We prove the existence of a compact, finite dimensional, global attractor
for a coupled PDE system comprising a nonlinearly damped semilinear wave
equation and a nonlinear system of thermoelastic plate equations,
without any mechanical (viscous or structural) dissipation in the
plate component.
The plate dynamics is modelled following Berger's approach; we investigate
both cases when rotational inertia is included into the model and when it
is not.
A major part in the proof is played by an estimate--known as
stabilizability estimate--which shows that the difference of any
two trajectories can be exponentially stabilized to zero, modulo a
compact perturbation.
In particular, this inequality yields bounds for the attractor's fractal
dimension which are independent of two key parameters, namely $\gamma$
and $\kappa$, the former related to the presence of rotational inertia
in the plate model and the latter to the coupling terms.
Finally, we show the upper semi-continuity of the attractor with
respect to these parameters.


This report provides an up-dated assessment of the situation in Ukraine's financial sector (banks as well as non-banks) and defines a policy agenda for the next stages of reform. The report is addressed to those in authority in Ukraine who have influence over the future development of the sector. The report updates a 1995 report prepared by the Bank that has served as the framework for much of the Bank's involvement with the sector in the intervening six years, and has also been a significant influence on the government's own reform efforts in the sector. This report looks in detail at a sub-set of the necessary policy reforms. Some other matters such as deregulation and the detailed proposals regarding banking supervision have been the subject of other detailed Bank and International Monetary Fund (IMF) reports and so are not considered here. The remainder of this Policy Report is organized as follows. Section two has two main purposes. The first is to identify the main elements in the recent performance of the real economy that have complicated the task of developing a stronger financial sector. The second is to identify the various ways in which the financial sector is failing to make as large a contribution as it could to the economy's recovery and future growth. Annexes one and two provide further elaboration. Section three sets out the basic framework for designing the reform agenda for the banking component of the sector. Section four provides a forward looking perspective of what might realistically be expected by way of new financing for the economy through the period to 2005 in the event that a sustained reform effort is now adopted. Section five looks in more depth at the banking sector and analyses the size and nature of the reforms in individual classes of banks especially the larger ones that will be needed to realize the stronger future performance for the sector as set out in section four. Section six provides a similar in-depth analysis of the situation of the nonbank financial institutions, including some whose activities interact very directly with the capital market institutions. Section seven defines the integrated reform strategy for the sector which emerges from the analysis in the report and related reports by others.

An ultrasonic visual sensor using a neural network is proposed and improved by reducing both the size of the neural network and the number of teaching samples. A 3-D image calculated by acoustic imaging is transformed into position and rotation invariant values, and then reorganized by a multilayered neural network. Many categories of metal or glass objects can easily be classified with this system, even when they are placed at unknown positions or rotation angles.<<ETX>>


This chapter introduces the reception of Thomas Aquinas by a number of theologians of the early twentieth century. While each of these students of Aquinas could be labelled as 'neo-scholastic' theologians, the authors represented here also embody a wide range of approaches (historical, pastoral) to the theological teaching of Thomas Aquinas. This chapter introduces each of these neo-scholastic Thomist theologians in relation to their reception of Aquinas on key topics related to the principal ecclesial crises of the period, especially the nature of theology, Christian faith, and dogma. Furthermore, the reception of Aquinas' doctrine of grace and pneumatology as a source for the moral and spiritual renewal of the Church by key neo-scholastic authors is also presented.


Tracheostomy management has been the focus of a number of reviews in the UK over the last decade; however, paediatric patients have thus far been excluded from the analysis.1 ,2 Currently, there are no formally accepted national standards in the UK for paediatric tracheostomy management. Paediatric tracheostomies are associated with risks and complications in the order of two to three times higher than morbidity and mortality rates reported in adults. The mortality rate for a complication directly related to a paediatric tracheostomy is 0.7%.3 The majority of reported adverse incidents do not occur in the immediate postoperative period; late complications over a week from insertion are four times more common.4 Our aim was formalising standards of optimal paediatric tracheostomy management to minimise future morbidity.

Assessments of paediatric tracheostomy care were collected from 40 consecutive patients at a tertiary specialist paediatric institution in 2007. An initial multidisciplinary root cause analysis of morbidity associated with paediatric tracheostomy was carried out by the senior authors. Main areas of concern relating to tracheostomy care were identified, and from these, proposed minimum standards of best practice were developed. The recommendations were neatly encompassed in the mnemonic 'TRACHE' promoted as the recommended paediatric tracheostomy 'care bundle' (figure 1).

This 'TRACHE' care bundle was communicated widely within our hospital using the following means:

Further assessments were performed at regular intervals by the tracheostomy nurse specialist and senior authors on ward nursing staff caring for …


Abstract : The possibility of using queueing networks to study the performance of multiprogrammed computer systems that use memory hierarchies was investigated. It was found that these kinds of models are adequate provided the success function of the memory hierarchy is known. A stochastic algorithm to obtain the success function of the hierarchy was developed. The results obtained, whenever this model is used in conjunction with the queueing network, were extensively compared with conventional simulation techniques, and the accuracy found to be within five percent. The problem of scheduling the Central Processor was considered, and empirical algorithms to determine policies that set upper and lower bounds on the success function of the hierarchy were proposed. Mathematical methods were employed to analyze various system configurations, that include several input-output channels and processors. (Author)

Objectives To investigate the association between birth weight and blood pressure (BP) and to determine the effect of body size change from birth to adulthood on BP. Design A cross-sectional design to collect retrospective data. Participants 1253 female nurses aged 35–65 years in Hong Kong. Main outcome measures Birth weight, height, weight, BP, waist circumference, demographics and lifestyle factors were collected by a self-administered questionnaire through mail survey. These self-reported variables have been validated in a pilot study. The conditional relative weight (CRW), which was calculated as a residual of current weight regressed on birth weight, was used to express higher or lower relative weight gain from birth to adulthood. Results No significant linear association between overall range of birth weight and BP was found. The curve estimation showed a significant quadratic curvilinear association ('J' shape). In the piecewise-linear analysis, a significant inverse association between birth weight z-scores and BP was observed in the birth weight ≤3.1 kg group (systolic BP (SBP): coefficient B=−1.73, 95% CI −3.17 to −0.30; diastolic BP (DBP): B=−1.12, 95% CI −2.19 to −0.06). A positive but non-significant association occurred in the birth weight >3.1 kg group. Participants who belonged to the lowest 10% birth weight category but at the current top 10% BMI group had higher BP than participants in other BMI groups. The CRW z-score was positively associated with BP (coefficient B: 4.18 for SBP and 2.87 for DBP). Conclusions Unlike most previous studies, we found a 'J' shape association rather than a linear association between birth weight and BP. Women with large percentile crossing of body size from birth to adulthood were more likely to have elevated BP. A higher weight gain from birth to adulthood than expected led to higher BP.


India has a long history of cyclonic and flood damage. Occurrence of severe cyclones is be coming more frequent. It is known that these recurrent problems should be dealt at their root and not by merely treating after-effects and consequences why then there is failure of Govt. In planning to meet periodically recurrent devastating cyclonic force. Tbe paper analyses this situation and brings out the need for giving due weightage to social environment in project formulation.


The secondary optics design is a critical issue for the output efficiency and light distribution pattern of the LED street light.A good roadway illumination requires the LED streetlight to have a rectangular light distribution pattern just cover the roadway and without any light pollution out of the road.The adoption of the unsymmetrical freeform optics with a rectangular light distribution on X and Y is a necessary which makes the LED streetlight become very simple and high efficiency.The whole LED streetlight can be made up if only mounts these LED modules on the PCB plate.The mechanism,thermal management,and the power control electronics of the LED streetlight becomes very simple.In this paper,the optical design of the LED streetlight and the calculation methodology of a freeform optics for the streetlight was put forward.

Pi (π) is used to represent the most known mathematical constant. By definition, π is the ratio of the circumference of a circle to its diameter. In other words, π is equal to the circumference divided by the diameter (π = c / d). Conversely, the circumference is equal to π times the diameter (c = π . d). No matter how big or small a circle is, pi will always be the same number. The first calculation of π was made by Archimedes of Syracuse (287-212 BC) who approached the area of a circle using the Pythagorean Theorem to find the areas of two regular polygons: the polygon inscribed within the circle and the polygon within which circle was circumscribed. Since the real area of the circle is between the areas of the inscribed and circumscribed polygons, the polygon areas gave the upper and lower limits to the area of the circle. Archimedes knew he had not found the exact value of π, but only an approximation within these limits. In this way, Archimedes showed that π is between 3 1/7 (223/71) and 3 10/71 (22/7). This research demonstrates that the value of π is 3.15 and can be represented by a fraction of integers, a/b, being therefore a Rational Number. It also demonstrates by means of an exercise that π = 3.15 is exact in 100% in the mathematical question.


The article is devoted to one of the topical interdisciplinary problems, since it equally applies to dentistry, dermatology, rehabilitation and, in general, to all practical medicine. Emphasis is placed on the pain syndrome and the psycho-emotional status of dental patients who, against the background of comorbid pathology (diabetes) or in the postoperative period, develop structural changes in the underlying tissues and organ systems. Diagnostic methods for verification of keloid scars are constantly improved. Advancement of modern technologies, including drug-free ones, are crucial for rehabilitation of patients with cicatricial pathology. Modern methods of verification of keloid scars in dental patients with diabetes, taking into account the evidence analysis of indicators of keloid formation, are presented. These methods made it possible to increase the clinical effectiveness of physiotherapy.

In this paper multi-hull small-sized motor yachts with rounded bilge hulls were examined as alternative options for enough high speed: catamarans without and with under-water foils, as well as outriggered boats without and with foils. Besides, a twin-hull motor yacht with decreased water-plane area was examined too. Restriction of speed, as a result of avoiding hard chine, was examined; necessary power and seakeeping levels of the examined yachts were estimated too. It has shown that the examined yachts are compatible (from the energy point of view) with today's dominant planing monohulls for defi ned ranges of speed; the examined multi-hulls are better from the seakeeping point of view than the comparable monohulls.


We tackle the resolution of a probabilistically-constrained version of the DC Optimal Power Flow problem with uncertain demand. The chance constraint requires that the probability of violating any of the power system's constraints be lower than some parameter ą 0. We use Sample Average Approximation to produce a data-driven deterministic reformulation of the problem, which takes the form of a large-scale mixed-integer program cursed with Big-Ms. We then introduce an exact resolution method for the MIP that combines the addition of a set of valid inequalities to tighten the linear relaxation bound with coefficient strengthening and constraint screening algorithms to improve its Big-Ms and considerably reduce its size. The proposed valid inequalities are based on the notion of k-envelopes, can be computed offline using polynomial-time algorithms, and added to the MIP program all at once. Furthermore, they are equally useful to boost the strengthening of the Big-Ms and the screening rate of superfluous constraints. In a series of numerical experiments which involve five power systems of different size, we show the efficiency of the proposed methodology and compare it with some of the best-performing convex inner approximations currently available in the literature.


The energy band structure of mechanically free and compressed RbKSO4 single crystals is investigated. It is established that the top of the valence band is located at the D point of the Brillouin zone [k = (0.5,0.5,0)], the bottom of the conduction band lies at the point, and the minimum direct band gapEg is equal to 5.80 eV. The bottom of the conduction band is predominantly formed by the K s, Li p, Rb s, and Rb p states hybridized with the S p and O p antibonding states. The pressure coefficients of the energy position of the valence and conduction band states and the band gapEg are determined.


This study investigated physical self-perceptions (PSPP and PIP) and the relationship between physical self-perceptions and body composition measures (BMI, WHR, percentage body fat) in fitness instructors (n = 36), regular exercisers (n = 29) and non-exercisers (n = 35). Gender differences were apparent in the physical self-perceptions, males scoring higher on the attractive body, sports competence and physical self-worth sub-scales of the PSPP. Fitness instructors rated their bodily attractiveness, physical condition and physical strength significantly higher and perceived them as more important than the regular and non -exercisers. Also, fitness instructors and regular exercisers had higher levels of physical self-worth and sports competence and perceived sports competence as more important than the non-exercisers. Relationships between physical self-perceptions and body composition were found. For females higher fat percentage or BMI values were negatively associated with most of the sub-domains of the PSPP. It was concluded that participation in regular exercise is associated with more positive physical self- perceptions that might contribute to a 'life-time' commitment to exercise participation. Secondly, more longitudinal research is required to investigate the relationship between physical self-perceptions and changes in body composition. Finally, it was suggested that exercise programs should promote competence and should be conducted in a relatively 'body neutral' environment. Such an approach would propagate a more intrinsically motivated orientation to exercise participation and might have a more pronounced effect on physical self-perceptions and global physical self-esteem


First Peter, which contains one of the largest concentrations of citations and allusions to the Old Testament of any New Testament book other than Revelation, cites Psalm 34 twice, with the longest sustained reference in 1 Peter (3:10–12) from this song. This essay examines how the citation and allusion to this psalm serves to further the exhortation of Peter's epistle. In order to answer these questions, the author analyzes the citation of Ps 34:13–17 in 1 Pet 3:10–12. After a brief survey of the New Testament context of the quotation, he then considers the Old Testament context to see how it may inform the function of the citation and allusions to the psalm in 1 Peter. The examination of Peter's use of Psalm 34 suggests that he did so because it has the same theme as his letter, namely, suffering and deliverance. The citation suggests that Peter's exiled and righteous readers, like the exiled and righteous psalmist, may suffer affliction and tribulation but they can also rejoice that they will also experience the "good life" and taste the Lord's kindness in spite of suffering.


the term khushdashtya, which really means "Mamluk comrades who were members of the same Mamluk household." In any event, the passage is problematic; it implies that Aybak was a member of the Bahrlya. However, a comparison with the parallel passages in Kanz al-durar (7.25-26, 31) shows tha t the intention is not to the Aybak's khushdashtya, bu t ra ther to those of the murdered BahrT leader Aqtay. The confusion would seem to stem from Ibn al-Dawadari's desire to be terse in Tijan al-durar. This discrepancy certainly deserves mention in a note. Exception can also be taken to the translation of some other technical terms: for instance, "Leute" is insufficient for nas (p. 225) when the Mamluks or members of the military society are intended (but cf. p . 227, where it is correctly translated); khassakiya is bet ter glossed as "personal entourage of the sultan" rather than "Leibgarde" (pp. 223, 225); yalji [sic: should be yilji < ilchi] is correctly translated as "Gesandter" (p. 198), but in the index (p. 296) the incorrect meaning of "Gesandtschaft" is also given. These, however, are minor comments, and Graf has done an important service by making this material readily accessible to scholars.


Bonding is an abstract material and has a high level of difficulty. Most students have difficulty in determining the Lewis structure and valence electrons so that facilities are needed that support the learning process and are in accordance with the curriculum that emphasizes guided inquiry learning. The implementation of a learning can be supported by the existence of relevant learning facilities. One of the learning tools that can be used is teaching materials in the form of modules. Research and development aims to determine the feasibility and to investigate the response of students to chemistry learning modules based guided inquiry on chemical bonding material class X. This study uses the Research and Development (RD). Based on the validation of the results obtained material experts 85.26%, media expert results obtained 92.00% with products developed thus expressed very worthy to use. After validation of the product to expert lecturers and chemistry teachers, the product was tested on a small scale to 17 students. The students' responses were obtained with a percentage of 84.14% stated in the very feasible criteria, thus the module developed in the small-scale trial was included in the criteria very suitable for use in the learning process.


This thesis is structured around contributions in the areas of domestic and mobile networks.

In the case of mobile networks, we are interested in understanding the relationship between wireless technology and contact opportunities among nodes on the move.


In this paper, we focus on how to make use of K-PSO(Particle Swarm Optimization) algorithm to improve efficiency of the ontology modularization method. As a bridge of man-machine semantic interaction, ontology has an important status of logic basis of semantic realization and the upper expression of the metadata in the frame of the semantic web. But relative to the rich ontology resources, the application of specific network based on ontology auxiliary is relatively less. In order to solve this problem, we propose the ontology modularization method based on the K-PSO algorithm to make large-scale ontology play an important role in the organization of network information. Ontology modularization method proposed in this paper converts the problem of large-scale and intractable ontology semantic extraction into the internal dynamic extraction of ontology modules, and realizes the optimization semantic clustering of ontology modules. This method can effectively solve the actual application problems of ontology in the network information system based on semantic. Through a number of experiments, it shows that the method and framework to solve the problem in this paper is feasible, versatile and expansible. Compared with the classical clustering method, this method shows a better performance, which can use the particle swarm optimization algorithm to realize module clustering.


Contemporary business is largely based on digital information. Traditional media forms lose battle in a new global surrounding. Therefore, knowing specific terminology and postulates of new conditions in the digital information market is essential. Globalization is an inevitable process overtaking all economic activities, including tourism sector intertwined with various advertising activities in order to place and sell its products and services. Digital marketing is thus more and more used. In that context, world tourism organizations and national tourist agencies play a role of communicator, trying to create desired mental image of a specific country as a tourism destination in the minds of final consumers. They use branding to make one country uniquely recognizable in the market. The aim of this paper is to present new trends in tourism destination branding process by using the means of digital marketing. The main purpose of this research was to analyse marketing activities and communication strategies of European countries, perceived as the largest tourism market, and compare them with the tourism promotion of Croatia in various markets. The results of the analysis of Croatian activities in promoting its tourism destinations imply there is still a large potential to improve implementation of digital marketing means by preparing the strategy of integrated market communication. The analysis of marketing activities of tourism developed countries shows trends in digital marketing that can serve as a model for development of Croatian tourism brand in global digital surrounding.


Three new series of quinazolinone derivatives containing amide, urea, and sulfonamide were synthesized through multistep synthesis. The required intermediates 4-[(4′-oxo-2,3,3′,4′,5,6-hexahydro-1′H-spiro[pyran-4,2′-quinazolin]-1′-yl)methyl]benzoic acid 4 and 1′-(3-aminobenzyl)-2,3,5,6-tetrahydro-1′H-spiro[pyran-4,2′-quinazolin]-4′(3′H)-one 8 were prepared by hydrolysis of ester and reduction of nitro intermediates. Three different series of compounds were synthesized from these two scaffolds. The key scaffolds 4 and 8 were successfully converted to target molecules via amides 5a–k, urea 9a–f, and substituted sulfonamides 10a–e. The chemical structures of newly synthesized compounds were characterized by spectral analysis. The structure of 5d was confirmed by X-ray crystallography study. These newly synthesized compounds were screened for antibacterial studies against Staphylococcus epidermidis, Salmonella typhi, Proteus mirabilis, and Shigella sonnei and for the antifungal activity against Aspergillus niger and Candida albicans. Among all the compounds, 9b–d showed excellent activities against S. typhi. Compound 9a showed moderate activity against all fungi stains, and 5I showed moderate activity against P. mirabilis, while the other derivatives showed fairly good activities.


Immune Reconstitution Infl ammatory Synndrome (IRIS) A paradoxical clinical worsening of a known condition or the appearance of a new condition after initiating antiretroviral therapy (ART) therapy in HIV-infected patients resulting from restored immunity to specifi c infectious or non infectious agents is defi ned as immune reconstitution infl ammatory syndrome (IRIS).1 This entity is also known by other names such as immune restoration disease (IRD), immune reconstitution syndrome (IRS), and paradoxical reactions. Based on observation that the clinical deterioration occurs during immune recovery and the fact that the host infl ammatory response plays an important role in this syndrome, the term (IRIS) has been proposed2 and has become the most widely used and accepted term to describe the clinical entity. In a large retrospective analysis by French et al, 33/132 (25%) of patients exhibited one or more disease episodes after initiation of ART.3 Other cohort analyses by Ratnam and associates, reported that 17–23% of patients initiating ART will develop the syndrome.4 The spectrum of etiological factors for this entity is very broad. There is also a wide variation in the clinical presentation of this entity. These facts make the diagnosis of this condition diffi cult. Currently no test is available to establish the diagnosis of IRIS. The diagnosis is mostly clinical with supportive laboratory evidence. The diagnosis requires high index of suspicion and identifi cation of the risk factors.

Two methods of seismic risk assessment are compared . The first one is based on historical data. It con siders statistics of earthquakes of epicentral intensities I0 = V to IX and statistics of areas affected by inte nsities lower than or equal to I (I<=I 0). The risk is estimated in terms of annual probabi lity of occurrence of given damage degrees. Typical outputs are that, in average for m asonry buildings, probability of a degree 2 damage is around 10 ; 10 for a degree 3. The second method is based on conv olution of seismic hazard data and masonry building fragility curves. Seismic hazard is descri bed in the form of 3 different maps of the metropol itan France. These maps are outputs of probabilistic seismic haz ard assessments of France and provide PGA values fo r a 475 year return period (PGA values for other return per iods are extrapolated on the basis of classical rel tionship between PGA and return periods). Fragility of mason ries is described in the form of a classical log no rmal distribution of the probability of exceedance of a given damage versus the PGA (median value 'a' and variability 'β'). A sensitivity study is carried out on the media n value corresponding to damage degrees 2 and 3. For realistic values of 'a' and ' β', one of the maps leads to an tremendous overestim ate of the risk, as compared to the historically observed risk, another one lead s to an underestimate while the third one is in the middle. This approach could be used for reducing uncertainties i n probabilistic seismic hazard assessment in low-mo derate areas where sufficient historical data are availabl e.


Nowadays,the output of polymer flooding in Daqing oilfield has surpassed 100 million tons,and it has created tremendous economic benefits.To ascertain the rational time in polymer injection become a problem concerned by all of the science and technology personnel,thus,the enhancing recovery percent function of polymer flooding will be fully exerted.According to the requirement of oilfield development,we started to process physical simulation experiments in the laboratory on man-made 1-D rectangle core and 2-D plane core,on condition that the water cut is different.The result shows that if we inject the same polymer solution in weight,the flooding effect will be better when the water cut is 75% than when it is 95%,whatever the experiments were on the rectangle core or the place homogeneous core.


The mechanical analysis is carried out for the preliminary design of the pipeline crossing diagonal cable type structure in Mulong River by the finite-element method.The results indicate that the cable with some pre-strain can improve the strength and the stiffness of the structure while it is installed,but if the prestrain is too large the strength and the stiffness will be declined,so there is an optimum value of pre-strain for the structure,to be influenced by the form of structure and the loads on structure;under the work loads or the water filling loads,the strength of the structure just meets the requirements.Under the ultimate loads,the strength of the structure does not meet the requirements.There are three places where the maximum stress is reached in the structure the left tower top connected with cable,the right tower top connected with cable and the upper limb of the intermediate pipe bridge.


Southwark Council has pledged to build new premises for a community church so it can remain in the heart of the Elephant and Castle area, which is set to undergo a £1.5bn transformation over the next fifteen years.


How to resist geometric attacks is currently the focus and difficulty in video watermarking fields.This paper presents a video dual watermarking method which could effectively resist geometric attacks.The method mines a geometric deformation invariant,namely the low-dimensional manifold of video,and theoretically derives and experimentally demonstrates geometric invariance.First of all,the method generates zero-watermark or dynamic semantics watermark online according to low-dimensional manifolds of different video shots.In order to balance the robustness and transparency,the method embeds watermark in the IF DCT coefficients of AVS predicted residuals with large energy.This paper studies deeply the three-dimensional space-time characteristics of video,effectively quantifies and characterizes video motion information by low-dimensional manifold of video,establishes the human dynamic masking model including movement features,brightness features and texture features,so as to adaptively control watermark embedding strength.Experiments and analysis show that this method can effectively resist center cutting,irregular cutting,row cutting,rotation,scaling,translation and other high intensity geometric attacks and combined attacks,such as rotation and corner cutting,center cutting and rotation,etc.It also has strong robustness to the conventional video signal processing and various video attacks.


▼ Recent fi ndings showing signi fi cant correlations between phospholipase A2 (PLA2) activity and structural changes in schizo-phrenic brains contribute to the membrane hypothesis of schizophrenia, which was hampered because a clean functional link between elevated PLA2 activity and brain structure was missing (Neuroimage, 2010; 52: 1314 – 1327). We measured membrane fl uidity parameters and found that brain membranes isolated from the prefrontal cortex of schizophrenic patients showed signi fi cantly increased fl exibility of fatty acid chains. Our fi ndings support a possible link between elevated PLA2 activity in cortical areas of schizophrenic patients and subsequent alterations of the biophysical parameters of neuronal membranes leading to structural changes in these areas.


In this paper, a coupled MM5–CMAQ modeling system was employed to investigate the PM10 pollution issue in Beijing, China, with a focus on assessing the effects of different restriction policies implemented during and after the 2008 Olympic Games. The simulations under designed scenarios were implemented over a 2-level nested grid domain for comparing the difference of PM10 concentrations under restriction and no-restrictions situations. The restriction measures include alternate-day vehicle driving, construction activities, trans-boundary emissions from neighboring provinces, and vehicle restrictions during the post-Olympic period. Meteorological contributions to the air quality improvement were also examined. The results show that significant improvement of air quality in Beijing during the 2008 Games was attributed largely to these restriction measures, although favorable weather conditions play an important role. Also, during the post-Olympic period, daily vehicle restrictions implemented temporarily under extreme weather conditions played a crucial role in alleviating Beijing's air pollution. Beijing not only needs to take continuing efforts to addresses its own PM10 problem, but also has a clear self-interest in demanding better environmental performance from neighboring provinces. It is suggested that Beijing would work collectively with neighboring provinces to develop a long-term multi-region initiative and strategy aimed at emission reduction for providing the citizens in this region a healthy and clean air in the long run.


Evaluation functions are very crucial in educational comprehensive evaluation. This study summarizes some classical evaluation functions and shows their usage in Pedagogic evaluation applications. The study also presents and illustrates some hybrid evaluation function with some types of preferences of decision makers involved. Some illustrations with examples show that different types of preferences can embody both educators' teaching experience and their optimism/pessimism decision attitudes. Therefore, the analyses in this study can help first line teachers select suitable, flexible and reasonable models for their practical educational comprehensive evaluations.

The coherence of light has been proposed as a quantum-mechanical control to enhance light-harvesting efficiency. In particular, optical coherence can be manipulated by changing either the polarization state or spectral phase of the illuminating light. Here, we show that, in weak light, controlling the light-harvesting efficiency using any form of optical coherence is impossible in all molecular light-harvesting systems and, more broadly, those composed of weakly interacting sub-units which lack fixed orientational order and operate on longer-than-ultrafast timescales. Under those conditions, optical coherence does not affect light-harvesting efficiency, meaning that it cannot be used as a form of control. In particular, control through the polarization state is lost in disordered samples or when the molecules reorient on the timescales of the light-harvesting, and control through the spectral phase is lost when the efficiency is time-averaged for longer than the coherence time of the light. In practice, efficiency is always averaged over long times, meaning that coherent optical control is only possible through polarisation in systems with orientational order.


Abstract Microfossils in core samples from two wells in the Minas Field of Central Sumatra were analyzed to assist in the development of a reservoir model. Using microfaunal distributions in the modern Mahakam Delta of Kalimantan as a guide, the depositional environments of the Early Miocene (Burdingalian) Bekasap Formation (Sihaps Group) are interpreted as ranging from fluvial deltaic plain to distal delta front or possibly prodelta. Marine: nonmarine ratios of playnomorphs yield similar trends and validate using the Mahakam microfauna as a modern analog here. Biotic distributions appear to be controlled primarily by the deltaic salinity and pH gradients. The association of large coastal foraminifera with minute deeper water forms implies shoreward transport of the latter and supports the concept of a tidally dominated Bekasap delta. Future microfossil investigations may play an important role in characterizing reservoir heterogeneity as we seek to enhance our understanding of reservoir producibility.


Extensive experimental studies of the ionic sound waves predicted by Tonks and Langmuir are discussed. Selfexcited oscillations have been observed both in magnetically supported plasma columns and in spherical discharge tubes. The fundamental frequency and the overtones of each system agree with those predicted by the ionicsound-wave formula in terms of the electron temperature, the ion mass, and the dimensions of the system. A simple equation is used to predict when damping by the neutral gas prevents a given mode of plasma oscillation from being observed. The thermal electron pressure, required for the existence of an ionic sound wave, has been measured mechanically. Resonance effects have been observed between the ionic-sound and the ion cyclotron frequency in the magnetically supported plasma column. Practical applications of ionic sound waves are as follows: The electron temperature of a plasma was found by measuring the frequency of a standing ion-wave mode. The neutral gas density was estimated by observing the gas damping of various standing ion-wave modes. (auth)


Abstract Purpose This study investigated the predictive role of psychological flexibility on long-term mTBI outcomes. Method Adults with mTBI (N = 147) completed a context specific measure of psychological flexibility, (AAQ-ABI), psychological distress, and mTBI outcomes at less than three months post injury (M = 6.02 weeks after injury) and 6 months later (N = 102). Structural equation modelling examined the mediating effects of psychological flexibility on psychological distress and mTBI outcomes at six months. The direct effect of psychological flexibility at less than three months on mTBI outcomes at six months was entered into the model, plus pre-injury and injury risk factors. Results The theoretically derived model had good overall fit (χ2 = 1.42; p = 0.09; NFI = 0.95; TLI = 0.95; CFI = 0.98 and RMSEA = 0.06). Psychological flexibility at less than 3 months was directly significantly related to psychological distress and post-concussion symptoms at six months. Psychological flexibility at 6 months significantly mediated the relationship between psychological distress and functional disability but not post-concussion symptoms at six months post injury. Conclusion The exploratory findings suggest that a context specific measure of psychological flexibility assessed acutely and in the chronic phase of recovery may predict longer-term mTBI outcomes. Implications for Rehabilitation Persistent post-concussion symptoms (PPCS) after mild traumatic brain injury (mTBI) can have a significant impact on wellbeing, functional status, and quality of life. In this study, psychological flexibility early in recovery, was associated with higher levels of psychological distress and more severe post-concussion symptoms six months later. Psychological flexibility at six months post-injury also mediated the relationship between psychological distress and functional disability. A context specific measure of psychological flexibility may predict poorer long-term outcomes following mTBI.

Indiana had an unusually sizeable Quaker population by 1850 that formed the state's fifth largest denomination and comprised the fourth largest number of Quakers in the United States. Quaker churches were concentrated in east-central Indiana. Most of the Quakers came from the South, particularly North Carolina. Southern Quakers had freed their slaves by 1800 and were actively opposed to the "peculiar institution," and many free blacks lived near them. When economic and political conditions in North Carolina became intolerable for the Quakers and blacks, many of them moved to Indiana together. Although some blacks migrated separately and settled different areas, many chose to locate close to the Quakers due to their antislavery and humanitarian philosophy. As a result, there was a close association in Indiana among natives of North Carolina, Quakers and blacks by 1850.


Polybenzoxazoles such as poly(2,6-benzoxazole)(2,6-PBO), poly(2,6-benzothiazole)(2,6-PBT) and poly(2,5(6)-benzimidazole) are semi-flexible, high temperature, and high modulus polymers which have been of wide interest as the matrix components of molecular composites. These polymers and their rigid-rod relatives polybenzobisazoles(PBZT, PBO, etc) also exhibit interesting electroactive and photoactive properties. As previously shown for rigid-rod polybenzobisazoles, we have found that the semi-flexible polybenzoazoles are soluble in Lewis acid (e.g. GaCl{sub 3}, AlCl{sub 3})/nitromethane solvent systems from which films and fibers could be processed. Remarkably, 2,6-PBO films prepared by complexation mediated processing from Lewis acid/nitromethane solutions of the polymer exhibit the extended chain (trans) conformation as evidenced by optical absorption and photoluminescence spectroscopies. In contrast, 2,6-PBO films prepared from formic acid/methanesulfonic acid(FA/MSA) solvent am predominantly of cis-conformation. The origin of this extended chain conformation preference of 2,6-PBO films prepared from Lewis acid/nitromethane solutions lies in the stereochemical control exerted by Lewis(MX{sub 3}) coordination to the imine nitrogens of 2,6-PBO resulting in an all-trans conformation after film processing and decomplexation. Since the trans- and cis-(2,6-PBO) have dramatically different solid state properties such as optical absorption and luminescence, our results demonstrate how a high degree of control of solid state structure and properties can be achieved by novel polymer more » processing. « less


Abstract This paper aims to provide some insights into the way that the recent referendum held on June 23rd about the Brexit could affect the UK's perspective to proceed to a new round of QE. Moreover, the effects of the latter on the Eurozone are under scrutiny. Transmission channels of the shock that the Brexit has brought about on the EU and the Eurozone, as well as possible scenarios about the future relationship between the UK and the EU are presented. To the best of our knowledge, this is the first academic piece of work that makes a direct link between the consequences of the Brexit on decisions about proceeding in further QE actions or not in the UK and at the same time studies how this could result in affecting the Eurozone's economy and its decision-making about adopting further unconventional policies.


Abstract Becker in 1925 and Mott and Nabarro in 1948 gave different expressions for the stress dependence of activation energy for shear in the limit when the stress approaches that at which plastic deformation can occur without thermal activation. We show that, when allowance is made for the inevitable elastic nonlinearity in the activated state, Becker's model leads to the same dependence as that of Mott and Nabarro. This limiting expression is likely to be valid in many, but not all, processes of thermally activated plastic deformation. Following Clough and Simmons, we explore definitions of activation volumes under a general stress that are tensors and represent the volume integral of the strain which occurs during the process of activation. We then consider the influence of the sharpness of the dependence of the strain rate on the applied stress. Activation of plastic deformation at one site sheds loads on to other sites which may then activate athermally, producing a multiplication factor which is itself stress dependent and may diverge before the applied stress reaches that at which activation occurs without thermal assistance.

e15174 Background: Evaluation of novel therapies for patients with CRPC has been limited by the lack of validated quantitative measures of bone tumor burden. Tools including visual assessment for determining progression based on lesion count and semi quantitative measures including the Bone Scan Index for predicting survival have been proposed. To date, a validated quantitative measure that can be used to assess either progression or response has not been available. We have developed a computer-aided (CAD) system for measurement of bone scan tumor burden including lesion count (LC), mean intensity (MI) and total area (TA). This study is to assess the range of normal variation and potential clinically meaningful cut points for changes in bone scan tumor burden.

METHODS
From an anonymized image data set, 20 CRPC patients were selected with a pair of bone scans acquired 6 to 24 weeks apart. All patients had failed at least 2nd line drug therapy; 10 were on no therapy, 10 received drug therapy between the two scans. Scans were acquired at 12 sites using a standard of care protocol including 20-25 mCi of Tc MDP, injected 2-4 hours before whole body scintigraphy. An automated CAD system was run for each patient on bone scans. Degenerative joint disease was removed manually by one of two board certified Nuclear Medicine Physicians. A two-sample Wilcoxon rank sum (Mann-Whitney) test was used to test for differences between the two groups in the ratio of LC (visit 2 / visit 1), change in MI and % change in tumor TA.

RESULTS
Table shows the median (IQR) for ratio of LC, change in MI and % change in TA. Differences between groups were significant for all measures.

CONCLUSIONS
This preliminary data suggests total bone scan tumor area may be useful as an early surrogate outcome for CRPC patients with 30% change from baseline as a potential cut point to distinguish responders from non-responders. This work lays a foundation for validation of these measures against other clinically relevant outcome measures in a larger cohort. [Table: see text].


A new polynomial model K*TDG is proposed to solve the decomposition and search problems of complex data flow,wherein the edge weight K represents its closeness to system parameters.The concepts of K*TDG,compact K*TDG,loose K*TDG etc.are defined and the fundamental addition and multiplication operations of K*TDG are discussed.Then a new decomposition and search algorithm for complex data flow is given.In order to decrease the algorithms complexity,a grouping strategy based on the degree of polynomials of complex components is proposed.Experimental results indicate that the proposed algorithm and strategy in this paper can reduce the searching space of components by an average of 49 percent.

In this paper we obtain equations for large-scale fluctuations of a mean field (the field of magnetization and quadrupole moments) in a magnetic system realized by a square (cubic) lattice of atoms with spin s ⩾ 1 at each site. We use the generalized Heisenberg Hamiltonian with a biquadratic exchange as a quantum model. A quantum thermodynamical averaging gives classical effective models, which are interpreted as Hamiltonian systems on coadjoint orbits of the Lie group SU(3).


The invention provides a method of building label exchange paths based on resources pre-reserving protocol control, including: setting preset time for entry nodes which need to build label exchange paths; in the preset time, for an entry node which does not receive the pre-reserving information, using the resources pre-reserving protocol to cancel all the states corresponding to the entry node and related to label exchange paths; as the network failure can not be removed in time, it does not need artificial interference and can automatically cancel all the states related to the label exchange paths by the resources pre-reserving protocol according to the preset time, and avoids the waste of network resources, and can maximumly endure temporary network failure, thus realizing the purpose of saving network resources.


A new method of forming TiO2 gate insulators is proposed. It was found that ultrathin TiN deposition on ultrathin SiO2 and low-temperature thermal oxidation resulted in smaller TiO2 grains surrounded by amorphous boundaries. The gate leakage current was effectively reduced by applying ultrathin TiO2/SiO2 stacked insulators to metal-oxide-semiconductor (MOS) capacitors and Damascene gate metal-oxide-semiconductor-field-effect-transistors (MOSFETs) with good characteristics were successfully fabricated.

Additive manufacturing (AM) enables the production of complex and customised components with minimal waste. However, to achieve the desired geometry and quality, a lot of process optimisation is needed (often by experimental trial and error). Especially, in the case of AM with concrete materials, the time‐dependent behaviour of the fresh concrete is a large challenge to achieve process stability. Simulations taking into account the time‐dependent material are able to predict the printing result. Since these simulations are very time consuming, a proper orthogonal decomposition (POD)‐based reduced order model for AM is presented. Based on snapshots along the build‐up process, a surrogate model is constructed that is able to predict the printing result with respect to the underlying process and materials. Inspired by the POD approximation, a novel surrogate modelling approach using the initial waypoints of the printing trajectory as input is investigated. In this case, it is possible to analyse the manufacturing process for arbitrary geometries. The proposed method is demonstrated for the use case of additive manufacturing in construction.


We study a model with Majorana neutrino masses generated through doubly charged scalars at two-loop level. We give explicit relationships between the neutrino masses and the same sign dilepton decays of the doubly charged scalars. In particular, we demonstrate that in the tribimaximal limit of the neutrino mixings, the absolute neutrino masses and Majorana phases can be extracted through the measurements of the dilepton modes at colliders.


Quantum Zeno effect is conventionally interpreted by the assumption of the wave-packet collapse, in which does not involve the duration of measurement. However, we predict duration τm of each measurement will appear in quantum Zeno effect by a dynamical approach. Moreover, there exists a model-free critical measurement time, which quantum Zeno effect does not occur when τm takes some special values. In order to give these predictions, we first present a description of quantum Zeno effect in the Heisenberg picture, which is based on the expectation value of an observable and its fluctuation. Then we present a general proof for quantum Zeno effect in the Heisenberg picture, which is independent of the concrete systems. Finally, we calculate the average population and relative fluctuation after N successive measurements in XX model, which agrees with our prediction about the critical measurement time.

Currently, a complete system for analyzing the effect of packet loss on a viewer's perception is not available. Given the popularity of digital video and the growing interest in live video streams where channel coding errors cannot be corrected, such a system would give great insight into the problem of video corruption through transmission errors and how they are perceived by the user. In this paper we introduce such a system, where digital video can be corrupted according to established loss patterns and the effect is measured automatically. The corrupted video is then used as input for user tests. Their results are analyzed and compared with the automatically generated. Within this paper we present the complete testing system that makes use of existing software as well as introducing new modules and extensions. With the current configuration the system can test packet loss in H.264 coded video streams and produce a statistical analysis detailing the results. The system is fully modular allowing for future developments such as other types of statistical analysis, different video measurements and new video codecs.


ABSTRACT The appealing features of cryptocurrency in the digital money sector have put them into the category of investable assets. Investment professionals have begun to consider their investability and diversification benefits. It is vital for investors to understand the return-risk behaviour among investable assets to reap the benefits of diversification. This paper considers a proxy of cryptos, specifically Bitcoin, Litecoin, Ethereum, Ripple & Neo, and the Middle East stock market indices, to examine the dynamic relationship among them using the vector error correction model. This study found evidence to suggest that cryptos exhibit a co-integrated relationship while there is no evidence of significant cointegrated movements occurring between the cryptos and the market indices. The latter finding implies that cryptos are decoupled from the market indices and can serve as a diversification option for investors. The mean-variance approach confirms that cryptocurrencies fit into an optimal portfolio and involve an enhanced return-risk reward for investors.


The paper deals with some aspects of the planning and the interpretation of the IP and resistivity measurements in the San Priamo coastal plane (Sardinia, Italy). The plane presents some hydrogeological problems related to previous flowages and salt water intrusion from the sea. The geophysical results verified the good resolution of the joint elaboration of the IP and the resistivity soundings, in order to delineate some hydrogeological aspects of the San Priamo coastal plane. In particular, the technique was suitable for detecting salt water intrusion in a fresh acquifer, with good reliability.


Objective To observe the efficacy,safety and possible mechanism of recombinant human interleukin-11 ( rhIL-11)in chemotherapy induced thrombocytopenia of initial acute leukemia.Methods 60 initial acute leukemia patients were treated with rhIL-11 after the completion of chemotherapy at 50 μg/(kg·d), injection for 4 ~14 days.59 acute leukemia patients during the same time entered into the control group. Results The platelet counts of the treatment group after using rhIL-11 was statistically different with the control group (P 0. 05).Meanwhile, the amount of platelet transfusion in treatment group was less than those of control group (P 0.05).Major adverse events associated with rhIL-11 were fatigue, edema, nausea, callosity and so on.They were mild, reversible with drug discontinuation and easily managed.Conclusion RhIL-11 can safely accelerate the recovery of chemotherapy induced thrombocytopenia in initial acute leukemia and decrease the requirement for platelet transfusion.


In this paper, the effects of various environmental exposure conditions on concrete beams externally reinforced with carbon-fiber-reinforced polymer (CFRP) composites were studied. To evaluate the overall environmental effects on the durability of the interfacial bonding between concrete and CFRP, different commercial composite systems were investigated under various exposure conditions by using a new test method suggested previously. Results showed that the flexural strength of the beam specimens was reduced with environmental exposure. The commercial systems showed significant differences in the relative strength loss, although they were all intended for the same application, suggesting that durability is highly dependent on the epoxy system used in the composite. Under exposure to water and other fluids with different temperatures, CFRP systems employing wet lay-up composites showed high durability with the exception that one system revealed a considerable loss in strength with elevated temperature and time. A system using a precured laminate exhibited a large reduction in strength with exposure. Exposure to brackish water caused an increase in the flexural strength by virtue of buildup of barnacles, which protected the specimens from deterioration and increased the strength by acting as an additional reinforcement.


Business development is growing rapidly, giving rise to competition, resulting in every company having to struggle to create new innovations in order to be able to compete in the market. Rewards and punishments are often carried out in developing companies that one of the developing companies is PT. Tri Tunggal Prima Perkasa as a manufacturing company produces coal briquettes. Based on this, the purpose of this study is to determine the application of rewards and punishments given in improving employee performance at PT. Tri Tunggal Prima Perkasa. The research method used is a qualitative method. Data collection using interviews, observation and documentation with 3 informants. The results showed that the application of rewards at PT. Tri Tunggal Prima Perkasa in the form of salary and bonus. The punishment applied to PT. Tri Tunggal Prima Perkasa was classified as light, medium and heavy. Reward and punishment applied by PT. Tri Tunggal Prima Perkasa is still not doing well. This makes employees unmotivated and results in decreased company productivity. Rewards and punishments applied by the company should be objective, fair and given maximally to each employee to encourage employee performance motivation to be better.


In June of 1992 a boundary-layer experiment was carried out near Boardman, Oregon. The campaigns were part of a program of studies under the auspices of the US Department of Energy`s Atmospheric Radiation Measurement (ARM) program, whose goal is to improve the treatment of radiative transfer, particularly as affected by clouds, in general circulation models (GCMs) used for climate studies. One aspect of this program is concerned with the determination of appropriate lower boundary conditions for such models and the representation of subgrid-scale variability in regions where the surface conditions are not uniform. To study this problem, boundary-layer and surface properties were measured over a region of two sharply contrasting land types: a large, dry, sagebrush steppe area and irrigated farmland that formed the east, northeast, and western borders of the steppe. A combination of surface flux instrumentation, airsondes, sodars, and near-surface wind and temperature sensors was used. Measurements were carried out over the eastern portion of this region, which featured a well-defined boundary between the dry and irrigated areas. In this paper, the authors present some results from those observations and from a set of numerical simulations that address the effects of inhomogeneous surface fluxes on boundary-layer structure.

A novel high wear resistance hypoeutectic Fe–C–B alloy by hot rolling with isolated hard lumps distributed in matrix is reported. The effect of deformation on microstructure and properties of the alloy during hot rolling process was systematically investigated. The results showed that with the increase of deformation, the continuous hard phase network in the alloy was crushed into isolated hard lumps, and the properties of the alloy were improved significantly. The alloy with 66.7% deformation displayed excellent mechanical properties with the impact value of 12.6 J while its hardness was still kept at 58.6 HRC. And the wear resistance of the alloy with 66.7% deformation was 1.21 times as that of the commercial Cr20Mo high chromium cast iron.


Anthropometric measurements were done on 723 singleton Iraqi infants who were born consecutively in Baghdad Teaching Hospital. The results showed that the measurement of head circumference can be used to screen LBW babies. We suggest the use of this single measurement for practical field work by developing a tricoloured tape with bands of colours. Midwives and traditional birth attendants (TBAs) can be educated to use the colour-coded tape and refer LBW new-born infants for special pediatric care.


Road inspection and maintenance require a large amount of data collection, where the main limiting factor is the time required to cover long stretches of road, having a negative impact on the optimization of the work. This article aims to identify modern tools for road maintenance and analysis. To carry out the research, recent methodologies are used to guide the work in different stages to adequately justify the processes involved. Using unmanned aerial vehicles (UAVs), cameras, and GPS, three-dimensional virtual models are reconstructed, which are useful for extracting the necessary information since they allow for accurate replication of the captured. In this way, it is possible to obtain longitudinal profiles associated with the road, and with it, the international roughness index (IRI) is calculated, which gives results within 0.1 (m/km) of the certified official results, which shows its potential use and development.


A simple, fast and sensitive spectrophotometric method for the determination of cefaclor in pharmaceutical raw and dosage forms based on reaction with ninhydrin is developed, optimized and validated. The purple color (Ruhemenn's purple) that resulted from the reaction was stabilized and measured at 560 nm. Beer's law is obeyed in the concentration range of 4-80 µg mL-1 with molar absorptivity of 1.42 × 105 L mole-1 cm-1. All variables including the reagent concentration, heating time, reaction temperature, color stability period, and cefaclor/ninhydrin ratio were studied in order to optimize the reaction conditions. No interference was observed from common pharmaceutical adjuvant. The developed method is easy to use, accurate and highly cost-effective for routine studies relative to HPLC and other techniques.


Decision-making for autonomous robots in real world applications has to manage uncertainties in order to efficiently accomplish a mission. Some planning methods deal with uncertainty by improving the robustness of the plan embedded in the robot. In this paper, we propose a novel approach to one of these methods, contingent planning. Most of the existing approaches are limited by the computation complexity and the quality of the solutions they return. To deal with these limitations, we propose to limit the number of observations in the plan as observations involve an important cost in computation time and energy. The originality of our approach is that our contingent planner uses an underlying conformant planner, i.e., a planner that is not allowed to make observations, to compute conformant subplans and insert observations between conformant subplans only when a conformant plan cannot be computed. We evaluate this approach by comparing its results with respect to ContingentFF (Contingent Fast-Forward), a well known contingent planner, on a set of benchmarks. This comparison reveals that, even if our approach has some limitations, as it is not complete, it works quite effectively in terms of solution quality on classic benchmarks of the planning community. Keywords–contingent planning; autonomous decision-making; uncertainty.


Raman spectroscopy provides information about molecular vibrations,which are sensitive to interactions and conformations of the molecules.It enables the physicochemical features of polymers to be examined without resorting to chemical labeling and affords minimum sample preparation.Moreover,its spatial resolution can be better than 1μm the lateral plane by focusing laser beams on the samples.Therefore,the construction unit,steric configuration,crystalline structure and conformational structure of the polymer chain can be studied by the Raman spectroscopy.Such as the Surface- enhanced Raman Scattering(SERS),Variable temperature Raman spectroscopy,Confocal Raman Microscopy(CRM), Raman Mapping and Resonance Raman scattering(RRS)are widely used in physics,chemistry and biomedicine.In this review,we summarize the research progresses of chain conformation,crystalline behave,chain diffusion and phase structure of polymer based on Raman technique,and deeply attempt to explore the applications of Raman spectroscopy in the polymer.

Factors thought to be relevant to a child's cognitive development in this environment were measured at baseline when the children were 4-6 years pf age, and several were found to be associated with scores in at least one of the three cognitive tests administered to the children: the area where the children lived (site), gender, whether children received pre -school education, their HIV status, the level of parental education, height-for-age, and hemoglobin. The evidence showed a significant association between site, poor nutrition as measured by height-for-age z-scores on the one hand, and cognitive outcomes as measured by the Grover Counter Test and subtests of the KABC-11.on the other [1,2].


Recent results in genomics and proteomics and new advanced tools for gene expression data analysis with microarrays have produced so huge amounts of heterogeneous data that biologists driving comparative genomic studies face a quite complex task for integrating all relevant information. We present a new framework based on a knowledge base and semantic web techniques in order to store and semantically query a consistent repository of experimental data.


ArcelorMittal Tubarao is a traditional supplier of slabs for the production of heavy plates. In order to meet the increasing demand of slabs for this market as well as the slab surface quality requirements it was developed a study concerning transverse corner crack on slabs. This defect is detrimental to the final application and is being removed by means of slab scarfing whenever identified. This work aims to decrease the occurrence of transverse surface corner cracks on the slabs produced in continuous casting, through a better understanding of the crack formation mechanism and the secondary cooling system performance of continuous casting machine. The tests performed in thermo mechanical physical simulator were able to predict the hot ductility of steel in this study. The study promoted a greater understanding of the corner crack formation mechanism allowing the implementation of quality and process control actions with positive results in the slab surface quality. It was observed gains on processing cost, conditioning yield and rework. Finally the customer satisfaction increased by the improvement of the surface quality.


To reconstruct the tooth surface of a circular arc tooth trace cylindrical gear (CATT gear), one needs to create an accurate 3D model and investigate geometric features of the tooth profile. According to the processing principle of the rotating knife dish milling, and using the space meshing theory and differential geometry, the tooth surface equation and the tooth profile of CATT gears have been deduced. Then, the tooth surface reconstruction of CATT gears was done and a 3D model was created. Next, based on theoretical deduction, it was proven that the profile of the middle section was involute, and the other section was hyperbolic. Finally, the influences of the design parameters on the tooth profile were investigated. The general tendency is that the gear tooth thickness becomes thinner as the gear width increases and the tooth line radius decreases, and the tooth profiles of the concave and the convex tooth surface may intersect. The influences of the module need to be discussed separately. The tooth thickness deviation increases as the module increases. But the relative tooth thickness deviation is opposite. Therefore, it is suggested that RT  (3-4)b and the module should be large to improve the bearing capacity. The results of the investigation provide a reference for the design, profile modification, lubrication, and measuring of CATT gears.


We present approaches for visible and infrared video image sequence registration, useful for image fusion, target detection and recognition. For the visible and mid-infrared images of well-separated spectral bands the challenge in image registration is the feature inconsistency and low contract and noise in the infrared image background. Possibility of integrating the optical correlator into the operational systems is discussed.


Different genomic relationship (G) estimators were compared within and across populations in an admixed population. By assessing relationship coefficients separately for different populations, this study found that scaling G with current data allele frequencies across breeds increased coefficients for individuals in distant related populations, when compared to using breed allele means calculated from breed proportions. The latter however shifted most relationships towards zero or less. The predictions of direct estimated genomic values (DGV) were unaffected regardless of allele frequencies used. Relationship coefficients that combine genomic information and polygenic variation from the pedigree slightly increased the validation reliability of DGV in the current population.


We present novel and efficient methods for builtin-self-test (BIST) of FPGAs for detection and diagnosis of permanent faults in current as well as emerging technologies that are expected to have high fault densities. Our basic BIST methods can be used in both on-line as well as off-line testing scenarios, though we focus on the former in this paper. We present 1and 2-diagnosable BISTer designs that make up a ROving TEster (ROTE). Due to their provable diagnosabilities, these BISTers can avoid time-intensive adaptive diagnosis without significantly compromising diagnostic coverage—the percentage of faults correctly diagnosed. We also develop functional testing methods that test programmable logic blocks ( PLBs) in only two circuit functions that will be mapped to them as the ROTE moves across a functioning FPGA. We extend our basic BISTer designs to those with test-pattern generators (TPGs) using multiple PLBs to more efficiently test the complex PLBs of current commercial FPGAs, and prove the diagnosabilities of these designs as well. Simulation results show that our 1-diagnosable functional-test based BISTer with a 3-PLB TPG has very high diagnostic coverages—for example, for a random fault distribution, our nonadaptive diagnosis methods provide diagnostic coverages of 96% and 88% at fault densities of 10% and 25%, respectively, while the previous best non-adaptive diagnosis method of the STARBISTer has diagnostic coverages of about 75% and 55% at these fault densities.


Reducing the number of early school leavers, those who quit education without at least a high school degree, is a key objective of educational policy throughout Europe. Previous research has shown that in particular youngsters from disadvantaged families face relatively high risks of school dropout. In this paper we use data from the 2009 ad hoc module of the Labour Force Survey to examine how macro-level determinants influence school dropout risks among different social groups. Our results indicate that both the design of the educational system (tracking age, extent of vocational education) and characteristics of the socioeconomic context (poverty rate, unemployment patterns) have an impact on the social distribution of school dropout risk.


For many studies concerning foundation, such as rails and pavements, the mechanism for energy dissipation within a foundation is considered only to be by viscous behaviour. It is generally considered however that dissipation of energy in soil-type foundations takes place, in the main, due to internal friction damping, known as hysteretic damping. Also quite often the simpler Euler- Bernoulli beam formulation is used, hence excluding the effects of shear rigidity and radius of gyration of the beam. In this work by the use of the Timoshenko beam formulation these effects are included as it the use of a two-parameter hysteretic damped foundation. The investigation includes when the beam experiences a moving load with constant or harmonic amplitudes. Hamilton's principle is used to formulate the two governing equations when are then transformed into two algebraic equations by uncoupling and the use of a double Fourier transform w.r.t. moving space and time. The beam deflection is obtained using inverse fast Fourier transform and the solutions obtained are compared with bot Winkler and Pasternak foundation results found in the literature. Calculations are made which investigate the effect of the spatial distribution of the loading and the effects of the beam and foundation properties on the deflected shape, the maximum displacement, critical frequency and the velocity. The results can be used to assess performance and safety aspects of railway and highway structures.

Abstract This paper examines the role of the Brazilian service of Support for Micro and Small Enterprises – SEBRAE in Brazil in recent decades organizational environment and aims to contribute to the identification and description of your activity, as a way to understand the organizational transformations of the micro and small companies. Achieving this goal, a field survey was carried out in which were raised institutional documents, records and interviews with professionals connected to the institution. Qualitative analysis were made in the material through five sections: products, agents, customers, structure/strategy and scenario. From the chronological analysis of the data, they were organized in three distinct periods. Each of these temporal spaces significant for the institution's understanding. In this way, it seeks to portray the processes of transformation and redirection through which SEBRAE has passed in each period, from the foundation to the 21st century, and its forms of intermediation of micro and small Brazilian companies.

Two broad scenarios for extended linear Lorentz transformations (ELTs) are modeled in Section 2 for mixing subluminal and superluminal sectors resulting in standard or deformed energy-momentum dispersions. The first scenario is elucidated in the context of four diverse realizations of a continuous function , with and , which is fitted in the ELT. What goes in the making of the ELT in this scenario is not the boost speed , as ascertained by two inertial observers in uniform relative motion (URM), but . The second scenario infers the preexistence of two rest-mass-dependent superluminal speeds whereby the ELTs are finite at the light speed . Particle energies are evaluated in this scenario at for several particles, including the neutrinos, and are auspiciously found to be below the GKZ energy cutoff and in compliance with a host of worldwide ultrahigh energy cosmic ray data. Section 3 presents two broad scenarios involving a number of novel nonlinear LTs (NLTs) featuring small Lorentz invariance violations (LIVs), as well as resurrecting the notion of simultaneity for limited spacetime events as perceived by two observers in URM. These inquiries corroborate that NLTs could be potent tools for investigating LIVs past the customary LTs.


Ultrabroadband electro-optic sampling with few-cycle optical pulses is known to be an extremely sensitive technique to detect electric field amplitudes. By combining this method with dual-comb spectroscopy and with a new class of ultrafast lasers, we perform high-resolution (<10 MHz, 0.0003 wavenumbers) spectroscopic measurements across the whole frequency range of 1.5 to 45 THz (6.6-200 microns) with an instantaneous spectral coverage exceeding an octave (e.g., 9-22 microns). As a driving source, we use a pair of highly mutually-coherent low-noise frequency combs centered at 2.35 microns produced by mode-locked solid-state Cr: ZnS lasers. One of the two combs is frequency downconverted via intrapulse difference frequency generation to produce a molecular sensing comb, while the second comb is frequency doubled to produce a near-IR comb for electro-optic sampling (EOS). An ultra-low intensity and phase noise of our dual-comb system allows capturing a vast amount of longwave spectral information (>200,000 comb-mode spectral lines) at up to a video rate of 69 Hz and with the high dynamic range limited by the shot noise of the near-IR EOS balanced detection. Our long-wavelength IR measurements with low-pressure gases: ethanol, isoprene, and dimethyl sulfide reveal spectroscopic features that had never been explored before.

Introduction In 2002, the Health Professions Council of South Africa (HPCSA) made continuing professional development (CPD) a mandatory requirement for all registered healthcare practitioners. However, the latest (2017/2018) HPCSA report states that there is still a generally low level of compliance to CPD requirements by emergency medical care practitioners (EMCPs) nationwide. Methods This was a descriptive study that made use of a questionnaire survey administered to 261 EMCPs. Results Of the 261 questionnaires that were distributed, 247 were returned, giving a response rate of 94.6%. More than half (50.6%) of the EMCPs indicated that they lack knowledge on the HPCSA-recommended CPD requirements for EMCPs, and 54% stated that they do not have CPD portfolios. EMCPs listed the factors that hinder attendance of CPD activities: lack of information about the CPD activities (72.7%); cost of attending CPD events (70.6%); limited availability of CPD activities (70.6%); transportation problems (68.5%); timing of CPD activities (68.2%); difficulty in getting nominated to attend CPD activities (65.5%); and lack of personal funds (65.1%). Furthermore, EMCPs indicated that lack of internet access (45.5%) and poor knowledge of how to use the internet (15.2%) hinder them from accessing the internet for professional learning. Conclusion To provide the best care to patients, healthcare professionals must commit to lifelong learning. Participating in CPD activities has been endorsed as a means for maintaining and updating professional competence. Identifying and alleviating barriers that limit engagement in CPD activities will ensure that EMCPs attain the required professional competence.

Summary - The inoculauon of Prunus cerastfera hardwood cuttings in containers by a population of Me/oidogyne arenaria was done by transfering roots and soil of a tomato plant grown in pot that was inoculated 2 months before with 500 juveniles (2) of this nematode. Containers with a non host clone of P. cerasifera were first used to estimate the release of J2 inoculum into the soil from rotting tomato roots. Mean total inoculum produced in one container was 160 000 J2s + eggs. Juvenile inoculum recovered monthly in Prunus soil varied between 5000 and 17 000 ail along the 4-month experiment thus providing a high and durable inoculum pressure. Then eleven other P. cerasifera clones (five hosts and six non hosts) inoculated with the same method were harvested after 4 months to determine suitability of several criteria of evaluation of resistance. Gall index was highJy significantly correlated with the 10glO(x + 1) transformed numbers of the different nematode stages in roots of host clones. The best linear correlauon was observed with females, followed by eggs and J2s. Presumably because of the extracuon technique, gall index, root eggs and root J2s resulted the best criteria to differentiate sratistically weakly-galled clones from non host clones. Gall index is therefore a good crirerion ro evaluare resistance in P. ce ras ife ra.


The 1995 pay award is an insult both to the profession of nursing and to the patients for whom we care. This government has never cared and this is simply another nail in the coffin of the NHS.


At least two genes are responsible for lactate dehydrogenase (LDH) synthesis in the tissues of eighteen species of flatfish (Pleuronectiformes). The relative activity of these genes is markedly skewed with LDH‐A being present in much larger amounts and in a wider variety of tissues than LDH‐B. Certain flatfish exhibit a single LDH‐A while others have five forms of this tetramer. Molecular hybridization experiments demonstrate that these five tetramers have two distinguishable subunits. These subunits were purified and subjected to amino acid analysis, peptide mapping, kinetic and immunochemical analysis and shown to be very similar, perhaps identical, in primary structure. Treatment with reducing reagents failed to interconvert them. LDH‐B was partially purified and shown to be kinetically and immunochemically distinct from LDH‐A. As is true for many other fish, additional LDH isozymes are obseved in eye and brian tissues. These results show that the flatfish genetic information for LDH synthesis is similar to that of other fish, and flatfish LDH A and B subunits are homologous to those of other vertebrates.

ZnSe, ZnSSe and ZnCdSe films and ZnSSe/ZnSe and ZnSe/ZnCdSe superlattices were grown by molecular beam epitaxy. The structural and optical properties were studied by X-ray diffraction and photoluminescence. The temperature dependence of the photoluminescence shows that the activation energy (Eact) is 17meV for the ZnSSe/ZnSe superlattice and the result can be explained by the small conduction band offset. For the ZnSe/ZnCdSe superlattice, we get the Eact = 41meV from the result of the temperature dependence of the PL. It is shown that the band offset of the ZnSe/ZnCdSe superlattice is enough to confine the carriers. We can design the structures of blue-green laser diodes based on these results.
