performance to cooperate with the water diversion scheduling problems.

    Having the ability to scan the entire country for potential "hotspots" with increased risk of developing chronic diseases due to various environmental, demographic, and genetic susceptibility factors may inform risk management decisions and enable better environmental public health policies. Develop an approach for community-level risk screening focused on identifying potential genetic susceptibility hotpots. Our approach combines analyses of phenotype-genotype data, genetic prevalence of single nucleotide polymorphisms, and census/geographic information to estimate census tract-level population attributable risks among various ethnicities and total population for the state of California. We estimate that the rs13266634 single nucleotide polymorphism, a type 2 diabetes susceptibility genotype, has a genetic prevalence of 56.3%, 47.4% and 37.0% in Mexican Mestizo, Caucasian, and Asian populations. Looking at the top quintile for total population attributable risk, 16 California counties have greater than 25% of their population living in hotspots of genetic susceptibility for developing type 2 diabetes due to this single genotypic susceptibility factor. This study identified counties in California where large portions of the population may bear additional type 2 diabetes risk due to increased genetic prevalence of a susceptibility genotype. This type of screening can easily be extended to include information on environmental contaminants of interest and other related diseases, and potentially enables the rapid identification of potential environmental justice communities. Other potential uses of this approach include problem formulation in support of risk assessments, land use planning, and prioritization of site cleanup and remediation actions.

    Full Text Available This study aims to understand the religious elite view of pluralism and religious harmony in  Malang. The study was focused on the meaning of pluralism and religious harmony, efforts  and things that support and hinder the realization of religious harmony. Empirical research  data with qualitative-phenomenological approach was collected through interviews and documentation. The results show: first, the meaning of religious pluralism for the religious elites is very varied, which is the same as tolerance, mutual respect, the goal of all religions are the same, and recognize the fact that there are many religions in this world. Second, religiousharmony have meaning as a condition where there is no oppression and domination of one religion over other religions, awakening a deep awareness of diversity, respect for human rights, and the willingness to spread kindness and love for fellow human beings. Third, religious harmony can be achieved through internal efforts to strengthen the faith of each and build awareness to develop a positive attitude towards other religions. In external efforts to create harmony done through emancipatory dialogue and cooperation to resolve humanitarian issues. Fourth, positive attitude that supports the creation of harmony of religions is the willingness and awareness to understand each other and share experiences. Egoism, truth claims, fanaticism, and exclusivism is a negative attitude and expression recognized by the religious elite can interfere with the establishment of inter-religious harmony.

  20. The influences of harmony motives and implicit beliefs on conflict styles of the collectivist.

    Lim, Lena L

    2009-12-01

    The collectivist preference for nonconfrontational conflict styles is usually attributed to the influences of the Confucian value of harmony, which promotes tolerance of interpersonal transgression. Harmony has two distinct motives in collectivistic Asian societies (Leung, 1997 ): harmony enhancement is affective in nature and represents a genuine concern for relationship harmony, while disintegration avoidance is instrumental in nature and sees harmony maintenance as a means to other ends. Hence, as predicted, harmony enhancement is positively related to the use of integrating and compromising, while disintegration avoidance is positively related to the use of avoiding and obliging and is negatively related to the use of integrating during a conflict with a peer in a collectivistic society, Singapore. Besides examining this from a motivational perspective, the study also examines the role of implicit beliefs of personality on one's choice of conflict styles. The two implicit theories of personality refer to the two different assumptions the lay person has about the mutability of personal attributes; an entity theorist believes that personal attributes are fixed and nonmalleable qualities, while an incremental theorist sees personal attributes as qualities that can be developed and changed. Results reveal that incrementalist implicit beliefs also significantly predicted the use of integrating. Harmony enhancement represents a genuine concern for relationship harmony and involves feelings of closeness, unity, and trust. The finding that integrating is predicted by a harmony enhancement motivation suggests the importance of fostering collectivist values of interdependence and feelings of unity and trust so as to encourage the use of integrating to discuss the opposing views openly and constructively. The present study also underscores the benefit of learning an incremental theory to be open to the positive changes in others and work toward improving the relationship

    This study classifies urban environments into types characterized by different exposure to environmental risk factors measured by general sense of discomfort and Heart Rate Variability (HRV). We hypothesize that a set of environmental factors (micro-climatic, CO, noise and individual heart rate) that were measured simultaneously in random locations can provide a better understanding of the distribution of human exposure to environmental loads throughout the urban space than results calculated based on measurements from close fixed stations. We measured micro-climatic and thermal load, CO and noise, individual Heart Rate, Subjective Social Load and Sense of Discomfort (SD) were tested by questionnaire survey. The results demonstrate significant differences in exposure to environmental factors among 8 types of urban environments. It appears that noise and social load are the more significant environmental factors to enhance health risks and general sense of discomfort. - Highlights: • Indoor and outdoor environments were classified by exposure to health concern. • Measurements taken by people provide better knowledge than fixed stations. • Social stress and noise are more stressing factors than Thermal load and CO. • The most stressful places are crowded ones like markets etc. • Short visit in green spaces are effective in reducing levels of stress.

    Full Text Available Type 1 diabetes mellitus (T1DM is an autoimmune disease, where destruction of beta-cells causes insulin deficiency. The incidence of T1DM has increased in the last decades and cannot entirely be explained by genetic predisposition. Several environmental factors are suggested to promote T1DM, like early childhood enteroviral infections and nutritional factors, but the evidence is inconclusive. Prenatal and early life exposure to environmental pollutants like phthalates, bisphenol A, perfluorinated compounds, PCBs, dioxins, toxicants, and air pollutants can have negative effects on the developing immune system, resulting in asthma-like symptoms and increased susceptibility to childhood infections. In this review the associations between environmental chemical exposure and T1DM development is summarized. Although information on environmental chemicals as possible triggers for T1DM is sparse, we conclude that it is plausible that environmental chemicals can contribute to T1DM development via impaired pancreatic beta-cell and immune-cell functions and immunomodulation. Several environmental factors and chemicals could act together to trigger T1DM development in genetically susceptible individuals, possibly via hormonal or epigenetic alterations. Further observational T1DM cohort studies and animal exposure experiments are encouraged.

    In this article, the optimization of isolation system parameters via the harmony search (HS) optimization method is proposed for seismically isolated buildings subjected to both near-fault and far-fault earthquakes. To obtain optimum values of isolation system parameters, an optimization program was developed in Matlab/Simulink employing the HS algorithm. The objective was to obtain a set of isolation system parameters within a defined range that minimizes the acceleration response of a seismically isolated structure subjected to various earthquakes without exceeding a peak isolation system displacement limit. Several cases were investigated for different isolation system damping ratios and peak displacement limitations of seismic isolation devices. Time history analyses were repeated for the neighbouring parameters of optimum values and the results proved that the parameters determined via HS were true optima. The performance of the optimum isolation system was tested under a second set of earthquakes that was different from the first set used in the optimization process. The proposed optimization approach is applicable to linear isolation systems. Isolation systems composed of isolation elements that are inherently nonlinear are the subject of a future study. Investigation of the optimum isolation system parameters has been considered in parametric studies. However, obtaining the best performance of a seismic isolation system requires a true optimization by taking the possibility of both near-fault and far-fault earthquakes into account. HS optimization is proposed here as a viable solution to this problem.

  5. Economic Harmony: An Epistemic Theory of Economic Interactions

    2017-01-01

    Full Text Available We propose an epistemic theory of micro-economic interactions, termed Economic Harmony. In the theory, we modify the standard utility, by changing its argument from the player’s actual payoff, to the ratio between the player’s actual payoff and his or her aspired payoff. We show that the aforementioned minor epistemic modification of the concept of utility is quite powerful in generating plausible and successful predictions of experimental results, obtained in the standard ultimatum game, and the sequential common pool resource dilemma (CPR game. Notably, the cooperation and fairness observed in the studied games are accounted for without adding an other-regarding component in the players’ utility functions. For the standard ultimatum game, the theory predicts a division of φ and 1 − φ, for the proposer and responder, respectively, where φ is the famous Golden Ratio (≈0.618, most known for its aesthetically pleasing properties. We discuss possible extensions of the proposed theory to repeated and evolutionary ultimatum games.

We derive and compute the general relation of the power exponent of the degreedistribution with the entropy by using the Boltzmann-Gibbs entropy (BGS and the Tsallisnon-extensive entropy (Sq. It is found that the BGS decreases as d/r increases and thecurrent of the BGS along with hybrid ratio d/r or exponent γ of power-law is in agreementbetween numerical simulation and theoretical analysis. The relationship between the Sq andcharacteristic parameter q under different d/r is also given. And the Sq approaches to theBGS when q → 1. These results can provide a better understanding for evolutioncharacteristic in growing complex networks and further applications in networkengineering are of prospective potential.

    Full Text Available The advent of Islam in Tatar Sunda (West Java lent a new color to the culture that had previously existed there. The nature of Islam which was friendly to the local culture, made it easy to be accepted by the Sundanese people without bloodshed. The results are a variety of cultural rituals rooted in Sundanese culture yet rich with Islamic culture. Seren Taun Guru Bumi is one of the rituals of the Sundanese people deeply-rooted in the belief of Nyi Pohaci (Dewi Sri as the goddess of fertility. The involvement of the researcher in this ritual made the data a primary source which is the implementation of Seren Taun Guru Bumi in Sindang Barang Cultural Village, Bogor, West Java. This research shows that the ritual of Seren Taun Guru Bumi is a form of Islamic harmony with the Sundanese culture. Islamic culture assimilates in the frame of Sundanese traditions in Tatar Sunda, in which both are brought together in the ritual as a form of gratitude to God Almighty.

    Full Text Available By definition a natural park is a protected area designed to protect and conserve the natural environment in which the interaction between human activities and nature createda unique area, of significant environmental and cultural value and with great biodiversity.The main purpose of these natural parks is to maintain the harmony between humans and nature by protecting the biological diversity of the habitats and the environment. In recent years both the natural and anthropic areas of the Vişeu Basin have been greatly damaged by extreme hydric phenomenon caused by the chaotic deforestation of the area, increased precipitation, high pluvio-nival regime and the accentuated asymmetry of the basin itself. By developing certain hydrographical installations and conserving the protected areas a balance can be reached between the natural harmony and the strict necessities of the anthropic habitats. The first priority of this developing is theenvironmental legislation and biodiversity protection.

    This article provides an overview on a series of original studies conducted by the author. The aim here is to present the ideas that the author reconstructed, based on the dialectics of harmonization, regarding harmony and conflict embodied in traditional Chinese thought, and to describe how a formal psychological theory/model on interpersonal harmony and conflict was developed based on the Yin-Yang perspective. The paper also details how essential theories on interpersonal harmony and conflict were constructed under this formal model by conducting a qualitative study involving in-depth interviews with 30 adults. Psychological research in Western society has, intriguingly, long been focused more on interpersonal conflict than on interpersonal harmony. By contrast, the author's work started from the viewpoint of a materialist conception of history and dialectics of harmonization in order to reinterpret traditional Chinese thought. Next, a "dynamic model of interpersonal harmony and conflict" was developed, as a formal psychological theory, based on the real-virtual notions in the Yin-Yang perspective. Under this model, interpersonal harmony and conflict can be classified into genuine versus superficial harmony and authentic versus virtual focus conflict, and implicit/hidden conflict is regarded as superficial harmony. Subsequently, the author conducted a series of quantitative studies on interpersonal harmony and conflict within parent-child, supervisor-subordinate, and friend-friend relationships in order to verify the construct validity and the predictive validity of the dynamic model of interpersonal harmony and conflict. The claim presented herein is that Chinese traditional thought and the psychological theory/model based on the Yin-Yang perspective can be combined. Accordingly, by combining qualitative and quantitative empirical research, the relative substantial theory can be developed and the concepts can be validated. Thus, this work represents the

    The study compared IAQ, thermal quality, and lighting quality between 5 different office types in LEED-certified buildings in relation to employees' environmental satisfaction and their job performance. This was to provide workplaces where workers in each specific office environment could be provided with appropriate office settings regarding these IEQ criteria when organizations comply with LEED standards. The five types of office included private enclosed, private shared, open-plan with high cubicle over 5', open-plan with low cubicle lower than 5', and open-plan with no partitions (bullpen) offices. The study found IAQ enhanced workers' job performance in enclosed private offices more than both high cubicles and low cubicles. All four office types had higher satisfaction with the amount of light and visual comfort of light as well as more enhancement with job performance due to lighting quality than high cubicles. There was no difference in thermal quality between the five office types. IAQ and lighting quality were not different between enclosed private, enclosed shared, and bullpen office types, either. The study findings suggest a careful workplace design considering the height of partitions in LEED-certified buildings to improve employee's environmental satisfaction and job performance. (author)

    Face au rechauffement climatique, les besoins de trouver des solutions pour reduire les emissions de CO2 sont urgentes. L'optimisation des trajectoires est un des moyens pour reduire la consommation de carburant lors d'un vol. Afin de determiner la trajectoire optimale de l'avion, differents algorithmes ont ete developpes. Le but de ces algorithmes est de reduire au maximum le cout total d'un vol d'un avion qui est directement lie a la consommation de carburant et au temps de vol. Un autre parametre, nomme l'indice de cout est considere dans la definition du cout de vol. La consommation de carburant est fournie via des donnees de performances pour chaque phase de vol. Dans le cas de ce memoire, les phases d'un vol complet, soit, une phase de montee, une phase de croisiere et une phase de descente, sont etudies. Des " marches de montee " etaient definies comme des montees de 2 000ft lors de la phase de croisiere sont egalement etudiees. L'algorithme developpe lors de ce memoire est un metaheuristique, nomme la recherche de l'harmonie, qui, concilie deux types de recherches : la recherche locale et la recherche basee sur une population. Cet algorithme se base sur l'observation des musiciens lors d'un concert, ou plus exactement sur la capacite de la musique a trouver sa meilleure harmonie, soit, en termes d'optimisation, le plus bas cout.

    Based on the data of land use/cover and by using eco-economic harmony index (EEH) this paper studied the spatiotemporal characteristics of ecosystem service value on the northern slope of Tianshan Mountains, and evaluated the harmony degree of eco-economic development in the region. The results showed that the total ecosystem service value on the northern slope of Tianshan Mountains was increased from 319.93 x 10(8) yuan in 1989 to 321.26 x 10(8) yuan in 2000, with a net increment of 0.42%. The regional eco-economic development was overall at a low harmony level, being higher in eastern part than in middle and western parts, among which, eight counties had a positive value of EEH and their eco-economic development was harmonious, while seven counties had a negative value of EEH and their eco-economic development was inharmonic. The eco-economic development in the region was at the margin of harmony, and thus, more attention should be paid to strengthen the protection of eco-environment and promote the harmonious development of eco-economy to have a sustainable development.

    Full Text Available The unprecedented rate and scale of activities, simulated by human abode in its entirety, is having large and accelerating effects on the integrity of biophysical elements of spatial capital, at local, regional, and global scales. Real appreciation of these effects demands a dramatic change in human manipulation of the spatial capital. Spatial capital can be viewed as processes or a complex matrix, in which not only our spatial but social, economic, and intellectual needs are embedded. Through an extensive synthesis of literature, this study strives to situate as well as manage human abode in context of spatial capital. It focuses on the need of crafting spatial governance, which secures today’s needs without compromising the needs of abode for our future generations. For harmonious human engagement with the spatial capital, we focused on following major requisites: (i filling gaps in the understanding of processes of the respective spatial capital; (ii integration of this intellectual capital; (iii and spatial government supported by seamless institutionalisation, and governance processes in a global context. All modes of human abode are unique when analysed in the milieu of their social, economic, cultural, and intellectual yield, and their respective ecological footprint on spatial capital. An essential component of the sustainability of spatial capital is fundamental knowledge of the relevant biophysical processes, which yield the respective social, economic, cultural, and intellectual services we obtain from it. Action-oriented and integrated intellectual capital will yield the required awareness about the spatial capital, which when crystallised into proper institutions their processes will certainly produce promising outcomes for spatial management. Sustainable spatial constructs can only be produced through horizontal and vertical harmonization in governance institutions from the local to global level. It will not only help in the

    Full Text Available The nurse rostering problem is an important search problem that features many constraints. In a nurse rostering problem, these constraints are defined by processes such as maintaining work regulations, assigning nurse shifts, and considering nurse preferences. A number of approaches to address these constraints, such as penalty function methods, have been investigated in the literature. We propose two types of hybrid metaheuristic approaches for solving the nurse rostering problem, which are based on combining harmony search techniques and artificial immune systems to balance local and global searches and prevent slow convergence speeds and prematurity. The proposed algorithms are evaluated against a benchmarking dataset of nurse rostering problems; the results show that they identify better or best known solutions compared to those identified in other studies for most instances. The results also show that the combination of harmony search and artificial immune systems is better suited than using single metaheuristic or other hybridization methods for finding upper-bound solutions for nurse rostering problems and discrete optimization problems.

    Little is known about the association between environmental characteristics and types of physical activity in adolescents in a Latin American context. The aim of this study was to examine the association between perceived neighborhood environmental characteristics and different types of physical activity in 2,874 adolescents from Joao Pessoa, Paraiba State, Northeastern Brazil. The types of activity measured by questionnaire (≥10 min/day) included sports, physical exercises, active commuting and recreational activities. Neighborhood characteristics were measured by a 15-item scale. Multilevel analyses showed that adolescents who reported "having places they liked to go to" (OR = 1.41; 95%CI: 1.10-1.79) and "places with opportunities to practice" (OR = 1.29; 95%CI: 1.01-1.65) were more likely to play sports. "Seeing interesting things while walking" (OR = 1.24; 95%CI: 1.01-1.53) and "Seeing other adolescents engaged in physical activity" (OR = 1.47; 95%CI: 1,05-2,06) were associated with exercises. "Seeing other adolescents engaged in physical activity" (OR = 1.47; 95%CI: 1.18-1.82), "the neighborhood is not violent" (OR = 1.29; 95%CI: 1.04-1.60) and "having places they like to go to" (OR = 1.59; 95%CI: 1.13-2.25) were positively associated and "places with opportunities to practice" (OR = 0.79; 95%CI: 0.63-0.98) inversely related to active commuting. "Seeing other adolescents engaged in physical activities" (OR = 1.31; 95%CI: 1.05-1.63) and "seeing interesting things while walking" (OR = 1.26; 95%CI: 1.02-1.56) were associated with recreational activities. Neighborhood environmental characteristics associated with the physical activity vary with the type of practices adopted by adolescents.

  1. Environmental/lifestyle factors in the pathogenesis and prevention of type 2 diabetes.

    Environmental and lifestyle changes, in addition to the ageing of populations, are generally believed to account for the rapid global increase in type 2 diabetes prevalence and incidence in recent decades. In this review, we present a comprehensive overview of factors contributing to diabetes risk, including aspects of diet quality and quantity, little physical activity, increased monitor viewing time or sitting in general, exposure to noise or fine dust, short or disturbed sleep, smoking, stress and depression, and a low socioeconomic status. In general, these factors promote an increase in body mass index. Since loss of β-cell function is the ultimate cause of developing overt type 2 diabetes, environmental and lifestyle changes must have resulted in a higher risk of β-cell damage in those at genetic risk. Multiple mechanistic pathways may come into play. Strategies of diabetes prevention should aim at promoting a 'diabetes-protective lifestyle' whilst simultaneously enhancing the resistance of the human organism to pro-diabetic environmental and lifestyle factors. More research on diabetes-protective mechanisms seems warranted.

    Different elements of the environment have been posited to influence type 2 diabetes mellitus (T2DM). This systematic review summarizes evidence on the environmental determinants of T2DM identified in four databases. It proposes a theoretical framework illustrating the link between environment and T2DM, and briefly discusses some methodological challenges and potential solutions, and opportunities for future research. Walkability, air pollution, food and physical activity environment and roadways proximity were the most common environmental characteristics studied. Of the more than 200 reported and extracted relationships assessed in 60 studies, 82 showed significant association in the expected direction. In general, higher levels of walkability and green space were associated with lower T2DM risk, while increased levels of noise and air pollution were associated with greater risk. Current evidence is limited in terms of volume and study quality prohibiting causal inferences. However, the evidence suggests that environmental characteristics may influence T2DM prevention, and also provides a reasonable basis for further investigation with better quality data and longitudinal studies with policy-relevant environmental measures. This pursuit of better evidence is critical to support health-orientated urban design and city planning. PMID:29304014

    Data from the NHLBI Twin Study were used to investigate the genetic component in a number of Type A measures given to these twins during a second cardiovascular examination. Specifically, the objective of the current study was to determine the extent to which various Type A measures are influenced by genetic effects and by measurable environmental and cultural factors. Analyses of these data for twins yielded a number of results. First, the Type A behavior pattern as assessed by the structured interview was only weakly associated with self-report inventories developed as alternatives to the structured interview. Second, among the self-report measures of Type A, only the Thurstone Temperament Schedule Active scale showed a clear significant genetic component. Most important, a number of demographic and social characteristics known to be associated with the various Type A scales had a differential effect on twin similarities. Specifically, for the job involvement subscale of the Jenkins Activity Survey, twins of both zygosities became equally similar after adjustments for covariates, while no effect on twin similarity was noted for the Thurstone Temperament Schedule Active scale. It is concluded that a complex constellation of genetic predispositions and acquired behaviors underlies the Type A behavior construct.

    Inadequate discriminatory power to distinguish between L. pneumophila isolates, especially those belonging to disease-related prevalent sequence types (STs) such as ST1, ST36 and ST47, is an issue of SBT scheme. In this study, we developed a multilocus sequence typing (MLST) scheme based on two non-virulence loci (trpA, cca) and three virulence loci (icmK, lspE, lssD), to genotype 110 L. pneumophila isolates from various natural and artificial water sources in Guangdong province of China, and compared with the SBT. The isolates were assigned to 33 STs of the SBT and 91 new sequence types (nSTs) of the MLST. The indices of discrimination (IODs) of SBT and MLST were 0.920 and 0.985, respectively. Maximum likelihood trees of the concatenated SBT and MLST sequences both showed distinct phylogenetic relationships between the isolates from the two environments. More intragenic recombinations were detected in nSTs than in STs, and they were both more abundant in natural water isolates. We found out the MLST had a high discriminatory ability for the disease-associated ST1 isolates: 22 ST1 isolates were assigned to 19 nSTs. Furthermore, we assayed the discrimination of the MLST for 29 reference strains (19 clinical and 10 environmental). The clinical strains were assigned to eight STs and ten nSTs. The MLST could also subtype the prevalent clinical ST36 or ST47 strains: eight ST36 strains were subtyped into three nSTs and two ST47 strains were subtyped into two nSTs. We found different distribution patterns of nSTs between the environmental and clinical ST36 isolates, and between the outbreak clinical ST36 isolates and the sporadic clinical ST36 isolates. These results together revealed the MLST scheme could be used as part of a typing scheme that increased discrimination when necessary.

    This forum response adds a conceptualization of harmony to Dopico and Vázquez' investigation of pedagogy that combines citizen science, environmental and cross-cultural research, and service-learning. Placing many appropriate and significant aspects of culturally situated science education in an authentically relational context beyond the classroom, this paper calls attention to insightful contributions and new directions for research, such as the process of inducing or eluding nihilism regarding ecological issues. How can such a question be researched effectively in order to learn about the family of pedagogies emerging in response to the need for more ecologically conscious and relationally authentic teaching across many disciplines? In this paper, I use a Vygotskian framework and an abbreviated case study of agricultural service-learning from my research, drawing attention to the importance of students' culturally-mediated construction of setting as they interact in older and newer ways.

    Full Text Available The process of gasification of carbonaceous fuels is a technology with a long-standing practice. In recent years, the technology has been extensively developing to produce energy or chemicals on the basis of obtained gas. Studies focused on the improvement of the gasification process aims at developing the process by increasing environmental safety, the efficiency and the possibilities to utilize various types of alternative fuels (post-consumer waste, various types of biomass waste, by-products and post-process residues, sewage sludge independently or by co-gasification with coal. The choice of the gas purification system, the process operating parameters and introducing the necessary modifications to the existing technologies are essential steps while processing these kinds of feedstock, with regard to their individual characteristics. This paper discusses selected environmental aspects of the gasification and co-gasification of municipal solid waste, sewage sludge, various types of biomass waste and post-process residues. Selected alternative fuels are also characterized, focusing on the influence of their presence in the feedstock in terms of production and the emission of polychlorinated organic compounds, tars, heavy metals and toxic elements.

    Full Text Available This paper presents a novel approach to multi-type distributed generation (DG planning based on the analysis of investment and income brought by grid-connected DG. Firstly, the timing characteristics of loads and DG outputs, as well as the environmental benefits of DG are analyzed. Then, on the basis of the classification of daily load sequences, the typical daily load sequence and the typical daily output sequence of DG per unit capacity can be computed. The proposed planning model takes the location, capacity and types of DG into account as optimization variables. An improved adaptive genetic algorithm is proposed to solve the model. Case studies have been carried out on the IEEE 14-node distribution system to verify the feasibility and effectiveness of the proposed method and model.

  9. Bach Is the Father of Harmony: Revealed by a 1/f Fluctuation Analysis across Musical Genres.

    Directory of Open Access Journals (Sweden)

    Dan Wu

    Full Text Available Harmony is a fundamental attribute of music. Close connections exist between music and mathematics since both pursue harmony and unity. In music, the consonance of notes played simultaneously partly determines our perception of harmony; associates with aesthetic responses; and influences the emotion expression. The consonance could be considered as a window to understand and analyze harmony. Here for the first time we used a 1/f fluctuation analysis to investigate whether the consonance fluctuation structure in music with a wide range of composers and genres followed the scale free pattern that has been found for pitch, melody, rhythm, human body movements, brain activity, natural images and geographical features. We then used a network graph approach to investigate which composers were the most influential both within and across genres. Our results showed that patterns of consonance in music did follow scale-free characteristics, suggesting that this feature is a universally evolved one in both music and the living world. Furthermore, our network analysis revealed that Bach's harmony patterns were having the most influence on those used by other composers, followed closely by Mozart.

    Although the concepts of harmonious and obsessive passion have been productive in explaining why people eagerly engage in such activities as sports, Internet use, and gambling, previous research has not yet extended these models to explain alcohol and marijuana use among college students. The current research was conducted to clarify the relationships among harmonious and obsessive passion, alcohol and marijuana use, and negative consequences. Two studies were conducted using online assessments. In Study 1, 748 heavy drinking college students (58% female) were recruited and completed measures of passion for drinking alcohol, alcohol use, and alcohol-related negative consequences. In Study 2, 352 regular marijuana-using students (54% female) were recruited and completed assessments of marijuana passion, marijuana use, and marijuana-related consequences. Study 1 found that among heavy drinking college students, harmonious passion was a stronger predictor of increased consumption than was obsessive passion, whereas obsessive passion was a stronger predictor of alcohol-related problems than was harmonious passion. Study 2 revealed similar findings with regard to harmonious passion predicting marijuana consumption; however, unlike Study 1, no significant difference between the passions was found in predicting marijuana-related problems. This research provides a novel perspective on motivation for alcohol and marijuana use. Findings suggest that understanding the locus of young adults' passion for substance use may be helpful in identifying those who are likely to develop a substance use disorder and therefore may be the most in need of assistance and intervention.

    Full Text Available We presented a new hybrid method that combines cellular harmony search algorithms with the Smallest-Small-World theory. A harmony search (HS algorithm is based on musical performance processes that occur when a musician searches for a better state of harmony. Harmony search has successfully been applied to a wide variety of practical optimization problems. Most of the previous researches have sought to improve the performance of the HS algorithm by changing the pitch adjusting rate and harmony memory considering rate. However, there has been a lack of studies to improve the performance of the algorithm by the formation of population structures. Therefore, we proposed an improved HS algorithm that uses the cellular automata formation and the topological structure of Smallest-Small-World network. The improved HS algorithm has a high clustering coefficient and a short characteristic path length, having good exploration and exploitation efficiencies. Nine benchmark functions were applied to evaluate the performance of the proposed algorithm. Unlike the existing improved HS algorithm, the proposed algorithm is expected to have improved algorithmic efficiency from the formation of the population structure.

    Full Text Available Coastal lagoon types of Western Greece were allocated to a spectrum of meso to polyhaline chocked lagoons; poly to euhaline restricted lagoons; and euhaline restricted lagoons along the Ionian Sea coast. This diversity comprises wide ranges of physical, chemical and environmental parameters in a seasonal and annual scale, which explains the variability in the distribution of benthic macrophytes. Four different macrophyte assemblages were distinguished, characterized by annual or perennial species. Extensive statistical analysis showed that salinity and nitrate concentrations had a great impact on the composition and distribution of macrophyte assemblages into lagoon types that also changed their abundance on a seasonal and annual scale. During the monitoring period, an important salinity shift in a chocked lagoon might cause the gradual loss of Zostera noltii and its replacement by Ruppia cirrhosa. Restricted lagoons were characterized by higher species diversity, while the other three identified macrophyte assemblages were dominated by the angiosperms Ruppia cirrhosa and Cymodocea nodosa. This integrated study of coastal lagoons is likely to be broadly applicable, since it was based on important parameters affecting such ecosystems, and the provided links between macrophyte assemblages and abiotic factors are of critical importance to improve management and environmental policies.

    Full Text Available The objective of the present study was to investigate the association of hs-CRP levels with environmental risk factors of diabetic nephropathy like smoking, drinking alcohol, diet, age of diabetic patient, duration of diabetes, medication of diabetes, and blood pressure medication. A hospital-based quantitative study was conducted at the Department of Clinical Biochemistry of Manipal Teaching Hospital (MTH Pokhara, Nepal, with 89 patients suffering from type 2 diabetes. Blood samples (n=89 from the patients were collected and the serums were separated. On the other hand, data on environmental risk factors of nephropathy were collected by using standard questionnaire. In this study, serum hs-CRP level was not found to be correlated with smoking (p=0.111, alcohol consumption (p=0.722, diet (p=0.496, duration of diabetes (p=0.519, age of diabetic patient (p=0.369, medication of diabetes (p=0.734, and blood pressure medication (p=0.625. Hence, our study concludes that serum hs-CRP value in type 2 diabetic patients is insignificantly correlated with the risk factors especially smoking, drinking alcohol, diet, duration of diabetes, age of diabetic patient, medication of diabetes, and medication of blood pressure.

    Molecular analysis of dissimilatory nitrite reductase genes (nirS) was conducted using a customized microarray containing 165 nirS probes (archetypes) to identify members of sedimentary denitrifying communities. The goal of this study was to examine denitrifying community responses to changing environmental variables over spatial and temporal scales in the New River Estuary (NRE), NC, USA. Multivariate statistical analyses revealed three denitrifier assemblages and uncovered 'generalist' and 'specialist' archetypes based on the distribution of archetypes within these assemblages. Generalists, archetypes detected in all samples during at least one season, were commonly world-wide found in estuarine and marine ecosystems, comprised 8%-29% of the abundant NRE archetypes. Archetypes found in a particular site, 'specialists', were found to co-vary based on site specific conditions. Archetypes specific to the lower estuary in winter were designated Cluster I and significantly correlated by sediment Chl a and porewater Fe 2+ . A combination of specialist and more widely distributed archetypes formed Clusters II and III, which separated based on salinity and porewater H 2 S respectively. The co-occurrence of archetypes correlated with different environmental conditions highlights the importance of habitat type and niche differentiation among nirS-type denitrifying communities and supports the essential role of individual community members in overall ecosystem function. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

    Full Text Available Impairment of hippocampal adult neurogenesis in aging or degenerating brain is a well-known phenomenon caused by the shortage of brain stem cell pool, alterations in the local microenvironment within the neurogenic niches, or deregulation of stem cell development. Environmental enrichment (EE has been proposed as a potent tool to restore brain functions, to prevent aging-associated neurodegeneration, and to cure neuronal deficits seen in neurodevelopmental and neurodegenerative disorders. Here, we report our data on the effects of environmental enrichment on hippocampal neurogenesis in vivo and neurosphere-forming capacity of hippocampal stem/progenitor cells in vitro. Two models – Alzheimer’s type of neurodegeneration and physiological brain aging – were chosen for the comparative analysis of EE effects. We found that environmental enrichment greatly affects the expression of markers specific for stem cells, progenitor cells and differentiated neurons (Pax6, Ngn2, NeuroD1, NeuN in the hippocampus of young adult rats or rats with Alzheimer’s disease (AD model but less efficiently in aged animals. Application of time-lag mathematical model for the analysis of impedance traces obtained in real-time monitoring of cell proliferation in vitro revealed that EE could restore neurosphere-forming capacity of hippocampal stem/progenitor cells more efficiently in young adult animals (fourfold greater in the control group comparing to the AD model group but not in the aged rats (no positive effect of environmental enrichment at all. In accordance with the results obtained in vivo, EE was almost ineffective in the recovery of hippocampal neurogenic reserve in vitro in aged, but not in amyloid-treated or young adult, rats. Therefore, EE-based neuroprotective strategies effective in Aβ-affected brain could not be directly extrapolated to aged brain.

    Cryptococcus neoformans and Cryptococcus gattii are the main causative agents of cryptococcosis, a systemic fungal disease that affects internal organs and skin, and which is acquired by inhalation of spores or encapsulated yeasts. It is currently known that the C. neoformans/C. gattii species complex has a worldwide distribution, however, some molecular types seem to prevail in certain regions. Few environmental studies of Cryptococcus have been conducted in the Brazilian Amazon. This is the first ecological study of the pathogenic fungi C. neoformans/C. gattii species complex in the urban area of Manaus, Amazonas, Brazil. A total of 506 samples from pigeon droppings (n = 191), captive bird droppings (n = 60) and tree hollows (n = 255) were collected from June 2012 to January 2014 at schools and public buildings, squares, pet shops, households, the zoo and the bus station. Samples were plated on niger seed agar (NSA) medium supplemented with chloramphenicol and incubated at 25°C for 5 days. Dark-brown colonies were isolated and tested for thermotolerance at 37°C, cycloheximide resistance and growth on canavanine-glycine-bromothymol blue agar. Molecular typing was done by PCR-RFLP. Susceptibility to the antifungal drugs amphotericin B, fluconazole, itraconazole and ketoconazole was tested using Etest(®) strips. In total, 13 positive samples were obtained: one tree hollow (C. gattiiVGII), nine pigeon droppings (C. neoformansVNI) and three captive bird droppings (C. neoformansVNI). The environmental cryptococcal isolates found in this study were of the same molecular types as those responsible for infections in Manaus. © 2016 Blackwell Verlag GmbH.

    2016-03-01

    This paper proposes a novel method to address reliability and technical problems of microgrids (MGs) based on designing a number of self-adequate autonomous sub-MGs via adopting MGs clustering thinking. In doing so, a multi-objective optimization problem is developed where power losses reduction, voltage profile improvement and reliability enhancement are considered as the objective functions. To solve the optimization problem a hybrid algorithm, named HS-GA, is provided, based on genetic and harmony search algorithms, and a load flow method is given to model different types of DGs as droop controller. The performance of the proposed method is evaluated in two case studies. The results provide support for the performance of the proposed method. Copyright © 2015 ISA. Published by Elsevier Ltd.

    Studies with pure cultures of dissimilatory metal-reducing microorganisms have demonstrated that outer-surface c-type cytochromes are important electron transfer agents for the reduction of metals, but previous environmental proteomic studies have typically not recovered cytochrome sequences from subsurface environments in which metal reduction is important. Gel-separation, heme-staining and mass spectrometry of proteins in groundwater from in situ uranium bioremediation experiments identified a putative c-type cytochrome, designated Geobacter subsurface c-type cytochrome A (GscA), encoded within the genome of strain M18, a Geobacter isolate previously recovered from the site. Homologs of GscA were identified in the genomes of other Geobacter isolates in the phylogenetic cluster known as subsurface clade 1, which predominates in a diversity of Fe(III)-reducing subsurface environments. Most of the gscA sequences recovered from groundwater genomic DNA clustered in a tight phylogenetic group closely related to strain M18. GscA was most abundant in groundwater samples in which Geobacter sp. predominated. Expression of gscA in a strain of Geobacter sulfurreducens that lacked the gene for the c-type cytochrome OmcS, thought to facilitate electron transfer from conductive pili to Fe(III) oxide, restored the capacity for Fe(III) oxide reduction. Atomic force microscopy provided evidence that GscA was associated with the pili. These results demonstrate that a c-type cytochrome with an apparent function similar to that of OmcS is abundant when Geobacter sp. are abundant in the subsurface, providing insight into the mechanisms for the growth of subsurface Geobacter sp. on Fe(III) oxide and suggesting an approach for functional analysis of other Geobacter proteins found in the subsurface.

    Bullying and violence, which can bring detrimental effects, are situations which young people have to face in their process of development. Though school bullying has been a spreading and explicit problem in Hong Kong schools, most of the programs or guidelines dealing with the problem lack citywide, recognized initiatives and the effectiveness of these programs is unknown due to the lack of evaluation. The present paper discusses preventing school bullying from a developmental guidance perspective, using the positive youth development paradigm and promoting the values of harmony and forgiveness at the whole-school level to cultivate a harmonious school culture as a way of combating school bullying.

    2011-05-01

    In this first investigation of genetic and environmental influences on children's values, 271 German twin pairs (50.2% boys) reported their values at ages 7-11 years using the Portrait Values Questionnaire (Schwartz & Rubel, 2005). We distinguished between gender-neutral (conservation vs. openness to change) and gender-typed (self-transcendence vs. self-enhancement) values. Boys differed from girls in the importance given to gender-typed benevolence, achievement, and power values. Gender-neutral values showed moderate (.34) and gender-typed values showed higher (.49) heritability, with nonshared environment and error accounting for the remaining variance. For both sexes, substantial genetic effects accounted for the importance children gave to their respective gender-stereotypical end of the self-transcendence versus self-enhancement dimension. However, dramatic sex differences emerged in the gender-atypical end of the distribution. For girls, low self-transcendence (high gender-atypical values) showed a large (.76) group heritability. For boys, gender-atypical values (high self-transcendence) showed no heritability and a modest (.10) shared environment effect. (c) 2011 APA, all rights reserved.

  11. Lung macrophage uptake of unopsonized environmental particulates: Role of scavenger-type receptors

    1995-07-01

    The receptors responsible for avid alveolar macrophage (AM) phagocytosis of unopsonized environmental particulates have not been well defined. This study used flow cytometry to quantitate the effects of a panel of soluble ligands for macrophage adhesion receptors on AM binding of unopsonized environmental dusts (titanium dioxide, TiO{sub 2}; iron oxide, Fe{sub 2}O{sub 3}; {alpha}-quartz, SiO{sub 2}; diesel engine exhaust dust) or fluorescent latex beads. Polyanionic ligands of the macrophage scavenger receptor (SR) for acetylated-LDL caused marked inhibition of AM binding of the oxide particles and latex beads (e.g., TiO{sub 2} binding; polyinosinic acid (polyl), 10 {mu}g/ml: 70.2 {+-} 1.5% inhibition, mean {+-} SE, n = 11). In contrast, no inhibition was seen with the polyanions heparin and chondroitin sulfate (chond-S), or dextran, consistent with the known inhibitor profile of macrophage SRs for acetylated-LDL. AM uptake of latex or SiO{sub 2} beads instilled into lungs of hamsters was inhibited by administration of polyl but not chondroitin sulfate (AM beads per cell: control, 6.1 {+-} 0.7; polyl, 3.5 {+-} 0.2; chond-S, 5.1 {+-} 0.7, n {ge} 4, p < 0.05 for control vs polyl) indicating macrophage SRs operate in vivo as well as in vitro. In contrast, AM binding of the carbonaceous diesel dust particles was not inhibited by any ligand tested. AM uptake of unopsonized TiO{sub 2}, SR ligands or acetylated LDL caused no significant activation of AM respiratory burst or TNF production, consistent with past observations that opsonin-independent phagocytosis of inert particles by normal AMs is not accompanied by pro-inflammatory activation. These data implicate macrophage-type SRs in AM binding of charged environmental particles and indicate that distinct mechanisms mediate binding of carbonaceous dusts. 54 refs., 7 figs., 4 tabs.

    The genomes of Pseudomonas aeruginosa isolates of the new sequence type ST-1146, three environmental (P37, P47 and P49) and one clinical (SD9) isolates, with differences in their antibiotic susceptibility profiles have been sequenced and analysed. The genomes were mapped against P. aeruginosa PAO1-UW and UCBPP-PA14. The allelic profiles showed that the highest number of differences were in “Related to phage, transposon or plasmid” and “Secreted factors” categories. The clinical isolate showed a number of exclusive alleles greater than that for the environmental isolates. The phage Pf1 region in isolate SD9 accumulated the highest number of nucleotide substitutions. The ORF analysis of the four genomes assembled de novo indicated that the number of isolate-specific genes was higher in isolate SD9 (132 genes) than in isolates P37 (24 genes), P47 (16 genes) and P49 (21 genes). CRISPR elements were found in all isolates and SD9 showed differences in the spacer region. Genes related to bacteriophages F116 and H66 were found only in isolate SD9. Genome comparisons indicated that the isolates of ST-1146 are close related, and most genes implicated in pathogenicity are highly conserved, suggesting a genetic potential for infectivity in the environmental isolates similar to the clinical one. Phage-related genes are responsible of the main differences among the genomes of ST-1146 isolates. The role of bacteriophages has to be considered in the adaptation processes of isolates to the host and in microevolution studies. PMID:25329302

    Uncertainty still exists regarding the role of some environmental risk in the development of type 1 diabetes mellitus (T1DM) both globally and in Egypt. The objective here was to explore the potential environmental risk factors associated with the development of T1DM among children in Egypt. A case-controlled study of 204 T1DM children and an equal number of age and sex-matched controls was conducted in Assiut, Egypt. Data regarding the parental, gestational, neonatal, and childhood possible risk factors for T1DM were evaluated. The final sex adjusted multivariable logistic regression model revealed that the risk for T1DM was significantly higher among rural residents (aOR = 2.03, 95% CI: 1.30-4.25), those with parental history of T1DM (aOR = 9.03, 95% CI: 1.02-83.32), birth through cesarean section (aOR = 2.13, 95% CI: 1.09-5.03), and having history of early introduction of cow milk in the first year of life (aOR = 19.49, 95% CI: 8.73-45.53). On the other hand, a protective effect was observed between at least six months' breastfeeding, vitamin D supplementation in the first year of life, high physical activity, and the development of T1DM. Educational programs should be adopted to improve awareness and knowledge of the parents to avoid the increased risk factors and encourage protective practices.

    This study examines the use of commercially available automatic speech recognition (ASR) across microphone options as access to environmental control for individuals with and without dysarthria. A study of two groups of speakers (typical speech and dysarthria), was conducted to understand their performance using ASR and various microphones for environmental control. Specifically, dependent variables examined included attempts per command, recognition accuracy, frequency of error type, and perceived workload. A further sub-analysis of the group of participants with dysarthria examined the impact of severity. Results indicated a significantly larger number of attempts were required (P = 0.007), and significantly lower recognition accuracies were achieved by the dysarthric participants (P = 0.010). A sub-analysis examining severity demonstrated no significant differences between the typical speakers and participants with mild dysarthria. However, significant differences were evident (P = 0.007, P = 0.008) between mild and moderate-severe dysarthric participants. No significant differences existed across microphones. A higher frequency of threshold errors occurred for typical participants and no response errors for moderate-severe dysarthrics. There were no significant differences on the NASA Task Load Index.

    The responses of soil respiration to environmental conditions have been studied extensively in various ecosystems. However, little is known about the impacts of temperature and moisture on soils respiration under biological soil crusts. In this study, CO2 efflux from biologically-crusted soils was measured continuously with an automated chamber system in Ningxia, northwest China, from June to October 2012. The highest soil respiration was observed in lichen-crusted soil (0.93 ± 0.43 µmol m-2 s-1) and the lowest values in algae-crusted soil (0.73 ± 0.31 µmol m-2 s-1). Over the diurnal scale, soil respiration was highest in the morning whereas soil temperature was highest in the midday, which resulted in diurnal hysteresis between the two variables. In addition, the lag time between soil respiration and soil temperature was negatively correlated with the soil volumetric water content and was reduced as soil water content increased. Over the seasonal scale, daily mean nighttime soil respiration was positively correlated with soil temperature when moisture exceeded 0.075 and 0.085 m3 m-3 in lichen- and moss-crusted soil, respectively. However, moisture did not affect on soil respiration in algae-crusted soil during the study period. Daily mean nighttime soil respiration normalized by soil temperature increased with water content in lichen- and moss-crusted soil. Our results indicated that different types of biological soil crusts could affect response of soil respiration to environmental factors. There is a need to consider the spatial distribution of different types of biological soil crusts and their relative contributions to the total C budgets at the ecosystem or landscape level.

    Cryptococcus neoformans and C. gattii are the major cause of fungal meningitis, a potentially lethal mycosis. Since pigeon excreta and other environmental sources can be considered a significant environmental reservoir of this species in urban areas, 100 samples of pigeon excreta and 420 samples from Eucalyptus camaldulensis and Olea europaea (olive tree) around the city of Tripoli, Libya, were collected. C. neoformans was isolated and identified using standard biochemical assays from 46 samples: 34 from pigeon droppings, 3 from Eucalyptus trees and 9 from olive trees. Molecular typing revealed that all isolates from pigeon droppings belonged to molecular type VNI (C. neoformans var. grubii) and mating type αA, whereas those from trees included also the molecular type VNII and VNIII (AD hybrids). The present study reports, for the first time, information about the distribution of species, mating types and molecular types of C. neoformans/C. gattii species complex in Libya.

  1. On the use of harmony search algorithm in the training of wavelet neural networks

    Science.gov (United States)

    Lai, Kee Huong; Zainuddin, Zarita; Ong, Pauline

    2015-10-01

    Wavelet neural networks (WNNs) are a class of feedforward neural networks that have been used in a wide range of industrial and engineering applications to model the complex relationships between the given inputs and outputs. The training of WNNs involves the configuration of the weight values between neurons. The backpropagation training algorithm, which is a gradient-descent method, can be used for this training purpose. Nonetheless, the solutions found by this algorithm often get trapped at local minima. In this paper, a harmony search-based algorithm is proposed for the training of WNNs. The training of WNNs, thus can be formulated as a continuous optimization problem, where the objective is to maximize the overall classification accuracy. Each candidate solution proposed by the harmony search algorithm represents a specific WNN architecture. In order to speed up the training process, the solution space is divided into disjoint partitions during the random initialization step of harmony search algorithm. The proposed training algorithm is tested onthree benchmark problems from the UCI machine learning repository, as well as one real life application, namely, the classification of electroencephalography signals in the task of epileptic seizure detection. The results obtained show that the proposed algorithm outperforms the traditional harmony search algorithm in terms of overall classification accuracy.

    2013-01-01

    Full Text Available Harmony search (HS algorithm is an emerging population-based metaheuristic algorithm, which is inspired by the music improvisation process. The HS method has been developed rapidly and applied widely during the past decade. In this paper, an improved global harmony search algorithm, named harmony search based on teaching-learning (HSTL, is presented for high dimension complex optimization problems. In HSTL algorithm, four strategies (harmony memory consideration, teaching-learning strategy, local pitch adjusting, and random mutation are employed to maintain the proper balance between convergence and population diversity, and dynamic strategy is adopted to change the parameters. The proposed HSTL algorithm is investigated and compared with three other state-of-the-art HS optimization algorithms. Furthermore, to demonstrate the robustness and convergence, the success rate and convergence analysis is also studied. The experimental results of 31 complex benchmark functions demonstrate that the HSTL method has strong convergence and robustness and has better balance capacity of space exploration and local exploitation on high dimension complex optimization problems.

    2014-09-01

    Harmony is defined as the pleasing combination of elements of a system to form an all-inclusive, all involving and more productive team. The aim of this present review was to investigate the factors militating against harmony among healthcare professional in the Nigerian healthcare delivery system. This review was carried out by searching through literature on the topic that bother on harmony among health professions in the health sector. Literature search and reports from previous studies indicates that harmony among health workers is pivotal to improving the health indices. However, available evidence suggests that unlike in the developed world, health care professionals do not collaborate well together in Nigeria because of the claim of superiority of a particular health professional over others. This has often resulted in inter-professional conflict which is threatening to tear the health sector apart to the detriment of the patients. The Nigeria health system should be based on team work. Health professionals from a variety of disciplines should work together to deliver the best possible healthcare services to all Nigerians. All members of the team are equally valuable and essential to the smooth running of hospitals. Hospitals should ideally be headed by health administrators or by a qualified member of any of the professions in the health sector. Copyright © 2014 Hainan Medical College.

  14. An Improved Harmony Search algorithm for optimal scheduling of the diesel generators in oil rig platforms

    International Nuclear Information System (INIS)

    Yadav, Parikshit; Kumar, Rajesh; Panda, S.K.; Chang, C.S.

    2011-01-01

    Harmony Search (HS) algorithm is music based meta-heuristic optimization method which is analogous with the music improvisation process where musician continue to polish the pitches in order to obtain better harmony. The paper focuses on the optimal scheduling of the generators to reduce the fuel consumption in the oil rig platform. The accurate modeling of the specific fuel consumption is significant in this optimization. The specific fuel consumption has been modeled using cubic spline interpolation. The SFC curve is non-linear and discrete in nature, hence conventional methods fail to give optimal solution. HS algorithm has been used for optimal scheduling of the generators of both equal and unequal rating. Furthermore an Improved Harmony Search (IHS) method for generating new solution vectors that enhances accuracy and convergence rate of HS has been employed. The paper also focuses on the impacts of constant parameters on Harmony Search algorithm. Numerical results show that the IHS method has good convergence property. Moreover, the fuel consumption for IHS algorithm is lower when compared to HS and other heuristic or deterministic methods and is a powerful search algorithm for various engineering optimization problems.

    Full Text Available Cryptosporidiosis has recently attracted attention as an emerging waterborne and foodborne disease as well as an opportunistic infection in HIV infected individuals. The lack of genetic information, however, has resulted in confusion in the taxonomy of Cryptosporidium parasites and in the development of molecular tools for the identification and typing of oocysts in environmental samples. Phylogenetic analysis of the small subunit ribosomal RNA (SSU rRNA gene has shown that the genus Cryptosporidium is comprised of several distinct species. Our data show the presence of at least four species: C. parvum, C. muris, C. baileyi and C. serpentis (C. meleagridis, C. nasorum and C. felis were not studied. Within each species, there is some sequence variation. Thus, various genotypes (genotype 1, genotype 2, guinea pig genotype, monkey genotype and koala genotype, etc. of C. parvum differ from each other in six regions of the SSU rRNA gene. Information on polymorphism in Cryptosporidium parasites has been used in the development of species and strain-specific diagnostic tools. Use of these tools in the characterization of oocysts various samples indicates that C. parvum genotype 1 is the strain responsible for most human Cryptosporidium infections. In contrast, genotype 2 is probably the major source for environmental contamination of environment, and has been found in most oysters examined from Chesapeake Bay that serve as biologic monitors of surface water. Parasites of Cryptosporidium species other than C. parvum have not been detected in HIV+ individuals, indicating that the disease in humans is caused only by C. parvum.

  18. Is the detection of aquatic environmental DNA influenced by substrate type?

    Directory of Open Access Journals (Sweden)

    Andrew S Buxton

    Full Text Available The use of environmental DNA (eDNA to assess the presence-absence of rare, cryptic or invasive species is hindered by a poor understanding of the factors that can remove DNA from the system. In aquatic systems, eDNA can be transported out either horizontally in water flows or vertically by incorporation into the sediment. Equally, eDNA may be broken down by various biotic and abiotic processes if the target organism leaves the system. We use occupancy modelling and a replicated mesocosm experiment to examine how detection probability of eDNA changes once the target species is no longer present. We hypothesise that detection probability falls faster with a sediment which has a large number of DNA binding sites such as topsoil or clay, over lower DNA binding capacity substrates such as sand. Water removed from ponds containing the target species (the great crested newt initially showed high detection probabilities, but these fell to between 40% and 60% over the first 10 days and to between 10% and 22% by day 15: eDNA remained detectable at very low levels until day 22. Very little difference in detection was observed between the control group (no substrate and the sand substrate. A small reduction in detection probability was observed between the control and clay substrates, but this was not significant. However, a highly significant reduction in detection probability was observed with a topsoil substrate. This result is likely to have stemmed from increased levels of PCR inhibition, suggesting that incorporation of DNA into the sentiment is of only limited importance. Surveys of aquatic species using eDNA clearly need to take account of substrate type as well as other environmental factors when collecting samples, analysing data and interpreting the results.

    The harmony of the human gait was recently found to be related to the golden ratio value (ϕ). The ratio between the duration of the stance and that of the swing phases of a gait cycle was in fact found to be close to ϕ, which implies that, because of the fractal property of autosimilarity of that number, the gait ratios stride/stance, stance/swing, swing/double support, were not significantly different from one another. We studied a group of patients with cerebellar ataxia to investigate how the differences between their gait ratios and the golden ratio are related to efficiency and stability of their gait, assessed by energy expenditure and stride-to-stride variability, respectively. The gait of 28 patients who were affected by degenerative cerebellar ataxia and of 28 healthy controls was studied using a stereophotogrammetric system. The above mentioned gait ratios, the energy expenditure estimated using the pelvis reconstructed method and the gait variability in terms of the stride length were computed, and their relationships were analyzed. Matching procedures have also been used to avoid multicollinearity biases. The gait ratio values of the patients were farther from the controls (and hence from ϕ), even in speed matched conditions (P=0.011, Cohen's D=0.76), but not when the variability and energy expenditure were matched between the two groups (Cohen's D=0.49). In patients with cerebellar ataxia, the farther the stance-swing ratio was from ϕ, the larger the total mechanical work (R 2 adj =0.64). Further, a significant positive correlation was observed between the difference of the gait ratio from the golden ratio and the severity of the disease (R=0.421, P=0.026). Harmony of gait appears to be a benchmark of physiological gait leading to physiological energy recovery and gait reliability. Neurorehabilitation of patients with ataxia might benefit from the restoration of harmony of their locomotor patterns. Copyright © 2017. Published by Elsevier Ltd.

  2. COMPANIONSHIP WITH NATURE IN ASIAN TRADITIONS: A RESOURCE FOR ENVIRONMENTAL EDUCATION

    Directory of Open Access Journals (Sweden)

    MD. MUNIR HOSSAIN TALUKDER

    2014-11-01

    Full Text Available What is the meaning of ‘nature’ in Asian cultures? How do Asian people perceive their relations to nature? What types of environmental ethics do Asian cultures exhibit? This paper considers these questions in two major Asian traditions, Indian and Chinese. It points out that the concept of nature has played a crucial role in Asian people’s lifestyles, beliefs, and ethical thinking. To them, nature is seen not merely as a means of livelihood, but rather the fountain of harmony, spirituality, and inspiration. The paper examines whether Asian environmental ethics is anthropocentric or nonanthropocentric. It concludes that, despite some limitations, Asian traditions nourish an alternative environmental ethic, which is a companionship with nature, and should be granted as a valuable resource for environmental education.

    We measure the radial profiles of the stellar velocity dispersions, σ(R), for 90 early-type galaxies (ETGs) in the MASSIVE survey, a volume-limited integral-field spectroscopic (IFS) galaxy survey targeting all northern-sky ETGs with absolute K-band magnitude MK galaxies with sufficient radial coverage to determine γouter we find 36 per cent to have rising outer dispersion profiles, 30 per cent to be flat within the uncertainties and 34 per cent to be falling. The fraction of galaxies with rising outer profiles increases with M* and in denser galaxy environment, with 10 of the 11 most massive galaxies in our sample having flat or rising dispersion profiles. The strongest environmental correlations are with local density and halo mass, but a weaker correlation with large-scale density also exists. The average γouter is similar for brightest group galaxies, satellites and isolated galaxies in our sample. We find a clear positive correlation between the gradients of the outer dispersion profile and the gradients of the velocity kurtosis h4. Altogether, our kinematic results suggest that the increasing fraction of rising dispersion profiles in the most massive ETGs are caused (at least in part) by variations in the total mass profiles rather than in the velocity anisotropy alone.

    Type 1 fimbriae (T1F) are well characterised cell surface organelles expressed by Escherichia coli and required for adherence to mannosylated host tissue. They satisfy molecular Koch's postulates as a virulence determinant and a host-adapted role has been reinforced by reports that T1F expression is repressed at submammalian temperatures. Analysis of a group of 136 environmental and animal E. coli isolates that express T1F at 37°C showed that 28% are also capable of expression at 20°C, in a phase variable manner. The heterogeneous proportions varied widely, and although growth temperature impacted the total proportion expressing T1F, there was no direct correlation between growth at 37°C and 20°C, indicative of differences in thermoregulation of the genetic switch (fimS) that controls phase variation. Specificities of the adhesin (FimH) also varied between the isolates: most bound to α-(1-3) mannan and yeast extracts as expected, but some recognised β-(1-4)-mannans and N-linked glycoproteins from plants, and T1F from two of the isolates mediated binding to plant roots. The results expand our view of a well-described adherence factor to show alternative expression profiles and adhesin specificities, which in turn may confer an advantage for certain isolates in alternative hosts and habitats. © FEMS 2016.

    Type Ia supernovae are excellent distance indicators and provide a uniqueprobe for measuring the expansion history of the Universe. They playkey roles both in measuring the Hubble Constant, H0, and the dark energyequation of state, w. However their exact nature remains uncertain andastrophysical dependencies have been identified and shown to significantlyaffect the measurements of H0 and w. Recently we have used a uniquesample having local host information to demonstrate that, far from beinga problem, correlations between standardized SN Ia brightnesses andproperties of their local environmental can be used to improve SNe Iaas distance indicators. These correlations can be used to both reducethe dispersion in standardized brightnesses and correct existing biases.This proposal aims to analyze both global and local properties usingUV-to-optical photometry in order to understand the source of the SNastrophysical biases found so far, and to use that knowledge to developtools with which future high-redshift SN Ia surveys can correct or exploitthese correlations. The UV data necessary to break the degeneracy betweenstellar ages and dust extinction is only accessible from space, and inthe UV, only HST can provide the angular resolution necessary to study theenvironments of nearby smooth Hubble-flow SN Ia hosts on the kpc scale.

    To obtain reliable measurements of the environmental radionuclide activity using HPGe (High Purity Germanium) detectors, the knowledge of the absolute peak efficiency is required. This work presents a practical procedure for efficiency calibration of a coaxial n-type and a well-type HPGe detector using experimental and Monte Carlo simulations methods. The method was performed in an energy range from 40 to 1460 keV and it can be used for both, solid and liquid environmental samples. The calibration was initially verified measuring several reference materials provided by the IAEA (International Atomic Energy Agency). Finally, through the participation in two Proficiency Tests organized by IAEA for the members of the ALMERA network (Analytical Laboratories for the Measurement of Environmental Radioactivity) the validity of the developed procedure was confirmed. The validation also showed that measurement of {sup 226}Ra should be conducted using coaxial n-type HPGe detector in order to minimize the true coincidence summing effect. - Highlights: • An efficiency calibration for a coaxial and a well-type HPGe detector was performed. • The calibration was made using experimental and Monte Carlo simulations methods. • The procedure was verified measuring several reference materials provided by IAEA. • Calibrations were validated through the participation in 2 ALMERA Proficiency Tests.

    Pollution and viral infections could be associated with the incidence of type 1 diabetes mellitus. To look for associations between the temporal patterns of Type 1 Diabetes Mellitus (T1D) in infants younger than the age of 15 years, and environmental factors, such as air pollution and viruses. Data registries from hospitals, emergency services, and the Infantile Diabetes Foundation were reviewed, corresponding to children aged less than 15 years, who received their first insulin injection between 2000 and 2007. The incidence of type 1 diabetes was computed for each epidemiological week. Environmental ozone and particulate matter rates for each week were obtained from Environmental services. Rates of influenza and respiratory syncytial virus infections were obtained from the epidemiological department of the Ministry of Health. An ecological Bayesian Poisson regression model was fitted, introducing the covariates, lagged covariates and errors, to estimate the incidence by epidemiological week. Three factors were significant by the proposed model: particulate matter PPM 2.5 (relative risk (RR): 1.003) lagged by two weeks, influenza (RR: 0.1808) and RSV (RR: 1.021). Trends and seasonality were clearly controlled by these covariates, considering the epidemiological week as a counting period. These results show that environmental factors could be related to peaks of type 1 diabetes incidence.

    2013-11-01

    Full Text Available The present article deals with the idea of the “harmonious society,” which is at the core of contemporary social ideologies in the P. R. China. This concept is examined from three perspectives: the official state interpretations of the concept of harmony (he 和 or hexie 和諧, and the classical and Modern Confucian elucidations. The author concludes that official political interpretations from the P.R. China mainly follow Xunzi’s classical elaboration of this concept, which is in the legalist tradition and implies autocratic elements, whereas the philosophic interpretations written by the Taiwanese Modern Confucians generally elaborate the Mencian, i.e. the more egalitarian and democratic stream of classical Confucian thought.

    Full Text Available This paper offers an account of diachronic changes in nasal harmony in Mundurukú, a Tupian language from Brazil. It attempts to show that the Optimality Theory provides new ways of accounting for sound change, other than constraint re-ranking. A comparison of Mundurukú and Kuruaya's modern systems points out that the source system, Proto-Mundurukú, had similar properties to those currently observed in Kuruaya. In particular, nasal spread targets were voiced stops and sonorants, whereas voiceless obstruents were transparent. This system was developed into another in Pre-Mundurukú, because new contrasts were introduced in the language, turning obstruents into opaque segments, thus blocking nasalization. Formal OT account of both cases relies on restricting harmony constraints, as shown by the relative chronology that gave rise to Mundurukú's modern system. In addition, this study discusses the consequences of this change to synchronic grammar, and how it explains the process' irregularities.

    In this paper, opposition-based harmony search has been applied for the optimal design of linear phase FIR filters. RGA, PSO, and DE have also been adopted for the sake of comparison. The original harmony search algorithm is chosen as the parent one, and opposition-based approach is applied. During the initialization, randomly generated population of solutions is chosen, opposite solutions are also considered, and the fitter one is selected as a priori guess. In harmony memory, each such solution passes through memory consideration rule, pitch adjustment rule, and then opposition-based reinitialization generation jumping, which gives the optimum result corresponding to the least error fitness in multidimensional search space of FIR filter design. Incorporation of different control parameters in the basic HS algorithm results in the balancing of exploration and exploitation of search space. Low pass, high pass, band pass, and band stop FIR filters are designed with the proposed OHS and other aforementioned algorithms individually for comparative optimization performance. A comparison of simulation results reveals the optimization efficacy of the OHS over the other optimization techniques for the solution of the multimodal, nondifferentiable, nonlinear, and constrained FIR filter design problems.

  17. A Dynamical Model of Pitch Memory Provides an Improved Basis for Implied Harmony Estimation

    2017-01-01

    Tonal melody can imply vertical harmony through a sequence of tones. Current methods for automatic chord estimation commonly use chroma-based features extracted from audio signals. However, the implied harmony of unaccompanied melodies can be difficult to estimate on the basis of chroma content in the presence of frequent nonchord tones. Here we present a novel approach to automatic chord estimation based on the human perception of pitch sequences. We use cohesion and inhibition between pitches in auditory short-term memory to differentiate chord tones and nonchord tones in tonal melodies. We model short-term pitch memory as a gradient frequency neural network, which is a biologically realistic model of auditory neural processing. The model is a dynamical system consisting of a network of tonotopically tuned nonlinear oscillators driven by audio signals. The oscillators interact with each other through nonlinear resonance and lateral inhibition, and the pattern of oscillatory traces emerging from the interactions is taken as a measure of pitch salience. We test the model with a collection of unaccompanied tonal melodies to evaluate it as a feature extractor for chord estimation. We show that chord tones are selectively enhanced in the response of the model, thereby increasing the accuracy of implied harmony estimation. We also find that, like other existing features for chord estimation, the performance of the model can be improved by using segmented input signals. We discuss possible ways to expand the present model into a full chord estimation system within the dynamical systems framework. PMID:28522983

    Full Text Available The article presents an outlook on the issue of a personality’s harmonious development which is extremely complex and versatile. The opportunity of developing the personality needs a comprehensive understanding of children’s psychology at all stages of maturation, from kindergarten to the highest educational establishments. In the 20th century A. Lunacharskyi, S. Shatskyi, A. Makarenko contributed to the development of the theory of harmonious upbringing and implementing this theory into life. Similar ideas as for realization of a personality’s harmonious development were disclosed in works by V. Sukhomlynskyi, P. Atutov and M. Skatkin. The aim of the article is to make an emphasis on the discipline of dance education cycle in the context of a harmonious personality; to identify effective combination of music and dancing in fostering emotional, creative and aesthetic components that contribute to the harmonious development of the young generation. The main focus of the author in this article is made on the intellectual, moral and physical growth of pupils which, in her opinion, is the fundamental way of revealing the creative potential of a personality. The author focuses her attention on the well-balanced development of both, the gifted children, and those who are not sufficiently advanced in the physical and creative aspects. The article defines the dominance of dance creativity while forming children’s emotional-sensory sphere and their physiological and mental health. The analysis of choreographic communication is made not only with music, but also with graphic, musical, theater and esthetic culture of children. It is shown that the art of dance can`t exist without music. So the success of teaching the choreography depends on the quality of the tandem of a dance teacher and an accompanist. The success of the children in this creative initiative largely depends on how competently, clearly and emotionally the accompanist feels a

    In order to improve environmental condition such as humidity and airflow in living spaces, a whole ceiling-type air conditioner is proposed. This novel air conditioner exhaust dispersed airflow from the whole ceiling by using a 3-dimensional knit fabric. The purpose of this paper is to reveal the effects when controlling humidity and airflow using the whole ceiling-type air conditioner compared to a commercialized concentrated exhaust air conditioner (normal-type air conditioner) under the same temperature. Salivary {alpha}-amylase activity (SAA) was used as an index of sympathetic nervous activity. An acute experiment for a 15 min period was conducted using 12 healthy young female adults. No significant differences in room and skin temperatures were observed between the whole ceiling-type air conditioner and the normal-type air conditioner. The whole ceiling-type air conditioner showed 11.1% lower humidity than the normal-type air conditioner. The whole ceiling-type air conditioner showed one-thirteenth the airflow of the normal-type air conditioner. As a result, the PMV of the whole ceiling-type air conditioner was more comfortable level than the normal one. Moreover, subjective evaluation questionnaire revealed a significant difference was observed in wind perception (windy). The SAA of subjects under the whole ceiling-type air conditioner showed significantly low values compared with the normal-type air conditioner. It was found that the subject's sympathetic nervous activity has been inactivated under the conditions of the whole ceiling-type air conditioner. Thus, it was revealed that the whole ceiling-type air conditioner provides a more comfortable air environment by reducing physical stimulations to humans. (author)

    Within a metacommunity, both environmental and spatial processes regulate variation in local community structure. The strength of these processes may vary depending on species traits (e.g., dispersal mode) or the characteristics of the regions studied (e.g., spatial extent, environmental heterogeneity). We studied the metacommunity structuring of three groups of stream macroinvertebrates differing in their overland dispersal mode (passive dispersers with aquatic adults; passive dispersers wit...

  9. The effect of charging time on the comparative environmental performance of different vehicle types

    2016-01-01

    Highlights: • The environmental performance of a PHEV and equivalent ICE were analysed using LCA. • Charging behaviour and electricity profiles of Australia’s NEM grid were included. • A methodology to model the marginal electricity supply mix was developed. • PHEVs charged from the NEM present greenhouse gas benefits. • Burden shifts towards other environmental indicators may occur, but are uncertain. - Abstract: This study combines electricity supply mix profiles and observed charging behaviour to compare the environmental performance of a petrol-hybrid electric vehicle (PHEV) with a class-equivalent internal combustion engine (ICE) vehicle over the full life cycle. Environmental performance is compared using a suite of indicators across the life cycle, accounting for both marginal and average electricity supply mixes for Australia’s National Energy Market (NEM) grid. The use of average emission factors for the NEM grid can serve as a good proxy for accounting charging behaviour, provided that there is a strong correlation between the time of charging and total electricity demand. Compared with an equivalent ICE, PHEVs charged from Australia’s NEM can reduce greenhouse gas emissions over the life cycle. Potential burden shifts towards acidification, eutrophication and human toxicity impacts may occur, but these impacts are uncertain due to modelling limitations. This study has the potential to inform both short and long term forecasts of the environmental impacts associated with EV deployment in Australia and provides a better understanding the temporal variations in emissions associated with electricity use in the short term.

    The development of environmental microsensor techniques is a revolutionary advance in the measurement of both absolute levels and changes in chemical species in the field of environmental engineered and natural systems. The tiny tip (5–15 µm diameter) of microsensors makes them very attractive experimental tools for direct measurements of the chemical species of interest inside biological samples (e.g., biofilm, flocs). Microelectrodes fabricated from pulled micropipettes (e.g., dissolved oxygen, oxidation–reduction potential, ion-selective microelectrode) have contributed to greater understanding of biological mechanisms for decades using microscopic monitoring, and currently microelectromechanical system (MEMS) microfabrication technologies are being successfully applied to fabricate multi-analyte sensor systems for in situ monitoring. This review focuses on needle-type environmental microsensor technology, including microelectrodes and multi-analyte MEMS sensor arrays. Design, construction and applications to biofilm research of these sensors are described. Practical methods for biofilm microprofile measurements are presented and several in situ applications for a biofilm study are highlighted. Ultimately, the developed needle-type microsensors combined with molecular biotechnology (such as microscopic observation with fluorescent probes) show the tremendous promise of micro-environmental sensor technology.

    Recent studies have suggested the importance of the neighborhood environment in determining the specific type of physical activity. However, few studies on this topic have been undertaken in Japan. This study examined the association of three types of physical activity and their associations with individual and neighborhood environmental factors among middle-aged and elderly Japanese. Participants were 2,449 adults aged 40-69 living in Fujisawa city who had undergone health checkups and responded to our survey by mail. Individual factors, the International Physical Activity Questionnaire (long form), and its environmental module acted as inputs to the study. The adjusted odds ratios (ORs) of high levels of moderate-to-vigorous intensity leisure-time physical activity (LTPA), walking for active recreation, and transportation were calculated in relation to individual and neighborhood environmental factors through multiple logistic regression models. Not working and good self-rated health were significantly associated with a higher level of each physical activity outcome. According to the adjusted ORs, higher educational attainment, higher economic status, good access to exercise facilities, and owning motor vehicles were associated with longer LTPA time. However, different sets of factors were associated with longer walking times for recreation and transportation. The results suggest that diverse individual and neighborhood environmental characteristics are associated with different physical activity outcomes. Therefore, customizing environments to become activity-friendly is necessary to increase physical activity effectively among middle-aged and elderly Japanese.

    Coal is one of the most important sources of energy. Its worldwide use will continue to expand during the next several decades, particularly in rapidly developing countries such as China and India. Unfortunately, coal use may bring with it environmental and human health costs. Many of the environmental and health problems attributed to coal combustion are due to mobilization of potentially toxic elements. Some of these problems could be minimized or even avoided if comprehensive databases containing appropriate coal quality information were available to decision makers so that informed decisions could be made regarding coal use. Among the coal quality parameters that should be included in these databases are: C, H, N, O, pyritic sulfur, organic sulfur, major, minor, and trace element concentrations, modes of occurrence of environmentally sensitive elements, cleanability, mineralogy, organic chemistry, petrography, and leachability.Coal is one of the most important sources of energy.

    Domestic violence (DV) affects over a third of Chinese women in a relationship. Focusing on ethnographic data from six staff members and six DV survivors at a rural, state-affiliated women's center in China in 2010, this article relies on Henrietta Moore's notion of the poststructuralist gendered subject to examine how the staff draw on discourses about gender and social harmony in persuading women to stay in their marriages, rather than on human rights discourses that emphasize survivor safety. It shows that DV survivors are frequently sent back to dangerous homes where their health is placed at risk.

  18. Neurobiological foundations for the theory of harmony in western tonal music.

    Basic principles of the theory of harmony reflect physiological and anatomical properties of the auditory nervous system and related cognitive systems. This hypothesis is motivated by observations from several different disciplines, including ethnomusicology, developmental psychology, and animal behavior. Over the past several years, we and our colleagues have been investigating the vertical dimension of harmony from the perspective of neurobiology using physiological, psychoacoustic, and neurological methods. Properties of the auditory system that govern harmony perception include (1) the capacity of peripheral auditory neurons to encode temporal regularities in acoustic fine structure and (2) the differential tuning of many neurons throughout the auditory system to a narrow range of frequencies in the audible spectrum. Biologically determined limits on these properties constrain the range of notes used in music throughout the world and the way notes are combined to form intervals and chords in popular Western music. When a harmonic interval is played, neurons throughout the auditory system that are sensitive to one or more frequencies (partials) contained in the interval respond by firing action potentials. For consonant intervals, the fine timing of auditory nerve fiber responses contains strong representations of harmonically related pitches implied by the interval (e.g., Rameau's fundamental bass) in addition to the pitches of notes actually present in the interval. Moreover, all or most of the partials can be resolved by finely tuned neurons throughout the auditory system. By contrast, dissonant intervals evoke auditory nerve fiber activity that does not contain strong representations of constituent notes or related bass notes. Furthermore, many partials are too close together to be resolved. Consequently, they interfere with one another, cause coarse fluctuations in the firing of peripheral and central auditory neurons, and give rise to perception of

    In various paradigms of modern neurosciences of music, experts of Western classical music have displayed superior brain architecture when compared with individuals without explicit training in music. In this paper, we show that chord violations embedded in musical cadences were neurally processed in a facilitated manner also by musicians trained in Finnish folk music. This result, obtained by using early right anterior negativity (ERAN) as an index of harmony processing, suggests that tonal processing is advanced in folk musicians by their long-term exposure to both Western and non-Western music. © 2012 New York Academy of Sciences.

    2013-01-01

    Full Text Available A hybrid metaheuristic approach by hybridizing harmony search (HS and firefly algorithm (FA, namely, HS/FA, is proposed to solve function optimization. In HS/FA, the exploration of HS and the exploitation of FA are fully exerted, so HS/FA has a faster convergence speed than HS and FA. Also, top fireflies scheme is introduced to reduce running time, and HS is utilized to mutate between fireflies when updating fireflies. The HS/FA method is verified by various benchmarks. From the experiments, the implementation of HS/FA is better than the standard FA and other eight optimization methods.

    As known, tuned mass dampers (TMDs) are added to mechanical systems in order to obtain a good vibration damping. The main aim is to reduce the maximum amplitude at the resonance state. In this study, a metaheuristic algorithm called harmony search employed for the optimum design of TMDs. As the optimization objective, the transfer function of the acceleration of the system with respect to ground acceleration was minimized. The numerical trails were conducted for 4 single degree of freedom systems and the results were compared with classical methods. As a conclusion, the proposed method is feasible and more effective than the other documented methods.

    Metaheuristic algorithms are effective in the design of an intelligent system. These algorithms are widely applied to solve complex optimization problems, including image processing, big data analytics, language processing, pattern recognition and others. This paper presents a performance comparison of three meta-heuristic algorithms, namely Harmony Search, Differential Evolution, and Particle Swarm Optimization. These algorithms are originated altogether from different fields of meta-heuristics yet share a common objective. The standard benchmark functions are used for the simulation. Statistical tests are conducted to derive a conclusion on the performance. The key motivation to conduct this research is to categorize the computational capabilities, which might be useful to the researchers.

    The first results of a joint CEA/CNEN neutron propagation program conducted on the source reactors HARMONIE and TAPIRO are presented. In both cases, a buffer zone representative of the blanket of a commercial fast power reactor is interposed between the source reactor and the medium in which neutron propagation is measured. This buffer zone provides a realistic source spectrum to be propagated. Experimental results are compared to older results obtained without the buffer zone. The effect of the source spectrum on neutron propagation is discussed, as well as the coherence of the results obtained with the two installations

    Full Text Available Migraine can be triggered by many factors such as stress, sleep, fasting and environmental causes. There are few studies that evaluated migraine trigger factors in the adolescent population. Methods: A total of 100 participants from 10 to 19 years were subjected to a detailed headache questionnaire, with demographic and clinical data, and a headache diary including trigger factors during a two-month period was asked. Results: Fifty of the participants exhibited chronic migraine and the other 50 participants demonstrated episodic migraine. The most common group of trigger factors reported was the environmental one, mainly sun/clarity, followed by hot weather and the smell of perfume. Conclusions: Ninety-one percent of children and adolescents with migraine reported a trigger factor precipitating the migraine attack.

    Full Text Available BACKGROUND: Human cryptococcal infections have been associated with bird droppings as a likely source of infection. Studies toward the local and global epidemiology of Cryptococcus spp. have been hampered by the lack of rapid, discriminatory, and exchangeable molecular typing methods. METHODOLOGY/PRINCIPAL FINDINGS: We selected nine microsatellite markers for high-resolution fingerprinting from the genome of C. neoformans var. grubii. This panel of markers was applied to a collection of clinical (n = 122 and environmental (n = 68; from pigeon guano C. neoformans var. grubii isolates from Cuba. All markers proved to be polymorphic. The average number of alleles per marker was 9 (range 5-51. A total of 104 genotypes could be distinguished. The discriminatory power of this panel of markers was 0.993. Multiple clusters of related genotypes could be discriminated that differed in only one or two microsatellite markers. These clusters were assigned as microsatellite complexes. The majority of environmental isolates (>70% fell into 1 microsatellite complex containing only few clinical isolates (49 environmental versus 2 clinical. Clinical isolates were segregated over multiple microsatellite complexes. CONCLUSIONS/SIGNIFICANCE: A large genotypic variation exists in C. neoformans var. grubii. The genotypic segregation between clinical and environmental isolates from pigeon guano suggests additional source(s of human cryptococcal infections. The selected panel of microsatellite markers is an excellent tool to study the epidemiology of C. neoformans var. grubii.

  7. Learning and liking of melody and harmony: further studies in artificial grammar learning.

    2012-10-01

    Much of what we know and love about music is based on implicitly acquired mental representations of musical pitches and the relationships between them. While previous studies have shown that these mental representations of music can be acquired rapidly and can influence preference, it is still unclear which aspects of music influence learning and preference formation. This article reports two experiments that use an artificial musical system to examine two questions: (1) which aspects of music matter most for learning, and (2) which aspects of music matter most for preference formation. Two aspects of music are tested: melody and harmony. In Experiment 1 we tested the learning and liking of a new musical system that is manipulated melodically so that only some of the possible conditional probabilities between successive notes are presented. In Experiment 2 we administered the same tests for learning and liking, but we used a musical system that is manipulated harmonically to eliminate the property of harmonic whole-integer ratios between pitches. Results show that disrupting melody (Experiment 1) disabled the learning of music without disrupting preference formation, whereas disrupting harmony (Experiment 2) does not affect learning and memory but disrupts preference formation. Results point to a possible dissociation between learning and preference in musical knowledge. Copyright © 2012 Cognitive Science Society, Inc.

  8. An improved harmony search algorithm for synchronization of discrete-time chaotic systems

    Santos Coelho, Leandro dos; Andrade Bernert, Diego Luis de

    2009-01-01

    The harmony search (HS) algorithm is a recently developed meta-heuristic algorithm, and has been very successful in a wide variety of optimization problems. HS was conceptualized using an analogy with music improvisation process where music players improvise the pitches of their instruments to obtain better harmony. The HS algorithm does not require initial values and uses a random search instead of a gradient search, so derivative information is unnecessary. Furthermore, the HS algorithm is simple in concept, few in parameters, easy in implementation, imposes fewer mathematical requirements, and does not require initial value settings of the decision variables. In recent years, the investigation of synchronization and control problem for discrete chaotic systems has attracted much attention, and many possible applications. The tuning of a proportional-integral-derivative (PID) controller based on an improved HS (IHS) algorithm for synchronization of two identical discrete chaotic systems subject the different initial conditions is investigated in this paper. Simulation results of the IHS to determine the PID parameters to synchronization of two Henon chaotic systems are compared with other HS approaches including classical HS and global-best HS. Numerical results reveal that the proposed IHS method is a powerful search and controller design optimization tool for synchronization of chaotic systems.

  9. Urban-Water Harmony model to evaluate the urban water management.

    Water resources in many urban areas are under enormous stress due to large-scale urban expansion and population explosion. The decision-makers are often faced with the dilemma of either maintaining high economic growth or protecting water resources and the environment. Simple criteria of water supply and drainage do not reflect the requirement of integrated urban water management. The Urban-Water Harmony (UWH) model is based on the concept of harmony and offers a more integrated approach to urban water management. This model calculates four dimensions, namely urban development, urban water services, water-society coordination, and water environment coordination. And the Analytic Hierarchy Process has been used to determine the indices weights. We applied the UWH model to Beijing, China for an 11-year assessment. Our findings show that, despite the severe stress inherent in rapid development and water shortage, the urban water relationship of Beijing is generally evolving in a positive way. The social-economic factors such as the water recycling technologies contribute a lot to this change. The UWH evaluation can provide a reasonable analysis approach to combine various urban and water indices to produce an integrated and comparable evaluation index. This, in turn, enables more effective water management in decision-making processes.

  10. A Method for Estimating View Transformations from Image Correspondences Based on the Harmony Search Algorithm

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In this paper, a new method for robustly estimating multiple view relations from point correspondences is presented. The approach combines the popular random sampling consensus (RANSAC algorithm and the evolutionary method harmony search (HS. With this combination, the proposed method adopts a different sampling strategy than RANSAC to generate putative solutions. Under the new mechanism, at each iteration, new candidate solutions are built taking into account the quality of the models generated by previous candidate solutions, rather than purely random as it is the case of RANSAC. The rules for the generation of candidate solutions (samples are motivated by the improvisation process that occurs when a musician searches for a better state of harmony. As a result, the proposed approach can substantially reduce the number of iterations still preserving the robust capabilities of RANSAC. The method is generic and its use is illustrated by the estimation of homographies, considering synthetic and real images. Additionally, in order to demonstrate the performance of the proposed approach within a real engineering application, it is employed to solve the problem of position estimation in a humanoid robot. Experimental results validate the efficiency of the proposed method in terms of accuracy, speed, and robustness.

    2018-12-01

    Full Text Available Understanding of the existence of various religious receptions in culture gives a great opportunity for the building and nurturance of harmony among religious followers and for the creating of solidarities in the society. This article uncovers receptions of religious aspects (ultimate truth aspect/god, cosmological aspect and religious ritual aspect in the cultural products of Radin Lambat, a folktale from Lampung. The article is based on the texts of Radin Lambat folktale, interviews, and other literary sources about Lampung cultures. Religious receptions as shown in Radin Lambat folktale indicate the preservation of past beliefs, coupled with the gentle addition and inclusion of Islamic teachings, to create harmonization between religion and tradition through folktale. This shows that Islam in the societies of Lampung is Islam that values cultures through the processes of gradual and varied receptions. This article is expected to add evidence to related sources about the concepts and practices of harmony among religious followers in Indonesia in local tradition, and the addition to the range of the rare religious-cultural reception studies of Lampung society

    This study proposes a groundwater resources management model in which the solution is performed through a combined simulation-optimization model. A modular three-dimensional finite difference groundwater flow model, MODFLOW is used as the simulation model. This model is then combined with a Harmony Search (HS) optimization algorithm which is based on the musical process of searching for a perfect state of harmony. The performance of the proposed HS based management model is tested on three separate groundwater management problems: (i) maximization of total pumping from an aquifer (steady-state); (ii) minimization of the total pumping cost to satisfy the given demand (steady-state); and (iii) minimization of the pumping cost to satisfy the given demand for multiple management periods (transient). The sensitivity of HS algorithm is evaluated by performing a sensitivity analysis which aims to determine the impact of related solution parameters on convergence behavior. The results show that HS yields nearly same or better solutions than the previous solution methods and may be used to solve management problems in groundwater modeling.

    Many studies have revealed shared music-language processing resources by finding an influence of music harmony manipulations on concurrent language processing. However, the nature of the shared resources has remained ambiguous. They have been argued to be syntax specific and thus due to shared syntactic integration resources. An alternative view regards them as related to general attention and, thus, not specific to syntax. The present experiments evaluated these accounts by investigating the influence of language on music. Participants were asked to provide closure judgements on harmonic sequences in order to assess the appropriateness of sequence endings. At the same time participants read syntactic garden-path sentences. Closure judgements revealed a change in harmonic processing as the result of reading a syntactically challenging word. We found no influence of an arithmetic control manipulation (experiment 1) or semantic garden-path sentences (experiment 2). Our results provide behavioural evidence for a specific influence of linguistic syntax processing on musical harmony judgements. A closer look reveals that the shared resources appear to be needed to hold a harmonic key online in some form of syntactic working memory or unification workspace related to the integration of chords and words. Overall, our results support the syntax specificity of shared music-language processing resources.

  14. Sequential fault diagnosis for mechatronics system using diagnostic hybrid bond graph and composite harmony search

    2015-12-01

    Full Text Available This article proposes a sequential fault diagnosis method to handle asynchronous distinct faults using diagnostic hybrid bond graph and composite harmony search. The faults under consideration include fault mode, abrupt fault, and intermittent fault. The faults can occur in different time instances, which add to the difficulty of decision making for fault diagnosis. This is because the earlier occurred fault can exhibit fault symptom which masks the fault symptom of latter occurred fault. In order to solve this problem, a sequential identification algorithm is developed in which the identification task is reactivated based on two conditions. The first condition is that the latter occurred fault has at least one inconsistent coherence vector element which is consistent in coherence vector of the earlier occurred fault, and the second condition is that the existing fault coherence vector has the ability to hide other faults and the second-level residual exceeds the threshold. A new composite harmony search which is capable of handling continuous variables and binary variables simultaneously is proposed for identification purpose. Experiments on a mobile robot system are conducted to assess the proposed sequential fault diagnosis algorithm.

  15. Optimality theory and historical phonology: an example from nasal harmony in mundurukú

    2013-01-01

    Full Text Available This paper offers an account of diachronic changes in nasal harmony in Mundurukú, a Tupian language from Brazil. It attempts to show that the Optimality Theory provides new ways of accounting for sound change, other than constraint re-ranking. A comparison of Mundurukú and Kuruaya’s modern systems points out that the source system, Proto-Mundurukú, had similar properties to those currently observed in Kuruaya. In particular, nasal spread targets were voiced stops and sonorants, whereas voiceless obstruents were transparent. This system was developed into another in Pre-Mundurukú, because new contrasts were introduced in the language, turning obstruents into opaque segments, thus blocking nasalization. Formal OT account of both cases relies on restricting harmony constraints, as shown by the relative chronology that gave rise to Mundurukú’s modern system. In addition, this study discusses the consequences of this change to synchronic grammar, and how it explains the process’ irregularities.

    There has been significant progress in understanding the role of neurotransmitters in normal and pathologic brain function. However, preclinical trials aimed at improving therapeutic interventions do not take advantage of real-time in vivo neurochemical changes in dynamic brain processes such as disease progression and response to pharmacologic, cognitive, behavioral, and neuromodulation therapies. This is due in part to a lack of flexible research tools that allow in vivo measurement of the dynamic changes in brain chemistry. Here, we present a research platform, WINCS Harmoni, which can measure in vivo neurochemical activity simultaneously across multiple anatomical targets to study normal and pathologic brain function. In addition, WINCS Harmoni can provide real-time neurochemical feedback for closed-loop control of neurochemical levels via its synchronized stimulation and neurochemical sensing capabilities. We demonstrate these and other key features of this platform in non-human primate, swine, and rodent models of deep brain stimulation (DBS). Ultimately, systems like the one described here will improve our understanding of the dynamics of brain physiology in the context of neurologic disease and therapeutic interventions, which may lead to the development of precision medicine and personalized therapies for optimal therapeutic efficacy.

    2012-10-01

    Full Text Available GMS (Generator Maintenance Scheduling ranks very high in decision making of power generation management. Generators maintenance schedule decides the time period of maintenance tasks and a reliable reserve margin is also maintained during this time period. In this paper, a comparison of GA (Genetic Algorithm and HS (Harmony Search algorithm is presented to solve generators maintenance scheduling problem for WAPDA (Water And Power Development Authority Pakistan. GA is a search procedure, which is used in search problems to compute exact and optimized solution. GA is considered as global search heuristic technique. HS algorithm is quite efficient, because the convergence rate of this algorithm is very fast. HS algorithm is based on the concept of music improvisation process of searching for a perfect state of harmony. The two algorithms generate feasible and optimal solutions and overcome the limitations of the conventional methods including extensive computational effort, which increases exponentially as the size of the problem increases. The proposed methods are tested, validated and compared on the WAPDA electric system.

    In well-being research the term happiness is often used as synonymous with life satisfaction. However, little is known about lay people's understanding of happiness. Building on the available literature, this study explored lay definitions of happiness across nations and cultural dimensions, analyzing their components and relationship with participants' demographic features. Participants were 2799 adults (age range = 30–60, 50% women) living in urban areas of Argentina, Brazil, Croatia, Hungary, India, Italy, Mexico, New Zealand, Norway, Portugal, South Africa, and United States. They completed the Eudaimonic and Hedonic Happiness Investigation (EHHI), reporting, among other information, their own definition of happiness. Answers comprised definitions referring to a broad range of life domains, covering both the contextual-social sphere and the psychological sphere. Across countries and with little variation by age and gender, inner harmony predominated among psychological definitions, and family and social relationships among contextual definitions. Whereas relationships are widely acknowledged as basic happiness components, inner harmony is substantially neglected. Nevertheless, its cross-national primacy, together with relations, is consistent with the view of an ontological interconnectedness characterizing living systems, shared by several conceptual frameworks across disciplines and cultures. At the methodological level, these findings suggest the potential of a bottom-up, mixed method approach to contextualize psychological dimensions within culture and lay understanding. PMID:26858677

    Full Text Available Returning to medieval spirituality seems to be a common feature of the artistic currents, claimed by romanticism: expressionism, abstract expressionism or neo-expressionism. In romanticism the aspiration toward the absolute was obviously. In expressionism the place edicated to the divinity is found to be empty, and art becomes a cry of despair facing the solitude. Abstract expressionism does not even try to aim for transcendence, but it does probe the interiority, subjectivity and reaction of the human being in the midst of being. However, there are artists belonging to the abstract expressionism who express in their art the harmony of the human being within the cosmos. An example is the art of J. Pollock. It is an art for which not only the artistic image, but also the technique, the dripping, and the means of working become expressions of the cosmic harmony. It is something alike a part of science (F.Capra or the medieval mysticism where we find the same need of communion with nature, a spiritualization of the world, as the first step on the path towards divinity.

    Full Text Available The development of green technology in the construction industry since 10 years ago is something to be proud of Malaysia. Several alternative geopolymer materials were invented in Malaysia such as fly ash, POFA, kaolin, metakaolin, and dolomite based geopolymer materials to achieve sustainable development especially in the building and construction sector. Those alternative materials are very important to replace the application of OPC, which is said to be the main cause of global warming. A review on the content of the chemical differences with the environmental impact resulting from the production of geopolymer is carried out in this study. In conclusion, fly ash based geopolymer material showed the best performance in terms of aluminosilicate content and also it is the best practice in the environmental protection applications for the moment. However, when compared with the OPC, fly ash geopolymer concrete was still able to reduce the effects of global warming potentials, but it is rather gave a negative impact on some aspects of the environment such as abiotic depletions, human toxicity, freshwater ecotoxicity, terrestrial ecotoxicity and acidification.

    2017-08-07

    The aim was to compare the presence of environmental barriers to participation and facilitators for assistive technology (AT) use and study the relation between barriers and AT use in three different AT devices. A cross-sectional survey was conducted. Inclusion criteria were ≥one year of experience as a user of myoelectric prosthesis (MEP), powered mobility device (PMD), or assistive technology for cognition (ATC) and age 20-90 years. Overall, 156 participants answered the Swedish version of the Craig Hospital Inventory of Environmental Factors and a study-specific questionnaire on facilitating factors. Non-parametric tests were used for comparisons. Barriers to participation were lowest in MEP users (md=0.12; p>0.001), and highest in ATC users (md=1.56; p>0.001) with the least support for AT use (p>0.001 - p=0.048). A positive correlation between fewer barriers and higher use of MEP was seen (r=0.30, p=0.038). The greatest barriers to participation were Natural environment, Surroundings and Information, and the most support came from relatives and professionals. Support, training and education are vital in the use of AT. These factors may lead to a more sustained and prolonged use of AT and may enable increased participation. Future research should focus on interventions that meet the needs of people with cognitive disabilities.

    Full Text Available This study explores the thermal design of shell and tube heat exchangers by using Improved Intelligent Tuned Harmony Search (I-ITHS algorithm. Intelligent Tuned Harmony Search (ITHS is an upgraded version of harmony search algorithm which has an advantage of deciding intensification and diversification processes by applying proper pitch adjusting strategy. In this study, we aim to improve the search capacity of ITHS algorithm by utilizing chaotic sequences instead of uniformly distributed random numbers and applying alternative search strategies inspired by Artificial Bee Colony algorithm and Opposition Based Learning on promising areas (best solutions. Design variables including baffle spacing, shell diameter, tube outer diameter and number of tube passes are used to minimize total cost of heat exchanger that incorporates capital investment and the sum of discounted annual energy expenditures related to pumping and heat exchanger area. Results show that I-ITHS can be utilized in optimizing shell and tube heat exchangers.

    Environmental radioactivity and chemical composition of bee honey varies with the surrounding environment (major floral and soil contamination), which reflects the nutritional value of honey. 23SU, 232Th, 40K, >37Cs, major elements Na, K, Mg and Cl and trace elements Mn, Fe, Zn, F, I, Cu, Co, Ni and Sr as well as toxic elements Cd and Pb -were all determined in different types of bee honey, which include non-floral honey with artificial feeding (syrup-feed honey) and mono-floral honeys (clover honey or sesame honey or orange honey). These elements were also determined in the bee feeds, which include flowers (clover, sesame and orange) and syrup. The results revealed that of all types of honeys and syrup-feed honey exhibited higher natural radioactivity and higher concentrations ofNa, K, Mg, Cl, oMn, Fe, Co, Cd and Pb than in the other honeys. Orange honey contained the lowest natural radioactivity and element concentrations. Clover honey had the lowest toxic element Cd and Pb concentrations (0.02 and 4.2/xg/g, respectively) while sesame honey contained the highest levels of Cd and F (0.7 and 12.9 /ig/g, respectively). Statistical analysis revealed significant correlation between honey and the feed (R= 0.745 to 0.921). Environmental radioactivity and element concentrations in the honey under study were in the safety baseline levels for human consumption

    This paper aims to evaluate the environmental impacts of valorizing food waste for three types of energy use, namely electricity and heat, city gas, and biogas fuel as a petrol, diesel, and liquefied petroleum gas substitute for vehicle use, with reference to the Hong Kong scenario. The life cycle based environmental assessment is conducted from bin-to-cradle system boundary via SimaPro 7.2.4 with ReCiPe 1.04. All of the inventory data of included processes is based on reports of government and industrial sectors. The results show that biogas fuel as a petrol substitute for vehicle use is advantageous over other types of energy use in regard to human health and ecosystems, and it is also the best considering the government's future emission reduction targets set out for the power and transport sectors in Hong Kong. By turning 1080 tonnes per day of food waste into biogas vehicle fuel as petrol substitute, it reduces 1.9% of greenhouse gas emissions in the transport sectors, which results a larger decrease of GHG emissions than the achieved mitigation in Hong Kong from 2005 to 2010.

    Environmental surveillance of poliovirus on sewage has been conducted in Shandong Province, China since 2008. A type 2 vaccine-derived poliovirus (VDPV) with 7 mutations in VP1 coding region was isolated from the sewage collected in the city of Jinan in December 2012. The complete genome sequencing analysis of this isolate revealed 25 nucleotide substitutions, 7 of which resulted in amino acid alteration. No evidence of recombination with other poliovirus serotypes was observed. The virus did not lose temperature sensitive phenotype at 40°C. An estimation based on the evolution rate of the P1 coding region suggested that evolution time of this strain might be 160-176 days. VP1 sequence analysis revealed that this VDPV strain is of no close relationship with other local type 2 polioviruses (n=66) from sewage collected between May 2012 and June 2013, suggesting the lack of its circulation in the local population. The person who excreted the virus was not known and no closely related virus was isolated in local population via acute flaccid paralysis surveillance. By far this is the first report of VDPV isolated from sewage in China, and these results underscore the value of environmental surveillance in the polio surveillance system even in countries with high rates of OPV coverage.

    An environmental freshwater bacterial isolate, DM104, appearing as Shigella-like colonies on selective agar plates was found to show strong and specific serological cross-reactivity with Shigella dysenteriae type 4. Biochemical identification according to the analytical profile index, molecular serotyping by restriction of the amplified O-antigen gene cluster (rfb-RFLP), together with phylogenetic analysis of the 16S rRNA gene and multi-locus sequence analysis, identified the isolate as Escherichia albertii. rfb-RFLP of DM104, revealed a profile different from that of S. dysenteriae type 4. However, western blot analysis of extracted lipopolysaccharides demonstrated strong cross-reactivity with S. dysenteriae type 4 using specific monovalent antisera and a lipopolysaccharide gel banding profile similar to that of S. dysenteriae type 4. The observed O-antigen cross-reaction between an E. albertii isolate and S. dysenteriae extends our knowledge of the extent of O-antigen cross-reaction within the Escherichia/Shigella group of organisms, and offers the possibility of using DM104 and similar cross-reacting strains as shigellosis vaccine candidates.

    Seon-Mi Kim

    2017-11-01

    Full Text Available Carbonate-type macrodiols synthesized by base-catalyzed polycondensation of co-diols and dimethyl carbonate as an environmentally-friendly route were subsequently utilized for the preparation of transparent and self-healable thermoplastic polyurethanes (TPUs containing a carbonate-type soft segment. Three types of macrodiols, obtained from mono, dual and triple diol-monomers for target molecular weights of 1 and 1.5 kg mol−1, were analyzed by 1H NMR integration and the OH titration value. Colorless transparent macrodiols in a liquid state at a room temperature of 20 °C were obtained, except the macrodiol from mono 1,6-hexanediol. Before TPU synthesis, macrodiols require pH neutralization to prevent gelation. TPUs synthesized by a solution pre-polymer method with 4,4′-methylene(bisphenyl isocyanate and 1,4-butanediol as a chain extender exhibited moderate molecular weights, good transparencies and robust mechanical properties. Especially, the incorporation of 3-methyl-1,5-pentanediol within carbonate-type macrodiols enhanced the transparency of the resultant TPUs by decreasing the degree of microphase separation evidenced by ATR-FTIR and DSC. Interestingly, packing density of hard segments and the degree of microphase separation determined the self-healing efficiency of TPUs, which showed good performances in the case of sourced macrodiols from triple diol-monomers.

    2014-10-01

    Full Text Available The aim of the investigation was to estimate factors responsible for sustaining riverine communities in stream sections with various bank regulation systems. The research were conducted on Porebianka stream in the Polish Western Carpathians, where 10 different types of river regulations were chosen for the analysis (strong incision without alluvial deposits, redeposition with sand and gravel banks, concrete revetment walls along the banks, channel with banks lined with rip-rap and reference unmanaged cross- section. We conclude that the carabid beetles assemblages of the studied river sections respond mainly to hydraulic parameters of the stream. Elimination of frequent natural bank inundation (due to the regulations of the banks is the main factor responsible for the impoverishment and extinction of riverine communities.

    1997-01-01

    High resolution X-ray images of three early type galaxies observed with the ROSAT HRI are presented. Data for NGC 1553 and NGC 5846 indicate that the emission is highly irregular, with interesting features on scales from a few arcsec to a few arcmin. The gas temperatures also vary both with the galactocentric radius and in correspondence to regions of higher emission and denser material. Strikingly similar features are observed in the X-ray and H(alpha) morphologies of NGC 1553 and NGC 5846, while smoother, more regular isophotes are observed in NGC 4649 at both wavelengths. A connection between these two kinds of emission therefore seems likely. In the light of our observations we discuss possible scenarios that can and account for the connection between X-ray and H(alpha) emissions.

    2017-01-01

    Full Text Available To solve problems such as the high cost of microgrids (MGs, balance between supply and demand, stability of system operation, and optimizing the MG planning model, the energy storage system (ESS and harmony search algorithm (HSA are proposed. First, the conventional MG planning optimization model is constructed and the constraint conditions are defined: the supply and demand balance and reserve requirements. Second, an ESS is integrated into the optimal model of MG planning. The model with an ESS can solve and identify parameters such as the optimal power, optimal capacity, and optimal installation year. Third, the convergence speed and robustness of the ESS are optimized and improved. A case study comprising three different cases concludes the paper. The results show that the modified HSA (MHSA can effectively improve the stability and economy of MG operation with an ESS.

    The United Kingdom Pathology Harmony project commenced in 2007 and has been widely mirrored around the world. This initiative evolved through three separate phases of work. Fundamental to the project has been the ability to question variation in the work of the pathology laboratory that has been in place sometimes for a very long time, and yet appears to have little scientific foundation. Work has been undertaken on a methodological approach to studying variation in reference intervals and then moving forward with consensus values. On a wider level there is much else in pathology that can be harmonised from test names and units, through to the clinical guidance we offer for using our tests and work has been undertaken in several of these areas. © 2013.

    Full Text Available Transmission Network Expansion Planning (TNEP is a basic part of power network planning that determines where, when and how many new transmission lines should be added to the network. So, the TNEP is an optimization problem in which the expansion purposes are optimized. Artificial Intelligence (AI tools such as Genetic Algorithm (GA, Simulated Annealing (SA, Tabu Search (TS and Artificial Neural Networks (ANNs are methods used for solving the TNEP problem. Today, by using the hybridization models of AI tools, we can solve the TNEP problem for large-scale systems, which shows the effectiveness of utilizing such models. In this paper, a new approach to the hybridization model of Probabilistic Neural Networks (PNNs and Harmony Search Algorithm (HSA was used to solve the TNEP problem. Finally, by considering the uncertain role of the load based on a scenario technique, this proposed model was tested on the Garver’s 6-bus network.

This algorithm is a combination of a high quality approximation technique called Inverse Distance Weighting and a meta-heuristic algorithm called Harmony Search. The outcome is then polished by a semi-tabu search algorithm. This algorithm adopts a filtering system and determines solution vectors where exact simulation should be applied. The performance of the algorithm is evaluated by standard truss design problems and there has been a significant decrease in the computational effort and improvement of convergence rate.

  1. Adjusting the Parameters of Metal Oxide Gapless Surge Arresters’ Equivalent Circuits Using the Harmony Search Method

    Full Text Available The appropriate circuit modeling of metal oxide gapless surge arresters is critical for insulation coordination studies. Metal oxide arresters present a dynamic behavior for fast front surges; namely, their residual voltage is dependent on the peak value, as well as the duration of the injected impulse current, and should therefore not only be represented by non-linear elements. The aim of the current work is to adjust the parameters of the most frequently used surge arresters’ circuit models by considering the magnitude of the residual voltage, as well as the dissipated energy for given pulses. In this aim, the harmony search method is implemented to adjust parameter values of the arrester equivalent circuit models. This functions by minimizing a defined objective function that compares the simulation outcomes with the manufacturer’s data and the results obtained from previous methodologies.

  2. Inner Peace and Global Harmony: Individual Wellbeing and Global Solutions in the Art of Living

    2014-10-01

    Full Text Available his paper explores the discourse in the Art of Living (AOL, a Hindu derived transnational meditation movement, which suggests that solutions to global problems are best addressed at the individual level. Ethnographic fieldwork, qualita-tive interviews and an analysis of published material suggest that the primary concern of the AOL is the reduction of stress and anxiety for the individual practitioner. This reduction of stress not only means that the individual practitioner develops ‘inner peace', but also contributes to global harmony. AOL is an exemplar of ‘therapeutic solutions', which are characterized by disillusionment with estab-lished institutions and a quest for inner meaning. AOL articulates this therapeutic solution, not only in terms of narcissistic needs, but links this quest for inner meaning to wider social and global concerns.

    In 2003 Nova Scotia Power conducted a dam safety evaluation for the Harmony Hydro System on the Medway River. Flood control at the main dam was performed using crest boards on the overflow section and stoplogs in the sluiceway bays. This process was time consuming, labour intensive and possibly dangerous. A flood analysis had demonstrated that the spillway could not handle the design flood with adequate freeboard, even assuming that all crest boards and stoplogs could be removed. The flood handling capacity of the dam was therefore redesigned, so that infrequent flood events could be passed without any user intervention and larger floods could be passed with the use of quick-release stoplogs. In 2006 and 2007, six bays of quick-release stoplogs, a sluice gate and upgraded overflow spillway were installed. The quick-release stoplogs featured a novel release mechanism consisting of a roller and lever arm, which significantly reduced the effort to release the stoplogs when compared with a typical pull-pin release mechanism. This paper described the novel quick-release mechanism that utilized a lever and roller instead of a pull-pin. The paper discussed the successful design, installation and testing of the quick-release mechanism at the main sluiceway on the Harmony Main Dam in Nova Scotia. The paper described the facility and discussed engineering work that was performed by Hatch Energy between 2003 and 2006. The disadvantages of quick-release stoplogs were also identified. Other topics that were discussed included fabrication and installation as well as commissioning and operation. It was concluded that quick-release stoplog spillways could be cost-effective and efficient elements for flood handling. A difficult design component of traditional quick-release designs has been the pull-pin which releases the central column. Under load conditions, the pull pin can jam and prevent release of the stoplogs. 9 figs.

  4. Are adaptations self-organized, autonomous, and harmonious? Assessing the social-ecological resilience literature

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available The paper analyzes how adaptability (adaptive capacity and adaptations is constructed in the literature on resilience of social-ecological systems (SES. According to some critics, this literature views adaptability as the capacity of SES to self-organize in an autonomous harmonious consensus-building process, ignoring strategies, conflicting goals, and power issues. We assessed 183 papers, coding two dimensions of adaptability: autonomous vs. intentional and descriptive vs. normative. We found a plurality of framings, where 51% of the papers perceived adaptability as autonomous, but one-third constructed adaptability as intentional processes driven by stakeholders; where social learning and networking are often used as strategies for changing power structures and achieving sustainability transformations. For the other dimension, adaptability was used normatively in 59% of the assessed papers, but one-third used descriptive framings. We found no evidence that the SES literature in general assumes a priori that adaptations are harmonious consensus-building processes. It is, rather, conflicts that are assumed, not spelled out, and assertions of "desirable" that are often not clarified by reference to policy documents or explicit normative frameworks. We discuss alternative definitions of adaptability and transformability to clarify or avoid the notion of desirability. Complex adaptive systems framing often precludes analysis of agency, but lately self-organization and emergence have been used to study actors with intentions, strategies, and conflicting interests. Transformations and power structures are increasingly being addressed in the SES literature. We conclude that ontological clashes between social science and SES research have resulted in multiple constructive pathways.

    The Harmony processor was found to be reliable, comfortable and offered a substantially increased battery life compared with the previous generation processor. No significant improvement in speech understanding with HiRes was demonstrated from objective measures, but the majority of subjects showed a clear subjective preference for the combination HiRes 120/Harmony processor. To evaluate experience with the Harmony™ sound processor, together with the HiRes 120 strategy. Postlingually deafened adults implanted with a CII or HiRes 90K were included and divided into three groups: (1) experienced users using the Platinum body-worn processor; (2) experienced users who had been using other processors; (3) new users with the Harmony processor from first fitting. The latter group entered a randomized crossover protocol where half were initially fitted with HiRes and half with HiRes 120. The initial strategy was used for 3 months and the alternative for a further 3 months. Speech perception tests and questionnaires were performed. The study included 65 subjects. Implementing HiRes 120 was straightforward. The speech test group results did not show significant differences between HiRes and HiRes 120. However, the questionnaires showed significantly higher ratings for HiRes 120 in some instances. Subjects were highly satisfied with the Harmony processor.

    Napiórkowska-Krzebietke Agnieszka

    2017-12-01

    Full Text Available Since 1967, the temperate, shallow, pond-type Lake Warniak has been subjected to different biomanipulation methods including the introduction of common carp, Cyprinus carpio L., grass carp, Ctenopharyngodon idella (Val., silver carp, Hypophthalmichthys molitrix (Val., and bighead carp, Hypophthalmichthys nobilis (Richardson and then their removal in an effort to control macrophytes and phytoplankton. Recently, pilot stocking with predatory fish, particularly pike, Esox lucius L., has also been conducted. Hence, an examination of the long-term response patterns of phytoplankton to multiple fish-induced stressors was undertaken. In recent years, Chara domination (2000-2004 has helped to stabilize a clear-water state, high/good ecological status, and meso-eutrophic conditions. After the disappearance of Charales in 2004, the rapid, unstable changes in phytoplankton biomass, structure, and biodiversity suggested a shift toward a turbid-water state. As a result, the phytoplankton assemblages changed from those dominated by cryptophytes Y+X2+X1+LO (2000-2004 through those dominated by cyanobacteria K (2005-2008, dinoflagellates LO+Y (2009-2011, and cryptophytes Y+LO+F+X2 (2012, to those dominated by diatoms D+K+P+A (2013-2014 with representative taxa that occur in nutrient-rich and/or nutrient-poor water bodies. The 1967-2014 changes indicated that four periods, two with clear-water state and two with turbid-water state, alternately, one after the other, resulted from different fish pressure. Higher autochthonous fish biomass was usually accompanied by lower phytoplankton biomass. In contrast, the introduction of Cyprinidae fish had a stimulating effect on summer phytoplankton dominated by cyanobateria. Among the nutrients, only phosphorus played an important role.

  13. A Global-best Harmony Search based Gradient Descent Learning FLANN (GbHS-GDL-FLANN for data classification

    2016-03-01

    Full Text Available While dealing with real world data for classification using ANNs, it is often difficult to determine the optimal ANN classification model with fast convergence. Also, it is laborious to adjust the set of weights of ANNs by using appropriate learning algorithm to obtain better classification accuracy. In this paper, a variant of Harmony Search (HS, called Global-best Harmony Search along with Gradient Descent Learning is used with Functional Link Artificial Neural Network (FLANN for classification task in data mining. The Global-best Harmony Search (GbHS uses the concepts of Particle Swarm Optimization from Swarm Intelligence to improve the qualities of harmonies. The problem solving strategies of Global-best Harmony Search along with searching capabilities of Gradient Descent Search are used to obtain optimal set of weight for FLANN. The proposed method (GbHS-GDL-FLANN is implemented in MATLAB and compared with other alternatives (FLANN, GA based FLANN, PSO based FLANN, HS based FLANN, Improved HS based FLANN, Self Adaptive HS based FLANN, MLP, SVM and FSN. The GbHS-GDL-FLANN is tested on benchmark datasets from UCI Machine Learning repository by using 5-fold cross validation technique. The proposed method is analyzed under null-hypothesis by using Friedman Test, Holm and Hochberg Procedure and Post-Hoc ANOVA Statistical Analysis (Tukey Test & Dunnett Test for statistical analysis and validity of results. Simulation results reveal that the performance of the proposed GbHS-GDL-FLANN is better and statistically significant from other alternatives.

  14. Meaning from environmental sounds: types of signal-referent relations and their effect on recognizing auditory icons.

    Keller, Peter; Stevens, Catherine

    2004-03-01

    This article addresses the learnability of auditory icons, that is, environmental sounds that refer either directly or indirectly to meaningful events. Direct relations use the sound made by the target event whereas indirect relations substitute a surrogate for the target. Across 3 experiments, different indirect relations (ecological, in which target and surrogate coexist in the world; metaphorical, in which target and surrogate have similar appearance or function, and random) were compared with one another and with direct relations on measures including associative strength ratings, amount of exposure required for learning, and response times for recognizing icons. Findings suggest that performance is best with direct relations, worst with random relations, and that ecological and metaphorical relations involve distinct types of association but do not differ in learnability.

    Full Text Available Valine glycine repeat G (VgrG proteins are regarded as one of two effectors of Type VI secretion system (T6SS which is a complex multi-component secretion system. In this study, potential biological roles of T6SS structural and VgrG genes in a rice bacterial pathogen, Acidovorax avenae subsp. avenae (Aaa RS-1, were evaluated under seven stress conditions using principle component analysis of gene expression. The results showed that growth of the pathogen was reduced by H2O2 and paraquat-induced oxidative stress, high salt, low temperature, and vgrG mutation, compared to the control. However, pathogen growth was unaffected by co-culture with a rice rhizobacterium Burkholderia seminalis R456. In addition, expression of 14 T6SS structural and eight vgrG genes was significantly changed under seven conditions. Among different stress conditions, high salt, and low temperature showed a higher effect on the expression of T6SS gene compared with host infection and other environmental conditions. As a first report, this study revealed an association of T6SS gene expression of the pathogen with the host infection, gene mutation, and some common environmental stresses. The results of this research can increase understanding of the biological function of T6SS in this economically-important pathogen of rice.

    Full Text Available The purpose of this study was to explore the combined effect of melatonin receptor type 1A (MTNR1A gene polymorphisms and exposure to environmental carcinogens on the susceptibility and clinicopathological characteristics of oral cancer.Three polymorphisms of the MTNR1A gene from 618 patients with oral cancer and 560 non-cancer controls were analyzed by real-time polymerase chain reaction (PCR. The CTA haplotype of the studied MTNR1A polymorphisms (rs2119882, rs13140012, rs6553010 was related to a higher risk of oral cancer. Moreover, MTNR1A gene polymorphisms exhibited synergistic effects of environmental factors (betel quid and tobacco use on the susceptibility of oral cancer. Finally, oral-cancer patients with betel quid-chewing habit who had T/T allele of MTNR1A rs13140012 were at higher risk for developing an advanced clinical stage and lymph node metastasis.These results support gene-environment interactions of MTNR1A polymorphisms with smoking and betel quid-chewing habits possibly altering oral-cancer susceptibility and metastasis.

    In the present study, a life cycle assessment (LCA) approach was used to analyse the environmental impacts associated with the construction and operational phases of an integrated fixed-film activated sludge (IFAS) reactor treating municipal wastewater. This study was conducted within the boundaries of a research project that aimed to investigate the implementation related challenges of a package type IFAS reactor from an environmental perspective. Along with the LCA results of the construction phase, a comparison of the LCA results of seven operational phases is also presented in this study. The results showed that among all the inputs, the use of stainless steel in the construction phase caused the highest impact on environment, followed by electricity consumption in raw materials production. The impact of the construction phase on toxicity impact indicators was found to be significant compared to all operational phases. Among the seven operational phases of this study, the dissolved oxygen phase III, having a concentration of ∼4.5 mg/L, showed the highest impact on abiotic depletion, acidification, global warming, ozone layer depletion, human toxicity, fresh water eco-toxicity, marine aquatic eco-toxicity, terrestrial eco-toxicity, and photochemical oxidation. However, better effluent quality in this phase reduced the eutrophication load on environment.

  19. Acquired Type III Secretion System Determines Environmental Fitness of Epidemic Vibrio parahaemolyticus in the Interaction with Bacterivorous Protists

    Genome analyses of marine microbial communities have revealed the widespread occurrence of genomic islands (GIs), many of which encode for protein secretion machineries described in the context of bacteria-eukaryote interactions. Yet experimental support for the specific roles of such GIs in aquatic community interactions remains scarce. Here, we test for the contribution of type III secretion systems (T3SS) to the environmental fitness of epidemic Vibrio parahaemolyticus. Comparisons of V. parahaemolyticus wild types and T3SS-defective mutants demonstrate that the T3SS encoded on genome island VPaI-7 (T3SS-2) promotes survival of V. parahaemolyticus in the interaction with diverse protist taxa. Enhanced persistence was found to be due to T3SS-2 mediated cytotoxicity and facultative parasitism of V. parahaemolyticus on coexisting protists. Growth in the presence of bacterivorous protists and the T3SS-2 genotype showed a strong correlation across environmental and clinical isolates of V. parahaemolyticus. Short-term microcosm experiments provide evidence that protistan hosts facilitate the invasion of T3SS-2 positive V. parahaemolyticus into a coastal plankton community, and that water temperature and productivity further promote enhanced survival of T3SS-2 positive V. parahaemolyticus. This study is the first to describe the fitness advantage of GI-encoded functions in a microbial food web, which may provide a mechanistic explanation for the global spread and the seasonal dynamics of V. parahaemolyticus pathotypes, including the pandemic serotype cluster O3:K6, in aquatic environments.

    The Mediterranean region is projected to be extremely vulnerable to global change, which will affect the distribution of typical forest types such as native oak forests. However, our understanding of Mediterranean oak forest responses to future conditions is still very limited by the lack of knowledge on oak forest dynamics and species-specific responses to multiple drivers. We compared the long-term (1966-2006) forest persistence and land cover change among evergreen (cork oak and holm oak) and deciduous oak forests and evaluated the importance of anthropogenic and environmental drivers on observed changes for Portugal. We used National Forest Inventories to quantify the changes in oak forests and explored the drivers of change using multinomial logistic regression analysis and an information theoretical approach. We found distinct trends among oak forest types, reflecting the differences in oak economic value, protection status and management schemes: cork oak forests were the most persistent (62%), changing mostly to pines and eucalypt; holm oak forests were less persistent (53.2%), changing mostly to agriculture; and deciduous oak forests were the least persistent (45.7%), changing mostly to shrublands. Drivers of change had distinct importance across oak forest types, but drivers from anthropogenic origin (wildfires, population density, and land accessibility) were always among the most important. Climatic extremes were also important predictors of oak forest changes, namely extreme temperatures for evergreen oak forests and deficit of precipitation for deciduous oak forests. Our results indicate that under increasing human pressure and forecasted climate change, evergreen oak forests will continue declining and deciduous oak forests will be replaced by forests dominated by more xeric species. In the long run, multiple disturbances may change competitive dominance from oak forests to pyrophytic shrublands. A better understanding of forest dynamics and the

  3. Modelling derecho dynamics and the direct radiative effect of wildfire smoke upon it with NWP model HARMONIE

    Toll, Velle; Männik, Aarne

    2014-05-01

    Convection permitting numerical weather prediction model HARMONIE was used to simulate the dynamics of the derecho that swept over Eastern Europe on August 8, 2010. The storm moved over Belarus, Lithuania, Latvia, Estonia and Finland and the strongest wind gusts (up to 36.5 m/s) were measured in Estonia. The storm path is recorded on the radar images where characteristic bow echo was observed. The model setup was similar to near-future operational, nearly kilometre-scale environments in European national weather services. Hindcast experiments show the ability of the HARMONIE model to predict the severe convective storm and forecast concurrent strong wind gusts. Wind gusts with very similar intensity to observed ones were simulated by the HARMONIE model and 2.5-km horizontal resolution appears sufficient for reliable forecast of the derecho event. The timing of the modelled storm was in good agreement with the observations. The simulated average storm propagation speed was 25 m/s, similar to the radar observations. Hindcast experiments suggest that more precise warning for the storm could have been issued if the HARMONIE model would have been utilised. The derecho event was accompanied by the remarkable smoke aerosol concentrations (maximum total aerosol optical depth more than 4 at 550 nm) originating from the wildfires from Russia. Smoke plume travelled clockwise around Moscow from August 5 to 9. On August 8, 2010, smoke plume was situated on the Eastern border of Estonia. The derecho occurred on the western side of the smoke plume path. HARMONIE experiments were performed to study the direct radiative effect of wildfire smoke on a severe convective storm. The impact of smoke aerosol on the derecho dynamics was investigated. Reduction in the shortwave radiation flux at the surface resulting from aerosol influence simulated by the HARMONIE model is up to 200 W/m2 in the area with the highest aerosol concentrations. This causes near surface cooling of up to 3 º

    The EnviroAerosols on ECMWF HPC project (2015-2017) "Enviro-HIRLAM/ HARMONIE model research and development for online integrated meteorology-chemistry-aerosols feedbacks and interactions in weather and atmospheric composition forecasting" is aimed at analysis of importance of the meteorology-chemistry/aerosols interactions and to provide a way for development of efficient techniques for on-line coupling of numerical weather prediction and atmospheric chemical transport via process-oriented parameterizations and feedback algorithms, which will improve both the numerical weather prediction and atmospheric composition forecasts. Two main application areas of the on-line integrated modelling are considered: (i) improved numerical weather prediction with short-term feedbacks of aerosols and chemistry on formation and development of meteorological variables, and (ii) improved atmospheric composition forecasting with on-line integrated meteorological forecast and two-way feedbacks between aerosols/chemistry and meteorology. During 2015-2016 several research projects were realized. At first, the study on "On-line Meteorology-Chemistry/Aerosols Modelling and Integration for Risk Assessment: Case Studies" focused on assessment of scenarios with accidental and continuous emissions of sulphur dioxide for case studies for Atyrau (Kazakhstan) near the northern part of the Caspian Sea and metallurgical enterprises on the Kola Peninsula (Russia), with GIS integration of modelling results into the RANDOM (Risk Assessment of Nature Detriment due to Oil spill Migration) system. At second, the studies on "The sensitivity of precipitation simulations to the soot aerosol presence" & "The precipitation forecast sensitivity to data assimilation on a very high resolution domain" focused on sensitivity and changes in precipitation life-cycle under black carbon polluted conditions over Scandinavia. At third, studies on "Aerosol effects over China investigated with a high resolution

    Full Text Available A reliable and up-to-date ship emission inventory is essential for atmospheric scientists quantifying the impact of shipping and for policy makers implementing regulations and incentives for emission reduction. The emission modelling in this study takes into account ship type and size dependent input data for 15 ship types and 7 size categories. Global port arrival and departure data for more than 32 000 merchant ships are used to establish operational profiles for the ship segments. The modelled total fuel consumption amounts to 217 Mt in 2004 of which 11 Mt is consumed in in-port operations. This is in agreement with international sales statistics. The modelled fuel consumption is applied to develop global emission inventories for CO2, NO2, SO2, CO, CH4, VOC (Volatile Organic Compounds, N2O, BC (Black Carbon and OC (Organic Carbon. The global emissions from ships at sea and in ports are distributed geographically, applying extended geographical data sets covering about 2 million global ship observations and global port data for 32 000 ships. In addition to inventories for the world fleet, inventories are produced separately for the three dominating ship types, using ship type specific emission modelling and traffic distributions.

    A global Chemical Transport Model (CTM was used to calculate the environmental impacts of the emissions. We find that ship emissions is a dominant contributor over much of the world oceans to surface concentrations of NO2 and SO2. The contribution is also large over some coastal zones. For surface ozone the contribution is high over the oceans but clearly also of importance over Western North America (contribution 15–25% and Western Europe (5–15%. The contribution to tropospheric column ozone is up to 5–6%. The overall impact of ship emissions on global methane lifetime is large due to the high NOx emissions. With

  8. Optimum Design of Braced Steel Space Frames including Soil-Structure Interaction via Teaching-Learning-Based Optimization and Harmony Search Algorithms

    Full Text Available Optimum design of braced steel space frames including soil-structure interaction is studied by using harmony search (HS and teaching-learning-based optimization (TLBO algorithms. A three-parameter elastic foundation model is used to incorporate the soil-structure interaction effect. A 10-storey braced steel space frame example taken from literature is investigated according to four different bracing types for the cases with/without soil-structure interaction. X, V, Z, and eccentric V-shaped bracing types are considered in the study. Optimum solutions of examples are carried out by a computer program coded in MATLAB interacting with SAP2000-OAPI for two-way data exchange. The stress constraints according to AISC-ASD (American Institute of Steel Construction-Allowable Stress Design, maximum lateral displacement constraints, interstorey drift constraints, and beam-to-column connection constraints are taken into consideration in the optimum design process. The parameters of the foundation model are calculated depending on soil surface displacements by using an iterative approach. The results obtained in the study show that bracing types and soil-structure interaction play very important roles in the optimum design of steel space frames. Finally, the techniques used in the optimum design seem to be quite suitable for practical applications.

    Type 1 diabetes is a chronic, incurable childhood disease. Chronically uncontrolled diabetes is associated with eye, kidney, nerve, heart and blood vessel damage and function impairment. The aim of this study was to evaluate the impact of various social and environmental factors, with a particular emphasis on education, on the level of metabolic control in diabetes. The survey research was conducted in 102 children aged 0-18 years, diagnosed with type 1 diabetes. Based on the HbA(1c ) level, patients were divided into: group A (63 patients with fairly well and moderately controlled type 1 diabetes mellitus) and group B (39 patients with metabolically uncontrolled type 1 diabetes mellitus). The impact of various environmental and social factors on the degree of metabolic control of type 1 diabetes was analysed. No effect of typical environmental and social factors, such as: place of residence, gender, parents' education and their professional activity, on the level of metabolic control of type 1 diabetes was found. However, groups A and B significantly differed in the level of knowledge about diabetes and its treatment, in the regularity of meals, in possessing a nutrition scale and in the self-assessed preparation for taking care and custody of a child with type 1 diabetes. 1. Children with type 1 diabetes and their parents require ongoing education about the disease and its treatment. 2. The regularity of meals and the use of a nutrition scale have considerable impact on the level of metabolic control of the disease.

    Full Text Available The impact of the dialogue between cultures can meet national and "internal" dimensions and features or even regional and "external” ones. In order to grasp all the dimensions of this paradigm shift, it is important to try understanding the concepts of and interactions between culture, conflict and dialogue as an array, where conflict has to be always isolated between the other two concepts.The main aim of the paper is to underline the idea that just having a fair dialogue between cultures and religions followers can be established a sustainable harmony among them. Culture is closely connected to a community environment. Indeed, culture is essentially collective and it affects and influences human behavior. Culture helps people to build and preserve their own identity. Identity stems from the consciousness of difference. Sometimes, this identity sharpens after a confrontation. It strengthens the self‐esteem of the individual, and it makes it easier for the individual to accept compromises in deals with other parties without being afraid of “losing face” or “losing values” or “misunderstanding values”.

    2016-11-01

    Full Text Available The management of construction companies’ development is rarely aimed at harmonization of business and at the development of the ways of its sustainable development. Case studies and the application scope for harmonization as an approach allowing systematic and balanced development of business showed its practical relevance. The use of this approach allows not only correlating the objectives, clarifying the mission, structuring the problems, or determining the optimal salary of employees, but also correlating the costs to each other, which is particularly important in light of the need for rapid transformation of the building production methods. They are based on competent use of system properties of the systems. The properties of emergence, resonance, measurability, and others are of particular importance. Their accounting allows achieving the optimal cost outlay required in the process of investment and construction activities. It complies with the requirements and conditions of the market economy. The mentioned advantages of the use of harmonization technologies to ensure the stability and sustainability of investment and construction activities enable to confirm the hypothesis of the impossibility to achieve the optimum cost, for example, for the implementation of an investment and construction project without implementation of the system properties of a harmonious approach.

    The power of poetry is universally acknowledged, but it is debatable whether its appreciation is reserved for experts. Here, we show that readers with no particular knowledge of a traditional form of Welsh poetry unconsciously distinguish phrases conforming to its complex poetic construction rules from those that violate them. We studied the brain response of native speakers of Welsh as they read meaningful sentences ending in a word that either complied with strict poetic construction rules, violated rules of consonantal repetition, violated stress pattern, or violated both these constraints. Upon reading the last word of each sentence, participants indicated sentence acceptability. As expected, our inexperienced participants did not explicitly distinguish between sentences that conformed to the poetic rules from those that violated them. However, in the case of orthodox sentences, the critical word elicited a distinctive brain response characteristic of target detection -the P3b- as compared to the other conditions, showing that speakers of Welsh with no expertise of this particular form of poetry implicitly detect poetic harmony. These results show for the first time that before we even consider literal meaning, the musical properties of poetry speak to the human mind in ways that escape consciousness.

    Full Text Available We consider a class of stochastic search algorithms of global optimization which in various publications are called behavioural, intellectual, metaheuristic, inspired by the nature, swarm, multi-agent, population, etc. We use the last term.Experience in using the population algorithms to solve challenges of global optimization shows that application of one such algorithm may not always effective. Therefore now great attention is paid to hybridization of population algorithms of global optimization. Hybrid algorithms unite various algorithms or identical algorithms, but with various values of free parameters. Thus efficiency of one algorithm can compensate weakness of another.The purposes of the work are development of hybrid algorithm of global optimization based on known algorithms of harmony search (HS and swarm of particles (PSO, software implementation of algorithm, study of its efficiency using a number of known benchmark problems, and a problem of dimensional optimization of truss structure.We set a problem of global optimization, consider basic algorithms of HS and PSO, give a flow chart of the offered hybrid algorithm called PSO HS , present results of computing experiments with developed algorithm and software, formulate main results of work and prospects of its development.

  16. "Lesbians are not women": feminine and lesbian sensibilities in Harmony Hammond's late-1970s sculpture.

    Thompson, Margo Hobbs

    2008-01-01

    Harmony Hammond's wrapped fabric sculptures are placed in context of the theories of gender and sexuality that circulated among lesbian and straight feminists at the time they were made, the late 1970s. Hammond has cited in particular Monique Wittig's novels, such as The Lesbian Body, and her essays including "The Straight Mind" where Wittig concludes that the lesbian is not a woman. The critique to which Wittig's lesbian separatism has been subjected by Judith Butler in her consideration of the appeal and limitations of essentialism also applies to Hammond's art. Hammond's use of vaginal imagery was instrumental to visualizing a lesbian sensibility, but the proposition of such a sensibility established a new problematic: a new essential category. The article concludes that because Hammond's work was produced in the context of a complex set of discourses, lesbian, feminist, and aesthetic, it resisted reduction to a singular meaning. Her sculptures avoided the pitfall of substituting one essence for another, lesbian for feminine sensibility, but activated both. The sculptures effectively queered vaginal imagery: When Hammond used vaginal imagery to represent lesbian sensibility, she subverted the equation of sex and gender and the essentialist notion of feminine sensibility.

The listen-before-talk (LBT mechanism is mainly considered to enable an LTE operator to protect other incumbent unlicensed systems. In this article, we investigate the behaviors of multiple LTE operators along with the deployment of WiFi networks in the unlicensed spectrum from both short- and long-term points of view. In countries without mandatory LBT requirements, we show that an LTE operator is susceptible to collusion with another LTE operator, thus exploiting scarce spectrum resources by deceiving other wireless networks into thinking that channels are always busy; hence, mandatory usage of LTE with LBT is highly recommended at national level to achieve harmonious coexistence in the unlicensed spectrum. We discuss several possible coexistence scenarios to resolve the operator’s dilemmaas well as to improve unlicensed spectrum efficiency among multi-RAT systems, which is viable in the near future.

    The contents of engineering design should indeed contain both science and art fields. However, the art aspect is too less discussed to cause an inharmonic impact with natural surroundings, and so are check dams. This study would like to seek more opportunities of check dams' harmony with nearby circumstances. According to literatures review of philosophy and cognition science fields, we suggest a thinking process of three phases to do check dams design work for reference. The first phase, conceptualization, is to list critical problems, such as the characteristics of erosion or deposition, and translate them into some goal situations. The second phase, transformation, is to use cognition methods such as analogy, association and metaphors to shape an image and prototypes. The third phase, formation, is to decide the details of the construction, such as stable safety analysis of shapes or materials. According to the previous descriptions, Taiwan's technological codes or papers about check dam design mostly emphasize the first and third phases, still quite a few lacks of the second phase. We emphases designers shouldn't ignore any phase of the framework especially the second one, or they may miss some chances to find more suitable solutions. Otherwise, this conceptual framework is simple to apply and we suppose it's a useful tool to design a more harmonic check dam with nearby natural landscape. Key Words: check dams, design thinking process, conceptualization, transformation, formation.

  20. The Postcolonial Self and the Other in Béla Tarr’s Werckmeister Harmonies

    Full Text Available This work sets off to offer a polemical response to postcolonialist theories advanced by Homi Bhabha in his seminal work The Location of Culture, particularly to Bhabha’s famous notions of ambivalence and mimicry purportedly used as methods of struggle against colonialism. Reading Béla Tarr’s film Werckmeister Harmonies (Werckmeister harmóniák, 2000 as an allegory for the colonization of a former colonial agent in the guise of an ambiguously framed post-imperial Hungary now on the eve of Soviet invasion, I turn Bhabha’s notions on their heads, and thus de-stereotype the simplistic hierarchy that sees the colonial agent dominate the colonized subject in a top-down approach. To achieve this, I bring into play Kuan-Hsing Chen’s notion of deimperialization as well as the psychoanalysis of Octave Mannoni in order to show that rather than being a straightforward misreading of the Other by an uninformed Self, the relationship between colonized and colonizer appears more like a failed attempt at acquiring the most basic knowledge of the psychological functioning of the Self on both sides of the colonized/colonizer divide.

    Enteric pathogens employ sophisticated strategies to colonize and infect mammalian hosts. Gram-negative bacteria, such as Escherichia coli , Salmonella , and Campylobacter jejuni , are among the leading causes of gastrointestinal tract infections worldwide. The virulence strategies of many of these Gram-negative pathogens rely on type III secretion systems (T3SSs), which are macromolecular syringes that translocate bacterial effector proteins directly into the host cytosol. However, synthesis of T3SS proteins comes at a cost to the bacterium in terms of growth rate and fitness, both in the environment and within the host. Therefore, expression of the T3SS must be tightly regulated to occur at the appropriate time and place during infection. Enteric pathogens have thus evolved regulatory mechanisms to control expression of their T3SSs in response to specific environmental and host cues. These regulatory cascades integrate multiple physical and chemical signals through complex transcriptional networks. Although the power of bacterial genetics has allowed elucidation of many of these networks, the biochemical interactions between signal and sensor that initiate the signaling cascade are often poorly understood. Here, we review the physical and chemical signals that Gram-negative enteric pathogens use to regulate T3SS expression during infection. We highlight the recent structural and functional studies that have elucidated the biochemical properties governing both the interaction between sensor and signal and the mechanisms of signal transduction from sensor to downstream transcriptional networks.

    Large-scale integration of wind turbine generators (WTGs) may have significant impacts on power system operation with respect to system frequency and bus voltages. This paper studies the effect of Static Var Compensator (SVC) connected to wind energy conversion system (WECS) on voltage profile and the power generated from the induction generator (IG) in wind farm. Also paper presents, a dynamic reactive power compensation using Static Var Compensator (SVC) at the a point of interconnection of wind farm while static compensation (Fixed Capacitor Bank) is unable to prevent voltage collapse. Moreover, this paper shows that using advanced optimization techniques based on artificial intelligence (AI) such as Harmony Search Algorithm (HS) and Self-Adaptive Global Harmony Search Algorithm (SGHS) instead of a Conventional Control Method to tune the parameters of PI controller for SVC and pitch angle. Also paper illustrates that the performance of the system with controllers based on AI is improved under different operating conditions. MATLAB/Simulink based simulation is utilized to demonstrate the application of SVC in wind farm integration. It is also carried out to investigate the enhancement in performance of the WECS achieved with a PI Controller tuned by Harmony Search Algorithm as compared to a Conventional Control Method.

    Stelian Brad

    2016-05-01

    Full Text Available Economic growth and sustainable development are important issues for social prosperity. Sustainable development strives for moderate and responsible use within the economic activity of the limited resources of our planet, whereas economic growth does not limit the resource exploitation and energy, being mainly focused on productivity increase. From this perspective, both conceptual and operational contradictions occur between the two pillars of prosperity. This paper looks to these contradictions and proposes some streams of intervention such as economic growth and environmental sustainability to operate in harmony. A structured framework for innovative problem solving is considered in this respect. Results of this research show that it is possible to induce smart measures in the economic system for directing businesses towards new paradigms where economic growth is possible without negative effects on environmental sustainability.

    Full Text Available La formation des gentilés, particulièrement sensible aux contraintes d’euphonie, permet de mettre en évidence, pour le français, deux manifestations complémentaires de la contrainte dissimilative. L’une, négative, tend à éviter la consécution à faible distance du même phonème ou de deux phonèmes proches. Elle explique la sous-représentation des deux principaux suffixes, -ais et -ois, après une accroche en sifflante, à cause de la sifflante conte-nue par le suffixe au féminin, ainsi que la sous-représentation de -ais après /E/ et de -ois après /A/. L’autre, positive, favorise entre les voyelles une harmonie fondée sur les contrastes. De-vant les suffixes dont la voyelle est une voyelle d’avant moyenne ou haute (-ais, -ain, -in, -ier…, sont privilégiés les radicaux dont la dernière voyelle est une voyelle d’arrière moyenne ou basse, et de préférence un /O/ plutôt qu’un /A/. Devant les suffixes dont la voyelle est une voyelles d’arrière moyenne ou basse (-ois, -ot, -on, -and, -at, -ard…, sont privilégiés les radi-caux dont la dernière voyelle est une voyelle d’avant moyenne ou haute, et de préférence un /i/ plutôt qu’un /E/. Pour cela, un yod au contact du suffixe joue le même rôle qu’un /i/ dans la syllabe précédente. Cette harmonie est obtenue soit par la sélection du suffixe, soit par un aménagement – substitution, épenthèse, troncation, insertion d’un interfixe, etc. – du radical fourni par la base. On observe d’autre part une harmonisation de l’accroche consonantique du radical avec la voyelle du suffixe. Devant -ois, sont privilégiées les attaques en labiale ou en vélaire, en accord avec le double caractère du /w/ propre à ce suffixe. Devant -ais et -ain, ce sont les attaques en dentale. Devant -ot, -on, -and, -at, -ard, la tendance à rapprocher l’articu-lation de la consonne de celle de la voyelle peut aller jusqu’aux vélaires mais elle s’arrête sou

    2017-12-19

    An environmental radiation detector for detecting and distinguishing between all types of environmental radiation, including photons, charged particles, and neutrons. A large volume high pressure ionization chamber (HPIC) includes BF.sub.3 gas at a specific concentration to render the radiation detector sensitive to the reactions of neutron capture in Boron-10 isotope. A pulse-mode readout is connected to the ionization chamber capable of measuring both the height and the width of the pulse. The heavy charged products of the neutron capture reaction deposit significant characteristic energy of the reaction in the immediate vicinity of the reaction in the gas, producing a signal with a pulse height proportional to the reaction energy, and a narrow pulse width corresponding to the essentially pointlike energy deposition in the gas. Readout of the pulse height and the pulse width parameters of the signals enables distinguishing between the different types of environmental radiation, such as gamma (x-rays), cosmic muons, and neutrons.

  10. Dissonance and harmony between global and regional-scale seismic anisotropy and mantle dynamics

    2017-12-01

    Huge numbers of SKS splitting observations and improved surface-wave based models of azimuthal anisotropy have advanced our understanding of how convection is recorded in mantle fabrics in the upper mantle. However, we are still debating the relative importance of frozen to actively forming olivine fabrics, subduction zone anisotropy lacks a clear reference model, and regional marine studies yield conflicting evidence as to what exactly is going on at the base of the plates and below. Here, I review the degree of agreement between regional and global observations of seismic anisotropy and how well those may be matched by first-order mantle convection models. Updated bean counting can help contextualize the spatial scales of alignment, and I discuss several examples of the relative roles of plate shear to mantle density anomalies and frozen-in structure for oceanic and continental plates. Resolution of seismological models is globally uneven, but there are some locales where such exercises may yield information on the relative strength of asthenosphere and mantle. Another long-standing question is how olivine fabrics record flow under different stress and volatile conditions. I illustrate how different petrological assumptions might be used to reconcile observations of azimuthal dependency of wave speeds for both Love and Rayleigh waves, and how this could improve our models of the upper mantle, much in the spirit of Montagner's vectorial tomography. This is but one approach to improve the regional realism of global geodynamic background models to understand where in space and time dissonance arises, and if a harmonious model may yet be constructed given our assumptions about the workings of the mantle.

    Ferric oxide minerals in atmospheric dust can influence atmospheric temperatures, accelerate melting of snow and ice, stimulate marine phytoplankton productivity, and impact human health. Such effects vary depending on iron mineral type, size, surface area, and solubility. Generally, the presence of ferric oxides in dust is seen in the red, orange, or yellow hues of plumes that originate in North Africa, central and southwest Asia, South America, western North America, and Australia. Despite their global importance, these minerals in source sediments, atmospheric dust, and downwind aeolian deposits remain poorly described with respect to specific mineralogy, particle size and surface area, or presence in far-traveled aerosol compounds. The types and properties of iron minerals in atmospheric dust can be better understood using techniques of rock magnetism (measurements at 5-300 K), Mössbauer and high-resolution visible and near-infrared reflectance spectroscopy; chemical reactivity of iron oxide phases; and electron microscopy for observing directly the ferric oxide coatings and particles. These studies can elucidate the diverse environmental effects of iron oxides in dust and can help to identify dust-source areas. Dust-source sediments from the North American Great Basin and Colorado Plateau deserts and the Kalahari Desert, southern Africa, were used to compare average reflectance values with a magnetic parameter (hard isothermal remanent magnetization, HIRM) for ferric oxide abundance. Lower reflectance values correspond strongly with higher HIRM values, indicating that ferric oxides (hematite or goethite, or both) contribute to absorption of solar radiation in these sediments. Dust deposited to snow cover of the San Juan Mountains (Colorado) and Wasatch Mountains (Utah) was used to characterize dust composition compared with properties of sediments exposed in source-areas identified from satellite retrievals. Results from multiple methods indicate that

    Terrestrial carbon cycling is a function of the growth and survival of trees. Current model representations of tree growth and survival at a global scale rely on coarse plant functional traits that are parameterized very generally. In view of the large biodiversity in the tropical forests, it is important that we account for the functional diversity in order to better predict tropical forest responses to future climate changes. Several next generation Earth System Models are moving towards a size-structured, trait-based approach to modelling vegetation globally, but the challenge of which and how many traits are necessary to capture forest complexity remains. Additionally, the challenge of collecting sufficient trait data to describe the vast species richness of tropical forests is enormous. We propose a more fundamental approach to these problems by characterizing forests by their patterns of survival. We expect our approach to distill real-world tree survival into a reasonable number of functional types. Using 10 large-area tropical forest plots that span geographic, edaphic and climatic gradients, we model tree survival as a function of tree size for hundreds of species. We found surprisingly few categories of size-survival functions emerge. This indicates some fundamental strategies at play across diverse forests to constrain the range of possible size-survival functions. Initial cluster analysis indicates that four to eight functional forms are necessary to describe variation in size-survival relations. Temporal variation in size-survival functions can be related to local environmental variation, allowing us to parameterize how demographically similar groups of species respond to perturbations in the ecosystem. We believe this methodology will yield a synthetic approach to classifying forest systems that will greatly reduce uncertainty and complexity in global vegetation models.

    Whole-genome sequencing (WGS) of 41 patient and environmental sequence type 22 methicillin-resistant Staphylococcus aureus staphylococcal cassette chromosome mec type IV (ST22-MRSA-IV) isolates recovered over 6 weeks in one acute hospital ward in Dublin, Ireland, where ST22-MRSA IV is endemic, revealed 228 pairwise combinations differing by transmission events (CTEs). In contrast, 15 pairwise combinations of isolates representing five CTEs were previously identified by conventional molecular epidemiological typing. WGS enhanced ST22-MRSA-IV tracking and highlighted potential transmission of MRSA via the hospital environment. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

    To understand the genotypic spectrum of environmental contamination of Staphylococcus aureus in households and its persistence. Prospective longitudinal cohort investigation. Index participants identified at 2 academic medical centers. Adults and children with S. aureus skin infections and their household contacts in Los Angeles and Chicago. Household fomites were surveyed for contamination at baseline and 3 months. All isolates underwent genetic typing. We enrolled 346 households, 88% of which completed the 3-month follow-up visit. S. aureus environmental contamination was 49% at baseline and 51% at 3 months. Among households with a USA300 methicillin-resistant S. aureus (MRSA) body infection isolate, environmental contamination with an indistinguishable MRSA strain was 58% at baseline and 63% at 3 months. Baseline factors associated with environmental contamination by the index subject's infection isolate were body colonization by any household member with the index subject's infection isolate at baseline (odds ratio [OR], 10.93 [95% confidence interval (CI), 5.75-20.79]), higher housing density (OR, 1.47 [95% CI, 1.10-1.96]), and more frequent household fomite cleaning (OR, 1.62 [95% CI, 1.16-2.27]). Household environmental contamination with the index subject's infection strain at 3 months was associated with USA300 MRSA and a synergistic interaction between baseline environmental contamination and body colonization by any household member with the index subject's infection strain. We found that infecting S. aureus isolates frequently persisted environmentally in households 3 months after skin infection. Presence of pathogenic S. aureus strain type in the environment in a household may represent a persistent reservoir that places household members at risk of future infection.

    Full Text Available One of important aspects in educating children to have a harmonious, balanced, and lasting family is to concern on parenting since early times. One of the ways is to hug a child. This paper discusses the importance of child development so they can build a harmonious family. When the parent demonstrates their affections to their children by hugging, the children will get a double touch from their parent (father and mother and they do not get the touch from one of them. Hugging children has a big role to child development in the future. The more the parent gives a sincere affection, positive situation, friendship, the more children will get strong of personality. A good and health personality will affect self-children positively when they build a family to become a harmony family. On the contrary, the less the parent give a warm hugging likes no affections and sincerity, derision, insult and reproach; the more the children will get a sick personality. Such personality will be a problem for children either in the present times or during the development period from childhood to teenage and adult. أحد الجوانب الهامة المؤدية إلى أن تكون أسرة الولد في المستقبل أسرة سعيدة مستقرّة وفي دوامهما هو نمط الحضانة الصحيحة منذ البداية.  ومن كيفيات الحضانة والتربية هي تحضين الولد ومعانقته. حاولت هذه المقالة نقاش أهمية " معانقة الأبناء"  لنشوئهم وتطوّرهم حتى كوّنوا في المستقبل أسرة سعيدة مستقرّة. بهذه العملية - معانقة الأبناء- سيحصل الأبناء على اللمستين ( المعانقة الحارة من الوالدين لا من طرف واحد فقط( الأم. ومعانقة الأبناء لها دور كبير في نموّ الأبناء وتطوّرهم في المستقبل. إذا ت

    Dwarf elliptical galaxies (dEs) are the most common galaxy class in dense environments. They are also a surprisingly inhomogenous class, which has made it challenging both to relate different dE subtypes to each other, as well as place the whole class in the larger context of galaxy assembly and (trans)formation processes. Here we will show the effects of environmental evolution on Virgo Cluster and field dEs, presenting the first large-scale integral-field spectroscopic (SAURON) data for this galaxy class. Our sample consists of 12 galaxies and no two of them are alike. We find that the level of rotation is not tied to flattening; we observe kinematic twists; we discover large-scale kinematically-decoupled components; we see varying gradients in line-strength maps. This great variety of morphological, kinematic, and stellar population parameters supports the claim that dEs are defunct dwarf spiral/irregular galaxies and points to a formation scenario that allows for a stochastic shaping of galaxy properties. The combined influence of ram-pressure stripping and harassment fulfils this requirement, still, their exact impact is not yet understood. We thus further investigate the properties of our sample by performing a detailed comprehensive analysis of its kinematic, dynamical, and stellar population properties. We infer the total (dark and baryonic) matter distribution by fitting the observed stellar velocity and velocity dispersion with the solutions of the Jeans equations. We obtain 2D age, metallicity, and enrichment information from line-strength analysis. We then tie these results to the galaxies' intrinsic (i.e. deprojected) locations in the cluster with the use of surface-brightness fluctuation distances. This step is essential to providing unbiased correlations with the local environment density. We show that the dark matter fraction, unlike the level of rotational support, appears to correlate with the clustrocentric distance, and that our dwarfs have

    A radiation protection policy that is truly in harmony with human life and the ecosystem cannot insist that radiation doses be reduced to as low as achievable regardless of the impact of such a policy on other aspects of human life and the ecosystem. This potential conflict of purposes can be approached from several directions, some of which are explored here. First, we must consider the presence of a large and variable background of natural radiation, whose health and ecological effects are virtually identical to those from human-generated radiation. To attempt to measure, account for, and reduce additional radiation sources that are far smaller than this background-indeed, far smaller than the natural variations in the background, affronts both science and common sense. Second, to base policy on extrapolation of several orders of magnitude from health effects resulting from high-level, high-dose rate, radiation is another serious departure from proper scientific practice. Third, to justify current policy as being conservative in the face of uncertainty is wrong on both counts. The uncertainty claimed by the policy makers is based on their unwillingness to consider and apply the enormous body of available evidence. The presumption of conservatism is based on the issue in question: that any level of radiation is deemed potentially harmful. Fourth, by not fully considering the cost of implementing current radiation policy, limited societal resources are diverted from critical needs, for little or no societal benefit. There are good data showing that health of the people and the environment are directly impacted by the amount of money available in the society to benefit real needs. In addition, the fear generated by the presumption that all radiation is harmful, leads to avoidance of life-saving medical techniques such as mammograms, irradiation of food, applications of radiation such as smoke detectors and medical research, reduction of air and ground pollution

  5. Transcriptional profiling of type II toxin-antitoxin genes of Helicobacter pylori under different environmental conditions: identification of HP0967-HP0968 system

    2016-11-01

    Full Text Available Helicobacter pylori is a Gram-negative bacterium that colonizes the human gastric mucosa and is responsible for causing peptic ulcers and gastric carcinoma. The expression of virulence factors allows the persistence of H. pylori in the stomach, which results in a chronic, sometimes uncontrolled inflammatory response. Type II toxin-antitoxin systems have emerged as important virulence factors in many pathogenic bacteria. Three type II toxin-antitoxin (TA systems have previously been identified in the genome of H. pylori 26695: HP0315-HP0316, HP0892-HP0893, and HP0894-HP0895. Here we characterized a heretofore undescribed type II TA system in H. pylori, HP0967-HP0968, which is encoded by the bicistronic operon hp0968-hp0967 and belongs to the Vap family. The predicted HP0967 protein is a toxin with ribonuclease activity whereas HP0968 is an antitoxin that binds to its own regulatory region. We found that all type II TA systems were expressed in H. pylori during early stationary growth phase, and differentially expressed in the presence of urea, nickel, and iron, although the hp0968-hp0967 pair was the most affected under these environmental conditions. Transcription of hp0968-hp0967 was strongly induced in a mature H. pylori biofilm and when the bacteria interacted with AGS epithelial cells. Kanamycin and chloramphenicol considerably boosted transcription levels of all the four type II TA systems. The hp0968-hp0967 TA system was the most frequent among 317 H. pylori strains isolated from all over the world. This study is the first report on the transcription of type II TA genes in H. pylori under different environmental conditions. Our data show that the HP0967 and HP0968 proteins constitute a bona fide type II TA system in H. pylori, whose expression is regulated by environmental cues, which are relevant in the context of infection of the human gastric mucosa.

    To explore the coping strategies of Chinese family caregivers of stroke-impaired older relatives. Many stroke-impaired patients rely heavily on support from their families, and the daily lives of such family caregivers are severely impacted. However, services and support for family caregivers of stroke-impaired relatives in the home setting have received little attention. Appropriate and relevant information and support to family caregivers are important in facilitating the care-giving task. It is, therefore, necessary to understand the nature and demands of care-giving before planning specific educational and support programmes. Grounded theory. Fifteen Chinese family caregivers of stroke-impaired older relatives were recruited and interviewed in 2003 and 2004. Theoretical sampling and constant comparative analysis were used to recruit the sample and perform data analysis. Seeking harmony to provide care for the stroke-impaired was the core category for describing and guiding the family care-giving process, with five main stages: (1) living with ambiguity, (2) monitoring the recovery progress, (3) accepting the downfalls, (4) meeting family obligations and (5) reconciling with harmony. These issues were seldom discussed openly with health professionals. The findings indicated that Chinese family caregivers determine their own needs by seeking harmony to continue to provide care without thinking about getting help from others or their own health problems. These findings help to define some of the complex dynamics that have an impact on the development of partnership care and might challenge nurses practising in the community. Community nurses should assess and understand the coping strategies of family caregivers and assist them to engage in stress-reducing practices. This is an important partnership to be formed in stroke care for family caregivers in the community. The study findings will guide further development of family care-giving aspects in nursing practice

    A principal factor in maintaining positive family functioning and well-being, family communication time is decreasing in modern societies such as Hong Kong, where long working hours and indulgent use of information technology are typical. The objective of this paper is to describe an innovative study protocol, "Happy Family Kitchen," under the project, "FAMILY: A Jockey Club Initiative for a Harmonious Society," aimed at improving family health, happiness, and harmony (3Hs) through enhancement of family communication. This study employed the community-based participatory research (CBPR) approach, and adopted 5 principles of positive psychology and the traditional Chinese concepts of cooking and dining, as a means to connect family members to promote family health, happiness, and harmony (3Hs). In-depth collaboration took place between an academic institution and a large nongovernmental community organization association (NGO association) with 400 social service agency members. Both groups were deeply involved in the project design, implementation, and evaluation of 23 community-based interventions. From 612 families with 1419 individuals' findings, significant increases in mean communication time per week (from 153.44 to 170.31 minutes, P=.002) at 6 weeks after the intervention and mean communication scores (from 67.18 to 69.56 out of 100, P<.001) at 12 weeks after the intervention were shown. Significant enhancements were also found for mean happiness scores 12 weeks after the intervention (from 7.80 to 7.82 out of 10, P<.001), and mean health scores (from 7.70 to 7.73 out of 10, P<.001) and mean harmony scores (from 7.70 to 8.07 out of 10, P<.001) 6 weeks after the intervention. This was the first CBPR study in a Hong Kong Chinese community. The results should be useful in informing collaborative intervention programs and engaging public health researchers and community social service providers, major stakeholders, and community participants in the promotion of

    Environmental horticulture firms provide a variety of commercial/residential landscape products and services encompassing ornamental plant production, design, installation, and maintenance. The companies generate tons of waste including plastic containers, trays, and greenhouse/field covers, creating the need to reduce and utilize plastic waste. Based on survey data collected in Georgia in 2013, this paper investigates determinants of the environmental horticulture firms' recycling decision (plastic containers, flats, and greenhouse poly). Our findings indicate that the decision to discard vs. recycle plastic containers, flats, and greenhouse poly is significantly influenced by firm scope, size, location, and partnership with recycling providers, as well as whether recycling providers offer additional waste pickup services. Insights from this study are of use to local governments and environmental organizations interested in increasing horticultural firm participation in recycling programs and lowering the volume of plastic destined for landfills.

    The electroantennogram method was used to investigate the number of distinct olfactory receptor neuron types responding to a range of behaviorally active volatile chemicals in gravid Queensland fruit flies, Bactrocera tryoni. Three receptor neuron types were identified. One type responds to methyl butyrate, 2-butanone, farnesene, and carbon dioxide; a second to ethanol; and a third to n-butyric acid and ammonia. The receptor neuron type responding to methyl butyrate, 2-butanone, farnesene, and carbon dioxide consists of three subtypes. The presence of a limited number of receptor neuron types responding to a diverse set of chemicals and the reception of carbon dioxide by a receptor neuron type that responds to other odorants are novel aspects of the peripheral olfactory discrimination process.

    Nature and culture are elements that play an important role in the development of a place. Sites of Walisanga spread all over Java since in 16 century. Muslim communities respect respect for these sites. These sites have become an attractive destination of religious tourism on the North Coast of Java. Some of these sites are very close to nature and as a part culture. Shinto shrines and Buddhist temples in Japan are the examples of the master pieces of indigenous architecture which are still maintained very well. The Japanese religious sites with the beautiful architecture and landscape in the culture format have been successfully attracting tourist from all over the world. This paper aims to determine the potency and problems associated with the development of spatial harmony between the nature and culture on the Walisanga religious sites in Indonesia by conducting a dialogue with best practices cases in Japan. This study used descriptive analysis methods. The result showed that, there are similarities between Indonesian and Japan in treating cultural heritage assets. Indonesian government gives quite significant roles to public to participate in preserving cultural heritage. Japan government has given support through the modern technology and funding, assets registration, maintenance and protection, and the assets management. Creating the harmony between nature and culture is necessary to enhance performance, facilities and infrastructure.

    In this paper, we used land use/cover ecosystem service value estimation model and ecological economic coordination degree model to analyze the changes of the ecosystem service value by the land use/cover changes during 1985, 1990, 1996, 2000, 2005 and 2011 in Yanqi Basin, Xin-jiang. Then we evaluated the ecology-economy harmony and the regional differences. The results showed that during 1985-2011, there was an increasing trend in the areas of waters, wetland, sand, cultivated land and construction land in Yanqi Basin. In contrast, that of the saline-alkali land, grassland and woodland areas exhibited a decreasing trend. The ecosystem service value in Yanqi Basin during this period presented an increasing trend, among which the waters and cultivated land contributed most to the total value of ecosystem services, while the grassland and the woodland had obviously declined contribution to the total value of ecosystem services. The research showed that the development of ecological economy in the study area was at a low conflict and low coordination level. So, taking reasonable and effective use of the regional waters and soil resources is the key element to maintain the ecosystem service function and sustainable and harmonious development of economy in Yanqi Basin.

    Directory of Open Access Journals (Sweden)

    Jajtner Tomáš

    2015-07-01

    Full Text Available The following paper deals with the interpretation of one of the major “Cromwellian” poems of Andrew Marvell (1621-1678, “The First Anniversary of the Government under His Highness the Lord Protector”, 1655. The poem is first set in the context of Marvell’s poetry and his public career in the period between 1637 and 1660. The article then identifies and analyses three main themes of “The First Anniversary”: the notion of a new aeon starting with Cromwell’s rule and the apocalyptical imagery related to his Protectorate, the concept of his power and authority between liberty and tyranny, and the relation between the harmony established by Cromwell and classical Pythagorean harmonious lore. The author argues that the imagery Marvell uses to describe the nature of the regime (especially the concept of Cromwell’s “no-kingship” shows a deeply paradoxical structure, which uncovers the frailty and insecurity of Cromwell’s dictatorship as well as the circular logic of its justification. In that sense, the poem can be read as a vivid manifestation of the dilemmas and tensions of this period.

    On August 8, 2010, a derecho swept over Northern Europe, causing widespread wind damage and more than 2 million Euros in economic loss in Estonia during its most destructive stage. This paper presents a modelling study of the derecho-producing storm utilising the Hirlam Aladin Research for Mesoscale Operational Numerical Weather Prediction in Europe (HARMONIE) model. The model setup is chosen to mimic near-future, nearly kilometre-scale, operational environments in European national weather services. The model simulations are compared to remote sensing and in situ observations. The HARMONIE model is capable of reproducing the wind gust severity and precipitation intensity. Moreover, 2.5-km grid spacing is shown to be sufficient for producing a reliable signal of the severe convective storm. Storm dynamics are well simulated, including the rear inflow jet. Although the model performance is promising, a strong dependence on the initial data, a weak trailing stratiform precipitation region and an incorrect timing of the storm are identified.

    HARMONI, the High Angular Resolution Monolithic Optical & Near-infrared Integral field spectrograph is one of two first-light instruments for the European Extremely Large Telescope. Over a 256x128 pixel field-of-view HARMONI will simultaneously measure approximately 32,000 spectra. Each spectrum is about 4000 spectral pixels long, and covers a selectable part of the 0.47-2.45 μm wavelength range at resolving powers of either R≍4000, 10000, or 20000. All 32,000 spectra are imaged onto eight HAWAII4RG detectors using a multiplexing scheme that divides the input field into four sub-fields, each imaged onto one image slicer that in turn re-arranges a single sub-field into two long exit slits feeding one spectrograph each. In total we require eight spectrographs, each with one HAWAII4RG detector. A system of articulated and exchangeable fold-mirrors and VPH gratings allows one to select different spectral resolving powers and wavelength ranges of interest while keeping a fixed geometry between the spectrograph collimator and camera avoiding the need for an articulated grating and camera. In this paper we describe both the field splitting and image slicing optics as well as the optics that will be used to select both spectral resolving power and wavelength range.

    Full Text Available Abstract Background The incidence of childhood type 1 diabetes (T1D incidence is rising in many countries, supposedly because of changing environmental factors, which are yet largely unknown. The purpose of the study was to unravel environmental markers associated with T1D. Methods Cases were children with T1D from the French Isis-Diab cohort. Controls were schoolmates or friends of the patients. Parents were asked to fill a 845-item questionnaire investigating the child’s environment before diagnosis. The analysis took into account the matching between cases and controls. A second analysis used propensity score methods. Results We found a negative association of several lifestyle variables, gastroenteritis episodes, dental hygiene, hazelnut cocoa spread consumption, wasp and bee stings with T1D, consumption of vegetables from a farm and death of a pet by old age. Conclusions The found statistical association of new environmental markers with T1D calls for replication in other cohorts and investigation of new environmental areas.

    Habitat classifications provide guidelines for mapping and comparing marine resources across geographic regions. Calcareous bio-concretions and their associated biota have not been exhaustively categorized. Furthermore, for management and conservation purposes, species and habitat mapping is critical. Recently, several developments have occurred in the field of predictive habitat modeling, and multiple methods are available. In this study, we defined the habitats constituting northern Adriatic biogenic reefs and created a predictive habitat distribution model. We used an updated dataset of the epibenthic assemblages to define the habitats, which we verified using the fuzzy k-means (FKM) clustering method. Redundancy analysis was employed to model the relationships between the environmental descriptors and the FKM membership grades. Predictive modelling was carried out to map habitats across the basin. Habitat A (opportunistic macroalgae, encrusting Porifera, bioeroders) characterizes reefs closest to the coastline, which are affected by coastal currents and river inputs. Habitat B is distinguished by massive Porifera, erect Tunicata, and non-calcareous encrusting algae (Peyssonnelia spp.). Habitat C (non-articulated coralline, Polycitor adriaticus) is predicted in deeper areas. The onshore-offshore gradient explains the variability of the assemblages because of the influence of coastal freshwater, which is the main driver of nutrient dynamics. This model supports the interpretation of Habitat A and C as the extremes of a gradient that characterizes the epibenthic assemblages, while Habitat B demonstrates intermediate characteristics. Areas of transition are a natural feature of the marine environment and may include a mixture of habitats and species. The habitats proposed are easy to identify in the field, are related to different environmental features, and may be suitable for application in studies focused on other geographic areas.

    The study aimed to evidence previous cases of legionellosis or proven or suspected pneumonia in seven hospital facilities for the mentally disabled in Northern Italy, where no clinical surveillance had been previously carried out. An additional aim was to highlight the occurrence of strains of Legionella pneumophila of clinical and environmental origin by Sequence-Based Typing (SBT), comparing them to world surveillance. A clinical survey was perfomed from 2003-2012, analyzing 615 medical records for hospital- and community-acquired pneumonia, with particular attention to legionellosis. Clinical (n=4) and environmental (n=25) isolates of Legionella pneumophila, isolated in the same period (2003-2012), were characterized by SBT and the Sequence Types (STs) compared with the European Working Group for Legionella Infections (EWGLI) database. Surveillance revealed that there were seven detected cases of legionellosis; most pneumonia cases could not be confirmed by diagnostic tests because of the disabilities of the patients and their lack of cooperation. The same ST was found in two of the clinical strains and also in a corresponding environment, i.e. ST685 and ST16, and two clinical strains belonging to the same ST (ST1). The other environmental strains were isolated in department with confirmed/suspected clinical cases. Five other STs found in this study were new to the database: ST685 was isolated both from a patient and from water; ST694, ST1181, ST1370 and ST1371 have not been described previously. The study confirmed that the routine collection and analysis of environmental strains may be an important strategy for preventing sporadic and epidemic cases of legionellosis, in association with clinical surveillance.

    Free-range use by broiler chickens is often limited, whereas better use of the free-range area could benefit animal welfare. Use of free-range areas could be stimulated by more appropriate shelter or environmental enrichment (by decreasing birds' fearfulness). This study aimed to assess the effects of shelter type, early environmental enrichment and weather conditions on free-range use. Three production rounds with 440 slow-growing broiler chickens (Sasso T451) were carried out. Birds were housed indoors in four groups (two with males, two with females) from days 0 to 25, during which two of the groups received environmental enrichment. At day 23 birds' fearfulness was assessed with a tonic immobility (TI) test (n=100). At day 25 all birds were moved (in mixed-sex groups) to mobile houses, and provided with free-range access from day 28 onwards. Each group could access a range consisting for 50% of grassland with 21 artificial shelters (ASs, wooden A-frames) and for 50% of short rotation coppice (SRC) with willow (dense vegetation). Free-range use was recorded by live observations at 0900, 1300 and 1700 h for 15 to 21 days between days 28 and 63. For each bird observed outside the shelter type (AS or SRC), distance from the house (0 to 2, 2 to 5, >5 m) and its behaviour (only rounds 2 and 3) were recorded. Weather conditions were recorded by four weather stations. On average, 27.1% of the birds were observed outside at any given moment of observation. Early environmental enrichment did not decrease fearfulness as measured by the TI test. It only had a minor effect on the percentage of birds outside (0.4% more birds outside). At all distances from the house, SRC was preferred over AS. In AS, areas closer to the house were preferred over farther ones, in SRC this was less pronounced. Free-range use increased with age and temperature and decreased with wind speed. In AS, rainfall and decreasing solar radiation were related to finding more birds outside, whereas the

    Clinical isolates of Legionella pneumophila, obtained from 167 patients, who acquired their illness in the community in England and Wales between January 2000 and March 2008, were compared with 276 environmental isolates of L. pneumophila obtained over the same period as part of the routine sampling of 'managed' water systems. The 443 isolates were typed by monoclonal antibody (mAb) subgrouping and the internationally standardised, seven-gene loci, sequence-based typing (SBT) scheme of the European Working Group for Legionella Infections (EWGLI). Of the clinical isolates, 97.6% were L. pneumophila serogroup (sgp) 1, compared with only 55.8% of environmental isolates (P = 0.0002); 91.6% were subgrouped as mAb3/1+ve, compared with only 8.3% of environmental isolates (P accounting for 25.7% and three (ST47, ST37 and ST62) accounting for 46.1% of all isolates. Eighty-two STs were identified among the environmental isolates, with two (ST1 and ST79) accounting for 34.1% of these. Comparison of the STs seen among clinical and environmental isolates showed that there was very little overlap between the two populations (P accounted for 22.8% of cases, but was only found once in the environment. Conversely, mAb 'Oxford/OLDA' ST1 was the most common environmental strain (17.0%), but only caused two infections. A review of the published data shows that mAb 'Allentown' ST47 is also an important cause of infection in France and possibly in the Netherlands. However, it was not found in a large study of German clinical isolates. This study confirms previous work showing that just a few strains of L. pneumophila cause the majority of community-acquired Legionella infection in England and Wales, and that these clinically significant strains are only rarely found in managed water systems. These data suggest that knowing which particular strain is present in an environment might be at least as important as knowing the quantity in which legionellae are present.

    Traditional village houses now use renewable materials and energy sources and this paper presents the intrinsic harmony of these buildings' greening and their sustainability. The paper covers building technical systems, sustainable energy supply, and the importance of renewable raw materials (RMS) for sustainable development. This study investigated the role of building dynamic behavior and optimized energy efficiency in reducing thermal loads significantly. A preliminary design for sustainable energy efficient settlements with net zero energy buildings is proposed and a comprehensive multidisciplinary engineering study was done which identified the technical feasibility of sustainable village energy and water supplies using solar or wind technologies. Overall, through analysis of sustainability definitions and possible ways to achieve sustainability, the study demonstrated that this can only be brought about by interdisciplinary interaction and finding the right balance between materiality and spirituality, science and art, and between technological development and concern for cultural and other human values.

    This article analyzes the links between the biological and social spheres established by Josué de Castro in his studies of alimentation. First it looks at how the author introduced modem dietary principles at the same time that hunger and malnutrition were unveiled in parts of Brazil, aiming at the configuration of a national alimentation policy. Second, at it examines how he expanded the debate, giving visibility to the dynamics of states and the political direction of a world that was being dismantled in which hunger and alimentation were an intrinsic part of the spatial distribution of power. In the postwar scenario the dietary principles of quantity, quality, harmony and adequacy were transposed as the guiding principles for a society without hunger at the global scale.

    When seeking near-optimal solutions for complex scheduling problems, meta-heuristics demonstrate good performance with affordable computational effort. This has resulted in a gravitation towards these approaches when researching industrial use-cases such as energy-efficient production planning. However, much of the previous research makes assumptions about softer constraints that affect planning strategies and about how human planners interact with the algorithm in a live production environment. This article describes a job-shop problem that focuses on minimizing energy consumption across a production facility of shared resources. The application scenario is based on real facilities made available by the Irish Center for Manufacturing Research. The formulated problem is tackled via harmony search heuristics with random keys encoding. Simulation results are compared to a genetic algorithm, a simulated annealing approach and a first-come-first-served scheduling. The superior performance obtained by the proposed scheduler paves the way towards its practical implementation over industrial production chains.

    Electric discharge machine (EDM) is one of the widely used nonconventional machining processes for hard and difficult to machine materials. Due to the large number of machining parameters in EDM and its complicated structural, the selection of the optimal solution of machining parameters for obtaining minimum machining performance is remain as a challenging task to the researchers. This paper proposed experimental investigation and optimization of machining parameters for EDM process on stainless steel 316L work piece using Harmony Search (HS) algorithm. The mathematical model was developed based on regression approach with four input parameters which are pulse on time, peak current, servo voltage and servo speed to the output response which is dimensional accuracy (DA). The optimal result of HS approach was compared with regression analysis and it was found HS gave better result y giving the most minimum DA value compared with regression approach.

    2014-06-01

    Full Text Available The behavior of gob-side entry under dynamic pressure is totally different from the one driven after the movement of overlying strata above the adjacent coalface goaf. The gob-side entry will experience severe roof lateral structural adjustments caused by adjacent coalface mining. Thus the deformation and failure characteristics of narrow coal pillar along the gob should be carefully considered. On the basis of the data of the gob-side entry obtained in a thin coal seam under dynamic pressure, the measures to reinforce the narrow coal pillar are put forward. In addition, the non-harmonious controlling of the rock structures and non-equilibrium gob-side entry deformation is proposed to avoid potential failure. Field practices show that the supporting problems of the gob-side entry under dynamic pressure can be well addressed, which could be used in other similar mining cases.

    The present research examined the background and consequences of different styles of engagement in video game play. Based on self-determination theory(1) and the dualistic model of passion,(2) the authors hypothesized that high levels of basic psychological need satisfaction would foster harmonious passion for video play, supporting the subjective sense that play is something one wants to do. It was also predicted that low levels of need satisfaction would promote obsessive passion for games and contribute to the feeling that game play is something one feels compelled to or has to do. It was expected, in turn, that passion for play would directly influence player outcomes closely tied to games, moderate links between play and well-being, and relate to overall levels of well-being as a function of basic need satisfaction. As expected, results showed that low levels of basic need satisfaction were associated with more obsessive passion, higher amounts of play, greater tension following play, and low game enjoyment, whereas high levels of need satisfaction did not predict hours of play but were associated with more harmonious passion, game enjoyment, and energy following play. Moderation analyses showed that high amounts of play related negatively to well-being only to the extent that players reported an obsessive passion and that the unique relations between passion and overall levels of player well-being were quite small once controlling for their basic need satisfaction in daily life. Discussion of the current findings focuses on their significance for understanding disordered play and the value of applying a theory-based approach to study motivation for virtual contexts.

    Full Text Available The study attempts to look at the existing inter-religious peace and harmony in Manado. The focus is an attempt to compare between Manado and Ambon which are similar in terms of demographic composition, historical background, political and cultural values but at the same time both are different; the former was in conflict, while the latter was an area of peace during the conflict escalation that engulfed some parts of East Indonesia. This study also tries to look at the strategy of Christian and Muslim communities in both cities in dealing with social tensions. In addition, this article specifically tries to explain factors that contribute to the presence of peace in Manado and its absence in Ambon. Subsequently, attention is also paid to the impact and mechanisms used by the elite in maintaining peace in Manado. This study uncovers some interesting findings. First, there are five elements that support the existence of peace in Manado: education, cultural values (local wisdom, economic situations, spiritual understanding, and the role of the elite. Second, inter-religious peace and harmony can exist in Manado, because of the synergy and cooperation of these three levels of leadership. Third, although the theory of Lederach seems to suggest that top-level leaders are the most dominant element of the elite, it is found that the role of grassroots leaders including leaders of congregations (imam, ustadz, clergymen, and priests is more vital as their more directly involved in the daily activities of the society. Fourth, the mechanisms of these elites seem to be various in every stage of leadership.

    To examine the effects of environmental noises (speech and white noise) relative to a no noise control condition on the performance and difficulty ratings of youth with ADHD (N = 52) on academic tasks. Reading performance was measured by an oral retell (reading accuracy) and the time spent reading. Writing performance was measured through the proportion of correct writing sequences (writing accuracy) and the total words written on an essay. Participants in the white noise condition took less time to read the passage and wrote more words on the essay compared with participants in the other conditions, though white noise did not improve academic accuracy. The participants in the babble condition rated the tasks as most difficult. Although white noise appears to improve reading time and writing fluency, the findings suggest that white noise does not improve performance accuracy. Educational implications are discussed. © 2015 SAGE Publications.

    Full Text Available The purpose of this study was to examine two biomass district heating plants operating in Tuscany, with a specific focus on the ex-post evaluation of their economic and financial feasibility and of their environmental benefits. The former biomass district heating plant supplies only public users (Comunità Montana della Lunigiana, CML: administrative body that coordinates the municipalities located in mountain areas, the latter supplies both public and private users (Municipality of San Romano in Garfagnana. Ex-post investment analysis was performed to check both the consistency of results with the forecasts made in the stage of the project design and on the factors, which may have reduced or jeopardized the estimated economic performance of the investment (ex-ante assessment. The results of the study point out appreciable results only in the case of biomass district heating plants involving private users and fuelled by biomasses sourced from third parties. In this case, the factors that most influence ex-post results include the conditions of the woody biomass local market (market prices, the policies of energy selling prices to private users and the temporal dynamics of private users’ connection. To ensure the consistency of ex-post economic outcome with the expected results it is thus important to: (i have good knowledge of the woody local market; (ii define energy selling prices that should be cheap for private users but consistent with energy production costs and (iii constrain private users beforehand to prevent errors in the plant design and in the preliminary estimate of return on investment. Moreover, the results obtained during the monitoring activities could help in providing information on the effectiveness of the supporting measures adopted and also to orient future choices of policy makers and particularly designers, to identify the most efficient configuration of district heating organization for improving energy and

    Highlights: • CO 2 /NH 3 cascade refrigeration cycles with flash intercoolers are investigated. • Exergoeconomic factors of components are determined to assess their relative significances. • An environmental analysis is applied to determine the penalty cost of GHG emission. • The effects of operating parameters on COP, exergy efficiency and total cost rate are investigated. • An optimization is applied based on the maximum COP and the minimum total cost rate. - Abstract: Exergoeconomic and environmental analyses are presented for two CO 2 /NH 3 cascade refrigeration systems equipped with (1) two flash tanks and (2) a flash tank along with a flash intercooler with indirect subcooler. A comparative study is performed for the proposed systems, and optimal values of operating parameters of the system are determined that maximize the coefficient of performance (COP) and exergy efficiency and minimize the total annual cost. The operating parameters considered include condensing temperatures of NH 3 in the condenser and CO 2 in the cascade heat exchanger, the evaporating temperature of CO 2 in the evaporator, the temperature difference in the cascade heat exchanger, the intermediate pressure of the flash tank in the CO 2 low-temperature circuit, the mass flow rate ratio in the flash intercooler and the degree of superheating of the CO 2 at the evaporator outlet. The total annual cost includes the capital, operating and maintenance costs and the penalty cost of GHG emission. The results show that, the total annual cost rate for system 1 is 11.2% and 11.9% lower than that for system 2 referring to thermodynamic and economic optimizations, respectively. For thermodynamic and cost optimal design condition the COP and exergy efficiency of both systems are almost the same. Finally, in order to obtain the best balance between exergy destruction cost and capital cost, the exergoeconomic factor is defined for each component of proposed systems, for cases in which the

    The present research quantifies the influence of source type and the presence of audible vibration-induced rattle on annoyance caused by vibration in residential environments. The sources of vibration considered are railway and the construction of a light rail system. Data were measured in the United Kingdom using a socio-vibration survey (N = 1281). These data are analyzed using ordinal logit models to produce exposure-response relationships describing community annoyance as a function of vibration exposure. The influence of source type and the presence of audible vibration-induced rattle on annoyance are investigated using dummy variable analysis, and quantified using odds-ratios and community tolerance levels. It is concluded that the sample population is more likely to express higher levels of annoyance if the vibration source is construction compared to railway, and if vibration-induced rattle is audible.

    Full Text Available Abstract Since the Assisi Declarations on man and nature were initially created by leaders from Buddhism, Christianity, Hinduism, Islam and Judaism at an interreligious meeting convened by World Wildlife Fund in Assisi, Italy in September 1986 and the first World Day of Prayer for Peace attended by representatives of many more faiths and ethnic religions in October 1986 in Assisi, a contemporary environmental movement that clearly encompasses spiritual as well as social dimensions has been growing exponentially. However, given the acceleration of global warming and environmental crises differentially affecting parts of the earth, we have now to ask, what is the application of the Assisi Declarations and peace prayers for facing the needs of today and in the future? This article thus aims to convey some ideas on the contributions of living prayer and associated creative practices in Indonesia in general, and Bali in particular, by discussing three dimensions: (a the ways in which living prayer is embodied in customary ritual arts as well as in new forms of artistic expression; (b its contributions to environmental, socio-cultural, and economic well-being; and (c the means by which it fosters intercultural and interreligious dialogue and creativity. To illustrate this, I draw on examples of prayers and art from public participatory intercultural Sharing Art events held in Bali and Java as well as in other countries.

    The bacterial pathogen Vibrio cholerae can occupy both the human gut and aquatic reservoirs, where it may colonize chitinous surfaces that induce the expression of factors for three phenotypes: chitin utilization, DNA uptake by natural transformation, and contact-dependent bacterial killing via a type VI secretion system (T6SS). In this study, we surveyed a diverse set of 53 isolates from different geographic locales collected over the past century from human clinical and environmental specimens for each phenotype outlined above. The set included pandemic isolates of serogroup O1, as well as several serogroup O139 and non-O1/non-O139 strains. We found that while chitin utilization was common, only 22.6% of the isolates tested were proficient at chitin-induced natural transformation, suggesting that transformation is expendable. Constitutive contact-dependent killing of Escherichia coli prey, which is indicative of a functional T6SS, was rare among clinical isolates (only 4 of 29) but common among environmental isolates (22 of 24). These results bolster the pathoadaptive model in which tight regulation of T6SS-mediated bacterial killing is beneficial in a human host, whereas constitutive killing by environmental isolates may give a competitive advantage in natural settings. Future sequence analysis of this set of diverse isolates may identify previously unknown regulators and structural components for both natural transformation and T6SS.

    Trichosporon asahii, which is distributed in the environment, is the major causative agent of the opportunistic infection trichosporonosis, and it also causes summer-type hypersensitivity pneumonitis (SHP). Random amplification of polymorphic DNA analysis was used to determine the intraspecies diversity of 39 T. asahii isolates from clinical specimens, SHP patients' houses, and environmental materials. The three primers used revealed 46 polymorphic bands. A phenogram was generated by the unweighted pair-group method with arithmetic mean. Clinical isolates formed a cluster, characterized by a 90% matching coefficient, but they did not cluster with strains isolated from SHP patients' houses or environmental sources. In addition, the biochemical characteristics of 86 strains from three sources were examined with 31 compounds using an ID32C kit, and a phenogram was constructed. The phenogram consisted of three major clusters. Cluster I included most of the clinical SHP isolates, and cluster II included most of the environmental isolates. Cluster III contained only one strain. A remarkable difference was found in the abilities of the strains belonging to clusters I and II to utilize six compounds. These results suggest that the genetic diversity and biochemical characteristics of T. asahii seem to be related to the source of the isolate. We also found a specific DNA fragment for the clinical isolates and strains isolated from SHP patients' houses. PMID:11427546

    The efficiency of the extraction and removal of pollutants from food and the environment has been an important issue in analytical science. By incorporating inorganic species into an organic matrix, a new material known as an organic-inorganic hybrid material is formed. As it possesses high selectivity, permeability, and mechanical and chemical stabilities, organic-inorganic hybrid materials constitute an emerging research field and have become popular to serve as sorbents in various separaton science methods. Here, we review recent significant advances in analytical solid-phase extraction employing organic-inorganic composite/nanocomposite sorbents for the extraction of organic and inorganic pollutants from various types of food and environmental matrices. The physicochemical characteristics, extraction properties, and analytical performances of sorbents are discussed; including morphology and surface characteristics, types of functional groups, interaction mechanism, selectivity and sensitivity, accuracy, and regeneration abilities. Organic-inorganic hybrid sorbents combined with extraction techniques are highly promising for sample preparation of various food and environmental matrixes with analytes at trace levels. © 2017 WILEY-VCH Verlag GmbH & Co.

    Against the backdrop of increasing interest in the relationship between Nature and health, this study examined the effect of perceived environment type and indicators of perceived environmental quality on short-term emotional well-being following outdoor group walks. Participants (n = 127) of a national group walk program completed pre- and post-walk questionnaires for each walk attended (n = 1009) within a 13-week study period. Multilevel linear modelling was used to examine the main and moderation effects. To isolate the environmental from the physical activity elements, analyses controlled for walk duration and perceived intensity. Analyses revealed that perceived restorativeness and perceived walk intensity predicted greater positive affect and happiness following an outdoor group walk. Perceived restorativeness and perceived bird biodiversity predicted post-walk negative affect. Perceived restorativeness moderated the relationship between perceived naturalness and positive affect. Results suggest that restorative quality of an environment may be an important element for enhancing well-being, and that perceived restorativeness and naturalness of an environment may interact to amplify positive affect. These findings highlight the importance of further research on the contribution of environment type and quality on well-being, and the need to control for effects of physical activity in green exercise research.

    Full Text Available Desiccant-based air handling units can achieve reductions in greenhouse gas emissions and energy savings with respect to conventional air conditioning systems. Benefits are maximized when they interact with renewable energy technologies, such as solar collectors. In this work, experimental tests and data derived from scientific and technical literature are used to implement a model of a solar desiccant cooling system, considering three different collector technologies (air, flat-plate and evacuated collectors. Simulations were then performed to compare the energy, environmental and economic performance of the system with those of a desiccant-based unit where regeneration thermal energy is supplied by a natural gas boiler, and with those of a conventional air-handling unit. The only solution that allows achieving the economic feasibility of the solar desiccant cooling unit consists of 16 m2 of evacuated solar collectors. This is able to obtain, with respect to the reference system, a reduction of primary energy consumption and of the equivalent CO2 emissions of 50.2% and 49.8%, respectively, but with a payback time of 20 years.

    Full Text Available Decorated glazed ceramic tiles are used as an ornamental art, constituting an important cultural heritage whose preservation is mandatory. Environmental conditions are responsible for the degradation of exposed ancient tile panels originating various pathologies, related to the development of microorganisms. This is the case of a valuable 18th century blue-and-white Portuguese tile panel called “Cura do Cego,” belonging to the collection of the National Tile Museum (MNAz, where green stains are nowadays observable in the glaze. A prospective diagnosis of this green tarnishing was the aim of the present work. Small tile fragments were directly irradiated using nondestructive techniques: X-ray fluorescence spectrometry with a wavelength-dispersive system (WDXRF for chemical characterization of the tile glaze and X-ray powder diffraction (XRD to assess the phase constitution of both the glaze and the ceramic body. A destructive technique (scanning electron microscopy with energy-dispersive system (SEM/EDS was applied to tentatively infer the chemical changes induced in the glaze by the green staining and also to characterize the morphology of the microorganisms associated to this staining. The obtained results are reported and discussed, as a preliminary step for testing an innovative nondestructive decontamination technique applying gamma radiation, particularly suitable for overcoming such tile pathologies.

    The analysis of drugs in various biological fluids is an important criterion for the determination of the physiological performance of a drug. After sampling of the biological fluid, the next step in the analytical process is sample preparation. Sample preparation is essential for isolation of desired components from complex biological matrices and greatly influences their reliable and accurate determination. The complexity of biological fluids adds to the challenge of direct determination of the drug by chromatographic analysis, therefore demanding a sample preparation step that is often time consuming, tedious and frequently overlooked. However, direct online injection methods offer the advantage of reducing sample preparation steps and enabling effective pre-concentration and clean-up of biological fluids. These procedures can be automated and therefore reduce the requirements for handling potentially infectious biomaterial, improve reproducibility, and minimize sample manipulations and potential contamination. This review is focused on the discovery and development of high-performance liquid chromatography (HPLC) and gas chromatography (GC) with different detectors. The drugs covered in this review are antiepileptics, antidepressant (AD), and quinolones. The application of these methods for determination of these drugs in biological, environmental and pharmaceutical samples has also been discussed.

    The aim of the present study was to determine the genetic relatedness of strains isolated from diarrhoeal stool and water specimens collected from water-storage containers from different geographical areas in the Limpopo province. In total, 32 Aeromonas strains isolated from stool specimens collected from HIV/AIDS patients suffering from gastroenteritis and their household drinking-water stored in 20-L and 25-L containers were analyzed by random amplified polymorphic DNA PCR (RAPD). The RAPD fingerprints obtained proved reproducible when repeated on three different occasions using whole-cell DNA isolated from the Aeromonas strains. In total, 12 unique RAPD fingerprints were found. The results revealed a tendency of the isolates to cluster according to their origin of isolation (best-cut test 0.80 and bootstrap values >50%). However, a certain degree of similarity was also observed between isolates of water sources and clinical sources which indicated genetic relatedness. There were also genetic similarities between the clinical and the environmental strains of Aeromonas spp. isolated from different geographical areas. This study has demonstrated the genetic relatedness of Aeromonas hydrophila isolates from household drinking-water and clinical sources in South Africa, which may be due to cross-contamination from water to patients or vice-versa. This observation is of public-health significance, particularly in the era of HIV/AIDS. This study points to the importance of monitoring and evaluating infection-control measures for improved hygiene and to prevent cross-contaminations.

    In a recent study of polyketide biosynthetic gene clusters cloned directly from soil, we isolated two antibiotics, fasamycins A and B, which showed activity against methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecalis. To identify the target of the fasamycins, mutants with elevated fasamycin A minimum inhibitory concentrations were selected from a wild-type culture of E. faecalis OG1RF. Next-generation sequencing of these mutants, in conjunction with in vitro biochemical assays, showed that the fasamycins inhibit FabF of type II fatty acid biosynthesis (FASII). Candidate gene overexpression studies also showed that fasamycin resistance is conferred by fabF overexpression. On the basis of comparisons with known FASII inhibitors and in silico docking studies, the chloro-gem-dimethyl-anthracenone substructure seen in the fasamycins is predicted to represent a naturally occurring FabF-specific antibiotic pharmacophore. Optimization of this pharmacophore should yield FabF-specific antibiotics with increased potencies and differing spectra of activity. This study demonstrates that culture-independent antibiotic discovery methods have the potential to provide access to novel metabolites with modes of action that differ from those of antibiotics currently in clinical use.

    Full Text Available Takotsubo syndrome (TS is a heart condition characterised by a sudden transient left ventricular dysfunction; its pathophysiology is probably associated with elevated levels of catecholamines but the exact mechanism is not known as yet. Literature and clinical experience suggest that TS affects persons with various comorbidities. This pilot work aims to evaluate the frequency of comorbidities with potential pathological immune reactivity, and to evaluate the potential association between TS and hypersensitivity to metals assessed by LTT-MELISA®.A total of 24 patients (23 women, 1 man with a history of TS attack and 27 healthy controls were evaluated. Hypersensitivity was evaluated by a lymphocyte transformation test (LTT-MELISA®; a questionnaire of environmental burden was used to select evaluated metals. A total of 19 patients (79% had at least one condition that might potentially be associated with pathological immune reactivity (autoimmune thyroid disease, drug allergy, bronchial asthma, cancer, contact dermatitis, rheumatoid arthritis. Hypersensitivity to metals was identified significantly more frequently in TS patients than in healthy controls (positive reaction to at least one metal was identified in 95.8% of TS patients and in 59.3% of controls; p = 0.003; the difference was statistically significant for mercury (45.8% and 14.8%, respectively; p = 0.029.Our work shows that conditions with pathological immune reactivity occur frequently in TS patients, and our data suggest a possible association between TS and hypersensitivity to metals (mercury in particular evaluated by LTT-MELISA®. We also suggest that apart from the triggering stress factor, potential existence of other serious conditions should be considered when taking medical history of TS patients.

    Full Text Available Vaccine derived poliovirus (VDPV type 2 strains strongly divergent from the corresponding vaccine strain, Sabin 2, were repeatedly isolated from sewage in Slovakia over a period of 22 months in 2003-2005. Cell cultures of stool specimens from known immune deficient patients and from an identified putative source population of 500 people failed to identify the potential excretor(s of the virus. The occurrence of VDPV in sewage stopped without any intervention. No paralytic cases were reported in Slovakia during the episode. According to a GenBank search and similarity plotting-analysis, the closest known relative of the first isolate PV2/03/SVK/E783 through all main sections of the genome was the type 2 poliovirus Sabin strain, with nucleotide identities in 5'UTR, P1, P2, P3, and 3'UTR parts of the genome of 88.6, 85.9, 87.3, 88.5, and 94.0 percent, respectively. Phenotypic properties of selected Slovakian aVDPV strains resembled those of VDPV strains isolated from immune deficient individuals with prolonged PV infection (iVDPV, including antigenic changes and moderate neurovirulence in the transgenic mouse model. One hundred and two unique VP1 coding sequences were determined from VDPV strains isolated from 34 sewage specimens. Nucleotide differences from Sabin 2 in the VP1 coding region ranged from 12.5 to 15.6 percent, and reached a maximum of 9.6 percent between the VDPV strains under study. Most of the nucleotide substitutions were synonymous but as many as 93 amino acid positions out of 301 in VP1 showed substitutions. We conclude that (1 individuals with prolonged poliovirus infection are not as rare as suggested by the studies on immune deficient patients known to the health care systems and (2 genetic divergence of VDPV strains may remain extensive during years long replication in humans.

    Between 1978 and 2008, 13 avian botulism outbreaks were recorded in the wetlands of Mancha Húmeda (central Spain). These outbreaks caused the deaths of around 20,000 birds from over 50 species, including globally endangered white-headed ducks (Oxyura leucoceophala). Here, a significant association was found between the number of dead birds recorded in each botulism outbreak and the mean temperature in July (always >26°C). The presence of Clostridium botulinum type C/D in wetland sediments was detected by real-time PCR (quantitative PCR [qPCR]) in 5.8% of 207 samples collected between 2005 and 2008. Low concentrations of Cl(-) and high organic matter content in sediments were significantly associated with the presence of C. botulinum. Seventy-five digestive tracts of birds found dead during botulism outbreaks were analyzed; C. botulinum was present in 38.7% of them. The prevalence of C. botulinum was 18.2% (n = 22 pools) in aquatic invertebrates (Chironomidae and Corixidae families) and 33.3% (n = 18 pools) in necrophagous invertebrates (Sarcophagidae and Calliphoridae families), including two pools of adult necrophagous flies collected around bird carcasses. The presence of the bacteria in the adult fly form opens up new perspectives in the epidemiology of avian botulism, since these flies may be transporting C. botulinum from one carcass to another.

    The abandoned Valzinco mine, which worked a steeply dipping Kuroko-type massive sulfide deposit in the Virginia Au-pyrite belt, contributed significant metal-laden acid-mine drainage to the Knight's Branch watershed. The host rocks were dominated by metamorphosed felsic volcanic rocks, which offered limited acid-neutralizing potential. The ores were dominated by pyrite, sphalerite, galena, and chalcopyrite, which represented significant acid-generating potential. Acid-base accounting and leaching studies of flotation tailings - the dominant mine waste at the site - indicated that they were acid generating and therefore, should have liberated significant quantities of metals to solution. Field studies of mine drainage from the site confirmed that mine drainage and the impacted stream waters had pH values from 1.1 to 6.4 and exceeded aquatic ecosystem toxicity limits for Fe, Al, Cd, Cu, Pb and Zn. Stable isotope studies of water, dissolved SO42 -, and primary and secondary sulfate and sulfide minerals indicated that two distinct sulfide oxidation pathways were operative at the site: one dominated by Fe(III) as the oxidant, and another by molecular O2 as the oxidant. Reaction-path modeling suggested that geochemical interactions between tailings and waters approached a steady state within about a year. Both leaching studies and geochemical reaction-path modeling provided reasonable predictions of the mine-drainage chemistry.

    A real-time PCR method for detection and typing of BoNT-producing Clostridia types A, B, E, and F was developed on the framework of the European Research Project "Biotracer". A primary evaluation was carried out using 104 strains and 17 clinical and food samples linked to botulism cases. Results showed 100% relative accuracy, 100% relative sensitivity, 100% relative specificity, and 100% selectivity (inclusivity on 73 strains and exclusivity on 31 strains) of the real-time PCR against the reference cultural method combined with the standard mouse bioassay. Furthermore, a ring trial study performed at four different European laboratories in Italy, France, the Netherlands, and Sweden was carried out using 47 strains, and 30 clinical and food samples linked to botulism cases. Results showed a concordance of 95.7% among the four laboratories. The reproducibility generated a relative standard deviation in the range of 2.18% to 13.61%. Considering the high level of agreement achieved between the laboratories, this real-time PCR is a suitable method for rapid detection and typing of BoNT-producing Clostridia in clinical, food and environmental samples and thus support the use of it as an international standard method.

  7. Environmental Dependence of Type Ia Supernova Luminosities from a Sample without a Local–Global Difference in Host Star Formation

    It is established that there is a dependence of the luminosity of type Ia supernovae (SNe Ia) on environment: SNe Ia in young, star-forming, metal-poor stellar populations appear fainter after light-curve shape corrections than those in older, passive, metal-rich environments. This is accounted for in cosmological studies using a global property of the SN host galaxy, typically the host galaxy stellar mass. However, recent low-redshift studies suggest that this effect manifests itself most strongly when using the local star formation rate (SFR) at the SN location, rather than the global SFR or the stellar mass of the host galaxy. At high-redshift, such local SFRs are difficult to determine; here, we show that an equivalent local correction can be made by restricting the SN Ia sample in globally star-forming host galaxies to a low-mass host galaxy subset (≤1010 M ⊙). Comparing this sample of SNe Ia (in locally star-forming environments) to those in locally passive host galaxies, we find that SNe Ia in locally star-forming environments are 0.081 ± 0.018 mag fainter (4.5σ), consistent with the result reported by Rigault et al., but our conclusion is based on a sample ∼5 times larger over a wider redshift range. This is a larger difference than when splitting the SN Ia sample based on global host galaxy SFR or host galaxy stellar mass. This method can be used in ongoing and future high-redshift SN surveys, where local SN Ia environments are difficult to determine.

    This study determined environmental pH changes after root canal dressing using 3 types of commercial calcium hydroxide pastes. Thirty-two extracted single-rooted human premolars with 1 straight root canal were selected. Standard cavities were prepared on root surfaces. All root surfaces, excluding the cavities, were covered with nail polish. Root canals were prepared using the Easy RaCe rotary system. The teeth were randomly divided into 3 experimental groups filled with calcium hydroxide pastes: (Group 1) Sure-Paste, (Group 2) Meta-Paste, and (Group 3) Multi-Cal. The control group had 2 samples. Teeth were then placed in 10 mL of normal saline. Environmental pH values were measured at 1 h, 24 h, 48 h, and 1 week. Statistical evaluations of the results were performed via the ANOVA and Tukey tests. Results demonstrated that groups 3 and 1 showed a significant statistical difference (PpH being greater in group 3. There was no significant difference between groups 2 and 3 (P>.05). Intracanal placement of Multi-Cal compared with that of Sure-Paste and Meta-Paste resulted in a higher pH in simulated root resorption defects. In cases, like apexification, that need longer pH changes and higher disinfecting qualities, it might be better to use Multi-Cal, and for short-time use as disinfectant medicament Multi-Cal and Meta-Paste are equally effective.

    A method for the extraction of nucleic acids from a wide range of environmental samples was developed. This method consists of several modules, which can be individually modified to maximize yields in extractions of DNA and RNA or separations of DNA pools. Modules were designed based on elaborate tests, in which permutations of all nucleic acid extraction steps were compared. The final modular protocol is suitable for extractions from igneous rock, air, water, and sediments. Sediments range from high-biomass, organic rich coastal samples to samples from the most oligotrophic region of the world's oceans and the deepest borehole ever studied by scientific ocean drilling. Extraction yields of DNA and RNA are higher than with widely used commercial kits, indicating an advantage to optimizing extraction procedures to match specific sample characteristics. The ability to separate soluble extracellular DNA pools without cell lysis from intracellular and particle-complexed DNA pools may enable new insights into the cycling and preservation of DNA in environmental samples in the future. A general protocol is outlined, along with recommendations for optimizing this general protocol for specific sample types and research goals. PMID:26042110

  12. AvrRxo1 Is a Bifunctional Type III Secreted Effector and Toxin-Antitoxin System Component with Homologs in Diverse Environmental Contexts.

    Directory of Open Access Journals (Sweden)

    Lindsay R Triplett

    Full Text Available Toxin-antitoxin (TA systems are ubiquitous bacterial systems that may function in genome maintenance and metabolic stress management, but are also thought to play a role in virulence by helping pathogens survive stress. We previously demonstrated that the Xanthomonas oryzae pv. oryzicola protein AvrRxo1 is a type III-secreted virulence factor that has structural similarities to the zeta family of TA toxins, and is toxic to plants and bacteria in the absence of its predicted chaperone Arc1. In this work, we confirm that AvrRxo1 and its binding partner Arc1 function as a TA system when expressed in Escherichia coli. Sequences of avrRxo1 homologs were culled from published and newly generated phytopathogen genomes, revealing that avrRxo1:arc1 modules are rare or frequently inactivated in some species and highly conserved in others. Cloning and functional analysis of avrRxo1 from Acidovorax avenae, A. citrulli, Burkholderia andropogonis, Xanthomonas translucens, and Xanthomonas euvesicatoria showed that some AvrRxo1 homologs share the bacteriostatic and Rxo1-mediated cell death triggering activities of AvrRxo1 from X. oryzae. Additional distant putative homologs of avrRxo1 and arc1 were identified in genomic or metagenomic sequence of environmental bacteria with no known pathogenic role. One of these distant homologs was cloned from the filamentous soil bacterium Cystobacter fuscus. avrRxo1 from C. fuscus caused watersoaking and triggered Rxo1-dependent cell collapse in Nicotiana benthamiana, but no growth suppression in E. coli was observed. This work confirms that a type III effector can function as a TA system toxin, and illustrates the potential of microbiome data to reveal new environmental origins or reservoirs of pathogen virulence factors.

  13. Study of the type of gamma radioactivity in platform carbonaceous rocks: analyses and environmental, diagenetic and geodynamical interpretations

    In well-logging, values of gamma-activity are measured by scintillometry. A conventional paradigm is to link high γ-activity to Potassium (K) and Thorium (Th) isotopes present in clays and to Uranium isotopes present either in detrital sediments (typically in zircon or monazite minerals) or to sediments rich in organic matter. In shallow-water carbonates platforms, high γ-activities are interpreted in the same way. However, in a first γ-scintillometer survey of the Gorges du Nan section (sub-alpine Vercors massif), we found inconsistencies between lithologies and their expected γ-responses: the highest radioactive beds do not correspond to high argillaceous or detrital limestones and marls, but to some low content argillaceous or 'pure' limestones beds. The aim of this study was to identify the radioactive isotopes associated to different types of carbonates, their localisation, their abundance and their respective contribution to the total gamma response in order to propose a new method for the interpretation of gamma-ray logs in shallow-water carbonates. This study was focused on two intervals: - The first one corresponds to the Ba3 depositional sequence (Upper Barremian) which is composed essentially of limestones. This sequence was studied in the Vercors and Chartreuse sub-alpine massifs near Grenoble and in the Swiss Jura near Neuchatel; - The second one corresponds to the 'Lower Oritolina marls' interval. This interval was studied in the Vercors and Chartreuse sub-alpine massifs near Grenoble, in Spain (Organya basin) and in central Tunisia near Kairouan. We carried out detailed sedimentological, diagenetic and isotopic studies of all these sections. Oxygen and carbon stable isotopes analyses allowed us to establish some large scale correlations between sections in the French Alps, in the Pyrenees and in central Tunisia. The good correlation between Oxygen and Carbon stable isotopes curves of the Lower Orbitolina marls in all the

    Full Text Available In the field of health losses resulting from failure to establish the facilities in a suitable location and the required number, beyond the cost and quality of service will result in an increase in mortality and the spread of diseases. So the facility location models have special importance in this area. In this paper, a successively inclusive hierarchical model for location of health centers in term of the transfer of patients from a lower level to a higher level of health centers has been developed. Since determination the exact number of demand for health care in the future is difficult and in order to make the model close to the real conditions of demand uncertainty, a fuzzy programming model based on credibility theory is considered. To evaluate the proposed model, several numerical examples are solved in small size. In order to solve large scale problems, a meta-heuristic algorithm based on harmony search algorithm was developed in conjunction with the GAMS software which indicants the performance of the proposed algorithm.

    Full Text Available Purpose: assess the influence of a therapy conducted according to the Belgian School on the psychomotor development of children suffering from developmental dissonance. Material and methods: the studies involved 32 six yrs. old children, having symptoms of developmental dissonance, who qualified for Belgian psychomotor therapy and who came from different areas in Poland. Two measurements of the selected areas of the psychomotor field have been performed using the following tests: MOT 4-6 by R. Zimmer and M. Volkammer; PST 6-8 by S. Naville and A. Weber, B. Mock; WET 3-6 by P. Deimann and U. Kastner-Koller , as well as SCSIT by J. Ayres. The undertaken studies lasted for approximately 6 months and were a pedagogic quasi-experiment in nature. Results: upon the conclusion of experimental factor’s influence i.e. the Belgian psychomotor therapy, it has been observed that in the study pertaining to the psychomotor development, the results obtained by the six-year-old children cease to significantly differ from the values obtained by their peers, displaying no symptoms of dissonance. Conclusion: psychomotor therapy according to the Belgian School is a useful method of alleviating the symptoms of a non-harmonious development of a six-year-old child. A scientific confirmation of the research problem’s significance can facilitate therapist’s work. The results of the research will also contribute to the development of knowledge about diagnosis of developmental dissonance and Belgian psychomotor therapy.

  16. Comparison of multiobjective harmony search, cuckoo search and bat-inspired algorithms for renewable distributed generation placement

    Full Text Available Electric power losses have a significant impact on the total costs of distribution networks. The use of renewable energy sources is a major alternative to improve power losses and costs, although other important issues are also enhanced such as voltage magnitudes and network congestion. However, determining the best location and size of renewable energy generators can be sometimes a challenging task due to a large number of possible combinations in the search space. Furthermore, the multiobjective functions increase the complexity of the problem and metaheuristics are preferred to find solutions in a relatively short time. This paper evaluates the performance of the cuckoo search (CS, harmony search (HS, and bat-inspired (BA algorithms for the location and size of renewable distributed generation (RDG in radial distribution networks using a multiobjective function defined as minimizing the energy losses and the RDG costs. The metaheuristic algorithms were programmed in Matlab and tested using the 33-node radial distribution network. The three algorithms obtained similar results for the two objectives evaluated, finding points close to the best solutions in the Pareto front. Comparisons showed that the CS obtained the minimum results for most points evaluated, but the BA and the HS were close to the best solution.

    The paper traces 30 years of commitment to environmental values of tourism by the intergovernmental World Tourism Organization. Such commitment was almost unfashionable in the 1950s but gradually what began as an article of faith was vindicated by results of market research showing that the protection, enhancement and improvement of man's physical and human environment were among the fundamental requirements for the harmonious development of tourism. The establishment of the United Nations Environmental Program at last gave WTO a partner with the necessary authority with which the world body could walk towards mutually agreed goals.

    The global epidemics of type 2 diabetes and obesity have been attributed to the interaction between lifestyle changes and genetic predisposition to these diseases. We compared the prevalences of type 2 diabetes and obesity in Mexican Pima Indians, presumed to have a high genetic predisposition to these diseases, to those in their non-Pima neighbors, both of whom over a 15-year period experienced a transition from a traditional to a more modern lifestyle. Prevalence of diabetes, impaired fasting glucose, impaired glucose tolerance, and obesity in Mexican Pimas (n = 359) and non-Pima Mexicans (n = 251) were determined in 2010 using methods identical to those used in 1995. During this 15-year period, age-adjusted diabetes prevalence was unchanged in Pima men (5.8% in 1995 vs. 6.1% in 2010) yet increased in non-Pima men from 0.0 to 8.6% (P obesity increased significantly in all groups (6.6 vs. 15.7% in Pima men; 8.5 vs. 20.5% in non-Pima men; 18.9. vs 36.3% in Pima women; 29.5 vs. 42.9% in non-Pima women). Type 2 diabetes prevalence increased between 1995 and 2010 in non-Pima men, and to a lesser degree in women of both groups, but it did not increase in Pima men. Prevalence of obesity increased among Pimas and non-Pimas of both sexes. These changes occurred concomitantly with an environmental transition from a traditional to a more modernized lifestyle. © 2015 by the American Diabetes Association.

    The Fukushima NPP accident caused a small but detectable cesium fallout in northern Finland, of the order of 1 Bq/m(2). This fallout transferred further to soil, water, flora and fauna. By using modern HPGe detector systems traces of (134)Cs from the Fukushima fallout were observed in various samples of biota. In northern Finland different types of environmental samples such as reindeer meat, berries, fish, lichens and wolf were collected during 2011-2013. The observed (134)Cs concentrations varied from 0.1 Bq/kg to a few Bq/kg. By using the known (134)Cs/(137)Cs ratio observed in Fukushima fallout the increase of the Fukushima accident to the (137)Cs concentrations was found to vary from 0.06 % to 6.9 % depending on the sample type. The aggregated transfer factors (Tag) and effective half-lives (Teff) for (134)Cs and (137)Cs were also determined and then compared with known values found from earlier studies which are calculated based on the fallout from the Chernobyl accident. Generally, the Tag and Teff values determined in this study were found to agree with the values found in the earlier studies. The Teff values were sample-type specific and were found to vary from 0.91 to 2.1 years for (134)Cs and the estimates for (137)Cs ranged between 1.6 and 19 years. Interestingly, the ground lichens had the longest Teff whereas the beard lichen had the shortest. In fauna, highest Tag values were determined for wolf meat ranging between 1.0 and 2.2 m(2)/kg. In flora, the highest Tag values were determined for beard lichens, ranging from 1.9 m(2)/kg to 3.5 m(2)/kg. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The anti-malarial drug, artemisinin, is quite expensive as a result of its slow content in Artemisia annua. Recent investigations have suggested that genetic engineering of A. annua is a promising approach to improve the yield of artemisinin. In this study, the transgenic A. annua strain GYR, which has high artemisinin content, was evaluated in an environmental release trial. First, GYR plants were compared with the wild-type variety NON-GYR, with regard to phenotypic characters (plant height, crown width, stem diameter, germination rate, leaf dry weight, 1000-seed weight, leave shape). Second, stress resistance in the two varieties (salt, drought, herbicide, and cold resistance) was evaluated under different experimental conditions. Finally, gene flow was estimated. The results indicated that there were significant differences in several agronomic traits (plant height, stem diameter, and leave dry weight) between the transgenic GYR and NON-GYR plants. Salt stress in transgenic and control plants was similar, except under high NaCl concentrations (1.6%, w/w). Leaf water, proline, and MDA content (increased significantly) were significantly different. Transgenic A. annua GYR plants did not grow better than NON-GYR plants with respect to drought and herbicide resistance. The two varieties maintained vitality through the winter. Third, gene flow was studied in an environmental risk trial for transgenic GYR. The maximum gene flow frequency was 2.5%, while the maximum gene flow distance was 24.4 m; gene flow was not detected at 29.2 m at any direction. Our findings may provide an opportunity for risk assessment in future commercialization of transgenic A. annua varieties.

    Mali has long been affected by migration because of its location between North Africa and sub-Saharan Africa. Around 80% of the population depends on agriculture or herding for its livelihood. During the rainy season, from June-October, most of the population is busy in agricultural work, but during the dry season from November to May seasonal migration in search of wage employment is common. Seasonal migration is also part of the long tradition of commerce with neighboring countries. Economic difficulties of the last several years have encourage migration to urban centers and foreign countries. The drought that has afflicted Mali for over a decade is a further impetus to migration. 2 types of migration can be distinguished in Mali, shortterm movements of nomads and seasonal migration lasting less than 6 months, and definitive movements lasting longer including rural-urban and international migration. 4 further categories of migration include rural-rural movements especially in the south and in areas of industrial development, rural-urban migrations which are 1 of the most important factors in rapid urban growth especially around Bamako,, urban-urban migration essentially reflecting step migration from rural areas to secondary urban centers and finally to large cities, and urban-rural migration which occurs much less frequently. Over 80% of temporary movements take place within Mali. About 80% of those residing temporarily outside Mali are men. Temporary migrants inside Mali are oriented from the north to the region of Sikasso and the District of Bamako in the south and primarily are young men aged 15-29. There has been a progressive decline in the proportion of nomads in the general population from 7% in 1976 to 4% in 1987. There has been an increase in definitive migration from areas less favored ecologically to more desirable areas. A 1985 demographic survey found that 21% of the population aged 15 or over were migrants. 51.4% of migrants were male. 86% cited

    This survey arranged the status of coal utilization technology and the status of coal production, supply, etc. in Malaysia and Vietnam, examined/studied coal utilization systems in both countries, and finally assessed feasibility of introducing the environmentally friendly type coal utilization system. As a country of primary energy source which is abundant in crude oil, natural gas, hydroelectric power, coal, etc., Malaysia now depends on crude oil and natural gas for 80% of its energy, and places emphasis on exploration of natural gas and oil refining. In electric power and cement industries where coal is consumed, effectiveness and environmental issues in association with coal utilization are future subjects. In Vietnam, the north is abundant in hydroelectric power and anthracite, and the south in oil and gas resource, but the north and central districts are in a state of undevelopment. Coal is used for coal thermal power generation, cement industry, and residential/commercial fuel. In the future, effective coal utilization and environmental issues will be subjects. 16 refs., 38 figs., 75 tabs.

    Statistical post-processing of deterministic weather forecasts allows production of the full forecast distribution, and thus probabilistic forecasts, to be derived from that deterministic model output. We focus on local extreme precipitation amounts, as these are one predictand used in the KNMI weather warning system. As such, the predictand is based on the maximum hourly calibrated radar precipitation in a 3x3 km2 area within 12 large regions covering The Netherlands in a 6-hour afternoon period in summer (12-18 UTC). We compare three statistical methods when post-processing output from the operational high-resolution forecast model at KNMI, HARMONIE. These methods are 1) extended logistic regression (ELR), 2) an ensemble model output statistics approach where the parameters of a zero-adjusted gamma (ZAGA) distribution depends on a set of covariates and 3) quantile random forests (QRF). The set of predictors used as covariates includes model precipitation and indices capturing a variety of processes associated with deep convection. We use stepwise selection to select predictors for ELR and ZAGA based on the AIC. Predictors and coefficients are selected in a cross-validation framework based one two-years of training data and the skill of the forecasts are assessed on one-year of test data. The inclusion of additional predictors results in more skilfull forecasts, as expected, particularly for higher precipitation thresholds and for forecasts using the QRF method. We also assess the value of using a time-lagged ensemble. Forecasts derived from ZAGA and QRF are generally more skilfull, as defined by the Brier Skill Score, than ELR and lower precipitation amounts are skillfully predicted.

    Grasping the present situation of coal utilization technology in the Philippines, the paper proposed a feasibility study of introduction of the environmentally friendly type coal utilization system which seems to be needed in the future. (1) Introduction of the environmentally friendly type coal utilization system in the electric power generation sector: there are only four full-scale running coal thermal power plants in the Philippines. In the future, several coal thermal plants are planned to be constructed by 2005, but for the new installation, it is desirable to adopt fluidized bed boilers with wide application to coal kinds. In case of 0.3-1.0 million MW class plants, it is planned to adopt high grade import coals, and it will be natural to fire pulverized coal. For the processing of flue gas, it is a must to install desulfurization facilities and smoke/soot removal devices. (2) Utilization/development of domestic low grade coals: at the mine-mouth generating plant, it is necessary to investigate the economically minable amount of coal, confirm productivity, survey coal quality, etc., and select boiler. As to coal briquetting technology, it is necessary to examine coal quality for tests and make a thorough study of what technology is most suitable. 50 figs., 78 tabs.

    The biological effects of acute particulate air pollution exposure in host innate immunity remain obscure and have relied largely on in vitro models. We hypothesized that single acute exposure to ambient or engineered particulate matter (PM) in the absence of other secondary stimuli would activate lung dendritic cells (DC) in vivo and provide information on the early immunological events of PM exposure and DC activation in a mouse model naïve to prior PM exposure. Activation of purified lung DC was studied following oropharyngeal instillation of ambient particulate matter (APM). We compared the effects of APM exposure with that of diesel-enriched PM (DEP), carbon black particles (CBP) and silver nanoparticles (AgP). We found that PM species induced variable cellular infiltration in the lungs and only APM exposure induced eosinophilic infiltration. Both APM and DEP activated pulmonary DC and promoted a Th2-type cytokine response from naïve CD4+ T cells ex vivo. Cultures of primary peribronchial lymph node cells from mice exposed to APM and DEP also displayed a Th2-type immune response ex vivo. We conclude that exposure of the lower airway to various PM species induces differential immunological responses and immunomodulation of DC subsets. Environmental APM and DEP activated DC in vivo and provoked a Th2 response ex vivo. By contrast, CBP and AgP induced altered lung tissue barrier integrity but failed to stimulate CD4+ T cells as effectively. Our work suggests that respirable pollutants activate the innate immune response with enhanced DC activation, pulmonary inflammation and Th2-immune responsiveness. PMID:21099199

    Cascaded exploitation of diversion-type small hydropower (SHP) offers a source of new energy as well as socioeconomic benefits; however, it inevitably causes environmental disturbance and damage. Previous studies on the cumulative effect of cascaded diversion SHP rarely discussed using quantitative analysis method. In this paper, the ecological footprint analysis approach is proposed to assess the positive and negative impacts of cascaded diversion SHP on environment of a small-scale river in Southwest China. Positive impact is defined as ecological supply footprint (ESF), which refers to vegetation protection by replacing firewood with SHP. Negative impact is defined as ecological loss footprint (ELF), which includes fish and net primary productivity loss, vegetation destruction and soil erosion. With the raising in the number (n>4) of diversion SHP stations, the difference between ELF and ESF increases remarkably, suggesting that the adverse impacts of cascaded diversion SHP accumulate in the study area. Compared with vegetation destruction and soil erosion, the cumulative loss of fish and net productivity is the most important aspect of the adverse impacts which needs more attentions.

    Abortive infection is an anti-phage mechanism employed by a bacterium to initiate its own death upon phage infection. This reduces, or eliminates, production of viral progeny and protects clonal siblings in the bacterial population by an act akin to an "altruistic suicide." Abortive infection can be mediated by a Type III toxin-antitoxin system called ToxIN Pa consisting of an endoribonuclease toxin and RNA antitoxin. ToxIN Pa is a heterohexameric quaternary complex in which pseudoknotted RNA inhibits the toxicity of the toxin until infection by certain phages causes destabilization of ToxIN Pa , leading to bacteriostasis and, eventually, lethality. However, it is still unknown why only certain phages are able to activate ToxIN Pa . To try to address this issue we first introduced ToxIN Pa into the Gram-negative enterobacterium, Serratia sp. ATCC 39006 ( S 39006) and then isolated new environmental S 39006 phages that were scored for activation of ToxIN Pa and abortive infection capacity. We isolated three T4-like phages from a sewage treatment outflow point into the River Cam, each phage being isolated at least a year apart. These phages were susceptible to ToxIN Pa -mediated abortive infection but produced spontaneous "escape" mutants that were insensitive to ToxIN Pa . Analysis of these resistant mutants revealed three different routes of escaping ToxIN Pa , namely by mutating asiA (the product of which is a phage transcriptional co-activator); by mutating a conserved, yet functionally unknown, orf84 ; or by deleting a 6.5-10 kb region of the phage genome. Analysis of these evolved escape mutants may help uncover the nature of the corresponding phage product(s) involved in activation of ToxIN Pa .

    To examine the associations of perceived interparental relationship, family harmony and family happiness with smoking intention in never-smoking Chinese children and adolescents in Hong Kong. Cross-sectional surveys of 15 753 primary (grades 4-6) and 38 398 secondary (grades 7-12) never-smoking students from 71 to 75 randomly selected primary and secondary schools in Hong Kong, 2012-2013. Outcome variable was smoking intention which denoted any affirmative response to smoke within the coming year or when a cigarette was offered by a good friend. Exposure variables were perceived interparental relationship and family harmony each measured on a five-point scale from 'very good' to 'very bad' and perceived family happiness on a four-point scale from 'very happy' to 'not happy at all'. Potential confounders included age, sex, family structure, perceived family affluence, parental smoking and sibling smoking. In primary students, the adjusted ORs (AORs) (95% CI) of smoking intention generally increased with more negative perception of the family relationship: up to 3.67 (1.91 to 7.05) for interparental relationship, 7.71 (4.38 to 13.6) for family harmony and 5.40 (3.41 to 8.55) for family happiness. For secondary students, the corresponding AORs (95% CI) were 2.15 (1.64 to 2.82) for interparental relationship, 2.98 (2.31 to 3.84) for family harmony and 2.61 (1.80 to 3.79) for family happiness. All p for trend happiness were associated with higher odds of smoking intention with dose-response relationships in never-smoking Chinese children and adolescents in Hong Kong. Children's perception of their family relationship may be an important intervening point for preventing youth from initiating smoking. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 tabs.

In 47 of the 57 the NIPT result was confirmed by genetic testing of material obtained by amniocentesis or chorionic biopsy, and no false-positive results were recorded. The false-negative rate as determined on more than 2000 women that had delivered at the time of reporting was low, and so far only 2 false-negative results were reported (one trisomy 18 and one trisomy 21). The failure rate where no NIPT result could be obtained after repeated sampling was 0.90%. In this large clinical series, NIPT using the Harmony test proves to be a very reliable prenatal test to detect fetal trisomies 21, 18 and 13 in maternal blood in Belgium and the Netherlands.

  2. Simultaneous determination of aquifer parameters and zone structures with fuzzy c-means clustering and meta-heuristic harmony search algorithm

    2007-11-01

    This study proposes an inverse solution algorithm through which both the aquifer parameters and the zone structure of these parameters can be determined based on a given set of observations on piezometric heads. In the zone structure identification problem fuzzy c-means ( FCM) clustering method is used. The association of the zone structure with the transmissivity distribution is accomplished through an optimization model. The meta-heuristic harmony search ( HS) algorithm, which is conceptualized using the musical process of searching for a perfect state of harmony, is used as an optimization technique. The optimum parameter zone structure is identified based on three criteria which are the residual error, parameter uncertainty, and structure discrimination. A numerical example given in the literature is solved to demonstrate the performance of the proposed algorithm. Also, a sensitivity analysis is performed to test the performance of the HS algorithm for different sets of solution parameters. Results indicate that the proposed solution algorithm is an effective way in the simultaneous identification of aquifer parameters and their corresponding zone structures.

    A redundancy allocation is a famous problem in reliability sciences. A lot of researcher investigated about this problem, but a few of them focus on heterogeneous 1-out-of-N: G cold-standby redundancy in each subsystem. This paper considers a redundancy allocation problem (RAP) and standby element sequencing problem (SESP) for 1-out-of-N: G heterogeneous cold-standby system, simultaneously. Moreover, here, maximizing reliability of cold-standby allocation and minimizing cost of buying and time-independent elements are considered as two conflict objectives. This problem is NP-Hard and consequently, devizing a metaheuristic to solve this problem, especially for large-sized instances, is highly desirable. In this paper, we propose a multi-objective harmony search. Based on Taguchi experimental design, we, also, present a new parameters tuning method to improve the proposed algorithm. - Graphical abstract: Example of solution encoding. - Highlights: • This paper considers a redundancy allocation and standby element sequencing problem. • To solve this problem, a multi-objective harmony search algorithm is proposed. • Dynamic parameters tuning method is applied to improved the algorithm. • With this method, sensitivity of the algorithm to initial parameters is reduced.

    It can be hard for individuals to manage multiple group identities within their self-concept (e.g., being a Christian and a woman). We examine how the inter-identity fit between potentially conflicting identities can become more harmonious through a self-defining group philosophy for life. Specifically, we test the hypothesis that holistic group identities (based in group philosophies for life that prescribe the behavior of their members in any situation, such as religion) become more strongly related to other identities in the self-concept (e.g., gender) when they are strongly self-defining (i.e., devotedly applied to daily life). In three studies we investigated the inter-identity fit between individuals’ (highly holistic) religious identity and (less holistic) gender identity. Results provided converging support for our hypothesis across diverging methods (explicit questionnaires, more implicit associations, and a novel network analysis of group traits). We discuss the importance of understanding how some (i.e., holistic and self-defining) group identities may harmonize otherwise less harmonious group identities within one’s self-concept.

    Full Text Available Multi-scale modeling of Arctic tundra vegetation requires characterization of the heterogeneous tundra landscape, which includes representation of distinct plant functional types (PFTs. We combined high-resolution multi-spectral remote sensing imagery from the WorldView-2 satellite with light detecting and ranging (LiDAR-derived digital elevation models (DEM to characterize the tundra landscape in and around the Barrow Environmental Observatory (BEO, a 3021-hectare research reserve located at the northern edge of the Alaskan Arctic Coastal Plain. Vegetation surveys were conducted during the growing season (June–August of 2012 from 48 1 m × 1 m plots in the study region for estimating the percent cover of PFTs (i.e., sedges, grasses, forbs, shrubs, lichens and mosses. Statistical relationships were developed between spectral and topographic remote sensing characteristics and PFT fractions at the vegetation plots from field surveys. These derived relationships were employed to statistically upscale PFT fractions for our study region of 586 hectares at 0.25-m resolution around the sampling areas within the BEO, which was bounded by the LiDAR footprint. We employed an unsupervised clustering for stratification of this polygonal tundra landscape and used the clusters for segregating the field data for our upscaling algorithm over our study region, which was an inverse distance weighted (IDW interpolation. We describe two versions of PFT distribution maps upscaled by IDW from WorldView-2 imagery and LiDAR: (1 a version computed from a single image in the middle of the growing season; and (2 a version computed from multiple images through the growing season. This approach allowed us to quantify the value of phenology for improving PFT distribution estimates. We also evaluated the representativeness of the field surveys by measuring the Euclidean distance between every pixel. This guided the ground-truthing campaign in late July of 2014 for

    An overview of environmental monitoring programs and research during development of a moderate temperature geothermal resource in the Raft River Valley is presented. One of the major objectives was to develop programs for environmental assessment and protection that could serve as an example for similar types of development. The monitoring studies were designed to establish baseline conditions (predevelopment) of the physical, biological, and human environment. Potential changes were assessed and adverse environmental impacts minimized. No major environmental impacts resulted from development of the Raft River Geothermal Research Facility. The results of the physical, biological, and human environment monitoring programs are summarized.

    Full Text Available From a reflection on market and consumption changes in contemporary China, this article discusses the Chinese diaspora's role in rediscovering "traditional" values, especially those related to notions of harmony, hard work and savings, based on the religious and philosophic Confucian heritage. If, on one hand, we observe today deep consumerism among the young generations living in China, on the other hand, the denial of conspicuous consumption appears as a distinctive feature among Chinese immigrants living in Ciudad del Este (Paraguay, where they work as importers and distributors of goods made in China. Due to these characteristics, I outline a comparison with the Calvinist ethic as analyzed by Max Weber, drawing approaches and differences between Protestantism and Confucianism regarding conspicuous spending, work ethic and wealth accumulation.

    In this paper, the authors present a new multistage framework for reliability-based Distribution Expansion Planning (DEP) in which expansion options are a reinforcement and/or installation of substations, feeders, and Distributed Generations (DGs). The proposed framework takes into account not only costs associated with investment, maintenance, and operation, but also expected customer interruption cost in the optimization as four problem objectives. At the same time, operational restrictions, Kirchhoff's laws, radial structure limitation, voltage limits, and capital expenditure budget restriction are considered as problem constraints. The proposed model is a non-convex optimization problem having a non-linear, mixed-integer nature. Hence, a hybrid Self-adaptive Global-based Harmony Search Algorithm (SGHSA) and Optimal Power Flow (OPF) were used and followed by a fuzzy satisfying method in order to obtain the final optimal solution. The SGHSA is a recently developed optimization algorithm which imitates the music improvisation process. In this process, the harmonists improvise their instrument pitches, searching for the perfect state of harmony. The planning methodology was demonstrated on the 27-node, 13.8-kV test system in order to demonstrate the feasibility and capability of the proposed model. Simulation results illustrated the sufficiency and profitableness of the newly developed framework, when compared with other methods. - Highlights: • A new multistage framework is presented for reliability-based DEP problem. • In this paper, DGs are considered as an expansion option to increase the flexibility of the proposed model. • In this paper, effective factors of DEP problem are incorporated as a multi-objective model. • In this paper, three new algorithms HSA, IHSA and SGHSA are proposed. • Results obtained by the proposed SGHSA algorithm are better than others

    Laboratory data generated in the past decade indicate a significant reduction in component fatigue life when reactor water environmental effects are experimentally simulated. However, these laboratory data have not been supported by nuclear power plant component operating experience. In recent comprehensive review of laboratory, component and structural test data performed through the EPRI Materials Reliability Program, flow rate was identified as a critical variable that was generally not considered in laboratory studies but applicable in plant operating environments. Available data for carbon/low-alloy steel piping components suggest that high flow is beneficial regarding the effects of a reactor water environment. Similar information is lacking for stainless steel piping materials. This report documents progress made to date in an extensive testing program underway to evaluate the effects of flow rate on the corrosion fatigue of 304L stainless steel under simulated PWR primary water environmental conditions.

    Full Text Available We propose to conceive an environmental strategy intended to integrate harmoniously Gorj energy industry with principles of sustainable development. The sustainable development complies trinomial: ecological-economic-social. In our view, sustainable development, requires clean water and unpolluted air, land consolidated rejuvenated forests, biodiversity and protected nature reserves, churches and monasteries secular admired by visitors, welcoming places entered in the natural and cultural harmony. It is also necessary to reduce the pressure generated by socio-economic factors on the environment and the principles of sustainable development. The quality of life in urban and rural areas show extreme differences compared to European standards. For efficiency, we addressed the modeling method by designing a model valid for all thermoelectric power plants based on fossil fuels, allowing simultaneously, so adding value and environmental protection. The general objective that we propose for the environment, natural resources and patrimony, is related to the prevention of climate change by limiting the emission of toxic gases and their adverse effects on the environment The achievement of strategic objectives and implementation of proposals submitted, we consider that would have a double impact, on the one side, to protect the environment and the quality of life and, on the other side a positive influence on economic and social level.

    This survey was made to obtain the basic data for future spread and promotion of No.6 type (waste use type production facilities) and No.7 type (waste fuel production facilities) which were added to the objects having been subsidized since fiscal 1997 under `the environmental harmony type energy community project.` In the former, the kiln in the cement industry and the blast furnace in the steel industry can be extremely large places to receive waste plastic since the facilities are distributed in every area and the treatment capacity is large. However, the effective collection, transportation and sorting of large quantity of waste plastic, especially the problem of removal of vinyl chloride, is a big bottleneck. As to the use of waste plastic using gasification technology, there are no actual results on the commercial basis. That is, however, appropriate for treatment of the waste difficult in treatment, and can be expected of the usage in the chemical industry. In the latter, in the facilities using industrial waste raw materials as fuel, solidification and liquefaction are both operated on a commercial basis. In relation to the solidification and use as fuel of general waste, the treatment of combustion ash is preventing the expansion of use of waste in the industrial field because of a large quantity of chlorine included in the products. 92 refs., 54 figs., 35 tabs.

    The European Union Reference Laboratory (EURL) for Listeria monocytogenes (Lm) collaborates with a network of 35 National Reference Laboratories (NRLs) throughout Europe. Most of these NRLs are in charge of detecting and typing Lm strains from food, environment and animals, which are isolated nationally. The past few years EURL activities have enabled NRLs to reinforce typing capabilities according to standardised protocols. Consequently the need to exchange typing data within the NRL network has emerged. That is why the EURL has recently set up a EURL Lm Database (EURL Lm DB). Each NRL contributes data, which is then shared within the network. Data include strain-typing-results (PFGE and serotyping) and epidemiological information on the strains. This article describes (1) the EURL typing activities that led to the creation of the EURL Lm DB, (2) the different steps involved in developing the EURL Lm DB, and (3) the usefulness of this database for public health. The combined use of this database, with databases on human strains, is being integrated into the European surveillance system of Lm strains circulating throughout Europe. It should improve the detection of this pathogen and provide support for outbreak investigations. Copyright © 2014 Elsevier B.V. All rights reserved.

    2007-11-01

    Now that analysis of the organization of the human genome sequence is reaching completion, studies of the finely tuned chromatin epigenetic networks, DNA methylation and histone modifications, are required to determine how the same DNA sequence generates different cells, lineages and organs, i.e. the phenotype. Maternal nutrition, behaviour and metabolic disturbances as well as other environmental factors have been shown to have major effects on these epigenetic processes, potentially affecting the predisposition of offspring to obesity and related adult disorders. The March 2006 Stock Conference considered the latest evidence from studies in the field of obesity and other related areas that elucidate mechanisms by which the environment can modify gene expression and the resulting individual phenotype. Presentations included evaluation of the molecular basis of epigenetic memory and the nature of relevant sequence targets, windows of susceptibility, and maternal dietary and behavioural factors that determine epigenetic changes. Imprinted genes, age and tissue-related exposures, transgenerational and potential interventions were also discussed. In summary, it is clear that epigenetic alterations can no longer be ignored in evaluations of the causes of obesity and its associated disorders. There is a need for systematic large-scale epigenetic studies of obesity, employing appropriate strategies and techniques and appropriately chosen environmental factors in critical spatio-temporal windows.

    Objective: To determine incidence and trends related to the appearance of bladder, kidney, non melanoma skin (except head and neck),lung, liver and colon cancer in the State of Cesar and in the entirety of its municipalities from January 1, 1998-December 31, 2006. Methods: A descriptive, transverse epidemiologic study carried out in the municipalities of the State of Cesar where environmental exposure to obsolete or near obsolete pesticides had occurred. Census of secondary information sources was conducted at main geographical points where state residents sought medical care. Active data collection (at the source) was employed in accordance with Population Cancer Registry. Results: In the State of Cesar, between 1998-2006, average annual percentage and statistically significant changes occurred in the incidence of lung, colon, and rectal cancers for both sexes, and of non melanoma skin cancer for men. The municipalities of Agustin Codazzi and El Copey revealed age standard rates (ASR) above the state average for liver cancer in both sexes, and for bladder cancer in women. Gender related multiple ASR for the municipalities of Valledupar, Aguachica, Pailitas and La Paz stood out with respectively higher ASR than that for the entire State of Cesar. Conclusions: It is possible that there is a statistical and geospatial association between the incidence of the following cancers and the environmental exposure to PLADES: (a) bladder cancer in women, in Agustin Codazzi and El Copey; (b) bladder cancer in men, only in El Copey, and (c) non melanoma skin cancer in men, only in Agustin Codazzi.

    The adoption of US-type environmental impact statements is considered to be approaching. Environmental impact statements are defined as comprehensive analyses of the future effects of measures on environmental conditions with the aim of avoiding ecological disadvantages. The recommendation ratified by the European Communities on June 27, 1985 requires the environmental impact statement to be implemented as a mandatory procedure. The implementation is difficult to realize. Particular problems consist in the alignment of the environmental impact statement with existing administrative procedures and in the operationable formulation of the aims and results of the statement. Paragraph 72 of the administrative procedures law (VwVfG) shows that planning procedures and environmental impact statement are to be treated as two parallel regulations. The structural order of environmental impact statements must therefore be integrated into the regulations of planning procedures. (orig./HP) [de

    Full Text Available Migraine can be triggered by many factors such as stress, sleep, fasting and environmental causes. There are few studies that evaluated migraine trigger factors in the adolescent population. Methods: A total of 100 participants from 10 to 19 years were subjected to a detailed headache questionnaire, with demographic and clinical data, and a headache diary including trigger factors during a two-month period was asked. Results: Fifty of the participants exhibited chronic migraine and the other 50 participants demonstrated episodic migraine. The most common group of trigger factors reported was the environmental one, mainly sun/clarity, followed by hot weather and the smell of perfume. Conclusions: Ninety-one percent of children and adolescents with migraine reported a trigger factor precipitating the migraine attack.Crises de migrânea podem ser desencadeadas por muitos fatores, como estresse, sono, jejum e causas ambientais.

    Despite the last decade considerable advances in the study of nitrate and nitrite pollution of soil, there are still some gaps in research related to neglecting or ignoring the role of soil in the food chain and its effects on upper trophic units. The article presents the results of a study on the impact of air and soil humidity and temperature, as well as soil type and utilization on the amount of nitrates and nitrites in the soil solution at the end of vegetation period. It was proved that statistically significant impact on the amounts of residual nitrate and nitrite ions was caused by the temperature and moisture of soil, its type, and the specific properties of the crops grown.

    Following the predictions of total energy calculations, a tetragonal SrMn 2 P 2 phase is proposed and successfully formed under high pressure. At ambient pressure, SrMn 2 P 2 adopts the primitive trigonal La 2 O 3 structure type (space group P3[combining macron]m1). However, the results of total energy calculations indicate that SrMn 2 P 2 should be more stable in the tetragonal ThCr 2 Si 2 structure type (space group I4/mmm) than in its known trigonal structure, thus motivating our synthetic experiments. Guided by these calculations, a new tetragonal polymorph of SrMn 2 P 2 was found under the relatively mild conditions of 5 GPa applied pressure at a temperature of 900 °C through the transformation of the ambient pressure trigonal form. The new polymorph has the body centered tetragonal ThCr 2 Si 2 structure type, as predicted. The electronic structure calculations indicate the likelihood of antiferromagnetic, semiconducting properties for the high pressure SrMn 2 P 2 phase.

    The background γ-ray intensity and chemical composition of soil was determined in the Naka terrace of Tokai-mura Village and Hitachinaka City, where many nuclear facilities are located. The aim of the sampling was to assess environmental radiation within the Naka terrace and the sites of nuclear facilities. The study was initiated following the JCO Criticality Accident on September 30th, 1999. γ-ray measurement and soil sampling were conducted at the nodes of a 500 m grid. The γ-ray intensity recorded at all sample points is less than the average radiation of Japanese granites and less than the typical radiation of humans as assessed by UNSCREA. The chemical characteristics of the soil are divided into 3 types. The distribution of both the soil types and background γ-ray intensity is controlled by geographical and geological factors. K 2 O and Rb concentrations within the soil show a good correlation with background γ-ray intensity. Our observations indicate that environmental radiation within the study area is derived principally from natural radioisotope radiation. (author)

    This article offers a reconstruction of the vegetation and climate of the south-western Siberian Baraba forest-steppe area during the last ca. 8000 years. The analysis of palynological data from the sediment core of Lake Bolshie Toroki using quantitative methods has made it possible to reconstruct changes of the dominant types of vegetation and mean July air temperatures. Coniferous forests grew in the vicinity of the lake, and mean July air temperatures were similar to present-day ones between 7.9 and 7.0 kyr BP. The warmest and driest climate occurred at 7.0-5.0 kyr BP. At that time, the region had open steppe landscapes; birch groves began to spread. A cooling trend is seen after 5.5 kyr BP, when forest-steppe began to emerge. Steppe communities started to dominate again after 1.5 kyr BP. Mean July air temperatures lower than now are reconstructed for the period of 1.9-1 kyr BP, and then the temperatures became similar to present-day ones. Comparing the archaeological data on the types of economy of the population which inhabited the Baraba forest-steppe with the data on changes in the natural environment revealed a connection between the gradual transition from hunting and fishing to livestock breeding and the development of forest-steppe landscapes with a decrease in the area covered by forests. The development of the forest-steppe as an ecotonic landscape starting around 5 kyr BP might have contributed to the coexistence of several archaeological cultures with different types of economy on the same territory.

  15. Role of environmental variables on the stress corrosion cracking of sensitized AISI type 304 stainless steel (SS304) in thiosulfate solutions

    2004-10-01

    The stress corrosion cracking (SCC) behavior of sensitized AISI type 304 stainless steel (SS304) has been studied in dilute thiosulfate solutions as a function of thiosulfate concentrations and applied potentials. The susceptibility to SCC was observed to increase with thiosulfate concentrations and applied potentials. The addition of boric acid produced the reverse effect. A critical potential was found to exist, below which no SCC took place. Potential fluctuations, as recorded in the tests under open circuit conditions, appeared to be correlated with crack initiation and propagation during SCC. Current fluctuations observed in the controlled potential tests also gave indications of crack nucleation; however, at higher applied potentials such fluctuations were absent. The formation and presence of martensite in the specimens seemed to have a minor role in the overall SCC process. The aggressiveness of the thiosulfate concentration was also an important factor in determining the degree of susceptibility to SCC. The results obtained in the slow strain rate tests under open circuit as well as under potential-controlled conditions suggested a film ruptureanodic dissolution type of mechanism operative during SCC of sensitized SS304 in thiosulfate solutions.

    The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

  18. HSTLBO: A hybrid algorithm based on Harmony Search and Teaching-Learning-Based Optimization for complex high-dimensional optimization problems.

    Directory of Open Access Journals (Sweden)

    Shouheng Tuo

    Full Text Available Harmony Search (HS and Teaching-Learning-Based Optimization (TLBO as new swarm intelligent optimization algorithms have received much attention in recent years. Both of them have shown outstanding performance for solving NP-Hard optimization problems. However, they also suffer dramatic performance degradation for some complex high-dimensional optimization problems. Through a lot of experiments, we find that the HS and TLBO have strong complementarity each other. The HS has strong global exploration power but low convergence speed. Reversely, the TLBO has much fast convergence speed but it is easily trapped into local search. In this work, we propose a hybrid search algorithm named HSTLBO that merges the two algorithms together for synergistically solving complex optimization problems using a self-adaptive selection strategy. In the HSTLBO, both HS and TLBO are modified with the aim of balancing the global exploration and exploitation abilities, where the HS aims mainly to explore the unknown regions and the TLBO aims to rapidly exploit high-precision solutions in the known regions. Our experimental results demonstrate better performance and faster speed than five state-of-the-art HS variants and show better exploration power than five good TLBO variants with similar run time, which illustrates that our method is promising in solving complex high-dimensional optimization problems. The experiment on portfolio optimization problems also demonstrate that the HSTLBO is effective in solving complex read-world application.

  19. Dynamism in a Semiconductor Industrial Machine Allocation Problem using a Hybrid of the Bio-inspired and Musical-Harmony Approach

    Science.gov (United States)

    Kalsom Yusof, Umi; Nor Akmal Khalid, Mohd

    2015-05-01

    Semiconductor industries need to constantly adjust to the rapid pace of change in the market. Most manufactured products usually have a very short life cycle. These scenarios imply the need to improve the efficiency of capacity planning, an important aspect of the machine allocation plan known for its complexity. Various studies have been performed to balance productivity and flexibility in the flexible manufacturing system (FMS). Many approaches have been developed by the researchers to determine the suitable balance between exploration (global improvement) and exploitation (local improvement). However, not much work has been focused on the domain of machine allocation problem that considers the effects of machine breakdowns. This paper develops a model to minimize the effect of machine breakdowns, thus increasing the productivity. The objectives are to minimize system unbalance and makespan as well as increase throughput while satisfying the technological constraints such as machine time availability. To examine the effectiveness of the proposed model, results for throughput, system unbalance and makespan on real industrial datasets were performed with applications of intelligence techniques, that is, a hybrid of genetic algorithm and harmony search. The result aims to obtain a feasible solution to the domain problem.

    The Myers-Briggs Type Indicator was administered to a sample of 61 monozygotic twins reared apart (MZA), 49 dizygotic twins reared apart (DZA), and 92 spouses, who participated in the Minnesota Study of Twins Reared Apart (MISTRA) from 1979 to 1995. Twins' scores on the continuous scales were subjected to behavior genetic model-fitting procedures. Extraversion-Introversion and Thinking-Feeling yielded heritabilities of about .60, consisting largely of nonadditive genetic variance. Sensing-Intuition and Judgment-Perception yielded heritabilities of about .40, consisting largely of additive genetic variance. Spouse correlations for three of the four scales were near zero and not statistically significant; one spouse correlation (Sensing-Intuition) was modestly positive and statistically significant.

    In order to meet the goal of environmental education, creating generation who are environmentally concerned and responsible, Ar Ridho Nature School Semarang (SAA), put the message of such education on their gardening subject. The subject has designed for grade 1 to 6 as the school commitment to build a civilization who are able to live in harmony with nature. The purpose of gardening is not only giving students environmental knowledge but also building environmental awareness and skill to preserve nature. Thus, this study aims at presenting environmental awareness among students of SAA and finding out whether there is a relationship between environmental knowledge and environmental awareness.

    RNA-seq-based SSU (small subunit) rRNA (ribosomal RNA) analysis has provided a better understanding of potentially active microbial community within environments. However, for RNA-seq library construction, high quantities of purified RNA are typically required. We propose a modified RNA-seq method for SSU rRNA-based microbial community analysis that depends on the direct ligation of a 5’ adaptor to RNA before reverse-transcription. The method requires only a low-input quantity of RNA (10–100 ng) and does not require a DNA removal step. The method was initially tested on three mock communities synthesized with enriched SSU rRNA of archaeal, bacterial and fungal isolates at different ratios, and was subsequently used for environmental samples of high or low biomass. For high-biomass salt-marsh sediments, enriched SSU rRNA and total nucleic acid-derived RNA-seq datasets revealed highly consistent community compositions for all of the SSU rRNA sequences, and as much as 46.4%-59.5% of 16S rRNA sequences were suitable for OTU (operational taxonomic unit)-based community and diversity analyses with complete coverage of V1-V2 regions. OTU-based community structures for the two datasets were also highly consistent with those determined by all of the 16S rRNA reads. For low-biomass samples, total nucleic acid-derived RNA-seq datasets were analyzed, and highly active bacterial taxa were also identified by the OTU-based method, notably including members of the previously underestimated genus Nitrospira and phylum Acidobacteria in tap water, members of the phylum Actinobacteria on a shower curtain, and members of the phylum Cyanobacteria on leaf surfaces. More than half of the bacterial 16S rRNA sequences covered the complete region of primer 8F, and non-coverage rates as high as 38.7% were obtained for phylum-unclassified sequences, providing many opportunities to identify novel bacterial taxa. This modified RNA-seq method will provide a better snapshot of diverse

    The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

    late minerals. The early fluids may have reacted primarily with Devonian and Lower Carboniferous carbonate aquifers deeper in the basin, whereas the later fluids appear to have had extensive contact with organic-rich rocks, probably the shallower Middle and Upper Carboniferous flysch associated with coal measures. High concentrations of toxic Tl and As occur in the readily oxidized marcasite and pyrite minerals deposited by the later fluids. In general, the geochemistry of both the early and late fluids may be explained by an evaporite related origin or by water-rock modification of a saline basinal brine. When compared to the composition of fluid inclusions in Mississippi Valley-type (MVT) ore minerals from the Ozark region of the United States, fluid inclusions in minerals from Silesian-Cracow are fundamentally different, containing more Ca2+, Mg2+, NH+4, Br-, Sr2+ and acetate in all mineral stages with significantly more K+ in later stage minerals. The differences in ore fluid chemistry between the two regions are consistent with the lithologic differences of the respective basins thought to be the source of the mineralizing brines.

    Full Text Available The present work addresses a decentralized, well tested three-area multi-unit power system for its automatic generation control (AGC after deregulation which is characterized by price-based market operation. To match with the actual deregulated environment, as prevailing in the real one, the market structure is kept generic enough enabling to capture all possibilities occurring in real-time day-to-day power environment. In accordance to the modifications, as done in the investigated three-area power system model, the concerned objective is to intensify the deregulated AGC operation followed by load disturbances. At the present platform, three different classes of case study results are postulated for the studied test system. The first two illustrate the behavior of unilateral and bilateral based power contract transactions while the third one considers the contract violation case as it exists in present time. The contractual agreement, instituted by DISCO participation matrix, is initialized to address the power transaction contracts. In this work, a novel quasi-oppositional harmony search (QOHS algorithm is explored and presented its significances in deregulated AGC operation. In the second phase of investigation, fast acting Sugeno fuzzy logic technique is explored for on-line, off-nominal operating conditions. For analysis purpose, both the qualitative and the quantitative aspects of the proposed QOHS are presented in reference to genetic algorithm (GA. Additionally, the sensitivity analysis is also performed to evaluate the performance of the proposed QOHS based controller. Simulation work reveals that the proposed QOHS may be, effectively, worked out to order to improve the deregulated AGC performance. It is also being observed that the proposed QOHS outperforms the GA in sense of deregulated AGC operation of power system.

    Full Text Available Following the military defeat of LTTE terrorism in May 2009, the relationship between ethnic and religious groups in Sri Lanka became seriously fragmented as a result of intensified anti-minority sentiments and violence. Consequently, the ethnic Muslims (Moors became the major target in this conflict. The major objective of this study is to critically evaluate the nature and the impact of the anti-Muslim sentiments expressed and violence committed by the extreme nationalist forces during the process of ethnic reconciliation in post-war Sri Lanka. The findings of the study reveal that, with the end of civil war, Muslims have become “another other” and also the target of ethno-religious hatred and violence from the vigilante right-wing ethno-nationalist forces that claim to be protecting the Sinhala-Buddhist nation, race, and culture in Sri Lanka. These acts are perpetrated as part of their tactics aimed to consolidate a strong Sinhala-Buddhist nation—and motivated by the state. Furthermore, the recourse deficit and lack of autonomy within the organizational hierarchy of the Buddhist clergy have motivated the nationalist monks to engage in politics and promote a radical anti-minority rhetoric. This study recommends institutional and procedural reforms to guide and monitor the activities of religious organizations, parties, and movements, together with the teaching of religious tolerance, as the preconditions for ethnic reconciliation and ethnic harmony in post-war Sri Lanka. This study has used only secondary data, which are analyzed in a descriptive and interpretive manner.

    Full Text Available Judith Shapiro's latest ambitious work picks up the story of modern China's checkered relationship with the environment at approximately the point where her previous study, Mao's War Against Nature (2001, left off. This latest book sets out to address questions of grave importance to China and to the world. The litany of challenges – poisonous water and toxic air, scarcity of water and other resources, deforestation, soil erosion, loss of biodiversity – seem nearly insurmountable, despite evidence of considerable attention from the Chinese government and from China's public, and despite the rocket-like rise of China's economic power and political influence in the world. Shapiro adds to this list the growing problems with lapses in environmental justice, both within China and passed on to its neighbours and to the countries with which it trades.1 Not only do growing environmental problems affect China's ability to achieve the government's stated goals of a 'harmonious society' with 'moderate prosperity for all,' but these problems, and the ways that China seeks to address them, are now widely recognized as having major impacts on the entire planet. Chinese demand has become a major factor in the pricing of the world's natural resources, while pollution from Chinese sources, particularly emissions of CO2 and other climate changing gasses, are having global consequences.
