There are created systems and methods for x-ray identification. The systems and methods organize image information to patient information. The method includes acquiring information from a patient for the digital X-ray detector (300, 500) external identification element and a mount holding the patient information within the X-ray detector or an image. The method further includes associating the patient information to the acquired by the X-ray imaging system images and transferring the acquired images together with associated information to a host system when the X-ray detector is connected to the host system.


This article focuses on the development of a theoretical framework for jazz dance in which researchers hypothesized how motif notation concepts from Laban Movement Analysis (LMA) and Language of Dance® (LOD) could be used to help learners understand how the roots and branches of jazz dance styles are related.We began by investigating the Africanist aesthetics of jazz dance to better grasp how each element influences the feel of jazz as it exists within various jazz dance styles. To differentiate between the styles, we deciphered how the Africanist aesthetics blend with Europeanist aesthetics and movement vocabulary to merge into a variety of distinctly American dance forms. Notation-based dance theory offers a unique lens for analytical observation that helps to support theory discussion surrounding the essence of jazz as it is felt in the body. The Africanist aesthetic framework we created provides conceptual tools for comprehending thescope of jazz dance and a movement analysis perspective that might contribute to social, concert, and commercial or entertainment research. We hope this framework proves useful to others in their jazz inquiries by offering fertile conceptualground for jazz dance research and pedagogical development within academic and artistic practices.

PURPOSE: A method of making a thin film transistor is provided to secure the reliability of a pad part by forming a contact hole so as to expose a gate pad and an auxiliary data pad when forming a semiconductor layer. CONSTITUTION: The method of making a thin film transistor is composed of forming a gate line(22) and an auxiliary data line(28) on an insulation substrate(10) and forming a gate insulating film, a semiconductor layer(40) and a resistor contact layer(50) to cover the gate and auxiliary data lines. A resistor contact layer pattern, a semiconductor layer pattern and a gate insulating film pattern are simultaneously formed by etching the gate insulating film, the resistor contact layer and the semiconductor layer. The gate insulating film pattern has the contact hole(36) for exposing the auxiliary data line. A data line(62) is formed which is extended in the first direction perpendicular to the second direction and is connected to the auxiliary data line via the contact hole. A source electrode(64) is formed which is connected to the data line. A drain electrode(66) is formed which is located at an opposite part to the source electrode.


Rewriting, in the narrow sense, is the presentation of works of literature to suit various ideological and poetological ends; it refers to the written process of changing genres. In the broader sense, it includes all forms of transforming a text from one culture or text type to another. In that sense, rewriting places the production and reception of literature within the wider framework of culture and history. Translation is one form of rewriting; it transforms a text written in one source language into another target language. States or their leaders can use rewritings for cultural, political, economical and ideological purposes. J.K. Nyerere used rewriting as a tool for ideological, social and Cultural Revolution. Moreover, he used rewriting as a technique of mobilizing and infl uencing his society towards appreciating religious doctrine and African socialism. This paper examines some of J.K. Nyerere's rewriting contributions into Kiswahili since his country's independence.


Extracting channel state information (CSI) from WiFi signals is of proved high-effectiveness in locating human locations in a device-free manner. However, existing localization/positioning systems are mainly trained and deployed in a fixed environment, and thus they are likely to suffer from substantial performance declines when immigrating to new environments. In this paper, we address the fundamental problem of WiFi-based cross-environment indoor localization using a semi-supervised approach, in which we only have access to the annotations of the source environment while the data in the target environments are un-annotated. This problem is of high practical values in enabling a well-trained system to be scalable to new environments without tedious human annotations. To this end, a deep neural forest is introduced which unifies the ensemble learning with the representation learning functionalities from deep neural networks in an end-to-end trainable fashion. On top of that, an adversarial training strategy is further employed to learn environment-invariant feature representations for facilitating more robust localization. Extensive experiments on real-world datasets demonstrate the superiority of the proposed methods over state-of-the-art baselines. Compared with the best-performing baseline, our model excels with an average 12.7% relative improvement on all six evaluation settings.


Complex processes can be seen as a series of actions, changes, and/or events that are related in different temporospatial manners, and thus are potentially difficult to understand. Optimizing such a process is therefore not necessarily a simple feat, and doing it experimentally may become both time-consuming and expensive. Computer-aided optimization therefore lends itself as a viable alternative, since it can be performed in a relatively short time at a low cost, whilst providing insights into how to improve a process.The work collected and presented in this thesis concerns three different complex processes in the two categories of production systems, and urban environments, all in need of improvements. These three cases have thus been the subjects of a series of studies collected and presented in this thesis, appended as Papers I-IX. For production systems, two cases are presented. The first case is the purification of a polyalcohol at Perstorp AB, the process of which was subject to process-disturbing oscillations that were analyzed and their effects quantified through an in-silico sensitivity analysis, and subsequently reduced by 99.7% via a computer-aided dynamic optimization approach. Secondly, the chromatographic purification of pharmaceuticals has been studied, where optimization techniques were used for the dynamic optimization of the loading phase of a capture step as well as the optimal design of integrated column sequences. In the category of urban environments, blue-green systems for urban flooding mitigation in the city of Malmo have been studied, where a model was developed and then applied for optimal economic siting and sizing of retrofits taking into account implementation and flooding-induced costs. With a 3% decrease in costs, whilst modest, this result shows that the blue-green systems are economical alternatives to consider for mitigating urban flooding.The purpose of this thesis – in addition to improving the three aforementioned processes – is to provide tools, in the form of a procedure and a framework, that can be used to increase the accessibility of computer-aided optimization. The aim is that these tools can be useful to practitioners and facilitate studies, which in turn can be used as a foundation for improving any given complex situation or process. In addition, a summary is presented of the most important parts of an optimization problem and its formulation, and the most relevant optimization approaches to the work presented in this thesis are also summarized and explained. Furthermore, the presented tools are used to describe and analyze the work that has been performed and is presented in this thesis. They are also used to explain how the choices that are made regarding tools for modeling, simulation, and optimization may impact each other, and thus have an interplay. With thesegeneral and generalizable tools, the aim is to contribute towards an increased understanding and thereby accessibility of computer-aided optimization. (Less)

This paper gives a comprehensive evaluation of the solid-phase extraction technique for isolation of chemical warfare agents and related compounds from aqueous solutions. Several factors which may affect the amounts recovered by this method were investigated. These included sorbent type, amount of sorbent, pretreatment of the sorbent, type of eluting solvent, amount of eluting solvent and washing procedures. In addition, the degradation of compounds retained on the sorbent has been evaluated at different temperatures. Among several non-polar sorbents, octadecylsilane (C18) was found to give the highest yields. The amounts recovered depended on the sample volume and the amount of sorbent used. The sorbent may be washed with water after application of the samples in order to remove polar impurities. Methanol and acetone were most effective in eluting the compounds from the C18 sorbent, but isopropanol, dichloromethane, chloroform and diethylether could also be used. In order to prevent degradation ...

. At its best, the emergence debate provides a helpful model of what religion-science scholarship can and should involve. (At its worst it represents the faddishness and bandwagon effects to which our field is also prone.) Those involved in the debate must pay close attention to concrete theories and results in the natural sciences. They rely on the careful conceptual distinctions that philosophers of science draw concerning complexity, novelty, and organization. The resulting views about human mentality and consciousness are tested against these results and checked for their adequacy to the phenomena of human experience. Emergentist theories of nature and personhood have entailments for one's theory of religion and for theological reflection; conversely, theological accounts may constrain one's interpretation of emergent phenomena. In my response to the four symposiasts I draw out these deeper dimensions of the emergence debate.


This paper is presents the dynamic modeling and control system design of a shrouded propeller based on the classical method. The dynamic model has been designed using nonlinear aerodynamic models by VLM (Vortex Lattex Method). The aerodynamic analysis of the model is indispensible for the improvement of its accuracy and for designing the controller. Based on the LTI model of hover, classical SISO control has been used for the stabilization of the vehicle. The controller for hover has been designed using the linear SISO control approach. Further, the control system design has been based on the precise dynamic model for more accurate controller gain selection. The proposed controllers have been presented along with the simulation results. In conclusion, the performance of the proposed approach has first been validated by numerical simulation and then by a series of flight tests.


This paper presents a solution that provides high security for the fast transmission of images through Internet. To reach this goal, a chaos based cryptosystem is implemented using client side and server side technologies. The RSA key pair for encryption and decryption is generated and sent to the server which uses it to encrypt the initial condition and the parameters of the chaotic map. This approach allows us to encrypt the image with the public key and decrypt it only with the private key. Thus the problem of keys management that encounter the chaos-based symmetric cryptosystems is resolved. The proposed method is used to design a suitable web application and the results indicated that our approach provides a fast and secure process for the image transmission.


set of the prey species available to them. They clearly have very strong ideas about what constitutes food, and may eat only marine mammals, for example, or certain fish species. This predisposition to picky eating is evident in captivity, where killer whales consistently refuse unfamiliar food. Similarly, and despite the fact that his keen eye might have picked out differences in the appearance of killer whales from different areas, Scammon had no way of knowing that killer whales have a xenophobic of his observations, Scammon was essentially correct. Killer whales are found in all of the world's major oceans, do feed on prey ranging from herring to blue whales, and – for good reason – inspire fear in their prey. However, it has become clear in the past couple of decades that the killer whale diet story has a twist that Scammon could not have anticipated. Despite the great variety of prey eaten by the species as a whole, individual killer whales often, perhaps always, focus single-mindedly on a limited by Lance Barrett-Lennard


Patient: Female, 67-year-old Final Diagnosis: Cerebral amyloid angiopathy related inflammation Symptoms: Headache, Behavioral Changes • Seizures Medication: — Clinical Procedure: — Specialty: Neurology • Neurosurgery Objective: Rare disease Background: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is an acknowledged syndrome of reversible encephalopathy, also known as cerebral β-related angiitis. It is characterized by brisk progressive higher mental dys-functions, headaches, seizures/epilepsy, and behavioral changes, and is highly responsive to immunosuppressive medications. To quickly and properly determine patients' management plans and prognoses, doctors are left with only CAA-ri-associated behavioral changes and seizures, in addition to a high index of suspicion of the correct diagnosis. Case Report: A 67-year-old woman was presented to the emergency room (ER) with behavioral changes and seizures. Upon screening, the patient was found to have radiological evidence of asymmetrical cortical-subcortical white-matter lesions accompanied by multiple cerebral microbleeds in the background of the negative screening for infectious/neoplastic and paraneoplastic processes. After undergoing a brain biopsy, the diagnosis was confirmed to be amyloid deposition within the inflammatory vessel walls. The patient showed a dramatic improvement after methylprednisolone pulse therapy, plasma exchange, and rituximab maintenance. Conclusions: We encourage and support brain biopsies to confirm highly suspicious CAA-ri atypical cases to initiate early treatment and achieve the best outcome without any further delays.


A computer code (BEMOD) has been developed to describe the behavior of reactor fuel elements during irradiation. BEMOD calculates stresses and strains of a cylindrical sodium-bonded metallic fuel element at several axially distributed points along the element. Growth of the fuel during irradiation is described as the sum of inexorable swelling and compressible breakaway swelling. Inexorable swelling is a linear function of the fraction of fission gas released. The fuel rod is only allowed to expand radially, and fission-gas release is taken to be an empirical function of the fuel expansion only. The pressure acting upon the cladding is either the plenum pressure or the pressure exerted by the fuel in direct contact with the cladding. No friction or trapping of bond sodium between the fuel and cladding is allowed. The creep of the cladding is described by an average temperature and an average hoop stress, and irradiation growth of the cladding is neglected. The behavior of the fuel element is described under steady- state conditions, but the code also calculates the stresses and estimates strain changes for an accidental overpower or flow-coast-down. As an application, the BEMOD code is used to calculate the influence of several design parameters on cladding strain as a function of burnup of the EBR-II driver fuel. These variables are plenum volume, linear power, smear density, gas release, and cladding strength.

Conclusion HP infection may be by reducing gastric mucosal expression of tumor suppressor gene p27 protein level sinduced gastric mucosal carcinogenesis.


In the last decades, an intensification in the animal production and an increase in the size of the animal production units have been produced in the developed countries (only in the EU-27, more than 1500 mill. tonnes of animal manure are produced every year) (Holm-Nielsen et al., 2009). This fact implies a great generation of animal manures that can constitute an environmental risk, if not managed properly. Nowadays, anaerobic digestion is one of the methods that is gaining interest to manage the wastes generated by livestock production. This treatment transforms organic wastes into two products: a source of renewable energy (biogas) and a potential fertiliser, the digested material (digestate). However, some characteristics of the digestate (phytotoxicity, viscosity, odour, etc.) make it difficult its direct application in agricultural soils (Abdullahi et al., 2008). One option is to separate the digestate into a liquid and a solid fraction, the latter can be composted in order to obtain valuable and marketable end-products for agriculture (Møller et al., 2006). The co-composting of the digestates obtained by anaerobic digestion of animal manures, with agricultural residues, such as vine shoot pruning (VP), could constitute an efficient method to manage these wastes, not only to reduce the potential environmental problems associated, but also to recycle them. The compost obtained is a stabilised organic material that contains humic-like substances, which can be safely used as organic amendment in agricultural soils. Therefore, the aims of this work were to study the co-composting process of the solid fraction of a digestate, obtained from the anaerobic digestion of cattle slurry, with vine shoot pruning (VP), and to evaluate the characteristics of the end-products obtained.


A scalable and reconfigurable architecture for accelerating classification using Radial Basis Function Neural Network (RBFNN) is presented in this paper. The proposed accelerator comprises a set of interconnected HyperCells, which serve as the reconfigurable datapath on which the RBFNN is realized. The dimensions of RBFNN that can be supported on implemented design is limited due to the fixed number of HyperCells. To resolve this limitation, a folding strategy is discussed which provides a generic hardware solution for classification using RBFNN, with no constraint on the dimensions of inputs and outputs. The performance of RBFNN implemented on network of HyperCells using Xilinx Virtex 7 XC7V2000T as target FPGA is compared with software implementation and GPU implementation of RBFNN. Our results show speed up of 1.91X-15.94X over equivalent software implementation on Intel Core 2 Quad and 1.33X-14.6X over GPU (NVIDIA GTX650).


Following the contributions of Aran,1Charcot,2Marie and others the essential pathologic lesions responsible for the various myopathies have been diligently studied. Still these attempts have resulted in few fruitful rewards. At present, with the usual standards of diagnosis, accurate determination of the etiologic factors in most of these cases taxes the diagnostic acumen of the best trained clinicians. It seems desirable, therefore, to study the various myopathies, from a metabolic as well as from a clinical point of view, with the aim of evolving observations that may have diagnostic and prognostic applications as well as distinct therapeutic value. The advent of amino acid therapy in the treatment of myasthenia gravis, primary muscular dystrophy and secondary muscular atrophy has opened such vast and comparatively fertile fields of scientific endeavor that it appears that the biochemical investigation of these cases should result in many interesting and important contributions, particularly


Five Chumash rock art sites in the Wind Wolves Preserve, California, were examined using portable Xray
fluorescence analysis in order to compare red pigments used, differentiate between pigments and
painting events, and discuss the implications of this information. The results showed that the technique
was successful in identifying different pigments and that multiple pigments were used within each rock art
panel and within individual elements. These results indicate the presence of multiple artists or episodes of
retouching over time, and potentially a less exclusive role for rock art than some have suggested
previously.


Precision pneumatic drills is used in seed singling and it provides a decrease in the labour in thinning operation. Vacuum and peripheral velocity of seed metering device are two important factors which affect the quality of seeding. Hole diameters and numbers of holes on rotate seed metering plate are determined according to the physicomechanical properties of seeds and the distance of seed in the row. The aim of this research is, to determine the sultable vacuum level, hole diameters and peripheral velocity of rotate metering plate dev ı ce for corn, sunflower, soybean, covered and uncovered sugarbeet seeds. In this study, proper forward speed of the precision pneumatic drills, distance of seed in the row and physicomechanical properties had been found for the mentioned seeds. Constructional values such as the diameter of wheel, transmititon ratio and diameter of rotate metering plate had been used to calculate linear velocity of rotate metering plate. The hole diameters were 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5 and 7 mm; vacuum levels were -4, -6, -8, -10, -12 and -14 kPa; the linear velocity of rotate metering plate were 0.25, 0.38, 0.55 and 0.79 m/s in trials. As a result of this, the seeds had been holded in the significant hole diameterson the all vacuum and all linear velocity. In addition to this Besides the seeds could be holded as a single seed which is smaller than the hole diameters generally at the high vacuum level and low linear velocity 'eve!, however the seeds could not be holded in low vacuum levels and high linear velocities. The amount of single seeds decrease when the bigger hole diameter was used, since the seeds either holded multiply or run to the vacuum line.


The article is devoted to the problem of forming the communicative culture of future teachers in the process of project teaching in higher educational establishments. Methodological approaches to the definition of the concept of "communicative culture" are analyzed, its qualitative characteristics are determined and examples of discussions in the scientific environment on the characteristics of this phenomenon are given. The authors claim that the component of communicative culture is communicative competence, which in the educational process of higher education largely determines the quality of training of future teachers for future professional activities. The article gives the hypothesis that project activities may be one of the effective means of forming both communicative culture and communicative competence, which at the present stage of training graduate students is considered the most effective and rational in domestic and foreign pedagogy. In order to test the hypothesis, the results of the diagnostic stage of the experimental study conducted during the training of future foreign language teachers in higher educational establishments are demonstrated. The analysis of the results of the experiment allowed us to conclude that project teaching is defined by both students and teachers as one of the effective means of forming the communicative culture of future graduate students. Its significance is determined by the fact that it allows students to thoroughly analyze scientific information, use a creative approach to learning materials, promote the formation of skills to listen to others, respect alternative opinions, model and solve cognitive, life and social situations.


The performance of a miniature gas turbojet engine for powering an aircraft is investigated experimentally. The engine is fueled by propane gas to avoid the difficulty of atomization, evaporation, and combustion of the liquid fuel in a small combustor. The operating characteristics of the engine are attained through measurements of temperature, pressure, thrust, volumetric flowrate of air, fuel and lubricant consumption rates, rotation speed of shaft, and exhaust gas composition. Nomenclature A/F air/fuel ratio EGT exhaust gas temperature F thrust (lb) Ν rotation speed of compressor (rpm) Pg compressor gauge pressure (bar) Qin volumetric flow rate of incoming air (1/min) φ equivalence ratio To have a miniature gas-turbine for powered radio-control flying models has long been a dream of modellers. Such a miniature gas-turbine engine was successfully developed in 1991 (Cherry, 1993). It was fueled by a kerosene-type oil and has encountered several drawbacks, such as underpower, starting problems and flame-out. To date, at least ten such engines have matured, with maximum thrust ranging from 30 to 100 Newtons (Cherry, 1995). Among them is the JPX T240 engine (JPX, 1993 and Figs. 1 and 2). It is fueled by propane gas. To understand its combustor characteristics, Ho et al. (1995) have set up a test facility for small annual combustors. It includes a single-stage centrifugal-flow compressor consisting of a twelve-blade impeller and a seventeen-vane difliiser, as described by Treager (1979). During the tests, the compressor reaches about 80 percent efficiency (Yang, 1995), with a compression ratio of 2.3 to 1 at 120,000 rpm. Its radial inflow turbine wheel has 11 blades and 20 guide vanes to turn the hot stream into the turbine nozzle area, which has 9 blades implanted on the exit of the combustor inner liner. Inlet air flowrate is shown in Fig. 3. The incoming airflow is in the range 0.1 to 0.25 Mach. Compressor rpm plotted against compressor gauge pressure is depicted in Fig. 4. Fig. 5 indicates equivalence ratio changes. Fig. 6 displays variations of lubricant consumption rates. Since the lubricant is pressurized by compressor outlet airflow, its flowrate is proportional to the rotational speed of 1 Researcher 2 Associate Researcher 3 Technician 65


We are concerned with the calculation of macroscopic linear thermo-electro-elastic properties for polycrystalline and composite materials. Due to the complexity of the coupled electro-mechanical field equations in 3D, in most cases exact solutions are impossible. Therefore we apply the well-known Effective field and Effective medium approximation. This can now be done since recently explicit results for the fully coupled Eshelby tensors became available. We present shortly the basics of the theory and illustrate it by numerical evaluations. The resulting effective material constants of piezoelectric ceramics depend non-monotonously on the degree of poling, and the properties of composites may strongly differ from predictions on the basis of simple rule of mixtures.

Plasma membrane vesicles (PMVs) were prepared by phase partitioning from microsomal fractions of either sink or source leaves of sugar beet (Beta vulgaris L.). The purity, the internal volume, the sidedness, and the sealingness of PMVs prepared from sink leaves did not differ from those measured with PMVs from source leaves. Yet, in response to an imposed proton motive force, PMVs from source leaves accumulated about 4-fold more sucrose than PMVs from sink leaves. The developmental stage did not affect the uptake of glucose and valine in PMVs prepared from leaf tissues. It was concluded that the sink/source transition is accompanied either by the incorporation into the plasma membrane of leaf cells of proteins mediating proton-sucrose cotransport, or by their activation. N-ethylmaleimide and a polyclonal ascitic fluid directed against the 42-kD region of the plasma membrane containing a putative sucrose carrier inhibited the uptake of sucrose in PMVs from source leaves, but not in PMVs from sink leaves. Sodium dodecyl sulfate gel electrophoresis and western blot suggested that the 42 polypeptide was more abundant in the PMVs from source leaves than in the PMVs from sink leaves. The development of the leaves in plants is characterized by a transition from a heterotrophic stage in young leaves to an autotrophic stage in mature leaves. The different aspects of this topic have been recently reviewed (27). Young leaves import the sugars that they need for growth, whereas mature leaves will export the excess of sugar they produce to other part of the plants. Apart from its central role in leaf development, this transition provides a straightforward system to compare sink and source tissue without dealing with the complications introduced by the study of different organs (27). The sink/source transition of the leaf is a highly integrated process beginning when the leaf has reached about 35% final lamina length, and proceeds from the tip to the base (7). The transition is made possible by a series of changes affecting both metabolism and transport. From the metabolic point of view, the cessation of import does not require achievement of positive carbon balance and is not the direct result of export initiation (26). In contrast, the beginning of export requires the development of metabolic processes able to provide sucrose for export. In sugar beet, accompanying the import-export transition is an increase in photosynthesis, an increase in the relative proportion of 14CO2-derived soluble compounds, and a change in


For finding out the effects of Re on microstructure stability in a new Ni-based superalloy,the microstructure of aging sample was observed by Scanning Electron Microscope(SEM),and the new precipitated phase after long term aging was analyzed by Transmission Electron Microscope(TEM).The experimental results show that the microstructure of the four alloys after heat treatment includes γ,γ′,MC carbides and M23C6 carbides.Needle M23C6 precipitates appear in dendrite core when Re content is 4wt % in the alloy.The stability of microstructure is weakened and the growth rates of γ′ phase slow down with the increasing of Re content.There are σ phase precipitates after aging for 1 000 h at 900 ℃ when Re content is 4wt %,so that the Re content should be lower than 4wt% in the alloy.


Extract volatile matter was extracted from stem and leaves of Coriandrum sativum L.by steam distillation and drip-rinsing process respectively.Biologial activity of antifeedant effect on Pieris rapae L was tested with extraction of coriandrum sativum L..The results showed that extracts of Coriandrum sativum L.had strong antifeedant effect on Pieris rapae 3-instar larvae,and antifeedant effect on Pieris rapae 3-instar larvae increased with the concentration of the extracts of Coriandrum sativum L,which antifeedant rate on Pieris rapae 3-instar larvae reached 100.0% at 72 h in the dilution 50 times,100 times,200 times and 400 times.The antifeedant effect was relatively weak at 800 times and the,antifeedant rate reached 66.7%.

The measurement methods of N-niroso compounds in beer mainly covered heat energy analyzer method, gas chromatography and HPLC method. (Tran. by YUE Yang)


Background:  Professional soccer players are susceptible to amyotrophic lateral sclerosis. Strenuous physical activity has been associated with persistent inflammatory conditions and elevation of systemic cytokine levels, which could contribute to the vulnerability of these athletes. To investigate changes induced by playing soccer in the systemic profiles of growth factors and of the principal cytokines involved in the inflammatory response, we compared the serum concentrations of these factors in Italian professional soccer players and sedentary subjects. We also investigated the effects of the sera on primary cultured motor neurons in relation to their cytokine and growth factor content.


Many of us want to develop more interesting papers that come to grips with more important problems. How, for instance, should we go about studying a cluster of young women who developed cancer because they worked with inadequate protection against radioactive materials and later catalysed revolutionary changes in industrial hygiene (Clark, 1997)? How can we turn financial and ecological catastrophes into natural experiments to shed light upon the resilience of effective leaders and organizations? Such cases present exciting opportunities for study but also challenges to theory development and methodological rigor. The objective of this Professional Development Workshop (PDW) is to explore the opportunities as well as the challenges associated with studying unique events such as disasters, crises, and environmental accidents, and to bring like-minded scholars together to build community who are interested in exploring how to develop theoretically sound and methodologically rigorous research based on events which are without precedent and may remain without a future recurrence.


SU(5) gauge theory with massless left-handed fermions in the representation 5+15+40+45* (QUD) may have a bound-state S-Matrix that, uniquely, contains the asymptotically unitary Critical Pomeron and which might also reproduce the full Standard Model. If so, QUD would provide an underlying unification for the Standard Model in which very similar massless fermion anomaly dynamics is responsible for the physics of the strong and electroweak interactions and all particle masses are generated dynamically. The color sextet quark sector, responsible for both electroweak symmetry-breaking and dark matter in QUD, is predicted to produce large cross-section effects at the LHC, with the pomeron as a vital diagnostic - via TOTEM/CMS and FP420.
In this talk, the multi-regge construction of high-energy QUD amplitudes is outlined as is, briefly, the LHC pomeron physics. Surrounding motivational issues (particularly outstanding QCD problems) and consequences are also discussed. The S-Matrix anomaly physics is conceptually and philosophically radical with respect to the current theory paradigm. As a consequence, QUD could provide a welcome way out of the current ``Crisis in Fundamental Physics'' with, potentially, it's novel physical applicability resolving a variety of Standard Model and, perhaps also, cosmology problems - it has zero vacuum energy.


The dynamics of the luminescence decay from self-assembled germanium islands embedded in crystalline silicon has been studied for temperatures varied between 16 K and room temperature. We separate the time scale for various dynamical processes by time-resolved emission spectroscopy and identify a characteristic time scale of Auger recombination processes around 10 ns largely independent on temperature, while two slower decay components appear on time scales around 1μs and 10μs, respectively, at low temperatures.


Background Cognitive functions are supported by brain networks and they are highly dependent on the integrity of long white matter tracts that mediate the information flow between such distant cortical areas. Brain damage in multiple sclerosis (MS) may produce cognitive impairment by preferentially damaging these tracts, thereby impairing brain synchrony. Auditory amplitude modulation following responses (AMFR), are oscillatory steady-state responses to rhythmic auditory stimuli that indirectly measure brain synchrony. Objective To study the effect of MS lesions in brain synchrony and its relationship with cognitive function. Methods We assessed the correlation between cognitive performance, as assessed with the brief repeatable battery–neuropsychology (BRB-N), and the AMFR in a group of 27 MS patients and 22 healthy controls. Results The maximal AMFR frequency – but not the amplitude – in the 30–60 Hz range was lower in patients with cognitive impairment than in patients with no cognitive impairment or the healthy controls (39.79 Hz, 43.85 Hz, and 43.84 Hz, respectively, P < 0.05). Indeed, the frequency of the AMFR was negatively correlated with the scores obtained in verbal memory, attention, and executive function. The multiple regression analysis indicates that the AMFR was the best predictor of the BRB-N scores after controlling for potential confounding factors such as age, education, disability, and years of disease evolution. Conclusions These results suggest that the loss of synchronization in different central nervous system (CNS) pathways caused by demyelinating lesions might involve both the slowing of brain oscillatory activity and less efficient cognitive processing.


This paper analyzes the stability of shield-driver circuits (SDCs) applied to the measurement of remote signal sources (such as bioelectric signals) and then proposes design ideas to guarantee it. According to the performed analysis, there are at least two factors that explain the potential instability of the SDC: 1) a high order of the SDC transfer function and 2) the parasitic inductance of the interconnecting cable. The former makes the circuit unstable for intermediate values of the output resistance RS of the signal source, whereas the latter makes the circuit unstable for low values of RS. These theoretical predictions are experimentally validated using several commercial operational amplifiers.

Oestrous cycle, gestation, parturition, litter size, lactation and sexual maturity were studied in a captive colony of the Australian murid P. novaehollandiae. The pattern of reproduction is similar to that of other murids, although oestrous cycle (6.0 ± 1.26 days) and gestation period (31.5 ± 0.96 days) are longer than those in the laboratory rat and mouse. Changes in the external appearance of the vagina were too inconsistent to identify stages of the oestrous cycle, but were of use in determining the stage of pregnancy or lactation. Parturition took place during the light phase of the day-length regime, with post-partum oestrus during the following dark phase. Weight changes in pregnant and lactating females were considered. The average litter size was 4.0 ± 1.03 with a range of one to six. Oestrus was inhibited during lactation and recurred about 24 days after parturition. Sexual maturity was earlier in females (13 weeks) than in males (20 weeks).


In this article, author and artist Meena Murugesan analyzes their creative process and research in the making of Dravidian Futurities, a multi-channel video installation with live performance. Methodologies of auto-ethnography, visual aesthetics, embodied movement practices, Tamil historiographies, queer futurities, caste analysis, and poetics are applied to treat the issues at hand. Dravidian Futurities draws connections between communities of South Indian and Sri Lankan Shudra and Dalit caste backgrounds, Dravidian, and Afro-Indian peoples, depending on the historical era examined. As someone of the Shudra caste, the author draws connections between agriculture, land, and earth, as being rooted in Shudra identities, and in opposition to brahminical systems. Therefore, the movement forms of somatics, improvisation, and nature-based embodiment practices are investigated as possible embodied inroads to grapple with caste within brahminized bharatanatyam. Notions of futurity and place-making are unearthed from the depths of the Indian Ocean with a hypothetical sunken landmass called Lemuria or Kumari Kandam that might have once connected South India, Sri Lanka, and Madagascar. Dravidian Futurities also dreams into existence this speculative landmass as a possible utopia we might co-build, similar to that which Dalit mystic saint Guru Ravidas imagined five hundred years ago with Begumpura ("land without sorrow") as a casteless, stateless utopia.


Gas condensate well has unique reservoir characteristics and ups and downs in well behaviour affect the production rate significantly. A proper optimization can reduce the operating cost, maximize the hydrocarbon recovery and increase the net present value. Well level optimization can be achieved through optimizing well parameters, such as wellhead, tubing size, and skin factor. All of these factors have been investigated using a real field of Thrace Basin and PROSPER simulation program. The history matching data are validated to identify the future performance prediction for the same reservoir deliverability following the period changes. Therefore, predicted results are compared and validated with measured field data to provide the best production practices. Moreover, the results show that the skin factor has a large influence on the production rate by 45% reduction. The reduction in the reservoir pressure declines the production rate dramatically resulted in 70% decline. While manipulating the wellhead pressure shows minor decline compare to tubing size that does not show any significant change to production rate.


Comrade MAO Ze dong proposed the idea of "Love our nation, love our people, love labor, love science and love public property", which provides abundant connotations. The idea has great realistic significance in the process of advancing the present theory of "Managing state affairs with morals". First of all, it benefits the whole society with their right evaluation of the social function of morals, and with their attention to and the enhancement of moral construction of the whole society, thus providing the nation with the proper management of the relationship between "Managing state affairs with law" and "Managing state affairs with morals"; Secondly, it benefits the nation in the adjustment of the social relationship, especially that of the moral interests; Thirdly, it benefits the people in the enhancement of the education of scientific outlook on life, on value and on morals. Hence, it benefits our nation in the improvement of the Party's work style and the changing of the general mood of society.


The purpose of this paper is to provide an alternative perspective and a process __ a frame and flow, as leveraging component for the development of high performing teams in many organizations and even in the software industry. The first part includes a statement with a reflection on the concept of team, a comparative review of the characteristics/qualities/benchmark of high performing teams (HPT) and the processes to build and develop them. It ends with an inference that these processes of developing HPT are drawn from behavioral and conventional mindsets of team development. The next part proceeds to identify the crucial need to reflect on the mindset underlying team development in the context of the software industry in the information age, one that calls for an alternative frame and flow to develop teams, the option that is brain-based and holistic. The last section offers a perspective __ again, a frame and flow __ called whole brain literacy (WBL) approach as one way to leverage team development enabling participants to become high-performing teams and citing projects and action researches where these have been used as part of the process interventions with positive results and outcomes.


Introduction Preanalytical conditions are critical for blood sample integrity and poses challenge in surveys involving biochemical measurements. A cross sectional study was conducted to assess the stability of select biomarkers at conditions that mimic field situations in surveys. Material and methods Blood from 420 volunteers was exposed to 2 – 8 °C, room temperature (RT), 22 – 30 °C and > 30 °C for 30 min, 6 hours, 12 hours and 24 hours prior to centrifugation. After different exposures, whole blood (N = 35) was used to assess stability of haemoglobin, HbA1c and erythrocyte folate; serum (N = 35) for assessing stability of ferritin, C-reactive protein (CRP), vitamins B12, A and D, zinc, soluble transferrin receptor (sTfR), total cholesterol, high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), tryglicerides, albumin, total protein and creatinine; and plasma (N = 35) was used for glucose. The mean % deviation of the analytes was compared with the total change limit (TCL), computed from analytical and intra-individual imprecision. Values that were within the TCL were deemed to be stable. Result Creatinine (mean % deviation 14.6, TCL 5.9), haemoglobin (16.4%, TCL 4.4) and folate (33.6%, TCL 22.6) were unstable after 12 hours at 22-30°C, a temperature at which other analytes were stable. Creatinine was unstable even at RT for 12 hours (mean % deviation: 10.4). Albumin, CRP, glucose, cholesterol, LDL, triglycerides, vitamins B12 and A, sTfR and HbA1c were stable at all studied conditions. Conclusion All analytes other than creatinine, folate and haemoglobin can be reliably estimated in blood samples exposed to 22-30°C for 12 hours in community-based studies.


In order to avoid fatigue driving, the driver fatigue detection technology is studied by extracting facial fatigue feature parameters. Use the optimized SSD to extract facial features, use PFLD to detect key points of the face, and detect the key points and spatial attitude angles of the eyes, mouth, and head of the face; calculate the face fatigue feature parameters based on time series The matrix is input to GRU for fatigue driving detection. Compared with other eight methods in the case of low computing power, it has a high accuracy rate and detection speed, which meets the needs of the fatigue driving detection system.


To search for warm-hot intergalactic medium (WHIM), a small satellite mission DIOS (Diffuse Intergalactic Oxygen Surveyer ) is planned and a specially designed four-stage X-ray telescope (FXT) has been developed as the best fit optics to have a wide field of view and a large effective area. Based on the previous works such as the design of optics and replica foil mirror fabrication, we made the demonstration model of the FXT, which has a set of four-stage mirror supported by alignment plates to reduce alignment errors between different stages. On the selection of mirror surface metrial, we tried to increase the reflectivity of gold or platinum replica mirror at low energies. We are also trying to make Ni replica mandrel having the shape of four different cone angles for developing a full or partial shell of four-stage mirror formed in a same substrate. We describe the expected performance and alignment procedure of the demonstration model, the present status of the selection of mirror surface material and the development of Ni mandrel.


CWM(Coal Water Mixture) is a mixed fuel that consists of coal, water and additives. The main advantages of CWM are reducing the oil consumption and the air pollution materials such as flyash, dirt, and . This paper presented a case study for the economic feasibility analysis of changing an existing coal-oil power plant to a CWM power plant. The economic analysis of changing a coal-oil power plant to a CWM power plant was based on the total annual incremental costs of two power plants. We found that this project was economically and environmentally acceptable.

This paper examines the impact on Brazilian stocks following American Depositary Receipts (ADRs) listing in the U.S. stock markets. Evidence suggests that a systematic change has taken place in the post-listing period as the multivariate variance ratio statistics have significantly decreased if compared to the pre-listing period, which indicates a move toward a more efficient domestic stock market. This empirical evidence is robust to the use of dollar and local currency-denominated returns. These results add to the literature that finds evidence on changes in domestic volatility and abnormal returns around listing dates.


Abstract The commercial production of photographic printing papers was undergoing significant international change and development during the last two decades of the nineteenth century. In Australia the shift to commercial photographic papers was made possible by the development of locally manufactured goods, produced mainly in Melbourne, Victoria and Sydney, New South Wales, and subsequently distributed throughout the other colonies.


Due to the mine shaft pipeline installation without anti-bending beam which fixed anti-bending device, we analyzed the disad-vantages of the traditional anti-bending device, and designed a new type of anti-bending device. The new anti-bending device has the ad-vantages of strong ability of resisting radial deformation, easy manufacture, convenient installation and low investment.

Photoacoustic imaging relies on generation of ultrasound waves from optically absorbing structures. The ultrasound produced in photoacoustic imaging can be analyzed by methods developed to analyze ultrasound backscatter signals for ultrasound tissue characterization, but the interpretation of the analysis is based on the physics of photoacoustic wave generation. In the absence of exogenous absorbers, blood is one of the dominant optically absorbing tissues. Hemoglobin in red blood cells is the main endogenous chromophore in blood. The spatial distribution of red blood cells in tissue determines the spectral characteristics of the ultrasound signals produced. We are interested in cancer treatment monitoring. Tumor blood vessels have distinct organizational structure compared to normal blood vessels: normal vessel networks are hierarchically organized, with vessels that are evenly distributed to ensure adequate oxygen and nutrient delivery. Tumor vessels are structurally different: they are torturous and hy...


− The aim of this study is finding the optimal design parameters and the optimal operation variables of a reactive distillation column. Different from steady state optimization, dynamic optimization makes it possible considering operation ability as well as design problems at process design step. For performing dynamic optimization, dynamic simulation should be done first. If dynamic simulation is already finished, dynamic optimization can be performed with less effort than that of dynamic simulation.Reactive distillation systems involving reaction and separation in a single unit have the potential to reduce capital and operating costs, particularly when reaction have conversion constraint or when azeotropes exist making conventional separation difficult and expensive. This study here present work on the continuous distillation process, the homogeneous catalyzed esterification of methanol and acetic acid, the synthesis of methyl acetate. Based on an equilibrium stage model of a reactive distillation column a dynamic optimization problem was formulated and solved. And the results were verified by performing dynamic simulation and showing the variation of conversion and purity as the variation of the operation variables. As the results of dynamic optimization, this study found optimal feed ratio, reflux ratio and reboiler duty of this system. And as this study applied it to dynamic simulations the dynamic characteristics of a reactive distillation column are showed under optimal operating condition.


This paper reveals the social and cultural context by using Critical Discourse Analysis on intertextuality relationships in translations that use slang as an equivalent even though the source text, English, is not slang, and analyzes the translation with an interpretive translation approach related to the recontextualization of the present meanings. Due to the use of slang in the target language. This is a qualitative descriptive study with a case study approach. Translation at the level of intertextuality allows the existence of equivalents that reflect the collective identity of certain social groups. This equivalent has the potential to become a new, unusual and different equivalent from the equivalent that has traditionally existed so far, although it still has an element of accuracy that represents the message from the source language. Translating text in terms of intertextuality requires careful interpretation because it refers to the recontextualization of the meaning in the target language which tends to be different from the source language. Translation using slang is a form of recontextualization because it contains elements of the context of different social and cultural realities.


Surface tension of molten Ni and Ni-Co (5 and 10 mass fraction) alloys was measured at the temperature range of 1773~1873 K using an improved sessile drop method with an alumina substrate in an Ar+3%H2 atmosphere. The error of the data obtained was analyzed. The surface tension of molten Ni and Ni-Co (5 and 10 mass fraction) alloys decreases with increasing temperature. The influence of Co on the surface tension of Ni-Co alloys is little in the studied Co concentration range.


Carbonaceous films with metallic luster have been prepared by pyrolytic chemical vapor deposition on the inside surface of a quartz tube at 1000 °C using hydrocarbon including oxygen atoms such as phenols as raw material. The x‐ray diffraction, electrical conductivity, thermoelectric power, and electron‐spin‐resonance (ESR) characteristics of the films heat treated to between 1000 and 2800 °C have been examined. These results indicate complete graphitization of the films by the heat treatment. The three‐dimensional ordering of crystallites in the films and increase in the electrical conductivity have proceeded in the range 2000–2200 °C. The concomitant fall in the thermoelectric power in the same range suggests the contribution of two carriers (holes and electrons). The increasing rate of g shift has been also enhanced in this range. The unusual broadening in the ESR linewidth has occurred around the temperature where a localized center appears and seems to be caused by scattering of mobile charge carriers at the localized centers.


Gellan gum is a kind of microbial polysaccharides. Because of its excellent stability and suspension effect,it is used widely in liquid milk products. The research focuses on application characteristics of gellan gum,especially a high acyl gellan gum,in liquid milk products. Based on China's dairy industry facts,this paper studies the properties of gellan gum and how to scientifically use it,in order to promote application levels of gellan gum in liquid milk.The experimental results showed that: 1The more time of gellan gum solution is maintained at 90℃,the more decrease of elastic modulus and viscosity will be. 2 Gellan gum elastic modulus and viscosity were decreased with increasing of the temperature of pasteurization. 3If the gellan gum dispersed in water of different temperatures it will swell and in 75℃ will go to extreme and showed that the highest viscosity. If temperature of the water used continue to raise,the viscosity start to decline. 4With the increase in the number of reflux,the elastic modulus and the viscosity will decrease obviously.Conclusions: In the actual production, the heating of gellan gum should be reduced as much as possible.Sterilization parameters should be, based on the products category and ensured commercial sterilization, the combination of lower temperature of sterilization and the shorter time of sterilization. For the pasteurized products,sterilization in 75℃ was best with gellan gum suspending very effectively.


Hybrid anion exchange resin containing hydrous ferric oxide (HAIX-Fe) was used in column tests to remove phosphate (PO4) from fresh urine, hydrolyzed urine, and anaerobic digester filtrate, and subsequently recover PO4 as struvite (MgNH4PO4·6H2O) or potassium struvite (MgKPO4·6H2O) via precipitation in the spent regenerant. The recovery of PO4 using the two-step adsorption–precipitation process was compared with direct precipitation in urine and anaerobic digester filtrate considering chemical requirements for precipitation and mineral purity. Following the saturation of HAIX-Fe resin with PO4 from urine and anaerobic digester filtrate, up to 95% of the PO4 was desorbed using caustic brine during the regeneration phase. The spent regenerants were more concentrated in PO4 than the original urine and anaerobic digester filtrate due to recycling of the regeneration solution. Precipitation in the spent regenerants and original wastewaters (urine and filtrate) yielded 96.7–99.8% PO4 recovery as struvite or potassium struvite. Direct precipitation in fresh urine and hydrolyzed urine was more efficient than precipitation in the corresponding spent regenerants based on lower chemical requirements. Precipitation in the spent regenerant from HAIX-Fe resin saturated with PO4 from anaerobic digester filtrate produced a higher purity mineral than direct precipitation in the anaerobic digester filtrate.


Objectives:The study had four major objectives: (1) to identify the types of qualifications,certifications and accreditations offered by Australian life coaching schools; (2) to provide an overview of the advertised content and cost of life coach training courses; (3) to identify how life coaching schools differentiate between life coaching and mental health treatment; and (4) to explore the marketing statements made about courses, schools, owners and trainers.Design:This study employed a qualitative research design in which information on Australian life coaching school's were drawn from their websites. Emergent themes were coded and analyses conducted on the basis of those themes.Methods:Following an internet search, the emergence of broad categories and themes related to the aims of the study were documented, leading to the identification of a group of core categories and a final process of comparison between schools.Results:Of the 14 Australian life coaching schools identified, six claimed to be International Coach Federation accredited and five offered courses under the Australian Qualifications Framework. Cost for courses varied between A$1070 and A$9990. Nine of the 14 schools made no explicit distinction between life coaching and treatment for mental health issues, and one school stated that life coaching could be used to deal with anxiety-related problems. Self-promotional statements about teachers and owners varied greatly from claims of university affiliations to prior experience as a cordon bleu chef. The claims made as to the earning potential of life coaches were not unrealistic.Conclusions:In general, the self-promotional statements of the Australian life coach training industry were flamboyant but only a few were considered outrageous. Recommendations made include that schools become Registered Training Organisations, that students check the claimed accreditations, academic affiliations of schools, and validity of qualifications and credentialing, and that schools make explicit the distinctions and boundaries between mental health treatment and life coaching.


To a reduced plane curve singularity with r branches there is associated its semigroup, a subsemigroup of Zr⩾0. For an irreducible curve singularity, the description of its semigroup in terms of its set of generators is well known. For a reducible curve there exists a combinatorial description of the semigroup. The semigroup of a plane curve singularity with several branches is described in terms of the minimal set of generators constructed in a natural geometric way.


Gobies are generally small fishes which play important roles in estuarine ecosystems, yet little attention has been paid to their life-history traits in the western Pacific region. In the present study, we explored the reproductive traits of the dwarf gobies Pandaka trimaculata and P. lidwilli by examining populations in a subtropical estuary on Okinawa-jima Island, Japan, over 15 months. The Okinawan populations of both species shared similar reproductive traits. Pandaka trimaculata and P. lidwilli exhibited early female maturation at minimum sizes of 8.8 mm and 9.4 mm standard length, respectively, which indicate that populations of the Pandaka species in the subtropical region represent some of the smallest fishes in the world. However, they also had high relative body sizes at maturity relative to the attained asymptotic standard lengths, ranging from 75.8% to 80.4%, which suggests that their populations are vulnerable to negative impacts. Both species also had prolonged spawning periods, extending from February to November in P. trimaculata and from January to October in P. lidwilli, indicating that these local populations have a high potential for maintenance and resilience. Their spawning periods, sizes at maturity and fecundities varied among seasons and latitudes, possibly due to low water temperatures affecting the relative allocation of energy to growth and reproduction. Such plasticity of life-history traits in these small fishes indicates that they would be suitable models for understanding the evolution of life-history strategies and monitoring the responses of organisms to climate change.

Objective The purpose of this study was to investigate the relationship between oxygen consumption (VO 2) on the recovery from incremental maximal exercise and the levels of the blood lactate (HLa), glucose and alanine metabolism.Methods The VO 2,HLa and plasma alanine were obtained using a modified version of Bruce's protocol until 30 min after exhaustion for 10 men.Results The VO 2 on recovery had returned to the pre-exercise, but the HLa concentrations and plasma alanine were significantly increased from rest to maximal exercise, and were significantly decreased thereafter, but remained above resting values for 30 min after maximal stage.Conclusions We conclude that oxygen consumption after exhaustive maximal exercise is related to glucose resynthesis through alanine metabolism, as compared with that from lactate metabolism.


Random regression models with simultaneous and recursive links between phenotypes for milk yield and somatic cell score (SCS) on the same test-day were fitted to Canadian Holstein data. Heterogeneity of structural coefficients was allowed for across (the first 3 lactations) and within (4 days in milk intervals) lactation. Model comparisons indicated superiority of simultaneous models over recursive and standard multiple-trait models. A moderate heterogeneous (both across and within lactation) negative effect of SCS on milk yield and a smaller positive reciprocal effect of SCS on milk yield were estimated in the most plausible specification. Estimates of genetic parameters on a daily basis differed while rankings of bulls and cows for 305d milk yield, average daily SCS and milk lactation persistency remained the same among models. No apparent benefits are expected due to fitting causal phenotypic relationships between milk yield and SCS in the random regression TD model for genetic evaluation purposes.

ABSTRACT With emerge of smart navigation, the secure communication issues have drawn extensive attention on maritime agendas between ships or with the shore. This paper presents a chaotic secure communication scheme by using observer design for maritime navigation and transportation systems. The proposed scheme involves three key factors: chaotic encryption, state observer, and chaotic decryption. The chaotic system, as the encryption keys carrying confidential information, will be sent from transmitter to the receiver through a public channel. It is obvious that the fewer signals are transmitted on the public channel, the higher security of the communication system is possible. A state observer is designed to estimate all system states when only partial states are detectable on the public channel. The robust observer gain is implemented in terms of linear matrix inequality (LMI) for convex optimization. The process of information encryption and recovery has been discussed in detail. From the simulation results, it is found that the observer-based method can robustly estimate full state variables by using system output signals with LMI optimization. Based on these updated states with the the state observer, the original information is accurately recovered for safe navigation of vessels with reliability and efficiency.

His attitudes towards the author of the text, then a conclusion in which we explained the most important results of the research.


In this article I attempt to show that an enhanced awareness of the rhetorical perspective toward law is a good thing for the legal culture. Indeed, I contend that its affirmation of the interpretive process provides a secure point of departure for legal discourse and debate among legal scholars, decision makers, and practitioners. However, while the affirmative message that this perspective brings may be desirable (at least to those who remain committed to the project of liberalism), there is reason yet to be wary. Providing a clearer understanding of the caveat that must accompany the rhetorical (or interpretive) turn in the legal culture is one of the goals this article seeks to achieve.


Should inputs such as bank finance affect innovation in BRICS vs. developed countries similarly? Arguably these elasticities may depend on a country's economic progress (Gerschenkron, 1962; Liu and White, 2001). Applying a combination of DEA and Tobit to a sample of 22 countries, we show how innovation (measured patents, scientific publications and high-tech sectoral output) responds favourably to private-sector R&D. No significant differences are recorded for BRICS countries. Differences emerge between BRICS and non-BRICS for the elasticity of innovative efficiency to banking inputs.


Modeling of a wind diesel integrated system (WDIS) is done to perform under varied wind and load conditions on MATLAB Simulink platform. This hybrid system is design in such a way that uunder low wind conditions, a diesel generator feeds the required power to the load. A load flow controller is designed for WDIS to control the load flow depending on the load condition. The power controller reduces the fuel consumption and running costs of generating hybrid system. The frequency of the system is also monitored. The models of the generation units, the power system and frequency-power control are developed and simulation studies have been performed under various conditions using Matlab/Simulink. It has been demonstrated that this system can provide reliable and good quality power to the customers in WDIS systems.


Accelerated Smart Grid development has introduced a large scale integration of geographically distributed remotely controllable devices as well as complex subsystems such as virtual power plants and microgrids. By analyzing the existing automation systems it has been shown that currently available automation applications do not fulfil all functional prerequisites for controlling complex Smart Grid subsystems. Therefore, there is a need for developing an adequate technical solutions which will enable simplified and accelerated integration of the new subsystems into the power system and automatic adaptation of supervisory-control applications for the new control methodologies. This thesis describes middleware platform which enables streamlined integration of the new subsystems into the Smart Grid by utilizing vertical communication. Semantic description of subsystem functions and communication towards the middleware platform is based on IEC 61850 standard and OPC UA middleware technology. It has been shown that knowing standardized semantic descriptions of the system enables developing applications for automatic integration of the new remotely controllable devices and allows developing optimized control methodologies for the automatized subsystems.


This study evaluated associations between dating partners' risky family backgrounds in childhood and current romantic relationship functioning. One hundred young adult dating couples (N = 200) self-reported childhood risky family environments (e.g., conflict, nonnurturing behavior, neglect) and current relationship satisfaction. Partners also engaged in laboratory-based conflict, which was subsequently coded for positive and negative interaction qualities. Results revealed a positive linkage between males' and females' risky family backgrounds. Actor–Partner Interdependence Modeling, which accommodated dyadic data and controlled for neuroticism levels, indicated that males' riskier family backgrounds were associated with their female partners' greater observed negative interaction qualities (e.g., conflict) and with their partners' lower observed positive interaction (e.g., support, communication skills). Experiencing interparental divorce during childhood moderated the results, with riskier family backgrounds holding more negative implications for subsequent young adult romantic relationships when the parents remained together during childhood compared to when the parents divorced.


This study aims to conduct an extensive detailed analysis of the Odia Braille reading comprehension among students with visual disability. Specifically, the study explores their reading speed and hand or finger movements. The study also aims to investigate any comprehension difficulties and reading errors they may encounter. Six students from the 9th and 10th grades, aged between 14 and 16, participated in the study. We observed participants hand movements to understand how reading errors were connected to hand movement and identify the students reading difficulties. We also evaluated the participants Odia Braille reading skills, including their reading speed (in words per minute), errors, and comprehension. The average speed of Odia Braille reader is 17.64wpm. According to the study, there was a noticeable correlation between reading speed and reading errors. As reading speed decreased, the number of reading errors tended to increase. Moreover, the study established a link between reduced Braille reading errors and improved reading comprehension. In contrast, the study found that better comprehension was associated with increased reading speed. The researchers concluded with some interesting findings about preferred Braille reading patterns. These findings have important theoretical, developmental, and methodological implications for instruction.


The surface temperature of the urban canyons in the city of Sao Paulo is remotely estimated through the use of precision infrared thermometers (IRTs). These instruments are set up on a mobile platform, which moves through the bottom of the canyons. The thermal patterns are verified, along a traverse, through the different kinds of soil coverage and occupation, during the early hours of a typical nocturnal period during the dry season. Air temperature measurements are also taken as well as estimates of the convective Q H flux, between the atmosphere and urban buildings. The presence of an atmospheric urban heat island is well identified around the urban center, with a magnitude of 2°C. Over the vertical surface it appears that this phenomenon is not pronounced, although maximum thermal amplitude of around 6°C between the colder analyzed surfaces and the warmer atmosphere is identified.


Objective To investigate the expression and role of fibroblast growth factor receptor 4(FGFR 4) in renal tissues from the children with renal disease. Methods Paraffin-embedded renal biopsy tissue sections from 28 children with primary nephrotic syndrome(PNS), 18 children with acute glomerulonephritis(AGN), 20 children with Henoch-Schoenlein purpura nephritis(HSPN) and 22 children with isolated hematuria(IHU) were examined by immunohistochemical staining with anti-FGFR 4 monoclonal antibody. Normal renal tissues from 5 nephrectomized patients with nephroma were selected as control. Possible correlation between the expression of FGFR 4 and pathologic lesion score, clinical index of renal disease was analysed. Results The expression of FGFR 4 in proximal tubules, distal tubules and podocytes of children with renal disease are all significantly higher than that of the control group(P0.05). The expression of FGFR 4 in podocytes show negative correlation with pathologic lesion score of glomerulus and proteinuria (P0.05). The expression of FGFR 4 in proximal tubules show positive correlation with pathologic lesion score of tubules and proteinuria (P0.05). The expression of FGFR 4 in distal tubules show negative correlation with pathologic lesion score of tubules and proteinuria (P0.05). Conclusions The over expression of FGFR 4 take part in the onset and development of renal disease, but the role of FGFR 4 is different in different tissues: protective factor to podcytes and distal tubules, harmful factor to proximal tubules.

. In this work, we considered models with periodic radiation cancer treatment which describe the dynamics of cell populations in a tumor. This may also be used to consider dynamics of healthy tissue under periodic radiation exposure. We establish the existence of periodic orbits, by using theory of cooperative systems. We give sufficient conditions for the uniqueness of the periodic solution which then becomes a global attractor. Numerical simulations are performed using specific radiation functions to il-lustrate our analytical findings.


The operation of the sound amplification by stimulated emission of radiation in the nonlinear mode is considered. Liquid with gas bubbles serves as an active medium. Pumping is produced by alternating electric field. The amplification of the useful wave in the plane resonator is investigated analytically.


Background: Albuminuria is thought to be a separate risk factor for stroke. A strong association between diabetes related albuminuria and stroke has been published in the international literature. Albuminuria being a sign of endothelial dysfunction, atherosclerosis is a strong predictor of strokes. Aim: To investigate the albuminuria as a predictor of stroke in diabetics in our population. Study design: Observational study. Place and duration of study: This study was done in the Department of Neurology, Sharif Medical & Dental College/Hospital, Lahore from January to August 2019. Methodology: One hundred and fifty diabetic patients having ages 25 to 75 years presented with stroke were enrolled in this study. Demographics (age, sex, residence and socio-economic status) of the included population and types of stroke were recorded on study proforma after getting brain CT of each patient. Urine for albuminuria was examined under microscope. Results: In this study (63%) were males and 37% were females with M:F ratio 2.54:1. Major portion of the patients (43%) were ages between 25-45 years mean±SD 51.62±8.45. Ischemic stroke was found in 114 (76%) hemorrhagic in 24(16%) and undetermined in 12(8%) patients respectively. Albuminuria was found in 72(48%) patients, Group A 40(69%) had ischemic stroke, 10(17%) had hemorrhagic and 8(14%) had undetermined stroke. Conclusion: It is concluded that is strong relation between microvascular complications with macrovascular complication of diabetes (i.e. albuminuria with stroke). The stoke patients with diabetes has more frequency of albuminuria as compared to non diabetics. Keywords: Albuminuria, T2DM, Stroke, Hemorrhagic.


The author proposes a distinction between subject matter, form (the style of depiction), and content in a painting. The subject matter is what the painting 'is about', but it is not directly perceivable when it has been transformed by the form. The content is the artist's interpretation of subject matter as revealed by the form. Whereas decorative pictures are designed to please, fine art is also designed to inform.  To reveal what is considered the religious a painter is expected to depict the sacred as awesome. In turn, the awe-fullness of what a religion considers sacred should generate the conviction in viewers that their relation to the sacred is of ultimate concern. Furthermore, a painting that belongs to a religious tradition will include in its subject matter a third basic component: institutionalized conventional symbols. These have the function of what the author calls 'conceptual meditation', that is, to visually articulate a religion's understanding of its concern for the sacred. In our time, the response of Christians to conventional symbols of their religion has been declining. These symbols will die, be modified or be replaced. The adequacy of his analysis is tested by the author with reference to a series of paintings.


Abstract Since the onset of the global economic crisis in 2007/2008 two key trends have made it necessary to reconceptualize the relationship between development and sustainability: the rapid rise of the so-called 'BRICS' and the emergence of the green economy discourse and now since 2015 the adoption of the Sustainable Development Goals. To address this challenge with respect to developing economies in the global South, this paper endeavours to fuse the core conceptual concerns of the developmental state and sustainability transition literatures. It is argued that a just transition would consist of a dual commitment to human well-being (with respect to income, education and health) and sustainability (with respect to decarbonization, resource efficiency and ecosystem restoration). However, to understand these processes we need a better understanding of political dynamics, and for this purpose the notion of a socio-political regime is introduced. A case study of South Africa's dual developmental and environmental trajectories is presented, revealing how different it is to the East Asian experience. Although a just transition in South Africa is currently unlikely, the rapid emergence of the renewable energy niche signals what may be possible if political and environmental shocks are experienced by key actors within the socio-political regime.


The Paired box gene 1 (Pax1) transcription factor plays essential roles in the development of axial skeleton, scapula, pelvic girdle, and thymus. Delineating its pleiotropic and molecular roles in the various tissues requires the ability to track and isolate the Pax1‐expressing cells for downstream high‐throughput experiments such as microarray and RNA‐sequencing. With these applications in mind, we have generated two new mouse lines—a Pax1 wildtype (WT) mouse line that co‐expresses enhanced green fluorescent protein (EGFP) with functional Pax1, and a Pax1 knockout mouse line which expresses EGFP under the control of Pax1 promoter, using the internal ribosome entry site (IRES) and 2A‐peptide multi‐cistron concatenating strategies. These mouse lines facilitate the isolation and enrichment of Pax1‐specific cells from Pax1‐positive and Pax1‐null embryos using fluorescence activated cell sorting (FACS). They can be also be used in parallel to investigate the stage‐ and tissue‐specific molecular functions of Pax1. genesis 51:420–429. © 2013 Wiley Periodicals, Inc.

apid increases of end-tidal carbon dioxide (ETco,) concentrations have been identified as ,one of the earliest signs of a malignant hyperthermia (MH) episode (1). This case provides documentation of a progressive clinical episode of MH in which the use of capnographic monitoring may have inadvertently complicated the diagnosis of the syndrome. The case may also represent a modern clinical presentation of MH in the face of current monitoring technology and extremely early supportive care.


Meth o d s : Twenty-eight hips of 26 patients (16 girls, 10 boys; mean age 4.5 years; range 3 to 6 years) were surgically managed for hip instability (subluxation/dislocation) associated with SB. Twenty-four patients (2 bilateral dislocations) had low-level lesions (L4-sacral) and a potential to walk, of which 16 patients presented with unilateral dislocation with functional problems including significant (>2 cm) limb-length discrepancy and scoliosis. Two patients had high-level lesions ( t h o r a c i c L3) associated with unilateral dislocations and were unable to walk. Those with a high-level lesion and some patients (9/26 hips) with a low-level lesion also had hip flexion contractures. Treatment included open reduction, pelvic o s t e o t o m y, proximal femoral osteotomy when necessary, and a spica cast. The patients were clinically and radiographically monitored for a mean of 38 months (range 30 to 48 months).


Objective:To study the diagnostic value of Motor evoked potentials(MEP) and nerve conduction velocity(NCV) in the lesions of motor nerve center,nerve root and peripheral nerve in patients with diabetes mellitus(DM).Methods: MEPs by electrostimulation of cerebral cortex and spinal cord and NCV were performed in 50 patients with DM.Results:The abnormality rate of MEPS was 82%(41/50).The main changes were the prolonged latency and unclear wave form.Central motor conduction time(CMCT) was prolonged in some patients.There was positive correlation between the course of disease and the abnormality rate of MEP.There was no significant relation between the result of MEP and the level of fasting blood sugar.The abnormality rate of NCV was 70%,the main changes were decreased motor conduction velocity(MCV) and sensory conduction velocity(SCV).Conclusions:MEP and NCVmight have an important role in the diagnosis of pyramid tract lesions,nerve root and peripheral nerve lesions,combination of the two methods may provide more complete and objective indexes for function of nevous system in patients with DM.[


Siegesbeckia pubescens is a traditional Chinese medicine widely used for the treatment of inflammatory and autoimmune diseases in clinic. In order to evaluate its therapeutic effect against ulcerative colitis (UC) and elucidate its possible mechanisms, in this study, the effect of aqueous extract of S. pubescens (SPA) on 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced experimental UC in rats was determined. The results showed that oral administration of SPA significantly ameliorated colonic edema, hyperemia, inflammation and anabrosis in TNBS-induced experimental UC in rats. In addition, SPA inhibited MPO and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6 and IFN-γ) production, and up-regulated PPARγ expression in colon. These results indicated that SPA has therapeutic effects against TNBS-induced experimental UC in rats, and its underlying mechanisms involve the modulation of PPARγmediated production of inflammatory mediators. These findings highlight the potential of this traditional Chinese medicine as an agent for use in the treatment of UC.


Geometry of a flat die for polymer sheet extrusion is optimized to obtain a uniform velocity distribution across the exit of the die. While optimizing the exit velocity distribution, the constraint optimization algorithm used in this work enforced a limit on the maximum allowable pressure drop in the die. Effect of the shear as well as elongational viscosity of the polymer on the flow in the flat die is taken into account.

We propose a novel and simple discrete reaction-diffusion model that self-organizes striped and spotted spatial patterns. Through theoretical analyses, we show that the spatial frequency of the generated patterns is proportional to diffusion length. Through extensive numerical simulations, we demonstrate that the model can produce Turing-like striped and spotted spatial patterns.


In recent years, we have faced unprecedented threats by coronavirus (CoV) infections, particularly the ongoing COVID-19 pandemic. To fight back, scientists at the Institute of Microbiology, CAS (IMCAS) together with their collaborators developed a universal vaccine strategy against COVID-19, MERS, and SARS. Animal study showed promising results, and a vaccine candidate against COVID-19 based on this strategy has thereby proceeded to phase II clinical study.

This paper explores the dynamic nature of information technology (IT)‐enabled strategic change by using empirical evidence from a variety of organizational contexts. The pilot research described here uses the MIT 1990s framework (Scott‐Morton, 1991) as the underpinning theory to challenge the dominant approach to the management of strategic change. The preliminary findings provide new insights into how strategic change is pursued and offer a new perspective from which the propositions suggested by Scott‐Morton (1991) and Yetton et al. (1994) can be reformulated. Four change patterns (archetypes) are identified that describe planned or emergent modes of change, driven by different change elements under various circumstances. These findings lead to a redesign of the M/T 1990s framework and suggest new ways of understanding how strategic change can be sustained. Further research is required to explore the link between the archetypes identified and the various methods of change.


A compressed natural gas feeder utilizing a vortex tube to reduce pressure and heat up comprises a compressed natural gas inlet, a high-pressure spherical valve, an automatic isolating valve, a pressure reducing and heating device, a spherical valve and a compressed natural gas outlet which are connected in series through a pipeline; the device is also provided with a pressure sensor, a safety valve and a pressure gauge; and the pressure reducing and heating device consists of a heat exchanger and a vortex tube which are connected in series. The pressure of the compressed natural gas is reduced through the vortex tube, and part of hot gas passes through the pipeline, flows back to the heat exchanger through an adjusting valve, indirectly preheats the pre-depressurization compressed natural gas, is mixed with another part of the depressurized airflow of the vortex tube, and is led to the compressed natural gas outlet. The utility model has the following advantages: the adoption of the skid mounted structure and the integration of the heating, pressure reducing and pressure regulating of the compressed natural gas ensure a compact structure and a small volume; and particularly, external heat source is not needed, the vortex tube can be utilized to output cold and hot gas, and a hot port is adopted, so that stronger adaptability and convenient and flexile use are ensured for users.


With the success of big data and artificial intelligence in many fields, the applications of big data driven models are expected in financial risk management especially credit scoring and rating. Under the premise of data privacy protection, we propose a projected gradient-based method in the vertical federated learning framework for the traditional scorecard, which is based on logistic regression with bounded constraints, namely FL-LRBC. The latter enables multiple agencies to jointly train an optimized scorecard model in a single training session. It leads to the formation of the model with positive coefficients, while the time-consuming parameter-tuning process can be avoided. Moreover, the performance in terms of both AUC and the Kolmogorov-Smirnov (KS) statistics is significantly improved due to data enrichment using FL-LRBC. At present, FL-LRBC has already been applied to credit business in a China nation-wide financial holdings group.
