PurposeThe purpose of this paper is to analyze the hedging capacity of Bitcoin in relation to the S&P 500 index during the COVID-19 pandemic.Design/methodology/approachIn order to investigate the hedging features of Bitcoin in relation to the S&P 500 index during the COVID-19 pandemic, the authors use the Granger causality applied on a daily sample of observations ranging from January 1st, 2019 to December 31st, 2020. As robustness checks, the authors use autoregressive models to test the validity of the findings.FindingsUsing time series of daily data from 1st January 2019 to 31st December 2020, the results show that Bitcoin is not considered as a safe haven because it moves at the same pace as the S&P 500. As a robustness check, the authors use the exponential GARCH model and confirm our previous findings. Overall, the study contributes to the debate on both COVID-19's impact on financial systems and the hypothesis of Bitcoin being a safe haven during extreme global crises.Originality/valueThe study contributes to the debate on both COVID-19's impact on financial systems and the hypothesis of Bitcoin being a safe haven during extreme global crises.


Abstract Abstract: In this research, the glasses were made with composition (70-x) P2O5 - 10Bi2O3 - 10Na2O - 10Gd2O3 - xSm2O3 (with x = 0; 0.05; 0,1; 0, 5; 1.0; 3.0 mol%). Molar volume, polar radius and inter nuclear distance decreases with increasing concentration Sm3+ in phosphate glass. However the refractive index, susceptibility of the oxide ion, polarizability (α) and reflection loss does not change in value. XRD diffraction shows that the patterns shape of the glasses spectrum are found no sharp peaks along the diffraction angle observation area (2θ). This shows that the concentration of Sm3+ ions does not affect the diffraction pattern of Sm: phosphate glass. The strongest FTIR spectrum is archieved PBNaG: Sm5 galss with wavenumber 871 cm−1.


This paper introduces the theories of Lagrange interpolation and Chebyshev fitting,describes the sliding algorithm of interpolation and fitting.Then the accuracy of interpolation and fitting is analysed by examples,and the research on the influences of polynomial ranks and knots number is also done in the paper.The results showed that with a certain range,the higher the polynomial ranks,the more accurate the interpolation and fitting.The fitting accuracy achieves highest when the knots number of Chebyshev polynomial equals to the polynomial ranks plus one.In this case,the fitting results has a high consistency with Lagrange interpolation results.


Pulmonary rehabilitation (PR) is an evidence-based intervention to manage symptoms related to chronic obstructive respiratory diseases (CORD). Paradoxically, only few people with CORD actually engage in, and of those, up to a third would do not complete the program. Additionally, some of those who complete the program would not achieve worthwhile benefits. Therefore, the main challenge for the next decades is to offer PR to as many people (that would potentially benefit from it) as possible. This raises question about factors influencing participation, completion and responsiveness to PR programs. Among these factors, urinary incontinence is highly prevalent among people with CORD (much more than in the general population) and may worsen during PR exercise sessions. Paradoxically, urinary incontinence is poorly explored in routine and scarcely assessed in research, and none of the actual guidelines about PR mention it. However, its potential influence on engagement, completion and response to PR is of real concern. Therefore, the aim of this perspective is to describe the mechanisms of UI, particularly in the context of CORD, as well as to highlight its prevalence among people with CORD, their burden, and how it could affect a PR approach based on sustained and regular physical activity.


【To figure out wheher the tribological properties of a hras-coating layer can be imporved by ion implantatio, TiN-coated SKD 11 61 were implanted with nitrogen ion and their wear peoperties were examined systematically. The amount of nitrgen ione implanted on the coating layer was $2 \times 10^{15},\;10^{16},\;10^{17},\;and\;10^{18}\;ions/\textrm{cm}^2$ , respectively. X-ray diffraction revealed theintensity of the peaks belong TiN tended to increase as the ion dose increased, which implied that the implantation promoted the formation of TiN in the coated later. Howeverthe hardensity of the specimens increased then decreased again as the ion dose increased, resulting in a obvious drop of the hardness for the ion does of $2 \times 10^{18}\;ions/\textrm{cm}^2 $ . While the adhesion of the coated layer of SKD 61 was excllent regrdless of the implatation, the adhesion of the later of SKD 11 was apparently improved by the implantation. The overall wear properties of SKD 11 was better than that of SKD 61, and the best result was yielded at the ion dose of $2 \times 10^{15}\;ions/\textrm{cm}^2$ .】

Abstract The Pseudomonas fluorescens strain HP72 used as biocontrol agent was isolated from the roots of creeping bentgrass on brown patch-suppressive soil. This strain can suppress brown patch disease caused by Rhizoctonia solani. The analysis of secondary metabolites from strain HP72 revealed that it produced known antifungal compounds, 2,4-diacetylphloroglucinol (2,4-DA-PG), HCN, and a fluorescent siderophore. In the present study, the Tn5inserted mutants of strain HP72, which did not show any antifungal activity, were selected. None of the mutants produced 2,4-DA-PG but they produced a fluorescent siderophore, while some strains produced HCN. Therefore, it is suggested that 2,4-DA-PG plays a major role in the biological control of brown patch disease caused by R. solani. In the genomic region where Tn5 was inserted, two open reading frames (ORFs A and B), which are not included in the 2,4-DAPG gene cluster of HP72, were detected. It was demonstrated that ORFs A and flare involved in the regulation of 2,4-DAPG biosynthesis.


Whiplash injury remains a profoundly controversial topic. The UK has been dubbed "the whiplash capital of the world", with a whiplash claim made every minute. Jack Straw MP has described whiplash injury as an "artificially contrived injury which can't be proven." In the UK, 75% of personal injury claims following road traffic accidents (RTA) are for whiplash injuries while, in France, this figure is a mere 3% (Chappuis & Soltermann 2008). There also exist wide variations between countries in the cost of claims; for instance the average payout in Switzerland for whiplash jury is in the region of €35,000 (£30,000) compared to the equivalent of around €3,000 (£2,500) in the UK.

Non-contiguous word sequences are widely known to be important in modelling natural language. However they not explicitly encoded in common text representations. In this work we propose a model for text processing using string kernels, capable of flexibly representing non-contiguous sequences. Specifically, we derive a vectorised version of the string kernel algorithm and their gradients, allowing efficient hyperparameter optimisation as part of a Gaussian Process framework. Experiments on synthetic data and text regression for emotion analysis show the promise of this technique.

Despite the discovery of tubercle bacillus more than a hundred years ago, and all the advances made in our knowledge of the disease since then, tuberculosis still remains one of the major health problems facing mankind, particularly in developing countries. From a global perspective, many laboratories use the same methods today that were in use nearly half a century ago: conventional stains such as Ziehl-Neelsen or Kinyoun for staining sputum smears, given rise to low case detection rate. This necessitated this study-to compare the iLED fluorescence with the ZeihlNeelsen Techniques. We randomly collected Seven hundred and sixty eight (768) sputum samples from three hundred and eighty four TB suspect patients aged 15-65years,their smears were prepared ,fixed and stained according to laid down procedures; results showed that two hundred and seven were positive for acid fast bacilli (AFB) with a percentage positivity rate of 26.95% , from smears stained with Auramine-O and examined with the iLED Fluorescence microscope ; while seventy five were positive with percentage positivity rate of 9.77 % with smears stained with the Ziehl-Neelsen staining technique. The yield achieved with fluorescence microscopy exceeded the yield achieved with light microscopy "26.95% compared with 9.77%", but the difference was not statistically significant (t=1.76; P>0.05). The case detection rate was 17.18%. This clearly shows the superiority of fluorescence microscopy over the conventional light microscopy for the diagnosis of tuberculosis.


A hundred years ago, two British expeditions measured the deflection of starlight by the Sun's gravitational field, confirming the prediction made by Einstein's General Theory of Relativity. One hundred years later many physicists around the world are involved in studying the consequences and use as a research tool, of the deflection of light by gravitational fields, a discipline that today receives the generic name of Gravitational Lensing. The present review aims to commemorate the centenary of Einstein's Eclipse expeditions by presenting a historical perspective of the development and milestones on gravitational light bending, covering from early XIX century speculations, to its current use as an important research tool in astronomy and cosmology.


The optimal combination of drug therapy and physical factors increases the effectiveness of treatment and medical rehabilitation of patients. It is regrettable that the search for methods to improve the individual dosing of the energies used with an approximation to the cellular level of dynamism (constant correction of the parameters of the physical factors used during the entire period of treatment) and complex (in the presence of several diseases) treatment are clearly insufficient today. Perhaps such a search is difficult due to the current lack of a general theory of physiotherapy and the imperfection of the classification of physical factors. In this regard, there was a need to develop principles and methods for a comprehensive study of the effect of physical methods in clinical settings, and the requirements for testing new devices for physiotherapy sharply increased. The author of this direction was an outstanding scientist Vladimir Sergeevich Ulashchik. In his opinion, the creation of a general theory of physiotherapy is one of the promising tasks of scientific physiotherapy.


Minimax designs provide a uniform coverage of a design space $\mathcal{X} \subseteq \mathbb{R}^p$ by minimizing the maximum distance from any point in this space to its nearest design point. Although minimax designs have many useful applications, e.g., for optimal sensor allocation or as space-filling designs for computer experiments, there has been little work in developing algorithms for generating these designs. In this paper, a new clustering-based method is presented for computing minimax designs on any convex and bounded design region. The computation time of this algorithm scales linearly in dimensionality $p$, meaning our method can generate minimax designs efficiently for high-dimensional regions. Simulation studies and a real-world example show that the proposed algorithm provides improved minimax performance over existing methods on a variety of design regions. Finally, we introduce a new type of experimental design called a minimax projection design, and show that this proposed design provides better minimax performance on projected subspaces of $\mathcal{X}$ compared to existing designs.


No THOUGHTFUL READER of Johnson has ever doubted the truth of Boswell's remark that "the history of his mind as to religion is an important article."' Johnson himself admitted to the significant role it played in his life and asserted just six months before he died that "the highest honour and most common pleasure this life can afford, must be obtained by passing it with attention fixed upon Eternity."2 All of the major biographical studies published shortly after his death, furthermore, support Boswell's claim.3 They make clear that Johnson was a deeply religious man who accepted without question the existence of God, who affirmed his faith in the principal truths of Christianity, who was an ardent Church-of-England man, and who sought throughout his life to render himself worthy of salvation. Of these contemporary accounts, Boswell has offered the best general account of Johnson's religious beliefs in his summary of Johnson's character at the end of the Life.4 And in the nearly two hundred years since Johnson's death, there has been almost no


Effects of single intraperitineal adiministration of non radioactive zirconium citrate on femur uptake and urina excretion of either simultaneously injected intravenous Ce/sup 144/, Pu/sup 239/(VI) or Y/sup 90/ were compared in rats during the initial post-injection hour. Zirconium treatment was associated with increased plasma disappearance of Pu/sup 239/. parisons in control and treated animals indicate that zirconium citrate treatment has no effect to alter rates femur deposition for the early time interval studied, that it enhances urinary excretion of Ce/sup 144/ and Y/sup 90/, with only a very small effect on Pu /sup 239/ excretion.

Anti‐liver cytosol type 1 (LC1) autoantibody is detected in 30% of sera from patients with type 2 autoimmune hepatitis (AIH), and is the only circulating autoantibody in 10% of cases. Human formiminotransferase cyclodeaminase (FTCD) has been shown to be the specific liver antigen recognized by anti‐LC1 autoantibodies. The aim of this study was to identify the dominant epitope on human FTCD and to analyze antigenic‐site sequences for clues on the development of AIH. Recombinant proteins and peptides covering the entire cDNA of human FTCD were tested against anti‐LC1 autoantibodies. Conformational epitopes were found throughout the protein but linear epitopes were found exclusively in the C‐terminal 146 amino acids. Two groups of sera with different reactivities were found: 69%of the sera recognized two specific linear epitopes at positions 428–434 (NTPEEKD) and 440–447 (LQEGLRRA) of human FTCD; others reacted only with a discontinuous epitope between the amino acids at position 395 and 528. FTCD autoantibody production is thus a polyclonal‐antigen‐driven B cell response. Autoantibodies against conformational or discontinuous epitopes were found in all patients and two‐thirds also recognized linear epitopes on human FTCD.


There is still a lot to be discovered and learned regarding Non-Ionizing Radiation (NIR) radiofrequency (RF), particularly with reference to NIR long-term effects on human health and the environment or ecosystem.


The first glycoconjugate vaccine for use in humans, a Haemophilus influenzaetype b (Hib) conjugate, was licensed in the USA in 1987 and shortly thereafter was introduced into the US infant immunization schedule. The success of the Hib conjugate vaccines in reducing the incidence of invasive Hib disease in childhood [1–3] has accelerated the development of conjugate vaccines designed to prevent infection by other encapsulated bacteria. The imperative driving the development of such vaccines has been the need to find a vaccine formulation that renders bacterial capsular polysaccharides immunogenic in those most at risk of infection. Pathogens such asNeisseria meningitidisserogroup C, Streptococcus pneumoniaend Hib are all major causes of childhood meningitis as well as other infection syndromes and have in common polysaccharide capsules (although of different structure) that act both as virulence determinants and targets for protective antibody. The importance of these pathogens in the young can partly be explained by the poor immunogenicity of some polysaccharides in this age group and the consequent inability of infants and young children to mount protective antibody responses. Vaccines containing Hib or pneumococcal capsular polysaccharides alone have thus failed to consistently protect this high risk group from infection [4,5].


Using empirical data, a map of composition versus magnetic properties was developed to design Ni-Mn-In magnetic shape-memory alloys. By the aid of this composition map, five alloys with desired properties were designed. A linear composition dependence of martensitic transformation temperature (Tm) and alloy was revealed. A transformation from austenite to martensite could be achieved at an electron concentration of ∼7.9. As such, a series of magnetic shape-memory alloys, which work at different conditions, can be designated under the guidance of a series of contour maps derived from Tm and thermal hysteresis.


Carbon emissions are closely linked to a company's production activities. The amount of carbon allowances a company holds determines its carbon emissions. Changes in carbon prices interact with firms' production activities, while changes in exchange rates and interest rates have a direct impact on firms' production structure, willingness to produce and scale of production. Under the existing literature, most scholars have selected only one market to be used to study its influence on the carbon market. In this paper, the exchange rate market and the interest rate market are selected for the study of the impact of both on the carbon market, using the following empirical analysis methods: DCC-GARCH, TVP-VAR and GA-BP neural network. The empirical results show that interest rates are positively linked to carbon prices, while exchange rates are more negatively linked to carbon prices; exchange rates are less affected by macro factors and external shocks, while interest rates are the opposite and very sensitive to macro shocks; under the training and simulation of the neural network, carbon prices can fluctuate drastically under the combined influence of exchange rate and interest rate movements, which can provide appropriate early warning of future price fluctuations in carbon trading. This shows that adjustments to exchange rates and interest rates need to be treated with caution, and appropriate adjustments should be made to keep carbon prices stable; the government should build a mechanism to transform the green development of enterprises, pushing them to save energy and reduce emissions to achieve low-carbon transformational development; the government should not only introduce policies to support low-carbon enterprises, but also improve the national carbon market laws and regulations and price regulation mechanisms.


Ovarian infiltration in pediatric non‐Hodgkin lymphoma (NHL) at presentation is rare and information on outcome is scarce and mainly based on case reports and small series.


Promoter hypermethylation of tumor suppressor genes is one of the mechanisms of epigenetic regulation disturbance of gene expression and is often observed in different cancer types. The profile of mutational and epigenetic changes characterizes a malignant potential of a tumor, as well as its ability to invade and metastasize.The aim of the study was to determine a prognostic value of p16, p14ARF and TIMP3 gene methylation in the group of 158 bladder cancer patients. Epigenetic changes in these genes were observed with a frequency of 11.4, 0 and 10.8 %, respectively, and did not depend on clinic-morphological characteristics.A statistically significant association of p16 and TIMP3 abnormal methylation with smoking was found, indicating a possible influence of tobacco smoke carcinogens on the occurrence of these epigenetic changes. In the multivariate Cox regression analysis, p16 promoter hypermethylation was an independent predictor for bladder cancer progression (HR 6.84; 95 % CI 1.6–29.9; р = 0.011).The use of the data on the p16 methylation status may improve the accuracy of prognosis of the bladder cancer clinical course and the selection of appropriate treatment strategy.

Lead patenting process is the most efficient way to transform hot rolled steel wire rod of different chemical composition into fine pearlitic steel. However, the optimization of various parameters of lead patenting process is critical to achieve high efficiency of transformation process in mass production of hypereutectoid steel wires. The experiment was conducted to find out the optimum range of austenitic temperature, lead bath temperature and phase transformation time. The effect of carbon percentage, size of steel wire rod and drawn strain prior-to- patenting on mechanical properties are also observed through various experiments and evaluated.


Several time-recursive least squares algorithms have been developed in recent years. In this paper a geometrical formalism is defined which utilizes a nested family of metric spaces indexed by the data time interval. This approach leads to a simplified derivation of the so-called recursive least squares lattice algorithms (recursive in time and order). In particular, it is found that the resulting structure provides a single framework which encompasses an entire family of fairly complex algorithms, as well as providing geometrical insight into their behavior.


In 1998, Zalesskii proposed to classify all instances of irreducible characters of quasi‐simple groups which are of prime power degree. In joint work, Malle and Zalesskii then dealt with all quasi‐simple groups with the exception of the alternating groups and their double covers [5]. In an earlier article [1] we have classified all the irreducible characters of Sn of prime power degree and have deduced from this also the corresponding classification for the alternating groups. In the present article we complete Zalesskii's programme by dealing with the final case left open in [5], the double covers of the alternating groups. We derive this result from a corresponding result on the double covers of the symmetric groups. If one is only interested in spin characters, one easily sees that only 2‐powers can occur as prime power degrees. However from a combinatorial point of view it is natural to ask more generally: when is the number of shifted standard tableaux of a given shape a prime power? Since our method is independent of the prime, we will answer this question, showing that apart from a few accidental cases for small n only the 'obvious' partitions satisfy the prime power condition. Thus in turn for the spin characters, apart from exceptions for small n, 'obvious' spin characters of 2‐power degree are indeed the only ones (this confirms the conjecture stated in [5]).

Conventional methods of frequency measurement count the number of cycles in a given time or the number of clock pulses during one or more periods of the unknown signal. This approach is prone to error from the uncertainties associated with the gating of two signals. A novel comparator is described that eliminates this error. The frequency of an unknown signal is compared cycle for cycle with a reference. The comparator has two outputs; one of these indicates which of the two signals is at a lower (or higher), frequency while the other output is a pulse train with a repetition rate equal to the difference of the two frequencies. Applications of the comparator in difference clocks and in frequency meters are presented.

Molecular models of real fluids are validated by comparing the vapor-liquid surface tension from molecular dynamics (MD) simulation to correlations of experimental data. The considered molecular models consist of up to 28 interaction sites, including Lennard-Jones sites, point charges, dipoles and quadrupoles. They represent 38 real fluids, such as ethylene oxide, sulfur dioxide, phosgene, benzene, ammonia, formaldehyde, methanol and water, and were adjusted to reproduce the saturated liquid density, vapor pressure and enthalpy of vaporization. The models were not adjusted to interfacial properties, however, so that the present MD simulations are a test of model predictions. It is found that all of the considered models overestimate the surface tension. In most cases, however, the relative deviation between the simulation results and correlations to experimental data is smaller than 20 %. This observation corroborates the outcome of our previous studies on the surface tension of 2CLJQ and 2CLJD fluids where an overestimation of the order of 10 to 20 % was found.


BACKGROUND
Although bereavement programs are a common element of palliative medicine and hospice programs, few health care institutions currently offer universal bereavement services to all their patients. The elevated risk of serious physical and mental health problems among the bereaved is a strong argument for the development of universal institution-based bereavement programs as an element of quality care for family members of all patients who die.

OBJECTIVE
We describe the development of the bereavement program at Dana-Farber Cancer Institute (DFCI) where we conceptualized bereavement services as a preventive model of care.

DESIGN
We identified education, guidance and support as the primary constructs of the program. The essential components include a formal acknowledgement of the death of the patient by the cancer center, information about grief and what to expect, individual visits to assess coping, and staff support and education.

SUBJECTS
One hundred and forty bereaved families completed a survey about the bereavement program.

RESULTS
The findings indicated that the formal letter of condolence and the bereavement guide had a positive impact on the grieving of the respondents. Contact from the patient's oncologist and nurse was especially well received.

CONCLUSIONS
Bereavement programs can both help bereaved individuals adapt to their loss, and positively impact hospitals by enhancing the reputation of the hospital within the community and providing an avenue for identifying opportunities for improvement in care processes. We recommend that all hospitals implement basic bereavement programs for families of all deceased patients as the standard of care.

The study focused on the assessment of farmers' par tici tion in National Special Programme for Food Security (NSPFS) in Warawa Local Governmen t Area of Kano State. Data were collected from 100 randomly selected farmers' throu gh the use of interview schedule, while the information collected was analyzed using descri ptive statistics, regression (logit) and ranking. The result indicated that, the age of the farmers range from 15 to 72 with a mean of 37 years. They also have a mean household size of 13 m embers with an average farm size of 3.42ha as well as a mean farming experience of 22 years. Similarly, majority of the respondents (46%) have medium level of participatio n in NSPFS. Also farmers' age, years of awareness and farming experience were statistically significant (P<0.05; 0.0164, 0.0533 and P<0.01; 0.0054) to participation. Nevertheless, loc al leadership problems, inadequate quantity and quality inputs, diversion of inputs meant for t he Programme and inadequate Extension agents constitute the major constraints to the resp ondents' active participation in the Programme. It is hereby recommended that training a d development of local leadership, provision of adequate inputs as well as Extension p ersonnel will go a long way in improving farmers' participation in the Programme.


Adiabatic potentials corresponding to 62 electronic states, arising 'from various configurations of the C 2 -molecule which consists 'of two carbon atoms with two 2p-electrons each, are calculated taking into account the effect of 2s-shells. The complete adiabatic Hamiltonian of eight electrons, but not a so-called interaction operator, is used, and direct, exchange, higher permutation, and overlapping integrals are all taken into account. The Same effective charge lC is assumed for 2s, 2ptl, and two 2p77: orbitals, and the minimum electronic energy is obtained by varying lC for each nuclear distance. It is found that !ls-shells repel 2ptl electrons and attract 2p77:-electrons. Thus (s2t12, S2t12)1~O+ state, which was found to be .attractive and deepest when the effect of 2s-shells was neglected in the previous. paper, becomes very higher and repulsive. The results of the present calculation are that the deepest state is, (s2t177:, .,2t177:)1.4/1 and that (s2t177:, 2t1'ii3.)1::E1I+ and (s2t111:, s211:$o)1ll .. are next and third respectively.


It is, and it is bound to remain, a moot point whether the end of the cold war contributed to the end of Italy's 'First Republic'—and, if so, exactly how and how much. Yet it is a fact that, starting in 1992, the old party system of the post-war era crumbled and a new and still highly unstable one—born out of the new electoral law(s) enforced since 1994—took shape. Its main features have been a distinctly bipolar structure characterized by fragmented and fractious coalitions; a high degree of political litigiousness both across and inside political camps; and a growing role for their respective leaders as temporary 'federators'. Silvio Berlusconi on the centre-right and Romano Prodi on the centre-left have emerged as such leaders, albeit with significant differences between them. This period (1994–), now labelled as Italy's 'Second Republic', has basically coincided with the first steps of the Common Foreign and Security Policy (CFSP) of the European Union (EU), as outlined in the Treaty of Maastricht, signed in early 1992 and later perfected through successive revisions (in 1997 and 2000). Italy's own foreign, security and defence policy has been confronted with multiple challenges: first, not unlike many other European countries, it had to adapt to the broader post-cold war environment and its unknowns; second, it had to strike a new balance between its traditional Atlanticist and European inclinations, more or less neatly separated between the USA and NATO link on the one hand, and the European Community link on the other, which until then had neither really clashed nor connected; third, it had to adjust its new and shaky internal set-up to the new international and regional developments; fourth, it also had to cope with the ever growing risk of being marginalized and excluded from the various exclusive 'clubs' that seemed to take shape on certain policy areas: dedicated Contact Groups, the euro-zone, Schengen, permanent membership of the UN Security Council and others. The first Berlusconi government in 1994 was too short-lived to make a lasting impact on Italian attitudes and priorities, although it managed to send around some unconventional messages. Albeit briefly, the traditional bipartisan consensus on European policy, that dated back to 1977, seemed to be put into question. Berlusconi-I was soon followed by a series of governments—led by Lamberto Dini (1995–1996) and then Romano Prodi (1996–1998)—that tried to rehash the foreign policy traditions of the First Republic, possibly with an even stronger European flavour and focus. This was certainly due also to the centrality of the launching of European Monetary Union and its domestic implications: it is not by accident that the positive outcome of Italy's quest for EMU membership, in the spring of 1998, was soon followed by the collapse of the Prodi government,


The invention provides an automobile fender and a fabrication method. The automobile fender is fabricated by filling a polyurethane foam material into a PE (polyethylene) blow molding piece with side holes. Polyurethane foam for filling comprises a component A and a component B, wherein the component A is 47-54 parts by mass of polymethylene polyphenyl polyisocyanate (PAPI), with relative density of 1.2, a burning point of 218 DEG C, and viscosity of 900mpa*s; the component B is a mixture of polyether polyol, water and a foam stabilizer, and has viscosity of about 300-400mpa*s; bifunctional polyether polyol with a hydroxyl value of 108-196mgKOH/g accounts for 40-50 parts by mass; bifunctional polyether polyol with a hydroxyl value of 355-395mgKOH/g accounts for 3.4-10 parts by mass; the water accounts for 1.3-2.0 parts by mass; the organosilicon foam stabilizer accounts for 0.4 parts by mass; the component A and the component B are mixed uniformly and then react rapidly to generate the foam; the cream time of the mixed filling material is 30-150s; the gelation time is 1800s; and the foam volume multiplying power is about 12-18. Therefore, the obtained novel automobile fender has light weight, impact resistance and sound resistance.


The purpose of this paper is to critically reflect on two graduate international comparative education courses I taught at a mid-sized public university. Using a variety of readings and multimedia focusing on voices of international educators telling their own stories of struggle for a democratic education, these courses represent my effort to raise a 'glocal' consciousness among pre-service and in-service educators. In this paper, I describe how my educational and life experiences, which include living in parts of the 'global south' and 'global north,' influenced the global issues selected for discussion in these classes. Although there is clear evidence that the experiences I describe in these courses helped to develop a more "glocal" and critical consciousness among students, I conclude that there are always more questions to ask, stories to tell, and complexities to explore when comparing different educational approaches.

Studies of biological consequences of nuclear industrial contaminants in the environment increase in importance as the potential for exposure of wildlife populations rises. Thus, we examined levels of radiocesium (cesium-137) contamination in wood duck eggs from a Department of Energy nuclear facility in South Carolina during 1990. Radiocesium levels in individual eggs from 5 locations on the site ranged from below detectable concentrations to a maximum of 2.21 Bq/g wet mass. Eggs from an abandoned reactor cooling reservoir contained the greatest burdens; mean egg concentrations there were more than an order of magnitude higher than those from other locations studied. Eggs from a second radionuclide releases, all contained similar low radiocesium levels that were, on average, below detection limits. Variation in radiocesium concentrations of eggs from the most contaminated cooling reservoir was partitioned into within- and among-clutch variation. Approximately 33% of the variation in radiocesium content occurred among eggs laid by the same female, and may have resulted because females fed in both contaminated and uncontaminated habitats during egg formation. Radiation dose rates to developing wood duck embryos, resulting from internal and external sources examined in this study, were below those expected to affect hatchability or any other aspect ofmore » the breeding biology of these birds. Wood ducks and their eggs may be useful as bioindicators of radiocesium uptake, but we caution that local foraging patterns could cause variation in contaminant deposition within clutches. 45 refs., 1 fig., 2 tabs.« less


Objective. To determine the percentage of dental internship students who has the intention of make or not a university thesis. Material and methods. 139 dental intership students of San Martin de Porres University in Lima, Peru 2011 were polled through a questionnaire which evaluated three dimensions: attitudinal, academic and institutional. Results. The intention of dental intership students of the FO-USMP to make a university thesis is 54,68%. No significant differences were found in the intention to make the thesis in student's sex and age (p=0,892) (p=0,904). According to the dimensions studied the attitudinal character is favorable (61%), followed by institutional and academic. On the other hand, an 81,29% know the scientific method in theory, but a 69,78% did not consider it sufficient for the development of a thesis, for this reason, the promotion of research workshops 90,65% and production of thesis courses 89,93% obtained the highest percentages. Conclusions. Over half of students intend to make a thesis, academic is the dimension that requires further attention and attitudinal character wich obtained wide acceptance. Sex had no influence on the decision of making thesis. (Kiru 2012;9(2):125-130).


There are numerous oil fields that are approaching the end of their lifetime and that have great geothermal potential considering temperature and water cut. On the other hand, the oil industry is facing challenges due to increasingly stringent environmental regulations. An example of this is the case of France where oil extraction will be forbidden starting from the year 2035. Therefore, some oil companies are considering switching from the oil business to investing in geothermal projects conducted on existing oil wells. The proposed methodology and developed conversions present the evaluation of existing geothermal potentials for each oil field in terms of water temperature and flow rate. An additional important aspect is also the spatial distribution of existing oil wells related to the specific oil field. This paper proposes a two-stage clustering approach for grouping similar wells in terms of their temperature properties. Once grouped on a temperature basis, these clusters should be clustered once more with respect to their spatial arrangement in order to optimize the location of production facilities. The outputs regarding production quantities and economic and environmental aspects will provide insight into the optimal scenario for oil-to-water conversion. The scenarios differ in terms of produced energy and technology used. A case study has been developed where the comparison of overall fields and clustered fields is shown, together with the formed scenarios that can further determine the possible conversion of petroleum assets to a geothermal assets.


Recurrence frequency of acute myocardial infarction was studied in three groups of patients: in the first group (p=93) intravenous laser therapy was carried out daily, during 5—6 treatment sessions with the total dose of radiation of the red spectrum 0.976 J. Patients of the second group (p=30) got systemic thrombolysis with avelisinum, celiase, streptodecase according to the standard patterns of high or middle tempo of injections. In the third group (p=50) the traditional treatment was carried out (nitrates, beta adrenoblockers, Ca antagonists) which was taken as a basis treatment in other groups.Among the patients of the first group the recurrence frequen су was 2.2% versus 16.7% and 14% in the second and third groups respectively, what proves possibility of myocardial infarction recurrence prophylaxis by the method of intravenous laser therapy.


Abstract This work focuses on the challenging process called Petlyuk distillation column. This plant has interesting properties for reducing the energy consumption up to 30% and the capital investment cost. However the dynamic control of the divided-wall column has been explored in a relatively small number of papers. The control problem is more difficult here since the six sections of the column are coupled. In this work, the control problem is addressed systematically by determining the optimal number of controlled variables (optimal sensor location, OSL) and the control structure design (CSD), simultaneously. It is done by grouping both problems in a single procedure called minimum squared deviation (MSD). This strategy considers both set points and disturbances effect, and the interaction in the controller structure (diagonal, full or sparse) is taking into account, via net load effect (NLE) index, for deciding the best one. A comparison of the dynamic controllability with two other strategies such as self-optimizing control and null space method is presented here.

Scalar tetraquark states are studied within the diquark-antidiquark picture in a non-relativistic approach. We consider two types of confining potentials, a quadratic and a linear one, to which we also add spin-spin, isospin-isospin, and spin-isospin interactions. We calculate the masses of the scalar diquarks and of the ground-state open and hidden charmed and bottom scalar tetraquarks. Our results indicate that the scalar resonances D �(2400) and Ds(2632) have a sizable tetraquark amount in their wave function, while, on the other hand, it turns out that the scalar states D � s0(2317) and X(3915) should not be considered as being predominantly diquark-antidiquark bound states. We also investigate the masses of light scalar diquarks and tetraquarks, which are comparable to the measured masses of the light scalar mesons.


In fall 2015 the Chronicle of Higher Education reported on an American Association of Universities' study that one in four women experience sexual assault or misconduct on college campuses. One in four—that are reported. And that number includes only women, primarily cisgender identified. On my campus, students, faculty, and staff felt the world remapped by that statistic. University of Pittsburgh chancellor Patrick Gallagher wrote an open letter to our university community, stating that


Secondary Vocational education is responsible for cultivating the talents for the economy, as well as to promote scientific and technological research and innovation of the two key responsibilities. Although secondary vocational schools is based on cultivating the practical ability of students, math and other basic disciplines of teaching status is not optimistic. Math experiments based on information technology can stimulate the enthusiasm of students to learn math, improve the overall quality of vocational students, and provide a solid foundation for vocational students to take the professional operation and secondary vocational education. It in-depth implements the concept of combining course with engineering and engineering of "Learning content is work, through the work to achieve learning" in theoretical practice integration curriculum. In this study, we investigated the status quo of math experiments and students' attitude to math experiments and put forward the corresponding suggestions and strategies.

Maintaining adequate measuring accuracy and repeatability at radiated emissions testing facilities (e.g., open field sites and semi-anechoic chambers) is necessary to maintain credibility. Although catastrophic failures are usually readily apparent, slow changes to measurement accuracy or minor failures are difficult to detect. Annual or semi-annual preven tative maintenance is necessary to insure accuracy, but cannot insure repeatability (i.e., continued accuracy) between maintenance periods. A method is described ap plying statistical quality control to weekly measure ments of a standard, multifrequency source to produce a running control chart of EMI measuring system repeatability.


The sample solutions were prepared by mixing equal volumes of any two of the 1.00×10−2 mol/l solutions of the 1:2 complexes of copper(II) with ethylenediamine, N,N-dimethylethylenediamine, N,N-diethylethylenediamine, 1,3-diaminopropane, L-alanine, L-serine, N,N-diethylglycine, and β-alanine, where an equivolume mixture of water and methanol was used as the solvent. The X-band ESR measurements for these sample solutions were carried out at the temperature of liquid nitrogen. The observed ESR line shapes showed that only the mixed-ligand complexes are formed almost quantitatively in all the solutions except two: equivolume mixtures of the two complex solutions of ethylenediamine and β-alanine and those of ethylenediamine and N,N-dimethylglycine, in which the coexistence of two or more complex species was clearly demonstrated. The ESR line shapes and, furthermore, the intensities of the visible absorption indicated that the symmetry of the ligand field of the mixed-ligand complexes is as axial as that of the...

It is estimated that about 50 percent of China's annual gross domestic product (GDP) is needed to compensate the environment cost, it is urgent to shift China's massive economy to green one. In China's 13th Five-Year plan (2016-2020), China plans to establish the "ecological civilization", incorporating air pollution control, energy consumption control targets, and green finance, laying out China's transition towards a green and low-carbon economy. However, the green finance system establishment demands many auxiliary systems, such as fiscal support, legal institutions, and other taxation aids. From global perspective, the green finance system also helps to reduce the environmental risks worldwide both the countries along ancient silk roads and the European countries. On the other hand, investment in Europe has still not recovered from pre-financial crisis levels. The European Union has to massively accelerate investment to meet its climate and energy obligations with an annual investment gap of €100 billion in funding Europe's energy infrastructure to reach its climate and energy targets. The European Union plans to re-boot the Capital Markets Union to help meet this challenge by setting up an expert group on sustainable finance. Both China and Europe are facing the climate challenge and they have to deal with it together. Chinese government advocates public-private partnership (PPP) model to improve the funding environment and actively seek way out. This paper aims to arouse the awareness of cooperation in Europe and China in green financing and hi-tech field, by creating a framework to improve the financing mechanism of environmental protection and green economy.


Lee SJ, McCall WD, Jr., Kim YK, Chung SC, Chung JW: Effect of botulinum toxin injection on nocturnal bruxism: A randomized controlled trial. Am J Phys Med Rehabil 2010;89:16–23. Objective: To evaluate the effect of botulinum toxin type A on nocturnal bruxism. Design: Twelve subjects reporting nocturnal bruxism were recruited for a double-blind, randomized clinical trial. Six bruxers were injected with botulinum toxin in both masseters, and six with saline. Nocturnal electro-myographic activity was recorded in the subject's natural sleeping environment from masseter and temporalis muscles before injection, and 4, 8, and 12 wks after injection and then used to calculate bruxism events. Bruxism symptoms were investigated using questionnaires. Results: Bruxism events in the masseter muscle decreased signifi-cantly in the botulinum toxin injection group (P (cid:1) 0.027). In the temporalis muscle, bruxism events did not differ between groups or among times. Subjective bruxism symptoms decreased in both groups after injection (P (cid:2) 0.001). Conclusions: Our results suggest that botulinum toxin injection reduced the number of bruxism events, most likely mediated its effect through a decrease in muscle activity rather than the central nervous system. We controlled for placebo effects by randomizing the interven-tions between groups, obtaining subjective and objective outcome measures, using the temporalis muscle as a control, and collecting data at three postinjection times. Our controlled study supports the use of botulinum toxin injection as an effective treatment for nocturnal bruxism.

High Latitude Dust (HLD) deposition in the surface snow layer in two distant locations in Svalbard (Hornsund and Pyramiden) were collected during the June/July 2019 field campaign and examined in the laboratory. Despite the differences in their climate and topography, both locations are characterised by very similar spatial patterns of the deposition. On the one hand, strong linear negative relationship between the altitude of the sample taken and its concentration was found in low altitude (below 300 m a.s.l.), suggesting a strong influence of local HLD sources. On the other hand, almost constant concentrations were found at higher elevated sampling sites (above 300 m a.s.l.). This suggests a predominantly long-range transport in high altitude areas. The importance of local sources in the lower altitude corresponds well with the generally higher concentrations of HLD in the Pyramiden area. This region has a drier, continental climate and more deglaciated bare land surfaces, which favour more sediment to be uplifted in comparison with the more maritime climate of Hornsund area in the southern part of Svalbard. The spatial division between the local and long-range transport is supported by the proportion of certain lithophile elements in the altitude gradient.


Reflective teaching method carries with itself innovation because it aims at improving teaching quality,and pursues rationality in teaching practice.The general trend of the world education indicates that the focus of reform has turned to the training of professional and research-oriented teachers,and reflective teaching method has great significance in this process.Thus,a correct attitude towards new approaches and research in reflective teaching is what TCFL needs.


In cluster systems the execution of a parallel program is non deterministic, which makes the debugging of parallel programs very difficult. This non determinism is mainly caused by all kinds of disturbances or perturbations existing in the running environment.This paper studies the characteristic of perturbation that a debugger imposes on debugged parallel programs while user debugs a parallel program in interactive mode, which is very difficult and very helpful for the design and implementation of a practical debugger in cluster systems. First of all, several techniques that are used to decrease perturbation are briefly discussed. Then, we build our own message passing model of parallel programs in cluster systems. Our model is different from others in that we introduce D max and D min that represent the maximum latency and minimum latency of messages in cluster systems respectively. In order to describe the executive character of parallel programs accurately, we define the terms of state freezing and equivalent execution. Then, we analyze the detailed conditions of perturbation that a debugger imposed on a parallel program. Finally, we find out the conditions under which the debugger would produce perturbation and formally prove these results.According to our results, we design two algorithms that can inform the user of the perturbation that a debugger has imposed on debugged programs in real time. We have developed a debugging tool, DENNET in cluster systems. Those algorithms have been integrated in DENNET and the corresponding debugging mode has been named 'pure mode'. When debugging a parallel program, users can choose 'pure mode' or not. Acknowledge time and latency are two key parameters in our algorithms. At the end of this paper, the testing results of these two parameters are given.


Although the underrepresentation of women in academic philosophy is well-known and hard to overlook, philosophers started to pay more attention to the actual data on and potential explanations of the underrepresentation of women in philosophy only in the last decade and predominately
 in anglophone countries. The data I present in this paper deal with introductory logic courses at German universities (gender of textbook authors, gender of logic course instructors, student grades by gender at one university). Two results are particularly noteworthy: For one, logic teaching
 in Germany is currently predominantly male and even more male than philosophy teaching as a whole. For another, there is no evidence for any differences between grades of female and male students. The student grade data, however, illustrate how statistical phenomena like Simpson's paradox
 can explain how male students can appear to achieve better grades than female students even if there is no underlying difference: When correcting for students' major (philosophy vs. STEM), logic grades of male and female students are remarkably similar. Although the scope of the
 data presented here is limited, they allow to add further details to an emerging map of the profession. I close with some suggestions for avoiding stereotyping logic as "male".


In this article a review is presented of studies on polypropylene and ethylenepropylene-diene terpolymer nanocomposites, reported in the period from 1970 to 2007. The article has two major parts; first it discusses TPVs made up of a thermoplastic and a volcanizable elastomer, and second it explains about nanocomposite technology and its remarkable effects on the properties, morphology, and applications of TPVs.


This study examined the relationship of internalized oppressions to the psychological distress of 304 lesbian and bisexual women. In addition, it investigated whether self-esteem and social support mediated the relationship between internalized oppressions and mental health. Results indicate that after controlling for education, internalized sexism (IS) and internalized heterosexism/internalized homophobia (IH) are significant predictors of psychological distress and account for 17% of the variance. The interactions between IS and IH are not significant predictors of psychological distress. Furthermore, results reveal that self-esteem and social support fully mediate the relationships between IH and psychological distress. Social support was also found to fully mediate the relationship between IS and psychological distress. However, no support was found for the mediational role of self-esteem in the link between IS and psychological distress. Research and practice implications are discussed.


After the advent of the heart-lung machine, few surgeons continued to use the OPCAB technique, Among those were Benetti and Buffolo from South America, who published in the early 1990s the first two large series on OPCAB surgery [1-3].


In many communication or radar systems, the bandwidth occupied by the signal, and hence the bandwidth in which we are interested, is only a very small percentage of the centre frequency. The output noise from, for example, an IF filter will be white over most of the filter passband. Thus narrow-band white noise is both a simple and a practically interesting case. This Appendix considers the analysis of coloured noise by breaking the frequency band into a number of sub-bands, each with a different noise level.


In this thesis I have explored the possibilities of using mobile phones based on Android platform for indoors positioning. An application that enables such positioning was developed and tested especially to confirm my thesis.
The first part of the thesis explains the various kinds of location-based services, their usefulness and problem possibilities. This section also introduces the reader to the field and explores the potential of such technologies and correlated methods. Their comparison has led me to focus on using the specific method of Location Fingerprinting (LF). This method determines the position in space relative to a unique value of the wireless signal intensity.
In the second part of the thesis this technique was implemented in a software solution using two programs. The first is a generic one used to capture the reference points, the second one is used to practically demonstrate a mobile phone being used for self-positioning within the building of the Faculty of Computer Science (in Ljubljana).
The third part of the thesis is dedicated to testing and exploring the potential for further research and solutions that would be even more accessible and user-friendly.


The Anthropocene Epoch is a crucial conceptual breakthrough not only for stratigraphy but also for the humanities. The question, raised by Chvosek (2023), is how best to create engagement between the sciences of the Anthropocene and the study of values, hopes and power in the world's many cultures past and present. In response, this piece makes three points. First, it discusses some of the collaborations that have already taken place between humanists of various kinds and the scientists providing the stratigraphic evidence for the Anthropocene Epoch. Second, it notes that the 'Anthropocene' remains, at core, a stratigraphic concept and that the new epoch is now well supported by physical evidence. Third, it shows that the recent idea of an Anthropocene 'event' (Gibbard, 2022) does not invite engagement with the humanities. The overall argument is that the integrity of expertise must be maintained even while we encourage the cross‐disciplinary understanding crucial to addressing our global environmental challenge.


this paper examines the conversion method of the imbalanced exciting force of equipment from a bench test to a ship hull structure.A formula of the exciting force transferred to the ship structure is conducted,and a simplified method of analyzing the coupled vibration between marine equipment and the ship structure is also proposed.Based on vibration theory,the coupled vibration model of equipment and the ship structure is established by regarding equipment,the vibration isolator and installation foundation as a multi-degree-of-freedom vibration system.The exciting force transfered to the installation foundation is obtained.On that basis,a formula of the exciting force transfered to the ship hull structure is then obtained,and a simplified method for analyzing the coupled vibration between equipment and the ship hull structure is proposed and verifired.Result shows that the exciting force transferred to the ship hull structure are not only related with the equipment exciting force,but also with the mass of equipment,the stiffness and damping of isolators and the stiffness of the ship hull structure.Study also shows that the simplified method proposed has high accuracy and can meet engineering requirements.


Analysis of vote data suggests that, among other performance factors, ethnicity plays a major role in the acceptability of political marketing approaches of partisan politics in Ghana. This features quite prominently in the ethnic based voting pattern that has prevailed over the years and the communal voting pattern that is emerging in Ghana as a result of increasing urbanization. The analysis makes it evident that political parties with very strong ethnic support bases are those that have stood the test of time no matter what marketing tools or approaches are employed, though political marketing gains to a large extent depend on the features of the political product, the political product benefit and the political marketing support services. The paper compares the results of the four different elections of the Fourth Republic of Ghana and attempts to make inferences on the effects of ethnicity on the voting patterns of the four (4) Presidential elections in the Fourth Republic. The analysis uses the voting patterns as a pointer to the acceptability and effectiveness of a political party's marketing approach and by deduction, analyzes which political marketing variables contribute to the acceptability of political parties. It also attempts to generate understanding of the political marketing variables such as dimensions of the Political Market, the Political Product and the 'Political Product Support Services' and compares effects of these variables with effects of ethnicity on political marketing outcomes in Ghana. The paper specifically compares features of the political product which include Party Philosophy, Perceived Party Identity, Manifesto, Political Party Leadership, Previous Performance, Particularistic Benefits, Party Paraphernalia on elections outcomes among identified or classified ethnic groups at regional or communal level. In addition, the analysis reveals that personality, perceived party image or identity of the political party and communication are salient in determining political marketing outcomes or fortunes of a political party and to a less extent political product benefits based on past performance and experiences, whereas effects of particularistic benefits and party paraphernalia or the political marketing support services are less prominent.


The crystallization technology of saccharification liquid from broken rice for preparing glucose injection was optimized by central composite design and response surface methodology(RSM) with the concentration of saccharification liquid,amount of inoculating seed and crystallizing time as independent variables and the yield of glucose crystal as dependent variable.The results showed that the binomial regress equation fit the data well(r=0.916 0).The optimal technology was as follows: the saccharification liquid was condensed to the concentration of 100%-150%, amount of inoculating seed was 2%-3%(based on the original glucose concentration),and crystallizing time was 50-60 h at room temperature.

BACKGROUND
Vitamin D is involved in cardiac contractility and myocardial calcium hemostasis, and Vitamin D deficiencies are known to cause various cardiovascular disorders and have been linked with sudden cardiac death.

AIM
The present study evaluates repolarization distribution, represented by QT interval, corrected QT interval(QTc), QT dispersion (QTd), Tp-e interval, Tp-e/QTc ratio, JT interval, JT dispersion and Tp-e/JT ratio, in children with vitamin D deficiency; and determines the relationship between ventricular repolarization anomalies and vitamin D deficiency.  Methods: The study included 50 adolescent patients with vitamin D deficiency, 50 adolescent patients with vitamin D insufficiency and 50 age-matched controls (vitamin D level > 30ng/ml). QTc duration, QTc dispersion, JTpeak duration, JT dispersion, Tp-e, Tp-e/ JTpeak and Tp-e/ QTc ratio were determined via electrocardiogram.  Results: Tp-e duration was significantly longer in patients with vitamin D deficiency or insufficiency (p < 0.01), while Tp-e/QTc and Tp-e/JTpeak were found to be increased in the same group (p < 0.01). QT dispersion and JT dispersion were found to be significantly higher in the deficient group when compared to the other groups (p= 0.045 and p= 0.025, respectively).  Conclusion: The present study, performed on adolescents, is the first in literature to assess the relationship between ventricular repolarization anomalies and vitamin D deficiency.


of stratified and proportional sampling-two important topies often ignored in elementary texts -is very pleasing. The chapter on estimation, which often also gets short shift in beginning texts, is good. Hoel's treatment of hypothesis testing begins with consideration of Type I and Type II errors and builds upon these central ideas. The chapters on correlation and regression are, with the exceptions noted above, clearly developed and sound. Under the heading, &dquo;Special Topics,&dquo; Hoel presents chapters on chi-square, non-parametric tests, analysis of variance (anova) and time series and index numbers. The author's idea is that these topics are less central to an introductory course in statistics than those mentioned in the paragraph above and should be considered at the end if time allows. With the exception of chi-square, this is probably a reasonable approach. The material on chi-square is based almost completely on intuitive appeal, but is sound as far as it goes. The non-parametric chapter is naturally rather limited, but does mention rank correlation. One-way classification anova is done well, but the two-way section sluffs over just too many points from model to assumptions to expectations. The chapter on time series and index numbers appears to be purely an appeal to business and economics sections in applied statistics. The treatment is rather good at the level attempted, especially of index numbers, but it certainly does not mesh with the rest of the book. In terms of general consideration, Hoel's text must be rated as superior. The writing is lucid, the examples are clear, the approach is steadily intuitive and does not take cover in mathematics when


This paper consists of two main parts. The first part is devoted to the investigation of the variations in trajectory and in the cost of an optimal control system subject to small deterministic and stochastic disturbances arising either from changes in the parameters of the plant or from the errors in the estimation of state variables. The second part deals with the inverse problem of estimating the changes in the plant parameters provided that the variations in trajectory can be observed. Both fixed and time-dependent parameter cases are considered.


This paper describes the design of automated machines and dedicated by design, including commissioning. Assembly and testing of control functions to customer satisfaction.


In this paper, we introduce generalized quadratic forms and hyperconics over quotient hyperfields as a generalization of the notion of conics on fields. Conic curves utilized in cryptosystems; in fact the public key cryptosystem is based on the digital signature schemes (DLP) in conic curve groups. We associate some hyperoperations to hyperconics and investigate their properties. At the end, a collection of canonical hypergroups connected to hyperconics is proposed.


Multihoming has been traditionally employed by enterprises and ISPs to improve network connectivity. Recently, there are increasing interests in other benefits derived from multihoming. In particular, it can be applied to improve network performance, lowering bandwidth costs, and optimizing the way in which upstream links are used. Multihoming can be applied in link layer, network layer or transport layer in the network protocol stack. This paper first presents an overview of multihoming in the network layer. The focus is put on available deployments of multihoming, namely, BGP and NAT. Second, a few challenges of BGP and corresponding proposals to solve these challenges are listed. The aim is to put things in perspective, point out why the challenges are so difficult to solve at present and summarize the main lessons learned.


For the characteristics of time consuming, complicated steps and lack of automatic of the traditional water quality monitoring, an automated real-time online water quality monitoring program based on wireless sensor network (WSN) is presented in this paper. This system combined micro-UV-Vis Fiber Optic Spectrometer with ZigBee Wireless Communication Technique to constitute Wireless Sensor Network Node which is placed at the monitoring water,and then used the ZigBee protocol's real-time transmission and monitor data to raise the automation and monitoring level. This paper discussed the network architecture based on ZigBee protocol, maked design of Optical System of sensor node and the hardware and software and then maked spectroscopy signal real time collection and communication test. The experiment results show that the industrial monitoring system of water quality has few transmission errors, better anti-jamming ability, small size of sensor node, fast inspection speed. All these features are suitable for real-time and continuous monitoring the pollution level of industrial sewage.


Parkinson's disease is a progressive degenerative illness that mainly affect dopaminergic neurons in elderly individuals. A buildup of proteinaceous inclusions called Lewy bodies can be observed within these affected dopaminergic neurons. Clinically, Parkinson's disease is typically manifested by tremor, bradykinesia, postural imbalance and rigidity of muscles. As the disease advances over time, non-motor signs may also appear like depression. No precise cause for Parkinson's disease is yet identified but several risk factors were determined like exposure to pesticides. Treatment of Parkinson's disease is mainly focused toward alleviation of symptoms but with no ability to halt the development of neurodegeneration. As such, the search for new therapeutic agents is still ongoing to introduce new drugs against Parkinson's disease with neuroprotection capacity. In this trend, some epidemiological studies had suggested that there is a potential negative association between exposure to β2-adrenceptor agonists and risk of Parkinson's disease. Also, small clinical trials had concluded that the adjunct use of salbutamol, a known β2-adrenceptor agonist, may have a beneficial effect in Parkinson's disease patients treated with levodopa. This beneficial effect of salbutamol may be attributed to the ability of β2-adrenceptor agonists to lower expression of α-synuclein according to cell line studies. Also, β2-adrenceptor agonists may be able to increase brain extraction of levodopa in patients with Parkinson's disease as seen in animal studies. In this computational study, we evaluated the ability of salbutamol to selectively bind and inhibit MAO-B enzyme as an additional and potential beneficial effect in Parkinson's disease patients under levodopa therapy. The results of this study predicted that docking orientation, ligand movement root-mean-square deviation and MM-PBSA binding energy throughout simulation interval are more favorable toward salbutamol capacity to bind to MAO-B as compared to MAO-A. However, these computational findings must be further validated both in vitro and in vivo.


To predict the immunogenicity of the FGF5 protein coded for by the FGF5 from sheep and characterize its structure and epitopes from a bioinformatics approach,the cDNA of FGF5 gene was cloned from sheep by using PCR with a pair of primers designed according to the conserved cDNA sequence of cow homologous FGF5 gene.The physico-chemical properties,solubility,surface accessibility,post-translational modification sites,hydrophilicity/hydrophobicity,secondary structure,specific epitopes,and 3D structure of FGF5 protein were analyzed and predicted by using the ExPASy bioinformatics tools ProtParam,SOSUI,Emini,MotifScan,HNN,and SWISS-MODEL in combination with bioinformatics software(TMH-MM2.0,SignalP 3.0,TargetP 1.1和PSORTⅡprediction,Gene Runner,DNAMAN,etc.).Results showed that FGF5 protein consisted of 270 amino acids and had the following characteristics:molecular formula:C1315H2085N389O378S6;molecular mass:29.5847 ku;theoretical isoelectric point:10.59;absorbance(A):0.864(280 nm);half-life:30 h.22 post-translational modification sites,numerous highly hydrophilic regions,and 11 potential epitopes expressed as a soluble protein.The FGF5 protein coded for by the FGF5 gene may be made polyclonal antibody because of its soluble protein expression and immunogenicity.


On the basis of situation calculus, formalisms of agents' belief and intention using the possible world semantics are represented in the multi-agent system. We introduce time parameter and communication predicate into the earlier ConGolog, thus extending the temporal features and strengthening the interaction among agents in ConGolog. What's more, a cooperation model about the multi-agent system is put forward. At last, with extended ConGolog, a case of the multi-agent system is specified. The multi-agent system based on the extended ConGolog embodies features including interaction among agents and reason about action in the dynamic and incompletely known environment, and provides a theoretical foundation and method of implementation for constructing complex multi-agent collaboration systems


The semiotics of Charles Sanders Peirce is proposed as a theoretical framework that can model more adequately than conventional theories in psychology the emotional transformations in cultural practices that rest squarely upon self-transcendence as the basis for healing. For illustration, the Peircean notion of the sign is applied to an analysis of spirit healing in Puerto Rico. Clinical implications for psychotherapy in general, and treatment for alexithymia in particular, will be explored.


THE CONSTITUTION of India guarantees to all persons equality and equal protection of law under article 14 as a fundamental right. In this connection article 44 speaks about the uniform civil code for Indians. However, since long various provisions of the personal laws followed by the different communities deny equality to women in general. While Hindu personal law has been extensively reformed, personal laws of other communities have been by and large, left untouched. It is true that Hindu women have gained new rights in the processes of transformation and empowerment. There are still, some grey areas, which have to be taken care of, for achieving total equality.In this context the author reviews a which is titled UNIFORM CIVIL CODE.

We report on brain SPECT analysis of regional cerebral blood flow (rCBF) in late life chronic fatigue syndrome (CFS) patients and compare their results with patients with late life depression and elderly normal controls 45 years and older. We attempted to distinguish CFS from normals and patients with depression and applied the findings to understand the pathophysiology of the illness. We studied 33 patients with CFS (55 ± 10 years), 26 patients with late life depression (62 ± 8 years), and 19 normal controls (66 ± 8 years); 43 other normal controls had only ¹³³Xe rCBF measurements (66 ± 8 years). We evaluated rCBF quantitatively with ¹³³Xe images and qualitatively with high resolution imaging using 99mTc-HMPAO. We found that rCBF in CFS measured by ¹³³Xe varied between 35 and 41 ml/min/l00g in both hemispheres, p < 0.0001 and 0.05; similar findings were observed in depression. In CFS 99mTc-HMPAO imagain demonstrated right orbitofrontal and marked right dorsofrontal hypoperfusion at 58% to 66% of the maxi...


The habit of inducing plant galls has evolved multiple times among insects but most species diversity occurs in only a few groups, such as gall midges and gall wasps. This phylogenetic clustering may reflect adaptive radiations in insect groups in which the trait has evolved. Alternatively, multiple independent origins of galling may suggest a selective advantage to the habit. We use DNA sequence data to examine the origins of galling among the most speciose group of gall-inducing scale insects, the eriococcids. We determine that the galling habit has evolved multiple times, including four times in Australian taxa, suggesting that there has been a selective advantage to galling in Australia. Additionally, although most gall-inducing eriococcid species occur on Myrtaceae, we found that lineages feeding on Myrtaceae are no more likely to have evolved the galling habit than those feeding on other plant groups. However, most gall-inducing species-richness is clustered in only two clades (Apiomorpha and Lachnodius + Opisthoscelis), all of which occur exclusively on Eucalyptus s.s. The Eriococcidae and the large genus Eriococcus were determined to be non-monophyletic and each will require revision. (C) 2004 The Linnean Society of London.


Our analysis is intended to fill a gap in the sense that the focus of our study is on the challenges of the compliance function and their responses, putting into complex perspective the lack of and the need for striking a delicate balance between the quality of the international and national legislative environments and the role of ethical and due diligence frameworks. As a result of digitalisation, FinTech enterprises have become unavoidable in the world of financial services, which has had the effect that the business and risk models of incumbent players have changed, exerting a strong influence on the regulatory environment and in parallel on the development and change of trust and reliability as well as ethical and prudent conduct. Inevitably, regulation will always fall behind new needs and new emerging technologies, since authorities need to develop a thorough understanding of the functioning and risks of these technologies in order to establish adequate regulation of them. The compliance function must find its place and role in this changing environment in order to be able to efficiently support financial sector participants in their duty to comply with rules and ensure fair and ethical conduct.


Abstract In this paper autotuning and self-tuning methods for Dynamic Matrix Control (DMC) are presented with application to single-input single-output (SISO) processes which can be approximated by a first-order-plus-dead-time model. In order to validate the method a nonlinear control valve system described by a Wiener process is simulated. This process was identified by a Hammerstein model and controlled by DMC with output compensator. The proposed tuning methods have its performance compared to another standard method found in literature, showing more conservative results regarding smoothness of the control action while maintaining adequate performance on set-point tracking.

Imagine you live in a developing region there the population is growing rapidly and there is a demand for more urban neighborhoods. Therefore, you must build new homes and towns for emergency without the necessary urban and regional traffic networks. You always see congested avenues and passages and the traffic flow is jammed. At the same time, the new towns are neither satisfactory for residents nor gorgeous objects for investors and tourists. You believe that your city needs modern urban and regional transportation networks to breath do you not? Author's sense.


The metagenomic DNA of uncultured microorganisms from biogas digester was extracted by indirect extraction,end-blunted and ligated with cosmid vector of pWEB:TNC. A metagenomic library containing 30 000 clones was constructed , the stochastic Analysis of the library indicated that: the average size of the foreign DNA fragments was 40 kb and the capacity of the DNA cloned in the library was 1.2×106 kb. One of the positive clones pGXN100 that show black hydrolysis circles in Esculin plates was subcloned,sequenced and analysed. The results showed that the putative β-glucanase gene had a 1 863 bp ORF,encoding a protein with 620 amino acids sharing 76% and 85% identity with another β-glucanase gene AN292 for DNA and protein levels respectively. The structure functional domain analysis of Unglu100 using SMART software showed it maybe one of beta-glucoside specific PTS system transport proteins.


Appendicitis is the most common indication for urgent surgery in children. Single-incision laparoscopic surgery (SILS) has further improved surgical outcomes. In this study we compared SILS and conventional in terms of peroperative difficulty and outcomes. A retrospective chart review was performed interesting all patients operated for acute appendicitis in the department of pediatric surgery Hedi Chaker hospital and department of surgery Habib Borguiba hospital between January 2006 and December 2016. Among the total of 181 patients, LA and SILS were performed respectively on 51 (28.2%) and 137 patients (71.8%). In 41.9% of patients of conventional LA it was a complicated appendicitis and in 29.8% of SILS group it was a complicated appendicitis (p=0.22). The mean operative time was 63.7 min for the conventional LA group and 71.79 min for the SILS group, it was not statistically significant (p=0.046). Conversion was made in 13.7% of patients in the conventional LA and in 5.8% in patients with SILS (p=0.14). The median length of hospital stay was for the conventional LA group 3.5 days and for SILS group 2.3 days (p=0.04). The current study found that SILS provided comparable surgical outcomes to conventional LA and did not result in increased postoperative complication rates.

In a series of recent talks and articles, Theresa Biberauer, Anders Holmberg, Ian Roberts, and Michelle Sheehan argue that the final-over-final condition (FOFC) is an absolute universal regulating structure building. Yet, many languages deviate from FOFC thus suggesting that this condition is not "surface-true". The question therefore arises what factors make languages violate FOFC on the surface. In order to answer this question, we need a typology of FOFC-violating languages, as well as a detailed description of such violations. In this short essay, I describe FOFC violations in Gbe and some creoles, while relating the observed phenomena to some theoretical questions they raise.


Summary The design and control of a novel proof-of-concept active jet engine intake using Nickel-Titanium (Ni-Ti or Nitinol) shape memory alloy (SMA) wire actuators is used to demonstrate the potential of an adaptive intake to improve the fuel efficiency of a jet engine. The Nitinol SMA material is selected for this research due to the material's ability to generate large strains of up to 5 percent for repeated operations, a high power-to-weight ratio, electrical resistive actuation, and easy fabrication into a variety of shapes. The proof-of-concept engine intake employs an overlapping leaf design arranged in a concentric configuration. Each leaf is mounted on a supporting bar that rotates upon actuation by SMA wires electrical resistive heating. Feedback control is enabled through the use of a laser range sensor to detect the movement of a leaf and determine the radius of the intake area. Due to the hysteresis behavior inherent in SMAs, a nonlinear robust controller is used to direct the SMA wire actuation. The controller design utilizes the sliding-mode approach to compensate for the nonlinearities associated with the SMA actuator. Feedback control experiments conducted on a fabricated proof-of-concept model have demonstrated the capability to precisely control the intake area and achieve up to a 25 percent reduction in intake area. The experiments demonstrate the feasibility of engine intake area control using the proposed design.
