This article used copper ion-selective electrode method to research complex percentage of dissolved humic acid and Cu2+ metal ions by a change of the influencing factors such as pH,ionic strength and copper ionic concentration.It studied the main influence factors on the complexation.The result indicated that with the increasing of pH value,the complexation capacity was increased generally.And the complex percentage is more than 94% under the experimental conditions.With the increasing of copper ionic concentration,the percent chelation was increased.However,along with ionic strength increasing,the complexation capacity was decreased.


We experienced the case of an 80 year-old female with a malignant lymphoma of the larynx. She had complained of hoarseness for the previous three months. A tumor was found in the right false cord, and its pathological diagnosis was a B cell lymphoma (diffuse mixed type). She was given a combined chemotherapy (CHOP) protocol. A hepatoma and lung tumor were then discovered by X-ray and MRI examinations. Therefore, radiation was added for the primary laryngeal and lung tumors, and the hepatoma was treated by transcatheter arterial embolization. The laryngeal and lung tumors were well controlled, but the hepatoma was still present at 6 months after her hospital discharge.

In this study, the effects of antiarrhythmic drugs on the reentrant pathway in paroxysmal supraventricular tachycardia (PSVT) were evaluated by observing the changes of conduction block cycle length. And this study was aimed to determine whether the drug responses could be predicted by characterizing the reentry path- way. Seventy-three patients with clinically documented PSVT without preexcitation were carried on electro-physiologic studies between November, 1986 and April 1990 in Severance Hospital, Yonsei University were reviewed. The study group included 35 males and 38 females with ages ranging from 16 to 67 years (mean±SD:40±15). The mean duration of symptom was 10.9±9.5 years. They had experienced paroxysmal tachycardia once per week to once in 6 months (mean frequency: 5 per year). All patients had structurally normal heart except the 2 Ebstein`s anomaly. The induction of tachycardia and the determination of mechanism of PSVT were performed by baseline electrophysiologic study in drug free status, The effects of drugs were assessed by the intravenous administration of procainamide 20 mg/kg, flecainide 2 mg/kg, verapamil 0.15 mg/kg, digoxin 0.75 mg, and digoxin 0,75 mg plus propranolol 0.15 mg/kg. The response to drug was defined as the not-induced SVT or the induction of nonsustained SVT after drug administration. 1) Fourty-nine patients had atrioventricular (AV) reentrant tachycardia using concealed bypass tract(CBT) and twenty-four patients had atrioventricular nodal reentrant tachycardia. In AV reetry using CBT, procainamide prevented induction of sustained tachycardia in 38 of 45 patients (84%), flecainide in 23 of 30 patients(77%), verapamil in 34 of 39 patients(87%), digoxin in 4 of 17 patients (23%), and digoxin plus propranolol in 7 of 14 patients(50%), In AV nodal reentry, procainamide prevented induction of sustained tachycardia in 19 of 22 patients (86%), flecainide in 9 of 10(90%), verapamil in 20 of 22 patients(91%), digoxin in 10 of 17 patients(59%), and digoxin plus propranolol in 9 of 13 patients(69%). 2) In AV reentry using CBT, procainamide and flecainide induced significant prolongation of the ventriculoatrial block cycle length (VABCL) in responder group. Also the atriventricular block cycle length (AVBCL) was prolonged significantly, but not increased above the tachycardia cycle length. Verapamil, digoxin and digoxin plus propranolol showed significant prolongation of AVBCL, but not of VABCL. 3) In AV nodal reentry, procainamide and flecainide induced significant prolongation of VABCL in responder group, and AVBCL was also prolonged but not increased above the tachycardia cycle length. Verapamil, digoxin and digoxin plus propranolol induced significant prolongation of both AVBCL and VABCL in responder group. 4) In patients with AV reentry, there was no significant difference of baseline VA block cycle length between responders and non-responders for procainamide and flecainide. But the patients having the 260 millisecond or more of block cycle length were all responded to procainamide except 1 case and all to flecainide. 5) The procainamide and flecainide had a strong concordant relationship in drug response for AV reentry(p<0. 001). With the avove results, it is noted that the procainamide and flecainide prevent induction of reentrant supraventricular tachycardia by selectively depressing the conduction over retrograde pathway of reentry circuits in responders with AV reentry using CBT and AV nodal reentry. Also it is noted that the verapamil, digoxin and digoxin plus propranolol prevented induction of SVT by depressing the conduction over antegrade pathway in responders with AV reentry using CBT, and over antegrade (AV nodal slow) and retrograde (AV nodal fast) pathways in responders with A V nodal reentry. And it can be suggested that the baseline block cycle length of accessory pathway has a limited value in predicting the drug responses in AV reentry using CBT. Also it is noted that in AV r


The contact between aggregates is an important feature of asphalt mixture skeleton. By comparing skeleton-dense and suspended-dense structure asphalt mixture test results, this paper studied the distribution characteristics of coarse aggregate contacts by using two-dimension digital image processing technique. The results indicate that skeleton-dense asphalt mixture has more homogeneous distribution of contact points, and a relatively stable skeleton structure than suspended-dense mixture. In two-dimension image, homogeneous distribution of contact points and little unrestrained coarse aggregates are two evident characteristics of asphalt mixture with good rutting resistance. The rutting resistance of asphalt mixture has no correlation with contact points, but is related to the spatial distribution of the contact points.


In Japan, to reduce the health risks associated with hazardous air pollutants, Environmental Quality Standards have been set for certain chemicals in ambient air, and national or local government and industry are required to ensure that the concentrations of those chemicals remain below the Environmental Quality Standards. Guideline Values have also been set to reduce health risks resulting from hazardous air pollutants in the atmosphere. Whether carcinogenicity has a threshold or not is an important factor for risk assessments and for setting Environmental Quality Standards and Guideline Values for carcinogens. In the ``Guidelines on Health Risk Assessment Methods for Hazardous Air Pollutants'', carcinogenic air pollutants are proposed to be grouped according to judgment of whether carcinogenicity has a threshold. However, factors for determining the existence, and actual value of threshold of carcinogenicity have not yet been identiˆed. Our research group believes that susceptibility to genotoxic carcinogens is a determinant of carcinogenic threshold, and that metabolic activation of mutagens, excision DNA repair, translesional DNA synthesis, and apoptosis are the main factors determining susceptibility. We have investigated metabolic activation (especially the level of phase II-drug metabolizing enzymes) as a factor in susceptibility to genotoxic carcinogens. Our studies of mice deˆcient in Nrf2 (a gene of a transcription factor for inducing phase II enzymes ) suggest that expression of phase II enzymes prevents the induction of certain mutations caused by genotoxic carcinogens such as benzo[a]pyrene.


In this paper, we describe an application of neural network for the classification of natural materials textures. We developed this solution in the context of leather quality control. This leather is used in car sits manufacturing. The aim of this control is to make sure of the compatibility of every visual aspect in the whole car. This job is currently processed by human experts that cannot inspect every sits with the same attention. The automation of such a process is very complicated because it is necessary to build a model of human vision in order to take into account how a texture is interpreted as an aspect.


We present a study of resonant vibrational coupling between adsorbates and an elastic substrate at low macroscopic coverages. In the first part of the paper we consider the situation in which adsorbates form aggregates with high local coverage. Based upon our previously published theory, we derive formulas describing the damping rate of adsorbate vibrations for two cases of such aggregation: (i) adsorbates attached to step edges and (ii) adsorbates forming two-dimensional islands. We have shown that damping is governed by local coverage. Particularly, for a wide range of resonant frequencies, the damping rate of adsorbates forming well-separated islands is described by the damping rate formula for a periodic overlayer with the coverage equal to the local coverage in the island. The second part of the paper is devoted to facilitating the evaluation of damping rates for a disordered overlayer. The formula describing the damping rate involves the parameter β, which is related to the local density of phonon states at the substrate surface and does not allow a closed-form representation. For substrates of isotropic and cubic symmetries, we have developed a good analytical approximation to this parameter. For a vast majority of cubic substrates the difference between the analytical approximation and numerical calculation does not exceed 4%.


Abstract A national land classification developed by the Institute of Terrestrial Ecology (ITE) was used to stratify a sample‐based survey of land cover and linear boundary features within the catchment of the River Tyne, Northern England. A total of 115 1‐km grid‐squares from four land classes representative of Lowland Pastoral, Lowland Arable, Marginal Upland and Upland landscapes were surveyed in the field. The land classes are described with an emphasis on the variability of land cover types and linear features. Considerable variation between squares of the same land class was observed, but statistically significant differences between the land classes were identified. Variation in the lengths of linear features was related to the land cover compositions of sample squares. The origins of the intra‐land class variation and the application of the ITE land classification in large‐scale surveys are discussed.


U.S. President Joe Biden took his oath after being victorious in the controversial U.S. elections of 2020. The polls were conducted over postal ballot due to the coronavirus pandemic following delays of the announcement of the election's results. Donald J. Trump claimed that there was potential rigging against him and refused to accept the results of the polls. The sentiment analysis captures the opinions of the masses over social media for global events. In this work, we analyzed Twitter sentiment to determine public views before, during, and after elections and compared them with actual election results. We also compared opinions from the 2016 election in which Donald J. Trump was victorious with the 2020 election. We created a dataset using tweets' API, pre-processed the data, extracted the right features using TF-IDF, and applied the Naive Bayes Classifier to obtain public opinions. As a result, we identified outliers, analyzed controversial and swing states, and cross-validated election results against sentiments expressed over social media. The results reveal that the election outcomes coincide with the sentiment expressed on social media in most cases. The pre and post-election sentiment analysis results demonstrate the sentimental drift in outliers. Our sentiment classifier shows an accuracy of 94.58% and a precision of 93.19%.


Particle symbols and Feynman diagrams often used in particle physics can be generated by a word document processor. Standard office packages have their built in symbols such as solid-line, dashed-line, arrows, etc. which are also used in particle physics. Three symbols corresponding to photon, gluon and fermion line are not present in the standard office packages. By importing these two symbols and using the built in symbols, tree-level Feynman diagrams can be easily generated in an office program.


Photo-oxidation (in the presence of eosin Y as a sensitizer) of isohemagglutinating sera destroyed their agglutinating activity gradually, but did not seem to convert any of the agglutinins studied into inhibiting ("incomplete" or "blocking") antibody.


2. Pathophysiology 2.1. Chronic venous insufficiency is caused by: • Superficial venous reflux (varicose veins, v. saphena magna / parva incompetence) • Deep venous reflux: o Primary o Secondary to DVT (post-phlebitic/post thrombotic syndrome), AV fistulas, AV-malformation • Perforator vein reflux not as important as an isolated abnormality, usually in association with superficial or deep venous reflux • Deep vein occlusion (e.g post thrombotic, trauma, extrinsic compression, tumor) • Impaired muscle pump (neurological, musculo-skeletal)


An orally bioavailable inhibitor of activin A receptor type 1 (activin receptor-like kinase 2; ALK2; ALK-2; ACRV1), with potential antineoplastic activity. Upon oral administration, ALK2 Inhibitor T P-0184 targets, binds to and inhibits the activity of ALK-2. T his prevents ALK2-mediated signaling and inhibits cell growth in ALK-2-overexpressing tumor cells. In addition, in cancer and inflammatory conditions, ALK-2 is upregulated in response to increased signaling of pro-inflammatory cytokines, especially interleukin-6 (IL-6), and enhances the secretion of hepcidin, a peptide liver hormone and a key modulator of iron homeostasis. Blocking ALK-2-mediated pathways in inflammation and cancer leads to a decrease of hepcidin expression and restores plasma iron levels, thereby preventing low serum iron levels and anemia of chronic disease (ACD). ALK-2, a serine/threonine receptor kinase, is constitutively activated due to activating mutations or upregulated upstream signaling pathways in inflammatory conditions and certain types of cancer.

The first glass layer comprises a plurality of glass elements, wherein the first and second glass layers are fused together. The invention also describes a method for manufacturing the above tile. The method comprises the steps of aligning the above plurality of glass elements in a layer so as to realize the butt joint or interlocking of the adjacent edges; or aligning the above plurality of glass elements in any suitable arrangement; and fusing the glass elements together so as to form a single layer through the fused glass elements.


This paper illustrates the intricacies associated with the design of revenue-maximizing mechanisms for a monopolist who expects her buyers to resell in a secondary market. We consider two modes of resale: the first is to a third party who does not participate in the primary market; the second is inter-bidders resale, where the winner in the primary market resells to the losers. The main contribution is in showing how revenue-maximizing mechanisms can be designed investigating the optimal informational linkage with the secondary market. To control the price in the resale game, the monopolist must design an allocation rule and a disclosure policy that optimally fashion the beliefs of the participants in the resale market. We show that it is generically impossible to maximize revenue through deterministic selling procedures and disclosing only the decision to trade with a particular buyer. To create the optimal informational linkage, the monopolist may need to induce stochastic allocations and disclose also the price paid in the primary market. The optimal allocation rule and disclosure policy maximize the expected sum of the bidders' resale-augmented virtual valuations under the constraints imposed by the sequential rationality of the bidders' offers in the resale game.


This paper reports the nucleation and growth of lepidocrocite (γ-FeOOH) crystallites in supramolecular polymer multilayers. Organized, polymeric thin films were formed by the layer by layer deposition technique that consisted of adsorbing alternate layers of a polycation and a polyanion on a quartz substrate. Nucleation of nanoparticles was initiated by absorbing ferric nitrate in the thin film polymer matrix, followed by hydrolysis with ammonium hydroxide. Repeating the above process resulted in an increase in the density of the nanoparticles initially formed and further growth in the dimensions of the crystallites with the number of absorption and hydrolysis cycles. Analysis of the UV−visible absorption spectra of the films revealed the formation of lepidocrocites, which was confirmed by FTIR and selected area electron diffraction (SAED) studies. An important feature of this work is that lepidocrocite (γ-FeOOH) is formed instead of akaganeite (β-FeOOH), which is generated when ferrous chloride is used a...


5G is one of the emerging technologies nowadays. An efficient antenna design is a vital component for this technology. This paper presents the optimization of a 5G antenna that operates in 28 GHz frequency band. The rectangular inset- fed patch microstrip antenna that used substrate RogerRT5880 was previously designed in a CST software. Using the design, it was simulated in MATLAB and optimized using the Surrogate model Assisted Differential Evolution for Antenna synthesis (SADEA). To optimize the directivity gain and improve the return loss, the length of the patch, the width of the patch and the width of the notch were modified. The results showed an improvement in directivity gain, return loss and bandwidth. The directivity gain improved to 8.66dBi. The return loss became - 19dB. The reflection coefficient was found below -10 dB from GHz to 30.6 GHz which showed an improved impedance bandwidth from 1.1 GHz to 2 GHz. Along with the presentation of the improved results, this paper highlighted the importance of optimization techniques in the field of communications.


Previous academic research has documented that people experience disutility from potentially being exploited by others beyond what this exploitation may do to their wealth. Such a tendency was labeled as the demand for accountability in accounting or more broadly as betrayal aversion in other fields such as sociology. Since the environment is not static for a decision maker, it is important to understand not only that betrayal aversion exists but also how/if its impact on individual decision making varies in response to environmental changes. In this study, we investigate if changed economic conditions (i.e., an economic downturn or upturn) would affect the level of betrayal aversion and its impact on a principal's internal control system choices. The results of our experiment suggest that while the level of betrayal aversion does not change with changed economic conditions, its relative importance on principals' control system choice decreases (does not change) in an economic downturn (upturn). These findings are consistent with the notion that loss aversion dominates betrayal aversion in control system choices when decision makers are facing an economic downturn. This study suggests that the initial decision motivated by betrayal aversion cannot be assumed to be unaltered when the environment changes.


The great number of records belonging to the "Arxiu del Gran Priorat de Catalunya", kept in the Archiv of the Crown of Aragon (Barcelona), has suffered a lot of changes of fortune all along the centuries. This article calls the attention about 192 parchments, a book of Privileges and two books on inquisitions against Templars that have at last been localized in the Capitular Archiv of the Barcelona Cathedral.


A highly sensitive spectrophotometric FIA method is proposed for the determination of vanadium using the vanadiumcatalyzed oxidation of o-phenylenediamine with bromate at pH 4.0 and 50° C in the presence of gallic acid as an activator. The same calibration graph with a linear range of 0 8 μg l-' was obtained for V(IV) and V(V) by the proposed method. The detection limit and typical sampling frequency were 4 ng 1-1(0.8 pg) and 30 samples h-', respectively. Iron ions of up to 5 μg 1-' and humic acid of up to 3000 μg 1-1 were tolerable in the determination of 0.2 μg 1-' of vanadium; the latter value was markedly improved compared to that with a manual-batch fluorometric method. The proposed method was successfully applied to analyses of lake, river, ground, rain and tap water samples containing vanadium down to 0.02 μg 1-1


The most recent physical education teacher education (PETE) standards were published in 2009. Since that time, institutions seeking accreditation through the Council for the Accreditation of Educator Preparation (CAEP, formerly NCATE) have based their programs' assessments and data collection on these standards. The authors of this article compiled data from several specialized professional association (SPA) accreditation review cycles to ascertain where programs are most and least successful in meeting these standards. Common issues are identified and recommendations for avoiding common errors are offered in order to assist PETE programs with future SPA reports.

In this paper we investigate an alternative characterization of the inverse AM/AM and AM/PM transfer curves of a high power amplifier (HPA), defining an adaptive algorithm for the optimum adjustment of the coefficients in a memoryless rational-based model used to pre-distort a base band signal with complex modulation in a quadrature non-linear model. Input signal statistics are unknown so its influence in the estimation is analyzed and compensation results are shown and compared with other previously proposed methods.


Globalization as an ongoing process allows and promotes the development of economy of big countries as well as developing countries that are seeking their place in the global market. Interactive communication has been enabled between people, companies, civil society organizations and other institutions, whose needs can be met over the internet anywhere in the world and at any time. Also, professional and competent human resources are needed and therefore it is necessary to invest in new knowledge, innovation, new technologies and lifelong learning. In this environment, management sets its strategic goals through which it will be able to carry out the plans for the sale of products or services. Nowadays, a manager has to have interdisciplinary skills and lifelong education because only in this way it is possible to respond to the constant and rapid changes in the world. We are witnesses that Europe has reunited in order to compete with the less developed countries with their products and services. Europe has long refused to accept the managerial style of governance, particularly in public administration and is therefore far behind the U.S., but also the Third World countries. Until recently, European public administration was more focused on the implementation of laws and regulations and less on managerial governance of the U.S. type. Global environment requires the continuous research, monitoring competition, innovation and the ability to change rapidly.


This article is concerned with the contribution of schoolchildren towards the food production drive in England during the Second World War. After a consideration of the broader aspects of the farm labour problem between 1940 and 1950, the focus is directed towards the various official and semi-official schemes by which children were involved in summer and autumn harvest work. Logistical, operational and financial issues are reviewed in some detail along with various aspects of gender and attitudes of interested parties towards the scheme. While harvest camps generally seem to have been a positive and enjoyable experience for school children, there remains a great deal of scope for oral history studies to elucidate the finer details. The singular contribution of home-based farming to the survival of the United Kingdom during the Second World War and the critical years immediately following the conflict was widely realized at the time and has subsequently been recognized by a variety of contemporary scholars. If Lord Murray's magisterial official history occasionally exaggerates the achievements of the wartime food production campaign, the fact remains that by 1940–1 two million extra acres of grassland had been converted to arable so that the land area under wheat and potatoes advanced by 43,000 acres and 128,000 acres respectively, alongside an expansion of 1.48 million acres of other grains and 56,000 acres of forage crops. As more pasture land fell under the plough in 1941–4, the acreage of permanent grass declined by 34 per cent from that of 1938, while the area cropped to potatoes alone exceeded its pre-war level by some 92 per cent. The dramatic and well-documented increases in output were, of course, orchestrated by the Ministry of Agriculture through its County War Agricultural Executive Committees (established under Regulation 66 of the Defence (General) Regulations of 1939), with the Ministry of Food being mandated to oversee the marketing and distribution of the produce. Agricultural production and marketing were, in effect, subject to the strictest of controls and surveillance as CWAECs attempted, sometimes controversially, to enforce orders and maintain standards. 1 R.

In a flexible connection for two pipe sections with a metal bellows (3) gastightly connected axially on both sides to connectors (1; 2), the sides of the connectors (1, 2) towards the bellows (3) have radially widened end sections (4, 5) with cylindrical end regions (10, 11). There are also a damping insert (12) coaxial with the bellows, extending over its length and integral therewith and an internally effective heat protector (16) for the bellows (3). The damping insert (12) surrounds the bellows (3) on the outside and the bellows' corrugations (3') lie against it. The lateral end regions of the damping insert (12) are held in the end sections (4, 5) without a clamp and are supported radially outward thereby. The connectors (1, 2) are secured together via a spring (13) radially surrounding the damping insert on the outside. The heat protector takes the form of a pipe section (16) running coaxially with the bellows (3) with a radial distance inside it and is secured to the forward connector (1) in the direction of flow.


Given a long and strong societal bias in favor of public disclosure about important issues, including legal issues, the modest moves by South Carolina's federal and state judiciary favoring less secrecy in lawsuit settlements ought to have gone unnoticed for being predictable and unexceptionable. Instead, the South Carolina jurists' efforts to bring sunshine to the settlement process have garnered significant national attention and a fair amount of opposition. Despite our nation's bias in favor of accurate, honest disclosure about important public matters, South Carolina finds itself today amongst a distinct minority of states featuring a statutory or court-rule created restraint on secrecy agreements in the settlement context. This Article examines the importance of openness in court-related matters from a somewhat unconventional perspective. It argues that, in many cases, lawyers and judges need look no further than their professional ethical obligations in order to decide that they cannot participate in furthering secrecy agreements relating to legal disputes.


The development of a platform for the evaluation of control algorithms of functional stimulators commanded by the surface electromyogram of the same electro-stimulated muscle is described. It is conformed by a stage of conditioning and other processing. The first carries out the removal of the electrical stimulus artifact and the amplification and filtering of the signal. The second stage provides a processing environment for the implementation of algorithms and allows the creation of a control signal to the stimulator. The prototype was tested with simulated and real signals, evaluating the removal of the artifact, signal amplification, the frequency response of the filters, adquisition and storage of data. The results showed good performance of the artifact's suppressor, very good SNR of the signal conditioned and high reliability in storing the digitized data, obtaining a suitable tool for rapid assessment of algorithms.


The E665 spectrometer at Fermila.b measured Deep-Inelastic Scattering of 490 GeV /c muons off several targets: Hydrogen, Deuterium, and Xenon. Events were selected from the Xenon and Deuterium targets, with a range of energy exchange, $\nu$, from 100 GeV to 500 GeV and for large ranges of $Q^2$ and $X_{Bj}$: 0.1 (GeV /$c)^2$ < $Q^2$ < l00(GeV /$c)^2$ and 0.001 < $X_{Bj}$; < 0.1. The presented results include comparisons of distributions .of produced hadrons, as functions of the hadron variables $Z$ and $\phi$. In both variables, the dependence of the distributions upon the rank of the hadrons, in terms of their momenta., has been examined. The longitudinal energy distributions (Z) show no nuclear dependence, even in the kinematic region of Shadowing. The asymmetry of the distribution of hadron azimuthal angle is demonstrated, but no nuclear dependence is observed in this asymmetry. The asymmetry exhibits strong dependence upon the rank of the hadron.


OF THESIS ZAPPA'S REMEMBRANCE OF A FORGOTTEN STYLE: THE RELATIONSHIP BETWEEN FRANK ZAPPA AND DOO-WOP AS ILLUSTRATED IN CRUISING WITH RUBEN & THE JETS One of Zappa's many cherished styles of music was the doo-wop of the mid-1950s through the early 1960s. His love for the style culminated in 1968 with a poor-selling and often forgotten doo-wop record, Cruising with Ruben & The Jets. While the record earned little praise from critics and fans, Zappa considered it as a landmark of his early career, as evidenced in his autobiography. This thesis investigates Zappa's relationship to doo-wop and "perversion" of the style as it culminated in Cruising. As revealed through autobiographical entries and interviews with Zappa, Ray Collins, and other collaborators, Zappa devised his unique doo-wop style from the early onset of his career until Cruising's release in 1968. Moreover, he utilized his collagist composition techniques similar to those of postmodern American art music composers of the 1960s such as George Rochberg and David Del Tredici. Although outside of the realm of art music, Cruising is a highlight of Zappa's early style and one of his finest representations of postmodernity.


Researchers developed a new forensic tool for tracing the origins of timber that could enable enforcement of antideforestation legislation in the European Union.


Systemic risks arising from underlying interdependences can create havoc at an industry level and are often too formidable for any single firm to manage. The contagion effects of these risks, including the recent financial crisis, offshore oil spills, and the Japanese nuclear disaster, have upended industry practices. Sometimes they have even pulled economies apart at the seams. We recommend that leaders heed models of cooperative behavior found in nature by engaging in "Pelican Gambits," which we define as strategic moves towards cooperation in highly competitive economic environments for the purpose of limiting risk to one's firm, the industry and society.


Strong detections have been made of both the 18.7 microns and 33.4 microns lines of S III in the irregular galaxy M82. This represents the first detection of the 33.4 microns line in an extragalactic object. These measurements sample the ionized gas component which dominates the observed infrared forbidden line and infrared hydrogen recombination line emission. From the ratio of the line fluxes an electron density of 120 (+ 280, - 120) per cu cm is deduced. This result is in agreement with previous estimates of the density derived from high-frequency radio continuum measurements and an assumed emitting volume. They impose further constraints on possible starburst models.


It is commonly believed that light cannot couple to the collective excitations of the fractional quantum Hall effect (FQHE). This assumption relies on Kohn's theorem that states that electron-electron interactions decouple from homogeneous electromagnetic fields due to galilean invariance. Here, we demonstrate that the existence of an edge breaks Kohn's theorem, and enables coupling of cavity light to the plasmonic edge modes of the FQHE. We derive the coupling using the FQHE bulk-boundary correspondence and predict the formation of experimentally detectable plasmon polaritons. We find that a single cavity mode leaves the system's topological protection intact. Interestingly, however, a multimode cavity mediates plasmon backscattering, and effectively transforms the edges of the 2D FQHE into a 1D wire. Such cavity-meditated nonlocal backscattering bodes the breakdown of the topological protection in the regime of ultra-strong photon-plasmon coupling. Our analytical framework and photoelectric findings pave the way for investigating the topological order of the FQHE via optical spectroscopic probes and provide new opportunities to control FQHE edge excitations using light.


We study accretion disk emission from eight Seyfert 1–1.5 active galactic nuclei (AGN) using far-ultraviolet (FUV) (1300–1800 Å) slitless grating spectra acquired with AstroSat/UVIT. We correct for the Galactic and intrinsic extinction, contamination from the host galaxies, narrow and broad-line regions, Fe ii emission, and Balmer continuum, and derive the intrinsic continua. We use Hubble Space Telescope COS/FOS spectra to account for the emission/absorption lines in the low-resolution UVIT spectra. We find generally redder power-law (f ν ∝ ν α ) slopes (α ∼ −1.1 to 0.3) in the FUV band than predicted by the standard accretion disk model in the optical/UV band. We fit accretion disk models such as the multitemperature disk blackbody (DISKBB) and relativistic disk (ZKERRBB, OPTXAGNF) models to the observed intrinsic continuum emission. We measure the inner disk temperatures using the DISKBB model for seven AGN. These temperatures in the range ∼3.6–5.8 eV are lower than the peak temperatures predicted for standard disks around maximally spinning supermassive black holes accreting at Eddington rates. The inner disks in two AGN, NGC 7469, and Mrk 352, appear to be truncated at ∼35–125 and 50–135 r g , respectively. While our results show that the intrinsic FUV emission from the AGN is consistent with the standard disks, it is possible that UV continua may be affected by the presence of soft X-ray excess emission, X-ray reprocessing, and thermal Comptonization in the hot corona. Joint spectral modeling of simultaneously acquired UV/X-ray data may be necessary to further investigate the nature of accretion disks in AGN.


There is a growing realization of the need for highly integrated solutions enabled by new bi-directional data 'pipes' between design and manufacturing. Traditional EDA applications should be able to communicate and collaborate with yield analysis software. Simply adding such capabilities to existing EDA applications is not feasible. Thus, there is a need for an infrastructure that would enable such interaction in a standard way. We call this infrastructure the DFM Platform. In this article we present new approach to building such a platform. Brief descriptions of potential applications follow the platform architecture. "Via analysis" application includes test chips capabilities, critical area and critical parameter analysis to predict yield for a real design. The "DFM Cell Grading" module applies the concept of DFM to IP Libraries.


This paper studies the theory of RLC parallel-resonant circuit, including the voltage-current characteristics and the phase diagram of ideal RLC parallel circuit and actual RL-C parallel circuit, the relationship of capacitance and inductance reactive power, and the derivation and calculation of the quality factor Q. This paper also carries out simulation analysis on these two kinds of parallel-resonant circuits with Multisim software. The results not only easily verify the correctness of the theoretical analysis, but also quickly and accurately observe the amplitude frequency and phase frequency characteristic curve of parallel-resonant circuit, which simplifies the experimental operation, and makes up for the shortage of equipment.


Changes take place from the bronchial tree to the heart as a result of the altered oxygen-carbon dioxide exchange in the patient with emphysema. Each change requires adjustment by the patient in his way of life and presents a new challenge to the nurse. What happens to body structure and function and why are described here.


This work acquaints us with factors which have an influence on concentration of body cells in cow's milk. Moreover, it tells us about a relation between a quantity of body cells and a condition of a cow's mammary gland. In the article you can also see the algorithm of exposure of the main source of infection of the mammary glands in a herd.


Tardive dyskinesia (TD) is a type caused by the use of different medications. The pathogenesis of TD is associated with dopamine receptor blockade, gamma-aminobutyric acid depletion, cholinergic deficiency, oxidative stress, impaired synaptic plasticity, and neurotoxicity. TD most often occurs after taking metoclopramide, antipsychotics, antidepressants, calcium channel blockers, and other drugs. The review considers an adequate assessment of the potential risk of TD when the patient uses prescribed drugs, as well as the monitoring and correction of risk factors for TD, discontinuation or replacement of drugs that potentially cause TD, as well as its treatment.


Two of the most important thinkers of the twentieth century, Hannah Arendt and Theodor W. Adorno (whose thoughts tried to deal with the most extreme horror of that century, Ausch- witz) refused to communicate or even to take into consideration each other's works. This article attempts to bring them into dialogue from the point of view of what constituted the core of their work: thinking against the barbarity of the extermination camps - thinking and act- ing so that such barbarity is not repeated. After presenting the form in which both philosophers think the singularity of the genocide and the links with the historical and social processes that made it pos- sible, the article tries to analyze their underlying differences, which have to do with two irreconcilable theoretical approaches.


This study investigated the relationship between both receptive and expressive prosody and each of three reading outcomes: accuracy of reading aloud words, accuracy of reading aloud nonwords, and comprehension. Participants were 63 children aged 7 to 12 years. To assess prosody, we used the Profiling Elements of Prosody in Speech Communication (PEPS-C; Peppé & McCann, 2003). Results revealed that certain subtests of the PEPS-C predicted a substantial proportion of variance across reading outcomes, even after age and segmental phonological awareness have been considered. In fact, our findings suggest that the PEPS-C compares favourably with a well-established test of segmental phonological awareness, the Comprehensive Test of Phonological Processing (CTOPP; Wagner, Torgesen, & Rashotte, 1999), in terms of its power to predict variability in children's reading.


The effects of water flow under different light intensity on the growth of Microcystis aeruginosa were studied to elucidate the mechanism of water bloom.The experiment was conducted at a light intensity of 2 500 lx and 3 500 lx in a small perspex ring groove,which generated water flow under axenic condition and constant temperature and light.The results showed that the adaptation growth time of Microcystis aeruginosa increased,the exponent growth time was extended and the growth ratio was improved by water flow,which directly influenced the density of algae,and that the effects of water flow on the growth of Microcystis aeruginosa were related to light intensity.The light intensity at 2 500 lx was more conducive to the growth of Microcystis aeruginosa than that at 3 500 lx,the optimal water flow was 35 cm/s both for the light intensity of 2 500 lx and 3 500 lx.There were no significant differences among different water flow at the intensity of 2 500 lx.Therefore,there are not significant differences at 3 500 lx.The light intensity requirement was decreased and the efficiency was increased by water flow.


Objective To summarize the experience and method of endovascular treatment of unilateral A1 segment anterior communicating artery aneurysm with detachable coils.Methods Forty-eight patients with unilateral A1 anterior communicating artery aneurysm(23 males and 25 females,age ranged from 32 to 72 years with mean of 53.4,hospitalized in Xijing hospital from Jan.2009 to Apr.2010) were involved in present study.All of the aneurysms were measured with rotational digital subtraction angiography(RDSA) and image post-processing techniques,and they were embolized with Guglielmi detachable coils(GDCs).The patency of the parent arteries was monitored by catheterization in both carotid arteries in the process of treatment.Stent-assisted,balloon remodeling,microcatheter and microwire assisted techniques were used in the treatment of wide-necked aneurysm to keep patency of parent arteries.Cerebral angiography was performed in 38 cases 6 months after the operation to observe the patency of embolized aneurysms and anterior communicating arteries.Results Of the 48 cases,total occlusion was achieved in 39(81.3%),more than 90% occlusion was achieved in 6(12.5%),and 3(6.3%) with less than 90% occlusion;1 had hemorrhage during embolization,3 had anterior communicating artery occlusion,and 2 had contralateral internal carotid artery compensation after anterior communicating artery occlusion.No re-bleeding was found during the 6 months follow-up period.Cerebral angiography showed total occlusion of aneurysms and patency of anterior communicating arteries in 38 cases during re-examination.Conclusion The anterior communicating arteries should be kept patent in embolization treatment of the major unilateral blood supply anterior communicating artery aneurysms,and it is helpful to use microcatheter or microwire assisted techniques.


Developers often use a virtual platform to develop software before the hardware is available. For software optimization, it is important to profile the cache misses of applications in a realistic operating environment under the virtual platform. In the multicore era, it is hard to simulate the coherence cache miss in a high speed way. In this paper, we propose a hardware-accelerated architecture to simulate the cache misses of a multicore system. We implement the cache miss simulator over a virtual platform with FPGA. Users can profile their software as running over the multicore system. The evaluation shows the throughput achieves 65 MB of trace log per second, when FPGA works in 100 MHz and about 570,000 logic elements are occupied to simulate 4 sets of L1 cache and 1 set of L2 cache in the multicore system with 4 virtual CPUs. The system achieves 1.6 to 2 times of speedup, when comparing with the popular cache miss simulator, Dinero IV. Dinero does less work and does not support coherence cache misses in the multicore system. The evaluation result shows high advantage to speed up the cache miss simulation of the multicore system by the hardware-accelerated architecture as well as FPGA.


It is well known that the error for the observational data always exists and the elimination of the error is one of the main task for the survey data processing.To obtain the best estimated results,the error processing should obey the optimal estimated principle,such as the Least Square(LS) principle,but the optimal estimated principle determined should be based on the property and the distribution type of the observational error,so the distribution type of the observational error must be first established before the observational data processing.Traditionally,the distribution type of the error has been determined using the distribution collocation test method or [FK(W16?40ZQ] figure method by magnitude of errors,but it is difficult to obtain the specific distribution of the error,therefore,the suitable method to determine the error distribution must be found.To obtain the more reasonable method,the authors have proposed that the error distribution be collocated using the exponential distribution.The exponential distribution is a general distribution that can describe the arbitrary sequential distribution while the distribution parameter p is different.The property and the characteristic for the exponential distribution have been discussed in this paper.The analytical collocation method that determines the specific distribution of error has been proposed first by the authors.The main idea for the analytical collocation is that the known parameter A,C of the exponential distribution and the distribution parameter p are determined using the error interval value and the frequency for the special error interval,and the computational formulae have been derived in detail ,so that the explicit expression for the error distribution can be described by the parameter A,C of the exponential distribution and the distribution parameter p .Finally,the two numerical examples have been calculated and analyzed.The experiment results show that the analytical collocation method of the error distribution is very convenient and feasible,and the computational results are identical with conventional methods obtained by the references.

This paper introduced a strategy for parallel implementation of the FDTD algorithm used in COW (Cluster of Workstation) parallel computing system and PVM parallel environment. Because of the one-dimension space division, this method is relatively high efficient. Some computing examples were given to prove the feasibility and correctness of this method. This method provides a solve-scheme for the EM computation of electrical-large-size complex object and can be used in radiation, scattering and EMC analysis.


Background and aim: Bone marrow-derived mesenchymal stem cells (BM-MSCs) have been demonstrated to be an attractive therapeutic cell source for tissue regeneration and repair. However, it is difficult to obtain a large amount of differentiated cells in the transplanted site due to their low differentiation efficiency. In this study, therefore, we investigated the effects of differentiation-inducing factor-1 (DIF-1) on the BM-MSC differentiation efficacy into adipogenic or osteogenic lineages. Methods and results: BM-MSCs, which were obtained from Sprague-Dawley rats, were cultured until reaching 100% confluence in 12-well plates. Then, a growth medium was replaced the adipocyte or osteocyte differentiation medium, and the BM-MSCs were maintained for 2 to 3 weeks. In adipocyte differentiation assay, oil red-O positive area and adipocyte fatty acid-binding protein expression were significantly increased by DIF-1-treatment than control. On the other hand, in osteocyte differentiation assay, alizarin red-S positive area and runt-related transcription factor 2 expression were reduced by DIF-1-treatment. Further, the effects of DIF-1 on adipogenic and osteogenic differentiations were attenuated by treatment with glycogen synthase kinase-3 (GSK-3) inhibitor CHIR99021. Conclusion: It was revealed that DIF-1 promotes adipogenic differentiation of BM-MSCs through activation of GSK -3, whereas osteogenic differentiation was suppressed. These results indicate that DIF-1 may be useful for controlling the lineages of MSC differentiation.


The problem of prominences-corona relationship is relativelly old. Already in 1931 Lockyer [1] showed that there is a close relation between prominences distribution and the form of white-light corona. However, this problem is still debatable and poses a number of controversial questions. One of them is the question of the energy and mass exchange between prominences and the ambient corona. It is generally assumed that the mass balance exists between the corona and prominences, but unambiguous observational proofs for prominences-corona plasma exchange are very rare. There are little data [2-4], as well, that could be used to address the problem of slight plasma flows from prominences to the corona. In this contribution we give an observational evidence for slight disappearance of prominence plasma as it was found during the H-alpha observations with Lomnicky Stit coronograph and discuss possible explanations of this phenomenon.


The study looked at how women in Ogbadigbo local government, Benue State, participated in palm oil processing. The study relied on primary sources. Women's engagement in oil palm processing in Benue State and specifically in Ogbadibo Local Government Area was investigated using a public opinion survey research design. To gather relevant data from respondents in the study region, questionnaires were used. Data was collected from 134 respondents who worked in oil processing of the study area. The data was analyzed using descriptive statistics, gross margin, multiple regression modeling, and a Likert scale. Oil palm processing had a gross margin of $236135.78, and net processing income of $25367.50 per year. The significance between oil palm processing and palm oil production was tested using a paired sample t-test, which found that it was significant at P≤0.01 with a mean average of 28.10. 62. The results also showed that only 4% of respondents used current methods. Women also complained about insufficient funding and high maintenance costs as important challenges affecting oil palm processors, along with other concerns such as a lack of access to credit, insufficient storage, and a bad road network. Finally, the study advised that significant stages of processes such as fruit digestion and oil extraction be mechanized to relieve female processors of their labor. This will boost the number of women who work in the oil palm industry.


Gas pressure sintering (GPS) of reaction bonded silicon nitride (RBSN) was performed using Lu 2 O 3 -SiO 2 additive and the properties were compared with those of specimens prepared using high purity Si 3 N 4 powder. The relative density of RBSN and compacted Si 3 N 4 powder were 68.9 and 47.1%, and total linear shrinkage after sintering at 1900℃ were 14.8 and 42.9%, respectively. High nitrogen partial pressure (5MPa) was required during sintering at 1900℃ in order to prevent the decomposition of the nitride and to promote the formation of SiC. The relative density and 4-point bending strength of RBSN and Si3N4 powder compact were 97.7%, 954MPa and 98.2%, 792MPa, respectively, after sintering at 1900℃. The sintered RBSN also showed high fracture toughness of 9.2MPam 1/2 .


This article wants to contribute to the discussion. It can be said that New Public Management (NPM) was able to establish itself as the dominant paradigm in the higher education sector, even if the empirical determination is often difficult, since there are different forms of organizational implementation. At the same time, there is also disillusionment with what New Public Management cannot achieve, expressing clearly a "disenchantment" with NPM. Advancing networking processes are challenging NPM. This article attempts to show, which alternatives there exist in the governance of universities, or can be developed at least, for example the network governance. However, it is also being explored, which "mix", which pluralism, which combinations or re-combinations of governance in higher education would be possible and also innovative. So what comes after New Public Management?


The Indian economy has experienced a boom in outward FDI (OFDI) in 2006. The study aims at exploring the factors that drive the boom in OFDI of Indian firms.,The participation of a firm in OFDI is a two-stage process -first, the decision to internationalization and second, how much to invest. We employ a two-stage model to decompose the effects on the decision to internationalization from effects on how much to invest. The two-stage model has the advantage of allowing us to estimate separately the probability of internationalization by a firm – Pr(OFDI > 0) – and the expected volume of investment, E(OFDI|OFDI > 0). The former is estimated by the probit model and the latter is estimated by the ordinary least square model.,The study finds that prior experience and institutional advantage can strongly drive the internationalization of Indian multinationals. The study also examines the relative importance of two aspects of prior knowledge – length of prior knowledge and depth of prior knowledge on OFDI of Indian firms. The study finds that the depth of prior knowledge is a must influential driver of OFDI in comparison to its length.,The present study is a novel attempt to investigate, 'What drives the boom in OFDI from India?'

Stock price fluctuation has an important effect on consumption expenditure because people' s consumption is mostly determined by their prediction for future wealth. From this prospective, we can see that with the full play of the role featured by market system, the monetary policy should control the assets price when assets price fluctuation exceeds the range that material economy can stand. The new challenge of monetary policy faced mainly came from capital market. The monetary policy of the us Fedeial Reserve however, will attach more impurtance to stock marketing factors.


Annotation
Purpose. To reveal the shortcomings of the formation of the market of agricultural machinery and their impact on the economy of Ukraine.
Methods. Monographic, analytical, economic-mathematical, statistical.
Results. It is established that the introduction of "free prices" in Ukraine led to a violation of the principle of equivalence of exchange between industrial and agricultural products, became the main reason for the loss of effective demand of agricultural enterprises for material and technical resources, the decline of domestic engineering and, as a result, led to the monopolization of the agricultural machinery market foreign firms.
The main reason for the dominance of imported agricultural machinery in the domestic market of Ukraine was the low level of competitiveness of domestic counterparts, the lack of state regulatory policy and experience in the market environment.
The main actions of the bodies of state management of economic development of Ukraine, the implementation of which will contribute to the revival and development of domestic engineering for agriculture and strengthening its position in the domestic market of agricultural machinery.
Conclusions. The lack of state regulation of the domestic market of agricultural machinery has led to the loss of domestic engineering for Ukraine's agro-industrial complex, the dependence of the agricultural sector of Ukraine's economy on foreign firms, job losses in industry and reduced revenues to the state budget and social funds.
To revive the industry and increase sales of agricultural machinery of domestic production in domestic and foreign markets it is necessary:
• to provide favorable conditions for the creation of joint ventures with leading foreign companies for the production in Ukraine of competitive agricultural machinery with a gradual increase in its design share of components of domestic production;
• to provide state support to the priority areas of development of domestic mechanical engineering for the agro-industrial complex;
• to provide preferences for equipment of domestic production in the domestic market and to stimulate its export.
Keywords: market, agricultural machinery, government regulation, protectionism, competition, free price.


AEMOS is a simulator which aims to support the development of agent-based electronic markets capable of dealing with the natural semantic heterogeneity existent in this kind of environment. AEMOS simulates a marketplace which provides ontology matching services, enhanced with the exploitation of emergent social networks, enabling an efficient and transparent communication between agents, even when they use different ontologies. The system recommends possible alignments between the agents' ontologies, and lets them negotiate and decide which alignment should be used to translate the exchanged messages. In this paper we propose a new ontology alignment negotiation process, which promotes the reutilisation and combination of already existing alignments, as well as the involvement of business agents in the alignment composition process. With this new model, we aim to achieve a higher adequacy of the used alignments, as well as a more accurate and trustful evaluation of the alignments.

Measurements obtained as a function of incidence angle and polarization state of both fundamental and generated beams are reported.


Among the different labels applied to describe the present century, the most generally accepted one is "the age of anxiety". There are some obvious anxiety-creating situations in our day, such as wars, political and economical confusions, disasters, but also a less obvious but more deeper source of anxiety is the new technologies, more specifically the Computer Mediated Communication (CMC). Technology is beginning to mediate our social relationships, our self-identities and our social life. The position of communities and the self in CMC is showing the very character of anxiety. The body in the net is deterritorialised, displaced and dislocated. The anxiety platform is not looking to find an answer or solution to anxiety. But instead display the double character of anxiety. Anxiety has no proper place. So is the self in CMC. In the project , 2D graphics (Photoshop, Freehand), Dreamweaver, After Effects and Acid Pro is used.


An entropy‐based method is developed to estimate estuarine river discharge from surface velocity measurements. A two‐dimensional velocity profile based on the principle of maximum entropy is employed to express the mean velocity as a function of average surface velocity. The entropy‐based flow profile is parameterized by the location of maximum velocity in the channel and the shape of the velocity distribution. The entropy parameters are quantified over the tidal cycle to account for the unsteady nature of estuarine flow. The method was tested using experiments conducted at the Danshui River, the largest estuarine system in Taiwan. Surface velocities were measured using an Automated River‐Estuary Discharge Imaging System (AREDIS), and full‐channel velocity profiles were measured with a moving‐boat ADP survey. Entropy parameters were calibrated over the tidal cycle and linearly correlated with the average surface velocity to facilitate estimation from AREDIS measurements. The discharge calculated from average surface velocity and entropy relationships exhibits a 7.7% relative error compared to the ADP velocity profiles. The error nearly doubles when the mean values for entropy parameters are used instead of the variable parameters, indicating the importance of accounting for the unsteady nature of estuarine flows. Furthermore, the effects of measurement coverage area, types of entropy distribution, and wind‐induced drift current on the surface velocity‐based discharge measurement are evaluated and discussed. Overall, surface velocity measurements in conjunction with the entropy profiles well represent the flow in a complex estuarine environment to provide a reliable estimate of discharge.


It is shown that the Andrade-Guzman relation η = Aeb/T for the variation of viscosity with temperature is adequate for normal paraffins. Andrade's improved equation ην1/3 = Bec/vT gives less satisfactory results.


The metallurgical factors affecting HIC and SOHIC of high strength linepipe steel are investigated and the cracking resistance is correlated with diffusible hydrogen. Internal cracks were initiated at elongated MnS and TiNb(C,N) cluster regardless of the cracking mode. Increase in diffusible hydrogen content by cathodic charging or applying the external load makes the steel more susceptible to the cracking and it can imply that both of critical factors, inclusion clusters as well as diffusible hydrogen in the steel, should be carefully controlled to improve the cracking resistance.


Summary Background  Keloid disease (KD) is a common fibroproliferative disorder of unknown aetiology. T cells and macrophages are increased in KD and are thought to contribute to its pathogenesis. However, while a link between inflammation and fibrotic disorders is well known for other disorders, it remains undetermined in KD.

The loudspeaker is arranged in a containing space formed by the back casing and the circuit board, a sound producing face of the loudspeaker is arranged back to the back casing, and the side face of the mobile communication device is further provided with a sound producing hole. By means of the mode, a loudspeaker sound cavity module of the mobile communication device in the prior art is replaced, so that the mobile communication device can avoid increase of the thickness, and is simple in structure, convenient to assemble and low in cost.


Many arguments that show p to be enthymematic (in an argument for q) rely on claims like "if one did not believe that p, one would not have a reason for believing that q." Such arguments are susceptible to the neg-raising fallacy. We tend to interpret claims like "X does not believe that p" as statements of disbelief (X's belief that not-p) rather than as statements of withholding the belief that p. This article argues that there is a tendency to equivocate in arguments for the enthymematicity of arguments (e.g., Lewis Carroll's paradox, Hume's problem) as well as in arguments for the enthymematicity of action explanations (e.g., arguments for psychologism and for explanatory individualism). The article concludes with a warning, because the equivocation is often helpful in teaching and because neg-raising verbs include philosophically vital verbs: desire, want, intend, think, suppose, imagine, expect, feel, seem, appear.


In this paper, two-dimensional arrays of elements of an arbitrary finite field are examined, especially arrays having maximum-area matrices. We first define two-dimensional linear recurring arrays. In order to study the characteristics of two-dimensional linear recurring arrays, we also define two-dimensional linear cyclic codes. A systematic method of constructing two-dimensional linear recurring arrays having maximum-area matrices is given using the theory of two-dimensional cyclic codes. These arrays, here called \gamma \beta -arrays, may be said to be two-dimensional analogs of M -sequences. A \gamma \beta -array of area N_x \times N_y exists over GF(q) if and only if N_x N_y is equal to q^N _ 1 for some positive integer N . Many interesting characteristics of the \gamma \beta -array, such as the properties of its autocorrelation function and the properties of the characteristic arrays, are deduced and explained.


Let Ω be a compact convex domain in the plane. We prove that L2(Ω) has an orthogonal basis of exponentials if and only if Ω tiles the plane by translation. 0. Introduction Let Ω be a domain in R, i.e., Ω is a Lebesgue measurable subset of R with finite non-zero Lebesgue measure. We say that a set Λ ⊂ R is a spectrum of Ω if {e}λ∈Λ is an orthogonal basis of L(Ω). Fuglede Conjecture. ([Fug74]) A domain Ω admits a spectrum if and only if it is possible to tile R by a family of translates of Ω. If a tiling set or a spectrum set is assumed to be a lattice, then the Fuglede Conjecture follows easily by the Poisson summation formula. In general, this conjecture is nowhere near resolution, even in dimension one. However, there is some recent progress under an additional assumption that Ω is convex. In [IKP99], the authors prove that the ball does not admit a spectrum in any dimension greater than one. In [Kol99], Kolountzakis proves that a nonsymmetric convex body does not admit a spectrum. In [IKT00], the authors prove that any convex body in R, d > 1, with a smooth boundary, does not admit a spectrum. In two dimensions, the same conclusion holds if the boundary is piece-wise smooth and has at least one point of non-vanishing curvature. The main result of this paper is the following: Theorem 0.1. The Fuglede conjecture holds in the special case where Ω is a convex compact set in the plane. More precisely, Ω admits a spectrum if and only if Ω is either a quadrilateral or a hexagon. Our task is simplified by the following result due to Kolountzakis. See [Kol99]. Received May 1, 2001.

The Peroxisome proliferator-activated receptors (PPARs) play vital roles in regulating cellular differentiation, proliferation, and caspase-mediated cell death pathways. They are regarded as promising targets for anti-tumor drug development, particularly for multiple myeloma (MM) and different hematological malignancies. Several early section clinical trials are conducted to measure the clinical practicableness of PPAR agonists, notably PPARα and PPARγ agonists, against various cancers. A spread of studies has investigated PPARs expression in metabolic regulation. Furthermore, it has been suggested that careful designing of partial agonists for PPARs may show improvement with side effects and increase the therapeutic value. This review summarizes the organic chemistry and metabolic actions of PPARs, and the therapeutic potential of their agonists underneath clinical development. It investigates therapeutic agents for hematologic malignancies.


Modern economies have a high dynamics because of the rapid fluctuations of macroeconomic variables and parameters. Moreover, globalization emphasises the interdependencies among national economies, increasing their production capacities but, at the same time, making them more vulnerable to external perturbations. Shocks resulting from this turmoil can be absorbed depending on the degree of macromarket flexibility: goods market, labour market and money market. This flexibility becomes even more important for the member states of some optimal currency areas (OCA) because it considers both the mobility of production factors and the symmetry of business cycle transmission; i.e. the correlation of macroeconomic policies. The authors of this paper intend to analyse the situation of the internal mobility of workers as a basis for labour market flexibility.


Comprehensive studies on how vegetative ecosystems respond to fluctuations in precipitation and temperature patterns are of great necessity for environmental risk assessment and land-use evaluations. The present study examined the annual trends in vegetation greenness in Rwanda from 2000-2015 and assessed the relationship between these dynamics and climate factors by means of MODIS NDVI, air temperature, SOI and precipitation datasets. Mann Kendal trend test has been utilized to determine the direction and the rates of changes, while Spearman's rank correlation method has been used to determine the levels of associability between NDVI changes and climatic variables. The results indicate that approximately 11.9% of the country's vegetation has significantly improved (р < 0.05) from slight to significant improvement while 10.4% of the vegetative cover degraded from slight to severe degradation and an estimated 77.6% of the country's vegetation cover has remained relatively stable. Much of improvement has been detected in the lowlands of eastern province whereas much of degradation has been highlighted in the western highlands of the Congo Nile ridge and Kigali city. There was a weak correlation between NDVI anomalies and SOI anomalies (rs = 0.36) while near surface air temperature was moderately correlated (rs = 0.47) with changes in Mean NDVI. Precipitation was more significantly associated (r = 0.84) with changes in vegetation health in low plains of Eastern Province (Nyagatare District in particular) than in the high altitude regions of the Congo Nile ridge. A strong positive correlation with precipitation was found in rain fed croplands; mosaic vegetation; mosaic forest or shrubland, herbaceous vegetation/grass-land savannah and sparse vegetation. Identification of degradation hotspots could significantly help the government and local authorities galvanize efforts and foster results driven policies of environmental protection and regeneration countrywide.


Objective—To identify extracellular proteoglycans produced by canine melanoma cell lines and analyze the effect of transforming growth factor-β1 (TGF-β1), insulin-like growth factor-I (IGF-I), and hepatocyte growth factor (HGF) on these proteoglycans. Sample Population—3 canine melanoma cell lines (ie, CML-1, CML-6M, and CML-10c2). Procedure—Extracellular proteoglycans were analyzed by use of metabolic labeling and western immunoblot analysis. The effect of TGF-β1 on cell proliferation was determined by incorporation of 5- bromo-2'-deoxyuridine. Results—The CML-1 and CML-6M melanoma cell lines produced 2 main extracellular proteoglycans. One of them was identified as versican, a proteoglycan found in undifferentiated human melanoma cell lines. The CML-10c2 cells produced a small amount of extracellular proteoglycans. Addition of TGF-β1 (1.25 to 6.25 ng/ml) increased the release of sulfated proteoglycans into the medium. The TGF-β1 had mainly a posttranslational effect, because it increased the molecular m...


For some time we were intrigued by an unknown compound appearing on amino acidschromatograms of urine from patients receiving a lactose free evaporated milk in which lactose had been replaced by glucose. The unknown substance was isolated by ionexchange chromatography and identified as Nε-/1-deoxyfructosyl/-lysine/εdFrclys/ by chemical degradation, elemental analysis, field desorption mass spectrometry, and chromatographic comparison with the synthetic reference compound. εdFrcLys, an Amadori product, was bound to the protein of this particular milk in a concentration of about 2 g per 100 g milk protein. It has practically no nutritional value since about 16% were excreted as intact dFrcLys in urine and about 55 % in faeces.


The gist of the ideas presented here was formulated while trying to bridge the gap between a simple physical conception of the world and the global philosophy of life of A. Manning. Some ideas about Energy Consumption and Coding were further developed in a group discussion with Sophie Heinrich, Mael Montevil, Arnaud Pocheville and Livio Riboli-Sasco, whom it is our pleasure to thank here. 1. SHAPE IS THE ESSENCE OF LIVING SYSTEMS When Biology first appeared, long before its recent mutation into Molecular Biology, it was occupied with the description of the shapes of the different living beings. Shapes are difficult to describe. They are most easily transmitted by drawings, on which names can be ascribed, helping to outline the elements of simple shapes. Similar elements can be recognized in different living life forms and used to group them, with both their similarities (same elements) and differences (element shaped slightly different). Thus, it is easy to make abstract categories such as leaf, even though leaves differs greatly in the details of their shapes, and group similar individuals (organisms) by species, family, genus, etc. The fact that these distinctions are meaningful comes from the information that shapes reveal a deep organization of living beings (usually associated with functions) that are shared throughout the living world. Biology eventually became focused on the transmission of shapes through generations (genetics) and the explanation of the similarities of shapes by a slow variation (evolution). In so doing, the tendency is to forget the shapes as entities, in and of themselves. 2. THE DIFFERENCE BETWEEN LIVING AND INERT OBJECTS Inert object also have shapes. Crystals can be recognized by their characteristic shapes and colours. As first notice by Botanist L. Bravais, who became a crystallographer, shapes reveal internal organization at an atomic level. The main difference lies, not in the existence of characteristic shapes, but in the dynamics. Inert objects are, by definition, inert and do not change in time. If they do change, it is only by the aggression of being chemically and mechanically attacked or melted by the outside environment. Because crystals have a passive system of defence the pieces that comprise them remain unchanged over time. As a result some crystals can give us the age of the earths formation. Similarly, living systems succeed in keeping their shape, but they do so in a completely different way. They preserve their organization by constantly demolishing and recreating, as the elements are changing regularly. For instance, blood cells are changed weekly Article available at http://www.origins-and-evolution.org or http://dx.doi.org/10.1051/orvie/2009005


The embodiment of the invention discloses a data transmission method and apparatus in device-to-device (D2D) communication, relating to the field of wireless communication, used for solving the problem how each D2D terminal in the same D2D communication group utilizes D2D communication resource for carrying out data transceiver. In the scheme, a network side apparatus receives resource occupying request transmitted by at least one D2D terminal in the same D2D communication group, determines the D2D communication resource corresponding to the D2D communication group; determines a resource position in the D2D communication resource of the transmission resource of each D2D terminal in the D2D communication group according to the received resource occupying request; informs the resource position of the transmission resource of each D2D terminal to the corresponding D2D terminal, and the D2D terminal carries out data transmission on the transmission resource of the D2D terminal according to the information. Hence the scheme solves the problem how each D2D terminal in the same D2D communication group utilizes D2D communication resource for carrying out data transceiver.


The effects of biochar addition in improving soil physical properties are not clearly understood in mining tailings. The objective of this study was to determine the effects of three different types of biochars, in addition to marble mud (MM) and their mixtures, on the structural stability and water retention of mine wastes in Cartagena, Spain. Biochars were produced at 500 °C from pig manure (PM), cotton (Gossipium hirsutum L.) crop residues (CR) and municipal solid waste (MSW). Biochars were added to the mine waste (MW) along with MM and a control (no amendments added). These mixtures were incubated in cores for 90 days (25 °C). PM and CR mixed with MM decreased soil bulk density (from 0 · 98 g cm‐3 to 0 · 89 and 0 · 84 g cm−3, respectively). Amendments had no significant effect on total porosity whereas they increased gas diffusion by 100%, except for MSW. MM improved the plant available water from 0 · 59 to 2 · 56 cm as its combination with biochars, extremely relevant in water scarce climates. The micropores were likely replaced by mesopores when application of PM, CR, MM, and biochars + MM and they improved water retention. Total carbon (TC) and total nitrogen (TN) increased by using biochars and MM and no significant effects were assessed on aggregates. In general, MM mixed with PM and CR derived biochar improved the structural stability and exhibited a strong impact in reclaiming physical quality on mine tailings.

The outbreak of pandemic influenza A (H1N1) around the world has caused significant economic loss and human death. It is a urgent challenge to improve our response to pandemic influenza A (H1N1) outbreaks, and avoid its epidemic. Computer simulation is a pragmatic and effective methodology for analyses of influenza A (H1N1). A spatially explicit epidemiological simulation system is proposed to study the outbreak and transmission of influenza A (H1N1) in mainland China. In this system, a SEIR epidemic model is developed, and traffic between provinces and four kinds of prevention and control measures are considered. Additionally, Geographic Information System (GIS) tool is incorporated in the system to provide friendly interface for model development, epidemic simulation, and temporal-spatial analysis. Preliminary experimental results have shown the effectiveness of the system.


A combined caliper and tri-axial MFL in-line inspection (ILI) reported a bottom side 2.7%OD dent associated with 76% metal loss. The reported dent depth is well below the 6% limit while strain analysis of this ILI dent profile showed a maximum equivalent strain of 17.4%, which exceeds the 6% strain limit for gas pipeline. Due to the high dent strain level, the raw signals of metal loss were revisited, which indicated this associated metal loss appears to be a crack rather than corrosion. In-field investigation revealed that this dent is indeed associated with branched cracks both at internal and external pipe surface but no leak was detected.The primary objective of this case study is to determine the cause for cracking in the dent. As part of this study, detailed investigation was performed including LaserScan based strain analysis, lab pressure-cycle testing and fracture surface examination. An attempt was made to quantify the plastic strain damage of this dent and its susceptibility to cracking using the existing plastic damage models, namely, ductile failure damage indicator (DFDI), strain limit damage (SLD) and minimum elongation limit criterion. The investigation showed that the internal cracks were formed at the time of indentation while the external cracks formed by spring-back (elastic rebounding) due to the removal of rock constraint. Full size fatigue testing of this cracked dent showed leak failure modes rather than rupture. In this paper, the approach, results and the findings are summarized and discussed.© 2012 ASME


This study was conducted to identify attitudes of diab etic patients towards compliance to treatment and to measure their compliance to treatment. A cross sectional study was conducted in King Abdul Aziz Specialized Hospital; Taif; KSA during June – October 2013. Convenient method of sampling was adopted. Al l adult (> 18 years) diabetic males were recruited. Data was collected through face - to - face interview method using structure questionnaire. Data was processed using the software Statistical Package for Social Science (SPPS). A total of 378 patients was rec ruited, of them 219(57.9 %) aged 40 - 65 years. Patie nts who were living in the town were 307(81.2 %) and more than one third had either college or university education. Overall 185(48.9 %) of the patients had positive attitude s towards compliance to treatme nt, while 193(51.1 %) had negative ones. Significant associations were documented between patients' attitude towards compliance and both patient's marital status and employment status (* P = 0.015), (* P = 0.020) respectively. The prevalence of non adherence was found to be 80.7 % (n = 305). Out of the patients who had positive attitudes towards compliance 145(78.54 %) were non - adherent, and 40(21.6 %) were adherent. In contrast, of the patients who had negative attitudes towards compliance 160(82.9 %) were n on - adherent and 33(17.1 %) were adherent, ( P = 0.226). In conclusion in this setting non - adherence to treatment was prevalent. Continuous patient educational interventions tailored to individual patient are needed to improve both patients' attitude s and ad herence to treatment.


Within the context of the nascent e-Science infrastructure in Venezuela, we describe several web-based scientic applications developed at the Centro Nacional de C alculo Cient


The use of eco-friendly methods in controlling pest and diseases has become an increasing concern in production system in many economically important crops, including ornamentals. The application of plant extract that has an insecticidal effect is considered as one promising alternative in reducing the negative effects of synthetic pesticides. The research was conducted to assess selected plant extracts in several concentrations against leaf miner (Lyriomyza spp.) in chrysanthemum. The experiment was carried out from January to December 2017 under plastic house conditions at the Indonesian Ornamental Crops Research Institute (IOCRI). The extracted organ of insecticidal plants regularly sprayed into chrysanthemum plants and compared with water as the controls. The results showed that the application of insecticidal plants extracts reduced attack intensity and incidence from water treatment (control). Certain treatment combinations, Chinese mahogany leaf extract at the concentration of 0.25%, C. pyrethrum petal 0.15 and 0.30%, and chinaberry leaf at 0.3, 0.35% even had 0.9-3.13% lesser attack incidences than commercial botanical insecticide Neem Plus. The respected treatments also supressed more than 62% leaf miner attacks and induced the increase of marketable flowers.


The paper proposes a new complex network with time-delay according to the idea of quorum sensing.The feature of the network is no coupling between the nodes,but by the sense of an external signal and each node,time-delay exists in the sensing process.It is proved right based on Lyapunov stability theory that,when the system parameters satisfy certain conditions,nodes can achieve complete synchronization by controlling the quorum sensing strength.The result of numerical simulation shows the nodes can achieve synchronization at periodic solutions,and complexity of the periodic solution is different with the different quorum sensing strength.


Dueholm S, Rubinstein E, Reipurth G. Preparation for elective colorectal surgery: a randomized, blinded comparison between oral colonic lavage and whole-gut irrigation. Dis Colon Rectum 1987;50:360-364. An oral colonic lavage solution containing sodium sulfate and polyethylene glycol was compared with whole-gut irrigation using saline via a nasogastric tube in a randomized blinded study of 34 consecutive well-matched patients undergoing elective colorectal surgery. Both methods were safe and rapid. Patients receiving oral colonic lavage, however, had significantly less (P < 0.05) water retention, overall distress, cramps, and other complaints. No significant differences were found with regard to fullness, nausea, and rectal discomfort. The bowel deausings were equally adequate, and most patients achieved a good-to-excellent preparation. Surgical complications appeared not to be related to the preparation used, and wound sepsis were equally frequent. Oral colonic lavage proved to be the most attractive preoperative cleansing method.

Nowadays, Concurrent Engineering (CE) is becoming more important as companies compete in the worldwide market. Reduced time in product development process, higher product quality, lower cost in manufacturing process and fulfilment of customers' requirements are the key factors to determine the success of a company. To produce excellent products, the concept of Concurrent Engineering must be implemented. Concurrent Engineering is a systematic approach which can be achieved when all design activities are integrated and executed in a parallel manner. The CE approach has radically changed the method used in product development process in many companies. Thus, this paper reviews the basic principles and tools of Concurrent Engineering and discusses how to employ them. Similarly, to ensure a product development process in the CE environment to run smoothly and efficiently, some modifications of the existing product development processes are proposed; these should start from market investigation to detail design.

An upcoming boom in the use of cogeneration and other independent and alternative sources of energy is already creating major benefits for users, energy service companies, and the nation's utilities that will increase substantially over the next decade. Energy-services companies are now positioning themselves to take advantage of rapidly accelerating growth in the cogeneration business and this major window of opportunity, due in part to both governmental support and basic economic forces. These forces have been instrumental in driving many industrial, commercial, and military users toward cogeneration at a rapidly increasing rate to control their costs and assure future energy supplies. Growth is also being accelerated by major equipment manufacturers, consultants, and contractors willing to enter the energy-services industry to try to stimulate the use of their products and services in this important new market.


3D Printing is a widely used manufacturing method whose processing speed is very fast. This method is suitable for a variety of complex geometric structure in many application fields, and supports a variety of material types. At present, 3D printer is not only used in manufacturing, but also began to be used in education, architecture, design industries and so on. However, at home, there are less 3D printer manufacturers most of which are universities and research institutions, and price of 3D printer is relatively expensive. After analyzing how 3D printer works, this paper built 3D model of 3D printer and achieved printing simulation of STL model using two PCs basing on VC++ and ACIS/HOOPS. Two PCs communicate with each other through serial ports. One PC serves as host computer, on which controlling software runs, is responsible for loading the STL model, data processing, generating and sending printing commands and data to 3D printer. The other serves as slave computer, on which 3D printer simulation software runs, is responsible for receiving motion commands to control 3D printer to finish corresponding movements. Real-time rendering of 3D printer and human-computer interaction are achieved using rendering engine HOOPS. This method proposed in this paper adopted semi-physical virtual prototype technology, used real STL model to control virtual 3D printer to simulate 3D printing. It has no need for real 3D printer and is of important practical significance for debugging software of 3D printer.

It is well known that pepsinogen (PGs), as an important precursor of pepsin performing digestive function, has a good correlation with the occurrence and development of gastric cancer and it is also known that ectopic PGs expression is related to the prognosis of some cancers. However, the panoramic picture of pepsinogen gene family in human cancer is not clear. This study focused on elucidating the expression profile, activated pathway, immune cells infiltration, mutation, and copy number variation of PGs and their potential role in human cancer.


Many challenges must be faced by thr GOI in developing the program, nowadays the Govemment of lndonesia (G01) through Early Childhood Education (ECE) Department has been enhancing early childhood education programs for 0 to 8 year old children. The major challenges are children access to early childhood education services and quality of early childhood education programs. Considering the challenges, The United States Agency for Intemational Development (USAID) in partnership with Indonesia's Ministry of National Education is currently implementing a small scale interactive audio instruction (1AI) pilot program targeting 5-6 year olds and their teachers in seven provinces. The program can simultaneously lead acfivities to kindergarten children and teachers as well as train the teachers, who don't have early childhood education background, and how to create high qualityactivities for children. Because of its' simple technology, the program can be applied in various Indonesia district condition, This paper explores the potential role a simple technology can play in assisting the government meet its early childhood education goals and discusses whether something as commonplace as a CD player or radio, when coupled with a proven education methodology, could present a cost effective way to achieving quality at scale.
