Razorback football is an obsession in Arkansas, from the Ozarks to the Delta, and a rallying point for displaced Arkansans everywhere. The whole history of Hog football is covered in this lively chronicle. The story begins in 1894, when the playing field was a patch of spriggy dirt and the team players were derided as "thugs, pug-uglies, and roughnecks" by a local newspaper. For a time, Arkansas suffered sporadic losing seasons as the only non-Texas team in the Southwest Conference. Then Frank Broyles turned the program around and won a national championship in 1964. Later, Lou Holtz stunned the nation with a Razorback Orange Bowl victory over Oklahoma in 1978. In the 1990s, the Hogs have arrived in the Southeastern Conference, reentered national rankings, and gained bowl invitations. All the great names and major players are here, including Hugo Bezdek, Steve Creekmore, Wear Schoonover, John Barnhill, Preston Carpenter, Lance Alworth, Ken Hatfield, Bobby Crockett, Jim Lindsey, Jerry Jones, Bill Montgomery, Chuck Dicus, Ben Cowins, Ron Calcagni, Billy Ray Smith, Quinn Grovey, Danny Ford, Madre Hill, J. J. Meadors, and many more. Complete appendices detail the game schedules and statistics, the roster of coaches, the bowl game results, a list of all the lettermen, and the statistics of selected players.


Having a multiplier input image data is input, and the multiplier output adder input, a memory storing correction data to be supplied to the multiplier and the adder, and a control unit. In the memory, the respective correction data for the plurality of luminance correction points of one display dot are prepared, and the correction data includes correction data for addition and for multiplication for the video data. Under the control of the control unit, to the image data corresponding to each display dot at the multiplier, respectively multiplied by the correction data for multiplication (ST1, ST2), the video data of the multiplication result at the adder further adds or subtracts the correction data for addition and subtraction (ST3), and outputs the image data obtained by this addition process in the corresponding display dot (ST4).


1. This paper draws heavily from a paper prepared by Julia Sagebien titled "Foreign Trade and Investment in Cuba After February 24, 1996: Life Between a Rock and a Hard Place," delivered in Ottawa on May 17, 1996. However, the views presented here are exclusively those of the author. This paper characterizes the situation that Cuba and foreign investors, alike, find themselves as a result of the adoption by the United States of the Helms-Burton Act. In particular, the paper focuses on dilemmas facing Canadians in maintaining stakes in Cuba and launching challenges to Helms-Burton. The paper is divided into three parts: the Canadian foreign policy framework toward Cuba, the effect of Helms-Burton on Canadian commercial interests in Cuba, and concluding remarks.


New and improved data on the gravitational lens systems discovered so far are compared with the theoretical predictions of Gott, Park, and Lee (1989, GPL). Systems lensed by a single galaxy, compatible with assumptions of GPL, support flat or near-flat geometry for the universe. But the statistical uncertainty is too large to draw any definite conclusion. We need more lens systems. Also, the probability of multiple image lensing and mean separation of the images averaged over the source distribution are calculated for various cosmological models. Multiple-image lens systems and radio ring systems are compared with the predictions. Although the data reject exotic cosmological models, it cannot discriminate among conventional Friedmann models yet.


markdownabstractZoonoses, i.e. diseases that are transmissible from animals to humans, have received increasing scientific and public attention in recent years. A comprehensive literature review identified 60% of human pathogens as zoonotic, of which 12% constitute so-called 'emerging infectious diseases'. This term denotes previously unknown diseases that cause outbreaks or known diseases that cause significantly more infections in humans today than in the past two decades.

This thesis investigates animal influenza viruses as a topical example of zoonotic, emerging infectious diseases. I argue that surveillance at the human-animal interface can be improved by implementing novel serological screening tools. Furthermore, I will recommend that a One Health-based surveillance system, spanning both human and animal health, needs to be put in place.


In this article, a new approach based on fuzzy systems is used for solving time delay fractional order optimal control problems. The fractional derivatives are considered in the Atangana–Baleanu sense that is a new derivative with the nonsingular and nonlocal kernel. By means of the calculus of variations and the formula for fractional integration by parts, the necessary optimality conditions associated to the time delay problem is derived. In order to solve the obtained optimality system, the solution of the system is first approximated by fuzzy solutions with adjustable parameters. The optimality system is then reduced to an unconstrained optimization problem by using appropriate error function. A learning algorithm is also presented to achieve the parameters of these fuzzy solutions. The efficiency and accuracy of the proposed approach are assessed through some illustrative examples of the time delay fractional optimal control problems.


A sterile hemostatic agent composed of purified porcine-derived gelatin. In regional chemotherapy, absorbable gelatin sponge may be used to embolize arteries in the region of a tumor in order to block or retard blood flow; this blockage results in a locally increased concentration of chemotherapeutic agents delivered to the tumor when chemotherapeutic agents are infused into the embolized arterial circulation upstream of the blockage.


Pattern classification is an important task in speech recognition and speaker verification. Given the feature vectors of an input the goal is to capture the characteristics of these features unique to each class. This paper deals with exploring Auto Associative Neural Network (AANN) models for the task of speaker verification and speech recognition. We show that AANN models produce comparable performance with that of GMM based speaker verification and speech recognition.


Since 1980, by a series of laws and executive orders, the resources in federal laboratories have been made increasingly available to private industry via technology transfer efforts in support of the National Competitiveness Objectives. The author explains how these resources can be accessed, with particular emphasis on Los Alamos National Laboratory.<<ETX>>


PURPOSE: To eliminate the need for training for maintenance for important application by arraying and dividing a multilevel signal into elements and selecting divided elements which meets difference measurement reference. CONSTITUTION: Successive frames of video information are sent to a subband analytic block 110 where time-space components are generated and are sent to an energy measurement block 120. Then an image is divided into plural time-space subbands, energy outputs of the respective time-space subbands are compared with a prescribed threshold value and in a geometric vector quantizer 150, the subband signals after the threshold value is processed are compared systematically with vectors stored in a code book 160. Vector suffixes for respective vectors selected as the best coincidence are sent to a multiplexer 190 together with absolute values M1 and M2 and in the multiplexer 190, this information is combined with DPCM information from a DPCM encoder 170.


This essay is intended as an exercise in the understanding of some of Martin Heidegger's important ideas, especially in the notion of dread by the philosopher. In order to elucidate these ideas, a philosophic reading of Vladimir Nabokov's short story Terror is done. The story is presented here together with an approach between the experience of terror, as described in the story, and that of dread, as described by Heidegger. This approach is to be explained throughout the article in which other questions concerning Heidegger's thought will appear and be considered.


To present three cases of slow‐release verapamil poisoning that demonstrate the prolonged absorption of the drug and the role of polyethylene glycol and high‐dose calcium in management. Clinical features: Three patients with slow‐release verapamil poisoning are presented. An 18‐year‐old woman took 2.3 g and developed hypotension and bradyarrhythmias 18 hours after ingestion, despite gastric lavage and administration of charcoal at three hours. A 23‐year‐old woman took 4.8 g and presented two hours later clinically unaffected. A 44‐year‐old woman presented 24 hours after taking 15–20 g. She had a systolic blood pressure of 50 mmHg, no measurable diastolic blood pressure and bradyarrhythmias. Intervention and outcome: Case 1 responded to administration of 30 g of calcium and fluids intravenously. Case 2 was given polyethylene glycol on admission which resulted in passage of a tablet bezoar and no toxicity. Polyethylene glycol was ineffective in Case 3. She responded initially to high doses of calcium and other treatments, but subsequently died of hypotension and cardiac conduction block 39 hours after the overdose. Conclusion: The severity of poisoning with slow‐ release verapamil warrants aggressive pre‐emptive treatment. Polyethylene glycol should be used routinely irrespective of the clinical state. High doses of calcium may be required to treat conduction block and hypotension.


Identifying feature requests and bug reports in user comments holds great potential for development teams. However, automated mining of RE-related information from social media and app stores is challenging since (1) about 70% of user comments contain noisy, irrelevant information, (2) the amount of user comments grows daily making manual analysis unfeasible, and (3) user comments are written in different languages. Existing approaches build on traditional machine learning (ML) and deep learning (DL), but fail to detect feature requests and bug reports with high Recall and acceptable Precision which is necessary for this task. In this paper, we investigate the potential of transfer learning (TL) for the classification of user comments. Specifically, we train both monolingual and multilingual BERT models and compare the performance with state-of-the-art methods. We found that monolingual BERT models outperform existing baseline methods in the classification of English App Reviews as well as English and Italian Tweets. However, we also observed that the application of heavyweight TL models does not necessarily lead to better performance. In fact, our multilingual BERT models perform worse than traditional ML methods.


Welding processes on plates involve complex physical and chemical phenomena which make mathematical modeling difficult. Although coupled thermal-mechanical-metallurgical effects are important, good results can be found when numerical models based on heat transfer equation and governing equations of the structural behavior are used. In general, the thermal field is independent of the structural one since procedures can be carried out in one-way (thermal-structural), without the need of coupling. Adequate analyses of welding processes with material deposit have used the element birth and death technique, which considers activation of finite elements that belong to filler material as the heat source moves. This paper describes numerical analyzes of multi-pass butt welds with V chamfer of AISI 304L stainless steel by using the conventional MIG process. The plates are 9.5 mm thick, 200 mm long and 50 mm wide. Numerical simulations are carried out by Ansys Multiphysics® software which considers convection and radiation dissipations and temperature dependence of material properties (thermal conductivity, specific heat and specific mass). The moving heat source is the Gaussian type. The fusion zone shape, obtained by the experiments developed at a welding laboratory at the FURG, located in Rio Grande, RS, Brazil, is compared with numerical ones. One of the drawbacks of birth and death element technique application is the fact that the elements which belong to the intermediate passes have elements of other passes as their boundary neighbors, preventing the radiation effects from being considered. Therefore, results of two algorithms are compared: one of the algorithms adopts the classical method, in which the radiation is impeded by the elements that belong to intermediated passes, whereas the other one enables the radiation effects to happen. Results pointed out some differences which show the importance of the radiation effects on the region of material deposition.


We report a case of an 11-month-old girl who was referred to us for fever, difficult feeding with progressive weight loss and a painful ulcer on the ventral surface of the tongue. Her clinical history was characterised by a perinatal hypoxic-ischaemic brain injury. The intra-oral examination revealed an ulcerative lesions extending from the tip to the ventral surface of the tongue. It was ovoid, well circumscribed, with raised and indurated edges and with a yellowish fibrinous base (Fig. 1a,c – lower arrow). Biochemical analysis, immunological and genetic studies were normal; cultivation of the lesion revealed flora saprophyte. As neurological examination revealed a multifocal dystonia including abnormal movements of the oro-facial musculature that caused the impact of the tongue between the lower central incisors, the diagnosis of 'late Riga-Fede disease' (RFD) was considered. The electroencephalogram (Fig. 1b) showed bihemispheric slow frequency rhythms, while the brain magnetic resonance imaging showed a thinning of the


This article argues that the new judicial federalism, the increased reliance by state judges on state declarations of rights to secure rights unavailable under the U.S. Constitution, represents not a return to an earlier federalism but rather something new. Although the basis for a state civil liberties jurisprudence had long existed, the "discovery" of state constitutional guarantees did not occur until the Warren Court pioneered an approach to civil liberties that state courts could emulate. This "discovery" has led to only intermittent reliance on state guarantees. Nonetheless, it is unlikely that state judges will return to the total deference tofederal rulings in civil liberties cases that characterized preceding decades.


At present, the empirical formulas of flight parameters are not accurately fitted for different aircraft types, and the traditional black-box algorithms don't express the flight parameter correlation quantitatively. To address the above problems, a flight simulation parameter identification method bases on Quick Access Recorder (QAR) data is proposed. Based on the polynomial fitting algorithm, the method adds weight coefficients to assign the weight of input parameters in the algorithm and calculates the weight coefficients of different input parameters using Spearman Rank correlation coefficients. Designing the binary polynomial and solving the optimal polynomial coefficients based on the improved algorithm. The simulation results show that the method effectively reduce the simulation error.

A novel method for online steam condenser fouling cleaning is proposed in this paper. In the approach, high pressure cleaning is chosen as the main method, chemical cleaning is applied to complement and this cleaning method is achieved by a new autonomous cleaning robot. In this paper, firstly, the robot system structure is designed which consists of mechanical and electrical structure. Secondly, the distributed control system is used to improve cleaning efficiency. Based on these, the cleaning control strategy based on fuzzy-gaussian neural network is presented and the BP algorithm is adopted to train the network weights. Then, the simulation results show that the proposed control strategy has better robustness and dynamic performance than traditional fuzzy control, which can not only reduce the phenomenon of chattering in effect, but also has good robustness and dynamic performance. Hence, the control strategy is very fit for underwater robotic arm control.


The invention provides an ultrasonic diagnosis device which comprises each hardware unit and each structural frame arranged outside each hardware unit. Each hardware unit comprises a display unit, a control signal input unit and a host unit, wherein the display unit and the control signal input unit are respectively electrically connected with the host unit. Each structural frame comprises a display unit frame, an operating console frame and a main supporting frame. All the hardware units except the display unit are arranged in one structural frame in a uniform and concentrated mode. Due to the fact that the hardware function units are concentrated in one structural frame, the function units are connected more compact and are better in installability and maintenance, a connection wire harness between the function units is shorter, and the corresponding EMC problems are less.


New genetic technologies have enabled us to begin the process of unravelling the underlying genetic architecture for complex traits. We report on the identification of quantitative trait loci (QTL) for seven fatness traits at various depots derived by computed tomography (CT) scanning. Progeny (n=164) from a backcross between Merino and Awassi sheep were used in an attempt to exploit the differences that exist in the fat attributes between the two breeds. A genome-wide scan using 117 informative microsatellite markers was used. With the exception of fat depth and %internal fat, all fat traits were found to be highly correlated. Six key QTL areas were detected with one in common to all traits highlighting the polygenic nature of fatness.


This article describes the lexicography of psychic vocabulary in a diachronic aspect. For a long time, synonymic chains were the most common way of its interpretation, examples being a more recent lexicographic invention. However, both methods are concept-oriented. Unfortunately, neither of them solved the problems of a dictionary aimed at intercultural relations. The current globalization and informatization triggered non-traditional interpretations that describe not the concept, but a prototypical situation, which is associated with it. This study introduces several principles of interpreting the psychic vocabulary. These principles relate to the language, semantics, parameters, and structure of the semanteme. The approach is based on the connection between language and perception. For instance, the psychic vocabulary encodes the reaction of the heart as an organ ( love, rage, serenity, peace, disgust ). Therefore, the psychic vocabulary is different from the abstract vocabulary (good, evil, justice, democracy ), which does not encode bodily reactions. The author believes that the seme 'heart' is implicitly present in the semantic structure of the psychic vocabulary. Scientific literature features the lexeme of  heart in comparative, conceptual, and metaphorical aspects, but not as an implicit component. Thus, the denotative space of the psychic vocabulary is a complex cognitive construct structured as 'assessment / reaction of the heart / desire', represented by the archisemes of feelings, emotions, and states. Words united by these archisemes demonstrate different valency, word-building, and pragmatic properties. In terms of the structure of the psychic polysemy, feelings and traits have the potential to develop the meaning of states, and words that denote physiological states generate figurative meanings of mental states.


Metastasis of vaginal leiomyosarcoma to the thyroid gland is an extremely rare event. Here, we report a case of thyroid metastasis of vaginal leiomyosarcoma. A 65-year-old female patient presented with a multinodular toxic goiter. 5 years earlier the patient has undergone a radical vaginal resection followed by chemotherapy due to high-grade vaginal leiomyosarcoma. Fine-needle aspiration cytology of the right thyroid lobe was suggestive of the benign thyroid lesion. As the diagnosis was not clear, following a multidisciplinary team discussion the decision was made to proceed with a total thyroidectomy. Pathologic assessment of the tumor confirmed thyroid metastasis of vaginal leiomyosarcoma.


In this article, we examine the role of academic journals in the development of the field. In particular we focus on JEAH as an illustrative example of an academic journal that has, from the outset, reflected and portrayed intellectual developments in educational administration and history. We argue that academic journals, in effect, are one of the most visible and ostensibly powerful forms of knowledge production that can be a highly political and contested process. Moreover, attempts over the past few decades to utilise qualitative or quantitative measures to weigh and measure the (apparent) status and impact of academic journals serve to invoke ratings wars that can only rebound to the disadvantage of scholarship in discipline of education and the field of educational administration and history.


Organizations have increasingly invested money in information technology IT in order to improve their agility. It is generally believed that organizations with greater IT investment tend to be more agile to response to environmental changes. However, the issue of whether IT is an enabler or impeder of organizational agility still remains unresolved. Drawing upon resource-based view theory and the literatures of information systems and supply chain management, the authors develop and test a theoretical model that integrates IT capability, supply chain capability and organizational agility. The authors propose that IT capability enables the development of a higher level of supply chain capability which is embedded within inter-firm processes and in turn enhances organizational agility. Structural equation modelling is employed to test their theoretical conceptualization of 310 Australian fast-growth small-to-medium enterprises across different industrial sectors. The results show that IT capability does contribute to firm agility through enhancing inter-firm supply chain processes such as integration, information sharing and coordination. This research highlights the role of IT-enabled intermediated processes and the ways in which IT is used by firms to enhance core business processes.


Streptococcus agalactiae is one of the main agents causing mastitis in dairy cattle, with important implications for humans; whereby the diagnosis, control and prevention of this microorganism is fundamental to animal and human health as well for the economy. The objective of this work was to detect the presence of S. agalactiae in milk from cattle herds affected by mastitis. Five hundred and seventy-four samples of milk were collected from quarters affected with mastitis (840 production cattle of Siboney de Cuba, Holstein and Jersey breeds of 14 dairy farms in western Cuba). Bacteriological diagnosis was performed in all samples. DNA and PCR were extracted with primers that amplified a segment of the 16S-23S rRNA intergenic region, from colonies with morphological characteristics and biochemical tests indicative of S. agalactiae . The 43.45 % of animals showed symptoms of clinical or subclinical mastitis. In 57 samples (9.97 %), colonies characteristic of S. agalactiae were isolated, and 43 (75.43 %) were positive by PCR. Of the latter, 26 (60.46 %) corresponded to quarters with three crossings, 14 (32.55 %) to two crossings and 3 (6.97 %) to clinical rooms. S. agalactiae was isolated in eight dairy farms and the most affected breeds were Holstein and Siboney de Cuba. Strains of S. agalactiae were isolated and identified in mastitis-affected cows, indicating the need for programs to control mastitis caused by S. agalactiae to mitigate the effects caused by this microorganism on human-animal-environment interfaces.


This paper analyses patterns in beliefs about the implementation of wind power as part of a geographical comparison of onshore wind power developments in the Netherlands, North-Rhine Westphalia and England. Q methodology is applied, in order to systematically compare the patterns in stakeholder views on the institutional conditions and changes in the domains of energy policy, spatial planning and environmental policy. Three factors represent support for wind power implementation from fundamentally different perspectives. The fourth perspective is critical opposed to wind power developments as well as critical to the manner in which wind projects are proposed, planned and implemented. These four perspectives exist across the geographical cases; however, some perspectives are prominent in one case and marginal in another. This relates to different legacies and varying implementation achievements in the three cases. The analysis shows that an approach that focuses on implementing as much wind power as possible, relying on technocratic reasoning and hierarchical policies is in practice the least successful, whereas collaborative perspectives with more emphasis on local issues and less on the interests of the conventional energy sector were particularly dominant in the most successful case, North-Rhine Westphalia.


Finding a peripheral tissue biopsy site to diagnose early PD would be of value for clinical care, biomarker validation, and as research enrollment criteria. Whereas autopsy and advanced PD studies suggest that the submandibular gland is an important biopsy site, there are no studies in early PD. The aim of this study was to determine whether needle biopsy of the submandibular gland reveals Lewy type alpha‐synucleinopathy in early PD.

Despite gains in May's General Election, women remain heavily under-represented in British politics. Meryl Kenny examines the evidence and asks if the time has come for gender quotas to deliver real change.


Why are some municipalities constrained and others not in using the new EU opportunities for subnational government? With this leading question, the paper considers the impact of the EU on Dutch local government politicaladministrative institutions. The key explanation of why this impact varies from municipality to municipality involves the actual receipt of EU funds. Then not only 'absorption' but also 'organizational adaptation' and in some cases 'proactive attempts' are institutionalized. The bigger a municipality, and possibly the worse its social economic position, the more it makes use of EU opportunities. Location in a border region does not appear to be a factor that can explain variations among municipalities.


The Colonel Blotto game, proposed by Borel in 1921, is a fundamental model of strategic resource allocation. Two players allocate an exogenously given amount of resources to a fixed number of battlefields with given values. Each battlefield is then won by the player who allocated more resources to it, and each player maximizes the aggregate value of battlefields he wins. This game allows modeling many practical problems of resource allocation in various strategic settings ranging from international war to competition for attention in social networks; it is particularly useful in security to model the allocation of defense resources on different potential targets. The scope of applications, however, has been limited by the lack of solutions of the game in realistic scenarios. Indeed, despite its apparent simplicity, the Colonel Blotto game is very intricate and it remains unsolved in the case with asymmetric players (i.e., with different resources) and with an arbitrary number of battlefields that can have different values. In this paper, we propose a solution of the heterogeneous Colonel Blotto game with asymmetric players and heterogeneous battlefield values, under the assumption that there is a sufficient number of battlefields of each possible value relative to the players' resources asymmetry. In particular, our assumption implies that there must be at least three battlefields of each possible value. Then, we characterize the unique equilibrium payoffs and univariate marginal distributions, along with the proof that there exist n-variate joint distributions with such marginals. Our results expand the scope of potential applications of the Colonel Blotto game, and mark a new step towards a complete solution of the game.


Triangle tests were used to detect possible differences in the aroma of subcutaneous fat of growing pigs receiving de-oiled herring offal silage as a protein supplement at high (HS) and medium (MS) levels, i.e. at levels of 150 and 75 kg t−1 dry matter (DM), when compared with samples from matched controls. Tests were carried out on samples from pigs slaughtered at 60 and 90 kg. Statistically significant differences in the aroma of subcutaneous fat were detected at both feeding levels (HS and MS) and at each slaughter weight (60 and 90 kg). Correct identification of the odd samples was 60% in pigs slaughtered at 60 kg at both feeding levels. At 90 kg slaughter weight, there were 56 and 76% correct identifications at HS and MS levels, respectively. Paired Comparison (Preference) tests were used to determine if such differences were associated with flavour defects and consequent loss of palatability. Roasted pork joints and pork/rusk loaves from HS and MS pigs were compared with matched controls (HC and MC). As a result of these tests it was concluded that detectable differences from controls in aroma of subcutaneous fat in samples from HS and MS pigs were not associated with alteration in consumer preference for cooked meats. There was no evidence of taint in meats from either HS or MS groups.


The new compounds, Sr6Sb6S17, Ba2.62Pb1.38Sb4S10, and Ba3Sb4.66S10 were prepared by the molten polychalcogenide salt method. Sr6Sb6S17 crystallizes in the orthorhombic space group P2(1)2(1)2(1) with a = 8.2871(9) A, b = 15.352(2) A, c = 22.873(3) A, and Z = 4. This compound presents a new structure type composed of [Sb3S7]5- units and trisulfide groups, (S3)2-, held together by Sr2+ ions. The [Sb3S7]5- fragment is formed from three corner-sharing SbS3 trigonal pyramids. The trisulfide groups are separated from the [Sb3S7]5- unit and embedded between the Sr2+ ions. Ba3Sb4.66S10 and Ba2.62Pb1.38Sb4S10 are not isostructural but are closely related to the known mineral sulfosalts of the rathite group. Ba3Sb4.67S10 is monoclinic P2(1)/c with a = 8.955(2) A, b = 8.225(2) A, c = 26.756(5) A, beta = 100.29(3) degrees, and Z = 4. Ba2.62Pb1.38Sb4S10 is monoclinic P2(1) with a = 8.8402(2) A, b = 8.2038(2) A, c = 26.7623(6) A, beta = 99.488(1) degrees, and Z = 4. The Sb atoms are stabilized in SbS3 trigonal pyramids that share corners to build ribbonlike slabs, which are stitched by Ba/Pb atoms to form layers perpendicular to the c-axis. These materials are semiconductors and show optical band gaps of 2.10, 2.14, and 1.64 eV for Sr6Sb6S17, Ba3Sb4.66S10, and Ba2.62Pb1.38Sb4S10, respectively. Raman spectroscopic characterization is reported. Sr6Sb6S17, Ba3Sb4.66S10, and Ba2.62Pb1.38Sb4S10 melt congruently at 729, 770, and 749 degrees C, respectively.


A new analytical method for optical measurements used to determine time- and spatially-resolved effects in shocked materials is described. This method is quite general and may be applied to a variety of spectroscopic techniques. We apply this method to the interpretation of time-resolved Mie scattering spectroscopy in shocked benzene, showing the effects of nucleation of nanometer-size diamond particles as a separate condensed phase in the shock-reacted material.


The embodiment of the invention discloses a safety seat state inspection method and device. The method comprises the steps of acquiring the state parameters of a changed state when it is monitored during vehicle traveling that the state of a safety seat changes, inspecting whether the state parameters are abnormal, and sending first warning information related to the changed state to a user terminal if yes. By the adoption of the embodiment, the abnormal state of children on a vehicle can be learnt by a user during driving, and the probability of danger to children during driving is reduced.

Pharmacogenomics is a promising field which increasingly influences medicine and biomedical research in many areas. The aim of this article is to review recent advancements in the understanding of genetic polymorphisms and their influence on interindividual variability in drug response. Also, the main variabilities in drug response according to sex differences will be discussed. The translation of pharmacogenomics into the clinical routine as well as the challenges of achieving the goal of personalized medicine are also discussed. The role of pharmacogenetic tests in pediatrics has not been well defined yet, but it is clear that those tests could help in resolving some issues regarding the administration of drugs to children. At the conclusion, the foremost ethical, social and regulatory issues regarding the translation of pharmacogenomics into clinical practice and future perspectives in the field will be discussed.


Enterpises with inflexible production structures can no longer survive in a turbulent market, as they cannot react to changes that would lead to their development. In order to satisfy specific costumer needs related to quality, quantity, cost and delivery terms, it is necessary to restructure the existing enterprises according to the Taylor principle. One of reconstruction possibilities is the implementation of new co-operation forms that lead to virtual enterprises i.e. changeable networks. A changeable netvork can only achieve efficiency by means of a modern information and communication technology. This paper presents an idea of a changeable network that can be acceptable for all participants within a virtual enterprise.


Using analytically pure Bi2O3 and Er2O3 as raw materials, the precursor of Bi and Er can be precipitated by reverse titration co-precipitation method, and the adequate pH value for co-precipitation was also analyzed. Bi0.75Er0.25O1.5 nano-powder was obtained after calcining this precursor at 500C for 3h. High temperature XRD results showed that this nanopowder was mainly in  form, with an average grain size of 10nm calculated by Scherrer Equation, which transformed into  form completely at 650C. According to the thermodynamic calculation, the suitable temperature and partial pressure of oxygen was chose. Finally, dense -Bi0.75Er0.25O1.5 solid electrolyte was sintered at 500C (measured temperature) for 1min, with a relative density of 96% and an average grain size of 18nm.


Powdered cinnamon foams badly on attempted steam distillation. It has been demonstrated that preliminary iterative evacuation of the aqueous mixture allows smooth distillation of cinnamaldehyde (I).


Observations at 10 and 20 microns with about 5 arcsec resolution are presented of the central, approximately 13 arcsec diameter region of the A5 dwarf Beta Pictoris. These observations resolve the inner disk and provide important constraints for models of the star and a basis for removing some of their ambiguities. The evidence indicates that submicron-sized grains emit much of the excess 10 and 20 micron radiation from the star. The characteristics of the dust are discussed, and the possibility that comets form the dust reservoir is considered.

Editor A 23-year old female suffering from Crohn's disease (CD) presented with a hemorrhagic crusted plaque on the tip of her nose. Based on histology, she had been initially diagnosed with metastatic Crohn's disease (MCD) and underwent immunosuppressive therapy with azathioprine, adalimumab and infliximab. Mycobacterium marinum was cultured from a biopsy of the nose and we started a therapy with minocycline, which was later switched to clarithromycin due to disease progression. After two months of therapy with clarithromycin a complete regression was achieved. To our knowledge, this is the first case in the literature, in which the immunosuppressive treatment was continued during antibiotic therapy. Maybe, in other cases, the treatment failure under immunosuppressive treatment could be explained with treatment failure of antibiotics such as tetracycline. Thus, in some patients a change of antibiotics rather than a discontinuation in the immunosuppressive therapy should be considered.


As part of the Comprehensive Spending Review (CSR), the DTI wish to carry out a review the support that it gives to Citizens Advice and Citizens Advice Scotland, to consider that those organisations play in the provision of information and advice, particularly vulnerable sections of society. The DTI review will consider the ways in which information advice can be given, including through helplines and web based services. To inform review, the DTI commissioned research to consider provision of information and practice in four other countries. This report sets out the findings from this brief study.


This paper demonstrates a validation of the junction wire network model implemented into the TLM solver based on the cylindrical grid. A simple cylindrical cavity resonator with embedded monopole and loop antennas is used as a simulated structure. An excellent agreement between the simulated S parameters obtained by the 3DTLMcyl solver based on the cylindrical mesh and GGI-TLM solver based on the cubic mesh is achieved.

The number of miles traveled each year by the U.S. large-truck population is a topic of interest for many reasons, one of which is safety. Although the number of accidents involving large trucks may be easily calculated from accident data, it is often more informative to know their risk of accident involvement per mile of travel. This requires accurate travel data. Compared in this paper are three sources of truck travel data: the Truck Inventory and Use Survey conducted by the Bureau of the Census; the National Truck Trip Information Survey conducted by the University of Michigan Transportation Research Institute; and annual estimates published in "Highway Statistics" by the Federal Highway Administration. Each data source yields different estimates of annual travel by large trucks, which is to be expected considering the difficulty of collecting travel data. The overall conclusion, however, is that the Truck Inventory and Use Survey and the National Truck Trip Information Survey estimates are reasonably close to each other, whereas "Highway Statistics" estimates are significantly higher. The implication of this finding is that the procedures used by the states and the Federal Highway Administration to generate "Highway Statistics" data lead to artificially and systematically high estimates of travel by large trucks.


Management power influences corporate diversification strategy choice and further corporate sustainable development. Based on a 2007-2013 sample from Shanghai and Shenzhen A share stock market, we test the relationships among management power, diversification and corporate sustainable development deviation from ownership perspective. Empirical results show that diversification strategy leads to sustainable development deviation, but for state owned companies only the combined action of management power and diversification strategy drives sustainable development deviation. Non state owned companies more likely tend to implement diversification strategy; material power management share percentage significantly influences diversification strategy implementation, while for the former it promotes, for the latter it refrains.


The technical conditions for extracting oil from Malana oleifera Chum by ultrasonic were studied. The effect of solvent types, ultrasound temperature, ultrasound extracting time and radio of material to solvent were discussed through single factor and orthogonal experiments. The experimental results show that the optimal solvent was ligarine (60~90 ℃), the optional conditions were as follows: radio of material to solvent 1: 14, reaction time 25 min, ultrasound temperature was 60 ℃. Comparative analysis with Soxhlet, the extration rate of ultrasonic assistant extraction method was higher 6.9% and the ultrasound extraction time was only the 1/17 of Soxhlet extraction


The invention discloses a method for improving the optical performance of an active matrix miniature LED (light-emitting diode) display, and relates to an active matrix miniature LED display manufacturing process. The process method particularly includes the steps: preparing miniature optical structures in one-to-one correspondence to light-emitting pixels on a light-emitting surface of a sapphire substrate of the active matrix miniature LED display; controlling and optimizing the light-emitting direction of the light-emitting pixels.

The miniature optical structure process is simple, key optical parameters such as the contrast and the brightness of the active matrix miniature LED display can be effectively optimized, and the optical performance of the active matrix miniature LED display is improved.


ABSTRACT The collapse of the Soviet Union in 1991 brought profound changes to the borderlands of Kyrgyzstan, Tajikistan and Xinjiang. In eastern Kyrgyzstan and Tajikistan's Gorno-Badakhshan region, present-day weaknesses in territorial control of the post-Soviet state's edges are directly wedded to borderlanders' memories of Soviet-era practices of bordering, perceived locally as both systemically stronger and cognitively more beneficial to local lifeworlds than contemporary 'Chinese penetration'. Across the border in Xinjiang, a formerly distant state has been brought into borderlanders' locales and inscribed into everyday lifeworlds through novel manifestations of the state, which significantly affect cross-border interaction. By comparing how borderlanders on both sides of this frontier themselves choose to characterize border processes between 'their' states in the initial two decades of connections to Xinjiang, I explore how and why Kyrgyz and Tajik/Pamiri borderlanders voice strong opinions about what it is they feel has changed in these administrative-territorial homelands. Based on extensive ethnographic fieldwork on both sides of this frontier, I argue that the gradual bridging of this formerly sealed border has led to neither the development of a new trans-frontier identity nor locally established trans-frontier networks but, instead, reconfirmed borders between China and Central Asia.

Objective: The current research aims to identify the effect of Vestibular rehabilitation exercises on the dizziness-handicap among patients with vertigo. Methods: The research design adopted is a pretest-posttest design. 30 patients with vertigo attending the ENT out Patient Department (OPD) who fulfilled the inclusion criteria were selected randomly by lottery method, 15 were assigned to the study and 15 to the control group respectively. Vestibular rehabilitation exercises which include eye, head, sitting, standing & st walking exercises were demonstrated to the study group patients on 1 consultation using a booklet for 20 minutes along with return demonstration. The patients were reinforced to perform the exercises twice daily for 7 days following which the posttest was carried out on the th 7 day. The control group received routine care. Results : The results showed that in the study group 86.7% had severe level of dizziness-handicap during the pretest which was reduced after practicing vestibular rehabilitation to 13.3% during the posttest, whereas in the control group it was 66.7% and 73.3% who had severe level of dizziness-handicap during the pretest and the posttest respectively. The mean for dizziness handicap for the study group at pretest was 66.3±14.03 and at posttest it was 31.07 ±18.94. The control group showed that at pretest the mean was 61.33±15.24 and at posttest it was 63.87±22.35. This was found to be significant at p=0.0005. Conclusion : The study supported the hypothesis that vestibular rehabilitation exercises had an impact on the dizziness handicap.

: This paper describes a case study whose goal is to present and analyze the main data related to the monitoring of foundation behavior of the Dona Francisca HPP (Hydro Power Plant) gravity dam whose foundation is essentially constituted by sedimentary rocks. The analysis of the foundation behavior was done in terms of deformations recorded during seventeen years of dam operation by multiple rod extensometers. Dona Francisca HPP dam was built in 2000, on the Jacuí River, in the central region of the Rio Grande do Sul State, Brazil. The geological and geotechnical conditions of the foundation are related to the Formação Caturrita rocks, made up mainly of sandstones and intercalated levels of siltstone and argillite. In the first five years of operation there was an intense stabilization process of the foundation rocky massif. After this period, it was verified the occurrence of stabilization at a lower rate. The deformation of the Dona Francisca HPP foundation is higher when compared with other larger dams, such as the Itaipu HPP dam.

AbstractWhen a client approaches a designer with a product need, it is unlikely that his/her need will be expressed very clearly. The client simply might have a problem that needs a solution. This paper will set up a rational/systematic methodology for creative designs, which delivers more customised products with shorter lead times, perfect quality and reliability and at lesser prices. The design method possess the capability to employ the product's overall required function provided by customer, to produce a set of embodiment designs that are capable of obtaining this function.


The text studied the stroke rate and rhythm of men and women kayakers in the world cup competition on the base of defined division of time phase for each stroke. It is found that the time proportion of the pull and air-work phase in the two sides of men kayakers are both 65% to 35%, while the time proportion of the same phase in the right-side of women kayakers is 66% to 34%, and that in the lefl-side is 69% to 31%; the power time proportion in the right-side of men kayakers is 40% and in the left-side is 41 %, while that in the right-side of women kayakers is 39% and in the lefl-side is 41 %. Men kayakers command a better symmetry and consistency between the left and right side in stroke rhythm than women kayakers. Men kayakers increase the stroke rate mainly accompanied with shortening the air-work time proportion while womenkayakers mainly with shortening the pull time proportion.


Segmentation of spinal canals have a great role in many medical fields. Spinal canal is one of the best way used to diagnosis and analysis. Accurate segmentation of the spinal canals in computed tomography (CT) images is an important task in many related studies. Many research and clinical studies require the automatic segmentation of the spines, which is capable of facilitating disease diagnosis, treatment, and statistical analysis/evaluation. For example, the segmentation of the spine provides spatial reference to locate and identify other neighbouring anatomical structures in abdomens and chests, thus contributing to the understanding of the full-body scan essentially. In terms of image registration, the segmented spines provide important features that are helpful to the correct alignment of corresponding anatomical structures across individual subjects. Furthermore, it becomes easier to conduct disease-oriented analysis given the segmented topologies/shapes of the spines. In the meantime, based on the segmentation of the spinal canal, the entire spinal cord can easily be delineated, making it possible to count radiotherapy dosages which are crucial to the normal functions of the nerve tracts


This paper uses actor-network theory (ANT) to study a grassroots' ecological rehabilitation project in a marginalized area of Cape Town. By tracing the stabilization of relations between residents, authorities, plants and green areas, the paper demonstrates how ANT can be enfolded into critical studies of urban environments to rethink agency, empowerment and collective action. It also shows how ANT allows for the study of epistemological and ontological politics inherent to all collective action—here demonstrating how plants participated in giving voice to memories of oppression while undermining expertbased practices that separate Nature and Culture. This repertoire of situating urban political ecologies seeks to stage and make visible ruptures in established ways of knowing urban environments towards a re-distribution of expertise. It contributes to our efforts in developing a situated urban political ecology (SUPE) sensitive to 'ordinary cities' of the global South.


ology of the heart, lung, and circulation. In the heart, factors such as angiotensin II and endothelin-1 have been shown to induce cardiac muscle cell hypertrophy, which may result in heart failure (23). These factors, as well as others, also induce hypertrophy of the vessel wall, which may be important in the development of hypertension and atherosclerosis (2). Growth factors also play essential roles in lung diseases such as pulmonary hypertension, chronic obstructive pulmonary disease, and asthma by increasing the mass of pulmonary artery and airway smooth muscle (12, 14). At the cellular level, growth factors promote hyperplasia, hypertrophy and survival of cardiac muscle, smooth muscle, endothelial, and epithelial cells. Understanding the signal transduction mechanisms utilized by growth factors should help to identify therapeutic targets for various cardiovascular and pulmonary diseases. Regulation by reactive oxygen species (ROS) is a common element in the growth of cardiac and smooth muscle cells (18). One of the earliest demonstrations of a role for ROS in cardiovascular signaling was the observation that ROS are required for angiotensin II-mediated vascular smooth muscle cell hypertrophy (9). Since then, various growth factors have been shown to generate ROS which then serve as signaling molecules in systemic and pulmonary vascular and airway smooth muscle cells. This mechanism has been implicated in the development of systemic and pulmonary hypertension, atherosclerosis, and asthma (10, 11, 22). Furthermore, more recent experiments have provided evidence for a role of ROS in cardiac muscle cells, suggesting a role for redox regulation in the development of cardiac hypertrophy and failure (15, 20). The sources and targets of ROS have been under intense investigation. NAD(P)H oxidases appear to be promising sources of ROS during growth factor signaling (4, 10, 11).


This paper was written at the beginning of November 1999, when the current account deficit in Poland reached 70/0 of GDP and political disputes over the budget and reform of the tax system weakened the zloty within its trading band. This was the right moment to reassess Poland's susceptibility to turbulence in the domestic and international financial markets. The paper is organised as follows. The first section discusses the risk management problems at the macro and micro level. The second section describes the evolution of the exchange rate regime in Poland towards a floating exchange rate. The third section looks at the development of financial markets in Poland and their impact on exchange rate policy.

The present work consists of analyzing from the perspective of political communication 2.0, the electoral campaign of the candidate Guillermo Lasso for the presidency of the Republic of Ecuador in 2017. The study focuses on the use of the social network Facebook, as the new space to design certain campaign strategies. The variables that intervened in the analysis were the Ecuadorian political context of 2017 and the electoral preferences of the citizens, the role played by Lenin Moreno and Cinthia Viteri, as candidates electorally winners, and the relationship between published content and the reinforcement of certain values and ideas of the Ecuadorian electorate. The results obtained showed that both the general perceptions of the electorate over the country situation, and the surveys of intention to vote, are key factors in the delineation of strategies. Likewise, as the campaign develops, the design of spots is accommodated to what the other candidates do or stop doing, applying, and an offensive or defensive strategy. A third result showed that the content is dependent on the values and general ideas that the electorate feels now. And finally, the 2.0 campaigns in Ecuador are neither determinant nor sufficient to achieve electoral objectives, so necessarily must be completed with the traditional campaign.


FITC(fluorescein isothiocyanate) that can be linked to lipase as a fluorescence probe was used to study the relationships among the activity of lipase,conformation,and fluorescence spectrum.The changes of activity and fluorescence spectrum of the labeled and unlabeled lipase were examined under various temperatures,pH and different concentrations of guanidine hydrochloride.The results demonstrated that compared with the unlabeled lipase,the thermal stability of the labeled lipase was improved,and it was completely inactive at 70 ℃.The stability of the labelled lipase at different pH was also increased.The activity of the labeled lipase would decrease under different concentrations of guanidine hydrochloride,and fluorescence spectrum of the labeled lipase could reflect the change of the activity.

Asthma is the most common chronic disease of children and one of the leading causes of preventable hospitalizations in the United States. Ofthe 196,000 hospitalizations that occur each year among the 9 million U.S. children diagnosed with asthma, 15-54% could be prevented, according to a study published in the October issue ofPediatrics. The likelihood of unnecessary hospitalization was twice as likely when family physicians were not consulted, translating to about $161-581 million in charges. The study surveyed parents, primary care physicians and inpatient attending physicians of 230 children who were admitted for asthma to Boston Medical Center, an urban hospital, during a 14month period. Hospitalizations could have also been prevented by improving the education ofpatient and family about the condition; access to medications; follow-up care; and avoidance of disease risk factors, such as smoking. "This is a well-recognized issue," said Dr. David M. Pressel, director of inpatient pediatrics at the Alfred I. duPont Hospital for Children in Wilmington, DE, and aJNMA reviewer. "Awareness and prophylactics" are one of several reasons this rate may decline in the future, leading to fewer preventable hospitalizations. "New medications and new delivery routes are sure to improve treatment and compliance," said Pressel.


The revolution of February 1848 was a major landmark in the history of republicanism in France. During the July Monarchy, republicans were in favour of both universal suffrage and direct popular participation. But during the first months of the new republican regime, these principles collided, putting republicans to the test, bringing forth two conceptions of republicanism -- moderate and democratic-social. After the failure of the June insurrection, the former prevailed. During the drafting of the Constitution, moderate republicanism was defined in opposition to socialism and > unchecked popular participation. Conservatives and moderates promoted the image of the 'universality of citizens' as the real sovereign, acting only through the universal election of legislators and rulers.


The dynamic model of clutch system was set up. Aimed at the contradictory elements of shock intensity and sliding work of clutch in engagement,authors selected the engine rotational speed and the rotational speed of clutch driven side as state variables. In the conditions that shock intensities meet driver comfort,authors took optimal control method with the objective function of sliding work minimum and transformed shock intensities into one of the constraints of optimal control. It avoided the difficulties of the weight factor adjustment in multi-objective optimization. The simulation and test results show that using optimal displacement control can ensure the sliding work minimum in the condition of meeting driver comfort which simplifies the control system and strengthens the control system commonness and transplantation.


Statements here are limited to the traffic signal section of the new Indiana Manual on Uniform Traffic Control Devices, and primarily the changes which have been made with respect to the traffic signal and flashing beacon installation warrants. There are changes with respect to the 1975 Indiana manual and the current federal manual. In revising the warrants for the new manual, an attempt was made to provide criteria which are more responsive to the needs of motorists and pedestrians and less responsive as it states in the manual to the belief of many laymen "that traffic signals provide the solution to all traffic problems at intersections."

THE standing AUTHOR between of the this Ford book,t Founstanding between the Ford F undation and dozens of eager scholars, has been for some time now handing out bucketsful of money for research in government finance. Most of the results have already been published in the Brookings series, and the author himself has previously aired some of the views that appear in his current work. Coming as it does, then, near the tail end of these research efforts, this volume contains little that is new. Anyway, it is for the "interested citizen" and so cannot be expected to break new ground. It certainly was not published for scholars in the field, for, considering the long list of those who read all or parts of the manuscript in draft, virtually everyone in the field saw it before publication. I was one of the few not called on; nor have I ever had my hand in the golden bucket. Indeed, these unusual characteristics explain why the editor of this Journal in the end turned to me as the reviewer. I am very pleased to have been given this opportunity to say nice things about this remarkable and stimulating book (the name is Gurley, Mr. Pechman, at Stanford University). The author first takes up the role of taxes (stabilization, promotion of growth, etc.) and the way in which taxes are legislated. He then moves into the structure and economic effects of federal government taxes, starting


Under the condition without risk-free securities in the security market, to study the problem of shifting movement of portfolio frontier with k(k1)-newly increased securities correlated to the n-former securities is complex. The authors put forward a method of dynamic analysis. Based on the method mentioned above, through shifting analysis, the authors show a serial theorems prove perfect and strict in mathematics, which indicate the features of shifting toward left of portfolio frontier. Finally, the authors make a computer simulation for the conclusions.


We discuss the possibility of engineering a Hamiltonian that can perfectly mirror a state of many excitations stored on a square lattice. In comparison to the well-studied case of a chain, there is potential for a speed-up of information transfer. However, we prove that in a large class of cases, perfect state mirroring on a square lattice is impossible.


The supertransferred hyperfine magnetic field, H STHF , at 111 Cd(← 111 In) on the tetrahedral site of Fe 3 O 4 was measured by means of the time differential perturbed angular correlation (TDPAC) between 85 and 300 K. Each TDPAC spectrum has a well-defined hyperfine frequency component above the Verwey temperature, T V (=120 K), whereas remarkably distributed one below this temperature. The value of H STHF at low temperatures is +121 kOe in average, which shows the covalence in Cd 2+ O 2- bonds is considerably smaller than that in In 3+ –O 2- bonds in spinel type oxides. The apparent distribution of the hyperfine frequencies below T V is qualitatively explained by a distribution of H STHF at 111 Cd due to fluctuation of the relative populations of Fe 3+ and Fe 2+ ions in the neighboring octahedral sites, or a small amount of electric field gradient acting on 111 Cd in addition to H STHF .


study Abstract Objective Oswestry Disability Index is the most commonly used score for assessing spinal disorders disabilities. However, no validated Lebanese version of the index was available till the time of initiation of our study. Our aim is to validate and adapt the Saudi Arabia version of the Oswestry Disability Index among the Lebanese population. Methods: After a cultural adaptation of the Arabic questionnaire, a pilot study was conducted to assess the comprehensibility of the prefinal version. The Lebanese version was tested on 96 patients suffering from low back pain who were assessed by phone call twice within 2 weeks. Internal consistency, test-retest reliability, convergent and discriminant validity were investigated. Result: The Cronbach's alfa for the Oswestry Disability Index was 0.87. Factor analysis revealed the presence of one component with eigenvalue exceeding 1, explaining 68% of the variance. The correlation of the Oswestry Disability Index with the Quebec Back Pain Disability Scale and the Roland–Morris Disability questionnaire was 0.97, 0.95 respectively (P<0.001). The Oswestry Disability Index showed excellent test-retest reliability. Conclusion: The Lebanese Version of the Oswestry Disability Index is reliable and valid tool to assess the functional ability among the Lebanese-speaking population with Low Back Pain.


Since the 1970s, the process of decentralization has spread throughout the world, and today more than 95% of democratic countries are decentralized. Decentralization should lead to a well-organized and more efficient local government. Nevertheless, the empirical results are rather vague. The motivation for this paper is to examine the impact of political and fiscal decentralization on the quality of government in seventeen countries in Central and Eastern Europe for the period 1998 - 2012. The main objective of the paper is to explore whether fiscal decentralization positively influences the quality of government and whether political decentralization reduces its positive influence. An additional contribution of the paper comes from the introduction of a decentralization interaction variable. Our results have shown that fiscal decentralization has a positive impact on governance, while political decentralization was found to be statistically insignificant. Our results also showed that richer countries have higher government quality, that government size increases the level of corruption and decreases government quality, and that in more democratic countries politicians behave more responsibly and accountably, which decreases the level of corruption and increases government quality. We conclude that political decentralization cancels out the positive effects of fiscal decentralization on the quality of government, which can be explained by less developed institutions at the local level in Central and Eastern European countries.


PURPOSE
To determine the relative detectability performance of two x-ray imaging detectors for specific clinical objects and devices.

METHODS
The relative object detectability (ROD) can be defined as the ratio of the integral of the detective quantum efficiency (DQE) of a detector weighted by the square of the Fourier Transform (or frequency spectrum) of the object to the same integral for a second detector. Three different detectors, namely the micro-angiographic fluoroscope (MAF), the solid state x-ray image intensifier (SSXII) and a flat panel detector (FPD), were assessed for their relative performance with respect to the detectability of wires and spheres. The RODs were calculated for three sets of detectors: MAF-FPD, MAF-SSXII and SSXII-FPD, for wires of a fixed length of 20 mm and solid spheres made of different materials (aluminum, titanium and nickel) ranging in diameters from 100 micron to 1.0 mm to simulate endovascular devices.

RESULTS
For the 100-micron diameter, the ROD is 1.4 [2.0] for the MAF-SSXII and SSXII-FPD sets and 1.9 [3.9] for the MAF-FPD for the wire [sphere] indicating superior performance of the MAF over the FPD and SSXII and of the SSXII over the FPD for small sized objects. However, the ROD decreased monotonically as the object diameter increased and showed equivalent performance for wires with diameter over 300 microns and spheres with diameters above 400 microns.

CONCLUSION
The ROD depends upon the physical geometry of the object and is useful in quantifying the relative performance of detectors regarding detectability of specific objects. Because of their higher spatial resolution both the MAF and the SSXII perform better than the FPD for viewing wires with diameters under 300 microns and spheres with diameters under 400 microns; however, the MAF performance is shown to be superior to the SSXII as well.

The effect of the crisis issue in social psychology-focusing on the validity of existing social psychological research methodologies-was examined through an analysis of research trends over the past 15 years. Articles selected from four representative social psychology journals in the 1974-1975, 1979-1980, and 1984-1985 periods were evaluated in terms of (a) type of methodology, (b) subject population (c) use of deception and (d) method of data analysis. Results indicate that, despite the predominance of laboratory experimentation in social psychological research, a significant increase in the use of surveys and questionnaires is noted. In addition, although the predominance of undergraduates as research subjects has shown no change over the 15-year period, deception in research has decreased significantly. Contrary to expectation, the increased availability of linear modeling procedures such as path analysis and multidimensional scaling has not resulted in significant changes in the methods of data analy...


Pandalus bonnieri is a dioecious species and no protandrous hermaphrodites have been seen. The breeding season and incubation period for P. bonnieri are described. The number of eggs laid increases with the size of the female. At 16 mm. carapace length the number of eggs is c. 1000 and at 24 mm. carapace length the number of eggs is c. 4000. The number for a single mm. size group varies roughly by ±10%. Both male and female P. bonnieri become sexually mature at about 18 months, and in the Clyde seldom live beyond 3 years of age. The colour of the eggs in P. bonnieri is sage green, in P. borealis blue green, in P. montagui light emerald green and in P. propinquus fawn. Juvenile P. bonnieri can be separated into males and females by the shape of the pleopods within 4–6 months of hatching.

Abstract Experimental evaluation of the thermal-hydraulic characteristics of helium-cooled divertor concepts is important in developing commercial magnetic fusion energy (MFE). Although experimental studies of a variety of concepts have been performed at the Georgia Institute of Technology (GT) over the last decade, achieving prototypical steady-state incident heat fluxes of 10 MW/m2 remains a major challenge. As an alternative to heating the test section, this work presents an initial assessment of a "reversed heat flux approach" that cools the test modules (instead of heating them) with water to determine the heat transfer coefficients (HTC). This approach was pioneered by the Karlsruhe Institute of Technology (KIT) in their initial studies of the helium-cooled modular divertor with multiple jets (HEMJ). The objectives of this design study are to: 1) determine whether such a reversed heat flux approach can be used to experimentally study the thermal-hydraulic performance of helium-cooled divertor concepts, while minimizing safety and operational issues associated with the extremely high temperatures (>1200°C) reached when testing at prototypical conditions (inlet conditions of 700°C and 10 MPa with an incident heat flux of 10 MW/m2), and 2) determine the design and operational parameters for a small-scale submerged water jet impingement cooling facility suitable for validating these numerical predictions. Numerical simulations were performed to determine the impinging-jet (water) mass flow rates required to remove heat fluxes up to 10 MW/m2 from a single HEMJ module at prototypical conditions (i.e., 700°C and 10 MPa). Initial axisymmetric simulations at water pressures up to 3 MPa suggest that a submerged single-phase impinging water jet at (300 K, 1 MPa) and = 3.5 kg/s can remove heat fluxes as great as 7.5 MW/m2 over a 2 cm diameter area.


This study developed an instructional method for planning education based on a future scenario-making approach for a first-year course at a Japanese university. In environmental policy-making, such as that regarding climate change, energy use, community development, and so on, a multi-collaboration and planning approach was implemented to promote United Nation's Sustainable Development Goals (SDGs). On the other hand, planning education methodology in the Japanese context has not yet been sufficiently discussed. Based on the discussion in the European context and existing research, this paper focuses on a future scenario-making approach as an instructional method in planning education. For the research process, minilectures and group discussions were conducted in two lessons with three different classes, and two surveys, a worksheet analysis, and interviews were conducted with the participants. The results of this study implied the need for the following educational design in planning education: (1) to direct the students' attention to the mitigation of and adaptation to possible negative future events and scenarios, (2) to promote multilateral consideration using self-checking of the students' homework and consideration of future events and scenarios, and (3) to stimulate critical thinking on the basis of (1) and (2).


Objective
To discuss the expressions and clinicopathologic significances of insulin-like growth factor Ⅱ mRNA binding protein 3 (IMP3) in squamous intraepithelial lesion (SIL) and cervical squamous cell carcinoma (CSCC) before and after the therapy of radiation and chemotherapy.

Methods
The expressions of IMP3 in 80 cases of CSCC, 90 cases of SIL (60 cases of HSIL, 30 cases of LSIL) and 30 cases of cervicitis were detected by immunobistochemistry. The relations between IMP3 and clinicopathological cha-racteristics of CSCC were analyzed.

Results
The expression rates of IMP3 in CSCC, HSIL, LSIL and cervicitis were 86.3%(69/80), 78.3%(47/60), 33.3%(10/30) and 0(0/30), and the difference among the four groups was statistically signicant (χ2=87.01, P<0.01). The positive expression rate of IMP3 declined by radiation or chemotherapy (60.0% vs. 85.0%, χ2=5.79, P=0.013). The expression of IMP3 was related with lymph node metastasis (χ2=3.97, P=0.046), differentiated degree (χ2=5.95, P=0.018), clinical stage (χ2=5.82, P=0.016) and invasion depth (χ2=5.73, P=0.017). There was nothing to do with age (χ2=0.11, P=0.745).

Conclusion
IMP3 expresses excessively in CSCC, and is associated with pathological grade and invasion progress. Radio-chemotherapy can reduce the expression of IMP3.

[Objective] To explore the relationship of chemotherapy sensitivity and gene expression in 18 human cancer cell lines. [Methods] MTT method was used to detect the sensitivity on Adriamycin(ADM), Cisplatinum(DDP), Mitomycin C(MMC), Fluorouracilum(5-Fu), Carmustine (BCNU) in cancer cell lines. Multidrug resistance genes including P-glycoprotein (P-gp), Glutsthione-s-transferases-π (GST-π), Lung resistance protein (LRP), Multidrug resistance related protein (MRP), MGMT and apoptosis regulation genes Fas, bcl-2, p53 and p16 were examined by flow cytometry (FCM). [Results] The chemotherapy sensitivity was obviously divergent in different cancer cell lines. The correlation analysis revealed that there were negative correlations between the sensitivity on DDP in cell lines and the expression of p53 protein, the P value was 0.041. There were no correlations among the sensitivity on other drugs and expression of other genes (P 0.05). [Conclusions] The sensitivity on DDP had correlation with the the expression of p53 in cancer cell lines.


The heart clinic in Huddinge is a part of the Karolinska University Hospital, which is among the largest hospitals in Europe. Since the clinic receives over 3000 patients annually, substantial amounts of products are consumed. This requires the clinic to have an overview of inventory levels, so that restocking orders can be placed whenever inventory levels fall below certain limits. Currently, they are determined by manual stocktaking, which is timeconsuming. The purpose of this project was to suggest a system that automates inventory management, so that the staff can be notified whenever inventory levels drop below predefined minimum levels. This has been done by investigating companies that either offer or use inventory management systems. It resulted in an analysis of SpaceTrax, a documented solution for inventory management in healthcare. SpaceTrax, which is used in a hospital in Sweden, fulfills the heart clinic's functional needs and can lead to economic savings. Due to shortcomings of SpaceTrax, an alternative, self-designed system was investigated. After comparing the self-designed system with SpaceTrax, SpaceTrax was suggested as a solution.

The 2D C/SiC plate seeded with the defects was manufactured by the chemical vapor infiltration(CVI) process.The C/SiC plate with defects was examined using three Nondestructive Testing(NDT) technologies: thermography,X-ray radiography and computed tomography.The flexural properties of the sample with the defect were also investigated.The results show that X-ray radiographic technology is applicable to examine the defects with different densities,thermographic technology can be applicable to test the defects with poor thermal diffusivity such as the pores and delaminations,and industrial computed tomographic technology is applicable to detect the exact localization,in particular the visualization of the depth and thickness of the defects.It is found that the 2D C/SiC samples can easily crack and delaminate in the interface between matrix and defect under loading.With increasing the defect length,the flexural strength of the samples and the crack propagation energy decrease.


In a gas-liquid reactor agitated by an impeller, the local forces vary depending on the two-phase dispersion pattern. At a given location, the pressure fluctuation must be related to the bubble dispersion pattern. This provides a direct means of flow pattern detection in situations where direct visaul observation is impossible or impractical. In this paper, pressure fluctuations were measured at various points in the water model of an aluminium melt treatment unit. The pressure signals obtained were analyzed and information extracted and related to the flow patterns observed.


This research proposed and enhanced a statistically reliable paradigm for determining the impacts of the role of digital servitization (DS) as a potential facilitator of sustainable and smart service innovation ecosystem (SSSIE) establishment and sustainability-oriented organizational performance (SOOP) improvement. Additionally, this research aimed to cast light on the role of digital leadership (DL) as a moderator of the hypothesized model. Structural equation modeling and multigroup analysis (MGA) were employed to process and analyze the data procured from a cross-sectional convenience sample of 412 respondents representing various public service sector organizations (PSSOs). The statistical outcomes corroborated that DS was positively and significantly correlated to SSSIE establishment, and at the same time, SOOP was significantly intensified by DS and SSSIE. Next, the nexus between DS and SOOP was enhanced when SSSIE was operationalized. Lastly, the MGA analysis confirmed that all of the coefficients in the proposed model were statistically significantly different under the moderating effect of DL. These obtained findings could bring numerous valuable in-depth insights for practitioners and policymakers in digital initiatives management and governance.


In the article we consider the relationship of traditional provisions of basic logical concepts and confront them with new and modern approaches to the same concepts. Logic is characterized in different ways when it is associated with syllogistics (referential – semantical model of logic) or with symbolic logic (inferential – syntactical model of logic). This is not only a difference in the logical calculation of (1) concepts, (2) statements, and (3) predicates, but this difference also appears in the treatment of the calculative abilities of logical forms, the ontological-referential status of conceptual content and the inferential-categorical status of logical forms. The basic markers or basic ideas that separate ontologically oriented logic from categorically oriented logic are the (1) concept of truth, the (2) concept of meaning, the (3) concept of identity, and the (4) concept of predication. Here, this differences are explicitly demonstrated by the introduction of differential terminology. From this differential methodology follows a new set of characterizations of logic.


AIM
To study beta2-GP-I-dependent binding of phospholipid antibodies (PAb) to phospholipids and this process participation in pathogenesis of antiphospholipid syndrome (APS).

MATERIALS AND METHODS
IgG-fractions and sera from 20 patients with APS. Cofactor activity of beta2-GP-I isolated from serum of healthy donors was examined with modified immunoassay.

RESULTS
Contrary to donor IgG, binding of IgG fractions isolated from sera of APS patients with cardiolipin grows dose-dependently in the presence of beta2-GP-I. Cofactor activity of beta2-GP-I is confirmed in the study of sera of APS patients. Sera containing beta2-GP-I-dependent antibodies to cardiolipin (aCL), unlike aCL-negative sera, react with solid-phase immobilized beta2-GP-I.

CONCLUSION
It is confirmed that beta2-GP-I participates in interaction of PAb with cardiolipin. Pathogenetic implication of beta2-GP-I-dependent PAb for onset of APS is discussed.

Speed of vehicular travel is continually reducing; Reasons being increasing vehicle population rendering the road capacity inadequate. The achievable speeds in vehicles are not attained because of traffic congestion, rendering automotive developments ineffective. Vehicles emit CO2, which increases during low speeds and idling resulting in denser CO2 cloud, thereby contributing to global warming. Congestion is one of the fundamental reasons for accidents. This makes vehicular traffic congestion a confronting facet to growing economy and pollution and justifiably deserves eminent priority. This paper studies the present congestion mitigating sensor technologies and the parameters measured. It describes "Parameters of Significance (POS)" for accurate measurement and defines a roadmap of sensor technology to realize accurate measurement and monitoring. A detailed comparison of sensor technology to manage the POS is carried out with a view to realize at affordable cost, with minimal efforts and achieve large foot print. The proposed sensors collate the parameters and are subjected to decision making systems for enabling vehicular traffic decongestion strategies. The key technologies are sensor networks and parameter collating methodologies. Summarizing, the paper evolves POS and their monitoring tools with an endeavor is to arrive at holistic solution and lay-down scope for future work. Language: en


Recent research has provided important principles to follow in successfully revegetating disturbed lands in arid climates. Sustainable revegetation needs to be accomplished within the confines of the existing ecosystem of the area. Revegetation planning, revegetation implementation, and evaluation and monitoring should be considered for each revegetation project. Planning includes conducting a site assessment, establishing goals and standards, determining site preparation requirements, selecting species, selecting revegetation techniques, selecting conservation and water management treatments, determining timing, and evaluating costs. Revegetation implementation begins with the selection of an on-site manager who will monitor adherence to the revegetation plan, conduct prejob meetings, and ensure revegetation is implemented as planned. Project evaluation and long-term management includes conducting on-site inspections, evaluating success, and implementing modification where necessary. Successful revegetation projects completed within the Great Basin and Mojave Desert ecoregions are presented. Seeding and transplanting prove to be successful in Great Basin ecoregion. Irrigation was used with highly predictable success in transition zone between Great Basin and Mojave Desert ecoregions. Seed pretreatment, irrigation, and various mulches show promise for successful revegetation in the drier Mojave Desert ecoregion.


The interplanar surface relaxations of seven face-centered and nine body-centered cubic metals are calculated for their three low index surfaces. In f.c.c. lattices the relaxation for the three surfaces is in the order (110) > (100) > (111) whereas in b.c.c. lattices the order is (111) > (100) > (110). In general the relaxation is greater for b.c.c. metals than for f.c.c. Comparing different metals of the same structure, it is found that the relaxation is closely related to a non-dimensional parameter , where α and r0 are parameters of the Morse potential.


Vitamin D deficiency is a common problem among Egyptian females across all age groups, for whom contributing factors include inadequate sun exposure possibly related to cultural/social factors, and insufficient dietary calcium, wearing a sunscreen reduces vitamin D synthesis in the skin by more than 95%. Not only environmental factors, such as sun exposure and nutrition, but also genetic and possibly also epigenetic factors are determinants of serum 25(OH) D.

 We sought to determine the frequency of occurrence of vit D deficiency in Egyptian adolescent females aged 10-18 years in Cairo.

 Study was conducted on 90 healthy adult females aged (10-18) years and classified them into: Sufficient group: with vitamin D level >30ng/ml, (40%) of participants. Mild deficient group: with vitamin D level between 21-29ng/ml (14.44%) of participants. Moderate deficient group: with vitamin D level between 10-20ng/ml (11.11%) of participants. Severe deficient group: with vitamin D level <10ng/ml (34.44%) of participants.

 Our study showed a high prevalence of low vitamin D level among healthy adolescent females aged (10-18) years old. There were a significant difference On comparing vitamin D status groups as regard vitamin D rich food intake, duration of sun exposure and height for age (p < 0.001), (p < 0.001) and (p = 0.012) respectively. There were significant difference on comparing vit D status groups with s.Ca, PTH and Alk.Ph (p < 0.001).

 Vitamin D deficiency became endemic in Egypt. Large-scale studies are needed to properly evaluate the size of the problem.

For isotactic poly(methyl methacrylate), molecular mechanics energy calculations were carried out on several double-stranded helix oligomer models for analyzing the energetical stability of the polymer double-stranded helix determined by X-ray analysis. The calculation results indicate that the double-stranded-helix structures can exist as stable double-stranded helices by the favorable intertwined interactions of the van der Waals interactions for the large oligomers (n≥10; n is the number of monomers in the oligomer). Moreover, the calculated double-stranded helix structure by the energy minimization method is in good agreement with the observed structure by X-ray analysis.


ABSTRACT The genesis of a 30 billion dollar a year electrophotographic industry can be traced to the sole effort of Chester Carlson who demonstrated in 1938 that dry images could be produced by a new process involving the attraction of charged pigmented particles to an electrostatic image formed on a photoconducting film. Carlson's invention, a particular form of electrophotography, is known as xerography. Most electrophotographic processes are based on the deposition of charged particles in either an air or liquid medium. The marking particles are usually pigments dispersed in a polymer matrix. The various electrophotographic processes are critically dependent on the electrical and mechanical properties of particles and dispersions. We examine the role of particles and dispersions in electrophotographic processes in general, and xerographic processes in particular.


Cross‐sectional TEM analysis is one of the most important techniques to characterize microstructures of films. However, the complex process, low efficiency, and low success rate of specimen preparation limit its application. This paper analyzed the main causes of low success rate and proposed an improved method for specimen preparation of films deposited on metallic substrates. This method consisting of twin‐jet electropolishing and one‐sided rocking ion milling is high in efficiency and success rate. Microsc. Res. Tech. 79:276–279, 2016. © 2016 Wiley Periodicals, Inc.


Over 500,000 Americans are influenced each year by fake news, which has an impact on society. Researchers are examining data on fake news identification and looking into machine learning models for a quicker and more accurate categorization as part of their investigation of false news detection techniques. This study's main objective is to examine, contrast, and evaluate how well three distinct machine learning algorithms do at spotting fake news. Decision tree, Random forest, and logistic regression are the machine learning algorithms. There are 21418 datasets available for real news, compared to 23503 for fake news. The open-source Kaggle dataset, which was selected for the project, served as the source of both datasets. The results of the construction and comparison showed that the decision tree model did the best forecasting with a maximum accuracy of 99.64% and the random forest model performed well with an accuracy of 98.89%. However, the logistic regression model did well in this assignment with an accuracy of 98.88%. Using these models has the critical goal of improving the news verification system's accuracy and dependability. Keyword: Fake news, Verification System, Machine Learning Model.
