Summary. The purpose of the current paper is to analyze the perception of the first-, third-, and fifth-year students of the Faculty of Education at University of Extremadura in relation to their role in virtual-platform based learning. In order to do that, it was used a descriptive quantitative study method with the help of a questionnaire. The results showed that the year does not have influence on the perception. Students who consider the learner autonomy important show a greater degree of satisfaction with this type of education. Moreover, they prefer the professor to provide them with information about the course, delegating certain responsibilities to students.


The spatial data are processed via editing, query and other complicated analysis with spatial arithmetic operators provided by Oracle Spatial and SQL. In general, abnormal conditions will not occur in the operation with spatial arithmetic operators. In case the number of points of a polygon reaches 60000 or the number of inner rings of a polygon exceeds 200, errors may occur in the intersection overlay operation for spatial geometrical data and the connection between the system and Oracle database will be interrupted. For specific situation of GIS application in China, a polygon of a single parcel, as may occur in land resource investigation, sometimes includes 90000 points, even exceeding 120000 points, and the number of inner rings may far exceed 200. A bug is discovered by the authors in the application of spatial overlay analysis on the national city and county administrative map and national land use map at scale of 1:4000000. After a lot of tests and discuss with Oracle Corporation, the bug is finally confirmed by Oracle Corporation as a new bug (with bug ID of 3146244). To address the limitation of Oracle Spatial in processing vast massive spatial data, an algorithm of "Coordinate reduction intersection overlay" is presented after deeply analyzing the cause of the bug. The appropriate thresholds are decided depending upon the accuracy of analysis for spatial data overlay. Furthermore we have developed an extended module based on this algorithm. The correctness and validity of the solution on the algorithm have been testified by using the same spatial data in which the bug occurred for Oracle Spatial. The study results have been used in the land resource investigation and other fields in Zhejiang province of China.


Abstract This article focusses on South Africa's position regarding the nuclear Non‐Proliferation Treaty; an issue which was pushed into prominence by the Russian allegation in August 1977 that the Republic was on the verge of testing a nuclear device. The Soviet Union's objective was to embarrass the Western powers during the Lagos Conference on Apartheid, as well as to bring them in disrepute among African countries during the sessions of various United Nations bodies where South Africa's nuclear potential was discussed. Subsequent reaction from especially the United States shows that the Carter Administration will use continued nuclear co‐operation with the Republic as a lever to press for political change and to secure South Africa's adherence to the NPT. The Republic has however steadfastly declined to sign the NPT. although it has made clear on several occasions that it will not allow its uranium sales to be used to increase the number of nuclear‐weapon states. South Africa's refusal to sign the NPT...


Opportunities provided by genetic testing is now an unquestionably principal role in today's patient care. The emergence of next generation DNA sequencing (NGS) techniques has brought paradigm shift in gene diagnostics. Even recently, the diagnosis of various endocrine diseases consisted of routine physical examinations, laboratory and imaging tests, and it was only possi-ble to identify the genetic background of the well-defined monogenic diseases. The launching of high-throughput next generation sequencing platforms has fundamentally changed the clinical practice. Genetic tests are becoming more prominent and the diagnostic power of results is increasingly important. Numerous endocrine diseases have complex multifactorial etiology, therefore a cost-effective sequencing of multigene panels, or even the whole exom is required to complete the routine clinical tests. There are many examples of successful use of the NGS strategy in clinical practice and in case of differential-diagnostical problems, such as: multifactorial endocrinopathies, overlapping phenotypes, endocrine tumors, or in prenatal application regarding to screening of endocrine-related sex chromosome disorders. Using next generation technology, in addition to providing a more reliable diagnosis, we can reveal the pathogenet-ic background of complex endocrine syndromes in more details, highlight disease-modifying gene variants, and find new therapeutic targets as well.


Metastable atom electron spectroscopy and ultraviolet photoelectron spectroscopy were used to characterize orientation of bisazomethine dye molecules (DE2) in thin films deposited on graphite and ITO. We found that the molecular orientation of DE2 in multilayers is largely different on these substrates. On graphite, the molecules lie flat in a monolayer and become standing up with increasing the film thickness, while on ITO they lie nearly flat independent of the film thickness.

This paper considers a logical framework for modelling security policies for information systems. Epistemic, deontic and temporal logics can respectively be used to express what an agent knows or believes, what an agent is permitted or forbidden to know or do, and the dynamic progress of a system over time. In modelling a security policy for a practical system, one may need to combine these logical notions to express statements of the policy, so a combination of logics is considered. We investigate the issues regarding techniques for combining logics, approaches to formalizing security policies based on a combined logic, and strategies applied for reasoning about the security properties required to be satisfied by a policy. Several possible future research directions under this logical framework are discussed.


Global climate change and it's environmental, political, and economic effects have been recognized as one of the most interconnected challenges faced by humanity today.

This report concludes with several mitigation strategies that can aid and be implemented to reduce the devastating effects of climate change.


Abstract Research has described the importance of orality at work and in everyday life but little agreement currently exists on how to theorize modern orality. This study explores how young adult literacy learners thought about and employed their textual (print) literacy within the oral contexts of their lives. We interviewed 88 mainly unemployed young persons undertaking literacy training to assess how their literacy fitted within their everyday lives, exploring their learning, employment, motivation, persistence, barriers to learning, and power dynamics. Respondents saw their textual literacy as situated within a matrix of everyday interpersonal communication more than as stand-alone functional skills, describing how literacy integrates with oral-experiential lifeworlds such as at work. Empirical evidence was provided to support the recent work of scholars who are building theory in the text–orality nexus. This study provides insights into the oral world of people with liminal (threshold) textual literacy; since such individuals are necessarily more oral than literate in their everyday life experience, they provide unique insights into how their orality intersects with use of textual information.


The philosopher Frane Petriċ (Franciscus Patricius, Francesco Patrizi 1529–1597), particularly in his major works, Discussiones peripateticae and Nova de universis philosophia, devoted a significant part of his studies in ontology and cosmology to a highly original study of light and of time, two of the same concepts that play such an important part in Einstein's paper of 1905, "the electrodynamics of moving bodies". By juxtaposing these concepts in the two thinkers, it becomes clear that there is an affinity between the concepts in each of the thinker's systems. For patricius, as for Einstein, light has a unique, unchanging function in the universe. And in his analysis of time and related concepts such as duration, patricius developed a conceptual structure dynamic enough to find consistency with Einstein's analysis of time and of simultaneity.


In this paper, a lifetime of Photovoltaics PV is studied based on the evaluation of the reliability of the DC microgrid. The analysis has a comprehensive consideration of the elements of the inverter and converter composed of a renewable energy system and its process during bad weather as a supplementary measure for the intermittent output of renewable energy sources connected to the DC microgrid. A battery and a boost converter for the battery were used to keep the voltage constant. The output of the battery varies according to the output fluctuation of the renewable energy source. At this time, the life analysis result of the switching devices that are used in the boost converter is introduced. To prevent system downtime and increase maintenance costs due to converter failures connected to the battery, a converter life analysis is required. Considering that the main failure mechanism of switching devices used in converters is thermal stress, and power loss due to thermal stress. Based on the above, the lifetime characteristics of semiconductor devices are analyzed. The main contribution of this work is  conducting the lifetime analysis of solar energy system that is used in the DC microgrid with different weather conditions

It is attempted to show that the Stieltjes-moment-theory provides a practical and a reasonably accurate method for calculating the widths of molecular resonances. The method seems to possess a number of advantages for molecular applications, since it avoids the explicit construction of continuum wavefunctions. It is very simple to implement the technique numerically, because it requires only existing bound-state electronic structure codes. Through the use of configuration interaction techniques, many-electron correlation and polarization effects can be included in the description of both the resonance and the non-resonant background continuum. To illustrate the utility and the accuracy of the Stieltjes-moment-theory technique, used in conjunction with configuration interaction (CI) wave functions, recent applications to the /sup 1/..sigma../sub u/(1sigma/sub u/ 2sigma/sub g/) autoionizing resonance state of H/sub 2/ and the well known /sup 2/PI/sub g/ state of N/sub 2//sup -/ are discussed. The choices of the one-electron basis sets and the types of many-electron configurations appropriate for these two cases are described. Also, guidelines for the selection of the projection operators defining the resonant and non-resonant subspaces in the case of both Feshbach and shape-resonances are given. The numerical results indicate that the Stieltjes-moment-theory technique, which employs L/sup 2/ basis functions exclusively, producesmore » as accurate resonance parameters as can be extracted from direct electron-molecule scattering calculations, provided approximately the same approximations are used to describe important physical effects such as target polarization. Furthermore the method provides sufficiently accurate fixed-nuclei electronic resonance parameters to be used in ab initio calculation of resonant vibrational excitation cross sections. (WHK)« less


A token-based method for recursively estimating optical flow from a noisy image sequence is presented. Motion characteristics of the perspective projection of a 3D moving object are analyzed and a dynamic model is built. The recursive solution is achieved through an iterated extended Kalman filter and two schemes for the velocity propagation of match points are discussed. Experimental results indicate that this method, which requires a long image sequence but rather few match points, is efficient and robust even in very poor conditions.<<ETX>>


Language is the most essential feature of any work of art, which is necessary for the communication of meaning. Language could come in different forms: oral, written, sign and material. Whatever form it takes, it helps in the continual promotion and reconstruction of sociocultural identity. Using Afolayan's The Figurine (Araromire) as a point of reference, this article examines the place and implications of multilingualism, and the socio-cultural impact on Nigerians, and Africans at large. It also examines how the various forms of language can aid the shaping of the cultural identity of the people towards the preservation of valued culture for the present and future generations. Lastly, the article suggests that Nigerian films and filmmakers/producers should be seen and employed as cultural ambassadors of Nigeria to the outside world. Keywords : Language, Multilingualism, The Figurine , Cultural ambassadors, Filmmakers


The invention discloses a direct reduction process for producing spongy iron from CH4-rich coal gas, which comprises the following steps: a, inputting CH4-rich coal gas subjected to pressure regulation and gas-based shaft furnace top gas sequentially subjected to cooling, dust removal and pressurization treatment into an outer converter, supplementing steam taken as modification reaction oxidizer of CH4 into the outer converter, and enabling CH4, H2O and CO2 in the outer converter to be subjected to modification reaction under the effect of a catalyst to generate high-temperature reducing coal gas mainly containing CO and H2; and b, inputting the high-temperature reducing coal gas generated in the outer converter into a gas-based shaft furnace to directly reduce iron ores to generate spongy iron. According to the invention, CO2 in the top gas is fully utilized to generate CO so as to provide reducing gas, thereby reducing the discharge of CO2, omitting the coal gas decarburization procedure and ensuring that the process is simple; and CH4 in the raw gas is subjected to thorough reaction, and the temperature of the high-temperature reducing coal gas is controlled at 850 DEG C, thereby realizing that the utilization efficiency of the raw gas is high, and avoiding the problems of blockage and shaft furnace cementation caused by a great amount of carbon precipitate of CH4 at high temperature.


Libraries offer a diverse array of information resources‐both in electronic and print formats. The challenge for libraries is to provide access to all of these resources in an integrated and user‐friendly way. MAP (Millennium AccessPlus) meets this challenge with three different functions: WebBridge, MetaFind, and WebAccess Management. Together, these tools provide libraries with the ability to manage and control access to all of their information resources by providing smart linking, multi‐protocol meta‐searching, and authentication.


The virtual action as a variational equation is considered to hold as an axiom in mechanics. In this thesis time finite element methods are developed by discretizing the principle of virtual action and related variational principles. Using the Legendre–Fenchel transform, multi-field formulations are induced from the principle of virtual action. For mechanical systems described in minimal coordinates, the infinite dimensional variational formulations are discretized by introducing temporal shape functions. Such a discretization reduces a variational equation to a set of nonlinear equations approximating the dynamical behavior of a mechanical system. For a single-field formulation these nonlinear equations are equivalent to a time stepping algorithm. The various finite element methods are compared with respect to convergence behavior for three different mechanical systems.


Phytoplankton are micro- organisms which does not have any low mortuary oxygen floating water surface and move with water current. Phytoplankton are photosynthetic autotrophic which constitute the primary producers tropic level of oceanic water. They very high productivity and key of whole marine ecosystem .The phytoplankton includes all the plant-like organisms plant-like in the sense that they are autotrophic and contribute directly to the food available in the surface waters by building up their protoplasm and food reserves directly from carbon dioxide and salts in solution in the sea. Zooplanktons are planktonic free-floating animals in fresh and marine aquatic systems, and are the major consumers of the organisms in the microbial food web. This book help to study the Plankton Culture and identification methods.


The Global Change program for the Sonoran Desert just began in March 1992. Currently, two projects are being directly funded by the National Park Service and we are coordinating with research of other agencies. One thrust of the program is to understand the effect of climate on species growth, abundances and distribution. This will be done using a number of methods. One is growth ring analysis of conifers on mountain ranges in and bordering the Sonoran Desert. Another study will relate the USGS Desert Laboratory data base on plant species distributions to a mesoscale climate model. Other programs that we are coordinating with include a USGS Desert Laboratory project to study long term changes in plant communities of the southwest using a comparison of photos from the early 1930s, early 1960s and early 1990s. Other agencies have active global climate research at The University of Arizona and we are working to coordinate the NPS program with these at the investigator level through participation in a university-wide Global Change Committee.

Carbon fibres (Cf) are one of the most important reinforced materials for ceramic matrix composites such as Cf - SiC composites and they are generally sought for high temperature applications in as space application, nuclear reactor and automobile industries. But the major problem arise when Cf reinforced composites exposed to high temperature in an oxidizing environment, Cf react with oxygen and burnt away. In present work, we have studied the effect of silica (SiO2) coating as a protective coating on Cf for the Cf / SiC composites. The silica solution prepared by the sol-gel process and coating on Cf is done by dip coating technique with varying the withdrawing speed i.e. 2, 5, 8 mm/s with fixed dipping cycle (3 Nos.). The uniform silica coating on the Cf is shown by the Scanning Electron Microscope (SEM) analysis. The tensile test shows the increase in tensile strength with respect to increase in withdrawing speed. The isothermal oxidation analysis confirmed enhancement of oxidation resistance of silic...


When subcooled water in accumulator tanks is injected during a loss-of-coolant accident of a pressurized water reactor, violent condensation takes place in cold legs because of direct contact of steam with water. A flow model based on the multifluid model of the two-phase flow has been developed to formulate the condensation and mixing processes in the injection region. The measured liquid film temperature and pressure profiles in the injection region have been explained quantitatively with the model which includes (a) drop generation arising from atomization of injected water, (b) condensation of steam on the drops, (c) flow contraction resulting from the formation of the dead water region, and (d) deposition of the drops. The calculated results show that the condensation rate depends mostly on the drop diameter generated near the water injection nozzle and the maximum drop mass fraction in the injection region. The present model can predict the effect of inlet thermal-hydraulic conditions on the condens...

The absorption properties of the well-known coumarin dyes are evaluated at the 436 nm g line for PMMA bilayer systems. Their properties are compared with those of other commercial products. The main requirements to be met are : good solubility in PMMA solutions, an absorption spectrum adapted to bilayer processes and thermal stability. Several azo dyes have been selected from among a large number of compounds and are proposed as an advantageous alternative to coumarin dyes. The implementation of one of these selected dyes in a bilayer process is given as an example. A good dimensional control is obtained for 1 μm lines over critical topographies.


We have read with great interest the report, recently appeared in the Journal, by Fazakas et al. [1], who described a case of a 65-year-old woman presenting with coexisting multicentric plasmacytic Castelman disease (CD) and polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes (POEMS) syndrome. Virological examinations resulted negative for either human immunodeficiency virus (HIV) serology or human herpesvirus-8 (HHV-8) DNA sequences by polymerase chain reaction (PCR). On the other hand, DNA sequences of human herpesvirus-6 (HHV-6) were found to be present in both the blood and lymph node samples of the patient, so the authors concluded that the modulation of immune functions induced by HHV-6 may facilitate polyclonal plasma cell hyperplasia and might have been potentially responsible for the development of CD and POEMS syndrome in the described case. On the other hand, the presence of HHV-6 DNA in a few HIV-negative and HHV-8 negative CD cases have already been reported [2]. However, we wish to make some comments on these issues. Even if several studies have suggested an association between HHV-6 infection and lymphoproliferative disorders, based upon the disclosure of HHV-6 DNA sequences in neoplastic lymph node tissues [3–5], the wider use of immunohistochemical examinations has subsequently shown that the expression of latent and lytic viral antigens is restricted to reactive cells, while invariably absent in neoplastic cells, in the cases so far examined, arguing against a direct major role of HHV-6 in lymphoid malignant transformation [6]. Nevertheless, an indirect role of HHV-6-infected reactive cells in modulating and triggering the proliferation of lymphocytes, by modifications of lymph node microenvironment cannot be excluded [6]. In the case reported by Fazakas et al., no information about HHV-6 immunohistochemical analyses on lymph node tissue were provided, so that the evidence regarding a potential pathogenetic role of HHV-6 are, unfortunately, only based upon molecular examinations. Furthermore, the authors based their conclusions on the positive results of a qualitative nested-PCR analysis of the lymph node tissue and of a single blood sample. Neither HHV-6 variant characterization nor HHV-6 viral load quantitation have been performed [7,8]. This latter analysis would have been of great interest, in order to exclude the phenomenon of HHV-6 chromosomal integration (CIHHV-6), which is a unique form of HHV-6 latency, characterized by integration of apparently whole-genome length HHV-6 sequences into host chromosomes [9,10]. CIHHV-6 has a prevalence ranging from 0.21 to 3% either in healthy subjects or in transplant and leukemic patients from different geographical areas and, even if a range of viral genes may be transcribed, there is no evidence, to date, of active viral replication and pathogenicity in case of CIHHV-6, despite the high HHV-6 load found in every tissue or body fluids analyzed [11,12].


In the context of the economic and political uncertainty associated with the 2019-nCoV pandemic, it is necessary to determine the socio-psychological factors involved in the transformation of the behavior of insurance consumers under the influence of a biogenic threat. This study measures financial anxiety and its impact on the insurance behavior of Russian citizens. The correlation, comparative, and regression analyses of the financial anxiety of Russian citizens cover three stages of observation: before the start of the 2019 nCoV pandemic ("FA up to 19 nCoV; N = 766), during the period of quarantine measures announced in Russia in March 2020 ("FA 19-nCoV-1"; N = 856), and after the relaxation of quarantine measures at the end of April 2020 ("FA 19-nCoV-2"; N = 963).Psychological analysis data were obtained from the online survey "Financial anxiety (in the context of insurance)". The questionnaire is psychometrically reliable and easy to use. It includes five measurement scales: MR1—Physical manifestations of financial incentive anxiety, MR2—With money shortages and financial uncertainty, MR3—The value of insurance coverage, MP4—Financial Confidence, and MR5—Perception of insurance and investment risks. It was found that Russian citizens consider it important to have insurance coverage for a "rainy day", and they showed confidence in the insurance market during the biogenic crisis. However, unfortunately, during the 19-nCoV-1 and 19-nCoV-2 periods, Russian citizens did not feel financially secure, unlike in the period before 19-nCoV. Women showed high scores for physical manifestations of financial anxiety and low financial confidence in the future, in contrast to men, regardless of the observation period.

Summary form only given. New routes to obtain Keggin structure phosphomolybdic heteropolyacid aniones doped polypyrrole were elaborated, and its spectral and electrochemical characteristics investigated. Pyrrole was found to be oxidized by non-aqueous phosphomolybdenic acid and its salts in CH/sub 3/CN, that cause polymerization. As was revealed, phosphomolybdic heteropoly acid anions are capable of catalysing pyrrole electrochemical polymerization. The chemicaly and electrochemicaly produced polypyrrole was shown to be doped by heteropolyanions of the structure H/sub (3+k)=n/Pmo/sub 12/O/sub 40'/ where (0< k< 6), (0< n< 3). The charge-discharge characteristics of the resulting material were studied by CVA and chroncamperometry techniques. The results evidence involvement heteropolyanions dopants in the redox conversions of the material. The electrochemical oxidation of a variety of organic substrates (naphtalene, antracene, tetramethylhydroquinone, hydroquinone, 2,6-ditertbutylphenol, tri-p-tolylamine, benzylalcohol etc.) on a platinum electrode coated with a heteropoly anions doped polypyrrole was studied. The electrocatalytic effect of anodic tetra methylhydroquinone, hydroquinone and tri-p-tolylamine oxidation on such electrodes was revealed. This makes it possible to effect oxidation of the above compounds on an electrode covered with heteropolyanions doped polypyrrole at lower potentials and a higher current density compered to perchlorate-anions doped polypyrrole electrode and an unmodified Pt electrode. The effect found is ascribed to the electrocatalytic action of heteropolyacid anions in the course of anodic oxidation.


There are many movies performed, from low until high rating, which is the movie maybe popular or not popular. If many people watched that movie maybe it is popular, in other hand if a movie is watched by a little person so that movie can called as not popular movie. Popularity of movie can determined by several factors, such as likes, ratings, comments, etc. To determine popular or not popular of movie based on features, will use two classification methods that is logistic regression and Support Vector Machine (SVM). In this research, the data are Conventional and Social Media Movies Dataset 2014 and 2015. To get the best model and without ignoring the principle of parsimony, will do feature selection. The selected features are genre, sentiment, likes, and comments. That features will be used to classify the popularity of movies. This research used two classification methods namely logistic regression and Support Vector Machine (SVM). When used logistic regression, the accuracy is 77.29%, while used SVM the accuracy is 83.78%. Based on the accuracy of both methods, it is found that SVM gives the highest accuracy for CSM dataset. The highest accuracy is obtained from the SVM method with non-stratified holdout training-testing strategy.

Dvořak's compositions created and spread around 1900, especially his opera Rusalka, touch on the aesthetic problem of rapport between the arts. What impact had the literary atmosphere here, especially on the librettist Jaroslav Kvapil? His multifaceted career, impregnated by the principles of the 'parnassians' and symbolists, explains the eclecticism of his work – influenced by Maeterlinck and Schopenhauer, but also by Kytice by Erben.The poetic works of the young Kvapil, such as his Rusalka, document his links to an ideal of communication without words, which, disordered by its nature, is a type of non articulated language.

This study aims to reveal the independent auditor's way in applying personal ethics value and profession ethics code to the performance of auditing in two points between the right and wrong or similar to not stuck in the choices that destructive. Two cultures of Bali, Kain Poleng and Mulat Sarira, are used as a perspective to reveal how the auditors working in the good and bad spectrum as described by Kain Poleng which is still showed the identity. This study used qualitative approach with personal as a tool of analysis through data reduction and reflection methods. Triangulation data source was conducted on cases relating to the ethics auditor in order to get sufficient understanding. The interview result shows that the auditor who internalizes the concept of Kain Poleng and Mulat Sarira is stronger to face temptation from the outside because they are afraid of God reprisal which resulted in the application of responsible profession ethics code.


We propose a qualitative analysis of a recent fractional-order COVID-19 model. We start by showing that the model is mathematically and biologically well posed. Then, we give a proof on the global stability of the disease free equilibrium point. Finally, some numerical simulations are performed to ensure stability and convergence of the disease free equilibrium point.


The stereoselective synthesis of chiral terminal epoxides is of immense academic and industrial interest due to their utility as versatile starting materials as well as chiral intermediates. In this study, new dinuclear chiral Co (salen) complexes bearing gallium-, indium- and tallium-chloride have been synthesized and characterized. The mass and EXAFS spectra provided the direct evidence of formation of dinuclear complex. Their catalytic activity and selectivity have been demonstrated for the asymmetric ring opening of various terminal epoxides having ether or ester groups by hydrolytic kinetic resolution technology. The easily prepared dimeric complexes exhibited very high enantioselectivity for the asymmetric ring opening of epoxides with H2O nucleophile, providing enantiomerically enriched terminal epoxides (> 99% ee). The dimeric structured chiral salen showed remarkably enhanced reactivity and may be employed substantially lower loadings than its monomeric analogues. The system described in this work is very efficient for the synthesis of chiral epoxide and 1,2-diol intermediates


Ingredients of urine proteins are complex, and different types of urinary proteins are usually associated with different diseases. Light chain proteins are related to neoplastic diseases, which might be misdiagnosed as nephropathia. Accurate detection of urine light chain proteins in
 urine is very important for early diagnosis of multiple myeloma and other diseases. Traditional methods for detecting urinary light chain proteins are of low sensitivities, complex processes and high costs. Surface plasmon resonance (SPR) is a sensitive, real-time and label-free method which
 is suitable for studying protein-molecule interactions. In this paper, SPR methods were used to detect kappa light chain proteins through direct assay method. Kappa light chain protein antibodies with a pH value of 5.0 were successfully immobilized to the sensor chip in one channel while another
 was used as a reference channel. Detection limit of kappa light chain proteins was estimated to be 0.1 μg/mL through direct assay method in standard solution. Healthy and patient human urine samples were also tested, which showed different SPR response signals. It indicated that
 SPR could be used as a fast and sensitive method in quantitative detection of urinary kappa proteins.


Gastric cancer is one of the most common cancers in the world. Delayed
 diagnosis is the most common cause of death in patients. Long noncoding RNAs
 (lncRNAs) are a group of non-coding RNAs that are effective in the incidence
 of cancers. Studies in different cancers determined HOTAIR as an important
 lncRNA in tumorigenesis. In gastric cancer, the function of HOTAIR in the
 initiation and progression of cancer seems to be crucial. In this study, we
 confirmed the significant differential expression of HOTAIR between gastric
 tumors and normal tissues in different datasets. In the following, the
 regulatory function of HOTAIR and its interaction with miRNAs in development
 of gastric cancer was analyzed. Our analysis determined that the
 upregulation of HOTAIR is essential to different pathways associated with
 the progression of gastric cancer. Further analysis determined numerous
 miRNAs as potential targets for HOTAIR. Among them, we demonstrated miR-1 as
 a significant miRNA with negative correlation with HOTAIR in gastric tumors.
 Validation analysis determined that HOTAIR is a target of cisplatin as a
 common chemotherapy drug. Eventually, the effect of cisplatin on the
 expression of HOTAIR and its potential target, miR-1, was checked by an in
 vitro study. Cisplatin treatment on the gastric cancer cell line showed that
 there is a significant negative correlation between the downregulation of
 HOTAIR and the upregulation of miR-1 in treated cells. In conclusion,
 comprehensive in silico analysis and experimental study provided evidence
 for the importance of the HOTAIR/miR-1 axis as potential diagnostic and
 treatment strategies for gastric cancer.


Twelfth Night was the first major production of a comedy at the Royal Shakespeare Company's new Courtyard Theatre, its limited season of six weeks representing an interlude in the Histories Cycle. Directed by Neil Bartlett, the production set out to evince a ''world of aristocratic confusion'' in which the fluid boundaries of gender identity would be brought to the fore. Bartlett's previous theatre work has been described as challenging and thought-provoking, and his Twelfth Night is no different in this respect. Something the audience is likely to think about afterwards, though, is the cost of his innovative approach to a much-loved play. The challenging of expectations begins almost before the performance. Taking their seats in the Courtyard, the audience becomes aware of silent figures on the dark stage. Downstage, an aproned female servant kneels and sweeps the dusty space; upstage, an aristocratic man dons a suit from a rack of clothes. Both seem to be assuming their roles, preparing for the performance. The black-and-white dress of servant and master evokes the stark class distinctions of an Edwardian country house, but the extended preparation scene suggests that the boundaries of class and gender are not yet fixed. The production promises to explore the idea, now commonplace in some strands of literary criticism but rarely played out so explicitly on stage, that class and gender are a theatrical performance. The busy preparation is for the arrival of Orsino's houseguests, who will smile politely as Orsino (Jason Merrells) goes into protracted raptures at the piano playing of Feste (James Clyde). Feste frames the performance. Leaning into the microphone on his baby grand he announces*in the gravelly voice of a disenchanted cabaret performer*''Twelfth Night''*and, after a pause*''Or, What You Will''. This meta-theatrical touch (he will later announce ''Intermission'') elicits laughter from the audience, but also heightens the mood of self-conscious performance. That ''Cesario'' is the only other single word spoken into the microphone in this way emphasizes the greatest instance of theatrical pretence in Twelfth Night: Viola's five-act attempt to ''Conceal me what I am'' and ''disguise'' herself ''as an eunuch'' (1.2.49 52). Bartlett's production, with its repeated motifs of dressing, undressing, mirroring and observing, extends beyond Viola to all of the characters the idea (suggested in the programme) that ''identities can be put on and taken off like theatrical costume''. Orsino dresses himself on stage; his guests don raincoats from the same clothes rail to become sailors in the storm; Sir Toby Belch is first seen putting on his plus-fours in front of his mirror; and Malvolio and Olivia become steadily more unbuttoned as the play progresses. All repeatedly check their reflections, peering into and frantically spinning the full-length mirrors that dot the stage. This backstage atmosphere is intensified when, at the interval, a square of yellow bulbs lights up around the edges of the thrust stage and across the back wall, suggesting a vast dressing room mirror. The mirrors on stage are at once reflective and transparent: the audience looks through one to watch Viola, as Cesario, soliloquizing to her reflection. In a production in which characters anxiously scrutinize both their own performances and those of others, this double-sided mirror is a pertinent symbol.

In this paper, an active vibration control with the use of an air-cell seat for passenger cars is investigated. The roles of the air-cell inserted between the polyurethane foam of the seat and seat cover are first to extend the seat's capability to adopt various shapes of human body and to improve the ride-comfort against road disturbances. The air-cell seat is modeled as a 1-d.o.r. spring-damper system. Because an exact modeling of the air-cell itself is alomost impossible, its dynamic characteristics are analyzed through experiments. A road-adaptive gain-scheduled sky-hook control for the air-cell seat system is proposed. The skyhook gains are scheduled in such a way that the acceleration level transmitted to human body on various road conditions is minimized. Simulations and experimental results are provided.


Steviol glycosides (SVglys) are a group of diterpenoids mainly present in the leaves of stevia (Stevia rebaudiana Bertoni). An experiment was conducted to find the functional role of SVglys compounds in stevia affected by drought stress. In this study, a liquid blend of SVglys (200 ppm) was sprayed on stevia plants grown in well-watered (90% field capacity) and drought-stress conditions (45% field capacity) and then the morphological traits and metabolites were evaluated. It was observed that leaf losses caused by drought stress were stopped through external application of SVglys and consequently the harvest index of stevia was increased. Metabolite analysis of stevia leaves showed that the total SVglys content was significantly decreased due to drought stress, but was compensated by external application of SVglys. Among the SVglys, Rebaudioside A responded more to external SVglys. A slight promotion in total antioxidant activity of stevia leaves was observed when external SVglys was applied. The glucose availability in stevia leaves was increased by external application of SVglys but only in well-watered plants. According to our findings, it can be concluded that in stevia, SVglys may have a positive function in drought stress tolerance by exerting a protective role under such conditions.

According to Oduaran (1996), war, hatred, bitterness, rivalries, carnage, conspiracy and treacherous plots are some of the most conspicuous alternative concepts and corollaries to the desirable and soothing of peace. Peace is desirable in creating the harmonious relationship needed to ensure meaningful sustainable development. Peace is considered a desirable goal for everyone. It is a great idea that the world had continued to dream about. Peace enables us develop in people a set of dynamics and purposeful attitudes which assist the beneficiaries to search for and uphold the value of justice and human rights. Hence, there has been frantic effort aimed at discerning the world and promoting world peace. On conflict, once it becomes either latent or open, attempts will be made to resolve it and there are many ways of resolving conflicts (Innocent, 2006). History teaches that when a conflict arrives at an open stage, there are usually alternatives to resolution. For instance, in African Traditional Religion in Ibibio culture, ayeiis a powerful symbol for conflict resolution and peace – building among parties affected. For Innocent, (2006) conflict resolution refers to a situation where different approaches are employed to address and resolve conflicts once and for all, the sources of conflict and in the process change the structure of conflict to that of peace. For Mitchel and Banks (1996), conflict resolution means: the outcome in which the issues in an existing conflict are satisfactorily dealt with through a solution that is mutually accepted to the parties, self – sustaining in the long run and productive of a new, positive relationship between parties that were previously hostile adversaries. In the light of these, it will not be wrong to say, there is a nexus between religion and culture in conflict prevention and peace-building. The methodology is a descriptive phenomenology. This is because not much empirical studies have been carried out on the issue. The study reveals that different religions have ethical standards and bequeath principles of good behaviour to their adherents. Thus, when religious and ethical values of culture are well harnessed and disseminated in an existing culture, an enabling ground would be put in place for conflict prevention and peace-building. The study concluded that Religion and Culture are indispensable in any society for conflict prevention and peace building in any given environment.


The evaluation is to be undertaken to look at the achievements of the program, one of which is to see a successful image is built. But the practition PR still rule out the importance of evaluations with it. The purpose of this research was to evaluate the development image of Coca-Cola Matil Indonesia Central Java (CCAI-CJ) through the implementation of Coke Farm CSR activities among external stakeholders involved directly. The theory being used, namely the theory of development of CSR to image building. The model of evaluation is used Context, Input, Process, Product (CIPP). Qualitative an quantitative data collection techniques are performed using indepth interviews to one informant, namely Public Relations (PR) of CCAI-CJ. The research shows PR CCAI-CJ hasn't been able to take advantage of the program for the development of a Coke Farm image. From the results of the assessment effectiveness to assess CIPP indicator in each category receives a total value of about 3 indicating that CSR Coke Farm ineffective for development CCAI-CJ image. In carrying out Coke Farm, PR did not run all the stages that must be done within the CSR program. With the management of Coke Farm that is less than maximum, then it is not able to build a positive image of CCAI-CJ through Coke Farm. It is proven by the results of a questionnaire that show of social image obtained through the program of Coke Farm is to tend negative. For eco-friendly image of CCAI-CJ is also included into the category tends to be negative. The attitude of respondents towards CCAI-CJ shows many negative results. Social image and eco-friendly image obtained from the respondent's assessment regarding the social benefits of Coke Farm. Coke Farm considered hasn's been able to deliver the benefits of the respondent.


An end-to-end conversational speech synthesis that enables a flexible control of emotional states defined over emotion dimensions is proposed. The Tacotron 2 architecture is extended so as to receive the emotion dimensions as input. The model is first pre-trained using a large-scale spontaneous speech corpus, then fine-tuned using a natural dialogue speech corpus with manually annotated perceived emotion in a form of pleasantness and arousal. Since the corpus for pre-training does not have emotion information, we examined two pre-training & fine-tuning strategies, and showed that the one applying an emotion dimension estimator before the pre-training was superior. The result of subjective evaluation for the emotion controllability showed a correlation of $R$ = 0.48 for pleasantness and $R$ = 0.78 for arousal between given and perceived emotional state, indicating the effectiveness of the proposed conversational speech synthesis with emotion control.


Due to the increased frequency of multidrug-resistant bacterial strains isolated from infectious processes, a constant analysis of their sensitivities to the antibiotics currently used in therapy is required. The aim was to follow the evolution of the resistance phenomena for Pseudomonas aeruginosa strains isolated from infections. Pseudomonas aeruginosa is a current concern for clinicians and epidemiologists due to the intrinsic resistance to several classes of antibiotics, acquiring resistance and limiting therapeutic actions. It is a microorganism of major importance in the nosocomial infections developed both in the human and veterinary spaces. The tests were part of a more extensive study which was aimed at the correlating, identifying common resistance profile of P. aeruginosa strains of human and animal originated. Considering the pathogenic action of this bacterial species both for humans and animals, the data obtained can support the establishment of a mutual strategy to prevent and combat the action of strains having multiple resistance to antibiotics. Efflux transporters have a considerable role in the multidrug resistance (MDR) of P. aeruginosa, an important nosocomial pathogen. The lack of some antibiotics, active towards P. aeruginosa, makes the control of infection the most important measure against the MDRP. aeruginosa strains. The study batch included strains of P. aeruginosa, out of which only the antibiotic-resistant strains, 61 strains respectively, were selected for the phenotypic characterization in fluoroquinolones.

Production of digital images from cameras, mobile phones, camcorders, video films and scanned images has increased exponentially in the past decade. Increasing number of digital devices have influenced human to an extent of taking the same scenes in multiple views. Commercial Organizations, Agencies and Educational Institutions conduct events round the year and the image acquisition activity through the digital devices installed at the event venues is predominant in Universities and Colleges. It is evident that the cost of recording the events is negligible compared to the storage requirement over the years for future reference and inference. Thus the captured images must be preprocessed to avoid duplication and parsed for low-level processing such as noise removal, contrast enhancement and image sharpening. Few of the processed images can then be chosen based on the weights associated with the event sessions using midlevel processing techniques such as object detection and recognition. Further, the chosen images can be indexed, captioned to be maintained as an archive and stored in the databases to extend quick summary of events for preparing annual documents, editing magazines and departmental newsletters. This paper explores different data mining techniques namely classification and clustering to automatically group the images.


The competency-based approach, notwithstanding all its positive effects on education quality in general, cannot escape problems and difficulties. One of the principal problems is the problem of legal enforceability of the regulations at the local level. The third generation Federal State Educational Standards imply liberalization in the sphere of educational scope and procedures. From the perspectives of procedures, the principle problem of the competency-based approach is represented by its excessive focus on individual unsupervised activities of the students.


Recently, there has been increasing interest in Phyllanthus emblica due to its chemical composition and the potential health benefits. The present study was undertaken to investigate the effect of nanoparticles extracts of Phyllanthus emblica on diabetes, because nano-structured systems could promote sustained release of active constituents, reduce the required dose, low toxicity, decrease side effects, and improve activity. Therefore, the protective effect of P emblica-NPs was studied on type-II diabetes through determination of serum glucose levels, expression alterations of glycolytic and gluconeogenic genes, DNA damage and liverspecific antioxidant glutathione peroxidase (GPx) enzyme in diabetic rats induced by Streptozotocin (STZ). Our study showed that P emblica-NPs significantly decreased the blood glucose alterations in the expression of glycolytic and gluconeogenic genes, DNA damage and increased the activity of GPx. The results could be concluded that the nanoparticles of P. embelica extract increased the potential to be developed as an antidiabetic agent.


Between the fifties and sixties of the twentieth century, Ayfre Amedee, a Catholic priest, gave voice to an attempt of a spiritualist criticism of cinema, based on the thinking of Andre Bazin. Starting from a dimension strongly linked to phenomenology and through the experience of the comparison with neo-realism (especially Rossellini), Ayfre implemented the attempt to supplant the Real with a dimension that gives rise to a possible theological shift, where the image takes on a sacred constitution. In this sense, despite the peculiarities by which it is expressed, the experience of neo-realism becomes the model of a kind of cinema that offers a religious consciousness, without the materialist historicism of the Marxist readings so typical of Italian critics. This paper aims to propose a systematization of Ayfre's thinking within a problematic horizon that concerns the following questions: can the phenomenological dimension of cinema lead to the Real?And, if so, can the Real take on a double meaning of transcendence and incarnation of the Sacred, thereby problematizing in this ambiguous coexistence a possibility of consciousness in cinema?  And finally, what is the limit of this consciousness in the moment in which cinema, a phenomenologically concrete apparatus linked to the concreteness of the subjects' being in the world that it represents, wants to make the passage between Incarnation (phenomenology) and Transcendence (spiritualism) explicit and visible? The aim of this paper is to show that in the interpretation of cinema and in the films proposed by Ayfre, the cinematic language can be understood as a language characterized by a precise and replete – although sometimes ambiguous - dual consciousness: that of the religious phenomenon (cinema as a chance to show the potential of the incarnation of the sense of the sacred in the image),  and that of the sacred phenomenon (cinema as an expression of the otherness that refers to a further dimension and yet one that is virtually linked to the phenomenological present).


The relationship of maximal testosterone production to the amounts of cholesterol side-chain cleavage (P450scc), 17α-hydroxylase/C17-20 lyase (P45017α), and iron sulfur protein (ISP) reductase was determined in Leydig cells from four inbred strains of mice (RF/J, SWR/J, C3H/He, and DBA/ 2). The amounts of P450scc, P45017α, and ISP reductase were also determined in adrenal glands of the same mice. cAMP-stimulated testosterone production and P450scc protein were high in RF/J and SWR/J compared to C3H/He and DBA/2 Leydig cells. A significant correlation between the amount of this enzyme and the capacity for testosterone production was found (r = 0.89; P < 0.0005). ISP reductase was highest in RF/J, SWR/ J, and C3H/He Leydig cells, which are significantly different from DBA/2. No significant differences in the amount of P45017α in Leydig cells from the four strains could be detected, and neither ISP reductase nor P45017α correlated with testosterone production. To ascertain if tissue-specific factors affect t...


This work applies the equilibrium molecular dynamics simulation method to study a Lennard-Jones liquid
thin film suspended in the vapor and calculates diffusion coefficients by Green-Kubo equation derived from
Einstein relationship. As a preliminary test, the diffusion coefficients of the pure argon fluid are calculated by
equilibrium molecular dynamics simulation. It is found that the diffusion coefficients increase with decreasing
the density and increasing the temperature. When both argon liquid and vapor phases are present, the effects
of the system temperature on the diffusion coefficient are investigated. It can be seen that the diffusion
coefficient significantly increases with the temperature of the system.


This paper introduces the concept of Dempster-Shafer fuzzy soft sets combined Dempster-Shafer theory and fuzzy soft sets. We study the FUSE operation on both Dempster-Shafer fuzzy soft sets, and the relationship between incomplete fuzzy soft sets and D-S fuzzy soft sets. At last, we present a new method of evaluation based on Dempster-Shafer fuzzy soft sets and apply it into the information systems quality evaluating to illuminate the practicability and validity.


The pressure vessel is one of a large number of plant components for which stress analyses must be performed. A pressure vessel experiences mainly two types of stresses, primary stresses and secondary stresses. Primary stresses are because of pressure inside pressure vessel and secondary stresses are because of thermal loading. Thermal loading is considerable in a pressure vessel which handles hot fluid. Typically liquid metal reactors (LMR) have thermo-mechanical loadings. Analytically, induced stresses are calculated using pressure vessel theory or ASME codes. In this paper induced stresses are calculated using ANSYS coupled field analysis for thermo-mechanical loading. The results are then compared with analytical results. This work demonstrates usage of commercial FEA tool over analytical approach. Analytical solutions such as ASME and Japanese Code give empirical relationships to calculate thermal stress. Use of FEA tools is not very popular in pressure vessel industries. FEA of this kind of loading requires coupled field analysis. In the work ANSYS is used to perform coupled field analysis.


Efforts in using a surface interpolation technique to improve flat triangular facet models are shown. The authors performed RCS (radar cross section) calculations on a triangular faceted sphere, created a new sphere using the interpolation technique, and re-performed the RCS calculations. The original model was created with a uniform radius, ensuring that the RCS was as accurate as possible before interpolation. Increasing the patch resolution on the surface of the sphere results in an improved RCS calculation. The authors then performed the same process for an ogive-shaped object, for which the theoretical value is also well-defined. It can also be seen here that, if there is an area on the original model that is slightly incorrect, smoothing the model using the interpolation technique can result in values farther from those of theory. In addition, the range profile of an aircraft wing is examined before and after interpolation. It is evident that although the surface of the object has not changed significantly, there is a change in the range profile.<<ETX>>

Thyroid nodules are quite common with approximately 5% of the population, and approximately 10% of older individuals, having palpable thyroid nodules (Mazzaferri, 1993). Between 30 and 50% of people living in the United States and Europe have thyroid nodules noted on ultrasound examination. Fine-needle aspiration biopsy (FNAB) has become the mainstay of thyroid nodule evaluation. While the overall accuracy of FNAB is excellent, an indeterminate or suspicious biopsy can pose a diagnostic and management dilemma. Some of these issues are illustrated in the following patient vignettes.


Substitution, and reassociation of irregular sparse LU factorization can deliver up to 31% additional speedup over an existing state-of-the-art parallel FPGA implementation where further parallelization was deemed virtually impossible. The state-of-the-art implementation is already capable of delivering 3× acceleration over CPU-based sparse LU solvers. Sparse LU factorization is a well-known computational bottleneck in many existing scientific and engineering applications and is notoriously hard to parallelize due to inherent sequential dependencies in the computation graph. In this paper, we show how to break these alleged inherent dependencies using depth-limited substitution, and reassociation of the resulting computation. This is a work-parallelism tradeoff that is well-suited for implementation on FPGA-based token dataflow architectures. Such compute organizations are capable of fast parallel processing of large irregular graphs extracted from the sparse LU computation. We manage and control the growth in additional work due to substitution through careful selection of substitution depth. We exploit associativity in the generated graphs to restructure long compute chains into reduction trees.


In this paper, we present our study on building a Web graph for the Malaysian Web based on the crawling of Malaysian Web sites. Given the constructed Web graph, interesting characteristics have been studied, such as the in-degree, out-degree, the distribution of power law, bow-tie structure and the strongly-connected components (SCCs). Besides, more important insight could be obtained from analyzing the hyperlinks among the hosts. Similar to Web graph, host graph serves as an informative source for enhancing crawling and searching methodologies, predicting Web growth and for Web sociology study. To date, Web or host graphs have been built for the global Web and other nations. Hence, being a subset of the global Web, it would also be interesting to compare the characteristics of Malaysian host graph with the global Web and other nations'. This research outputs a Malaysian Web graph, a Malaysian host graph and studies on the characteristics of these graphs. The graphs portray characteristics that are consistent with the graphs created for other nations. There are irregularities to the graphs where it is discussed at length to justify to anomalies.

We have shown that some electromagnetic systems allow specific frequencies to satisfy special equivalent conditions to make use of a left hand material. We called these frequencies resonances because of their properties, similar to those solutions of the homogeneous Fredholm's equation for nuclear physics. But the process of information transmission requires not only the envoy of a limited number of frequencies but a very broad set of them. To answer the question of how we can use the knowledge of the resonances on a real system, we make use of the communication theory and the other properties, like the super-oscillating addition of functions and the mathematical deformation of the contour of the spectral representation of signals in order to create a set of frequency packs labeled with the final effect to optimize the information broadcast. In this paper we also suggest how we can preserve the convenience of this resonant point of view even when we cannot guaranty that the resonant conditions can be sustained permanently.


Summary L. monocytogenes (types 1, 2, 3, 4a, and 4b) produces a heterogenetic antigen demonstrable by hemagglutination test with suitable antisera. Sheep erythrocytes modified by this antigen are lysed in presence of (rabbit) antiserum and guinea pig complement. Antibodies against this antigen are present in certain L. monocytogenes and S. aureus (rabbit) antisera and can be removed by absorption with either L. monocytogenes (of all types), S. aureus, or B. subtilis. The findings may help to avoid a possible pitfall in interpretation of serologic tests for species specific L. monocytogenes antibodies.


The acquired immune system of mammals (such as humans, mice, rats, and cattle) is the most studied immune system. Taking a quick look at the 'tree of life' reveals that this intensely studied system belongs to a very small minority of taxa, the jawed vertebrates, raising the question: why did this system evolve when all other plants and animals survive without it? This work reviews some of the ways in which immune systems may interact with each other in the context of evolution, and in terms of host immunization to pathogens.


The catalytic activity of Pt1–xPdx nanoparticles supported on carbon nanotubes (CNTs) was evaluated for both the hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR) of polymer electrolyte membrane fuel cells (PEMFCs). Using a colloidal method, Pt1–xPdx/CNTs catalysts (x = 0, 0.46, 0.76, and 0.9) were prepared, and their physical and electrochemical characteristics were analyzed using a variety of characterization techniques, including XRD, TEM, energy dispersive spectrometer, cyclic voltammetry, and electrochemical impedance spectroscopy. Both Pt and Pd atoms formed a continuous solid solution and thus were randomly mixed in Pt1–xPdx nanoparticles. Due to the high hydrogen absorption of Pd, the use of Pd in the catalyst provided an advantage for HOR but a disadvantage for ORR. The Pt0.53Pd0.47/CNTs catalyst in the anode and cathode showed the best cell performance of PEMFCs.


An isolate of Metarhizium anisopliae obtained from the white grub, Holotrichia titanis was tested. It showed a great pathogenicity to infect the white grub, H. parallela . Applying to soil with the conidia at 20×10 6~2.5×10 6 spores/g in the laboratory on the grub indicated a 100% infect ivity and the velocity of death was connected with the spores concentration of the pathogen.


The continuing proliferation of data science these days is causing organizations to reassess their workforce demands. Simultaneously, it is unclear what types of job roles, knowledge, skills, and abilities make up this field and how they differ. This ambiguity is generating a misleading myth around the Data Scientist's role. Against this background, this paper attempts to provide clarity about the heterogeneous nature of job roles required in the field of data science by processing 25,104 job advertisements published at the online job platforms Indeed, Monster, and Glassdoor. We propose a text mining approach combining topic modeling, clustering, and expert assessment. Therefore, we identify and characterize six job roles in data science that are in a request by organizations, described by topics classified in three major knowledge domains. An understanding of job roles in data science can help organizations in acquiring and cultivating job roles to leverage data science effectively.


Over 300 chemicals are designed as volatile organic compounds (VOCs) by the U.S. Environmental Protection Agency and most of them are highly toxic/carcinogenic substances that contribute to photochemical smog, global warming and so on. Therefore, VOCs are carefully regulated and different technologies have been developed to control their release to the atmosphere [1]. Catalytic oxidation is one of the most widely used techniques to control VOCs emissions at relatively low temperatures: it is less fuel intensive compared to thermal oxidation and it is highly versatile with the possibility to treat waste streams with different VOC concentrations and effluent flow rates [2]. It is generally accepted that the oxidation of VOCs over transition metal oxides, such as CuOCeO2 systems, occurs according to a Mars-van Krevelen type mechanism and proceed through lattice oxygen (nucleophilic attack) of the solid catalysts [3]. Therefore, the molecular oxygen is only required to reoxidize the reduced catalyst surface [4]. The redox activity of CuO-CeO2 catalysts is created by the ability to reduce and reoxidize both CuO and CeO2, which is enhanced by a strong interaction between these phases. Indeed, CuO-CeO2 is a more efficient catalyst for VOC total oxidation than the corresponding single metal oxides. This means that a synergistic effect between CuO and CeO2 can be observed using a MvK model to describe the kinetic data. In this work, several CuO-CeO2 catalysts with different Cu/Ce contents (denoted hereafter as CuxCe1-x where x indicates the Cu/Cu+Ce atomic ratio) have been synthesized by the solution combustion synthesis (SCS) and their catalytic activity has been examined in the total oxidation of ethylene as probe molecule. The prepared catalysts have been characterized by complementary techniques, including powder XRD, FE-SEM, N2 physisorption at -196 °C, H2TPR, XPS and IR spectroscopy. The CuxCe1-x catalysts have specific surface areas and total pore volumes in the range of 34-73 m 2 g -1 and 0.04-0.25 cm 3 g -1 , respectively. The largest surface area and pore volume values are observed for the Cu0.15Ce0.85 catalyst, whereas further increase of Cu content leads to worse values of textural properties, in agreement with previous studies. The specific surface areas for pure CeO2 and CuO are 69 m 2 XXXVIII Meeting of the Italian Section of the Combustion Institute g -1 and 4 m 2 g -1 , respectively. XRD patterns have shown that a cubic fluorite lattice structure of CeO2 (Fm3m symmetry) appear with all samples, as well as reflections of the CuO phase occur in the addition to those of ceria, as the increase of copper leads to the formation of bulk CuO particles. Figure 1 shows a representative FESEM image of the CuxCe1-x catalysts, in which is possible to observe relatively uniform agglomerates of particles (diameter of ca. 100-150 nm). Figure 1. FE-SEM image of the Cu0.6Ce0.4 catalyst. The oxidation activity of CuxCe1-x catalysts has been evaluated in the total oxidation of ethylene with a gas hourly space velocity of 19100 h −1 and a W/F value of 0.03 g h l −1 . The conversion of ethylene to CO2 as function of temperature is shown in Figure 2. All the prepared catalysts display positive ethylene conversion trends for an increasing reaction temperature. However, different conversion values can be observed. The most active catalyst is Cu0.6Ce0.4 and complete oxidation of ethylene to CO2 occurs at ca. 450 °C. Further increase of Cu content diminishes the catalytic activity. The lowest ethylene conversion is achieved for pure CeO2. As a whole, CuxCe1-x catalysts show better activities compared to pure CuO and CeO2 likely due to their easier reducibility and redox properties, as revealed by H2-TPR and XPS analysis. Therefore, the most active powder catalyst (Cu0.6Ce0.4) was then deposited on a cordierite-type monolith through a novel direct synthesis (Figure 3) and tested for the total oxidation of the VOCs. The Cu0.6Ce0.4-based monolith exhibited high activity towards the total oxidation of VOCs, which is comparable to that obtained with powdered Cu0.6Ce0.4. Since industrial emissions usually contain mixtures of VOCs, studies on the catalytic activity of a single probe molecule of VOC only partially represent the possible catalyst applications. Therefore, further investigations are currently under investigations for mixture of VOC (namely, ethylene, propylene and toluene).

A tremendous growth in wireless traffic volumes and a shortage of feasible radio spectrum has led to a situation where the old and rigid spectrum regime is not a viable option for spectrum management and a shift towards a more market driven approach has begun. Great uncertainty still exists over how such a radio spectrum market will come about and what kind of shape it would take. This paper studies some long term macro level evolution possibilities for how this radio spectrum market could emerge and what would be the corresponding value chain configurations. The scenario planning and system dynamics methods are utilized to build four alternative future spectrum market scenarios.


Cyclic addition of a hydrazine nitrogen to unactivated alkynes catalyzed by non-metals. Starting from readily accessible γ-silyl allenyl esters, β-alkynyl hydrazines are prepared in one step and subsequently undergo unprecedented cyclization reactions in the presence of ammonium and phosphonium catalysts leading to dehydro-azaproline products. These heterocycles are also produced in high enantiomeric excesses using chiral ammonium phase transfer catalysts via a kinetic resolution pathway.


A novel design of D-shaped photonic crystal fiber polarization splitter based on surface plasmon resonance is presented. The polarization splitter involves a gold nanowire and depositing of a gold film along with side-polishing of PCF. The numerical results show an ultracompact device length as short as 84 μm with extinction ratios of -21.5 dB and -41 dB and insertion losses of -0.57 dB and -0.3 dB for the x- and y-polarized modes, respectively, at wavelength of 1.55 μm.

More and more edge devices and mobile apps are leveraging deep learning (DL) capabilities. Deploying such models on devices – referred to as on-device models – rather than as remote cloud-hosted services, has gained popularity because it avoids transmitting user's data off of the device and achieves high response time. However, on-device models can be easily attacked, as they can be accessed by unpacking corresponding apps and the model is fully exposed to attackers. Recent studies show that attackers can easily generate white-box-like attacks for an on-device model or even inverse its training data. To protect on-device models from white-box attacks, we propose a novel technique called model obfuscation. Specifically, model obfuscation hides and obfuscates the key information – structure, parameters and attributes – of models by renaming, parameter encapsulation, neural structure obfuscation, shortcut injection, and extra layer injection. We have developed a prototype tool ModelObfuscator to automatically obfuscate on-device TFLite models. Our experiments show that this proposed approach can dramatically improve model security by significantly increasing the difficulty of parsing models' inner information, without increasing the latency of DL models. Our proposed on-device model obfuscation has the potential to be a fundamental technique for on-device model deployment. Our prototype tool is publicly available at https://github.com/zhoumingyi/ModelObfuscator.


Irrigation is a management option available to farmers in the subhumid zones of Sri Lanka to increase mung bean yields during the dry Yala season. The objective of this study was to quantify the yield gain in response to irrigation at different stages of the crop and thereby determine the most suitable stage/s of irrigation. Four field experiments were conducted during Yala in 1995 and 1996 at two sites, Maha-Illuppallama (MI) and Kundasale (KS). Eight irrigation regimes consisting of all possible combinations of irrigation at three growth stages of the crop were defined. The respective growth stages were vegetative (from germination to appearance of first flower), flowering (from appearance of first flower to 75 % pod initiation) and pod-filling (from 75% pod initiation to maturity). The treatments which received irrigation during two or more stages had significantly higher yields (793-1396kg ha -1 ) than those which received irrigation during only one stage (401-756kg ha -1 ) with the lowest yield being shown by the rain-fed treatment (227-396 kg ha -1 ). When at least two stages can be irrigated, irrigation during the flowering and pod-filling stages was most effective. Irrigation during flowering produced the highest yield gain when only one stage could be irrigated. Seed yield showed a strong positive correlation with number of pods m -2 . Fifity per cent depodding caused yield reductions at both sites, indicating sink limitation. In contrast, 50 % defoliation reduced the yields only at MI where the number of pods m -2 was greater than at KS. Hence, source limitation was present only when the number of pods was higher.

We report organic solar cells fabricated with small-molecule organic semiconductor tetracene/C 60 heterojunction as the photoactive layer. The external power conversion efficiency of the devices under AM 1.5 solar illumination at 100 mW/cm 2 s1 sund is 2.3±0.5% with relatively high open-circuit voltage sVoc=0.58±0.06 Vd compared to most of the other small-molecular donor-acceptor sD-Ad heterojunction solar cells reported so far. Using atomic force microscopy and x-ray diffraction we found that tetracene thin films consist of submicron-sized grains with rough surface and well defined molecular order. Therefore, using high mobility polycrystalline tetracene thin films for D-A heterojunction devices dramatically increases area of tetracene and C 60 interface for exciton diffusion to reduce the recombination. © 2005 American Institute of Physics . fDOI: 10.1063/1.1946184 g


A mathematical model of the time-dependent Martian atmosphere has been developed in order to accurately calculate the effects of aerodynamic drag on a low altitude satellite. The time-dependent properties of the model include solar activity effects, dust storm effects, seasonal and diurnal variations, and annual motion effects. Position effects are accounted for through Martian latitude and longitude. Expected values of mass density, temperature, scale height, and the estimated standard deviation of the mass density are provided. An example of the use of the model in selecting an orbit for the Mars Geochemical/Climatology Orbiter is given.


During the past 20 years from 1971 to 1991, 71 cases of esophageal foreign bodies were treated in the department of otolaryngology, Akita university hospital. These patients were clinically analyzed. The youngest patient was 10 months old and the oldest was 79 years old. Out of 71 cases, 27 cases (38.0%) were under 6 years of age. Fish bones were the most common (20 cases ; 28.2%), followed by coins (16 cases ; 22.5%). Coins were only found in children under 6 years of age. In 52 cases (73.2%), the foreign bodies were located at the first physiological constriction of the esophagus. In 10 cases (14.1%) the foreign bodies were removed by the external incision because of perforation and esophageal abscess.

The development and design of computational artifacts and their current widespread use in diverse contexts (from work/task oriented to ludic applications) needs to take into account end-users needs, likes/dislikes and broader societal issues including human values. However, the fast pace of technological developments highlight the acknowledgment that the process of defining the computational artifacts not only needs to understand the user but also engineering and designers creativity. In order to take into account these issues, we have been exploring the utilization of a framework to guide our own development efforts. The Worth-Centred Design (WCD) can be seen as a conceptual framework that intends to facilitate the process of making explicit the connections between high level concepts related to desired ends/worth/values and simple/basic/atomic features composing an (or to be) artifact [1, 2]. In this paper, our insights as a heterogeneous design team regarding the use of the WCD framework are presented. More specifically, two on-going cases studies are considered: (a) one concerning the on-going development of situated digital public displays and (b) the development of games to assist therapists of children with emotional and cognitive impairments to conduct their daily therapeutic activities. The utilization of the framework definitely improved our understanding of the relationships between features and high-level interaction goals. The representational tools and the process of constructing them helped making explicit the design alternatives and the design team assumptions regarding artifact use. However, there are hurdles to conquer, in particular, the creation of common ground within the team in relation to the definition of the terms employed and assuring that the emergence of common ground does not hide fundamental differences regarding the meaning of the design elements uncovered. Furthermore, more research is needed in order to understand how to elicit values related to the artifact from the different stakeholders of a particular social context.


Development of versatile engineering materials from locally available materials in space is an important step toward the establishment of outposts on the Moon and Mars. Here development of the technologies for manufacture of structural and construction materials on the Moon, utilizinglocal lunar soil (regolith), without the use of water, is an Important element for habitats and explorations in space. It is also vital that the mechanical behavior such as strength and tensile, flexural properties, fracture toughness, ductility and deformation characteristics are defined toward establishment of the ranges of engineering applications of the materials developed. The objectives here Include two areas: (1) thermal "liquefaction" of lunar slmulant (at about 1100°C) with different additives (fibers, powders, etc.), and (2) development and use of a new triaxial test device in which lunar slmulants are first compacted under cycles of loading, and then tested with different vacuums and initial confining or in situ stress. Details of the development of intermediate ceramic composites (ICC) and testing for their flexural and compression characteristics have been described in various reports and papers,t2 The subject of behavior of compacted simulant under vacuum has been described in previous progress reports and publications34; since the presently available device allows vacuum levels up to only 104 torr, it is recommended that a vacuum pump that can allow higher levels of vacuum is utilized for further investigation.

Stainless steelmaking produces different types of slags which need to be cooled, stored, and pretreated before further use. In current practice, the slag is cooled in an air atmosphere, but water cooling has been envisaged to speed up cooling. The aim of this article is to simulate the cooling of argon‐oxygen decarburization (AOD) slag under the conditions of ambient cooling and water cooling. The effects of the thickness and initial temperature of the slag layer are also studied. Finally, practical means to improve the cooling practice are evaluated based on the model predictions.

The invention also relates to a method for producing oxygen-depleted ceramic fibers and other molded bodies with a composition similar to that of SiC. Said method comprises the spinning of the solution to obtain green fibers according to the dry spinning method and the pyrolysis of the dried green fibers in an inert gas atmosphere or a reductive atmosphere.


The article looks at the efforts of the Interstate Commerce Commission (ICC) to fulfill often onerous and futile mandates imposed by Congress. The Hoch-Smith Resolution of 1925 that was eviscerated by the Supreme Court five years after its passage has often been seen as one of Congress's more feckless incursions into the technicalities of economic regulations. The Hoch-Smith Resolution is used to throw light to ICC's limitations as an administrative body, and on how it viewed its responsibilities in the implementation of legislatively mandated economic policy.

The experimental results show that the color features can improve the effectiveness and robustness of flame recognition system. Furthermore, it can reduce the false alarm rate in the fire recognition system.


Folate plays an essential role in cell division by participating in DNA synthesis and regenerating S-adenosylmethionine, a universal methyl donor in methylation. Folate deficiency may be involved in carcinogenesis of several type cancers through impaired synthesis and repair of DNA, or by causing global hypomethylation of DNA. So far, there is no prior report on epidemiologic data concerning the relationship between folate intake or serum folate levels and non-Hodgkin's lymphoma (NHL) risk. We performed a case-control study (432 cases and 1,700 controls) to examine the association between serum folate levels and risk of NHL. This is, to the best of our knowledge, the first study to show that serum folate levels and risk of NHL. We also investigate whether genetic polymorphisms in folate-metabolizing enzymes interact with serum folate levels in modifying NHL risk. Serum folate was measured by ion capture assay on an AxSYM Analyzer (Abbott Diagnostics, AbbottPark, IL). The geometric mean in cases was lower than in controls (e.g., 18.9 vs 22.1 nmol/L, P 22.7 nmol/L [10 ng/mL]) There was a significant thymidylate synthase (TS)-folate interaction in T-cell lymphoma subtype, but we did not observe any significant gene-folate interactions in NHL and DLBCL subtype. Among subjects with low serum folate concentration (
