This paper presents a predictive control scheme, based on the receding horizon optimal control (RHOC) approach with zero terminal constraint, to guarantee the closed-loop stability of linear $2\times 2$ hyperbolic systems with boundary control. The extension of this control scheme to networks of such hyperbolic systems is also considered. The boundary control problem is first reformulated in the abstract form for which the optimal control with terminal constraint was well studied. These results are then used in the RHOC scheme to give a complete proof of stability of the closed-loop system. For the implementation, the calculus of variations is used to derive the adjoint state which is then discretized and solved together with the state to obtain the optimal control. The analysis is applied to open-channel hydraulic systems in cases of single pool and multipools in cascade. Finally, simulations are carried out to illustrate the effectiveness of the here-proposed approach.


vessel endothelial cell proliferation than breast carcinomas with an infiltrative growth pattern. There was also an association with the presence of a fibrotic focus, which is considered to be a marker of hypoxiadriven angiogenesis. These results and the recent observations that some of the angiogenic growth factors (eg, vascular endothelial growth factor-A, the angiopoietins, fibroblast growth factor-2 and platelet-derived growth factor-BB) also promote lymphangiogenesis are in favor of a possible link between both processes. Our results do suggest the occurrence of lymphangiogenesis in breast cancer and underscore an obvious need for a general consensus on the methodology of lymphangiogenesis quantification to determine the clinical significance of lymphangiogenesis in breast cancer.


It has been previously observed that perfusion of the thyroid-parathyroid gland complex in the dog with high calcium blood results in liberation of a hypocalcemic factor, calcitonin. In sheep, the superior parathyroid gland is separated by 2–3 cm from the thyroid and has a distinct blood supply, so that it can be perfused independently. Perfusion of this gland with high calcium blood (10.8–12.8 mg/100 ml) in 6 sheep, 3 of which had been thyroidectomized immediately prior to perfusion, resulted in a prompt fall in systemic plasma calcium, the change in 30 min being -0.530 ±0.074 mg/100 ml. Subsequently, in 5 adult sheep and 5 lambs, the thyroid was first perfused with high calcium blood for 1 hr, and then the superior parathyroid. Perfusion of the thyroid had no significant effect on systemic plasma calcium, but perfusion of the superior parathyroid resulted in a significant fall at 10 min and a change of -0.706 ±0.088 mg/100 ml by 30 min. The drop 30 min following parathyroidectomy was small and not stati...


This article is based on a CIE Technical Report that describes an intercomparison of measurements of the (total) spectral radiance factor (SRF) of luminescent materials. Seven luminescent specimens were provided as painted panels: two were white containing fluorescent whitening agents and five were chromatic [green, yellow, orange (two), and red]. The SRFs were measured with direct specimen illumination by a source simulating CIE D65. The SRFs that would have been obtained under D65 illumination were calculated by a method selected from among those previously studied by the committee. Data sets from four laboratories (one supplying two sets) gave useful results. The mean CIELAB color difference from the mean of the five data sets was 2.6 units averaged over all data sets and specimens, with a range among specimens from 1.9 to 3.4 units and among data sets from 1.5 to 4.2 units. The mean color difference from the results of an arbitrary reference laboratory was 3.6 units averaged over all data sets and specimens, with a range among specimens from 3.0 to 4.2 units and a range among data sets from 2.1 to 5.3 units. Maximum values of the SRFs varied considerably among the data sets, from 11.4% to 33.6% among the samples. It was the CIE Technical Committee's feeling that these results are representative of the present state of the art for this measurement, despite the relatively poor performance seen.

The incidence of diabetes in Indonesia has been increasing year by year. Diets with a low glycemic index and high resistant starch foods can assist diabetics in controlling their blood glucose levels. Diabetics are known to have micro-nutrient deficiencies of chromium, magnesium and vitamin D that can be overcome by consuming parboiled rice fortified by use of a coating method. The fortification of parboiled rice (premix rice) can be achieved by coating with HPMC (hydroxypropyl methyl cellulose), MC (methyl cellulose), CMC (carboxyl methyl cellulose), gum arabic and rice starch. This research aimed to evaluate the levels of resistant starch, glycemic index and fortificants of premix rice coated with different concentrations and types of edible coating materials. This research used completely randomized design, with treatments to the concentrations and the types of edible coating (HPMC, CMC, MC, gum arabic and rice starch). The concentrations of edible coating were 0.15%, 0.2% and 0.25% for cellulose derivative coatings; 25%, 30%, 35% for gum arabic and 2%, 3.5% and 5% for rice starch. This research shows that fortified premix rice coated with various concentrations and types of edible coating materials is high in resistant starch and has a low glycemic index. The coating treatment affects the levels of magnesium and vitamin D, but does not affect the levels of chromium in parboiled rice. The premix rice with a low glycemic index and high nutrient content (chromium, magnesium and vitamin D) was premix rice coated by CMC 0.25% and HPMC 0.25% with glycemic indeces of 39.34 and 38.50, respectively.


Background: The inhalation of anesthetic vapors into the lungs is a function of both the respiration and inhalant property. Factors which influence the alveolar concentration of anesthetics include breathing activities, airway morphology, anesthetic diffusivity, and wall absorption rate. Administered anesthetic levels could be significantly different from the alveolar level due to wall absorption loss and gas mixing in the airway. Objective: To assess the transport and absorption of inhaled anesthetics in an anatomically accurate respiratory airway geometry. Specifically aims include understanding the transport of inhaled vapors, quantifying the pulmonary dosage of administered anesthetics, and identifying factors that influence airway absorption losses. Methods: The geometry consisted of a CT-based mouth-throat (MT) model and a tracheobronchial (TB) model which extends to G9 bronchioles and consists of 115 outlets. Vapor transport and absorption were simulated using the Chemical Species model coupled with a user-defined vapor-absorption module. Results: Unlike previously assumed developed flows after G6, features of developing flows are still apparent in the G9 bronchioles in this study. Large variations of bronchiolar vapor concentrations were observed among the five lobes. Under quiet breathing conditions, vapor concentrations at the G9 outlets are 15 - 30% of the inhaled concentration level due to gas mixing and wall absorption. The delivered dose to the pulmonary region varies from 48% to 96%, depending on the vapor diffusivity and solubility. Vapor depletion due to wall absorption is significant (52%) for highly soluble anesthetics and is inconsequential for low solubility ones. Conclusion: A computer model was developed that implemented a wall absorption module in a realistic mouth-lung model extending to G9. This model provides the basis for future quantitative studies of the relationship between administered anesthetics and induced anesthetic level.

Abstract The environmental licensing has generated uncertainties about its effectiveness; making it necessary to encourage mechanisms to improve the political-institutional setting. Thus, this study aimed at evaluating the legal and technical concordances of the environmental licensing processes of mining enterprises in the south of the state of Minas Gerais. Using checklists, thirteen licensing processes were analyzed, where the pre- and post-approval stages were assessed. It was observed that the environmental studies didn't correspond to the terms of reference and the expected quality, as well as the noncompliance of the proponents regarding the approval of the environmental management reports. Therefore, it was concluded that there is a lack of technical performance of the analysts of the competent environmental agency and, therefore, it is necessary to improve the technical evaluation system of environmental studies as a tool to improve EIA processes.

In light of emission reduction and weight saving in transport applications, Mg parts gain alot attention due to their good specific mechanical properties and their low mass. While casting is themain process for manufacturing Mg parts for automotive applications, forged parts show some majorbenefits like superior mechanical properties and absence of porosity. In this work a comparison ofclosed die forged parts made from different Mg-alloys has been carried out. The materials used in thewarm forging process were AZ31 and various Mg-Al-Zn-Ca-Y type (AZXW) alloys. Ca additions areknown to improve the oxidation behaviour and the formability of magnesium alloys, while yttrium isused to enhance the flammability resistance of forged parts. The forgeability, mechanical propertiesand microstructure are analyzed and compared in the present paper.

Lavage of open fractures is crucial and proven to reduce the risk of secondary infection. Irrigation leads to spillage of fluid, which soaks surgical drapes, increasing the chances of wound contamination. Gowns worn by the surgical and nursing staff get wet, increasing exposure of potentially contaminated body fluids from the patient. We report the use of a tray, at the Coventry and Warwickshire Hospital. The limb is placed on the tray, excess irrigant drains through the holes and collects in the underlying compartment and can be discarded via a sucker. In our experience, this reduces the spillage of excess irrigant. This tray was manufactured locally, at the hospital workshop, and has been in use for over 30 years (unfortunately not available commercially). We suggest this tray provides a useful adjunct to reducing spillage of lavage fluid.

An investigation is described into the application of quality function deployment (QFD) and case based reasoning (CBR) to software quality assessment. It is believed that the integration of CBR and QFD may be an effective means of supporting the development of quality software. The main aim in the research is to develop a CBR oriented software quality advisor to support the attainment of quality in software development, by reference to quality case histories using software modules from previous designs. A model linking CBR and QFD mechanisms is presented. Current work is centred on the development of a prototype system in the form of a shell incorporating an interface linking the user requirements, the QFD and CBR mechanisms, and supported by a dynamic library of case histories.


High-gain, self-amplified spontaneous emission free-electron lasers (SASE FEL{close_quote}s), with proposed operation in wavelengths extending down to x rays, require intense relativistic electron beams, which under certain conditions can generate large diamagnetic fields. The action of these fields has the potential to seriously degrade FEL performance. It is shown here by both analysis and simulation that the finite size of the electron beams diminishes this effect so that it is negligible for proposed SASE FEL{close_quote}s. thinsp {copyright} {ital 1998} {ital The American Physical Society}


With the social media boom in today's world, we see people constantly uploading photos of themselves along with their friends and family on various social media platforms such as Facebook, Instagram, Twitter, Google+, etc. What if they want to see all the photos in a categorized form such as photos with a particular person. In this paper, we extend the concept of Multiview Face Detection using Convolution Neural Networks (CNN) used by Farfade et al. by providing a tagging system for the detected faces. For the face detection, we use Deep Dense Face Detector, which uses a single model based on deep convolutional neural networks. All the detected faces are recognized using Local Binary Patterns Histograms (LBPH) method. Precision, recall, and F-measure are the parameters used to measure the performance of the algorithm. An accuracy of 85% is achieved for tagging the faces which are successfully detected.

As a result of the increased number of papers presented on display topics at the 10th annual IS&T/SID Color Imaging Conference held in Scottsdale, Arizona, November 12–15, 2002, we decided that it would be of interest to the display community to publish a number of them in a special issue of the Journal of the SID. These papers are extended versions of papers published in the Color Imaging Conference Proceedings that have been reviewed by experts in the specific areas. The color performance of TFT-LCDs has undergone a dramatic improvement in recent years. Although the best TFT-LCD designs appear to have very good color characteristics, partly because of wide-viewing-angle liquid-crystal modes and enhanced monitor design, in general there is a need to understand and model the effects which lead to color additivity errors, hue shifts, and other undesirable characteristics. The first two papers in this issue, "Masking Model for Accurate Colorimetric Characterization of LCDs," by N. Tamura, N. Tsumura, and Y. Miyake (Chiba University, Japan), and "Controlling Color on Liquid-Crystal Displays," by Y. Kwak, C. Li, and L. MacDonald (University of Derby, U.K.), address these issues and propose new models for LCD characterization. The third paper "Colorimetric Characterization of LCD and DLP Projection Displays," by L. Seime and J. Y. Hardeberg" (SINTEF, Norway), investigates the possibility of characterizing LCD and DLP projectors (in two examples) with immediate application to color management. The fourth paper entitled "Adapting Softcopy Color Reproduction to Ambient Illumination," by J. Laine (VTT Technical Research Centre of Finland), discusses a display system which compensates for the perceptual effects of varying ambient illumination by means of color-appearance modeling. Psychophysical experiments confirm the improved color reproduction of this system. The fifth paper, "Color Conversion for Multi-Primary Display using Linear Interpolation on Equi-Luminance Plane Method," by H. Motomura (ANVR Center, Japan), discusses a color characterization method for a display system, which has more than three primaries. The six-primary DLPTM projector used as an example has a much larger gamut, which is very desirable, but enforces a new method converting device-dependent values into device-independent ones. The sixth paper "Optimal and Acceptable Color Ranges of Display Primaries for Mobile Applications," by E. Langendijk and I. Heynderickx (Philips, The Netherlands), proposes a method of testing in the 1976 CIE (u′ , v′) color space of the optimal, acceptable, or unacceptable ranges of display primaries for color reproduction of natural colors. The last paper of this special issue, Color Error from RGB-Stripe Pixel Structure," by M. Kanazawa, K. Hamada, and F. Okano (NHK Research Laboratories, Japan) quantifies the color error produced by a display with subpixel structure with a new modified s-CIELAB color metric, and also discusses convergence accuracy requirements using this new metric. We would like to thank the authors for their contributions and the reviewers for their significant time and effort that helped to ensure the high quality of the papers. We hope you will enjoy reading the papers and you will find them useful in your work.


According to the European Technology Platform for the Electricity Networks of the Future, a smart grid is an electricity network that can intelligently integrate the actions of all users connected to it - generators, consumers and those that do both - in order to efficiently deliver sustainable, economic and secure electricity supplies. The aim of this chapter is to give an overview of the recent and ongoing research activities that are focused on the smart grid domain. The international literature on this subject is particularly rich and growing. With this in mind, the motivation and key objective for the authors when preparing this chapter was an attempt to collate the distribution grid related research and innovation activities co-funded by the European Commission, in the context of the Horizon 2020 Work Programme 2014-2015 with activities co-funded by similar initiatives in the USA and Asian and Pacific countries. This material is accompanied by information about the recent past and the near future of smart grid research and innovation in Europe. On top of this mapping of facts and trends, this chapter presents the key objectives and functional characteristics of a set of information and communications technology (ICT) tools for the distribution grid that are being implemented in the context of SmarterEMC2, a collaborative project co-funded by the European Commission.


We modify the formulation of a labour supply model with unemployment, to allow for measurement errors in some of the indicators used to operationally identify the labour force state of each individual. The resulting model consists of the combination of two models: (I) the model of interest is a reduced form bivariate Probit model, aimed at explaining jointly the participation/non-participation decision and the employment/ unemployment outcome; (II) to this model, we superimpose a fairly general and flexible measurement model, specifying how discrete indicators - obtained from responses to a relevant set of questionnaire items - measure the labour force states. We establish conditions for model identification, and present a sensible iterative strategy for obtaining ML estimates. Evidence from a sample of married women in the Italian Labour Force Survey corroborates the intuitively plausible notion that parameter estimates are highly sensitive to alternative ways of defining unemployment, and documents the advantages of the proposed model.


Introduction: To face the topic of death as a natural consequence of life is not easy for many persons, and circumstances become more complex when suicide is brought into the picture. Objetive: this brief communication presents abuild of a questionnaire about suicidal attempt called "psychological biopsy". Methods: In the worldwide literature there are no consistent definition of the term "psychological biopsy" according to the search carried out in several databases (PubMed, SciELO, Bireme, PsycInfo, Web of Science, Google Scholar, Embase, SCOPUS, LILACS or BVS Psicologia). Results: questionnaire constructed proposes to investigate suicidal intention, that is, to carry out a psychological biopsy. Conclusion: The psychological biopsy was desinged to produce a diagnosis of attempted suicide in order to complement information needed to qualify the emotional disturbances of the person.


FEINSTEIN: Mr. Keaton, is it true that Harry Houdini first named you Buster?1 KEATON: Yeah, that's right. The show I was born with was a one night stand in Pickway, Kansas, in 1895, the Keaton and Houdini medicine show company. That's Harry Houdini, the handcuff king. My father was a grotesque comedian and my mother was the ingenue soubrette, a singer and dancer in the show. F: How come Houdini called you Buster? K: I fell down a flight of stairs when I was around six months old. They picked me up... no bruises, didn't seem to hurt myself and Houdini said, "That was a Buster." And the old man says, "That's a good name; we'll call him that." F: How did you write yourself into your parents' act, and become the Three Keatons?


The necessity of an exact determination of their parameters and characteristics appear in the connection with the extension of the sphere of application of solar photovoltaic modules in some cases. It is reasonable to use the method of computer modeling for the analysis of characteristics of specific solar modules at different levels of illumination and values of temperature. In the article there was presented the order of working out of a simulation model of photovoltaic modules in the medium Matlab/Simulink. The simulation model is based on the basis of pentaparametric analytical model of the volt-ampere characteristics of a solar cell. The worked out model allows to research the volt-ampere and volt-watt characteristics of solar modules in dependence on levels of intensity of solar radiation, temperature, values of short-circuit current, tension of single step, internal resistances of solar elements and a diode parameter as well. The discrepancy of data of results of modeling with technical characteristics does not exceed 7%

The myxinoid cyclostomes, of which the hagfish Myxine glutinosa L. is one of the best known examples, are of unique biological interest as representatives of a group of jawless vertebrates which probably had their origin in the pteraspidomorph ostracoderms of the Ordovician era (Nybelin, 1973). They have been much studied by comparative anatomists and physiologists but somewhat neglected by ecologists. There is, for instance, very little critical information on their normal feeding biology. Perhaps one reason for this is that, although hagfish may be extremely abundant locally (their principal habitat requirements are stable, soft muddy sediments and a salinity in excess of 31 %, (Gustafson, 1935)), they tend to be missed by most exploratory fishing and biological sampling programmes. This is because benthic sampling techniques are often ill-adapted for the capture of large active organisms capable of swimming and burrowing and because, unless blocked by the catch, the cod-end mesh sizes of the trawls used by most British commercial fishermen would easily permit the escape of even the largest hagfish. However, the research otter trawls used by the Department of Agriculture and Fisheries for Scotland (D.A.F.S.) for surveying the North Sea stocks of the deep water pink shrimp, Pandalus borealis Krøyer, are fitted with cod-end covers of small mesh, and it is found that the catches frequently include small numbers of hagfish, presumably caught while swimming close to the bottom, or possibly when buried in the surface of the sediments. The present study is largely based on the examination of hagfish collected during the D.A.F.S. Pandalus surveys of 1975 and 1976. The remaining material was kindly provided by Dr J. B. Buchanan of the Dove Marine Laboratory at Cullercoats, Northumberland.


Immunological memory has been induced in vitro against testicular autoantigens by priming normal rat T lymphocytes against autologous testis cells, and by permitting the isolated blast cells to revert back to small secondary lymphocytes (secondary EAO cells) in the absence of the priming antigen. The secondary EAO cells vigorously respond in a secondary response when reconfronted with syngeneic testis or lymphoid cells. Their responsiveness to nonself stimulator cells is, however, reduced. Secondary cells derived from concanavalin A-stimulated blasts, do not show that pattern of specificity. The specificity of the secondary EAO cells is definite, and cannot be affected by further culture on allogeneic fibroblasts, which are antigenic for unprimed T lymphocytes. At least part of the autoantigens are determined by the major histocompatibility gene complex (MHC). Factors provided by the culture system do not appear to determine the specificity of this reaction. Only minor cell populations can restimulate secondary EAO cells. One of these populations is presumably phage-like cells within the lymphoid populations can elicit a secondary EAO response. Thus, the autoantigens relevant in the secondary EAO response are either MHC antigens restricted to these testicular and lymphoid subpopulations, or MHC antigens recognized in conjunction with organ-specific non-MHC determinants.


Tests were performed to evaluate the effects of cure on the mechanical properties of composite laminates. The longitudinal and transverse tensile and compressive moduli and strengths and the longitudinal shear moduli and strengths of Fiberite T300/976 laminates were measured, with laminates cured to different degrees of cure ranging from 0.6 to 0.96. The laminate moduli and strengths were also calculated from the known values of the resin and fiber properties using the rule of mixture, Tsai-Hahn, Chamis, and Halpin-Tsai formu las. Comparisons were made between the measured and calculated laminate properties and the applicabilities of these formulas were assessed.

The state of a rigid disk at elastic waves diffraction on it and the possibility of its oscillation suppression using a multi-mass damper was studied in the paper. The operation of a three-mass dynamic oscillation suppression was considered and its application was compared with the operation of a two-mass damper. The effectiveness of the use of multi-mass dampers was estimated by the relative amplitude of disk oscillations and by the width of the frequency zone. It was stated that to suppress disk oscillations in a state of low instability of external impact frequency, the use of single- or two-mass dampers was sufficient. To reduce the disk displacements at unstable frequency of external impact (to cover a wider frequency zone), it is necessary to use a three-mass damper; the width of the damper effective operation significantly increases (about 4-5 times) compared to the operation of a two-mass damper.


The study on changes of soil fertilities was conducted in Michelia macclurei stands with different slope positions in 2004 and 2007.Compared with those in 2004,no significant changes in the soil density,capillary porosity,non-capillary porosity,total porosity and capillary moisture were observed in the upper-slope,middle-slope and lower-slope,whereas the natural water significantly increased in 2007.The pH value of the three positions decreased slightly,the contents of soil organic matter,total N and total K significantly increased,whereas total P content decreased in the three positions.The contents of soil hydrolyzable N and available P in the three positions and available K of the middle-slope and lower-slope significantly increased,and K of the upper-slope increased slightly.Soil physical properties changed with a non-regular pattern.The pH value and available P content of the three slopes were close to each other,the contents of soil organic matter,total N and total P were lower-slopemiddle-slopeupper-slope in 2004 and 2007.The content of soil hydrolyzable N of middle-slope and lower-slope was greater than that of upper-slope,and available K content of the upper-slope,middle-slope was smaller than that of the lower-slope in 2004,whereas it was lower-slopemiddle-slopeupper-slope in 2007.


This paper presents hybrid classification method to improve the performance of satellite images classification by combining Bayesian maximum likelihood classifier, ISODATA clustering and fuzzy C-Means algorithm. In this paper, the training data of each class were generated by separating the spectral signature using ISODATA clustering. We can classify according to pixel`s membership grade followed by cluster center of fuzzy C-Means algorithm as the mean value of training data for each class. Bayesian maximum likelihood classifier is performed with prior probability by result of fuzzy C-Means classification. The results shows that proposed method could improve performance of classification method and also perform classification with no concern about spectral signature of the training data. The proposed method Is applied to a Landsat TM satellite image for the verifying test.


Pediatric liver transplantation has evolved over the last few decades from an experimental therapy to standard of care in end stage liver disease. Apart from surgical expertise, the success of liver transplantation largely depends on perioperative care of the patient. Intensive care management plays a key role in supporting the pre-operative sick patient through the surgery and till the new liver graft starts to function and there is resolution of pre-operative morbidities. Pediatric patients are more challenging than the adult counterparts and demand minute attention to fluid volume status, hemodynamics and various organ-specific and graft specific issues. This review describes the various principles and challenges in the post-operative intensive care management of pediatric patients undergoing liver transplantation.


Objective To evaluate the dynamic effect of Huanglian Jiedu Tang (HLJDT) on Nimodipine disposition in rat brain. Methods In vivo, Nimodipine in plasma and brain tissue was measured in rats treated with Nimodipine alone or Nimodipine co-administered with HLJDT. In vitro, primary cultured brain microvessel endothelial cells (rBMEC) model was used to study the effect of serum obtained from HLJDT-treated rats, baicalin and berberine on the transport of Nimodipine across blood-brain barrier. Results In vivo, Cmax and AUC of Nimodipine were much higher than those in Nimodipine alone group when concomitantly ig adminstered HLJDT and the concentration of Nimodipine in braine tissue also increased in HLJDT-treated rats. In vitro, the serum of HLJDT-treated rats increasd the uptake of Nimodipine in rBMEC, so did baicalin (5 μg/mL) and berberine (10 ng/mL). But berberine (10 ng/mL) showed no effect on the uptake of Nimodipine. Conclusion The experimental findings indicate that HLJDT pretreatment might alter the pharmacokinetic behavior of Nimodipine both in plasma and brain tissue. The change of pharmacokinetic behavior of Nimodipine in brain tissue might partly result from the effect of baicalin in HLJDT.

first to offer an account of music's ubiquity in film, in spite of its seemingly awkward relationship to cinema, and the second to consider Rota's approaches to dealing with this apparent awkwardness. In following these objectives, Dyer prises out some of the many complications and contradictions that bedevil the alliance of music and film. Krin Gabbard also homes in on a specific individual – in this case Miles Davis – in a chapter that broaches the issue of music's role in the production and enforcement of racial values. Meanwhile, Rick Altman's thorough consideration of the processes surrounding music in early film and its latter-day conceptualization ('Early Film Themes: Roxy, Adorno, and the Problem of Cultural Capital') forces new ways of reading its subject matter, suggesting that the thematic, and in particular leitmotivic, approaches to film music analysis '[do] not stand the test of historical research' (222). Focusing on the music of early cinema seems timely, sitting alongside a growing critical interest in Nickelodeon cinema in general – a welcome development. The rich variety of scholarship offered in Beyond the Soundtrack and the volume's recognition, at long last, of the necessary plurality of critical approaches to the subject, make this work stand out as an important contribution to the field. Diverse in scope and context but with a strongly focused set of argumentative frameworks, this is an excellent collection, accessible yet critically uncompromising. It is to be highly recommended.


A fullerene is a 3-valent plane graphs whose faces are pentagons and hexagons. A fullerene is said to be IHR if its hexagons are adjacent, i.e. are adjacent only to pentagons. A space fullerene is a 4-valent tiling of the space by IHR fullerenes. Space fullerenes are interesting in crystallography and in Discrete geometry. There are exactly 4 IHR fullerenes of symmetry Ih, D6d, Td and D3h. We enumerates the space fullerenes with a small fundamental domain under their translation groups. The technique is decomposed into two steps: The use of Delaney symbols, i.e. flag systems, as the basic model for storing combinatorial informations and the use of the softwares 3dt and Systre by Olaf Delgado for transforming combinatorial description into topological and metric ones. The design of programs for enumerating space fullerenes, using all the tricks in the books of combinatorial enumeration in order to achive the highest speed possible.


At Lawrence Livermore National Laboratory (LLNL) the authors have been developing an open architecture machine tool controller. This work has been patterned after the General Motors (GM) led Open Modular Architecture Controller (OMAC) work, where they have been involved since its inception. The OMAC work has centered on creating sets of implementation neutral application programming interfaces (APIs) for machine control software components. In the work at LLNL, they were among the early adopters of the Java programming language. As an application programming language, it is particularly well suited for component software development. The language contains many features, which along with a well-defined implementation API (such as the OMAC APIs) allows third party binary files to be integrated into a working system. Because of its interpreted nature, Java allows rapid integration testing of components. However, for real-time systems development, the Java programming language presents many drawbacks. For instance, lack of well defined scheduling semantics and threading behavior can present many unwanted challenges. Also, the interpreted nature of the standard Java Virtual Machine (JVM) presents an immediate performance hit. Various real-time Java vendors are currently addressing some of these drawbacks. The various pluses and minuses of using the Java programming language and environment, with regard to a component-based controller, will be outlined.


Higher demand for broader and possible growth of the problem of state instability. Nothing more than a problem triggers social conflict on a small scale to a large scale. This study aims to identify and study various reasons in Indonesia and also formulate conceptions to increase the responsibility of communities in remote areas. The qualitative method in this study was carried out descriptively based on literature studies. The approach used in this study is integral to the national paradigm and applicable regulations. The results of the study show that the concepts that are following the conditions of the community, increase competitiveness among the environment that can be accessed by the government and facilitate people to manage the natural resources of the region, conduct and implement site-specific management and develop economic management to produce superior products.


THE decline in the death rate from tubercuculosis, from 160 per 100,000 in 1900 to 36 per 100,000 in 1936, is very encouraging. At the same time it is disquieting to know that this disease is still the leading cause of death between the ages of 15 and 45. It also is discouraging that "in the last twenty years little increase has occurred in the proportion of 'early cases' admitted to sanatoria."' Our present method of waiting until people come with complaints before examining or testing makes progress in the early detection of the disease very slow indeed. Only


1H NMR was used to study the motion of monomer units in a layer of poly(ethylene oxide) chains grafted on silica. First, the dependence of the relaxation times on the grafting ratios is discussed qualitatively from a phenomenological point of view. Next, the NMR line narrowing effect by high‐speed rotation is observed in the same samples with different grafting ratios. The magic angle spinning technique permits determination of two correlation times for each grafting ratio: τc characteristic of an environment with a fast motion and τl characteristic of an environment with a slow motion. In addition, the dynamics of these grafted chains are investigated by deuterium NMR (2H NMR), which is sensitive to the anisotropy of molecular motion. The evolution has been studied for two extreme grafting ratios and each time as a function of temperature. The anisotropy is more marked at low temperatures and for a low grafting ratio. The results are consistent with the 1H NMR relaxation times measured as a function of temperature. Copyright © 2007 John Wiley & Sons, Ltd.


In this paper, we studied the method of path distribution in order to increase reliability of the network by reducing path congestion, solving the problems of increasing blocking statistics, and increasing the utilization of network resource. A scheme of efficient path calculation which can reduce the traffic congestion in an arbitrary link is proposed by path calculation equations considering link occupation rates. A rapid method of establishing a connection which can efficiently cope with accidental connection failure are studied.


Abstract The article analyzes the anti-Islamic polemical discourse of Nicetas of Byzantium (9th/10th c.), one of the most important Byzantine apologists and polemicists flourishing in the intellectual-theological context of Patriarch Photios in Constantinople. This paper crystallizes the main topics of discussion in Nicetas' Refutation of the Qur'an (Vat. gr. 681) and presents his argumentation against Islam.To structure and evaluate the wayNicetas perceives Islam, I have developed a methodology of four thematic categories (Theology, Ethics, History, Physiology) with correspondent polemical subcategories. This research approach may also serve as a paradigm enhancing further studies on other sources related to Christian-Muslim interfaith dialogue.


A discussion of the methodology of racial intelligence testing is both pertinent and necessary. Three problems are involved: measurement of (I) the racial admixture factor; (2) the social status factor; (3) the linguistic disability factor. The methodology of each of these phases of the problem is discussed.


The design of sensitive, selective and reproducible biosensors with enzyme immobilisation for analytical application is reported. The study is aimed to develop a versatile and accurate analytical tool to be applicable for the determination of target analytes in real samples. The biosensor device is developed with employ immobilised enzyme as catalyic agent to convert target analytes to product that can be monitored electrochemically. Electrochemical biosensors, both in amperometric and potentiometric detection system have been prepared for different types of analytes. The strategy to immobilise ezyme in a matrix polymer is explained. Analytical performances of the the biosensors have been evaluated based on their detection sensitivity, linearity detection range, limit detection, selectivity, and stability. The enzyme electrode is prepared by immobilization of enzyme throughout polytyramine membrane film and attached tightly onto the surface of electrode. The working electrode was made via electropolymerization of monomer tyramine on an electrode surface from a mixed phosphate buffer/methanol solution containing enzyme at pH 6.0 followed by covalent attachment using EDC/NHS crosslinking agents. The precise control over the charge passed during deposition of the polytyramine polymer allows concomitant control over the thickness of the deposited enzyme layers onto the surface of the electrode. The reproducibility of the biosensors achieved is certainly due to the control of the thickness of the enzyme layer being limited by the resistance of the polytyramine film, and to the enzyme immobilization procedure on to the surface of the electrode. The biosensor showed good stability and to be applicable to determine analytes in real samples. Amperometric biosensor has been developed for the determination of various types of analytes such as glucose, sulfite, and uric acid. Potentiometric biosensor has also been developed with the same procedures for determination of analytes such as malic acid, cholesterol, and urea. The biosensor showed good stability and applicable to determine analyte in real samples.


A large unilocular multilobate bronchogenic cyst was found in the right superior mediastinum of a 93‐year‐old female anatomic cadaver. By reason of its location, shape, and serous membrane (pleural) coverings, it appeared to have been formed from a sequestered azygos lobe which slowly acquired alternate sources of vascu‐larization through adhesion to pericardial vessels and the arch of the azygos vein. It is postulated here that the relatively rudimentary organization of this cyst did not reflect a primitive stage of origin but was indicative of a plasticity in developing lung tissue that permitted a regression from a more advanced stage of morphogenesis when subjected to spatial restrictions; a process well demonstrated in a cited animal model. Thus, this case may illustrate that mediastinal bronchogenic cysts are not necessarily derivatives of the very early foregut components as previously proposed.


Surakarta has five subdistrict. Subdistrict with the highest density is Serengan and subdistrict with the lowest density is Jebres. In Serengan, Danukusuman is the crowded, whereas in Jebres, Mojosongo is the lowest density. Density differences problem can result in differences in the activity of the people who live.

So, this study done to know the characteristic comparison of high and low density settlements infrastructure provision pattern in Danukusuman and Mojosongo. To gain it, carried out was used a comparative analysis of settlement characteristics both in terms of physical, economic and socio-cultural. further analysis is to compare the characteristics of the infrastructure available with the applicable standards (SNI). then, final analysis is to determine and compare the pattern of provision of infrastructure and settlements in Danukusuman and Mojosongo . the results of the analysis is known that that there was no significant difference between high dense settlements (Danukusuman) and low dense settlements (Mojosongo) both from the aspect of the character of the location, infrastructure preparation and provision pattern. Only difference is quite prominent at the level of the economy and the provision of communal wastewater infrastructure that influenced by the density of settlement, while the difference in the provision of clean water is more influenced by the character of the location / the physical settlement . Keywords: high and low density, pattern of provision of infrastructure settlement infrastructure,


The effective functioning of data-intensive applications usually requires that the dataset should be of high quality. The quality depends on the task they will be used for. However, it is possible to identify task-independent data quality dimensions which are solely related to data themselves and can be extracted with the help of rule mining/pattern mining. In order to assess and improve data quality, we propose an ontological approach to report data quality violated triples. Our goal is to provide data stakeholders with a set of methods and techniques to guide them in assessing and improving data quality.


Labial adhesion is commonly seen in the paediatric and post-menopausal age groups and treatment of this condition with oestrogen cream is effective. On the other hand, postpartum labial adhesion is an unusual complication of vaginal birth except when it associated with trauma to the perineum. In that situation, treatment with oestrogen cream is usually in-effective.

A 19-year-old primipara presented 15 months after vaginal birth with difficulty in having sexual intercourse. She had sustained a perineal tear during her last childbirth at home. Pelvic examination revealed fusion of the medial aspect of the labia minora with a membrane inferior to the external urethral opening completely closing the vaginal orifice. A surgical division under anaesthesia was carried out and she resumed sexual intercourse within five days.

Postpartum labial adhesion is an uncommon complication of vaginal births and surgical division of labial adhesions is the first line of management. Good postpartum perineal care for perineal laceration following vaginal births should be encouraged to prevent apareunia.

Abstract. Registration of point clouds is a necessary step to obtain a complete overview of scanned objects of interest. The majority of the current registration approaches target the general case where a full range of the registration parameters search space is assumed and searched. It is very common in urban objects scanning to have leveled point clouds with small roll and pitch angles and with also a small height differences. For such scenarios the registration search problem can be handled faster to obtain a coarse registration of two point clouds. In this paper, a fully automatic approach is proposed for registration of approximately leveled point clouds. The proposed approach estimates a coarse registration based on three registration parameters and then conducts a fine registration step using iterative closest point approach. The approach has been tested on three data sets of different areas and the achieved registration results validate the significance of the proposed approach.

The demand for serious, systemic reform of our schools and the dramatic increase in the availability and power of technology within schools have simultaneously grown into two of the most significant trends in education today. But efforts at school reform and technology implementation often occur separately, with little coordinated planning and no mutual support. Technology and Education Reform shows how the introduction of such new instructional technologies as multimedia systems, networks, video, and microcomputers can support and further the efforts of school reform. Based on research by the National Study on Technology and Education Reform - a project of SRI International sponsored by the U.S. Department of Education - along with additional research by the authors, this book provides a framework for linking the instructional uses of new technologies to the teaching and learning goals of school reform, showing how the new roles of students and teachers as envisioned by the education reform movement can be supported by technology. The book provides concrete illustrations of how technology can be used to help both students and teachers to accomplish things they could not do otherwise. By providing examples of successful programs from around the country, the authors reveal the specific kinds of technologies that hold the most promise for increasing student learning. They show how technology can improve teacher training. And they explain what policy makers can do to accommodate the implementation of new technologies.

This paper presents an alternative approach for analyzing international competition and alliances as rent‐seeking contests that are able to capture the impure public good nature of defense spending. Two‐country Cournot and Stackelberg games are considered and comparative static results derived. A three‐country model is investigated, and alliance behavior is explored in the context of this rent‐seeking model. The conjecture that an alliance may become less effective if the allies' interests become more closely aligned is verified. Finally, the model is generalized, and a Nash‐Cournot equilibrium is computed.


Social recommendation, which leverages social connections to construct Recommender Systems (RS), plays an important role in alleviating information overload. Recently, Graph Neural Networks (GNNs) have received increasing attention due to their great capacity for graph data. Since data in RS is essentially in the structure of graphs, GNN-based RS is flourishing. However, existing works lack in-depth thinking of social recommendations. These methods contain implicit assumptions that are not well analyzed in practice. To tackle these problems, we conduct statistical analyses on widely used social recommendation datasets. We design metrics to evaluate the social information, which can provide guidance about whether and how we should use this information in the RS task. Based on these analyses, we propose a Distillation Enhanced SocIal Graph Network (DESIGN). We train a model that integrates information from the user-item interaction graph and the user-user social graph and train two auxiliary models that only use one of the above graphs respectively. These models are trained simultaneously, where the knowledge distillation technique restricts the training process and makes them learn from each other. Our extensive experiments show that our model significantly and consistently outperforms the state-of-the-art competitors on real-world datasets.

Nitrogen adsorption studies have been employed to examine the structural properties of micro-/meso-porous carbons obtained by colloidal templating and post-synthesis KOH activation. These carbons were prepared by polymerizing phenol and formaldehyde in the pores of a colloidal silica template followed by carbonization, silica dissolution and post-synthesis KOH activation. Colloidal silica was used to create spherical mesopores, while KOH activation was performed to create additional microporosity and to enlarge the surface area of the resulting carbons. Nitrogen adsorption studies showed that a single impregnation of the colloidal silica template with phenolic resin precursors afforded carbons with relatively thin pore walls which did not withstand the post-synthesis KOH activation; however, a double impregnation generated mesoporous carbons with thicker pore walls. Activation of these latter carbons with KOH created micropores in the mesopore walls without significant deterioration of the mesopore structure. The resulting mesoporous carbons possessed high specific surface areas (ca. 800 m2/g) and large single-point pore volumes (ca. 1.8 cm3/g). The post-synthesis KOH activation enlarged the surface area up to 1500 m2/g, which was achieved via the creation of microporosity. Hence, the carbon obtained by double impregnation and activation exhibited a single-point pore volume of ca. 2 cm3/g with a relatively high microporosity which attained 17% of the total porosity. High-surface-area micro-/meso-porous carbons are attractive for adsorption, catalysis and energy-related applications such as capacitors and batteries.


The paper examines the empirical determinants of consumption in Australia in the post-war period. The model provides an influential function for assets and suggests that the success of inflation in explaining the increase in the official saving ratio in the 1970s can be traced to its role in mimicking asset effects. The modeling and stylistic facts suggest that credit conditions, unemployment and income changes are important in explaining short-run movements in consumption. The fact that parameters were constant, even in a variant of the estimated model in which expectations were removed, suggests the unimportance of the Lucas critique. Orthodox life-cycle theory received only equivocal support. Demographics still play a role, but they are much weaker than would be implied by a model in which young risk-neutral agents can borrow freely to consume in advance of future income.

We revisit the trajectory planning problem for general N-link robotic manipulators. Our approach focuses on characterising the whole set of states that can be transferred to a target set of velocities without violating constraints. To achieve this, we work in the commonly utilized two dimensional projected space of the Lagrangian dynamics on a specific predefined path. The produced dynamics is a double integrator, with nonlinearities being pushed into a non-convex and state-dependent input constraint set. We approach the problem as a special reach-avoid set computation problem using ordering properties of the trajectories generated by a suitably parame-terised state feedback control law. Our results are illustrated in simulation using a realistic model of the UR5™ commercial robot.


A model of the input impedance of the toroidal permeable antenna, which is the dual of the conventional metal loop antenna, is derived, starting from Schelkunoff's transmission line description of the loop antenna instead of the electrically small limit model. The input impedance for the dipole mode is expressed in a form that has a frequency independent resistor terminating a reactive network which is called the Darlington form. Since such a circuit mimics the input impedance of the dipole modes of the spherical mode expansion, it works very well as we go beyond the electrically small limit even for magnetic antennas as large as multiple wavelengths. The realistic feed loop contribution is explicitly accounted for and results are compared with fullwave simulations of a typical toroidal antenna which shows good agreement well beyond the electrically small limit.


Nano-scale metal thin films have been extensively utilized in many fields including semiconductor, MEMS, display, and bio-medical applications. Elastic modulus of a metal thin film is a basic parameter for designing a device utilizing it, but it is difficult to measure the elastic modulus of the film when it's characteristic size is nano-scale. When a stiff thin film is compressively stressed on a soft polymer substrate, it usually forms a wrinkled pattern with a characteristic wavelength due to buckling. The wavelength is closely related to the elastic moduli of the thin film and the substrate. In this study, residually-compressed Au and Ti thin films are deposited on thick PDMS(polydimethylsiloxane) substrates and the resulting wrinkled patterns are analyzed using white light interferometer. The elastic moduli of the thin films are esi mated based on the analysis of the wrinkled patterns and the estimated elastic moduli are compared with those measured by micro tensile test.


The paper presents an acoustic training system for building acoustic models for a medium vocabulary speaker independent continuous speech recognition system. A speech database is constructed to train the acoustic models. The acoustic models are constructed, trained. A test set database is constructed to test the accuracy of the acoustic models, also 4 language models of two main types: bigram and context free grammar were built and used in tests. Our results show a 5.26 YO and 2.72 % word error rate for 1340 and 306 words bigram based language model respectively. Our results show also 0.19 % and 0.99% for 1340 and 306 words context free grammar based language models respectively.


This study is part of a series of publications of the Gallo-Roman pottery from excavations in the Valence-Avignon sector of the TGV mediterranee route. It allows us to sketch an overview of ceramic consumption from a specific sector of the Middle Rhone valley, the lower valley of the river Drome, between the Late La Tene period and the beginning of the Early Middle Ages. While very few regional workshops were found, their dynamism can be confirmed and evidence of special ties with mediterranean regions highlighted through a common morphological repertory.


Thirty-six eggplant cultivars were molecularly characterized with SRAP markers.Their genomic DNAs were amplified using 25 primer combinations.A total of 566 bands were generated,of which 102 were polymorphic with an average of 4.08 polymorphic bands per primer pair.The highest genetic similarity was 0.986 between'Wanghaqie'and'Benxizaoziqie',while the lowest was between'Fushe 1'and'Huzichangqie'.A DNA fingerprint of 36 cultivars was constructed with 8 primer combinations.Primer combination FC8ME10 could distinguish'Minchangqie'from the others,and SA1OD3 could distinguish'Dunheqie'and'Sudaqingqie'from the others.These demonstrated that SRAP was a promising marker system for detecting polymorphisms and identifying unique genotypes in eggplant.


Where there is water there is life. Life exist around numerous uses of water which makes it important for survival and luxury. Pattern of domestic water use refers to the use of water for various domestic activities. However, accurate data on pattern of domestic water use are scarce in Nigerian urban centers. This study collected data from randomly selected households in the low , medium and high density residential areas of Bauchi metropolis .The data was analyzed using Microsoft excel and presented in tables The study found out that the pattern of water use at household and per capita level were similar. The pattern were bathing which consume (45%) of total domestic water use at household level, flushing toilet (15%), cooking (5%), drinking (7%), Muslim prayer (10%), Christin prayer (1%),washing cloth (7%), washing dishes (4%), brushing teeth (1%) and so on. However, there is slight variation in the pattern of water use within the density areas where there is no water use for Christian prayer in the low and high density residential areas but only in the medium density area. Keywords: pattern, domestic, water use, density areas.


The course of male meiosis was studied in six species of Abutilon collected from different localities in North-West India. Abutilon bidentatum, A. indicum, A. muticum, A. pannosum and A. theophrasti showed gametic chromosome number n=21 and were found to be hexaploid (6x). A. ramosum was found to be diploid (2x) with chromosome number n=8. A. muticum (n=21) has been worked out for the first time. The present study revealed that genus Abutilon is dibasic having basic chromosome numbers x=7 and 8. The genetic divergence among the selected accessions of six species of Abutilon was analyzed by using ITS of rDNA as a DNA marker. The sequences of ITS showed divergence at 126 nucleotide positions. Two major clades of Abutilon species were resolved in the phylogenetic tree with basic chromosome numbers x=7 and 8. A. ramosum (x=8) lies genetically between Abutilon species with x=7 and those species of Abutilon already shifted to genus Callianthe with x=8.


ABSTRACT The urbanization policies introduced by colonial governments into former settler colonies in Africa (Kenya, Zimbabwe, South Africa, etc.) bear an uncanny resemblance. These polices aimed more at controlling the African population than judiciously managing it. Pass laws were enacted to ensure that only people with salaried employment resided in cities. They discriminated against the unemployed as well as women and children. This paper examines the implementation of such polices in Kenya from the colonial period to date. The conclusion is that, since Kenya and South Africa have parallel histories, the latter can learn from the unpleasant experiences of the former in relation to formulating and implementing urban shelter polices, particularly for low-income groups. It is argued that such policies must take cognizance of the cultural diversity and economic realities of the majority of the population. It must be homegrown and must address the key components of housing production and consumption such a...


Nonassociative division algebras have been recently proposed as an alternative way to design fully-diverse space-time codes. In particular, nonassociative cyclic algebras provide division algebras more easily than their associative counter-part. In this paper, we propose a few space-time code constructions coming from both associative and nonassociative cyclic algebras of degree 4, suitable for 4 transmit and 2 receive antennas, which furthermore exhibit good fast-decodability.


Previous work on consequentialism (especially in Theory and Decision, 1988, pp. 25– 78) has provided some justification for regarding an agent's behaviour as "structurally rational" if and only if there are subjective probabilities, and expected utility is maximized. The key axiom is that rational behaviour should be explicable as the choice of good consequences. This and other axioms will be re-assessed critically, together with their logical implications. Their applicability to behaviour in n-person games will also be discussed. The paper concludes with some discussion of modelling bounded rationality. I. THREE CONSEQUENTIALIST AXIOMS In the little space and brief time allowed to me, I shall try to impart some of the key ideas of the "consequentialist" approach to rational behaviour. At the same time, I shall try to assess its significance and to explain its limitations. Consequentialism relies on the presumption that behaviour is rational if and only if it is explicable by its consequences. More specifically, the set of consequences which can result from behaviour should depend only on the set of feasible consequences. And, as the key assumption, this should be true for an (almost) unrestricted domain of finite decision trees whose terminal nodes have specified consequences.


Effects of water temperature on coelomic pressure and ventilation in the respiratory tree of the Japanese common sea cucumber, Aposticopus japonicus were examined using the method which continuously measured the ventilation volume. With increase of water temperature, the ventilation volume per unit time in the respiratory tree increased by increasing the inhalation volume per one inhalation and the inhalation frequency per one ventilation, and decreasing the periods per one inhalation and per one exhalation. And the minimum and maximum of coelomic pressure per one ventilation increased with increasing the inhalation volume per one inhalation.


Nowadays, the focus of the business of each company should be directed towards the theory of sustainability, for the reason that it can meet all the needs of today. Sustainable development is based on a fact that does not jeopardize the opportunities of all future generations, as well as a fact that relates to economic, social and environmental aspects. Therefore, a better and more balanced life is needed for all people. Also, business needs to be based on the interconnectedness of every single aspect, which directly touches on renewable energy sources.It is necessary to preserve all those natural resources that make life easier and provide security, and also to avoid all those activities that have, and may have, a negative impact on future generations. In addition to sustainable development, it is also important to focus on corporate social responsibility and ethics, which encompasses responsibility at all levels of an individual company.In line with corporate social responsibility, businesses must integrate social and environmental concerns, and must also invest in human resources and the environment, which is necessary for further progress.


Hydrolysis of trans-dichloro(ammine)(quinoline)platinum, a novel potential anticancer drug, is believed to be the key activation step before the drug reaches its intracellular target DNA. To obtain an accurate hydrolysis mechanism for this nonclassical class of square-planar Pt(II) complex, five different models were used at the experimental temperature with the solvent effect B3LYP/PCM using hybrid density functional theory. The stationary points on the potential energy surfaces for the first and second hydrolysis steps, proceeding via a five-coordinate trigonal-bipyramidal (TBP)-like structure of transition state, were fully optimized and characterized. The most remarkable structural variations in the hydrolysis process were found to occur in the equatorial plane of the TBP-like structures of the intermediates and transition states. It was found that the explicit solvent effect originating from the inclusion of extra water molecules into the system is significantly stronger than those arising from the bulk aqueous medium, especially for the first aquation step, which emphasizes the use of appropriate models for these types of problems. The results give detailed energy profiles for the mechanism of hydrolysis of trans-dichloro(ammine)(quinoline)platinum, which may assist in understanding the reaction mechanism of the drug with DNA target and in the design of novel platinum-based anticancer drugs with trans geometries.


Daily solar radiation is a critical input for estimating plant growth and development, yet this variable is infrequently measured compared to other climate variables. This study evaluates the sensitivity of simulated maize and soybean production from the CERES-Maize and CROPGRO-Soybean modules of the Decision Support System for Agrotechnology Transfer (DSSAT) to daily solar radiation estimates obtained from traditional (stochastic, empirical, and mechanistic models) and non-traditional (satellite estimation, reanalysis datasets, and regional climate model simulations) approaches, using as an example radiation estimates for Hancock, Wisconsin, USA. When compared to observations, radiation estimates obtained from empirical and mechanistic models and a satellite-based dataset generally had smaller biases than other approaches. Daily solar radiation estimates from a reanalysis dataset and regional climate model simulations overestimate incoming daily solar radiation. When the radiation estimates were used as an input to CERES-Maize, no significant differences were found for maize yield obtained from the different radiation estimates compared to yield from observed radiation, even though differences were found in the daily values of leaf area index, crop evapotranspiration, and crop dry weight (biomass). In contrast, significant differences were found in simulated soybean yield from CROPGRO-Soybean for the majority of the radiation estimates.


This study was aimed to evaluate the effects of Cypress oil(CS) on anti-asthmatic activities in a mouse model of allergic asthma. Using an Ovalbumin-induced allergic asthma mouse model, 0.3% of CS was administered to experimental group using a nebulizer for 3 weeks on a basis of 3 times per week and 30min each time. The degree of airway hypersensitivity, the number of eosinophil in white blood cells, the number of immune cells and the change of cytokine in lung tissue were evaluated. The degree of airway hypersensitivity, the number of eosinophil, IL-5 and IL-13 levels in lung tissue, IgE in serum, the number of CCR3, CD3, CD4 cells were significantly decreased in experimental group treated with CS. These results suggested that CS may have a positive effects on Th2 cytokine and eosinophils which are major factors of asthma responses. Therefore CS might be of therapeutic value in treating asthma.


The final evaluation of the Industry Adaptability ('Normality') Index (IAI) for Q2 2017 has produced exactly the same results as our previous estimates: the Russian industrial sector has been increasingly adapting to the sluggish recovery from the crisis of 2015–2016. The IAI has come to rest at an absolute (1994–2017) peak of 76%. Therefore, more than one fourth of Russian industrial enterprises have confirmed that their current state is 'normal'.


Purpose To evaluate the accuracy of Mycobacterium tuberculosis (MTB)-RNA in the rapid diagnosis of lymph node tuberculosis (LNTB). Moreover, the difference in the diagnostic accuracy of MTB-RNA using different specimens was determined. Methods We included patients with suspected LNTB who met the inclusion criteria and retrospectively analyzed their clinical data. The sensitivity, specificity, positive-predictive value (PPV), negative-predictive value (NPV), and area under the curve (AUC) of MTB-RNA and culture were calculated and its diagnostic accuracy for LNTB was evaluated in comparison with the final clinical diagnosis. Results Overall, 285 patients were included in the study. The overall sensitivity, specificity, PPV, NPV, and AUC of MTB-RNA were 40.6%, 100.0%, 100.0%, 17.0%, and 0.70, respectively. These values were 30.8%, 100.0%, 100.0%, 16.0%, and 0.65, respectively, for tissue specimens; 34.2%, 100.0%, 100.0%, 24.6%, and 0.67, respectively, for puncture specimens; and 57.14%, 100.0%, 100.0%, 5.3%, and 0.79, respectively, for pus specimens. These values of culture were 24.4%, 100.0%, 100.0%, 13.9%, and 0.62, respectively, for all specimens; 17.6%, 100.0%, 100.0%, 13.8%, and 0.59, respectively, for tissue specimens; 25.3%, 100.0%, 100.0%, 22.4%, and 0.63, respectively, for puncture specimens; and 31.0%, 100.0%, 100.0%, 3.3%, and 0.65, respectively, for pus specimens. Conclusion The diagnostic efficacy of MTB-RNA for the rapid diagnosis of LNTB was moderate, but its sensitivity was low. The lymph node pus specimens were the most sensitive for MTB-RNA testing, followed by puncture specimens; tissues were the least sensitive. Pus specimens should be preferably obtained in case only this test is to be used for diagnosis.


An adaptive process control scheme—which uses a differential equation model, requires no differentiations in the adaptive circuitry, and no identification of the varying process parameter—was analyzed mathematically and studied on an analog computer. The adaptive loop is operative only during a transient and corrects only in the direction of mismatch between the process and model. Linear analysis of the system differential equations when the correction signal is not introduced into the controller provides a means of designing the adaptive circuitry and approximating the effect when the signal is introduced. The effects on system stability with a pure delay, measurement lag, or an additional pole in the process are presented. Computer results show that when large differences exist between the actual process time constant and the original controller setting, the adaptive feature reduces the overshoot to essentially zero.


This paper defines the concept of the ecological level of goundwater in the Haihe River valley. In the light of the specific conditions in different region: the foreplain, the middle plain and the eastern plain closing to the sea, and the differences of the exploitation and the utilization in the present situation, the paper deals with the different ecological groundwater levels in the depth and in the shallow, and puts forward the measure of keeping and returning the groundwater level.


We propose a hybrid sensorless observer for permanent magnet synchronous machines with global asymptotic stability guarantees. Exploiting the constraint of the rotor flux on a circle of unknown radius, we design an integrator system with periodic jumps triggered by a clock to generate a linear regression containing the flux estimation error. Then, a normalized projected gradient descent identifier provides the observer estimates. For the closed-loop system, it is shown that there exists a robustly globally asymptotically stable compact attractor, which, additionally, ensures zero estimation error if appropriate Persistency of Excitation (PE) conditions are satisfied. In this respect, sufficient conditions ensuring PE are provided for the angular speed and the clock period.


The present paper describes the synthesis and structural features of platinum(II) and rhodium(I) complexes of some benzothiazolines derived by the condensation of various heterocyclic aldehydes viz. 2-pyridinecarbaldehyde, 2-furancarbaldehyde, and 2-thiophenecarbaldehyde. The resulting complexes have been characterized by elemental analyses, conductance measurements and molecular weight determination. The mode of bonding and geometry of these complexes have been suggested on the basis of IR, 1H NMR, electronic spectra, and magnetic studies.

With the Standard Model being unable to describe the observed baryon asymmetry or dark matter density in the universe, many models of New Physics introduce heavy neutrino species as a possible explanation for these effects. Dirac or Majorana neutrinos with masses above the electroweak scale could be produced at future linear e+e− colliders, such as the Compact LInear Collider (CLIC) or the International Linear Collider (ILC). We studied the possibility of observing production and decays of the heavy neutrinos in the qql final state at ILC running at 500 GeV and 1 TeV and CLIC running at 3 TeV. The analysis is based on the WHIZARD event generation and fast simulation of the detector response with DELPHES. Dirac and Majorana neutrinos with masses from 200 GeV to 3.2 TeV are considered. Estimated limits on the production cross sections and on the neutrino-lepton coupling are compared with the current limits coming from the LHC running at 13 TeV, as well as the expected future limits from hadron colliders. The obtained results are stricter than any other limit estimates published so far.


The role of the artist's intention in the interpretation of art has been the topic of a lively and ongoing discussion in analytic aesthetics. First, I sketch the current state of this debate, focusing especially on two competing views: actual and hypothetical intentionalism. Secondly, I discuss the search for a suitable test case, that is, a work of art that is interpreted differently by actual and hypothetical intentionalists, with only one of these interpretations being plausible. Many examples from many different art forms have been considered in this respect, but none of these test cases has proved convincing. Thirdly, I introduce two new test cases taken from contemporary visual art. I explain why these examples are better suited as test cases and how they lend support to the actual intentionalist position.

Attenuated Total Reflection infrared spectra were obtained for rough and spheroidal powders made from an amorphous polymer. The spectra were recorded with a polarizer to obtain both parallel and perpendicular components of the spectra separately. The results were compared to both theoretical predictions and experimental results for the same material examined as a film. It was found that the relative absorption intensities of the two polarization spectra recorded of the film agreed well with the theory for films. However, the powdered samples showed unexpected increases in absorption intensities for the perpendicular spectra. The intensities of the absorptions for perpendicular polarization were about 45% greater than for films as measured by the ratio of relative effective thicknesses. Implications for interpretation of the spectra of powdered materials are discussed.

The theory of poroelasticity for the elastic region below pore collapse by means of three different loading paths gives the possibility to compare the static and dynamically determined Biot coefficient for a set of experimental data with uniaxial loading on outcrop chalk performed with different levels of pore pressure. The chalk is oilsaturated Lixhe chalk from a quarry near Liege, Belgium, with a general porosity of 45%. Additionally, we compare the theoretical lateral stress to the experimentally determined lateral stress at the onset of pore collapse. The static Biot coefficient based on mechanical test results is found to be lower than the pretest dynamic Biot coefficient determined from elastic wave propagation for the loading path and with less deviation under depletion. The calculated lateral stress is lower than the experimentally measured lateral stress depending on loading path. An explanation to this behaviour is pore pressure build up.


This study reports on the structural characterization and physicochemical properties of surface modified starch particles (SPs). The surface of the SPs were patterned via controlled deposition of cetylpyridinium bromide (CPB) at the solid-solution interface with incremental CPB loadings, denoted as SP-CPBX, where X = 0.5, 2.5, or 5.0 mM CPB. The surface patterned SPs were characterized by several complementary methods: spectroscopic (NMR, FT-IR, Raman, and SEM), thermoanalyt-ical (DSC, TGA), powder X-ray diffraction (PXRD), gravimetric-based solvent swelling, zeta-potential () and particle size distribution (PSD). NMR spectral results reveal that CPB is bound at the starch-solvent interface via the pyridyl head group, whereas the tertiary structure of the SPs was maintained over the range of CPB doping, as revealed by SEM and PXRD re-sults. The -value results of the SP-CPBX systems reveal negative -values at the starch surface, where tunable surface properties occur at variable levels of CPB surface pa...

Under the situation that the Chinese government attaches great importance to the inheritance and development of the national culture, the research on the Yang Opera of Wuling Mountain area has important practical significance. Yang Opera in Wuling Mountain Area has the characteristics of the various forms and Buddhism cultural environment. Basically there are three forms of Yang Opera in Wuling Mountain area, namely, ritual Yang Opera,Yang Opera combining ritual and opera, and folk show Yang Opera. In the Wuling Mountain area, the spread of buddhism thought was earlier than Yang Opera. Yang Opera was affected by the buddhism culture at the beginning of its coming. The culture blending has experienced the time process of culture clash,penetration and the intermixing.


This research study attempts to explore the new route of nitrogen removal called the Complete Autotrophic Nitrogen removal Over Nitrite process (CANON) to enhance the nitrogen removal in constructed wetlands. To achieve high-rate nitrogen removal via CANON, a single stage tidal flow constructed wetland system was adopted by implementing internal downflow recirculation, shorter unsaturated time, and long saturated time. It was found that the recirculation strategy with shorter unsaturated time would limit the oxygen supply, which favoured partial nitrification and the anammox process. High inorganic carbon could promote both partial nitrification and anammox activities, providing a strong selective method to maintain the CANON route. By combining the control of oxygen supply (internal recirculation, six cycles a day) and high influent inorganic carbon concentration of 150 mg/L, this study achieved ammonium and total nitrogen removal of 98% and 67%, respectively, from synthetic domestic


This paper is an intervention in the debate inaugurated by Peter Harrison in 2002 when he called into question the validity of what has come to be called 'the voluntarism and early-modern science thesis'. Though it subsequently drew support from such historians of science as J. E. McGuire, Margaret Osler, and Betty-Joe Teeter Dobbs, the origins of the thesis are usually traced back to articles published in 1934 and 1961 respectively by the philosopher Michael Foster and the historian of ideas Francis Oakley. Central to Harrison's critique of the thesis are claims he made about the meaning of the scholastic distinction between the potentia dei absoluta et ordinata and the role it played in the thinking of early-modern theologians and natural philosophers. This paper calls directly into question the accuracy of Harrison's claims on that very matter.


A blind multiuser receiver is proposed for multiuser detection of UWB systems in a realistic indoor channel. The proposed blind multiuser receiver is based on the constant-modulus algorithm (CMA), which is known to provide satisfactory performances in a blind setting. In order to overcome the CMA interference capture problem typical of a multiuser scenario, we propose to adopt a two stage receiver: in the first stage, partial ISI and MA1 suppression is achieved by exploiting the desired user signature structure properties; in the second stage, based on CMA, the residual MAI and the ISI are removed, and the desired symbols are reliably recovered. Computer simulations show that, the proposed detector achieves good performances .


Data scientists follow individually established workflows and use customized tool chains to deal with complex data analysis scenarios. Novel tools, which aim to support their work, must not disrupt these proven technical environments and must integrate with their existing tool chains in order to further enhance their productivity. Augmenting data science workflows usually requires to explicitly load data sources into additional tools where they are processed in isolation and exported again for further usage. There is currently no evolvable mechanism to augment data science workflows with additional functionality without mandatory workflow disruption. To overcome this problem, we introduce a proxy driver for augmenting data science workflows. Our driver provides proxies of Java Database Connectivity (JDBC) objects and is easily evolvable through a plugin system. Driver instances can be synced with a remote plugin repository. Currently, two different driver plugins enable query-driven data ingestion as well as query-driven data profiling.


OF THESIS SH-WAVE REFRACTION AND REFLECTION INVESTIGATION OF QUATERNARY GEOLOGY―CENTRAL UNITED STATES SEISMIC OBSERVATORY The Central United States Seismic Observatory (CUSSO) consists of an array of vertical strong motion accelerometers and medium period seismometers that penetrate 585 m into the Mississippi Embayment sediments and terminates into Paleozoic bedrock. The array is located in the New Madrid Seismic Zone within the upper embayment. The thick unconsolidated Quaternary sediments have the potential to influence strong motions; understanding how these sediments affect ground motion is the goal of the CUSSO array. Nine SH-wave refraction and five P-wave common midpoint reflection surveys were collected within a 1 km radius around the CUSSO borehole in order to characterize the local seismic stratigraphy. Three major seismic boundaries from SH-wave refraction and six P-wave continuous reflection boundaries were interpreted. Combined, both methods were used to characterize seismic horizons (Quaternary to Paleozoic) around the CUSSO in terms of velocity and depth. Faults in the area are subparallel and northeast-southwest trending. Some faults appear to deform Eocene and Quaternary sediments, although no surface expression has been found.


By means of computational physics,numerical intergration,mathematcal software and computer language MATLAB,the author conducts the numerical study and analysis of the time when an object moves along different paths.The study has shown that under the condition of the same movement (displacement),there exists a critical value of the moving time and speed when the object moves along both different curve paths and straight line path. And the time is the shortest for cycloidal path when the object moves along the different curve lines.The study of the issue is of great significance for selecting and designing of the path.
