The cause of Camel Xiangzi did not lie in his individual struggle thought,but lies in the paradox of existing.Xiangzi regarded the freedom and democracy that the capitalism propagandized as his liberation faith,using the experience from the countryside to meet the sense of the capitalistic city civilization.The conflict between the living fashion and the circumstance always led Xiangzi to stand in a paradox of existing.


The resistance of 240 Malus germplasm accessions to bot canker was evaluated by inoculating branches in the field with cultured mycelia from five pathogenic isolates of Botryosphaeria dothidea. Differences in the disease resistance were significant among the examined germplasm accessions and the different pathogenic isolates. In general, the resistance of the wild species and the Chinese domestic cultivars was much stronger than that of the cultivars or mutants of Malus × domestica. Baccata HR, a genotype from a wild species, is highly resistant. Three M. × domestica cultivars/mutants, Maypole, Spy227 and Fengyan, are resistant, whereas Changhong is highly susceptible. A wide range of resistance levels were observed among the 28 M. sieversii genotypes. Differences in resistance were also found among clonal mutants from cultivars of M. × domestica. The disease indices of the same germplasm in response to different pathogenic isolates of B. dothidea are sometimes significantly different.


The kinds of 5G waveforms require to saturate different demands of transmitting signals. Unfortunately, the spectrum resources are limited. Thus, the spectrum sensing technique should be overcome this issue of communications. In this paper, a spectrum sensing technique is proposed for 5G waveforms detection, such as F-OFDM, UFMC, and FBMC. The decision of detection is obtained according to some parameters such as signal length, cyclic prefix, shape, energy, and mapper. The proposed method includes windowed cosine filtering with Hamming. The results are validated with the Monte-Carlo simulation. The proposed sensing technique achieved better detection performance than that of related techniques in terms of detection probability (> 0.95), false alarm probability (< 0.05), signal-to-noise ratio (< 0 dB), and level of complexity.


The p-i-n diode is one of the earliest semiconductor devices developed for power circuit application. It is formed with the intrinsically doped i.e. i-layer sandwiched between the p-type and n-type layers. In this paper, we focus on the integration of the intrinsic region of silicon p-i-n diode to the current-voltage characteristics. In our structure, n-type refers to the bulk substrate and intrinsic region refers to the epitaxial layer of the silicon substrate. We make a thickness variation in the intrinsic region of p-i-n diode and how it affects diode performance. An additional layer is added on the epitaxial layer during the process to control the diffusion from the bottom of bulk substrate. Result shows that intrinsic layer optimization has successfully enhances the diode device robustness in terms of diode current-voltage characteristics, which reflects better manufacturing yield and improve the final product performance.


In this paper, a general analytical model is proposed to investigate various eccentricities in double rotor axial flux permanent magnet (DRAFPM) machine, the back electromotive forces (EMFs) is calculated and compared in this paper. At first, the radial and tangential flux density in the air gap under healthy condition is developed via Maxwell's equations and Schwarz-Christoffel mapping. After that, variable air gap length and radii are introduced to calculate the flux density caused by eccentricities. The back EMF at each case is calculated and compared with that in healthy condition. At each section, FEM models are built to validate the analytical model, and the results show that the analytical model predictions agree well with those from the FE results. Finally, the analytical model is verified via experimental results.


Effective appropriation of new technology has long been considered essential for innovation. Yet, the role of patents and other Intellectual Property tools has been questioned, both for rewarding innovators and serving societal needs. Simultaneously, there is ample empirical evidence of technological advance accelerating under conditions of loose appropriability, for example, when patents expire and cases of innovations based on shared technology and diverse motivations. This paper explores the case of the 3D printing technology, which appears to have found successful commercialization and dynamic market growth after key patents expired. We analyze the role of commons-based peer production practices in forging synergies among different factors and effectuating an alternative innovation pathway and the challenges and contradictions in the process. Finally, we critically assess recent developments of 3D printing technology and draw lessons for innovation policy by incorporating aspects of emerging commons-based innovation paradigms.


Fifty pairs of mothers and their 15 to 18-year-old daughters participated in a study that investigated the role of the mother-daughter relationship in the process of psychological separation in adolescence. Psychological separation was expected to be predicted by maternal empathy and by the conceptual complexity of the self and object representations of the mothers and daughters. Psychological separation of the daughter was measured by the Psychological Separation Inventory (PSI) and a combination of two PSI subscales. The mother's capacity for empathic understanding of her daughter was determined by a congruence score derived from the Offer Parent-Adolescent Questionnaire and the Offer Self-Image Questionnaire. Mothers and daughters wrote brief descriptions of themselves and each other, which were scored for conceptual complexity. Although the total PSI score was not predicted by the Congruence score and the complexity of the representations, when combined Conflictual and Emotional Independence subscales...


In Mexico, the prevalence of exclusive breastfeeding in children under 6 months of age has decreased significantly from 22.3% in 1999 to 14.5% in 2012. The deterioration of breastfeeding practices has affected vulnerable groups of women: a) rural women in the southern region of the country, b) those in the lowest tertile of socioeconomic status, c) those with education lower than primary, d) those without access to health services or without paid employment. Currently, Mexico does not have a National Breastfeeding Program.


The paper has been intended to introduce a method of evaluating time of fatigue crack growth to limiting value for some selected structural components during aircraft's operation process. The method, base on stress intensity factor and Paris' formula, which describe physical nature of the process. To describe the dynamics of the crack propagation was used a partial differential equation of the Fokker-Planck type. Having solved this equation enables the density function of the crack length to be found. This function, gave possibility of determination time density function when fatigue crack growth achieves limiting value.


It is commonly assumed that the cost of living is much higher in cities than in the country because housing rents are higher in urban areas and food staples cost more. This assumption has important implications for sectoral comparisons of welfare levels and distributions. The authors suspect that comparisons of housing rent and food prices overstate the cost-of-living differential. For one thing, the quality of dwelling stock is better on the whole in urban areas, reflecting income differences. For another, the urban consumer is able to substitute in favor of other goods and services which do not cost any more in urban areas. This paper finds that the true cost of living in cities is substantially overestimated by conventional methods. This is more pronounced at low incomes, since the marginal cost of utility is larger (relative to expenditures) in urban areas - implying that the relative cost of urban living increases with income. In a neighborhood on the poverty line, the results suggest that an urban-rural cost-of-living difference of about 10 percent is closer to the truth than the values (as high as 66 percent) used in past work on Indonesia.


Efficient web browsing demands effective aid in searching anticipated content. Recommender systems are prodigious source of providing assistance to the internet users. Diverse algorithms are in practice to give recommendations. All recommender systems work on policy of scrutinizing behaviors of users. They find neighbors of each user to give final recommendations. Similarity Matrix computations outcomes in developing the recommendations for each user. However, accuracy of recommendations depends upon the correctly made predictions. Hence, web page recommendation system demands improvements in the traditional practices. This paper verdict the differences in results for user based collaborative filtering recommendation strategies and clustering users before implementing recommendation algorithm for web page recommendation system. Results are compared through computation of RMSE. Differences in results suggest that accuracy of recommendations is improved if clustering-based approach is applied for recommendation of web pages. This study gauges the results on the web log data set to recommend users the required content on the internet by evaluating the browsing behavior with PCC similarity measure.


When James Joyce's Ulysses was first published in America, it quickly became a dynamic symbol of both modern art and the modern age. Jeffrey Segall skillfully demonstrates how various political, ideological, and religious allegiances influenced the critical reception and eventual canonization of what is perhaps the twentieth century's greatest novel. In re-creating the polemical debates that erupted, Segall provides a dramatic reminder of just how challenging and controversial Ulysses was--and is. Seventy years after Ulysses was first banned, the novel remains at the center of contemporary debates among feminist, neo-Marxist, and poststructuralist critics. Segall allows us the opportunity to view Ulysses from the perspective of its early readers, and he also elucidates key moments in recent American cultural history.


Research indicates that mothers scaffold the literacy skills of their children when jointly engaged in literacy-related activities in monolingual families (Tamis-LeMonda et al., 2001). Yet little is known about the linguistic environment of English language learners in the USA, a group at high risk for reading difficulties if they are only taught in English and the school is not mindful of their linguistic and cultural strengths (Snow et al., 1998). We studied mother–child language interactions in Spanish-speaking families in the USA during two literacy-related activities at home (book reading and a homework-like task). We employed language data analysis, discourse analysis, surveys and observations to study four cases of mother–child communication and its relation to the children's literacy and language skills (letter-word identification, dictation, vocabulary). Mother–child proficiency in the same language (Spanish, English or bilingual similarities between mother and child) was necessary, but not sufficient, to facilitate their communication. Maternal language and literacy skills in this sample related to the quality of language input, but only in dyads with shared language did it relate to successful communication and the child's skills. Continuity between home/school language and literacy showed compounded support for language that transferred to literacy skills across languages. This association was observed even in dyads with mothers who had scored low on receptive vocabulary or/and had only a few years of formal education. These findings suggest that maintaining a school language environment that preserves mother–child communication and its positive association with learning would yield the best educational outcomes for this particular population.

By heating under water vapor, ferrite was formed from coprecipitate made from constituent sulfate solution or wet mixture of component hydroxides, similar to the case of hydrothermal synthesis. Temperature (100°C-300°C) had a marked effect on the velocity of the formation.In the case of Ni ferrite, pressure of water vapor played an important role on the formation, while in the case of Zn ferrite, it appears that only a small amount of water vapor was enough for the formation.Even from the dry mixture of component hydroxides, ferrite of normal structure was formed. The formation by this process from the coprecipitate or wet mixture heated in air up to 250°C was also evident.From these results, some discussions were made on the mechanism of the formation.


Glioma is a malignant tumor with high mortality. Cell invasion and metastasis are important lethal factors of it, which can be caused by matrix metalloproteinases (MMPs) dissolving the extracellular matrix. MMPs are zinc- dependent proteolytic enzymes and widely distributed in various tissues and organs. MMPs participate in the degradation and rebuilding of extracellular matrix, regulating cell adhesion, playing an important role in the tumor invasion and metastasis. In this review, we put emphasis on the role of MMP-2 and MMP-9 in glioma invasion and the mechanism. Keywords matrix metalloproteinase-2; matrix metalloproteinase-9; glioma; invasion and metastasis

The editorial is concluded through a short presentation of the articles in this special issue.


One way to proxy the outcome of the R&D process is to count the number of patents a firm has generated. However, there are several problems with the use of the number of patents as an indicator of R&D-output (Griliches, 1990). However, the correlation between changes in R&D spending and generated patents is quite high (Pakes and Griliches, 1984). Different uses of patents as indicators of technological progress range from 'simple' patent counts (Johnson et al., 1995) to the use of 'specific' input-output techniques to measure the interaction between sectors in the innovative process. The purpose of this paper is to examine whether the techniques that are applied to inputoutput tables can also be used for the typical analysis of the specific data on patents and innovations. The data used in this study denote make and use of patents or innovations by sector. By applying the techniques developed, it is possible to pinpoint the sectors that are the most important for innovative activities and the sectors that generate the highest number of patents due to interaction with other sectors. Since these specific data are scarce only Canada is investigated empirically. ∗Faculty of Economics, University of Groningen, P.O. Box 800, 9700 AV Groningen, The Netherlands.

Vegetation monitoring is pivotal to improve our understanding of the role vegetation dynamics play in the global carbon-, energyand hydrological cycle. And with the increasing stress on food supply due to the growing world populating and changing climate, vegetation monitoring is of great importance in agricultural areas. By closely tracking crop conditions, droughts and subsequent crop losses could be mitigated. Sensors operating in the microwave domain are sensitive to several surface characteristics, including soil moisture and vegetation. Hence, spaceborne microwave remote sensing provides the means to monitor vegetation and soil conditions on different scales, ranging from field scale to global scale. However, it also presents a challenge since multiple combinations of soil and vegetation characteristics can lead to a similar measurement. Copernicus Sentinel-1 (S-1) is a series of two satellites, developed by the European Space Agency (ESA) , which carry C-band Synthetic Aperture Radars. The C-SAR sensors provide VV, HH, VH and HV backscatter at a 5 m by 20 m spatial resolution. The temporal revisit time of the two satellites is 3-6 days. With their unique capacity for temporally dense and spatially detailed data, the S-1 satellite series provides for the first time the chance to investigate vegetation dynamics at high temporal and spatial resolution.

Abstract : A Simulation Game to train data processors in optimal data recovery techniques is included in this report. Also, the authors studied the triple- multiplexing response to a point source for a future scanning spectrometer. Three basic motions are required to modulate the wavelength and angular coordinates of the source. When performing preliminary experiments with the Multiplex Scanner, the authors discovered that the underlying Talbot effect is useful also for measuring phase objects. The theory of this new Talbot Interferometer is explored and experimental results of a candle flame are reported. For axially symmetric objects, this setup is modified by replacing the straight line gratings with circular gratings. In this way the radial gradient of the deformed wavefront is observed. Finally a means of simply, yet accurately collimating a light source using the Talbot Interferometer is described.


43 THE SENATE COMMERCE COMMITTEE met May 3, 2001 for the mark-up of S. 718, which would modify the Professional and Amateur Sports Protection Act (PASPA) to ban legal college sports wagering in Nevada. An amendment to the bill offered by Sen. John Ensign (RNev.) which would have essentially killed the legislation, failed to pass in a tie vote, 10-10. Amendments to S. 718 approved by the Senate Commerce Committee include those requiring colleges and universities to report statistics about gambling-related offenses; requiring colleges and universities to monitor students' and employees' Internet traffic and filter Internet gambling sites; exempting office pools from the betting ban; making credit card debts owed to offshore Internet gambling sites uncollectible; and providing an expedited judicial review in the event that this bill becomes law. The amendments that were not approved include those providing due process for college student-athletes and establishing 21 as the legal gambling age nationwide. The Senate Commerce Committee held a hearing April 26, 2001 on S. 718. Expert witnesses who testified against the bill included Hall of Fame basketball coach Pete Newell; Howard Shaffer, director of the Division on Addictions at Harvard Medical School; and Danny Sheridan, a sports analyst from USA Today. S. 718 was introduced by Sens. John McCain (R-Ariz.) and Sam Brownback (R-Kan.) on April 5, 2001. A similar bill, H.R. 1110, was introduced March 20, 2001, by Reps. Lindsey Graham (R-S.C.) and Tim Roemer (D-Ind.) and has been referred to the House Judiciary Committee. Both S. 718 and H.R. 1110 would prohibit college sports wagering in Nevada, the only state where it is legal. On Feb. 14, 2001, S. 338 and a House companion, H.R. 641, were introduced as part of an effort to address the real problem of illegal gambling. H.R. 641 was introduced by Reps. Jim Gibbons (R-Nev.) and Shelley Berkley (D-Nev.), and has acquired 88 bipartisan cosponsors. It was referred to the House Judiciary Committee and the Committee on Education and the Workforce. S. 338, introduced by Sens. Ensign and Harry Reid (DNev.), also has gained strong bipartisan support with cosponsors such as Sens. Orrin Hatch (R-Utah) and Max Baucus (D-Mont.). This bill has been referred to the Senate Judiciary Committee.


The invention relates to a method for evaluating completeness of a concrete pile body by virtue of wave train figure event image characteristics on the basis of an elastic wave transmission method. The method comprises the following steps: (1) preparing and testing in situ; (2) processing data; and (3) evaluating the completeness of the pile body, wherein a longitudinal wave which spreads along the pile body and a stoneley wave (tube wave) which spreads along a tube wall can be seen from the characteristics of an event image of a wave train figure and can be transmitted and reflected when encountering a wave impedance interface, and as different wave train figure event image characteristics can be formed according to piles with different pile body completeness, the piles can be classified into complete piles, defect piles and broken piles according to the characteristics so as to evaluate the pile body completeness of a to-be-detected pile. The method has the advantages of intuitiveness, accuracy, reliability and the like. By the method, the reliability of the detection result and the analysis speed of detection data can be guaranteed, the construction progress and safety can be further guaranteed, and the social benefit and the economic benefit are remarkable.

The feasibility of using ultrasonic testing, in particular P-wave velocities, to evaluate stabilized soils was investigated. A high-plasticity clay soil that was stabilized with lime, cement, and lime — fly ash mixtures was used in the study. The testing program consisted of determination of P-wave velocities and compression characteristics of the stabilized soils immediately after compaction and subsequent to 7 days and 28 days of curing. Variation of velocity with stabilizing agent, curing time, and also with the compression characteristics of the soils was investigated. It was observed that P-wave velocities were higher for samples stabilized with cement compared with samples stabilized with lime and fly ash. In addition, velocities increased with curing time for all the stabilized mixes. In general, the velocities of the samples increased as the unconfined compressive strength of the samples increased. However, there was a substantial amount of scatter in the data. The trends observed in the modulus data were better and the P-wave velocities of the stabilized soils increased as the modulus of the soils increased. Also the variation of modulus with time was similar to the variation of velocity with time. In addition, the P-wave velocities increased as the densities of the samples increased.


In this paper,the application of the sand cone model in supply chains was discussed and new research avenues were opened in the research of the compositeness of supply chain.The strategic competitive advantage of supply chain can be achieved by improving competitive priorities in a specified sequence: quality,reliability,flexibility,agility,and cost efficiency.This study provides a theoretical framework for supply chain,which a cumulative and sustainable competitive advantage could be established.


Nutritional indices and biochemical profile of Helicoverpa armigera in response to feeding on different groundnut genotypes was studied. The moderately resistant genotypes were ICGV 86699, ICGV 86031, ICG 2271 and ICG 1697. JL 24 was used as the susceptible check. Consumption index (CI), approximate digestibility (AD), efficiency of conversion of ingested food (ECI) and efficiency of conversion of digested food (ECD) were recorded. In addition, the activities of digestive and defensive enzymes of H. armigera were studied. H. armigera larvae showed significantly lower CI, AD, ECI and EDI when fed on moderately resistant genotypes than the insects fed on JL 24. Serine protease and trypsin activities were low in insects fed on resistant genotypes than the ones fed on JL 24. Further, insects fed on resistant genotypes showed significantly greater glutathione-S-transferase activity than the insects fed on JL 24. A reverse trend was observed for esterase activity. Similar trend was observed for total protein content of the insects. Thus, nutritional quality of host plants affects insect's physiology and could be used as an important indicator of host plant resistance against insect pests and to understand the adaptation of insect pests, if any, to various genotypes/host


demonology. The conclusion of this rather elaborate monograph does not amount to a great deal more than what I wrote as a summary of common knowledge on the subject twenty years ago. Of Platonists like Plutarch I said "Their solution of how to reconcile polytheistic practice with philosophical monotheism was to identify the gods of popular polytheism with daemons. But further than this, it was admitted that daemons, all of whom, though incorporeal, shared the imperfections necessarily resulting from contact with the world of mutability, were both good and bad. Here was a rival explanation to Stoic allegory for the crudities of mythology, for historical instances where an oracular god had been proved to lie, and also for savage or revolting forms of primitive ritual.' I confess that a good part of the book, while impeccable research by the approved methods, seemed a little like a laborious proof of what everybody knows, and I personally found more interesting the discussion of their eschatological and psychological ideas in the myths of the de fac. in orb. lun. and the de ser. num. vin., which form the concluding chapters of the treatise. Here and there one could, of course, find details with which to disagree. For example, as indicated in my note to Plutarch, Q.G. 12, I should not agree that the burning of the hut at Septerion was correctly to be explained as the burning of the Delphic dragon's lair. In the closing chapters, again, the author seems dangerously inclined to connect any idea for which he can find Orphic authority with the mysteries, in my view a non sequitur. But by and large the monograph is undoubtedly a piece of careful work by an accurate scholar of wide knowledge and good sense.


Blood changes were followed for several days after irradiation of adult rats with 190-kv x rays at a rate of 42 r/ min to a total dose of 1200 r. No changes in blood coagulation were noted the 1st two days postirradiation, but beginning on the 3rd day a prolongation of clotting time was noted. This was accompanied by a fall in the level of circulating free heparin, increase in prothrombin, factor V, and factor VII. Thrombin time and thrombin time determined with toluidine blue were decreased; the latter measures heparin-like antithrombin activity. The increase in prothrombin reached 150% after 72 hr and 210% after 80 hr. Elevations of factor V and factor VH were 170 and 140%, respectively. These findings are discussed in terms of the release of kinases and activators of other types from injured irradiated tissue into the circulation which may also be promoted by the resulting tissue anoxia.

The visual system of sighted animals plays a critical role in providing information about the environment, including motion details necessary for survival. Over the past few years, numerous studies have explored the mechanism of motion direction detection in the visual system for binary images, including the Hassenstein–Reichardt model (HRC model) and the HRC-based artificial visual system (AVS). In this paper, we introduced a contrast-response system based on previous research on amacrine cells in the visual system of Drosophila and other species. We combined this system with the HRC-based AVS to construct a motion-direction-detection system for gray-scale images. Our experiments verified the effectiveness of our model in detecting the motion direction in gray-scale images, achieving at least 99% accuracy in all experiments and a remarkable 100% accuracy in several circumstances. Furthermore, we developed two convolutional neural networks (CNNs) for comparison to demonstrate the practicality of our model.

Sufficient fetal fraction (FF) is crucial for quality control of NIPT (Non‐Invasive Prenatal Test) results. Different factors influencing bioinformatic estimation of FF should be considered when implementing NIPT. To what extent the total number of sequencing reads influences FF estimate has been unexplored. In this study, to test the robustness of SeqFF FF estimation and provide additional recommendations for NIPT analysis quality control, we compared the SeqFF FF estimates with two other methods and investigated how the number of sequencing reads and FF level affects the accuracy and precision of FF estimates.


BACKGROUND
The magnitude of various types of subcutaneous mycoses in Ethiopia is unknown.

METHODS
We performed a 5-y retrospective review of confirmed cases at ALERT hospital dermatology clinics.

RESULT
Confirmed cases of subcutaneous mycoses included chromoblastomycosis (n=12) and mycetoma (n=8). The patients originated from four regions: Oromia (n=10), Amhara (n=6), Addis Ababa (n=3) and South (n=1). Males were affected in 75% of cases (15/20). Ages ranged from 19 to 66 y with a median age of 44 y. Duration of disease ranged from 1 to 25 y. Extremities were affected in all cases, with lower limb involvement in 85% (17/20).

CONCLUSION
Chromoblastomycosis was the most frequent subcutaneous mycosis followed by mycetoma.


The aim of the study was to characterize the Bacillus subtilis ATCC 6051a strain, in order to establish its probiotic utility in piglet nutrition. The strain was assayed morphologically, culturally, biochemically, for hemolytic activity and enzymatically (amylase and protease). The identification and analysis of the biochemical characteristics was performed by catalase assay, API 50 CHB Biomerieux strips, apiweb API 50 CHB V 4.0 soft (B. subtilis very good identification, 99.4% ID) and ABIS online. The hemolytic activity was assayed on blood agar medium. The growth activity of strain was evaluated in two ways: static incubation (30 C, 24 h, 1.36 x 10 CFU/ml) and under constant agitation (30 C, 24 h, 150 rpm, (1.6 x 10 CFU/ml). The strain is a Gram positive and rodshaped bacteria, arranged in short chains or in small irregular pairs with ability to produce spores on nutrient medium. The endospores were central, paracentral and subterminal, which did not deform the vegetative cell. The strain growth was aerobic and was non – hemolytic. The enzymatic process was observed by appearance of distinct zones around strain colonies. In conclusion, the results suggested that the strain present probiotic traits and can be further assessed for other probiotic characters (resistance to pH 2.0, resistance to bile acids and salts, antibacterial activity, induction of local immune response etc.).


Spontaneous quantum phase slips by 2π in thin superconducting wires could cause errors in superconducting computers. The rate of such phase slips at T≪Tc is estimated, and shown to be very small as long as the wire is >20 nm in diameter.


The central question-problem that this article presents has to do with the critical analysis that the authors of Critical Theory, particularly Adorno and Horkheimer, established between the project of enlightenment and the limits of emancipation of the individual. From this theoretical approach it is intended to show if it is possible to think in an emancipatory project in the context of today's capitalist society. On the one hand, it is sought to question the contradiction: the enlightenment as a promise of a better society and what of it, indeed, became: a totalitarian reason. On the other hand, it is intended to understand if, from the positioning of the authors, before the alleged project of enlightenment, philosophy and education would have a power of resistance related to the chaotic path that the civilizing process has taken.


The Turkish language has borrowed a significant number of words from Western languages and, in particular, 4974 words have been borrowed from French (Saglam, 2007). Therefore, the Turkish lexicon includes a number of words that share a similar meaning, spelling, and/or pronunciation with related French words. These words, on the border of both languages are referred to as "cognates".
Previous studies on cognate word processing in bilingual speakers during L1 and L2 produc-tions have found a robust cognate facilitation effect in picture naming (Yan, 2014). Research-ers (Costa et al., 1999; Kroll et al., 2008) have also identified that if the cognates do not share phonology or meaning (i.e., false cognate inhibition effect), this effect may become inhibitory. These mixed findings seem to suggest that semantics, phonology and orthography may con-tribute differently to cognate word processing.
This presentation aims to characterize the development of the lexicon of Turkish-French bi-lingual children with the purpose of better determining the nature of the difficulties they en-counter as well as the specificities of their functioning. In order to do this, 16 French-Turkish bilingual, 16 French and 20 Turkish monolingual 5 year-old nursery school children were asked to name pictures whose names (i) are cognates and (ii) non cognates in both lan-guages. We established a list of 74 items, including 35 cognate and 39 non-cognate items.
Our results reveal high performances for the cognate word recognition task for French-Turkish bilinguals. This proves that these bilinguals implicitly knew these common words. On the one hand, this result questions the idea that a bilingual would not use words resulting from his L1 when he produces the word in his L2 and, on the other hand, supports arguments in favor of the theory according to which both languages are activated for bilinguals even when using only one language


The effectiveness of yellow sticky traps(YST) in different height and time in inspection of population dynamics of sweetpotato whitefly,Bemisia tabaci(Gennadius) and its parasitoids were studied in this work.Results showed that the largest trapping amount of B.tabaci and its parasitoids on YST was obtained when kept the top of YST in the same height as the top of tomato plants,the lesser amount was trapped when kept the top of YST in the middle of plants,and the least amount was obtained when kept YST 30 cm higher than the top of plants.The trapping amounts of B.tabaci and aphelinids on YST increased continuously during May to October. The species of aphelinids trapped by YST belonged to two genera,Eretmocerus Haldeman and Encarsia Ferster.The populations of these two aphelinids were seasonally complementary,so the total parasitism of B.tabaci kept increasing on tomato during May to October.


To investigate the influence of two kinds of aphrodisiac way to the estrus and ovulation of unpregnant sows,three hundred long-term unpregnant sows were randomly divided into three groups.Group 1 was treated as control,the other two groups were sports lighting and boar test.The results showed that the aphrodisiac effect of light exercise increased significantly,but also improved the alive rate and increasing the productivity of sows.

And then, this paper advances an improved scheduling algorithm for HRT traffic stream which sets up the messages HRT attribute and adjust the transmission opportunity dynamically, aiming to guarantee HRT messages QoS. Finally, the improved algorithm is implemented based on NS2 and the simulation result shows the optimized algorithm can improve the HRT traffic QoS effectively.


Polyurethane recycling is a topic of growing interest due to the increasing amount of polyurethanewaste. The main purpose of polyurethane feedstock recycling is to recover the starting polyol, a valuable material. In thiswork, amethod of polyurethane thermo-chemical recycling, glycerolysisbymeansof crude glycerine, is proposed. Themaineffort is focusedonthe employment of crude glycerine without purification from biodiesel production as a decomposing agent for polyurethane recycling. The influenceofpolyurethane-to-glycerinemass ratio (PU/GL)onchemical structurewas examined using Fourier transforminfrared (FTIR) and 1H NMR spectroscopies and gel permeation chromatography (GPC). Glass transition temperature (Tg) and thermal properties using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and also rheology were analysed. FTIR and 1HNMRanalyses of the glycerolysates showed peaks similar to those of virgin polyol. FromGPC chromatogramsitwas concluded thatglycerolysates are amixture of compoundswith different molecularweights, such as recoveredpolyol, urethane oligomers or carbamates. Glycerolysates indicated Tg in the range from −65 to −60 ∘C and, for high PU/GL ratio, a second Tg appeared. Thermal stability of glycerolysates increased with increasing PU/GL ratio. The molecular weight of glycerolysates ranged from 700 to 1020gmol−1 depending on PU/GL mass ratio. The semi-products were defined as non-Newtonian fluids, where viscosity depended on the shear rate. Crude glycerine, derived from biodiesel production, was successfully used in polyurethane decomposition, resulting in valuable semi-products.

Introduction HR-HPV infection is one of the most often diagnosed viral STIs and has been linked to some anogenital malignances. HPV vaccines have not yet widely been approved for men, representing an important source of HPV transmission between sex partners. The earliest detection plays a crucial role in decreasing of a number of HR-HPV-infected (wo)men and some screening programs may be helpful. In Russia reliable figures regarding HR-HPV prevalence remain highly limited. This primarily results from the lack of any internationally valuable screening program on HR-HPV infections among both general population and high-risk groups. This information is important for not only epidemiological purposes and transmission studies but also has a great clinical impact. We investigated the concordance of HR-HPV infection detected in different lab settings across St. Petersburg as compared to the results obtained in Amsterdam to start the first screening program. Material and Methods In parallel penile (G) and urethral (U) swabs, and expressed prostate secret (EPS) were collected in 134 enrolled in the study on heterosexual men with no STIs tested. The presence of HR-HPV DNA in the penile, urethral swabs and EPS samples was investigated in five commercial clinics/labs in St. Petersburg by two most common in the country diagnostic kits (local manufactures) and in Amsterdam (VU University) by the validated worldwide used GP5+/6+ assay, respectively. Results The results are presented in the Abstract P3-S4.01 table 1. HPV prevalence in the study group was relatively high: up to 30% (RT-PCR). In house RT-PCR assays used in St. Petersburg five labs showed low similarity and detected less HR-HPV types in urogenital samples as compared to the setting in Amsterdam (p<0.0001).

(3) Suboptimal HR-HPV diagnostics observed between techniques used in the study settings St. Petersburg as compared to GP5+GP6+. There is an urgent call for the internationally valuable HPV screening and detection programs in Russia. At the moment we additionally: (1) extent the study group, (2) include females and (3) investigate the concordance between HPV typing in the labs.


Abstract The oxidation of bagasse pith, a lignocellulose material, with potassium permanganate in dilute sulfuric acid solution creates active sites for grafting onto lignin and holocellulose. The grafted poly(methyl methacrylate) chains on lignin and holocellulose were separated, respectively, by delignification with sodium chlorite and hydrolysis of holocellulose with 72% sulfuric acid, and their molecular weights were measured. Lignin shows quite higher reactivity to grafting than does holocellulose. The roles of phenolic hydroxyl, alcoholic hydroxyl, and carbonyl groups of lignin are discussed by investigating the effect of pretreatments of lignocellulose on grafting, and a suitable grafting mechanism is proposed.


Integrins are heterodimeric cell surface protein composed of alpha and beta subunits that mediate cell-cell,cellextracellular matrix,and cell-pathogen interactions.This paper reviews current knowledge about the role of integrins in bacterial pathogenesis and some potential methods to prevent or cure bacterial infections.


Justicia gendarussa Burm. f. leaves was found to be traditionally used as male contraceptive agent by several ethnic groups in central part of Papua, Indonesia. Previous study showed that J. gendarussa could inhibit mice spermatozoa penetration onto mice ovum. It was found that J. gendarussa could be developed as contraceptive medicine. Hence, it is necessary to conduct research on its toxicity. One of the premedical researches which have carried on this research was subacute toxicity test.The aim of this research was to observe the influence of water fraction of J. gendarussa leaves on rabbit's liver and kidney functions. The parameters used on this research were SGOT, SGPT, Alkaline phosphatase, Blood Urea Level, and creatinine level. Research was carried out by administrating the treatment groups with oral preparation of of J. gendarussa leaves water fraction once daily for 45 days (1,5 times of rabbit spermatogenesis cycle). The doses of J. gendarussa water fraction for each treatment groups were 579,48; 482,90 and 340,87 mg/kg BW. Rabbit serum samples were collected and measured by Automatic Hitachi Analyzer 902. Data then were analyzed by paired t test. Result showed that J. gendarussa leaves in the three doses did not influence rabbit's liver and kidney functions.


I T HAS BEEN MORE THAN A DECADE SINCE CALIFORNIA voters passed a ballot initiative entitled "Proposition 187." Though it was later declared unconstitutional, the measure would have denied unauthorized immigrants access to all public benefits. Slightly less than two years later, passage of the federal-level welfare and illegal immigration acts in 1996 effectively barred not only unauthorized immigrants, but also almost all non-citizens from receiving food stamps and supplemental social security. States, meanwhile, were permitted to exclude most noncitizens from three other important federal anti-poverty programs. Taken collectively the three policy initiatives reflect a lingering ambiguity felt by many U.S. residents concerning the impact of unauthorized immigration. Although it may be true that some unauthorized immigrants are motivated to migrate to the United States to tap into publicly available resources, it is generally recognized that most enter to build a better life for themselves and their families by securing a higher paying job. Targeting immigrants' behavior in the form of labor market competition in the United States certainly is not new. But the legislative developments during the 1990s represented the first time in U.S. history that immigrant use of welfare caused a major immigration policy change. But perhaps more striking is the almost complete lack of credible, systematic research on the economic impact of unauthorized immigrants. Amid this dearth of credible studies, restrictionist immigration policy galloped apace. Consider the claim that unauthorized immigrants take jobs away from, or depress the wages of, lower-skilled, U.S-born, minority workers. Before 1994, only two quantitative studies employing random data had been published on this subject. The first was undertaken in the late 1980s by a team of University of Texas researchers using 1980 U.S. Census data. They reported that although legal immigrants had a small negative effect on the wages of U.S-born white workers in the U.S. Southwest, undocumented Mexican immigrants actually had a small positive effect. University of Toledo researchers in the early 1 990s used the same data. This time, however, they investigated the impact of undocumented immigrants on the unemployment of U.S-born youth and minority workers, and found TRACKING THE ECONOMY


Community engagement professionals experience numerous barriers even though community engagement is the third mission of the university alongside first, teaching and learning, and second, research. Community engagement professionals often refer to community engagement as the "stepchild" of higher education. Yet there are also inter-related successful drivers. This article identifies the barrier–driver duality and makes a case for their systemic interconnectedness, an area that has thus far been underexplored. A prominent barrier for community engagement professionals is that there is a lack of substantive conceptualisation of community engagement, intensified by the contradictory placing of community engagement within community and university structures. Interconnected to such barriers, prominent drivers demonstrate the value of scholarly, reflective practice and to enhance the leadership role of the South African Higher Education Community Engagement Forum, inclusive of the views of pertinent members such as academic leaders, students and communities.

The invention belongs to a precision design of a mechanical mechanism, specifically to a worktable fine-tuning and locking mechanism for a suspended lifting platform. The worktable fine-tuning and locking mechanism for a suspended lifting platform comprises a scale and a frictional disc fixed on a worktable and a fine-tuning and locking base; fine-tuning screws are arranged at both sides of the fine-tuning and locking base and a fan-shaped block is arranged inside the fine-tuning and locking base. Partial arc of the frictional disc is located in the fan-shaped block. A locking nut is arranged in the lower layer of the fine-tuning and locking base. The worktable can position the directional angle and can be fine-tuned and locked through design of structures such as the fine-tuning and locking base, the fan-shaped block, the circular copper block and the locking handle and the like. The whole device has a compact structure and high angular resolution (maximum 0.25 degree). The locking force designed for the locking structure consisting of the frictional disc, the fan-shaped block and the circular copper block and the like is huge and locks the frictional disc completely so as to lock the worktable. Meanwhile, the fine-tuning operating process is simple and the tested product can be tested at different directional angles so that the invention is reliable to lock and has good test and use effects.


Online surveys present a quick and efficient method to collect user experience data. However, they are less effective at extracting qualitative data. Due to response fatigue when answering open-ended questions, the quality of responses may be poor, and participants can skip answering individual questions, or drop out from the survey entirely, potentially introducing bias. To address these challenges, we developed a prototype tool that enables a test moderator to initiate a chat intervention with a participant at any point during the completion of an online survey. Through this approach, participants can be prompted to return to complete unanswered questions or provide clarification to given answers. A functional prototype system has been implemented and, as future work, will be evaluated with a variety of content and question types.


Item: Your most productive commercial Loan officer tells you that he has waived the flood insurance requirement on an industrial property located in a flood hazard zone because the borrower didn't want to purchase flood insurance and he is a "good customer." Item: Your customer objects to purchasing flood insurance on her office condominium unit because it is on the opposite end of the part of the building that is in the flood hazard zone. She is only there during working hours anyway, she argues, so her unit therefore shouldn't have to have flood insurance. Item: The head of Loan Operations just sent you a memo explaining that, due to a programming shortcut, the system has failed to track flood insurance on loans subject to the insurance requirement. Already, his people have identified seven loans on which the insurance has lapsed. He wants to know what he should do--if anything. Item: Several weeks after a hurricane blew through, your borrower calls to announce that he will no longer be making payments on the mortgage because the house on the property has washed away. You advise the customer that--house or no house--he is still obliged to repay the loan. Three days later you receive a call from your borrower's attorney, who notifies you of the borrower's intent to sue the bank for failing to take steps to require the borrower to maintain flood insurance. They will be seeking damages. Can these situations happen to you? Is flood hazard insurance really important? The answer is a resounding "yes!" Flood hazard insurance is at the top of your examiner s list. You should also know that there is zero tolerance for violations. Any exam or audit findings that indicate a pattern or practice of violations will result in civil money penalties. Why do customers and lenders resist flood insurance? It may seem like an unnecessary extra and a good way to keep costs down. But statistically, a building is more likely to be damaged by flood than by fire. Flood insurance requirements have a bottom line: No insurance, no loan. This is not something that can be "waived," nor are insurance requirements affected by the customer's value to the bank. Do any of your loan officers or customers object to fire hazard insurance? Compliance meets safety and soundness As examiners find violations, the penalties are beginning to roll in. This is money you can avoid spending simply by having an effective compliance program. The most important reason to have insurance is the safety and soundness of the loans you make. Property located in a flood hazard zone, by definition, is more likely than other properties to be damaged by a flood. Loans secured by property located in a flood zone are not safe and sound unless supported by flood insurance. Insurance guarantees the lender a return even if damage to the security property occurs. Seen in this context, flood insurance is largely a matter of accepting the idea and the need for it. Unfortunately, it will take more than acceptance to bring compliance violations under control. Any compliance veteran can testify that detailed rules seem to generate violations. It isn't so much that the bank has to do something, but more that the bank has to do it at a specific time and in a specific way. And the rule exists because the activity being regulated wasn't happening voluntarily. As with any compliance regulations, flood hazard compliance must be built into lending procedures. Without them, management cannot be certain that compliance actually takes place. understanding the process Let's take a look at what flood insurance compliance involves. What. Flood insurance requirements are triggered whenever a loan will be secured by "improved real property." The simplest definition for this is anything that can wash away in a flood. …


Knowledge distillation enhances the performance of the student model by transferring knowledge from the teacher model. Moreover, the attention mechanism has been introduced recently to enable each layer of the student to learn knowledge from all teacher layers, which brings about considerable optimization. However, noted that features from different layers, such as shallow and deep layers, might have a big semantic gap, and compulsively aligning one student layer to all teacher layers would mislead the learning process. To tackle this problem, an effective framework called Semantic Stage-Wise learning for Knowledge Distillation (SSWKD) is presented in this paper. We divide all layers into shallow and deep stages, and only allow feature alignment within the same stage to alleviate semantic mismatch. In addition, with the observation that the performance of deep networks relies more on some key features rather than evenly on all of them, a crucial feature enhancement method based on KL divergence is then proposed for SSWKD, forcing the student to pay more attention to critical features of the teacher. Extensive experiments and visualizations show that our SSWKD outperforms other distillation methods on CIFAR-100 and COCO2017 datasets for image classification, object detection, and instance segmentation tasks.


It is a common but not unrealistic stereotype of Asian students that educational success is a matter of personal identity and status. As such, achieving distinctions in as many subjects as possible (the popular target of becoming a 'straight A' student) is usually a non-negotiable objective nurtured by both parents and educators. Such an obsessive pursuit of academic excellence produces both laudable outcomes (e.g. the tendency of Asian students to outperform their counterparts) as well as dangerous ones (e.g. worrying rates of mental health problems). This theoretical paper hopes to apply the concept of anti-fragility developed by Nassim Nicholas Taleb─in particular one of its methods known as the Barbell Strategy─towards student learning, in the hope of a) maintaining a trajectory of academic excellence whilst b) avoiding the psychological pressures which usually accompany Asian students.


Inductively coupled plasma mass spectrometry using a laser ablation technique has been developed for the analysis of small inclusions of fused silica. A Q-switched pulsed Nd: YAG laser is fired at interesting sites of sample pieces with sizes of 10 - 40 mm. Ablated particles were introduced directly into the ICP. Preablation with the laser pulses was effective in removing the surface contamination; thus, 1-min preablation could be conducted at interesting sites before data acquisition. The intensity ratios of interesting elements to matrix element with corrections using the relative sensitivity factors obtained by a solution introduction method provide some semi-quantitative data concerning the samples. The established procedure has been applied to the analysis of black inclusions of fused silica. The results have indicated that the major constituent of the inclusions was Fe (oxides).


Three seismic shifts are under way in the wealth management industry, and the industry is ill prepared to adapt. The author describes each change and suggests how the evolution might transform—or destroy—the industry, depending on business choices made today.


A self-oscillating optical frequency comb generator (SOFCG) is demonstrated by applying the optoelectronic loop feedback to an optical frequency comb generator (OFCG) based on a dual-drive Mach–Zehnder modulator. The resulting SOFCG provides 23 comb lines with a frequency spacing of 11.84 GHz, corresponding to the oscillation frequency defined by the optoelectronic loop. The corresponding OFCG is also implemented by replacing the optoelectronic feedback loop with a microwave synthesizer at 11.84 GHz. A 94.8-GHz millimeter (mm)-wave signal is then generated by selecting two tones and heterodyning in a high-speed photodetector for both the SOFCG and the OFCG. The SOFCG system offers superior single sideband phase noise performance compared to the OFCG approach. Using the SOFCG developed here, it is possible to generate mm-wave signals up to 260 GHz, and this method is applicable to multiband radio-over-fiber (RoF) links. An RoF link is implemented with the SOFCG at 94.8 GHz. An LTE Advanced OFDM FDD 64-QAM signal of 20-MHz bandwidth is transmitted over a 1.3-m wireless distance.


In the domain of numerical computation, model order reduction approaches are more and more frequently applied in mechanics and have shown their efficiency in terms of reduction of computation time and memory storage requirements. One of these approaches, the proper orthogonal decomposition (POD), can be very efficient in solving linear problems but encounters limitations in the non-linear (NL) case. In this paper, the discrete empirical interpolation method coupled with the POD method is presented. This is an interesting alternative to reduce large-scale systems deriving from the discretization of NL magnetostatic problems coupled with an external electrical circuit.


Technological innovations are altering the lives of the poor, rich, nation's economics, and education globally. Hence, Ghana's commitment to formulate the ICT for Accelerated Development (ICT4AD) Policy in 2003 to achieve the transformative vision of competing favorably in the knowledge economy in addition to the introduction of ICT- related subjects in the Ghanaian schools to develop the human resources for indigenous knowledge development is laudable. However, instructional technologists feared that the Ghanaian ICT curriculum from basic to tertiary level might be too generic and lacking curriculum-specific integration literacy, thereby likely to widen the digital divide. To support Ghana's vision for ICT integration into higher education lessons, the current study sought to predict university graduates' integration literacy from cognitive constructs using partial least squares structural equation modeling (PLS-SEM) approach. The measurements and structural model fit indices were tested with SmartPLS Version 3. The results showed that students''goal-setting and need for achievement significantly predicted over 15% (R2 = .155) of ICT integrate skills. However, self-efficacy was not an important predictor (t = 1.74, p > .05) for students ICT integration literacy in the Ghanaian setting. We concluded that whilst graduates'goal-setting and need for achievement traits motivate them to acquire technology skills in the Ghanaian public universities, certainly, 85% of latent variables such as pedagogy, lecturers' computer integration competencies, and access remain unaccounted for per our structural model. The study recommends that career counsellors could design cognitive interventions to improve students' self-efficacy traits and educational administrators should encourage formative assessment by ICT instructors in their schools to enhance skills developments.


The collection of Prognostics and Health Management (PHM) data is very important for predictive maintenance of equipment (such as used in airplanes, automobiles, industrial machines). The data is provided by a variety of sensors that monitor the equipment, but the same data is used by the controllers that control the equipment. The deterministic functioning of the controllers which are typically run on multicore platforms is critical for certification purposes. The problem is then that the collection of the PHM data should interfere the least with the controllers operation. In this work, we implement a testbed using a quad-core ARM-based multi-core platform and report experimental results on the impact of the PHM data handling on the communication delay and execution delay of the critical controller tasks. We also provide insights about the system behavior.


Electrical stimulation of the nervous system has been employed to enhance the recovery of motor function produced by use-dependent rehabilitation, which is the current gold standard of treatment, following spinal cord injury. However, the therapeutic effects almost always rely on the sustained activation of muscles or neurons, making the benefits largely contingent on continued delivery of stimulation. In the present study, we describe a neuromodulatory intervention that combined intraspinal delivery of serotonergic agonists with use-dependent rehabilitation to restore motor function after a chronic moderate-to-severe cervical contusion in rats that produces impairments in upper-limb movements and dexterity. We show that targeted delivery of quipazine, a broad-spectrum serotonergic agonist, caudal to the lesion increased the effectiveness of physical rehabilitation, leading to substantially improved motor-recovery outcomes in severely-injured, but not moderately-injured, animals. Delivery of quipazine significantly augmented recovery of skilled reach and grasp movements after a severe injury, but moderately-injured animals received no additional benefit from quipazine over physical rehabilitation alone. This difference was perhaps due to a greater loss of serotonin after a severe injury and a resulting environment in which exogenously-applied serotonin can improve circuit function. Our experiments highlight an important role for serotonin in restoration of motor function that is dependent on the severity of the spinal cord injury. They also allude to a potential role for residual serotonin as a biomarker of injury severity. Remarkably, quipazine-mediated behavioral improvements persisted for weeks after termination of neuromodulator delivery, signaling repair of severely-damaged adult spinal circuitry that drives lasting motor recovery. Significance Statement We describe a neuromodulatory intervention that combined intraspinal delivery of serotonergic agonists with use-dependent physical rehabilitation, which is the current standard of treatment, to promote motor recovery after a chronic moderate-to-severe spinal-contusion injury. Our results show that targeted delivery of serotonergic agonists caudal to the lesion increased the effectiveness of use-dependent rehabilitation, leading to substantially improved motor-recovery outcomes in severely-injured, but not moderately-injured, animals. Notably, therapeutic gains persisted for weeks after termination of neuromodulator delivery—a finding that is both unique and clinically relevant—signaling plasticity induction and repair in chronically-damaged adult spinal circuitry. Our experiments provide important insights into serotonergic modulation of spinal circuitry and highlight a potential role for residual serotonin as a neurochemical biomarker of injury severity.

A cost-effective alternative for lowering carbon emissions from building heating is the use of flat-plate solar collectors (FPSCs). However, low thermal efficiency is a significant barrier to their effective implementation. Favorable nanofluids' thermophysical properties have the potential to increase FPSCs' effectiveness. Accordingly, this study evaluates the performance of an FPSC operating with Fe3O4-water nanofluid in terms of its thermo-hydraulic characteristics with operating parameters ranging from 303 to 333 K for the collector inlet temperature, 0.0167 to 0.05 kg/s for the mass flow rate, and 0.1 to 2% for nanoparticles' volume fraction, respectively. The numerical findings demonstrated that under identical operating conditions, increasing the volume fraction up to 2% resulted in an improvement of 4.28% and 8.90% in energy and energy efficiency, respectively. However, a 13.51% and 7.93% rise in the friction factor and pressure drop, respectively, have also been observed. As a result, the performance index (PI) criteria were used to determine the optimal volume fraction (0.5%) of Fe3O4 nanoparticles, which enhanced the convective heat transfer, exergy efficiency, and energy efficiency by 12.90%, 4.33%, and 2.64%, respectively.


In this paper, I used microprocessor and sensor and designed to improve the efficiency of the photovoltaic system the photovoltaic position tracker device, and compared the normal photovoltaic system of fixed form with the photovoltaic system of solar position tracked form. Moreover, compared the catalogue of solar cell module and the simulation through a mathematics modelling with the solar cell's characteristic interpreting and, composed an power conversion system with boost converter and voltage source inverter. Used the constant voltage control method for maximum power point tracking in boost converter control and, used the SPWM(Sinusoidal Pulse Width Modulation) control method in inverter control.


We consider the coupled system of the higher-order nonlinear Schrödinger equation and Maxwell-Bloch equations with pumping, which governs the nonlinear wave propagation in erbium-doped optical waveguides in the presence of important higher-order effects. We derive the Lax pair with a variable spectral parameter and the exact soliton solution is generated from the Bäcklund transformation.


A system is described that can be used for testing infrared focal plane cameras in situations where conventional blackbody sources are deficient. The system uses readily available components, electronics, and software. It can provide either a wide area or a point source of infrared flux that can be programmed to follow a prescribed temporal profile at higher rates than available from commercial blackbody sources and with excellent repeatability. Additionally, the system provides flux without suffering from the temporal noise characteristic of commercial, wide area, flat sheet sources that results from turbulence in front of the blackbody. The system consists of commercially available, rapid rise time infrared radiators, either coupled to an integrating sphere for broad area flux, or used individually with a pinhole and collimator as a point source. A programmable voltage supply provides the power versus time profile at frequencies to several Hertz. Transfer from a standard blackbody calibrates the flux le...


A method of scrambling a stream of data includes obtaining from the stream a succession of first sequences (29, 30) of blocks (P i) of data, reversing the order of the blocks (P i) in each of the first sequences (29, 30) of blocks to form respective second sequences (31, 37) of blocks of data, and encrypting the blocks in each second sequence (31, 37) of blocks using a cipher (E K) in block chaining mode, initialised with a respective initialisation vector (IV 3 , IV N) for each second sequence (31, 37) of blocks. For a succession of first sequences (29, 30) of blocks included in a unit (26) of data within the stream, at least one initialisation vector (IV N) for encrypting a second sequence (37) of blocks formed from a first sequence (30) of blocks in the unit is generated in dependence on at least one block in a preceding first sequence (29) of blocks of the unit.


Clonal lines of embryonal carcinoma cells have been established in culture from four independently‐derived transplantable teratocarcinomas of mice: three from strain C3H and one from strain 129/Sv. Cells from all lines retain the capacity to differentiate into a variety of tissue types both in tumors formed following the injection of cells into syngeneic animals and in vitro under appropriate culture conditions. Analysis of their G‐banded chromosomes indicated that the four lines have near‐diploid but not absolutely normal karyo‐types. The same chromosomal abnormalities were often present in more than one line.


ABSTRACT Resistance spot welding (RSW) process with protective coatings on advanced high-strength steels is a challenge. An ultimate tensile strength (UTS)1500 MPa grade hot stamping sheet steel(22MnB5) with Al–Si coating was employed for the RSW process in the present study. The effects of Al–Si coating on the microstructure of RSW joints and tensile-shear fracture behaviour were investigated. Strip-like Fe-(Al,Si) cladding on the surface of nugget tongues acted as the crack source and initiated the fracture. Two types of fatigue failure mode were observed: nugget pull-out with tearing of base material (BM) and eyebrow-shaped fracture along the BM width direction, corresponding to high and low loading levels, respectively. All fatigue fracture cracks were found to be originated along the Fe-(Al,Si) strip through the heat-affected zone.


Contrary to popular belief, John Carpenter's Halloween (1978) is not the first incarnation of the modern-day slasher film. That honour belongs to the small Canadian production Black Christmas (1974). This relatively unknown film is responsible for a genre that Informed dozens of Hollywood imitations and continues to be a popular part of contemporary cinema. Black Christmas is an example of how the formulaic nature of genre cinema does not necessarily restrict a filmmaker's means of political and national expression, because this film reflects a Canadian sensibility that doesn't exist in its Hollywood counterparts. That an influential cinematic genre originated with a Canadian film challenges the assumption that genre cinema opposes national cinema, and the constant exchange between cultural texts means that Canadian cinema can impact an institution as dominant as Hollywood. Black Christmas--a low-budget Canadian horror film directed by Bob Clark--follows a group of co-eds during the days leading up to their Christmas holidays. While living in a sorority house, these women repeatedly receive threatening phone calls and are eventually murdered by a man named Billy, whose true identity is never determined. This film takes place during a holiday, foregrounds the killer's subjective point of view, and features adolescent female victims stalked by a deranged male predator--all characteristics typically associated with the slasher film (1). Subjective camerawork is prevalent; the camera is often restricted to Billy's point of view so that his body remains hidden. The film begins with an extended sequence in which a shaky camera approaches the sorority house, accompanied by Billy's heavy breathing. The camera voyeuristically peers through an open window obscured by curtains, and we see male hands reach up to climb a trellis and scale the house. We see through Billy's eyes throughout the film, especially when he is killing the girls. Another slasher trope established in this film is the Final Girl. In virtually all slasher films there is a female character who knows what is going on, resists the killer's attacks, and survives until the end of the film. (2) Jess is such a character in Black Christmas. John Carpenter's Halloween was released four years after Black Christmas, but it is often recognized as the first slasher filing (3). Because it was so successful, its stylistic and narrative choices were imitated and developed by later Hollywood films. While Halloween did not necessarily copy Black Christmas, it gets the credit for starting the slasher tropes found in the earlier film. Carpenter's film also follows a group of adolescents, overwhelmingly female, who are killed by a psychotic male named Michael. It uses a subjective camera to reflect the first-person perspective of the killer, most prominently in its opening sequence that bears a striking resemblance to the opening of Black Christmas. Halloween begins with a long take from the killer's perspective, effectively concealing his Identity. The camera peers in the windows of a suburban home before entering the house. Next we see a long-sleeved hand grab a knife and murder the film's first victim. Halloween also features a Final Girl, Laurie, who is hyper-aware, fights off the killer's repeated attacks, and survives until the end of the film. There are significant differences between these two horror films, and even Bob Clark does not think Carpenter is guilty of plagiarism, as indicated by his interview on the 2002 DVD release of his film. However, he does acknowledge that his film influenced Carpenter's production. In the same interview he recalls a conversation he had with Carpenter in which he described a possible sequel to Black Christmas; this purely hypothetical films would have taken place during Halloween of the next year, and Billy would have broken out of a mental institution to resume his stalking of the sorority house. In Halloween, Michael escapes from a mental Institution to return to his former home and stalk those he associates with it. …


Abstract : The steam driven shipboard aircraft catapult systems have traditionally used qualified aviation piston engine oils (APEO's) to lubricate critical parts. The catapult launch systems first used products meeting the old military specifications MIL-L-6082 or MIL-L-22851. In 1995 the military specifications were canceled and replaced with the commercial SAE Standards (J-Spec's), J1966 and J1899. Unfortunately these APEO's are quickly becoming specialty products and are no longer available in bulk quantities which is how they are primarily used in the catapult launch systems. As a result Defense Logistics Agency - Energy (DLA-E) agreed to provide funding for a project to develop a new lubricant specification to address the shipboard aircraft catapult application. The goal of this program was to develop a replacement specification for the LA7 aircraft catapult launch system lubricant that would provide adequate performance and be readily obtainable in bulk quantities by the procurement community. The approach followed in this program was based upon a review of lubrication needs of the catapult systems, the fact the systems have traditionally used qualified aviation piston engine oils (APEO's) and that current APEO's are providing acceptable performance. Samples of current APEO's were obtained from the three primary APEO producers and subjected to a series of standardized, readily available performance tests Analysis of the data collected in this program lead to the development of a proposed set of tests and limits for a Commercial Item Description specification.


The Fe-based coatings were prepared by high velocity arc spraying technology(HVAS),high efficiency plasma spraying technology(HEPS),and detonation gas spray(DGS).Residual stress distribution and width at half height were measured by X-ray diffraction diffractometer.The microstructure and wear properties of the coatings were investigated by nano-tester and CETR wear tester.Results showed that the relationship of residual compress stress and wear properties of the coating is linear.The coating prepared by DGS has high hardness and excellent wear resistance.The main reason is that the DGS coatings have compress stress,high nano-hardness and compact structure.The fine structure and increment of distortion lattice of coating surface can improve wear resistance.


Aesthetic education makes full use of all aesthetic phenomena that exist in human society. In particular, the perception and understanding of beauty in work and the development of the human ability to make beauty part of the process and outcome of work. Music education is an important part of aesthetic education. By using music as an educational tool, music education develops special abilities and talents in specific types of art. In China, the integration between music examinations and aesthetic education brings a challenge to schools and public.How will schools put aesthetic subjects in the exam and what should be included in the exam? The paper introduced the background of the aesthetic education in China and discussed the roles of music in aesthetic education. To integrate the music education with the exams, the papers explores the paths of ability-originate exams, practical skills-originate exams and mind-developing originate exams, hoping to enlighten the public on the music course development in China.

So many books and articles have been written on the subject of how the poor live that it would seem perhaps, that there is little to add to the existing stock of knowledge on this question. There is, however, one aspect about which very little appears to be known, namely, the prevalence of borrowing among this dlass. There are several well-known methods to which recourse may be had when the family finances are depleted. The rent may be allowed to fall into arrears, the household possessions may find their way to the dealer or the pawnshop, or, if the family's standing, is sufficiently good, credit may be obtained from the local shopkeeper. But there is another method, far less well known and far more baleful in its results, viz., recourse to a money-lender. It was to ascertain how far this practice prevails and upon what terms the use of money can be obtained by the poor, that we undertook tha present inquiry. It is perhaps advisable first to say a word as to the method we adopted. It was obviously impracticable to make visits with the sole object of ascertaining whether the family had had recourse to a money-lender, since this question had to be led up to carefully, and anything in the nature of a house-to-house inquiry was therefore out of the question. The only pradticable method was to select households which were being visited in connection with some other object, and then, in the course of the usual inquiries into the family circumstances, to lead the conversation to the subject of borrowing. The names were taken mainly from two sources: the list of applicants for relief from the Prince of Wales's fund, including cases recommended for the workrooms, and the list of " dental cases " in connection with the School Care Committee. They were practically all householders, and might be described as fairly respectable, no occupants of furnished rooms being included. The district chosen was Limehouse. There were, of course, impediments to the inquiry in the atmosphere of secrecy and gloom which envelopes the subject of loans, and the people's disinclination to give any information concerning them is in striking contrast to the readiness—one might almost say the pride—with which pawntickets are displayed. White her hands are full of these credentials of respectability the applicant breaks out with, " N o , Miss, I never drink!" when the word

Air spring system was widely accepted for railway vehicle secondary suspension to reduce and absorb the vibration and noise. The low natural frequency ensures a comfortable ride and an invariably good stiffness. In this paper, the characteristics and durability test was conducted in laboratory by using servo-hydraulic fatigue testing system to reliability evaluation of air spring for electric railway vehicle. The experimental results show that the characteristics and durability of domestically developed productions are shown in good results. And to guarantee the adaption of air spring, the ride comfort and air pressure variation were measured in train test on subway line.


Enterohemorrhagic Escherichia coli (EHEC) serotype O157:H7 strains are associated with haemor raghic colitis and haemolytic uremic syndrome (HUS) in humans. Cattle are a reservoir of E. coli O157:H7. We studied the ability of bovine and human lactoferrin, two natural antimicrobial proteins present in milk, to inhibit E. coli O157:H7 growth and attachment to a human epithelial colorectal adenocarcinoma cell line (Caco-2). The direct antibacterial effect of bLF on E. coli O157:H7 was stronger than that of hLF. Nevertheless, both lactofer - rins had bacteriostatic effects even at high concentrations (10 mg/ml), suggesting blocking of LF activity by a yet undefined bacterial defence mechanism. Additionally, both lactoferrins significantly inhibited E. coli O157:H7 attachment to Caco-2 cells. However, hLF was more effective than bLF, probably due to more efficient binding of bLF to intelectin present on human enterocytes leading to uptake and thus removal of bLF from the extracellular environment. Inhibition of bacterial attachment to Caco-2 cells was at least partly due to the catalytic effect of lactoferrins on the type III secreted proteins EspA and EspB


We have received numerous remarks on the article about the IPSA Rome Congress, most of them complimentary. To quote Bob Hope, "We haven't been so overcome since Governor Faubus made us an honorary slave." But the last word remains with Professor James Pollock and we are pleased to quote his pertinent and sage remarks.
