INSTANT is the INL's next generation neutron transport solver to support high-fidelity multi-physics reactor simulation INSTANT is in continuous development to extend its capability Code is designed to take full advantage of middle to large cluster (10-1000 processors) Code is designed to focus on method adaptation while also mesh adaptation will be possible. It utilizes the most modern computing techniques to generate a neutronics tool of full-core transport calculations for reactor analysis and design. It can perform calculations on unstructured 2D/3D triangular, hexagonal and Cartesian geometries. Calculations can be easily extended to more geometries because of the independent mesh framework coded with the model Fortran. This code has a multigroup solver with thermal rebalance and Chebyshev acceleration. It employs second-order PN and Hybrid Finite Element method (PNHFEM) discretization scheme. Three different in-group solvers - preconditioned Conjugate Gradient (CG) method, preconditioned Generalized Minimal Residual Method (GMRES) and Red-Black iteration - have been implemented and parallelized with the spatial domain decomposition in the code. The input is managed with extensible markup language (XML) format. 3D variables including the flux distributions are outputted into VTK files, which can be visualized by tools such as VisIt and ParaView. An extension of the code namedmore » INSTANTHPS provides the capability to perform 3D heterogeneous transport calculations within fuel pins.

Abstract The evolution of the international transfer market continues to demonstrate the vibrancy and attractiveness of the UEFA clubs and leagues. This explains why African players are attracted to a professional career in European clubs. Based on two decades of data collection (1994–2014), this article analyses the evolution of African players' careers with the case of Ghanaian home-grown players' mobility in the international transfer market. The players' career dynamic is based on a combination of transfer values and their ages. We relied on data from transfer records, information on the football labour market and the product life cycle theory to identify African players' career dynamics. This allows us to determine the four cycles in players' careers: domestic development, international career development, maturity and the decline which corresponds to the nonlinear evolution of their transfer values. The results supported to construct the African footballers' 'Careers' Path Model Dynamics (CPMD)' of professional players.


Objective: To evaluate follow-up compliance of patients with CKD stage 3-5 in the nutrition clinic, and explore its related factors. Methods: The data of 468 patients with CKD stage 3-5 who got nutrition files created from January 2007 to December 2012 were retrospectively analyzed. Logistic regression was used to analyze the influencing factors of follow-up compliance. Patients' demographic data, family support, baseline renal function and serum albumin level were all included in the analysis. At the same time, the subjective reasons of poor adherence were explored. Results: There were 213 cases that still got follow-up at present. Their data were included in this analysis. Their average follow-up time was(26.85±22.37) months, average age(47.16±13.79), 64 cases(30.05%) had regular follow-up. The Logistic regression analysis showed that family support(OR=2.448, P0.001), e GFR(OR=0.638, P=0.038), Alb(OR=0.932, P=0.043) were influencing factors of follow-up compliance. Family support had positive correlation with the follow-up compliance. While e GFR and Alb level had negative correlation with the compliance. Eight themes were obtained after interviewing with the patients with poor compliance, and it was found that those patients had not recognized the importance of long-term nutrition management yet. Conclusion: The follow-up compliances of patients with CKD stage 3-5 in the nutrition clinic need to be improved. Nursing education of patient's family should be strengthened to increase their consciousness of the diet nutrition monitoring and management. Hierarchical management according to patients' kidney function and nutrition level should be implemented to prevent malnutrition effectively.


Mathematics is the backbone of most fields of computer science, especially image processing. Linear algebra achieves important results in image processing by the use of algebraic decomposition methods in different trends, the most important of which are the watermarking techniques. The main aim of this paper is to optimize the zero watermarking technique depending on an optimization algorithm and a decomposition method as an algebraic transformation without using any other popular transform such as discrete wavelet transform (DWT), discrete cosine transform (DCT), and lifting wavelet transform LWT. The singular value decomposition (SVD) is regarded as one of the algebraic methods used in this paper to transform the 8*8 blocks of the original grayscale image into the frequency domain to extract the features of the original image. The singular values in the position (1,1) of each diagonal matrix for each block are chosen to generate the feature bits matrix (master-share) to obtain the final zero-secret of the watermark image. The genetic algorithm (GA) is performed on zero-secret to obtain the zero secret sequence that represents the optimal feature bits matrix (master-share) to optimize the zero watermarking technique. The experimental results show that the technique is worked successfully and is robust and resistant against the attacks adopted depending on the test of the robustness and imperceptibility values.


Python is a popular programming language known for its flexibility, usability, readability, and focus on developer productivity. The quantum software community has adopted Python on a number of large-scale efforts due to these characteristics, as well as the remote nature of near-term quantum processors. The use of Python has enabled quick prototyping for quantum code that directly benefits pertinent research and development efforts in quantum scientific computing. However, this rapid prototyping ability comes at the cost of future performant integration for tightly coupled CPU-QPU architectures with fast-feedback. Here, we present a language extension to Python that enables heterogeneous quantum-classical computing via a robust C++ infrastructure for quantum just-in-time (QJIT) compilation. Our work builds off the QCOR C++ language extension and compiler infrastructure to enable a single-source, quantum hardware-agnostic approach to quantum-classical computing that retains the performance required for tightly coupled CPU-QPU compute models. We detail this Python extension, its programming model and underlying software architecture, and provide a robust set of examples to demonstrate the utility of our approach.


We propose that many features of the cusp and low-latitude boundary layer (LLBL) observed near noon MLT can be explained by interpreting the LLBL as being on open lines with an inner boundary at the separatrix between open and closed magnetic field lines. This interpretation places the poleward boundary of the LLBL and equatorward boundary of the cusp along the field line that bifurcates at the cusp neutral point. The interpretation accounts for the abrupt boundary of magnetosheath particles at the inner edge of the LLBL, a feature that is inconsistent with LLBL formation by diffusion onto closed field lines, and for the distribution of magnetosheath particles appearing more as one continuous region than as two distinct regions across the noon cusp/LLBL boundary. Furthermore, we can explain the existence of energetic radiation belt electrons and protons with differing pitch angle distributions within the LLBL and their abrupt cutoff at the poleward boundary of the LLBL. By modeling the LLBL and cusp region quantitatively, we can account for a hemispherical difference in the location of the equatorial boundary of the cusp that is observed to be dependent on the dipole tilt angle but not on the interplanetary magnetic field (IMF) x component. We also find important variations and hemispherical differences in that the size of the LLBL that should depend strongly upon the x component of the IMF. This prediction is observationally testable. Finally, we find that when the IMF is strongly northward, the LLBL may include a narrow region adjacent to the magnetopause where field lines are detached (i.e., have both ends connected to the IMF).


Forty five single crosses were derived from crossing of ten horticulturally superior, optimally diverse and nearly homozygous lines of okra (Abelmoschus esculentus (L.) Moench) namely; P1(IC282248), P2(IC27826-A), P3(IC29119-B), P4(IC31398-A), P5(IC45732), P6(IC89819), P7(IC89976), P8(IC90107), P9(IC99716) and P10(IC111443) in half diallel fashion during summer, 2009 to develop 45 F1s. All 45 F1s along with their 10 counterpart parental lines were evaluated in a randomized block design with three replications over three seasons (early, mid and late kharif, 2009) at the Vegetable Research Station, Rajendranagar, India. Combining ability analysis revealed the preponderance of non-additive gene action involved in the inheritance of plant height, internodal length, days to fifty percent flowering, first flowering node, first fruiting node, fruit length, fruit weight, total number of fruits per plant, number of marketable fruits per plant, total yield per plant, marketable yield per plant and yellow vein mosaic virus infestation on fruits and plants and additive gene action involved in the inheritance of number of branches per plant and fruit and shoot borer infestation on fruits and shoots. The parental lines P5(IC45732) and P7(IC89976) were superior general combiners for total and marketable yield per plant and other traits, which could be exploited for developing prolific and precocious pure line varieties of okra. The crosses C23(IC29119-B x IC99716), C17(IC27826-A x IC111443), C42(IC89976 x IC111443) and C43(IC90107 x IC111443) were superior specific combiners for total and marketable yield per plant with the potential of being commercially exploited for the production of F1 hybrids. The cross combinations C17 (IC27826-A x IC111443) and C42(IC89976 x IC111443) having one or both of the parents with positively significant general combining ability effects for total and marketable yield per plant could be utilized in recombination breeding with single plant selection in the passing generations to capitalize additive gene action to develop lines or varieties with higher total and marketable yield per plant in okra.


In this paper we prove the following general theorem. Let (E, ‖ · ‖E) be a uniformly convex Banach space, and let C be a bounded, closed and convex subset of E. Assume that C has nonempty interior and is locally uniformly rotund. Let F be a commutative nonexpansive semigroup acting on C. If F has no fixed point in the interior of C, then there exists a unique point x̃ on the boundary of C such that each orbit of F converges in norm to x̃. We also establish analogous results for semigroups and mappings which are asymptotically nonexpansive in the intermediate sense.


We examined parenting of adolescents with Consensual Qualitative Research analyses of five 90-minute focus groups with 45 Mexican immigrant parents residing in a high-crime and low-income neighborhood. Parents identified gangs as their major challenge in parenting. Relatedly, they endorsed control-oriented practices to ensure the safety of their adolescents. In addition, parents used practices that aimed to build strong, trusting relationships with their adolescents. The co-occurrence of parenting strategies that promote strong parent-adolescent bonds along with strict monitoring highlights the need to conceptualize parenting with both controlling as well as supportive dimensions. Moreover, the parents' narratives pertaining to the dangers in their neighborhood suggest that interventions for Latino families should be not only consistent with their cultural heritage, but also grounded in the families' local neighborhood contexts.


PurposeBoth high reliability theory (HRT) and "new school" supply chain resilience (SCR) promote a multi-layered, adaptable, transformational, and holistic perspective on organizing and managing. The authors explore whether, and if so how, HRT offer fresh perspectives on the SCR challenges experienced during COVID-19 and on organizing for future resilience.Design/methodology/approachAddressing SCR at the interorganizational network level, and blending theory synthesis and case study research, the authors assess if and how HRN constructs and practices can guide analysis of SCR in dynamic, complex networks, and help shape development pathways towards organizing for resilience. Findings draw on thick description and iterative coding of data (58 interviews and 200+ documents) on the buyer network responsible for managing the supply of critical medical products in the Netherlands.FindingsHRT highlights the interconnectedness of challenges encountered during COVID-19 and helps design future resilience through three lessons. Organizing for SCR requires (1) both anticipation and containment strategies, (2) stable working relationships characterized by trust, and (3) a clear basis of command underpinned by experience-based legitimacy.Originality/valueDistinctive from SCR, which views crises as "black swans", HRT organizes around everyday consideration of the risk of failure. Taking a buyer network perspective, the authors move beyond the buyer-supplier network focus in SCR. The authors contend that emphasis on measures such as supplier base management, stockpiling, and domestic production are essential but not sufficient. Rather, HRT implies that deep structural and social ties within the buyer network should also be emphasized.

Facebook, Twitter, and Instagram are the most often and most widely used social-media sites, especially in Indonesia. The number of social-media users is increasing every year, accompanied by increased risks. One of those risks is to the security and privacy of users, as shown by the user-data leak experienced by Facebook in 2018. These issues led the authors to conduct research relating to the influence of privacy concerns, trust, and user awareness on the readiness to share personal information via social-media sites. A research model was developed based on several hypotheses. The research model was confirmed, and experiment was conducted from 340 social-media users through a questionnaire-based online survey over a period of 2 months. To confirm the structural model used in this research, reliability and validity analyses were performed. Structural equation model (SEM) analysis was used to detect relationships among constructs in the research model. The results of this research show that user awareness, trust, and privacy concerns have a positive and significant effect on sharing personal data on social media. Then we discussed the implications of our results for policy-making, practice, and future research.


The main work of this paper is to build a simulation platform for studying the anti-electromagnetic interference problem of navigation receiver. The simulation platform includes multi-array antenna simulation module, direction of arrival (DOA) estimation algorithm, adaptive spatial filtering algorithm module and interface file reading and writing module. Aiming at the problem that the satellite signal is submerged in the interference and causing subsequent tracking and solving failure, the mode space conversion method is adopted to make the ESPRIT algorithm applicable to the uniform circular array(UCA), realizing the spatial signal two-dimensional DOA estimation, and adopting the linear constrained minimum variance criterion (LCMV) performs adaptive spatial filtering to achieve anti-jamming purposes. The simulation platform can flexibly set parameters such as the number of array elements, satellite signals and interference, which greatly facilitates the research on the anti-electromagnetic interference problem of the navigation receiver.


Abstract This article offers the first study of the Cahiers d'Histoire Mondiale, the Journal of World History published under the auspices of UNESCO from 1953 to 1972 as a by-product of the 'History of mankind' project. Drawing on material in the UNESCO archives, it delves into what Lucien Febvre, the first editor of the Cahiers, called his 'kitchen', in order to understand world history as a practice. Data on author origin and article subject matter point to the journal's mitigated success in overcoming Eurocentrism. The article ultimately contends that the Cahiers was at once a laboratory that experimented with new forms of relational history, and a forum where the very nature of world history was discussed by scholars from around the world (mainly from the West, but also from the East and the South). It suggests that today's epistemological discussion on global history might benefit from the reflection offered by this now largely forgotten experiment.


Antimicrobial activity of the decoction and spirituous extraction of the leaves, flowers of the intact plant and callus of the leaf and flower origin of the lilac kind «M. Sholokhov» and antioxidant activity of the extracts of these objects has been investigated. Decoctions of the leaves, flowers of the intact plant and callus of the leaf and flower origin of the lilac don't show antimicrobial action in relation to Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus.

In reconstruction based super-resolution, it is an important issue to up-sample and to merge the high-frequency information contained in low-resolution images efficiently and without artifact. The conventional up-sampling methods, which used for registering low-resolution data to high-resolution grid, have the difference between them and ideal upsampling in observation modeling. In this paper, we analyze the difference and propose a new up-sampling and merging method which is able to incorporate low-resolution images without loss of the high frequency data and minimizes the artifact caused by data insufficiency. By this method, regions that the registered high frequency data do not cover are naturally regularized without using complex regularizers. The experimental results show that the choice of up-sampling significantly affects the quality of resulting images and the proposed up-sampling method gives better results compared with conventional simple up-sampling method.


The effects of diltiazem and some of its metabolites on the cardiovascular system were studied in anesthetized dogs and in blood-perfused canine papillary muscles. The metabolites included N-desmethyldiltiazem (MA) a newly discovered major metabolite: desacetyldiltiazem (M1): desacetyl MA (M2): O-desmethyl M1 (M4): and O-desmethyl M. (M). In the anesthetized dog. diltiazem and its metabolites produced a dose-dependent increase in coronals blood How. decreases in blood pressure and heart rate, and an increase in left ventricular dP dtmax. The ranking of coronary-vasodilating activity of diltiazem and its metabolites, in decreasing order, was diltiazem. M1. MA. M2. M4. and M. The effects of the metabolites were more selective for coronary vasodilation than for hypotension, but their selectivities were less than that of diltiazem. Coronals vasodilation and hypotension with diltiazem and M were of longer duration than those with their corresponding desacetyl metabolites. By close arterial administration to the blood-perfused canine papillary muscle preparation, diltia/em and its metabolites also produced coronary -vasodilating actions, whereas the negative inotropic actions were very weak. The present study revealed that the cardiovascular properties of some of diltia/em's metabolites arc qualilativeh the same as those of diltiazem. but the activity of diltiazem is the most potent, and MA is less active than M1.


Today, Bagnold's theory is still applied to gravity-driven flows under the assumption of uniform sediment concentration. This study presents findings of flume experiments conducted to investigate the velocity and concentration distributions within the debris body by using high-resolution images. The analysis has shown that the concentration and mobility of grains vary along the depth. A linear law to interpret the grains concentration distribution, starting from the knowledge of the packing concentration and of the surface concentration, Cs, has been identified. By considering such a law, modified expressions of the Bagnold's number and the velocity in stony-type debris flows are also presented. By using these expressions, three regimes of motion have been identified along the depth, and the velocity profile within the debris body is determined as a function of the parameter Cs. It has been verified that the velocity profiles estimated by using the modified equation compare well (mean square error less than 0.1) with the literature's measured profiles when Cs is correctly measured or estimated. Results of cutting tests, conducted for a sample of the used material, have also allowed us to verify that Cs could be determined as a function of the static friction angle of the material.

Background With the rising demand for the use and application of modern immersive technologies, recent studies have investigated the user experience of augmented reality (AR) and virtual reality (VR) for video game purposes. Despite AR's and VR's pervasiveness in the video game industry, research studies into the effects of mixed reality (MR) on video game experience are scarce. This study examined the impact of MR on video game satisfaction, enjoyment, and user performance of first-time users. Method Participants played the same strategy video game across two platforms, an MR headset and a mobile device. A short version of the Game User Experience Satisfaction Scale (GUESS-18) and the Enjoyment scale (ENJOY) were used to measure satisfaction and enjoyment. Results Results demonstrated that MR provided greater overall satisfaction, engrossment, creativity, and personal gratification. In addition, results revealed higher overall enjoyment, challenge/improvement, and engagement in the MR condition. Interestingly, participants performed better with the mobile version. No statistical differences were found between the conditions regarding the GUESS's usability, audio aesthetics, visual aesthetics, and the ENJOY's pleasure and competence. Conclusion The study provides insight into how MR influences satisfaction and enjoyment for video games. Playing a video game in mixed reality has the potential to enhance the user experience of game players despite the possibility of simulator sickness and worse performance than traditional mobile environments. Features of the gameplay that enhanced as well as diminished video game experience are discussed.


Visiting Haiti at the beginning of this decade, one could see that paradise paintings were popular. Every art dealer major or minor had a stock of them. Street vendors hawked them by the dozens to tourists, and in the Centre d'Art in Port-au-Prince one whole room was filled to capacity with racks and bins of them. They were as easy to find as a Madonna in Rome, probably with roots as deep. The notion of Eden, a condition of real or imagined past, and the notion of utopia, a hope for the future, are drawn together in the present of certain of these Haitian works. Their mood is not unlike that of the stoic landscapes of Nicholas Poussin, where idyllic vegetation and peaceful skies surround tragic events, or harbor half-concealed, endangering evil. For a scant decade and a half after the 1804 Declaration of Haitian Independence, Henry Christophe, a general during the war who became ruler of the northern portion of Haiti, attempted to direct the creation of a New Order in the World. His efforts and ideas were not unlike those that generated the many planned communities in England and the United States in the nineteenth century. His conception included a comprehensive and detailed legal code; structures of governance; provisions for education, including art, music academies, and libraries; establishment of a religion and of religious toleration; support from agriculture and commerce; and a defense system to protect the new order from fresh incursions of the old in the form of Napoleon's army. As had other utopian schemers, he planned for these social structures to be housed in suitably stately buildings, laid out in an appropriate spatial order. Numa Desroches depicted the methodical array of walls and stairs and windows of Christophe's Palais Sans Souci in the years of its new splendor. The remains of the most stunning and dominating of these edifices of the New Order outlasted the short-lived kingdom, in time becoming emblematic of a country that was Black and selfgoverning. Jacques-Richard Chery's painting of 1958 commemorates the building of the Citadel.

institutions is explored by a Rand Corporation research team under the general subject of &dquo;The Social Effects of Communication Technology.&dquo; In revising the earlier edition of this book, the editors have renewed an impressive percentage of its content-retaining the real classics in communication research during its early years, but replacing aging inquiry with up-to-date research reports of special interest to educational psychologists and administrators as well as specialists in the mass media and social psychology. The effects of television and other mass media violence upon learning, of media preference upon voting, of media use upon family planning, and of media action upon the success or failure of public information campaigns are all examined thoroughly, with attempts made to reconcile or explain apparent discrepancies in the findings of related research projects. The research reviewed includes both the erection of theoretical

Abstract Introduction  Intramedullary spinal epidermoid cysts have a reported incidence of less than 1% of intramedullary spinal cord tumors; and out of these, intramedullary epidermoid lesions within the cervical spinal cord are even rarer. Here, we present the case of an adult patient with an infected intramedullary epidermoid cyst, identified on magnetic resonance imaging (MRI) at the C7–D1 level that was successfully excised without any worsening of neurological status. Case Presentation A 23-year-old female patient presented with history of moderate degree intermittent fever followed by gradually progressive right-sided weakness. She had paresthesia below C5 dermatome on the right side. On close inspection of
the back, a tiny sinus opening was noted at the D2 level near the midline. MRI of the spine showed an intramedullary lesion at the C6–D1 level with the tract connecting to the subcutaneous lesion. Somatosensory evoked potential (SSEP) monitoring was done during the surgery with near total excision of the lesion. Conclusion Even though the location is rare, a differential diagnosis of the epidermoid should always be considered. A tiny dermal sinus opening helped us in proper diagnosis, along with surgical excision, by providing us a direct path to the intramedullary lesion. An early diagnosis and treatment with neurophysiological monitoring helped us in the maximum safe resection of the lesion without developing any new deficit.


In this paper, multi-staging (MLADM) and pade appro ximation are employed as tools to improve the perfo rmance of the Laplace Adomian Decomposition Method (LADM) scheme on the Rabinovich-Fabrikant system for the n onchaotic and chaotic case. We observe that the MLADM solutions were consistent with the fourth order Ru nge-Kutta (RK4) solutions and that pade approximation does no t sufficiently improve the LADM or the MLADM soluti ons for the chaotic and non-chaotic Rabinovich-Fabrikant sy stem.


In this study, the singular boundary method (SBM) is employed for the simulation of nonlinear Klein-Gordon equation with initial and Dirichlet-type boundary conditions. The θ-weighted and Houbolt finite difference method is used to discretize the time derivatives. Then the original equations are split into a system of partial differential equations. A splitting scheme is applied to split the solution of the inhomogeneous governing equation into homogeneous solution and particular solution. To solve this system, the method of particular solution in combination with the singular boundary method is used for particular solution and homogeneous solution, respectively. Finally, several numerical examples are provided and compared with the exact analytical solutions to show the accuracy and efficiency of method in comparison with other existing methods.


A comparison between current and flux control in magnetic bearing systems is made. The system dynamics were modeled in two different forms. In the first form, the magnetic force and electric circuit equations were expressed in terms of airgap flux and gap displacement. In the second form both equations were expressed in terms of coil current and gap displacement. A controller was designed using the Q-parameterization theory and CONSOLE [14] (an optimization software developed at the University of Maryland) to stabilize the system which without control is unstable in nature. The time and frequency responses for both models were compared. The comparison is based on the same values of the respective controller Q-parameters. The results show that magnetic bearing systems can have better performance if they are modeled using airgap flux.


This paper is about generating security tests from the Common Criteria expression of a security policy, in addition to functional tests previously generated by a model-based testing approach. The method that we present re-uses the functional model and the concretization layer developed for the functional testing, and relies on an additional security policy model. We discuss how to produce the security policy model from a Common Criteria security target. We propose to compute the tests by using some test purposes as guides for the tests to be extracted from the models. We see a test purpose as the combination of a security property and a test need issued from the know-how of a security engineer. We propose a language based on regular expressions for the expression of such test purposes. We illustrate our approach by means of the IAS1 case study, a smart card application dedicated to the operations of Identification, Authentication and electronic Signature.


The stimulation of astaxanthin synthesis in Haematococcus pluvialis cells under high-intensity light in the combined action of Rose Bengal photosensitizer has been established. It was revealed that when Rose Bengal was used as an additional inducer of carotenogenesis in high-intensity light, the dry weight of the Haematococcus and the diameter of the cells in suspension increase compared to the action of only high-intensity light on algae cells. The observed increases in dry weight are significant and reach 40 % excess over control. We suggest that the increase in dry weight, Haematococcus cell diameter and astaxanthin yield when H. pluvialis photosensitizer is added to the incubation medium against the background of high-intensity light is not associated with increased stress (since the used concentrations of Rose Bengal are too small to induce photo-oxidative stress), but the signaling properties of the generated Rose Bengal singlet oxygen, which may be the primary agent in the transduction of a signal that triggers increased synthesis of astaxanthin in H. pluvialis cells.


BACKGROUND
 Technological developments have accelerated notably in the field of telecommunications in the last few decades. Smartphone use has grown in providing healthcare for patients with low back pain (LBP), but the literature lacks an analysis of the use of smartphone apps.

 OBJECTIVE
 This scoping review aimed to identify current areas of smartphone app use for managing LBP. We also aimed to evaluate the current status of the effectiveness or scientific validity of such use and determine perspectives for their potential development.

 METHODS
 We searched PubMed, PEDro and Embase for articles published up to May 2021 that investigated smartphone use for LBP healthcare and their purpose.

 RESULTS
 We included 42 articles: randomised controlled trials (RCTs) (n=12), study protocols (n=6), reliability/validity studies (n=6), systematic reviews (n=7), cohort studies (n=4), qualitative studies (n=5), and case series (n=1). The purposes of the smartphone app were for 1) evaluation, 2) telerehabilitation, 3) self-management, and 4) data collection. Self-management was the most-studied use, showing promising results derived from moderate- to good-quality RCTs for patients with chronic LBP and patients after spinal surgery. Promising results exist regarding evaluation and data collection use and contradictory results regarding measurement use.

 CONCLUSIONS
 This scoping review revealed a growing scientific literature regarding the use of smartphone apps for LBP patients. The identified purposes point to current scientific status and perspectives for further studies including RCTs and systematic reviews targeting specific usage. Caution should be taken to monitor the impact of smartphone-related compulsive behavior.


A growing number of 18th century ornamental wall paintings have been explored and published in country houses and burgher's dwellings. They are never signed, the painters are usually anonymous. A few archival documents, contracts that may be associated with such assignments are presented now. Jakab Ignac Fabricius of Miskolc signed a contract with Countess Ludmilla Forgach to decorate a room and correct the decoration of another in Edeleny in 1780. Since the contiguous figural decoration of the walls of six rooms of this mansion has been attributed to Ferenc Lieb (on the basis of a contract of 1769 and other works of his), the purely ornamental decor of the seventh room in the western wing of the mansion might have been the work of Fabricius, who was the son-in-law of Lieb, by the way. Other painters and gilders were at work in Edeleny, too: the Latin contract of Janos Voronieski dated 1765 also covers the ornamental decoration of a room, the presence of Istvan Nits, painter from Eger in 1768 suggests a s...


Prothrombin contains γ-carboxyglutamic acid residues, synthesised at a post-translational step requiring vitamin K quinol, carbon dioxide, molecular oxygen, and a carboxylating system solubilised from liver microsomal fractions of rats (normal and vit.K deficient) and calves by non-ïonic detergents. The reaction is assayed by the incorporation of 14C into prothrombin precursor or the pentapeptide, Phe-Leu-Glu-Glu-Val. Superoxide dis-mutase reduces the incorporation (50% inhibition at 300μM) and so too do copper chelates with known dismutase activity: 50% inhibition at 60μM copper (II) aspirinate, 127μM copper (II) penicillamine and 152μM copper (II) tyrosine. The superoxide anion is postulated as a primary product of reduced Vitamin K and dioxygen. Catalase also inhibits at high concentrations (> .5mM), possibly by shifting the equilibrium to favour dismutation or b; preventing production of an 'active carbon" species via hydrogen peroxide. So far it has not been possible to replace Vitamin K with active intermediates, such as t-butyl hydroperoxide, which also inhibits the action of the vitamin, possibly due to the formation of Vitamin K 2,3-epoxide. These results point to the involvement of radical species in the Vitamin K dependent carboxylation of prothrombin.

RoboCup simulator team consisted entirely of computer-evolved players developed with genetic programming (Koza 1992), a branch of evolutionary computation that uses natural selection to optimize over the space of computer algorithms. Unlike other entrants that fashioned good softbot teams from a battery of relatively wellunderstood robotics techniques, our goal was to see if it was even possible to use evolutionary computation to develop high-level soccer behaviors that were competitive with the human-crafted strategies of other teams. Although evolutionary computation has been successful in many fields, evolving a computer algorithm has proven challenging, especially in a domain such as robot soccer. Our approach was to evolve a population of teams of Lisp s-expression algorithms, evaluating each team by attaching its algorithms to robot players and trying them out in the simulator. Early experiments tested individual players, but ultimately, the final runs pitted whole teams against each other using coevolution. After evaluation, a team's fitness assessment was based on its success relative to its opponent. This fitness score determined which teams would be selected to interbreed and form the next generation of algorithms. The RoboCup soccer simulator makes evolutionary computation extremely difficult. The simulator gives noisy data, limited sensor information, and complex dynamics. Most problematic is that the simulator runs in real time; even at full throttle, games can take many seconds or even minutes. Unfortunately, evolving a team of 11 soccer players can require hundreds of thousands of evaluations; so, in the worst case, a single soccer evolution run could take a year or more to complete. To keep the number of evaluations to a minimum, we severely limited the population size, which demanded special customizations to prevent the population from converging to a suboptimal strategy. We also cut down the number of evolved algorithms by grouping players into squads, with one algorithm to a squad, or using one single algorithm for the entire team (Luke and Spector 1996). We performed runs for both strategies; by the time of the competition, the single-team strategies had better fitness. To further speed up runs, evaluations were run in parallel on an ALPHA supercomputer cluster. Because we had only one shot to evolve teams, we cannot make rigorous scientific claims about population development. Nonetheless, an admittedly anecdotal observation is still interesting. After a hesitant start, most early teams soon began to learn the worrisome suboptimal kiddy soccer strategy: Everyone go after the ball, and kick it to the goal (top figure). Thankfully, eventually players learned to hang back and protect the goal and, ultimately, disperse through the field to provide better coverage (bottom figure). By the end of the final runs, the computer had produced teams that, as appropriate, passed to teammates, blocked the ball, protected different parts of the field, and tried to stay open. Our submission was surprisingly successful, beating its first two hand-coded competitors before succumbing. Hopefully this and other experiments will show that evolutionary computation is ready for a number of problems that previously have only been the purview of human ability. – Sean Luke Articles

Occasionally, the tap water of housing area at Gambang, Pahang is detected to have the
presence of odour and brownish in colour. The water filter cartridge turns brown rapidly.
This issue has harassed the residents and caused doubtfulness by using the water supply.
In order to verify this perception, tests of colour, turbidity, Biochemical Oxygen
Demand (BOD), total solids (TS), total suspended solids (TSS) and total dissolved
solids (TDS) were carried out by using the water supply from five houses in Gambang
area. The results obtained were compared with the water quality standards. A pre-water
filter was designed to solve this problem, which included an aeration and filtration
process. The aeration process was induced by a free-fall in the system. Hence, the
relationship between the height of the fall and dissolved oxygen level was determined to
obtain the best and most feasible height in the aeration process. A high rate dual media
filter with filter media of graded sand and activated carbon made from coconut shells;•
and a support layer of gravel was used for the filtration process. By the completion of
pre-water filter design, a running of the water filter was carried out and water after
passed through the filter was then tested with colour, turbidity, BOD, TS and TSS
amount, along with the confirmation of increased in dissolved oxygen value to ensure
the water freshness. The results obtained were compared with the results of water before
induced to the pre-water filter, and also the water quality standard. From this research,
the final model of the pre-water filter was able to decrease above
50
%
of the colour,
turbidity, BOD, TS and TDS; and increased the dissolved oxygen level for 5.3
1%.


The College of Engineering of the University of Puerto Rico-Mayaguez Campus (UPRM) established the UPRM Pre-College Engineering Program in 1992. The program targets rising senior high-school students with a demonstrated interest in and potential for math and science related professions. This paper presents an overview of the program and an assessment of its effectiveness in meeting its objectives. Detailed statistics are presented concerning the formative and summative evaluations performed for each session during the program's history. Also, the project's success in attracting students to engineering careers is discussed.


Post-translational modification of proteins by the addition of small ubiquitin-related modifier (SUMO) is a dynamic process, in which deSUMOylation is carried out by members of the Sentrin/SUMO-specific protease (SENP) family. While identification of SUMOylation sites at global scale has made great progress, much less effort has been made on the SENP family-dependent deSUMOylation. Here we report a dataset of 3,763 high confident SUMO1 modification sites and their dependence on the 6 members of SENP proteins. Interrogation of the dataset led to the discovery that SENP3 regulates the innate immune response via deSUMOylation of DHX15 and PCBP2 and recruitment of inflammatory molecules. Collectively, this dataset presents a site-resolved network of the SUMO-SENP system, providing information for potential substrates of the SENP proteins.


Introduction: Pregnancy, delivery and postpartum periods are associated with fast changes leading to decreased self-confidence, anxiety, stress or even maternal depression impairing their quality of life (QOL). Although considered important, QOL of women during pregnancy is poorly understood. The aim of our study was to assess factors influencing QOL during first trimester of pregnancy. The secondary goal of our study was to evaluate whether QOL during first trimester of pregnancy is associated with newborn weight. Materials and methods: A prospective cohort study was performed including pregnant women during the first trimester visit. Our questionnaire consisted of the SF-36 QOL questionnaire, Wexner fecal incontinence scale, and other additional information. The SF-36 questionnaire mental (MCS) and physical (PCS) health scores were used in order to evaluate QOL of women during first trimester of pregnancy. Two multiple logistic regression models were created in order to determine independent variables that influence the QOL. Results: 440 pregnant women were included in the study. The two main domains that were used in the study were MCS and PCS, their medians were 50.0 (25.0; 50.0) and 50.1 (39.4; 59.0) points respectively. From the two logistic regression models we determined several independent factors that influence QOL of women during the first trimester of pregnancy. Additionally, we determined that women who reported worse QOL tended to give birth to newborns large for their gestational age. Conclusions: We found several significant variables that influence QOL of women during the first trimester of pregnancy. We also found that that lower MCS and PCS scores during the first trimester are associated with newborns large for gestational age.


TO THE EDITOR: We read with interest the article by Yang et al.1 (Yang MMH, Ryu WHA, Casha S, et al. Heterotopic ossification and radiographic adjacent-segment disease after cervical disc arthroplasty. J Neurosurg Spine. 2019;31(5):660–669). By retrospective analysis of 58 levels of cervical disc arthroplasty (CDA) in 45 patients with 1or 2-level of CDA, the authors concluded that high-grade heterotopic ossification (HO) was predicted by residual exposed endplate (REE) and that CDA was protective against further degeneration at the index level. Although the authors should be applauded for their attempt to mitigate HO after CDA, we have to respectfully point out a few issues with the report. The statistics could use some improvement. Although a total of 58 levels of CDA was stated and used for calculation in the report, there were only 57 levels demonstrated in Table 1 (33 patients who had 1-level and 12 patients who had 2-level operations; 33 + 2 * 12 = 57). Furthermore, for REE, the most critical results of the study should be divided into four groups (0–1, 1–2, 2–3, and > 3 mm) independently, rather than three groups (> 1, > 2, and > 3 mm) and additively calculated (Table 2). The omitted 0–1-mm REE very likely skewed the results of the study, given the already small sample size. Last, the separation of blue and red lines in Fig. 2 was repetitive and redundant because the highversus low-grade HO was merely reciprocal. The study also might be limited by neglect of many other reported risk factors of HO after CDA.2–8 For example, Wu et al. demonstrated that pre-existing calcified disc or spondylosis at the indexed level of CDA was associated with more than 9 times the incidence of HO.8 Smoking and the change in mobility after surgery also played an important role on the incidences of HO.4,9 Nevertheless, these cases of HO were usually indolent and rarely caused adverse radiological or clinical outcomes, or required reoperations.4–6,8 The authors should be commended for demonstration of HO in various (5) brands of devices included in the study. The common phenomenon of the undesired bone formation—which fortunately seldom caused problems— after CDA prompts future investigations of the nature and prevention of HO. Given the proximity (at the index level) and demographic influence (patients' preoperative characteristics) on the development of HO, it remained elusive whether CDA could hold or decelerate degeneration even at the index level. The protective effect of CDA on either the index or adjacent levels needs further evaluations.10


The linear stability of a viscoelastic liquid thread surrounded by another viscoelastic liquid is studied. If in the undisturbed state there is no relative motion between the two liquids the results hold without requiring any rheological modeling of the liquids. The complex viscosity, or equivalently the complex modulus will govern the stability behaviour. If in the undisturbed state there is a relative motion (say of velocity u), then model fluids are required and the present analysis will be the model‐free u → 0 limit of such studies.


In the present paper, the solution of nonlinear elliptic boundary value problems (b.v.p.1 on parallel machines with Multiple Instruction Multiple Data (MIMD) architecture is discussed. Especially, we consider electro-magnetic field problems the numerical solution of which is based on finite element (FE) discretizations and a nested Newton solver. For solving the linear systems of algebraic FE equations in each Newton step, parallel conjugate gradient methods with a Domain Decomposition preconditioner (DD-PCG) as well as parallelized global multigrid (GMG) methods are applied. The implementation of the whole algorithm, i.e. the mesh generation, the generation of the FE equations, the nested Newton algorithm, the DD-PCG method and the GMG method, is based on a non-overlapping DD data structure. The efficiency of the parallel DD-PCG methods and the parallelized GMG methods, which are embedded in the nested Newton solver, are compared. Furthermore, the performance on different machines (GC Power Plus, Multicluster with transputers T80.5, and workstation cluster) is demonstrated by numerical results.


Doxorubicin (DOX) is an anthracycline antibiotic and a quinone-containing chemotherapeutic drug used for various types of solid and hematological cancers. However, it causes many toxic side effects, including cardiac, renal, hematological, and testicular. The current study investigated the prophylactic and ameliorative effect of n-acetylcysteine (NAC) against DOX-induced cardiotoxicity in albino rats. Sixty rats were divided into six groups. Negative Control group: rats received food pellets and tap water ad libitum. NAC treated (positive control) group: rats received NAC (400 mg/kg/p.o.) Every other day for 28 days. DOX-treated group: rats received DOX (5 mg/kg, i.p.) for four weeks on days 1, 7, 14 and 21. NAC pretreated group: rats received NAC (400 mg/kg/p.o.) every other day one week earlier and then along with DOX (5 mg/kg/ i.p.) for the next four weeks on days 1, 7, 14 and 21). NAC1+DOX treated group : rats received NAC (400 mg/kg/ p.o.) every other day started at the first day of the experiment till the end of the experiment and DOX (5 mg/kg/ i.p.) for four weeks on day 1, 7, 14 and 21. NAC2+DOX treated group: rats received NAC (800 mg/kg, p.o.) every other day started at the first day of the experiment till the end of the experiment and DOX (5 mg/kg, i.p.) for four weeks on day 1, 7, 14 and 21. The present results showed a significant increase in the serum levels of LDH, CK-MB, CTn-I, plasma level of malondialdehyde (MDA). Whilst, plasma level of reduced glutathione (GSH) and Erythrocyte lysate level of glutathione peroxidase (GSH-Px) were significantly decreased. Moreover, there were histopathological abnormalities in the cardiac tissue of DOX-treated rats, was recognized by disrupted cardiac muscle fibers and foci of degeneration of the myocardium. The present study demonstrated that NAC has a cardioprotective effect on the cardiac damage induced by DOX, through inhibition of inflammation and oxidative stress. This cardio protective effect was more pronounced in both NAC pre-treated and concurrent (NAC1+DOX & NAC2+DOX), as it produced a significant increase in GSH and GSH-Px levels, a significant decrease in MDA, LDH, CK-MB, and CTn-I, and more improvement in the histopathological abnormalities, without a significant difference either between NAC pre- treated & concurrent groups or between groups of concurrent one (NAC1+DOX & NAC2+DOX).


PROFESSOR E. WE~H'O:N HFRST spoke on virus diseases. He said that viruses were very small and possibly constituted the link between the animate and inanimate worlds. They were not known to multiply apart from living cells, in which they were protected against deleterious agencies such as chemotherapeutic remedies and immune serum, a point of importance in the prophylaxis and treatment of virus diseases. Many viruses having a more or less selective action on the nervous system were known, and several new virus encephalitides had been described in recent years. In addition a vtrus had been found to be the eetlologtcal agent in lymphocytic choriomeningitis. Many neurotropic viruses reached the nervous system by way of the nerve fibres themselves. In such instances the nose would appear to offer a favourable portal of entity. Influenza, the common cold and psittacosis were respiratory diseases due to viruses. Recently an effort to separate true influenza from the so-called febrile catarrhs had been made on a clinical basis; but it was too early to be dogmatic on the symptomatology of infections with specific influenza virus.


Currently, as a result of the extensive use of water resources worldwide, their quantitative reduction and quality deterioration are causing a number of problems. Therefore, studying the hydrological characteristics of existing water resources in the Bukhara region is considered one of the urgent problems. Bukhara region has its own unique hydrological characteristics due to the fact that it is completely in the desert zone, the climate changes sharply, the temperature is high, warm winds constantly blow, and it does not have its own natural water source.

Chair: Michele Johnson, York University "Michele Johnson" 1)      Paul E. Lovejoy, York University Paul E. Lovejoy  "Africa Here: Itineraries of African Canadian Memory and the UNESCO Slave Route Project" In keeping with the objectives of the UNESCO Slave Route Project, the Tubman Institute has launched an initiative to identify and recognize historic sites of memory of the African Canadian experience in Canada as a UNESCO "Itinerary of Memory." The purpose of the initiative is to raise public awareness of the presence of people of African descent in Canada. The initial focus of this initiative is on historic sites in Ontario, including sites associated with the well-known struggle for freedom of the legendary Underground Railroad but also to identify sites that establish the enslavement of Africans and people of African descent, in recognition that slavery was legal in Canada until Emancipation in 1834.  2)      Hilary Dawson, Harriet Tubman Institute, York University  "Hilary Dawson" "Locating Sites of Memory: Tracing an Itinerary of Memory for the African Canadian Experience"  UNESCO's Itineraries of Memory Project complements the International Year for People of African Descent , designated by the UN for 2011. The Harriet Tubman Institute's contribution to Itineraries of Memory is Sites of African Canadian Memory . This project commemorates places of significance to slavery, resistance and the Underground Railroad in Canada. A phased approach has been adopted, and in its initial stage, the Harriet Tubman Institute is developing a process for designating Ontario sites evocative of individual acts of resistance, homesteads, settlements, faith centres and agricultural colonies created for the purpose of African American refugee resettlement. In a future phase, new research will be undertaken to redress the errors of earlier histories and to identify previously unknown or undocumented sites, events and communities. Ultimately, the plan is to document Sites of African Canadian Memory across Canada, and to have the results publicly available in an online database.  3)      Karolyn Smardz Frost, Harriet Tubman Institute, York University  karolyn smardz frost "Slavery, Resistance and the Underground Railroad in Toronto" Toronto is a very significant site of African Canadian Memory.  Enslaved women, men and children once worked the fields in the colonial Town of York, as Toronto was called until 1834.  But in 1793, spurred by a Black veteran's description of a single woman's spirited resistance, Upper Canada's Lieutenant Governor passed the first antislavery legislation in the British Empire (by some 40 years!).  By the 1830s Toronto had become a centre of abolitionist activism. The city was a major terminus of the Underground Railroad, with a Black population of between 1500 and 2000 by 1865. This paper recounts the early heritage of peoples of the African diaspora in Canada's largest city, and calls for the commemoration of the places, events, and individuals evocative of 19 th century Toronto's role in the African Diaspora.

McAfee SecurityCenter Firewall is one of the most popular security software installed on millions of Internet connected computers worldwide. "McAfee claims that if you have installed McAfee SecurityCentre with anti-virus and anti-spyware and Firewall version 9.3 then you always have the most current security to combat the ever-evolving threats on the Internet for the duration of the subscription". In this paper, we present our findings regarding the effectiveness of McAfee SecurityCentre software against one of the most popular Distributed Denial Of Service (DDoS) attack, namely Ping-flood attack on the computer which has McAfee SecurityCentre installed. The McAfee SecurityCentre software has an in built firewall which can be activated to control and filter the Inbound/Outbound traffic. It can also block the Ping Requests in order to stop or subside the Ping based DDoS Attacks. To test the McAfee Security Centre software, we created the Ping traffic in the controlled lab environment of Networking Research Lab here at The University of Texas-Pan American. It was found that the McAfee Firewall software itself was incurring DoS (Denial of Service) by completely exhausting the available memory resources during its operation of stopping the external Ping Attack.


Simulator. The VHDL-AMS model presented here implements the system model of a portal crane with embedded control as described in the Case Study by Eduard Moser and Wolfgang Nebel, Proc. DATE'99, pp. 721-724. This model incorporates both the continuous description of the crane dynamics and the embedded digital controller and the simulator used is SystemVision from Mentor Graphics. SystemVision is a state-of-the-art VHDL-AMS simulator which provides co-simulation capability for mixed signal designs as well as graphical design, waveform viewing etc. Model. Figure 1 shows the system diagram of the model. The plant (i.e. car and load) is described by three differential algebraic equations (DAEs). In VHDL-AMS, DAEs are simply defined as simultaneous statements, no matter whether the equations are explicit or implicit. The sensor updates the car position and angle signals and sends them to the controller. The controller computes the values of drive voltage and brake signal according to the control signals from the crane operator and the monitoring signals from the sensor. The actuator is another DAE connecting the drive force and the drive voltage.

Discovery proceeds in stages of construction, evaluation, and revision. Each of these stages is constrained by what is known or conjectured about what is being discovered. A new characterization of mechanism aids in specifying what is to be discovered when a mechanism is sought. Guidance in discovering mechanisms may be provided by the reasoning strategies of schema instantiation, modular subassembly, and forward/backward chaining. Examples are found in mechanisms in molecular biology, biochemistry, immunology, and evolutionary biology.


Background: Head and neck trauma is an increasing cause of morbidity and mortality in India. The mode of trauma has varies with geographical progress and it is important to understand the factors associated with severe head injury among this cohort. Methods: This was a retrospective observational study of all adult trauma patients with head and neck trauma presenting to our emergency department (ED). Details of the incident, injuries and outcome were analyzed. Results: During the 3-month study, the ED attended to 16,169 patients with 2022 being trauma victims. Among them, 51.4 3% (n = 835) adults who sustained head, face or neck trauma and hence were included in the final analysis. Overall, RTA s were the predominant mode of injury (81.2% (n = 678), followed by fall on level ground (6.5%; n = 54), fall from height (5.1%; n = 43) and assault (3.7%; n = 31). A history of consuming alcohol prior to the incident was obtained in 16.2% (135) of the patients. Head, face, and neck injuries were seen in 74.9% (n = 626), 64.1% (n = 536), and 4.9% (n = 41) of patients respectively. Bivariate analysis showed male sex (90.3% vs. 76.8%; unadjusted odds ratio [OR]: 2.81, 95% confidence intervals [CI]: 1.19–6.64; P = 0.018) and pedestrian injuries (19.4% vs. 8.5%; unadjusted OR: 2.57, 95% CI: 1.30–5.07; P = 0.006) to have a statistically significant association with sustaining severe head injury. Conclusion: Head and neck trauma comprises a significant proportion of patients with trauma with RTA and falls being the most common causes. Among patients with head and neck trauma, males and pedestrians have an increased odds of sustaining severe head injury (Glasgow Coma Scale ≤8).


Public policies related to the criminal justice system in the United States ultimately reflect the attitudes of its citizens. It is surprising, therefore, how few studies have investigated influences on attitudes about criminal justice issues and how narrow the scope of such investigations has been. In this study, we examined the effects of education on attitudes toward several criminal justice issues in college students enrolled in a senior-level forensic psychology course compared to a nonpsycholegal psychology course. Results indicated that education about public policy issues influenced students' attitudes toward the death penalty, prison reform, and the insanity defense. In addition, we examined preexisting differences in these attitudes based on demographic and other status variables (i.e., race, gender, academic class standing) and found that these variables were associated with differences in attitudes about criminal justice issues in a much more complex way than previously considered in the extant literature.


In the beginning geophysicists talked to each other in order to figure things out. But, they could not figure it all out so they formed groups to get more brainpower working on the problems that faced them. Eventually, geophysicists, being political animals, formed local geophysical societies to formalize the process of getting together, exchanging ideas, and making contacts. However, they found that, even with local societies, there was still not enough brainpower to cover all the problems and to expose themselves to other problems (and solutions) they had not considered. So, in 1930, they formed the Society of Exploration Geophysicists. The governing body of this new Society was a Council made up of representatives of the local societies. Thus the local societies have been important from the beginning. But why have these local societies continued to be so important in the profession? It is largely because they provide the basic ties which create a sense of wholeness, of association, and of social value.

There has been a steady rise in interest in qualitative research methods in the area of learning disability over recent years. Discourse analysis has found relatively little use though, particularly in studying the experiences of people with learning disabilities directly, rather than the accounts of non-disabled informants. The present study used a discourse analytic approach in examining the accounts of women with learning disabilities, in order to arrive at an understanding how they position themselves in relation to gender and disability. The results indicate that, while the learning disability literature and services are largely 'gender blind', for women with learning disabilities gender and disability cannot be separated. Instead, they may be faced with marked contradictions and dilemmas when they position themselves within dominant discourses of gender, while also subject to powerful discourses of disability.

Study on the Bok Bak fault in Peninsular Malaysia reveals it to be a predominantly dextral brittle–ductile strike slip fault zone. This fault zone is characterized by gentle to sub-horizontal NE stretching lineation. The deformation occurred in a brittle–ductile domain. 40 Ar/ 39 Ar radiometric dating of biotite from the mylonite assigns an age of 136.1 ± 1.4 Ma. This age is the first reported radiometric dating of the Bok Bak fault, suggesting that the fault affected Sundaland prior to the collision between India and Asia, and therefore indicates an early faulting in the Malay Peninsula.


Purpose
Although place branding is increasingly popular in research as well as in local, regional and national political agendas, the theoretical foundations of the place branding discipline are still underdeveloped. By embracing the stream of identity-based studies, this paper aims to attempt to demonstrate that place brands can be usefully approached through an emphasis of their cultural traits and the practical connection between culture, identity and image.

Design/methodology/approach
In constructing its theoretical arguments, the paper challenges the place branding model propounded by Kavaratzis and Hatch (2013), and uses practices as units of analysis. The paper conducts a brief review of the principal tenets of practice theory(IES) and uses structuration theory as a theoretical device to demonstrate how this theory can provide a (still lacking) theoretical anchorage for the place branding process.

Findings
The usefulness of structuration theory for understanding the place branding process is analysed at both the strategic and tactical levels by means of two illustrative examples. Structuration theory proves to be a solid theory which links the constitutive elements of the place branding process, i.e. culture, identity and image, and to inspire further theoretical elaborations and empirical efforts grounded on this theory.

Originality/value
This is the first paper which uses practice theory(ies) in general and structuration theory in particular to explain the place branding process. The theoretical arguments advanced provide valuable guidance for further theoretical elaborations and empirical applications.

This paper explores St. Paul of the Cross's passion-centred spirituality as a context for avoiding the distortions of such spirituality and promoting proper praxis. These distortions are not the legacy of Paul of the Cross himself, but the fact that his contemplation of the passion was primarily performative and mystical, along with the lack of a systematic theology on the passion-death-and resurrection, there remains a context wherein distortions of passion-centred approaches can occur.

The paper then presents some aspects of Bernard Lonergan's thought on lex crucis and also from his Trinitarian work in order to provide a theological framework (orthotheoria). This framework can help prevent the distortions of such a passion-centred spirituality and guide orthopraxis of passion-centred spiritualities. In the final section we explore some insights from Buddhism that are consonant with both Paul of the Cross's spirituality and Lonergan's law of the cross as fruits of the Spirit and seeds of the Word.


Aciculatin, a flavonoid extracted from Elephantopus scaber L., has an uncommon C‐glycoside structure and superior anti‐cancer activity. This study firstly demonstrates that aciculatin induces cells death in time‐ and dose‐dependent manners in HCT116. After 10 μM aciculatin treatment, cells arrest in G1 phase and undergo apoptosis subsequently. It is shown that tumor suppressor protein p53 accumulate in this pathway. We further compared WT and p53−/− HCT116 and found that p53−/− HCT116 is more resistant to aciculatin. The same results can be achieved by knockdown of p53 level in WT cells. These data suggest that p53 plays a crucial role in aciculatin‐induced apoptosis. Previous study has defined aciculatin a DNA‐binding agent in vitro. However, DNA damage signaling is not significant in this case, which implies there are some other events leading to p53 activation. Furthermore, aciculatin can down‐regulate MDM2, the negative regulator of p53, in early stage. This may contribute to p53 accumulation. Taken all together, these results indicate that aciculatin induces G1 arrest and apoptosis of HCT‐116 cells via p53 activation.


The aim of the study was to study patterns in the incidence of lymphomas and its epidemiological characteristics in the Republic of Khakassia for 2014. The research was conducted by retrospective analysis. The following epidemiological features are revealed: NHL is more common; LGM often ill persons young and middle age, and the NHL people in the older age groups; incidence among men is higher than women's; among refined morphological variants LGM disseminated sclerosis and nodular lymphoid predominance, among the NHL is most prevalent diffuse non-Hodgkin's lymphoma; it is noted that the NHL is more common in urban populations.


Abstract The destruction of Salmonella typhimurium, S. thompson, S. tennessee, and S. kentucky in heated liquid skimmilk was compared with their resistance to milk spray drying at different temperatures. All four strains exhibited relatively similar heat sensitivities in liquid milk, with D values at 60C of from 21.3 to 34.5sec. This was not true for inactivation during spray drying. At each temperature S. tennessee was much more resistant to spray drying, amounting to population decreases of 2 to 3 log cycles less, and calculated D values approximately 2 to 5 times greater, than for the other strains. The exceptional resistance of S. tennessee to spray drying would not have been predicted from D values in heated liquid milk.


In this paper, an updated Smoothed Particle Hydrodynamics (SPH) method based on the Simplified Finite Difference Interpolation scheme (SPH_SFDI) is presented to simulate the failure process of ice. The Drucker–Prager model is embedded into the SPH code to simulate the four point bending and uniaxial compression failure of ice. The cohesion softening elastic–plastic model is also used in the SPH_SFDI framework. To validate the proposed modeling approach, the numerical results of SPH_SFDI are compared with the standard SPH and the experimental data. The good agreement demonstrated that the proposed SPH_SFDI method including the elastic–plastic cohesion softening Drucker–Prager failure model can provide a useful numerical tool for simulating failure progress of the ice in practical field. It is also shown that the SPH_SFDI can significantly improve the capability and accuracy for simulating ice bending and compression failures as compared with the original SPH scheme.


The traditional AFM(atomic force microscope)systems based on PC(personal computer) can not meet the requirement of high-speed scanning.So the research on high-speed AFM with advanced control system is becoming a hotspot in this area.This paper introduced a new AFM system that uses DSP(digital signal processor) as control core.Tasks like probe auto-approaching/departing,scanning voltage generating,digital close-loop feedback control and so on are all implemented under the control of DSP.Due to the ability of high speed of data processing of DSP,the maximum line scanning rate acquired presently by our experiments rises as high as 55 Hz with the resolution of 512×512.Moreover,experiments showed that the whole system has good performance of imaging,even though it works at a very high scanning rate.


To achieve accurate low temperature measurement of a material under shock-loading, we performe a series of experiments of shocked Pb and Cu targets partially released thanks to the use of a LiF anvil. In order to reduce uncertainties of the true interface temperature due to the lack of knowledge of emissivity, a method consists in artificially increasing the dynamic emissivity of the material up to an apparent value of approximately 0.85 by the use of an emissive layer. The detected radiance is then amplified and the range of dynamic emissivity is restricted. Promising results at material/LiF interface at about 8 GPa obtained with an emissive layer of ReSi2 indicate that the mechanical, thermal and optical properties of this layer can be characterized and the temperature of the material can be deduced. This paper examines different parameters (nature of the material, layer thickness) potentially influencing the measured radiances at this complex interface.


Entrepreneurial orientation is a theoretical concept defined by three dimensions: innovativeness, proactivity and risk-taking. Entrepreneurial orientation researchers suggest that entrepreneurial orientation is a concept that pervades through all organizational levels of the company (Wiklund and Shepherd, 2005; Wales, Monsen and McKelvie, 2011). Although focus of early research on the concept has been oriented on the company level and its influence on profitability, cotemporary research has put much accent both on research of individual entrepreneurial orientation, as well as on research of entrepreneurial orientation of non-profit companies. Having on mind the fact that contemporary university should be an incubator of practical and applicable knowledge, but also being aware of many practical dimensions related to university management, in this paper we will focus on investigating whether there is a rationale for incentives for universities and students to be more entrepreneurially oriented by systematizing the findings of research papers whose focus has been on measuring individual entrepreneurial orientation of students and on researching different dimensions of entrepreneurial orientation of universities.


We analyze the specifics of the organization of Russian pilgrims transportation to Palestine, the activity of the Russian Society of Shipping and Trade in the organization of pilgrims delivery is evaluated, the effectiveness of the created passenger departure system is analyzed. The relevance of the study consists in a comprehensive study of the Russian Society of Shipping and Trade activities in the arrangement of pilgrimage routes, the role of the created transport infrastructure in the formation of the Russian presence in the Orthodox East. The novelty of the work is determined by the study of interdepartmental cooperation of secular structures in the arrangement of Russian Palestine, the introduction of new sources from the B.P. Mansurov's fund (SATR. F. 972) into the scientific circulation. It is shown that the inclusion of the Russian Society of Shipping and Trade in the Palestinian project made it possible to find acceptable solutions for transporting a huge number of Russian pilgrims. For the first time in the history of Russia, a centralized departure of pilgrims to Palestine was organized, and conditions were created for their reception and placement in the Holy Places. We pay attention to the fact that the Russian Society of Shipping and Trade leadership was to not only facilitate the pilgrims transportation, but also take on part of the costs of organizing the Jerusalem consulate, while combining the posts of consul and chief agent of the Society in one person. We reveal that the infrastructure creation for the reception and accommodation of pilgrims in Palestine opened a new stage in the development of the Russian presence in the Holy Land, strengthened the cultural and religious ties of Russia and the Middle East region.


The degradation of fungicide oxadixyl in soil amended with manure, chemical fertilizers, heavy metals and detergent was studied. The degradation of oxadixyl in the soil was slow, but became to be fast after the lag phase of about 14 days. The half-life was 10.5 days. The degradation rate was accelerated largely by the amendment of manure. Potassium also promoted the degradation rate but nitrogen and phosphate did not. The heavy metals inhibited the degradation rate, in order of Ni, Cd, Cr, Cu, and Zn. The degradation rate was declined greatly with the addition of synthetic detergent. The microbial biomass and the respiration rate in the soil were increased by the amendment of manure and chemical fertilizers, but decreased by the addition of heavy metals and cleaner. The degradation rate of oxadixyl was positively correlated with the microbial biomass and the respiration rate.


Touschek lifetime depends on the electron beam polarization through intrabeam scattering. Hence, the polarization of the electron beam can be studied using lifetime measurement. In this paper, we will first discuss the dependency of Touschek lifetime on beam polarization. We will then report our feasibility study of using Touschek lifetime to measure polarization of the electron beam in the Duke storage ring.


The work reveals the specific features of book art, which integrates the achievements of artistic means and forms, as well as scientific research. The authors focus on the regional Arctic locus of book art. The article traces the origin of Yakut book illustrations from the first attempts of amateur artists on the pages of the periodical press in the 1920s to the activities of various institutions: the scientific research society "Sakha kehskileh" (1925–1930), the cultural and educational societies "Manchaary" and "Sakha omuk" (1920–1930) and The Union of Soviet Artists of Yakutia (since 1940s), that pioneered the accumulation of cultural practices and development of art trends in the region. The characteristics of the first Yakut artists-illustrators are presented: P. P. Romanov, who created illustrations to the image of the heroic Olonkho epos "Byudyuryubet Myuldzu Bege" and G. M. Turalysov, who illustrated the collection of poems and songs by Ilya Chagylgan "The Rise", thus initiating the development of professional graphic art in Yakutia. The creation of the art school in Yakutsk in 1945, the emergence of publishing houses became a new page in the development of the book graphics in the works of the first graduates of the school — E. Shaposhnikov, E. Shestakov, M. Lukin, O. Kovalevsky, V. Petrov and others. Special attention is paid to creativity of E. S. Sivtsev, the founder of Yakut prints. The First (1958) and The Second (1963) All-Union Exhibitions of prints opened to the public the names of Yakut illustrators. Later A. P. Munkhalov exhibited his series of engravings "My North" at the International Exhibition "Intergraphy — 67" in Berlin, and his engraving "Listening to the World" was included in the German school textbooks. The article also reveals the modern stage in the development of book art, from the activities of "Bichik" publishing house to graduate projects of The Arctic Institute of Culture and Arts and The Yakutsk School of Art.

A DNA microarray is considered to be a multiplex research tool used for gene expression studies. It is a twodimensional array on a substrate surface that permits for the assaying of vast amounts of biomaterials. The novel Alternative, Multistranded, Plasmid, and Helical Transitional DNA and RNA Microarrays have been developed that allows for the immobilization of intact, nondenatured, double-stranded (ds-) DNA, ds-RNA, and alternative and multistranded nucleic acids. It goes beyond the limitations of conventional DNA microarrays. It also allows for the study of transitional changes that occur in the structure of DNA and RNA. Alternative types of DNA, RNA and multistranded nucleic acids are immobilized by a variety of different surface chemistries onto a novel substrate surface. This technology represents the next generation of DNA and RNA microarrays, which will aid in the characterization of nucleic acid structure and function, and accelerate the discovery of drugs that bind to exotic nucleic acids and transitions in DNA and RNA. These novel nucleic acid microarrays can be used to improve the study of DNA and RNA structure, gene expression, drug discovery and development, and treatment of various diseases.


The government has warned primary care trusts to think again before closing community hospitals because of current financial pressures in the NHS. The health minister Lord Norman Warner told an audience of about 100 managers last week that he was concerned about panic decisions by primary care trusts to close such hospitals. Keeping them open could actually save the NHS money, he added.

Guidance on the future of community hospitals was due to be issued within the next couple of months, said Lord Warner, at the Shaping the Future conference held in London by the NHS Confederation, …


In Reply.— Dr Gottfried's point is valid. However, it should be pointed out that the same is true for all the major coronary heart disease risk factors of blood pressure, serum cholesterol levels, and smoking. That is, although the relative risk may be high for a person, the absolute risk is low and in many persons at high risk the decrease will not develop. This is especially true for the relatively brief time periods of observation for most studies (five to ten years). We appreciate Dr Light's comments. The mechanism he proposes for the increased risk associated with elevated WBC counts is rational. We selected our comments on free oxygen radical production as an illustration of a plausible biologic mechanism for the increased risk. Dr Light provides another and the two are not necessarily mutually exclusive. Indeed, because the WBC count/coronary heart disease and cancer relationships in our study are


The two controller design schemes of pitching control for the aircraft with changing weight parameters are given.The design method of the compromise PID controller,finding the optimum parameters at two end conditions and compromising them,is proved to be simple and practical in simulation tests.The system analysis and simulation tests show that the P-PID and PD-PI controllers designed with the cascade control scheme are of the better robustness.


In a pilot-programme to increase evidence for the history of copper-alloying in ancient Iraq, Syria and Palestine 128 objects in the Ashmolean Museum, Oxford, were tested with a point-source linear X-ray spectrometer for tin, arsenic and antimony. These analyses showed the gradual introduction of tin-copper alloys into Iraq after ca. 2750 b.c. (Early Dynastic IIIA), into Syria a little later and into Palestine by the end of the third millennium b.c., though numerous artefacts continue to be of copper or arsenical-copper until well into the second millennium b.c. at least. With the appearance of tin-copper alloys the percentage of arsenic in the copper objects noticeably declines indicating that the earlier arsenical-coppers were deliberately produced under controlled conditions.


Alternatives to herbicides are needed for weed control. Field studies were conducted in 1994/1995 and 1995/1996 to investigate the nature of forage crop-weed dynamics and to test the effect of single year forage crops on the density and community composition of annual weeds in a following field pea (Pisium sativum L.) test crop. Five spring-seeded forage treatments were compared with wheat (Triticum aestivum L.) grain crops (with or without herbicides for grassy and broadleaved weeds): winter triticale (Triticosecale) (simulation grazed); spring triticale (silage); spring/winter triticale intercrop (silage, then simulation grazed); alfalfa (Medicago sativa L.) (hay); sorghum-sudangrass (Sorghum bicolor [L.] Moench × Sorghum sudanese [Piper]) (hay); and a weedy fallow (silage). A fall rye (Secale cereale L.) grain crop and a sweet clover (Melilotis officinalis L.)/winter triticale double crop (hay, then simulation grazing) were included in the 1995/1996 trial. All forage systems were at least as effective ...


In [5] Swarup states a group theoretic conjecture P2 and shows that P1 =X P2 X the Poincare conjecture, where P1 is a conjecture of Papakyriakopoulos [3]. We give a counterexample to conjecture P2. In [3], Papakyriakopoulos stated a conjecture P1 and showed that P1 implies the Poincare conjecture. In [5], Swarup showed that P1 X P2 w the Poincare conjecture, where P2 is the following. CONJECTURE. Let QP = {a1, b, . . . , ap, bp; ll?.j[a, bil, [a,, b,T]), where p > 1 and T E[ [4p, ], Jp being the free group on a1, b, . . .,a, bp. Then Qp is a nontrivial free product. In this note we show, by means of a counterexample, that conjecture P2 is false. We take p = 2, T = [a,, bl] and suppose that Q2 = A * B, where A and B are nontrivial. Now we observe that, with a slight change of notation, Q2= a, b, c, d; [a, b][c, d], [a, babab]} = (a, b, c, d, x, y; babx-, bxby, abb [ c, d], abababaibabab} = (a, b, c, d, x,y; babx-, bxby, ax?[c, d], ax6r.Wyxy} = {b, c, d, x,y; bx.j7xyxyxl5F, bxbyF, .x[cxyV [c, d] } = {b, c, d, x, y, z; zxy, bxyxyxbx, bxby, xyxy.W2[ c, dl ] = {b, c, d, x, z; bzxibx-, bxbx-z, zxzx[ c, d] }. Let K = (z, x, c, d; [z, x][c, dJ). Then using the Freiheitssatz (see [2] or [1]), we see that the subgroup of K generated by x, z is free of rank two, and so therefore are the subgroups generated by zxz, x and x, zx, respectively. It follows that Q2 is an HNN-extension (see, e.g., [1]) of K by the stable letter b, and hence that the subgroup of Q2 generated by z, x, c, d is naturally isomorphic to K. Now K is not cyclic, and from the results of [4] K is indecomposable with respect to free products. It then follows from the Kurosh Subgroup Theorem that K is contained in a conjugate of A or B, say B. By conjugating the original A and B, we may assume that K is contained in B.

Abstract This paper contains a systematic study on warpage of injection moulded plates and corner products as a function of mould temperature difference and holding pressure. The study is restricted to unfilled amorphous materials. As expected, experiments showed that warpage increased linearly with the applied temperature difference between mould halves. Not expected was that at low holding pressures the plates curved towards the hot side, whereas at high holding pressures they warped towards the cold side. A simple thermoelastic theory is proposed which could explain all observations qualitatively and quantitatively. Standard simulation software, on the other hand, was seen to predict warpage behaviour at the higher holding pressures which was completely opposite to the experimental observations.


Abstract The authors investigated the effect of a mathematical curriculum (CU) developed based on verbal and practical activities on the mathematical competency (MC) and learning behaviors (LB) of preschool children. In a quasi-experimental design, 60 children (5- to 6-year-old girls) were selected using the accessible sampling method. The children were randomly divided into an experimental group and a control group, and the relevant concepts were taught to the children in both groups. While the control group received the typical kindergarten education based on the usual textbooks and worksheets, the CU was taught to the experimental group. Structural equation modeling was used to model the data and statistical evaluation. The results demonstrated a significant difference between the two groups in MC and LB. The CU significantly improved MC directly, and indirectly through the improvement of LB (i.e., engagement and learning focus, verbal behaviors, and type of activity).


The work is devoted to the issues of risk forecasting in project management systems. The paper proposes to use the analytical capabilities of neural networks of direct propagation. This is an option that allows you to take into account the influence of subjective factors when determining risk in project management. The model of such a network makes it possible to use bifurcation dependencies as a formula for activating synapses. This approach has its difficulties in training a neural network. It allows you to formalize its work in conditions of uncertainty of input signals for individual neurons. A formula for taking into account bifurcation dependencies when using them in neural networks of direct propagation is proposed. The scope of application of such a dependence in the training models of the neural network of direct propagation is shown. This is shown on the example of a project management system, where both the contractor and the customer have a subjective factor. The possibilities of such models for analyzing possible risks both in the creation and in the implementation of projects are shown. At the same time, the risk of losing any factors from among those that lead to the emergence of risk-forming scenarios and events is excluded. This shows how easy it is to take into account the uncertainty in signal activation systems when training a neural network. Such an approach can make it possible to find solutions in a selected area for a wide range of similar problems. However, the requirement for network architecture can be problematic because of its individuality for each type of task. For the selected system, key scenarios have been identified, including subjective ones, which depend on the actual output functions allocated through the work of the trained perceptron. They reflect the risk system in such projects. And we do this in a generalized version, without specification for design systems. The proposed model of a direct propagation network can be extended and specified for a variety of tasks of this type, differing only in the meaning of input signals as logical statements. In this aspect, the material can be of a methodological nature and be applied not only in project management, but also in training systems
