Scoring the first goal in football could be crucial for winning a match. The aim of this study was to identify the performance indicators that influence the time the first goal is scored in high-level football matches. A total of 240 matches of the Portuguese Premier League played in 2009/10 season were analysed. The difference between the total number of goals scored and conceded during the competition up until the match considered, total ball possession time, shots on goal, set plays, disciplinary sanctions and substitutions were selected as predictor variables for the time the first goal is scored and loaded on a Cox regression model with time-dependent covariates. A greater goal difference (p < 0.05) and a larger number of shots on goal (p < 0.01) had a positive significant influence on the time the first goal was scored in the match by home teams; at the same time disciplinary sanctions (p < 0.01) and substitutions (p < 0.01) had a negative significant effect on the time of the first goal.


The contemporary United States health system lacks effective care coordination mechanisms and is fraught with perverse economic incentives. In fact, the problems are so severe that many say health care delivery is not a "system" at all. As a result of the lack of coordination and market failures, the quality of care most Americans receive is far below the level they should reasonably expect, given the ever-rising prices they pay. Despite the dire consequences of poor quality and unsustainable inflation, health care as we know it has proven remarkably resilient to external change efforts. Even the recently passed Patient Protection and Affordable Care Act (PPACA) will do very little to address the root causes of these problems precisely because there is no real system to be repaired. Doctors Thomas Lee and James Mongan of Partners HealthCare System in Boston provide their analysis of health care's failures and offer a clinical model to fix the chaos that keeps providers, insurers, and administrators from coming together to form an effective system. In Chaos and Organization in Health Care, Lee and Mongan begin with the standard case study of the patient that suffers unnecessarily at the hands of numerous, poorly coordinated health care providers. The personal tragedy arising from the chaos could have been prevented at any number of stages, but it was not. The authors then turn to the question: how did the care processes come to this disreputable and costly state-of-affairs? It is at this point that the book's two main viewpoints are drawn into juxtaposition—the physician and the administrator.


Abstract Abstract. Since homing pigeons, Columba livia , are able to orient homeward when released from familiar sites deprived of their sense of smell, they are thought to rely on other information acquired during previous experience with the release site. They may either follow a chain of landmarks to reach home without resorting to their sun compass (piloting mechanism) or fix their position from known landmarks at the release site and then select the home direction by the sun compass (map-and-compass mechanism). Which mechanism is used was investigated by testing the influence of a clock-shift treatment on the orientation of pigeons released from familiar sites. In four experiments, clock-shifted pigeons, some anosmic and some not, displayed an anticlockwise deflection in their initial orientation, as was expected on the basis of the fast clock-shift treatment applied. In all cases their bearing distributions differed significantly from those of non-shifted ones and the homing performances were significantly worse. Most of the clock-shifted birds made anosmic by a long-lasting treatment were lost. These results show that pigeons released from familiar sites rely on olfactory cues and known landmarks to determine the home direction, which is then selected using the sun compass. When rendered anosmic, they do not switch to a piloting mechanism but still use a map-and-compass mechanism, resorting to a mental map of familiar sites developed during previous training flights.


We describe a provenance model tailored to scientific workflows based on the collection‐oriented modeling and design paradigm. Our implementation within the Kepler scientific workflow system captures the dependencies of data and collection creation events on preexisting data and collections, and embeds these provenance records within the data stream. A provenance query engine operates on self‐contained workflow traces representing serializations of the output data stream for particular workflow runs. We demonstrate this approach in our response to the first provenance challenge. Copyright © 2007 John Wiley & Sons, Ltd.

The regression accuracy of the support vector regression(SVR) models strongly depends on a proper setting of its parameters.An optimal selection approach of v-SVR parameters was put forward based on chaos particle swarm optimization(CPSO) algorithm.A model based on v-SVR to predict the silicon content in hot metal was established,and the optimal parameters of the model was searched by CPSO.The data of the model were collected from No.3 BF in Panzhihua Iron and Steel Group Co..The results showed that the proposed prediction model has better prediction results than neural network trained by particle swarm optimization(PSO-NN),v-SVR and LS-SVR.The percentage of samples whose absolute prediction error is less than 0.03 by v-SVR model is higher than 90%,and it indicated that the prediction precision can meet the requirement of practical production.


External irradiation of the head and neck region in infancy and childhood is widely considered an important risk factor for thyroid disease and especially thyroid carcinoma. The data supporting this statement are derived from retrospective studies of patients with thyroid carcinoma 1,2 and from studies of groups of patients who received, or thought they had received, such irradiation. The latter studies generally have shown a 20% to 30% prevalence of palpable thyroid abnormalities, about half of these abnormalities being single or multiple thyroid nodules. 3-6 When surgery was done, about 30% of the subjects were found to have thyroid carcinoma (1.8% to 6.1% of the total number of subjects examined). Unfortunately, however, the specific criteria on which the recommendation for surgery was made were not stated. In the only study, that from the Michael Reese Hospital in Chicago, in which the size of the carcinomas was reported, two thirds were


In the title molecule, C16H16N2O2, the C—N bond lengths are 1.295 (5) and 1.300 (5) Å, which suggests that they are double bonds. The structure is stabilized by intramolecular O—H⋯N and C—H⋯N, and intermolecular C—H⋯O hydrogen-bond interactions.

Generative tasks, such as text generation and question answering, hold a crucial position in the realm of mobile applications. Due to their sensitivity to privacy concerns, there is a growing demand for their execution directly on mobile devices. Currently, the execution of these generative tasks heavily depends on Large Language Models (LLMs). Nevertheless, the limited memory capacity of these devices presents a formidable challenge to the scalability of such models. In our research, we introduce LLMCad, an innovative on-device inference engine specifically designed for efficient generative Natural Language Processing (NLP) tasks. The core idea behind LLMCad revolves around model collaboration: a compact LLM, residing in memory, takes charge of generating the most straightforward tokens, while a high-precision LLM steps in to validate these tokens and rectify any identified errors. LLMCad incorporates three novel techniques: (1) Instead of generating candidate tokens in a sequential manner, LLMCad employs the smaller LLM to construct a token tree, encompassing a wider range of plausible token pathways. Subsequently, the larger LLM can efficiently validate all of these pathways simultaneously. (2) It employs a self-adjusting fallback strategy, swiftly initiating the verification process whenever the smaller LLM generates an erroneous token. (3) To ensure a continuous flow of token generation, LLMCad speculatively generates tokens during the verification process by implementing a compute-IO pipeline. Through an extensive series of experiments, LLMCad showcases an impressive token generation speed, achieving rates up to 9.3x faster than existing inference engines.


In many‐body localized systems, propagation of information forms a light cone that grows logarithmically with time. However, local changes in energy or other conserved quantities typically spread only within a finite distance. Is it possible to detect the logarithmic light cone generated by a local perturbation from the response of a local operator at a later time? We numerically calculate various correlators in the random‐field Heisenberg chain. While the equilibrium retarded correlator A(t=0)B(t>0) is not sensitive to the unbounded information propagation, the out‐of‐time‐ordered correlator A(t=0)B(t>0)A(t=0)B(t>0) can detect the logarithmic light cone. We relate out‐of‐time‐ordered correlators to the Lieb‐Robinson bound in many‐body localized systems, and show how to detect the logarithmic light cone with retarded correlators in specially designed states. Furthermore, we study the temperature dependence of the logarithmic light cone using out‐of‐time‐ordered correlators.


Objective: To observe therapeutic effect of erythromycin in small dose on immature babies with feeding intolerance.Methods: 86 immature babies with feeding intolerance were randomly divided into two groups: the control group accepted the comprehensive therapy such as keeping warm,partial parenteral nutrition,positional therapy and so on;and the treatment group,who were dripped slowly with erythromycin 3 ~ 5 mg/(kg·d) besides comprehensive therapy for seven days.Results: Compared with that of the control group,the disease-duration of the treatment group were shortened obviously(t = 4.76,P 0.01),the amount of daily milk was increased obviously(t = 7.27,P 0.01)?Conclusions: The erythromycin in small dose can improve the feeding tolerance of immature babies.


This paper describes the development of software to perform three-dimensional crack propagation analyses. The software is based on the conventional finite element method with second order tetrahedral element and an automatic mesh generation software. Although hexahedral finite elements have historically been used in fracture analyses and methodologies to compute the crack parameters have been developed for the hexahedral elements, the authors successfully developed a VCCM (virtual crack closure-integral method) for the second order tetrahedral finite element in present research [1,2,3,4]. VCCM accurately computes the stress intensity factors based on an energetic approach. Use of the tetrahedral element allows us to adopt an automatic mesh generation program. Kawai et al [5] is developing a mesh generator for 3D crack analyses. The direction and rate of crack propagation are predicted based on the stress intensity factors and the shape of crack is updated. Hence, a software package containing the modules for mesh generation, for finite element analysis, for stress intensity factor evaluation, for predicting the rate and the direction of crack propagation and for updating crack configuration, is being developed. The outline of the software is illustrated in Fig. 1. At WCCM8, some example problems will be presented. Furthermore, VCCM for tetrahedral finite element has been extended for four-nodegeneralized tetrahedral finite elements with rotational and strain like degrees of freedoms at the corner nodes [6]. Some numerical results will be presented.

By 350 B.C. the Greeks knew Euclidean constructions for the regular polygons of 4, 8, 16,... sides and for those of 3 and 5 sides-the equilateral triangle and the regular pentagon. From these it was easy to construct regular polygons of 2c x 3, 2c x 5, 2c x 3 x 5 sides, where c is any positive integer, and the Greeks in effect showed how. They got no farther. Young Gauss proved that if N is of the form 2c or 2c times a product of different Fermat primes F,,, then there is a Eucidean construction for a regular polygon of N sides. This form of N is both necessary and sufficient for the possibility of a Eucidean construction....

A cost-effective alternative to manual data labeling is weak supervision (WS), where data samples are automatically annotated using a predefined set of labeling functions (LFs), rule-based mechanisms that generate artificial labels for the associated classes. In this work, we investigate noise reduction techniques for WS based on the principle of k-fold cross-validation. We introduce a new algorithm ULF for Unsupervised Labeling Function correction, which denoises WS data by leveraging models trained on all but some LFs to identify and correct biases specific to the held-out LFs. Specifically, ULF refines the allocation of LFs to classes by re-estimating this assignment on highly reliable cross-validated samples. Evaluation on multiple datasets confirms ULF's effectiveness in enhancing WS learning without the need for manual labeling.


Laser velocimetry is an optical technique used to make local measurements of mean velocity and turbulence in fluid flows without disturbing them. Laser velocimetry principles are briefly recalled; the optical and mechanical elements making up a velocimeter are described. Their purpose is to create two laser beams of equal intensity which are focused and crossed in a probe volume ¿ where a fringe pattern is formed; the light scattered by submicron particles passing through ¿ is collected by an optics rigidly connected to the emitting optics and focused on a photomultiplier. Among the various signal processing techniques, counters are now widely used, in connection with minicomputers. The different means used to determine the velocity sign and to measure simultaneously two components of the velocity are described; the simultaneous measurement of the three velocity components is more a matter of technology and cost than a theoretical problem. The modular operational velocimeter developed at ONERA is described; as examples of application, some typical results obtained in different aerodynamic flows are reported.


Experimental studies were carried out to investigate the performance of silver-based catalytic filter system (CFS) with regard to diesel exhaust emissions. The results were compared with those achieved with particulate filter (PF). The catalytic filter media consist of honeycomb substrate wash-coated with silver/alumina catalyst prepared by impregnation of commercial alumina beads with silver nitrate solution. Alumina rigidizer (Zircar ceramic, 99% alumina) was the binder used. The stable back pressure and high exhaust temperature observed on the engine when equipped with CFS indicate successful regeneration and satisfactory operation of the concept on the engine. Comparisons between the two emission reduction systems confirm that the CFS is effective at reducing diesel exhaust emissions except carbondioxide (CO2). As much as 51% reductions in particulate matter (PM), 42% in oxides of nitrogen (NOx), 63% in unburned hydrocarbon (HC) and carbonmonoxide (CO) were achieved with the CFS relative to the PF. The NOx reduction was observed in the same temperature range of the CO2 formation, implying the occurrence of the simultaneous removal of NOx and PM in an oxidizing atmosphere. It was shown that soluble organic fraction (SOF) and soot in PM are attributed to the reduction of NOx at lower and high temperatures, respectively. The oxidation of PM was enhanced by the coexistence of NO and O2. This method can be regarded as a combined process of PM trapping and catalytic reactions of PM oxidation as well as NOx reduction by SOF and soot. Therefore, it promises to be a desirable means of aftertreatment of diesel exhaust emissions.


It has been proved in the western developed countries that industrialization is very necessary to make its economy soar.With the industrialization,labor immigration is the problem which has been and will be dealt with by every country.Currently,in China,the main question during this immigration is the peasants entering the city.By using the fist-hand investigation materials,the present study tries to analyze the relation between peasants' richness degree and their entering the city.Our study shows that due to the different domestic net income for different peasants,there are not only common rules and trends but also differences in the cause and obstacles,the approach,the charge and earning when they enter the city.Considering the domestic net income differences,appropriate policies should be established to quicken the pace of labor immigration in China.


From the end of World War II when this city was occupied and divided, to the present, the governments of both West and East Berlin have been carefully preserving its historical role In the proliferation of the arts and conscientiously nourishing Berlin's tradition of cultural sophistication by devoting considerable funds to the arts. Today, the cities of West and East Berlin maintain active but totally separate cultural lives. West Berlin sees itself as a basis of democracy and free enterprise in the middle of the East German, hard-line Communist desert and must present itself as the shining outpost, as it were, of freedom. East Berlin, on the other hand, is well aware of its Important role as the capital of the Deutsche Demokratische Republik (DDR) and must present a bright and successful face for socialism. Both cities are under tremendous pressure to produce.


The relative photoresponse of certain types of neon discharge tubes to irradiation at different wavelengths has been investigated by spectrophotometric methods. The experimental results, using a large number of discharge tubes, are expressed graphically as relative photoresponse for equal energy of incident radiation plotted against wavelength. The curves show that the discharge tubes act like photoemissive cells with caesium alloy cathodes. It is suggested that the photosensitivity is due to the positive Joshi effect as well as to the presence of ceasium on the tube electrodes.

The Living Soil Association of Tasmania (LSAT) (1946-1960) pioneered the concepts of organic food and farming in Australia's smallest state, for the decade immediately after WWII. The LSAT was one of the world's first organisations to promote organic farming. It was preceded by New Zealand's Humic Compost Society (founded in 1941), the Australian Organic Farming and Gardening Society (1944), Australia's Victorian Compost Society (1945), and England's Soil Association (1946). The Tasmanian Association engaged, or was officially affiliated, with each of these four organisations. The LSAT actively courted and recruited a broad spectrum of organisations and government departments, particularly those with interests, or responsibilities, in agriculture, health, and education. The Association consistently sought a co-operative approach while avoiding a confrontational approach. An innovation of the LSAT was the provision for ʻJunior members'; the LSAT constitution included separate and specific Objects for Junior Groups, one of which was for school children to eat organic food.


ABSTRACT Purpose We identified the biophysical drivers of the main sources of on-farm greenhouse gases (GHG) emissions: enteric methane (CH4), manure CH4 and nitrous oxide (N2O), and field N2O and carbon dioxide (CO2). We explored the effect of selected management practices and their interactions on emissions mitigation and summarized findings from life cycle assessments of milk from dairy systems typical of the Midwest of the United States. Sources Peer-reviewed literature was the main source of data and information to construct this review. Synthesis Dry matter intake and feed conversion efficiency drive enteric CH4 production (g/d) and intensity (g/kg of milk), respectively. Dietary fiber and lipids influence enteric CH4 and dietary protein influences manure N2O. In the manure management chain, long-term storage of unprocessed liquid manure is a major source of GHG emissions, but the adoption of manure solid–liquid separation and anaerobic digestion substantially reduce the carbon balance of a farm. Amount, timing, and application mode of nitrogen fertilizer are keys to reducing N2O emission from fields. Reduced or no till, winter crop, and perennial crops increase soil OM content and reduce field CO2 losses. Variation in on-farm GHG emissions, which averaged 1.1 kg of CO2-eq per kilogram of milk, was associated more with specific management practices than with farm size or dairy system. Conclusions and Applications Adopting best nutritional, cropping, and manure management practices may reduce substantially on-farm GHG emissions in all dairy systems. Modeling and assessment methods must be improved to better account for interactions among system components and co-products of milk production.


Mutation of plant homeodomain finger protein 6 (PHF6) occurs in approximately 3% of acute myeloid leukaemia (AML) cases. Although it was reported to be associated with poor prognosis, it was not confirmed by other groups. Recently, propensity score matching has provided an effective way to minimise bias by creating two groups that are well balanced with respect to baseline characteristics, providing more convincing results, which has an advantage, especially for rare subtype studies. To provide further evidence on the role of PHF6 mutation, we performed a retrospective propensity score‐matched cohort study to assess the therapeutic responses and survival outcomes of AML patients with PHF6 mutation compared with those without PHF6 mutation after balancing age, sex and risk categories.


This paper proposes a distribution network fault identification method based on wavelet packet transform and semi-supervised support vector machine. Using wavelet packet transform obtain the zero-sequence current time-frequency matrix of power signals in each section of distribution network. Using the zero-sequence current time-frequency matrix and three-phase current signals construct the feature data. The semi-supervised support vector machine is trained by feature data with partial labels. The highest fault classification accuracy rate can reach 99.7%. When the proportion of valid label data is about 50%, the classification accuracy can reach 99.5%. The robustness of the algorithm is also verified.


The purpose of this study is to design and develop a cognitive diagnosis system for intelligent tutoring. The cognitive diagnosis system proposed in this dissertation is called PSCD (Production System for Cognitive Diagnosis). PSCD is intended for intelligent tutoring with possible relevance to decision aiding.
This dissertation is based on two assumptions. First, it is assumed that perspectives and methodologies of cognitive science provide a starting point for integrating decision-making studies and cognitive studies (Simon, 1979). Second it is assumed that integrating theories and building an integrated theory or theories into a cognitive architecture provide opportunities to realize practical applications (Newell, 1990). Basing on these two assumptions, the study attempts to integrate three theories of human information processing and to build the integrated theory into PSCD.
Three theories considered in this study are heuristic search, production systems architecture, and constructivism. These three theories act as constraints in setting the design specification of PSCD in the huge space of alternative designs. PSCD that are developed henceforth is applied to a counting task for initial validation, and to a transportation problem solving task which is the main task of this dissertation.


The structures of two salts of trimethylphenylammonium cation with iodide (1) and hydrogen sulfate (2) have been determined at 173 K. Crystals of both 1 and 2 are in the orthorhombic space groups P212121 and Pna21, with Z = 4 and cell dimensions a = 5.7671(7), b = 7.9353(6) and c = 22.258(2) for 1 and a = 9.3995(10), b = 13.0661(13) and c = 8.9860(13) Å for 2. In 1, the trimethylphenylammonium cation is hydrogen bonded and is restricted to nonclassical H2C―H...I and (π)C―H...π hydrogen bonds. The presence of hydrogen sulfate in 2 allowed further classical (O―H...O) and non-classical (C―H...O, H2C―H...π and (π)C―H...π) hydrogen bonding. Consequently, lattices of both 1 and 2 form supramolecular structures.


. Despite the developing industrialization, Vietnam is still an agricultural country with over 80 percent of the total area are agricultural land. However, this economic sector has not been effective organization, especially the control of the product quality and information flow. In this an article, Goal Programming (GP) approach has been suggested for solving a multi-objective mathematical model for the design of the fresh fruit product supply chain. Whereby, cost optimization is the first objective, the second objective is minimize delivery time and the third goal is to minimize the impact of the supply chain on the environment to ensure sustainable development. Because the statistics activities of agriculture in Vietnam is not really adequate, the application scope of this study focuses only on several fresh fruit products that the data collection is feasible.


Background and Methods: Most published studies have suggested that survival of de novo DLBCL with discordant BM involvement by small B cell lymphoma is indistinguishable from patients having a negative staging BM. The aim of the study was to investigate the incidence and clinical impact of BM involvement by concordant and discordant B cell lymphoma in patients with DLBCL seen in a single institution over a 5 year period (1\1\2000 – 31\12\2004). The cases were identified from pathology records and BCCA Lymphoid Cancer Database.

Results: The group of interest for this study comprised 652 patients with de novo DLBCL with staging marrow available for review. 60 of 652 (9.2%) of patients with DLBCL had concordant large B-cell lymphoma in their bone marrow. 523 (80.2%) were negative, 16 patients showed what we considered to be atypical lymphoid (ALH) infiltrates lacking definitive features of malignancy. In 50 patients (7.7%) the bone marrow showed discordant histology with predominantly small B-cells, some showing paratrabecular localization. In total there were five cases of TCRBCL in the study, three with marrow involvement. Furthermore, all 54 cases of primary mediastinal B-cell lymphoma (PMBCL) had a negative BM. Of the 652 cases with DLBCL with staging bone marrows available, merging the pathology and clinical databases resulted in 599 patients with complete clinical records. Of these, bone marrows were either not done or deemed inadequate in 101 cases. Therefore, there were 488 patients with DLBCL with an interpretable marrow of which 344 had advanced stage disease. Staging marrows in these patients were negative = 264, positive 41, discordant 28, and ALH 11. The overall survival and progression free survival were strongly affected by the IPI score for these 344 cases (P<0.00001) (see figure). Compared to those without BM involvement patients with concordant large B-cell lymphoma in their BM (n=41) had the worst outcome and those with discordant small B-cell lymphoma in the bone marrow (n=28) had an inferior but intermediate outcome (median survivals (months) = not reached;12 and 20, respectively).

Conclusion: Diffuse large B-cell lymphoma is a heterogenous group of lymphomas as demonstrated by gene expression profiling. Our data suggests that discordant low grade B-cell lymphoma in patients who have coincident DLBCL has a poorer prognosis and the presence or absence of BM disease has clinical significance. Though we had very few cases, TCRBCL show a higher incidence of BM involvement in keeping with the reported literature. The absence of marrow disease in PMBCL is consistent with recent data indicating it is a biologically distinct form of DLBCL.

The ancient town of Baldock occupies a shallow bowl in the hills that run west-southwest to east-northeast through North Hertfordshire, a northeastern extension of the Chilterns (Figure 1). It lies close to the source of the River Ivel, which flows northwards to join the Bedfordshire Ouse, but is not situated on a river. It is also at a road junction, with pre-Roman tracks from Braughing, Verulamium, and Sandy converging with the line of the Icknield Way to the southeast of the springs. It seems to have functioned as a local market centre, with evidence for small-scale craft production, although osteological evidence suggests that a proportion of the townspeople were agricultural labourers. Even so, there is evidence from all periods of a degree of personal wealth and literacy that places at least some of the inhabitants in the upper strata of Romano-British society. This view of the town contrasts with Stead's (1975, 128) dismissive comment that the town resembled an overgrown Little Woodbury Iron Age farm. Instead, the evidence now points to its success as a cult centre of at least sub-regional importance. Lead sealings that apparently name the settlement and its council (C·VIC—either Curia Vic... or C Vicanorum) demonstrate the presence of a curial class employing the trappings at least

This study aims to determine the response of investors before and after the stock split, to determine the differences in stock returns and stock trading volume before and after the company does stocksplit. The companies used in this research sample are from the manufacturing, mining, financial and agricultural sectors. The research method used is an expalanatory research method with a quantitative approach, with the data analysis technique of one sample t-test and paired sample t-test. The results of the study inform that: (a) on the eighth day there is investor response after the company does stocksplit. Investors respond negatively as evidenced by negative abnormal returns. (b) there is no significant difference between stock returns before and after stocksplit. (c) there is a significant difference between TVA before and after stocksplit.

Abstract.  The expectation‐maximization (EM) algorithm is a popular approach for obtaining maximum likelihood estimates in incomplete data problems because of its simplicity and stability (e.g. monotonic increase of likelihood). However, in many applications the stability of EM is attained at the expense of slow, linear convergence. We have developed a new class of iterative schemes, called squared iterative methods (SQUAREM), to accelerate EM, without compromising on simplicity and stability. SQUAREM generally achieves superlinear convergence in problems with a large fraction of missing information. Globally convergent schemes are easily obtained by viewing SQUAREM as a continuation of EM. SQUAREM is especially attractive in high‐dimensional problems, and in problems where model‐specific analytic insights are not available. SQUAREM can be readily implemented as an 'off‐the‐shelf' accelerator of any EM‐type algorithm, as it only requires the EM parameter updating. We present four examples to demonstrate the effectiveness of SQUAREM. A general‐purpose implementation (written in R) is available.


The trilobite family Cheiruridae is widespread in the Upper Arenig of Baltoscandia and has received much attention through time (e.g. Angelin 1854; Brogger 1882; Krueger 1994, 1995, 1996; Mannil 1958; Parnaste 2003; Pribyl, Vanĕk & Pek 1985; Schmidt 1881; Tornquist 1884). In spite of this only six Baltoscandian species and two subspecies have been described from the interval around the Volkhov-Kunda boundary (cf. Lamansky 1905; Mannil 1958; Schmidt 1881, 1907).


The mechanism and the kinetics of the short time metal deposition and dissolution has been analyzed on the basis of a model which includes transfer of ions across the double layer, diffusion of adions over the metal surface, and incorporation of ions into the lattice at steps one atom high. It is shown that it is possible to obtain data on the exchange current density of the reaction and on the equilibrium adion concentration from the initial portion of the potentiostatic transients. Steady‐state current density is analyzed. Conditions necessary for the surface diffusion of adions or for the transfer of ions across the double layer to be the rate‐controlling step in the over‐all reaction are formulated and discussed. Current density at each potential depends on distances between the steps suitable for the incorporation of adions into the lattice, which distances are related in turn to the dislocation density. On an ideal surface, without nucleation, the steady‐state current density should be zero. Conditions for two‐dimensional nucleation are analyzed and discussed.


SEVENTY YEARS OF CHANGING GREAT BOOKS AT ST. JOHN"S COLLEGE by William Scott Rule This dissertation examines a curricular approach at an institution that claims to maintain a liberal arts focus – that of the canon of Great Books as implemented as a formal curriculum at St. John"s College. My research question is: what enabled the Great Books program at St. John"s College to survive for over seventy years? The significance of this question can be seen by noticing that St. John"s College is the only college in the United States to have exclusively adopted reading the Great Books as its four-year curriculum. Other institutions that have experimented with a Great Books program prior to and since its introduction at St. John"s College have continued their existing programs as well, but many have limited their Great Books efforts to an honors course or general core requirement, if their Great Books effort survives at all. My dissertation is historical starting with the influencing factors leading to this curriculum"s introduction at St. John"s College in 1937. I then outline the implementation and document the changes to the list of Great Books comprising the program as it was updated over the subsequent seventy years as documented in St. John"s College"s academic catalogs from 1937 through 2008. I show that the list of Great Books required to be read by every student over the years has contained a consistent core while making slight adjustments. SEVENTY YEARS OF CHANGING GREAT BOOKS AT ST.

The lose control of detection report will be result in dissention of quality even dissention of legal duty. The low quality engineering will be under the umbrella of the irresponsibility of check and accept of construction, so the following coating must have the consciousness of self-protection and insist in detection to the quality of concrete.


and Traumatic Stress Studies (NKVTS) commissioned the Norwegian Knowledge Centre for the Health Services (NOKC) to conduct a systematic review about the factors promoting and hindering female genital mutilation/cutting (FGM/C), from the viewpoints of stakeholders residing in Western countries. The review would answer the question: What are the factors promoting and hindering the practice of FGM/C, as expressed by stakeholders residing in Western countries? Methods: We searched systematically for relevant literature in international scientifi c databases, in databases of international organisations that are engaged in aspects related to FGM/C, and in reference lists of relevant reviews and included studies. Additionally, we communicated with professionals working with FGM/C related issues. We selected studies according to pre-specifi ed criteria, appraised the methodological quality using checklists, and summarized the study level results in tables before performing an integrative evidence synthesis. Our conclusions were summed in a conceptual model. Results: We incluFactors promoting and hindering the practice of female genital mutilation/cutting (FGM/C)


For the M=G=1 uid model the stationary distribution of the buuer content is investigated for the case that the message length distribution B(t) has a Pareto-type tail, i.e. behaves as 1 ? O(t ?) for t ! 1 with 1 < < 2. This buuer content distribution is closely related to the stationary waiting time distribution W (t) of a stable M=G=1 model with service time distribution B(t), in particular when the input rate of the messages into the buuer is not less than its output rate c = 1. The actual waiting process of this M=G=1-model has an imbedded un-process which for 1 has the same probabilistic structure as the ! !n-process, the latter one being an imbedded process of the buuer content process. The relations between the stationary distributions U(t) and W (t) are investigated, in particular between their tail probabilities. The results obtained are quite explicit in particular for = 1 1 2. Further heavy traac results are obtained. These results lead to a heavy traac result for the stationary distribution of the ! !n-process and to an asymptotic for the tail probabilities of this distribution.


The primary objective of the present study was to identify how automated speed enforcement (ASE) affected the speeds that drivers choose on rural highways. The study specifically sought answers to the following two questions: (a) How did drivers respond to ASE on rural highways where live speed enforcement is limited? (b) What was the spatial extent of the speed reduction effects of ASE on rural highways? The research team compared speed data collected at various distances from seven sites in the Nanjing area of China where speed cameras were deployed. It was found that ASE significantly reduced vehicle speeds and speed violations in the vicinity of the locations where the speed cameras were deployed. However, ASE was not an effective way to reduce vehicle speeds on road sections beyond the area of influence of the speed cameras. The speed profiles developed in this study showed that the area of influence of a speed camera on a rural highway was generally less than 1 km. Drivers usually started to decelerate about 300 to 400 m before the speed cameras and recovered their original speeds about 300 to 400 m after the speed cameras. The findings suggested that without supplementation with other live speed enforcement efforts, such as mobile or stationary police patrols, elimination of speed violations on rural highways by the use of ASE alone would be difficult. A more realistic solution would be to deploy speed cameras at preselected potentially hazardous locations, such as intersections and horizontal curves, to help reduce speed violations.


This paper describes a unique undertaking that is underway at Houston Lighting and Power`s South Texas Project (STP). The paper presents an information upgrade project that uses expert system technologies to computerize design change procedures and to tightly integrate the resulting on-line, interactive procedures with the on-line information that design change activities use and generate. This effort will show how procedure computerization can leverage the large investments in plant data. The expected benefits include reduced costs and improved quality of design change work, plus a significant reduction in the burden of configuration management that comes from design changes. Both process computerization and the integration of process with data are being implemented at STP. This work is part of a major migration of information from a mainframe to a LAN platform. This paper will be of greatest interest to those involved in: (1) configuration management, (2) coordinating information to support design change procedures, (3) plant information management, and (4) business process reengineering.


We model the binding energies of rovibrational levels of the RbYb molecule using experimental data from two-color photoassociation spectroscopy in mixtures of ultracold $^{87}$Rb with various Yb isotopes. The model uses a theoretical potential based on state-of-the-art \emph{ab initio} potentials, further improved by least-squares fitting to the experimental data. We have fixed the number of bound states supported by the potential curve, so that the model is mass scaled, that is, it accurately describes the bound state energies for all measured isotopic combinations. Such a model enables an accurate prediction of the s-wave scattering lengths of all isotopic combinations of the RbYb system. The reduced mass range is broad enough to cover the full scattering lengths range from $-\infty$ to $+\infty$. For example, the $^{87}$Rb$^{174}$Yb system is characterized by a large positive scattering length of $+880(120)$~a.u., while $^{87}$Rb$^{173}$Yb has $a=-626(88)$~a.u.. On the other hand $^{87}$Rb$^{170}$Yb has a very small scattering length of $-14.5(1.8)$~a.u. confirmed by the pair's extremely low thermalization rate. For isotopic combinations including $^{85}$Rb the variation of the interspecies scattering lengths is much smoother ranging from $+39.0(1.6)$ a.u. for $^{85}$Rb$^{176}$Yb to $+230(10)$ a.u. in the case of $^{85}$Rb$^{168}$Yb. Hyperfine corrections to these scattering lengths are also given. We further complement the fitted potential with interaction parameters calculated from alternative methods. The recommended value of the van der Waals coefficient is $C_6$=2837(13)~a.u. and is in agreement and more precise than the current state-of-the-art theoretical predictions (S. G. Porsev, M. S. Safronova, A. Derevianko, and C.W. Clark, arXiv:1307.2654 (2013)).


Earlier work on U.S. import demand suggest that structural change may have occurred sometime in the mid-1960s. Since this evidence was based upon a somewhat arbitrary splitting of the sample period, the dating of change is uncertain. In this paper we investigate the question of structural change for both U.S. imports and exports, using a procedure that lets the data determine if and when structural change may have occurred. We find weak evidence of structural change for imports in the mid- to late 1960s and much stronger evidence in 1972:1 and thereafter. There is no evidence of structural change for exports.


Crystalline Er2O3 thin films were epitaxially grown on Si (001) substrates. The dielectric constant of the film with an equivalent oxide thickness of 2.0 nm is 14.4. The leakage current density as small as 1.6 X 10(-4) A/cm(2) at a reversed bias voltage of -1 V has been measured. Atomically sharp Er2O3/Si interface, superior electrical properties, and good time stability of the Er2O3 thin film indicate that crystalline Er2O3 thin film can be an ideal candidate of future electronic devices.

The article reveals the essence of the concept of "circular economy" and offers its own definition of this concept as a way of economic development, where the value of products, materials and resources is preserved as long as possible and waste is significantly reduced or even eliminated. The implementation of the circular economy model, which is based on the R-principles of its implementation, is considered. It is substantiated that the main areas of development of the circular economy of the region are construction, mobility and transportation, food, products and services. The benefits of implementing a circular economy in the region are outlined. Keywords: cyclicity, circular economy, region, circular economy model, advantages.


MTV cannot be counted among the champions of European civilization. In fact, its instincts are so far to the left, that an accurate expression of its red shift values would require complex mathematics. Fortunately, and as Eric Owens pointed out in his November 2000 article for American Renaissance, "The New Nationalist Music," not all modern popular music comes from the left of Trotsky. Mr. Owens' article provided a useful overview of the various nationalist music scenes that emerged since the 1970s, each offering an alternative subculture for young generations disillusioned by the mainstream. Much has happened since 2000, however, and at least some of the music scenes surveyed by Mr. Owens have seen considerable growth and gone on to spawn new scenes. It is worth re-visiting Mr. Owens' topic, and shedding some light on what has driven the growth of nationalistic music during the past decade. Although Mr. Owens discussed several genres (Oi!, Apocalyptic Folk, Nationale révolutionaire, and Black Metal), I will focus only on Black Metal. This is my area of expertise and, most


A GIS is used to study the surface water in Ibadan. Data which relates to the physical parameters of the study area, were used in this study. These included a SPOT-multispectral imagery, topographic and geological maps of Ibadan, which were analyzed and interpreted.
The enhancement of the digital image (SPOT- multispectral imagery) was by linear contrast stretching in standard colour composite showing vegetation as red, settlement as blue, and water bodies as black, thus making it possible to vectorize the raster dam of Eleyele, by manual digitizing for GIS processing.
Spatially overlaying objects of hydrographic network features on the digital elevation model (DEM) and the geologic map, revealed that the Eleyele valley from the topographical point of view has all the topographic and physical structures conducive for the location of an effective dam. The geological conditions are adequate for proper water impoundment while the non-porous nature of the rocks and absence of faults in the enclosing rocks ensure that the impounded water is retained.

Background: Benign prostatic hyperplasia (BPH) is characterized by the nonmalignant overgrowth of prostatic tissue surrounding the urethra, ultimately constricting the urethral opening, and giving rise to associated lower urinary tract symptoms.

Objectives: Diagnosis of BPH is made based on histologic examination of prostatic tissue. This study aimed to evaluate the clinicopathological and cystometric changes in BPH patients.

Materials and Methods: In this study, 61 elderly males who were suffering from clinical BPH were included. Patients of different age groups ranging from 50 to 80 years and more were considered. All patients were undergone clinical, urine examination, and ultrasound scan was performed to confirm the hypothesis. The patients were divided into three subgroups according to the International Prostate Symptom Score as mild, moderate, and severe.

Results: In mild group of patients, the mean compliance was 44.11; in moderate, it was 21.90; and in severe group, it was 17.54.

Conclusion: This study concluded that as severity of bladder outlet obstruction increases, the compliance of bladder decreases. Cystometric evaluation of bladder compliance should be an essential part in pre-operative evaluation of symptomatic BPH patients.


A novel route involving atmospheric pressure chemical vapour deposition (APCVD) is reported for coating Nb2O5 onto glass substrates via the reaction of NbCl5 and ethyl acetate at 400-660degreesC. Raman spectroscopy is shown to be a simple diagnostic tool for the analysis of these thin films. The contact angle of water on Nb2O5-coated glass drops on UV irradiation from 60degrees to 5-20degrees. XPS Analysis showed that the Nb:O ratio of the film was 1:2.5. Glancing angle X-ray diffraction showed that all films were crystalline, with only a single phase being observed; this has some preferred orientation in the (201) plane of Nb2O5. The niobium(V) oxide materials show minimal photocatalytic ability to degrade organic material.


Rhizomes of Zingiber zerumbet collected from their natural habitat and reported earlier to have high zerumbone content were selected for isolation of endophytes. Biochemical and molecular characterization using 16S rRNA sequencing of the endophytes identified the isolates as belonging to genus Klebsiella, Pantoea and Enterobacter. Isolate designated ZzKSD8 identified as K. aerogenes yielded maximal antagonistic activities against P. myriotylum determined as 83.5% ± 0.77. Volatile metabolites produced by ZzKSD8 caused absolute impairment of P. myriotylum hyphal growth compared to control (23.9 ± 0.37 cm). Volatile metabolites were extracted from 48 hour grown stationary phase ZzKSD8 cultures using absolute methanol, ethyl acetate and ethanol (60% v/v). GC-MS metabolite profiling detected alkanes and fatty acid methyl esters as the predominant constituents in the solvent extracts. Major constituents included methyl palmitate (31.37%), methyl stearate (18.57%) and cyclopropaneoctanoic acid, 2-hexyl-, methyl ester (17.05%) in methanol extract; alkanes like tetratetracontane (13.18%) and 2-methyloctacosane (12.10%) in ethyl acetate extracts and 4,22-sigmastadiene-3-one as major metabolite (22.51%) and stigmast-5-en-3-ol, (3.beta) (17.40%) in ethanol extract. Identified metabolites reported to modulate defense strategies in plants against phytopathogens makes ZzKSD8 a potential candidate for development of biological alternatives to control soil-borne soft-rot disease.


We propose and examine a theory of how the context of the political climate and incumbency interact to affect candidate strategies and their impact on candidate evaluations and the vote in presidential elections. From this theory, we generate four hypotheses. Two concern the difference between elections in which the incumbent runs as opposed to open seat races with a successor in-party candidate. The other two hypotheses concern the difference in evaluations of incumbents and successor candidates in open seat elections. The results indicate that open seat elections are less reflective of the political climate than incumbent elections, that incumbents experience higher highs and lower lows than successor candidates, that evaluations of successor candidates tend to be more muted representations of evaluations of incumbents, and that the vote in open seat races depends more heavily on how voters judge the successor candidate rather than the incumbent leaving office. The contextual campaign made a substantial difference in 2008, allowing John McCain to distance himself from the unpopular President Bush and to do significantly better in evaluations and at the polls than the incumbent would have.


It is proposed to study the learning and contribution of the social educator to human formation and its regulation as a professional of the educational area. It is a study of non-formal education and the role of the social educator, as well as its relationship with public educational policies and socio-cultural phenomena. They aim to present the historical order and evolution of the analysis of public policies and their emergence, as well as their importance not only in Brazil, but also for the world within the field of education. The discussions about the quality of education in Brazil raise questions about teacher education, financing, physical structure of the building, pedagogical practice, socioeconomic profile of the student and school management - elements considered determinants of the quality of education in a school unit. Within the framework of the discussions are the external evaluations as a way of qualifying the schools and the education systems in the country. It is based on the epistemological perspective on education. It is an exploratory and descriptive research, of qualitative approach, according to socio-cultural studies, evaluation of public policies; Analysis and description of actions of education. The aim is to verify the extent of public policies to promote dignity in social and ethnic minorities, at national level, in addition to their participation in the emancipation of the individual and the promotion of the quality of life and human dignity.


While three-dimensional techniques are widely used in the turbomachinery industry, a mean-line approach remains at the core of multidisciplinary design and analysis. Combining rules of design, conservation laws, and experience permits narrowing down design options, outlining geometry, and evaluating results in an effective and consistent manner. This paper reports on a project initiated by the original equipment manufacturer (OEM) to develop a versatile close-coupled stage design system for centrifugal compressor stages. This mean-line design suite is based on flexible system architecture including a combination of in-house and commercial analysis and design software modules. Inter-code data transfer and user interfacing are facilitated through a master spreadsheet and a commercial director integration program. Significant outputs available from this design system include rule-based solid models and selective flow path component optimization. Examples of both are presented in this paper. This work was done as part of an undergraduate cooperative work-study program. The cooperative education program offers value to both industry and academia. The educational and commercial implications of this project are discussed.Copyright © 2011 by ASME


The non-isothermal crystallization process of polyethylene terephthalate/polybutylene terephthalate(PET/PBT)blends and the effect of the cooling speed on crystallization behavior of PET/PBT/Talc/nucleating agent(P250)were studied by differential scanning calorimeter(DSC).The Jeziorny,Ozawa and Mo methods were employed to analyze the DSC data.The results showed that:the relative crystallinity rate(Xc)of PET/PBT blends decreased,the crystallization rate was increased by adding Talc;the effect of PET/PBT/Talc blends with the nucleating agent was better;the crystallinity of PET/PBT/Talc/P250 blends decreased,the crystallization rate was increased while the cooling rate increased;the Jeziorny and Mo methods could describe the non-isothermal crystallization process well,while Ozawa mothod was a little localized.


Based on the deepening research of the Paleotethyan tectono paleogeographic framework in western Yunnan, we have suggested a scale of time and space standard concerning the differentiation between archiopelagic sea and archiopelagic ocean. According to the comparison study of the Paleotethyan sedimentary geology among northwestern Tibet, northern Thailand and western Yunnan, we demonstrate that the Changning Menglian belt of western Yunnan elongates towards north to the Gangmacuo suture zone of northwestern Tibet and towards south to the cryptic suture zone in northern Thailand respectively. The Nan Uttaradit suture zone of northeastern Thailand is probably elongated to north and hidden under the Mesozoic Cenozoic red beds of Simao basin. Of course, there is no evidence concerning a stable Simao block during the Paleotethyan stage. Tectono sedimentary melanges consist of oceanic bedded cherts, seamount carbonates and passive margin clastics that are found in the Mae Sariang zone of northwestern Thailand; moreover, Early Carboniferous and Late Triassic (Carnian) radiolarian faunas are also discovered in previously so called "Devonian" strata of this area. It indicates that the tectono paleogeographic framework of eastern Paleotetethys probably exists as the Gemini type archipelagic ocean with double main branches. Mae Sariang zone probably connects northward the Luxi ophiolitic melange zone between Baoshan and Tengchong blocks in western Yunnan. The discovery of Jurassic radiolarian fauna in previously so called "Late Triassic" Hagong Formation in northwestern Yunnan also inspires the variety and complexity of geological history in southeastern Asia during the transitional stage between Paleaotethys and Neotethys.


Auctioneers who have an indivisible object for sale and believe that bidders are risk neutral can find the recipe for an optimal auction in Myerson (1981); auctioneers who believe that bidders are loss averse can find it here: An optimal auction is an all pay auction with minimum bid, and any optimal mechanism is all pay.


The riding simulator that we have developed consists of a horse-like body, swing mechanisms, a control unit, and an imaging device, and realizes the three basic riding motions of real horses-namely, walk, trot, and canter. In addition, a rider can experience the feeling of real horse riding by controlling the movement of the horse, such as start, stop, and change of the riding pace, and with the aid of an image of the horse's riding course displayed on a screen in front of the rider.

Background & Aims: The main aim of the study was to assess the impact of COVID-19 pandemic on surgical education for the medical students. Methods: Final year medical students of Manchester University who had completed their surgical placement were invited to participate in the study. All participants were given a questionnaire through the University social media platform. Responses to the questionnaire were analysed to evaluate the outcome. Results: The surgical education for medical students during the pandemic was analysed on various aspects like ward-based learning, out-patient clinic, theatre sessions and various teaching methods that were employed. Sixty-four percent of students felt that COVID-19 had a significant negative impact on ward-based learning, while forty percent felt that their learning in out-patient clinics was affected. All of them had an opportunity to attend at least one theatre session during the pandemic. On the other hand, forty eight percent of students felt that the theatre learning activities were adequate during this period while twenty four percent of students remained neutral in their view. Webinars remained the most attended teaching sessions with about eighty-eight percent of students receiving some form of online teaching, while simulation-based approach remained the most popular among the students. Conclusion: Ward based learning has been significantly affected by the pandemic. Students were satisfied with the learning opportunities in theatre. Newer methods including actor-based simulation using MS teams, out-patients' clinics and simulation-based assessments were regarded the best teaching modalities and were highly appreciated by students.

Using sintering dust as a raw material, selective catalytic reduction (SCR) catalysts were pretreated with water and acid washing (HF, HCl, HNO3 and H2SO4) and then modified by different metal oxides (Ce, Cu, Eu, Nd and Mn) with an impregnation method. Based on this, the catalyst was supported by ZrO2, Al2O3 and TiO2. The catalysts were ascertained by various characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and N2 adsorption–desorption analysis. The results showed that the main component of sintering dust was iron oxide (> 50 wt%), which is a feasible material for fabricating SCR catalysts. The catalysts pretreated by HF and modified by CeO2 improve the denitration efficiency. When modified with 10 wt% CeO2, the Ce10-PSDCHF catalyst sample exhibited the best NOx conversion rate, reaching 76.4% at 280 °C. The catalyst modified by ZrO2 was dispersed well and had best denitration efficiency. The denitration efficiency of SCR increased with the increase in ZrO2 loading and the NOx conversion rate of 0.25-Ce10-PSDCHF/ZrO2 catalyst reached 85% at 280 °C. The modification and support of metal oxides improve the denitration efficiency, which makes the sintering dust have promising industrial application prospects. This work would be timely technical guidance and valuable insights for the application of sintering dust. Extended author information available on the last page of the article 2300 D.

There's a better way to configure complex transportation networks and fill them with the right sort of hauling capacity. The caveat, however, is that the sheer size and complexity of these networks means technology is required to perform the analytics that enable harvesting the value. Here's how to get it done.

The fluctuation of received signal strength (RSS) caused by environmental changing and heterogeneous devices severely degenerates the performance of WiFi fingerprint-based positioning methods. Deep Domain Adaptation (DDA) in transfer learning has proven to be an effective strategy to deal with this situation. However, the existing DDA methods show limited improvement in positioning accuracy in presence of the two factors simultaneously. In this study, we propose a new deep adaptation networks by adopting the joint constraints of mean and covariance to reduce domain discrepancy, which shows an excellent adaptability to environmental changing and heterogeneous devices. To further improve the robustness of our network, we design an exponential moving average method to update the parameters of the network, which can be further updated by unlabeled data from target domain, which is highly consistent with the actual application scenario and has practical significance. Experiment results show that the proposed model can reduce domain discrepancy effectively, and achieve lower positioning error than some other existing methods in real complex indoor environments.


Background Laparoscopic ventral hernia repair has become a widely used technique. Objective This study evaluates the outcomes of laparoscopic ventral hernia repair with and without fascial repair, with particular reference to complications, seromas, and early recurrence. Patients and methods A total of 177 patients were divided into three groups. Group I underwent laparoscopic [intraperitoneal onlay mesh (IPOM)] hernioplasty without repair. Group II underwent laparoscopic IPOM hernioplasty with intracorporeal repair. Group III underwent laparoscopic IPOM hernioplasty with transfacial closure using PDS loop. Patients were followed for 6 months for early postoperative morbidity, including seroma formation, whereas the secondary end points were the adequacy of transfacial repair and its effect on early hernia recurrence. Conclusion Transfacial suture closure of hernia defect is the simplest method of the hernia repair and effective with less incidence of seroma and early recurrence as compared with nonfascial repair technique. Defect closure strengthens the abdominal wall by regaining its whole function and gives more space for mesh insertion. Whatever technique used for ventral hernia repair, obesity is still the most important risk factor for seroma and hernia recurrence.


Objective To investigate the clinical effect and value of intraoperative and postoperative intraperitoneal thermic chemotherapy in advanced colorectal cancer in elderly patients.Methods In this series,68 patients received intraoperatitve and postoperative intraperitoneal thermic chemotherapy(treatment group) and other 81 received only saline water lavage after radical resection(control group).Isolated cancer cells(ICC)in the peritoneal fluid,hepatic function,blood cell analysis and prognosis were compared between the two groups.Results The positive rate of ICC was 3.1% in treatment group and 12.8% in control group(P0.05).Hepatic function and blood cell analysis did not show significant difference between the two groups.The 1,2,3-year survival rates were 98%,86%,68.8% and 96%,62.6%,48.1%,respectively in treatment and control groups.There were significant differences in the 2,3-year survival rates between the two groups(P0.05).Conclusion Intraoperative and postoperative intraperitoneal thermic chemotherapy is safe and effective.It can kill isolated intraperitoneal cancer cells,reduce peritoneal recurrence after radical resection,and improve the prognosis in elderly patients with colorectal cancer.


Future improvements to jet engine performance will require materials which are lower in density and can withstand higher temperatures; thus increasing the thrust-to-weight ratio and the engine efficiency. The intermetallic compound IB-NiA1 is a prime candidate for this new high temperature material. This intermetallic offers a low density, a high melting temperatme, and excellent oxidation resistance, but exhibits poor creep resistance. The creep resistance may be improved by composite engineering with refractory metal fibers and of particular interest to the present study are the refractory composites formed by eutectic solidification. There are three known refractory metals which may be solidified as a eutectic with I~-NiAI: W(1), Mo(2,3), and Cr(2-5). Another useful refractory metal addition would be Re. Indeed, a-Re fibers would offer greater high-temperature strength than either Mo or W in the temperature range of 950 to 1250°C(6). This is in part a result of the close packed hexagonal crystal structure of a-Re. The mechanical properties of B-NiAI alloyed with Re via a powder metallurgy technique have been studied by Vedula et al.(7). This study revealed that the addition of Re to 13-NiAI did not produce an extended solid solution or a new phase equilibrium and the consolidated alloys exhibited microstructures of 13-NiAI with a dispersion of a-Re particles. One possible explanation for this result is that Re forms a quasi-binary eutectic isopleth with 13-NiA1. Thus, the purpose of this study was to determine if a composite with a matrix of 13-NiAI and fibers of a-Re could be produced by eutectic solidification and if so, to determine the nature of the quasi-binary phase diagram.

In this article the usefulness of the enzyme phi29 DNA polymerase and the principle of rolling circle amplification (RCA) for creating single‐stranded DNA (ssDNA) nanostructures is described. Currently we are working on the spatial orientation of a growing ssDNA molecule during its RCA‐based synthesis by the application of a hydrodynamic force. Starting at an immobilized primer at single molecule level, the aim is to construct a nanostructure of known location and orientation, providing multiple repeating binding sites that can be addressed via complementary base‐pairing. Proof‐of‐principle experiments demonstrate the potential of the enzymatic reaction. ssDNA molecules of more than 20 μm length were created at an immobilized primer and detected by means of fluorescence microscopy.


The so-called 'small-world phenomenon', observed in many real-world networks, is that there is a short path between any two nodes of a network, whose length is much smaller that the network's size, typically growing as a logarithmic function. Several mathematical models have been defined for social networks, the WWW, etc., and this phenomenon translates to proving that such models have a small diameter. In the first part of this thesis, we rigorously analyze the diameters of several random graph classes that are introduced specifically to model complex networks, verifying whether this phenomenon occurs in them. In Chapter 3 we develop a versatile technique for proving upper bounds for diameters of evolving random graph models, which is based on defining a coupling between these models and variants of random recursive trees. Using this technique we prove, for the first time, logarithmic upper bounds for the diameters of seven well known models. This technique gives unified simple proofs for known results, provides lots of new ones, and will help in proving many of the forthcoming network models are small-world. Perhaps, for any given model, one can come up with an ad hoc argument that the diameter is O(log n), but it is interesting that a unified technique works for such a wide variety of models, and our first major contribution is introducing such a technique. In Chapter 4 we estimate the diameter of random Apollonian networks, a class of random planar graphs. We also give lower and upper bounds for the length of their longest paths. In Chapter 5 we study the diameter of another random graph model, called the random surfer Web-graph model. We find logarithmic upper bounds for the diameter, which are almost tight in the special case when the growing graph is a tree. Although the two models are quite different, surprisingly the same engine is used for proving these results, namely the powerful technique of Broutin and Devroye (Large deviations for the weighted height of an extended class of trees, Algorithmica 2006) for analyzing weighted heights of random trees, which we have adapted and applied to the two random graph models. Our second major contribution is demonstrating the flexibility of this technique via providing two significant applications. In the second part of the thesis, we study rumour spreading in networks. Suppose that initially a node has a piece of information and wants to spread it to all nodes in a network quickly. The problem of designing an efficient protocol performing this task is a fundamental one in distributed computing and has applications in maintenance of replicated databases, broadcasting algorithms, analyzing news propagation is social networks and the spread of viruses on the Internet. Given a rumour spreading protocol, its spread time is the time it takes for the rumour to spread in the whole graph.


The objective of the system is to design and analyse PID controller for DC servo control system. The aim of the system is to develop proportional, integral and derivative controllers for the DC servomotor of the second order system. At first, MATLAB simulation is used for system unit step response of PID controller. The step response is evaluated the performance of a tuning servo system. It is error-driven, in other words, there must be a difference between the input and output before the servo will begin moving to reduce the error. PID based servo loop also called a compensator that has the job of keeping the DC servomotor at the desired position. Moreover, the characteristics and operation of control system is also analysed by using Ziegler–Nichols Tuning algorithm. Simulation results of the PID controller by using MATLAB program are described in the project. Then, PID controller circuit can be designed and calculated from software simulation results of closed loop second order feedback control system. PID controller circuit for second order dc servo motor control system is analysed by Proteus software. Keywords— PID controller, step response, DC servomotor, Ziegler–Nichols Tuning algorithm


ABSTRACT The objective of the present study was to develop a methodology to obtain the enriched fraction of ram seminal vesicle protein 14 (RSVP14). The study was developed using Morada Nova rams, from which semen samples were collected weekly. Seminal plasma proteins were precipitated with cold ethanol, and then 6.15 mg/mL of total proteins were subjected to liquid gelatin affinity chromatography using a Gelatin-Sepharose matrix coupled to an automated chromatographic system. Proteins were eluted into four fractions (A, B, C, [...]


We describe the Simple Greedy Matrix Completion Algorithm providing an efficient method for restoration of low-rank matrices from incomplete corrupted entries.
We provide numerical evidences that, even in the simplest implementation, the greedy approach may increase the recovery capability of existing algorithms significantly.


This paper is focuses on thunderstorms and hails in an attempt to address one of the most pressing issues in the debate on climate change, which is to understand sources of extreme meteorological and climatological phenomena. The study used records of obser- vations at 24 weather stations covering the period 1949 - and thunderstorm details from eight stations in the period 1885 - The study identified no clear trend in the number of days with thunderstorms or with hails during the study period. For both phenomena there is a strong regional variation, both annually and in the long-term. This kind of spatial variation in the occurrence of thunderstorms and hails is characteristic of these phenomena in many areas of the world ( Changnon 1988; Brazdil et al. 1998; Kuleshov et al. 2002 ). In Poland most of the stations that recorded a decrease in the number of days with thunderstorms after 1949 were found north of the line connecting Mt. Śniezka in the southwest and the town of Suwalki in the northeast and the greatest decrease in this number was recorded in Slubice at 1.3 days per 10 years. A trend to an increase in the number of days with thunderstorms was observed south of the line. The greatest increase in the number of days with thunderstorms was recorded in Wlodawa ( 1.7 days per 10 years ), Lesko ( 1.6 days ) and Katowice ( 1.1 days ). Addition- ally, the study revealed that during the second part of XX century there was an increase in the number of days with thunderstorms in the cool half of the year at most of the stations involved. The pattern was particularly strong to the south of the Śniezka-Suwalki line and in Szczecin. With the time scale expanded to the period 1885 - 2008, the changes are weaker, which clearly suggests that any patterns that emerge depend on the study period chosen. The spatial and temporal variabilities in the two phenomena are caused by the dominant types of atmospheric circulation and by regional differences in environmental conditions. Numerous authors have also suggested a link between changes in the occurrence of thunderstorms and hails and macroscale changes in the atmospheric circulation ( Kamyshanova 1974; Changnon 1985 ). On the one hand, in some regions the influence of characteristic synoptic situations


This paper presents an analysis of fractional order PID (FOPID) controller for first order system model with and without time delays. The proposed strategy can be viewed as replacement of integer order integrator with a fractional integrator when anti-windup scheme is used which removes the reset windup resulting in reduced set point change. In order to have satisfactory parameter's tuning of the fractional order controller (FOC), an iterative optimization method has been used which is based on minimization of a quadratic cost function. This cost function is defined as weighted sum of squares of control input which moves and sum of the integral squared error (ISE) between the time response of the reference model and the fractional system with FO-PID controller. The resulting closed-loop system shown exhibits features of robustness to process gain variations and also the step response with good damping. Simulation results have been presented with analysis that illustrates the effectiveness of proposed algorithm.


There has been a paradigm shift globally from high combustion rates of all human activities that contribute to global warming. Environmental awareness has been increasing rapidly over the past years. In these regards, Evotherm, which is a Fatty-Amine derivative of the hydrocarbon chain, was investigated and used in the production of asphalt to examine the effect. The overall influence of the admixture and temperature was examined. Seven (7) Laboratory specimens with different additive contents of 0%, 0.25%, 0.5%, 0.75%, 1.0%, 1.25% and 1.5% were produced and compacted at different compaction temperatures of 100°C, 115°C, 130°C, 145°C and 160°C, to evaluate Marshall Stability parameters. The binder content for the control test and admix samples were all kept constant for the range of 5.0%, 5.5%, 6.0%, 6.5% and 7% by weight of total mix for all the trial mixes for proper and uniform observation and also for the determination of the optimal mix for the control and admix samples. For each specimen mix, two (2) Marshall cylindrical samples were compacted at heavy compaction level of 75 blows, which represent heavy traffic category, and the mean result obtained for accuracy. This was done for all the temperature categories. Therefore, for this research work, 350 cylindrical cubes of Marshall Samples were evaluated in the laboratory. The result shows that despite the modification on the asphalt by the Evotherm product, the admixed asphalt exhibited similar engineering properties as Hot Mix Asphalt even at lower temperature of 115°C, and could be used as a first step in the promotion of improved carbon print from Nigerian Asphalt pavements.

The direct formation of carbon-heteroatom bonds, while essential in chemical/biological processes and energy storage systems, remains technologically challenging1,2. On the other hand, conjugated microporous polymers (CMP) are a unique class of 2dimensional polymers that combine extended p-conjugation with inherent porosity3. However, these polymers are synthesized through solution-phase reactions, which preclude not only the evaluation of their conducting properties but also the fabrication of thin films for device implementation4,5. Here, we describe a simple and ultrafast method to form carbonheteroatom bonds in reduced graphene oxide (RGO) by ultrasonic chemical reaction (Figure 1). Furthermore, we also successfully confirmed that the thin film polymerization of CMP by ultrasonic spray technique (Figure 2). These functionalized graphene and CMP materials have shown promising electrochemical energy storage and catalytic properties. Because of the simplicity of the process and the controllability of structural parameters, this approach opens many opportunities in the design and fabrication of electrochemical energy storage devices, as well as other energy-related applications.

What do scholars exactly mean when they write about Shakespeare being "removed from his homeland and his native tongue"? Who is Shakespeare really native to? Finally, are we all supposed to "go native" when we read, watch, study or write about Shakespeare, whatever "Shakespeare" may represent and whatever "native" is intended to describe? It is, fortunately, impossible to "go beyond" these questions if one is concerned with "Shakespeare" as a (supra)national phenomenon and if one is willing to acknowledge cultural and historical difference where it seems to be denied. This discussion is haunted by the shadows of the recent Shakespearean past(s) and worried about the emerging spectres of the Shakespearean future(s). It stubbornly, and obviously unfashionably, laments the lack of awareness of where we stand when we watch, where we sit when we read, and where we are heading when we write or (often quite heedlessly) lecture about that infinite variety of things which, we are still taught, is best termed "Shakespeare".

This research, which was conducted for dental hygienists, intended to check out what factors have an influence on their behaviors by measuring the level of self-efficacy and consciousness on the use of radiation, knowledge and attitude on radiation safety management(RSM). The subjects were 235 of the dental hygienists and this study performed a survey 8 May to 17 June, 2011. The survey results were as follows. 1. As a result of comparing the average of the self-efficacy according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to health condition, protection facilities condition. 2. As a result of comparing the average of consciousness about radiation use according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to medical institute type, protection facilities conditions. 3. As a result of comparing the average of the behaviors for RSM according to the general characteristics, a statistically meaningful difference(p<0.05) was found according to monthly income, medical institute type, whether or not education on radiation was conducted, the number of education, education type, and protection facilities condition. 4. As a result of analyzing what factors have an influence on the behaviors for RSM by employing the points of those behaviors as a dependent variable and self-efficacy, consciousness, knowledge and attitude as an independent variable in order to investigate those factors, it turned out that the factors which had a relatively larger influence on the point of behaviors were attitude and self-efficacy by that order(p<0.05). In conclusion, we believe that a variety of programs should be offered to provide knowledge on RSM as a prerequisite for improving the level of RSM behaviors by dental hygienists.


Ingestion of foreign bodies that lodge in the upper gastrointestinal (GI) tract is a common clinical situation. A 34 year-old male who swallowed an unusual huge spring in a bet without any symptoms. There were no available endoscopic overtubes or devices for this kind of huge foreign object to protect the esophageal mucosa from laceration during the retrieval procedure. Fortunately, it was removed by endoscopy without severe complications. We present the case to arouse further concern about such as huge foreign bodies, how to be extracted more safely and less invasive.

Rhesus monkey rhadinovirus (RRV) exhibits high levels of sequence homology to human gammaherpesvi- ruses, such as Kaposi's sarcoma-associated herpesvirus, and grows to high titers in cell cultures, making it a good model system for studying gammaherpesvirus capsid structure and assembly. We have purified RRV A, B, and C capsids, thus for the first time allowing direct structure comparisons by electron cryomicroscopy and three-dimensional reconstruction. The results show that the shells of these capsids are identical and are each composed of 12 pentons, 150 hexons, and 320 triplexes. Structural differences were apparent inside the shells and through the penton channels. The A capsid is empty, and its penton channels are open. The B capsid contains a scaffolding core, and its penton channels are closed. The C capsid contains a DNA genome, which is closely packaged into regularly spaced density shells (25 A˚ apart), and its penton channels The different statuses of the penton channels suggest a functional role of the channels during capsid maturation, the overall structural similarities of RRV capsids to alphaherpesvirus capsids suggest a common assembly and maturation pathway. The RRV A capsid reconstruction at a 15-A˚ resolution, the best achieved for gammaherpesvirus particles, reveals overall structural similarities to alpha- and betaherpesvirus capsids. of capsid, including densities attributed to the Ta triplex and the capsomer-interacting protein (SCIP or ORF65), prominent from their structural counter- parts in alphaherpesviruses. structural disparity that SCIP and the triplex, together with tegument and envelope proteins, confer structural and potentially functional specificities to alpha-, beta-, and gammaherpesviruses. micrographs were used to determine the initial orientation parameters of the corre- sponding particles from the close-to-focus micrographs, which were subsequently refined. The final 3D reconstructions were generated by merging only the close- to-focus particles (defocus values ranging from 0.8 to 2.1 (cid:5) m) by using the Fourier-Bessel synthesis method (13) with correction of the contrast transfer function (57). The effective resolution was based on the criterion of the Fourier shell correlation coefficient being larger than 0.5 between two independent reconstructions from arbitrarily split data sets. 3D visualization was carried out by Iris Explorer (NAG Inc., Downers Grove, Ill.) with custom-designed modules structures of deviation


We compute conformal correlation functions with spinor, tensor, and spinor-tensor primary fields in general dimensions with Euclidean and Lorentzian metrics. The spinors are taken to be Dirac spinors, which exist for any dimensions. For this, the embedding space formalism is employed and the polarisation spinors are introduced to simplify the computations. Three-point functions are rewritten in terms of differential operators acting on scalar-scalar-tensor correlation functions. This enables us to determine conformal blocks for four-point functions with scalar and spinor fields by acting the differential operators on scalar conformal blocks, which will be useful in finding their geodesic Witten diagrams.

In this paper, the writers sum up the process and practice of the EEC Consumer Policy Iniegration. The measure of FEC consumer Protection Integration has a latent risk,that is , the criteria set by EEC may be less strict than the existing national ones. Concernin gthis problem, the writers penetrate its superficial contradiction and offer a totally new idea that EEC economic integration itself is a form of consumer policy. This idea serves as a basic premise to study consumer protection in the EEC integrated market. In the summary of the paper, the writers also sum up the experience in EEC's realizing its consumer policy integration.


We introduce in this paper an algebra of actions specially tailored to serve as basis of an action-based formalism for writing electronic contracts. The proposed algebra is based on the work on Kleene algebras but does not consider the Kleene star and introduces a new constructor for modelling concurrent actions. The algebraic structure is resource-aware and incorporates special actions called tests. In order to be in accordance with the intuition behind electronic contracts we consider new properties of the algebraic structure, in particular a conflict relation and a demanding partial order. We also study a canonical form of the actions which, among other things, helps to naturally define a notion of action negation. Our action negation is more general than just negation of atomic actions, but more restricted than the negation involving the universal relation. A standard interpretation of the algebra is given in terms of guarded rooted trees with specially defined operations on them. The algebra is proven to be complete over the standard interpretation.
