Abstract In December 2019, a new virus has been discovered, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), leading to coronavirus disease 2019 (COVID-19). COVID-19 has been defined as an evolving disease with different phases. It starts with a mild or asymptomatic phase in which there is minimal disease. Thereafter, most patients recover, however, in 20% of the cases the infection worsens. It is hypothesized that eosinopenia, endothelial injury and the presence of smooth muscle autoantibodies are associated with the severity of the COVID-19. In a subset of 75 blood samples of patients with a SARS-CoV-2 infection at time of hospitalization and 30 healthy control samples concentrations of eosinophils, VEGF, VCAM, endothelin and smooth muscle autoantibodies were determined with hemocytometry, ELISA and immunofluorescence assays. In the group of patients with COVID-19 eosinophils (IQR = 0.0–0.01*109/L) were significantly decreased (p < .001), whereas markers of endothelial damage VCAM (IQR = 740–1120 ng/mL) and endothelin (IQR = 2.0–3.4 pg/mL) were significantly increased (p < .001) compared to the group of healthy controls (eosinophils IQR = 0.09–0.19*109/L, VCAM IQR = 362–561 ng/mL, endothelin IQR = 0.5–1.0 pg/mL). From the multivariate analysis, it is concluded that at time of hospitalization a combination of eosinopenia and increased markers of endothelial damage VCAM and endothelin are characteristic of COVID-19.

The W7-X stellarator has so far performed experiments under both limiter and divertor conditions. The plasma is mostly generated by ECR-heating with powers up to 6.5 MW, and the plasma density is usually limited by the radiation losses from low-Z impurities (such as carbon and oxygen) released mainly from the graphite targets. The present work first summarizes the radiation loss fractions f rad achieved in quasi-stationary hydrogen plasmas in both operational phases, and then shows how impurity radiation behaves differently with the two different boundary conditions as the plasma density increases. The divertor operation is emphasized and some beneficial effects (with respect to impurity radiation) are highlighted: (1) intensive radiation is located at the edge (r/a > 0.8) even at high radiation loss fractions, (2) the plasma remains stable up to f rad approaching unity, (3) the reduction in the stored energy is about 10% for high f rad scenarios. Moreover, effects of wall boronisation on impurity radiation profiles are also presented.


The present work proposes a serie of strategies for evaluation, oriented to highly technical contents courses, where traditional evaluation methods are getting less effective to measure the results in the learning process. At first we consider the actual problematic that exist on these courses, and then we propose how traditional evaluation methods are not so effectives nowadays. At the end, we present some evaluation strategies and the conclusions about them.

In image capture a scene with nonuniform illumination has an influence on the image quality, especially the contrast and detail in dark regions. Generally, the tone curve or histogram of an image is modified to improve the contrast and detail, yet this is in- sufficient as the intensity and chromaticity of the illumination vary with geometric position. Thus, the multi-scaled retinex algorithm has been proposed, where the influence of nonuniform illumination is reduced by partitioning the original image using local average im- ages that are estimated based on Gaussian filtering of the original image. However, the multi-scaled retinex algorithm produces color distortion as the local average images are independently estimated for each channel. In particular, if the chromatic distribution of the original image is not uniform and is dominated by a certain chroma- ticity, the local average image includes not only the intensity and chromaticity of the illumination but also the dominant chromaticity through the Gaussian filtering, thereby distorting the color. Accord- ingly, this article proposes a multi-scaled retinex using a modified local average image to reduce the color distortion by the dominant chromaticity of the original image. As with the multi-scaled retinex algorithm, the local average image is obtained through Gaussian filtering of the original image. The local average image is then di- vided by the average chromaticity value of the original image to reduce the influence of the dominant chromaticity. However, be- cause the average chromaticity value includes the dominant chro- maticity of the original image and the chromaticity of the illumination, the chromaticity removed from the illumination in the local average image needs to be compensated. Therefore, the chromaticity of the illumination is estimated based on the chromaticity of the highlight regions in the original image. The chromaticity of the local average image is then modified by the estimated chromaticity. In experi- ments, the proposed method was found to improve local contrast and reduce the color distortion. © 2009 Society for Imaging Science and Technology.

Abstract Although a decrease in carbohydrate intake and an increase in fat intake among Koreans have been reported, investigations of changes in protein intake have been limited. Thus, this study aimed to explore trends in the dietary intake of total, plant and animal proteins overall and by socio-demographic subgroups in Korea over the past two decades. A total of 78 716 Korean adults aged ≥ 19 years who participated in the seven survey cycles of the Korea National Health and Nutrition Examination Survey 1998–2018 were included. Dietary protein intake, overall and by source, was calculated using a single 24-h dietary recall data. Changes in dietary protein over 20 years were estimated using multiple linear regression analysis after adjusting for potential covariates. For total protein intake, a significant decrease was reported from 1998 to 2016–2018 (P for trendlinearity < 0·001), whereas an increasing trend was observed from 2007–2009 to 2016–2018 (P for trendlinearity < 0·001). In terms of protein intake by source, plant protein intake decreased while animal protein intake increased over the past two decades, indicating steeper trends during the recent decade (P for trendlinearity < 0·001). These trends were more pronounced among younger adults and those with higher household income and education levels. These findings suggest that continuous monitoring of dietary protein intake overall and by source (plant v. animal) across socio-demographic group is needed.


The purpose of this report is to record the results of tests of the compressive strength of duralumin channels, to recommend methods for their design, and to show the application of these methods to the design of channel-trussed beams. Conclusion: Shape effect, as a controlling factor in limiting the ultimate compressive strength of a duralumin channel, is not a question of thickness of material, radius of bend, or extent of flat sheet, but is a function of the ratios of the dimensions of the cross section to the gauge of the material.


One of the major driven forces in the area of applied and computational harmonic analysis over the last decade or longer is the development of redundant systems that have sparse approximations of various classes of functions. Such redundant systems include framelet (tight wavelet frame), ridgelet, curvelet, shearlet and so on. This paper mainly focuses on a special class of such redundant systems: tight wavelet frames, especially, those tight wavelet frames generated via a multiresolution analysis. In particular, we will survey the development of the unitary extension principle and its generalizations. A few examples of tight wavelet frame systems generated by the unitary extension principle are given. The unitary extension principle makes constructions of tight wavelet frame systems straightforward and painless which, in turn, makes a wide usage of the tight wavelet frames possible. Applications of wavelet frame, especially frame based image restorations, are also discussed in details.


As Meredith and Mantel write, "Businesses regularly use project management to accomplish unique outcomes with limited resources under critical time constraints" and more and more frequently, for "internal" (i.e. related to organizational activities and processes) as well as "external" (for instance, building a new airport) tasks. Risk management systems are no exception to this overall dynamic.


One of the main tasks of the NBC Protection Troops is accurate and rapid identification of infectious disease causative agents in case of establishing the fact of biological contamination. Different methods
based on the analysis of nucleic acids are most preferred for this purpose. Most of them are based on DNA amplification by polymerase chain reaction (PCR). The result is detected by electrophoretic separation of amplification products, as well as by registration of endpoint fluorescent signal (FLASH modification) or in real time (PCR-RT). Other methods of DNA amplification, such as ligase chain reaction (LCR) and isothermal amplification, are also applicable in practice. The article also describes some identification methods based on nucleic acid sequencing: multilocus sequence typing (MLST) method, sequencing of individual genes and complete genome sequencing. It is concluded that the
choice of identification method should be based on the goals and objectives, laboratory facilities, availability of trained personnel and funding levels. Despite the fact that the most informative are
methods based on sequencing nucleotide sequences, their implementation in the field is difficult so far due to technological requirements


Flow calorimetric measurements of the excess molar enthalpy HEm of [xC2H5OH–(1–x)N2](g) are reported. The measurements extend over the range 333.9–412.5 K at pressures from 32.7 to 95.1 kPa. These are analysed in terms of an association model involving dimer, trimer and tetramer equilibria. Dispersion and dipolar forces were estimated by using flouroethane as a homomorph for ethanol. Cross-term virial coefficients were small, and could be adequately estimated on this basis. As preliminary calculations showed that the measurements could be fitted by assuming only dimer and tetramer equilibria, this model was adopted. The dimer + tetramer model was found to fit literature values of the isobaric heat capacity and isothermal Joule–Thomson coefficients measured at several temperatures and pressures. Second virial coefficients have been derived from the analysis and a simple equation for B(T) is given.

First-principle density functional theory calculations were performed to explore electronic and structural properties of β-(AlxInyGa1−x−y)2O3 quaternary alloys with both Al-content (x) and In-content (y) ranging from 0% to 18.75%. The β-(AlxInyGa1−x−y)2O3 quaternary alloys exhibit indirect band gap property with the bandgap energy varying from 4.432 to 5.171 eV. Electron effective masses are also presented for β-(AlxInyGa1−x−y)2O3 quaternary alloys, showing a general reduction with In-content increases but a general increment with Al-content increases in the material. Further analysis indicates the possibility of achieving lattice-matched or near-lattice-matched β-(AlxInyGa1−x−y)2O3/β-Ga2O3 structures system, which is critical for high performance field effect transistor and deep ultraviolet photodetector applications. Our work shows that the β-(AlInGa)2O3 alloys with proper tuning of Al- and In-content have strong potential to be used as part of the epitaxial layers for β-Ga2O3-based material system.


The cryptography and steganography can be employed as an appropriate tool for improving the confidentiality of transmissions over the cloud environment. Several of the prevailing steganographic systems are based on the public key steganographic systems such as RSA and ECC where the privacy is based on the complexities in addressing the numerical factorization issues and distinct log-based issues. Moreover, the schemes for addressing the numerical factorization issues and distinct log-based issues enhances statistically. Hence the presence of quantum computing within the extent of 1000 bits can be real-world risks to the system with these issues. The goal is to propose a fresh Quadratic Polynomial Based Post Quantum steganography system that aggregates the post-quantum cryptography with steganography for assuring safety during cloud communication that will be preserved both for traditional computing and post-quantum computing age.


The invention provides an uplink dispatching method for a wireless communication system. The uplink dispatching method comprises the following steps that: an E-UTRAN decides a proposal for allocating a new semi-persistent resource; the E-UTRAN sends the proposal through a physical downlink control channel; a user device receives the proposal in the physical downlink control channel PDCCH and acquires the new semi-persistent resource through analysis; and the E-UTRAN and the user device use the new semi-persistent resource and release the prior semi-persistent resource. The method has the advantages of high wireless resource utilization rate, L1/L2 control channel expense reduction, high reliability, and the like.


A modeling method based on time series autoregressive model (AR) is proposed to address the problem of the existence of random errors in fiber optic gyroscopes, which affects their output accuracy. Based on the time series modeling requirements, the original data is first preprocessed, and then the autoregressive model order is determined according to the AIC criterion, and then the time series autoregressive model is established. On the basis of modeling, the traditional Kalman filtering algorithm and the improved adaptive filtering algorithm proposed in this paper are applied to filter the established signal model, and the filtering results are compared. Finally, the filtered noise coefficients are analyzed by using Allan's variance. The analysis results show that after Kalman filtering, the random error coefficient of the fiber optic gyro has been significantly reduced, which proves the correctness of the random drift model; after the improved adaptive filtering, the random error of the fiber optic gyro has been significantly reduced, which proves the correctness and applicability of the modified filtering method.

This essay reconsiders the chronology of the construction of the cathedral of Bourges, delineating projects prior to the late twelfth-century date proposed by Branner. Two projects emerge, the first going back to the construction of the city wall in the 1170s, and the second from a decade later. In the scheme of rotated triangles the author suggests a critical linkage with Notre-Dame of Paris.


Radhakrishnan posits the Absolute as the ground of the universe. The qualityless Absolute is paradoxically conceived as having an infinite number of possibilities. The ·cosmic process is the actualization of one of these possibilities by God who is the Absolute in relation to this particular possibility. The goal of the cosmic process is the consummation·· of this actualization, or the mastery of the Self over the not-self into which this ·particular possibility differentiated itself as the beginning of the u.niverse. The cosmic process is evolutionary in character. The Self is drawing, as it were, the not-self as an • Unmoved Mover ' through the various stages of life, consciousness and self-consciousness. Man, who is self-conscious, is the latest product of this emergent evolution. ·The whole process .Can be called the evolution of the spirit because not-self or matter represents the lowest depth to which the spirit has descended. It is only a form of the spirit. 3 The existing individual is a microcosm of the macrocosm, a synthesis of Self and not-self, spirit and matter. The not-self which has evolved to the self-conscious level is the empirical self of man. The Inner Self is the Atman which is consub·stantial with the Absolute. The Self is still drawing the notself towards it. But as the not-self is self-conscious in man, it bas to co-operate consciously in the evolution of the spirit. The malady of man is that the empirical self due to avidyii or ignorance loves itself rather th:in the true self. 5 · This malady


Macao was an important base of the Protestant missionaries before the first opium war. Many missionaries' wives who accompanied their husbands and worked as women missionaries contributed themselves to the mission activities in Macao. Sharing the same feature, they engaged in many missions, such as keeping home, helping their husbands, educating native girls and so on, all of which has had great impact on the society in late Qing Dynasty.


The primary purpose or the current study was to explore the academic engagement and social functioning that was exhibited by students with learning disabilities (LD) when instructed in the resource room and in regular education with and without the provision of special services.

This thesis is concerned with the development an analysis for decomposing the binding energy of second-order Moller–Plesset perturbation theory into physically meaningful components. This can be defined as an extension to the previous work on an absolutely localized molecular orbitals based EDA for Hartree–Fock. The decomposition of the correlation energy proceeds though physically motivated constrained intermediate wave functions and corrects the HF description of frozen interaction, polarization, and charge transfer, while adding a description of dispersion that is only possible at the correlated level. This method is implemented efficiently and the performance of the implementation is tested. The EDA is then applied to systems of chemical interest to help resolve questions related to intermolecular interactions.


INTRODUCTION: Stress in medical students is essential for academic achievement. However, persistent high stress over time may compromise performance & personal health. Our study's purpose was to determine the effect of 6-weeks of yoga & meditation on medical students perceived stress & sense of well being prior to exams. METHODS: Between 2013–2015, first through third year medical students at our institution were recruited by e-mail. Participants attended two 1 hour sessions per week of yoga & meditation for 6 weeks. Levels of perceived stress & well being were measured pre- and post-the 6 week intervention, using the Perceived Stress Scale & a Self Assessment Survey respectively. Components of the Self Assessment measured happiness, peace, focus, endurance, positivity, personal satisfaction, self confidence, patience & fatigue. The post intervention surveys were completed the day of the students' written exams. RESULTS: A total of 13 women & 14 men participated. Median age was 28 (24 yrs–32 yrs). 48.1% Caucasian, 7.4% Black, 11.1% Hispanic, 11.1% Asian & 22.2% other. Paired t tests showed a significant reduction in perceived stress (18.44 vs 4.52; P=.004) after 6 weeks. The Wilcoxon signed-rank test showed a significant improvement in feelings of peace, focus, endurance & fatigue. No significant changes in happiness, positivity, personal satisfaction, self confidence or patience were seen. CONCLUSION: Results show 6 weeks of yoga & meditation significantly reduced stress & improved aspects of personal well being in this population. A future larger study including a supported control group may help to validate these results.

The simulation result shows that this control strategy enjoys,compared with which only applied in ac transmission line,a great damping capacity.


One of the difficulties of OPS networks is buffering optical packets in the network. O(1) reading operation is not possible in the optical domain, because there is no equivalent optical RAM available for storing packets. Currently, the only solution that can be used for buffering in the optical domain is using long fiber lines called Fiber Delay Lines (FDL). FDLs provide a small and fixed amount of buffering. Burstiness of Internet traffic and short-term over-utilizations cause high packet drop rates in small and fixed buffered OPS networks. In this paper, we propose an architecture using a XCPbased congestion control algorithm specially designed for OPS WDM networks with pacing at edge nodes for minimizing the buffer requirements at core nodes. We show how the FDL requirements change with the number of flows on a wavelength, FDL granularity and wavelength utilization by using a dumbbell topology. We show the requirements and parameter settings for stable operation and high utilization.

There are several oxygen concentration measurement methods applied in aircraft fuel tank inerting systems. In this work, an aircraft fuel tank inerting experiment system was built and oxygen concentration of the fuel tank ullage (fuel tank space above the surface of the fuel which is filled with fuel vapor and air) and the dissolved oxygen in the fuel was detected with the methods of light absorption and optical fluorescence. The experiment was conducted through different operating conditions and results has illustrated that the light absorption method as well as the optical fluorescence method has the same accuracy sensing calibration gases, but the suitable condition of the two methods are different. Results have shown that the method of light absorption is more suitable to test oxygen concentration of gas mixture, and the method of optical fluorescence is more suitable to detect the concentration of dissolved oxygen in liquid substance.


Here we report identification of a new class of local structural aberrations in lung cancers. The whole-genome sequencing of cell lines using a long read sequencer, PromethION, demonstrated that typical cancerous mutations, such as point mutations, large deletions and gene fusions can be detected also on this platform. Unexpectedly, we revealed unique structural aberrations consisting of complex combinations of local duplications, inversions and micro deletions. We further analyzed and found that these mutations also occur in vivo, even in key cancer-related genes. These mutations may elucidate the molecular etiology of patients for whom causative cancerous events and therapeutic strategies remain elusive.


We consider the prediction of weak effects in a multiple-output regression setup, when covariates are expected to explain a small amount, less than $\approx 1%$, of the variance of the target variables. To facilitate the prediction of the weak effects, we constrain our model structure by introducing a novel Bayesian approach of sharing information between the regression model and the noise model. Further reduction of the effective number of parameters is achieved by introducing an infinite shrinkage prior and group sparsity in the context of the Bayesian reduced rank regression, and using the Bayesian infinite factor model as a flexible low-rank noise model. In our experiments the model incorporating the novelties outperformed alternatives in genomic prediction of rich phenotype data. In particular, the information sharing between the noise and regression models led to significant improvement in prediction accuracy.


A cement composition is provided to inhibit the crack generation by using alpha type calcined gypsum as a cement additive to lower the contraction expansion rate, induce an initial coagulation time and decrease the hydration heat of the cement, improve the resistance against the volume change in accordance with drying and wetting and the freezing and thawing resistance, and improve the tolerance and the crack inhibitory capability by adding a hydrophilic polyvinyl alcohol fiber. A cement composition comprises cement, polymer powder, polyvinyl alcohol cut fiber, silica fume and alpha type calcined gypsum for decreasing the contraction expansion rate. The composition further comprises at least one selected from the group consisting of fly ash, a fluidizing agent and blast furnace slag. A method for repairing and reinforcing using a cement mortar composition comprises the steps of: (a) mixing the cement, alpha type calcined gypsum, silica fume, fly ash, polyvinylalcohol cut fiber, polymer powder, fluidizing agent, and blast furnace slag to prepare the cement composition; (b) mixing the cement composition with heavy sands, fine sands and water to prepare the cement mortar composition; (c) after arranging an object side to be constructed, spraying water thereto to maintain the wet state; and (d) applying the cement mortar composition to the object side.


In this paper, equations of atmospheric and oceanic dynamics are reduced to a kind of evolutionary equation in operator form, based on which a conclusion that the separability of motion stages is relative is made and an issue that the tractional splitting methods established on the physical separability of the fast stage and the slow stage neglect the interaction between the two stages to some extent is shown. Also, three splitting patterns are summed up from the splitting methods in common use so that a comparison between them is carried out. The comparison shows that only the improved splitting pattern (ISP) can be in second order and keep the interaction well. Finally, the applications of some splitting methods on numerical simulations of typhoon tracks made clear that ISP owns the best effect and can save more than 80% CPU time.


Acquired immune deficiencies caused by different etiologies, promote invasive fungal infections. When this immunity begins to improve, it can induce an excessive inflammatory response defined as Immune Reconstitution Inflammatory Syndrome (IRIS). Hepatosplenic Candidiasis (HSC) can be considered a form of IRIS syndrome as it occurs following neutrophil recovery in patients treated for acute leukemia. Differentiating IRIS from a single fungal infection or treatment failure due to a similar clinical picture is a real diagnostic problem. Misdiagnosis and subsequently ineffective treatment with antifungal therapy instead of anti-inflammatory drugs, may lead fatal course of the disease. A deep and prolonged neutropenia developed after the first induction chemotherapy in our two and a half-year-old male patient who was followed up in our clinic with the diagnosis of Acute Myeloblastic Leukemia (AML). Our patient had fever, abdominal pain as well as his Gamma Glutamyl Transferase (GGT) and Alkaline Phosphatase (ALP) levels increased during neutropenia recovery. He was diagnosed with hepatosplenic candidiasis, by observing 'target like abscesses' on dynamic Magnetic Resonance Imaging (MRI) taken for his newly developing symptoms and laboratory findings while recovering neutropenia. After his first and third induction chemotherapy courses, his fever persisted although antifungal therapy, steroid treatment was initiated considering IRIS. After his re-intensification course, because of the same flare-up symptoms, we started immunglobulin in addition to steroid. With methylprednisolone and intravenous immunoglobulin, his symptoms improved and significant regression was observed in the lesions 'target-like abscesses' on MRI and in the laboratory values. Result: IRIS should be considered for patients with hepatic candidiasis whose have persistent fever despite appropriate antifungal therapy. Glucocorticoid should be started first for an anti-inflammatory effect.

High-temperature ablation leads to degradation of the electromagnetic performance of the antenna-radome system during flight, which severely restricts the development of hypersonic vehicles with higher performance and higher speed. Therefore, the non-steady ablation process of the antenna-radome system is analyzed. Based on geometrical optics, the transmission performance of the radome under variations of material and structural parameters that are caused by high-temperature ablation is calculated. In addition, the excitation amplitude and phase errors that are output by the transmitter and receiver (T/R) module and amplified by array power supply ripple are analyzed as the temperature of the antenna is increased. An electromechanically coupled model is established accordingly for evaluating the electromagnetic performance of the antenna-radome system with variations of the material and structural parameters of the radome and the excitation current errors of the array elements. A compensation calculation model of the excitation amplitude and phase of the array elements that is based on the coupled model is presented. Finally, a hypersonic vehicle is considered as an example on which to evaluate the effectiveness of the proposed coupled model and compensation method. Aerodynamic heat analysis is applied to determine the boundary heat flux density of the radome. Transient thermal analysis, in combination with the "life and death element" method, is used to obtain the temperature distribution and ablation morphology of the antenna-radome system in real time. The performance of the antenna-radome system is calculated and compensated at multiple frequencies and multiple scanning angles. The results demonstrate that the coupled model could calculate the electromagnetic performance of the antenna-radome system under high-temperature ablation and that the compensation method can significantly improve guidance performance of hypersonic flight vehicle.


The C*-algebras generated by bilateral and unilateral shifts are studied in terms of certain covariance algebras. This enables one to obtain an answer to the question of when such shifts are G.C.R., or not, or even when they are N.G.C.R.. In addition these shifts are classified to within algebraic equivalence. Introduction. This paper is concerned with certain types of bounded linear operators on separable Hilbert spaces. The types are the weighted shifts, both bilateral and unilateral. These operators have been studied quite extensively and have been found to contain examples of many different types of operator behaviour [4], [15], [17]. Among other results, necessary and sufficient conditions are given here for when such shifts are G.C.R. or type I (?3.4), for when the C*-algebra that they generate contains the compact operators (?2.5, ?3.2), and for when two shifts are algebraically equivalent (?2.4, ?3.3). In order to answer these questions, it is necessary to obtain a useful description of the C*-algebras they generate and of their irreducible representations. For this purpose covariance algebras are most appropriate [3], [9], [10], [23], [24]. In the first part of this paper the results on covariance algebras that are needed are presented. Many of these results are known; they appear chiefly in [24]. In the case of the group Z, some of the proofs are conceptually easier and it seemed worthwhile to present them. The principal new result here is Theorem 1.2.1, in which it is shown that a necessary and sufficient condition on a*homeomorphism S of a compact space X in order that every ideal in the covariance algebra C*(X, S) contain an element of C(X), is that the periodic points be a "small" set. The theorem is in fact proven for a general C*(, Z). The C*-algebras generated by weighted shifts with closed range are completely characterized in ??2.2 and 3.1 in terrns of covariance algebras C*(X, k). Received by the editors July 3, 1974.

O'DONOVAN It is shown that the space X has a certain canonical form which for a given shift makes explicit all of its irreducible representations as weighted shifts. Also this canonical form of X classifies shifts to algebraic equivalence (?2.4, ?3.3). This last term was introduced by W. B. Arveson [21 to describe two operators T and S for which the map T -0 S extends to a *-isomorphism of C*(T) onto C*(S). For normal operators this means they have the same spectrum, so for weighted shifts we have an "induced" version of this result. If the above remarks seem to make little distinction between unilateral and bilateral shifts, this is because as is seen in Parts II and III, the differences are much less than might have been expected. In fact the type of analysis carried out here is almost equally applicable to all classes of centered operators [21]. The terminology and notation used are the standard ones [2], [8]. Thus, for example, L(H) and C(H) denote the bounded linear operators and compact linear operators on a Hilbert space H, C*(d 1) denotes the C* -algebra generated by I I and 1, 21' denotes the commutant of an algebra 2, and H77 denotes the Hilbert space on which a representation 77 of some C*-algebra acts.

Now C*(2T, Z) is defined to be the enveloping C*-algebra [8]. Thus, for F E 11(2, Z) put 1F1II = sup 1|17 (F)l1, 17 where 7T ranges over all irreducible *-representations of l1(2, Z)X One can show [9], [24] that |F|I 0 O F = 0 so C*(U, Z) is defined to be the completion of 11(2, Z) in this norm. More generally, if G is any locally compact group of *-automorphisms of U, then C*(U, G) can be constructed [9], [23], [24]. To every representation p of a covariance algebra C*(OU, Z) corresponds a pair (77, U), where 7T is a representation of 2t, and U is a unitary operator on H7 with the property that UI7(A)U77(x((A)) for all A in 2.

This paper gives a simple method for finding an optimal assignment of operations to work stations when the order of operations is specified. It is shown that the problem with a specific ordering can be formulated as an assignment problem or as a shortest-route problem for which an inspection-type solution is available. The more general problem, when it is possible to enumerate all feasible orderings of operations, can then be handled by repeating the required calculations for all such orderings.


Abstract This article aims at rethinking religious education from an engagement with Derrida's forms of reasoning and analyzing. In the first section Gert Biesta presents deconstruction and shows how we can find deconstruction in education. In the second section Siebren Miedema explores the religious horizon of deconstruction. In the final section the authors outline possible implications for religious education.

Features of a detecting system made for measuring small perturbations in gamma angular correlations are discussed. Four detectors are used, and information from these is collected in several coincidence circuits simultaneously. The operation of the detectors in the vicinity of strong magnetic fields is also of interest. A summary is given of results obtained. (auth)


This paper discusses the air‐borne and structure‐borne insertion losses of acoustic materials attached to sandwich‐composite panels. The main structure is modeled using an analytical model using discrete layer theory. In this model, all layers of the panel are assumed orthotropic, and both symmetric and anti symmetric modes of propagation are accounted for. For both air‐borne and structure‐borne excitations, the transfer matrix method with finite size effect correction is used to account for the effect of the noise control treatment. Moreover, power balance is used to highlight the effect of the acoustic treatments in terms of added damping. A three dimensional finite element modeling based on the mixed (u,p) formulations for poroelastic materials and a sandwich element for the structure is presented and used to validate the model. Several examples including sandwich composite panels and various noise control treatments (foams versus fibers, effect of a resistive screens, etc.) are presented and compared.


N-phenyleimide-arcylonitrile-styrene-butadiene(NPMI-AN-St-BR) tetrapolymer was prepared via continuous bulk polymerization.The effects of NPMI content,polymerization temperature,and feed patterns,etc.on the properties of the products were investigated.Thermal analysis indicated that both Vicat softening point and heat distortion temperatures of the tetrapolymer elevated rapidly with the increasing content of NPMI,whereas the melt flow rate decreased.The comprehensive properties of the tetrapolymer were comparable or superior to two important heat-resistant ABS resins(BH-102H and BH-202).Rheological measurement with torque rheometer showed that the tetrapolymer possessed good processibility.


A wide range of tools can be used for endowing applications with functionality related to user privacy according to customer's requirements and developer's experience. This implies a high investment of resources because it requires team skills in legal areas, computer security, graphic design and cognitive ergonomics. Despite this situation, there are no specific software tools that allow developers to build effective privacy management applications that consider three critical requirements: compliance with legal terms, adherence to budget limitations, and usability for the target audience. This paper proposes applying interaction patterns to reduce current gaps in the interaction between users and privacy notices.


Directional freezing and frozen UV initiated polymerization have been employed to prepare aligned porous stimuli-responsive hydrogels. Oligo-ethylene glycol methacrylates and dimethylamino ethyl methacrylate monomers are used to produce temperature and pH-responsive hydrogels respectively. The aqueous monomer mixtures are directionally frozen in liquid nitrogen and the frozen samples with dry ice are then polymerized by UV irradiation. Aligned porous morphologies are observed in both dry and hydrated states. The hydrogels exhibit stimuli-responsive behaviour in aqueous conditions and anisotropic compressive strength and diffusion behaviour with respect to freezing direction.


Greenhouse gas (GHG) emissions from dairy farms are a major concern. The objectives of this study were twofold: Compare organic, grazing and conventional farms in terms of GHG emissions and economics and assess the impact of mitigation strategies. A survey was conducted on 27 conventional farms, 30 grazing farms and 69 organic farms in Wisconsin. The data collected were used to characterize the 3 different systems scaled to the average dairy farm size (85 cows on 127 ha). The Integrated Farm System Model (IFSM) was used to simulate feeding and manure management mitigations strategies to reduce GHG emissions. Results showed that incorporation of grazing practices for lactating cows on the conventional farm led to a decrease of GHG emissions (-0.16 kg CO2eq/kg of milk (27.6%)) and at the same time an increase in net return to management (+$7,005/year (29.3%)) when milk production was maintained. On the grazing and the organic farms, decreasing the forage to grain ratio in the diet decreased GHG emissions when milk was increased by 5% or 10%. However, the 5% increase in milk production was not sufficient to maintain the net return on these farms. When milk was increased by 10%, net return increased on the organic farm but not on the grazing farm. Changes in manure management including the incorporation of manure into the soil the same day of application and using a 12-month covered storage pit led to a decrease in GHG emissions (-0.08 kg CO2eq/kg of milk (13.7%)) on the conventional farm whereas GHG emissions increased slightly on the grazing (+ 0.04 kg CO2 eq/kg milk (6.1%)) and on the organic farm (+0.06 kg CO2 eq/kg milk (6.9%)). For the 3 farm systems, manure management changes led to a decrease in net return to management. Results showed that the same mitigation strategies led to different outcomes according to farm system. Simulations also demonstrate that there are some feeding and manure management mitigation strategies that are effective for reducing GHG emissions while maintaining or even improving profitability for each dairy farm system studied.


Cover crops are increasingly used for weed management. But selecting the most suitable species of cover crop to be associated with a main crop requires long-term trials. We present a model-based method that uses a reduced number of parameters to help select cover crops in the context of banana cover-cropping systems. We developed the SIMBA-CC model to focus on radiation interception. The model was calibrated for 11 cover crop species by measuring their growth in 4 m2 plots with three levels of shade (0, 50, and 75%). The SIMBA-CC model served to predict the long term growth potential of the 11 cover crop species in function of the radiation under the banana crop canopy. The model was validated using three species in association with banana plants. We defined three indicators based on outputs of the model to assess the ability of each of the 11 species (i) to compete with weeds and (ii) to be maintained in the long-term under the canopy of the main crop, and (iii) to evaluate competition with the main crop for nitrogen resource. This ex ante evaluation revealed the most promising species to be intercropped with banana. Finally, the SIMBA-CC model was used to define the light interception traits of a virtual cover crop that satisfy the three indicators in the case of intercropping with banana. We showed that to satisfy the three criteria, cover crops with low values of optimal photosynthetically active radiation (PARopti) should have moderate maximal biomass productivity, while crops with higher PARopti values should have a higher maximal productivity. The use of functional traits and modeling appears effective to disentangle the relations between intrinsic traits of cover crops and effect traits that affect the performances of the intercropping system.


A depth-sensing and frequency-specific dynamic indentation technique was used to determine the spatial distributions of dynamic moduli, including storage (E') and loss moduli (E), in poly-cis-1,4-butadiene (BR) and brominated poly(isobutylene-co-p-methylstyrene) (BIMS) rubbers with varying degrees of cure and with or without carbon black fillers as a function of penetration depth. The BR rubbers were cured with sulfur and a sulfur accelerator and the BIMS rubbers were cured using zinc oxide and stearic acid. The dynamic modulus reached a constant bulk value after the Berkovich indentor penetrated into rubbers far beyond the surface. Spatially averaged bulk dynamic moduli thus determined using the nano-indentation technique were compared with the tensile extensional moduli and the frequency-dependent dynamic tensile moduli both measured from the bulk rubbers. Spatial distributions of cure and its dependence on penetration depth were evaluated as functions of cure level, filler loading, and sample surface preparation. The ultimate goal is to provide quantitative cure distribution maps in rubber blends and compounds through a combination of Atomic Force Microscopy (AFM) and dynamic nano-indentation characterization.


Porous silicon (PS) as an excellent light diffuser can be used as an antireflection layer without other antireflection coating (ARC) materials. PS layers were obtained by electrochemical etching (ECE) anodization of silicon wafers in hydrofluoric acid/ethanol/de- ionized (DI) water solution (HFlEtOH/H₂O). This technique is based on the selective removal of Si atoms from the sample surface forming a layer of PS with adjustable optical, electrical, and mechanical properties. A PS layer with optimal antireflection characteristics was obtained in charge density (Q) of 5.2 C/㎠. The weighted reflectance is reduced from 33% to 4% in the wavelength between 400 and 1000 nm. The weighted reflectance with optimized PS layers iS,much less than that obtained with a commercial SiNx ARC on a potassium hydroxide (KOH) pre-textured multi-crystalline silicon (mc-Si) surface.


C olitis (inflammation of the colon) can occur as a result of infection with the bacterium Clostridium difficile (also known as C difficile and C diff). The disease results from disruption or removal of normal healthy bacteria from the colon by antibiotics. The C difficile bacterium produces toxins (poisonous substances) that attack the lining of the colon and can cause severe damage to the colon itself. More commonly, C difficile toxins produce diarrhea and abdominal discomfort. Unfortunately, it is resistant to most antibiotics. Complications of C difficile colitis include bowel perforation (a hole in the colon) and pseudomembranous colitis (patches of severe inflammation and pus in the colon). C difficile is one of the most common infections that are typically acquired in health care institutions, along with MRSA (methicillin-resistant Staphylococcus aureus) and VRE (vancomycin-resistant Enterococcus). Hand washing and disinfection, isolation of infected patients, and appropriate antibiotic use are the best ways to reduce spread of these types of infection. The March 4, 2009, issue of JAMA contains an article about Clostridium difficile colitis.

A feeding trial was conducted to investigate the effect of supplementation levels of VE and selenium in diets of does and fawns.Two hundred and forty multiparity does were randomly divided into 4 groups,and each group with sixty does.The fouth group were used as control and fed with basal diets.The rests of the groups were uesd as experimental groups ,the first group fed with VE and Sodium selenite hydrate;the second group fed with VE and powder of Astragalus membranaceus; the third group fed with VE and bruised garlic bulb.The result showed that the conception rate of does in the experimental group were different from those in control group during oestrum(P0.01).The birthrate and survival rate of fawns in the experimental group were also different from the control group(P0.01).The selenium deficiency disease of does and fawns were brought down remarkably by 6.67%and 11.1%.


The present investigation deals with the static analysis of adhesively bonded double lap joint in laminated FRP composites using three-dimensional theory of elasticity based finite element method. Many researchers studied the influences of various parameters on the failure behavior on the composites. In those studies, the typical bonding parameters are surface conditions, ,fillet, bond line thickness ,environmental conditions. The present study deals with the analysis of a double lap joint made of generally and specially orthotropic laminates subjected to longitudinal loads. The out-of-plane normal and shear stresses at the interfaces of the adherend and adhesive are calculated for different adhesive thicknesses .The displacements in laminates and as well as adhesive are also computed. The results of the present analysis reveals that the three-dimensional stress analysis is required for the analysis of double lap joint in laminated FRP composites.


The term bioeconomy has emerged in the last years as an important element for the transition to low carbon economies. However, as a relatively new term, it still encompasses a myriad of meanings, not all of them adequate for the Amazon biome or for biodiversity conservation.This document combines literature review from different areas of social sciences as to forge a concept proposal specific for the Amazonian biome. Here, it is argued that the concept should be process-focused and able to sustain the social-biodiversity of the region, favouring the strengthening of economic trajectories that are linked with the standing forest and flowing rivers, aided by traditional communities' ties with their surroundings. To that effect, by providing a space for development of certain economic practices, amazon cities can play a key role in developing better relationships between society and nature.


Two types of polyimide membranes; one crosslinkable and the other noncrosslinkable using ultraviolet light irradiation (UV irradiation), were prepared and investigated concerning the effect of UV irradiation on their gas permeabilities and selectivities. Permeability and diffusion coefficients for O2, N2, H2, and CO2 were determined using the vacuum pressure and time lag method. Sorption properties for carbon dioxide were carried out to evaluate the changes in the free volume in the membranes due to the irradiation. In both membranes, permeability coefficients for all gases used in this study decreased and permselectivity, particularly for H2 over N2, increased with increasing UV irradiation time without a significant decrease in the flux of H2. The coefficients depended on the membrane thickness, suggesting asymmetrical changes in both membranes due to UV irradiation. It was suggested by an attenuated total reflection (ATR) FTIR method and analysis of the gas sorption properties of the membranes that the physical changes due to UV irradiation at the irradiated side in both membranes significantly affected their gas permeation properties compared with the chemical changes, especially the crosslinking in the crosslinkable type. © 1997 John Wiley & Sons, Inc.

ABSTRACT Studies of government agencies for women identify a series of factors necessary for a high level of commitment to feminist policy. These include strong grassroots pressure, a highly statist political culture, an organizational structure that facilitates cooperation with other government agencies, international norms, and political will on behalf of government leaders (Friedman 2000; Stetson and Mazur 1995). In Chile on the eve of democratic transition in 1989, all of these factors were in place. Since then, however, Chile's government agency for women, the National Women's Service (Servicio Nacional de la Mujer SERNAM), has not proven to be a strong advocate of feminist policies. This study turns to the literature on coalition theory to explain why this is the case. The level of commitment to feminist policy within a women's agency varies depending on whether a government is controlled by a single party or a multiparty coalition. In a single-party government, the agenda of a particular ministry will closely match the platform of the governing party. In a coalition government-whether in a presidential or parliamentary system-the party controlling a particular ministry is in a position to exercise disproportionate control over policy within that jurisdiction, such that the policy may vary from the platform agreed upon by the coalition. In Chile from 1990 to 1999, SERNAM's policies reflected the agenda of the Christian Democrats who served as ministers of the agency. Under their leadership, SERNAM pur sued policies that demobilized the women's movement, limited the movement's impact on policy, and helped to build an alternative base of support among women.


The "breathing"phenomena and turbulence phenomena were found through the gasoline-air explosion experiments in closed shock tube. By the analysis on the pressure time series which were tested by pressure sensors,the pressure digital characteristics in different position of shock tube were obtained. Besides,it was found that the "breathing"phenomenon are connected with the CH concentrations and the carbon dioxide concentration,and there are three kinds of typical pressure curves in gasoline-air explosion experiments,and the turbulence phenomena is connected with the CH concentrations,there is no fixed oscillation cycle and the turbulences are different in different stages of pressure change.

This chapter concentrates on the question concerning what it means when biblical scholars in our days again try to enter the area of computer-assisted textual research. Literary composition and manuscript tradition tend to complicate, or even disturb the study of textual structure and linguistic analysis. The chapter illustrates this complicated relationship of computer-assisted textual analysis and the tasks of philology. It presents three examples of texts taken from the prophets: Isaiah, Jeremiah, and Ezekiel. The goal is also to present some experiments with description and interpretation, especially in the areas where linguistic and literary study meet or even clash. E-philology is not restricted to a special branch of general linguistics; it should be more than the linguistic analysis of a corpus of ancient texts. E-philology is a special branch of cultural studies, because its main interest is in the interaction of design and history. Keywords: biblical scholars; computer-assisted textual analysis; E-philology; Ezekiel; Isaiah; Jeremiah; linguistic analysis; literary composition; textual structure


In this paper, we propose an efficient collaborative recommendation technique for IPTV services. Our technique solves the scalability and sparsity problems which the conventional algorithms suffer from in the IPTV environment characterized by frequent additions and deletions of contents and the large scale in the size of users (homes) and contents. The technique consists of two steps: user group profiling and user-based collaborative recommendation. For user group profiling we propose a scoring method to extract efficient user features from the TV watching history of users. We use CF-IUF, a modified TF-IDF, to represent user-based TV watching patterns by category through analysis of channels and menus of IPTV services. Users are grouped using the ISOData algorithm based on the feature vectors composed of the CF-IUF scores by category. The user-based collaborative recommendation is performed using the profile information of users similar to the target user. We use Pearson's correlation coefficient and Spearman's ranking coefficient to compare and select similar users. We experimented with our method using the data of the actual one-month IPTV services. The experiment results showed the success rate of 93.58% and the precision of 77.40%, which are considered a good performance for IPTV services.


Water extraction(WE),semi-bionic extraction(SBE),water-decoction alcoholprecipitation extraction(WAE) and semi-bionic alcohol-precipitation extraction(SBAE) were respectively used to extract Chinese herbal medicine known as new fertility-promoting intrauterine infusion liquid(NFPL).The content of effective components,epimedium glycoside,berberine,total alkaloid and dry extract,in the extractive liquids were determined to compare the effects of different methods on extraction of NFPL.The results showed that the comprehensive evaluative Y value of four markers in SBE was the largest,up to 26.4160,larger than-2.3243 in WE,-4.0980 in SBAE and-19.9953 in WAE.This indicated that SBE was better than WE and SBAE was superior to WAE.Application of SBAE could increase the content of effective components of NFPL.

The reaction of 2-morpholinoethylamine and cyclobutane-1,1-dicarboxylic acid with potassium tetrachloroplatinate(II) produced the monomeric title complex, [Pt(C6H6O4)(C6H14N2O)]·3H2O. The PtII ion is tetracoordinated and situated in a square-planar environment.


This paper is inspired by the way birds such as albatrosses are able to exploit wind gradients at the surface of the ocean for staying aloft for very long periods while minimizing their energy expenditure. The corresponding behaviour has been partially reproduced here via a set of Takagi–Sugeno–Kang fuzzy rules controlling a simulated glider. First, the rules were hand-designed. Then, they were optimized with an evolutionary algorithm that improved their efficiency at coping with challenging conditions. Finally, the robustness properties of the controller generated were assessed with a view to its applicability to a real platform.


Caching is a widely used technique to boost the performance of search engines. Based on the observation that the speed gap between the random access of flash-based solid state drive and its sequential access is much inapparent than that of magnetic hard disk drive, we introduce a new static list caching algorithm which takes the block-level access latency into consideration. The experimental results show that the proposed policy can reduce the average disk access latency per query by up to 14\% over the state-of-the-art algorithms in the SSD-based infrastructure. Besides, the results also reveal that our new strategy outperforms other existing algorithms even on HDD-based architecture.

The growth rate function rN counts the number of irreducible representations of simple complex Lie groups of dimension N . While no explicit formula is known for this function, previous works have found bounds for RN = ∑N i=1 ri. In this paper we improve on previous bounds and show that RN = O(N).


The temperature dependence of the internal friction and dielectric properties of Bi 12 SiO 20 has been measured in pure and doped with Cr or Al monocrystal that were annealed in vacuum. A number of acoustic loss anomalies were observed and corresponding features in the dielectric characteristics. The results are discussed in the context of the Hutson-White theory and the theory of defect relaxation in an elastic stress field. A model of defect centers is proposed that is consistent with our observations as well as with earlier observed sound attenuation anomalies in crystals of Bi 12 SiO 20


Implantation of implantable cardioverter defibrillator (ICD) is a Class IIb indication in patients with Cardiac Sarcoid and with LVEF 36%-49% despite immunosuppression and optimal heart failure therapy.

 This systematic review and meta-analysis aimed to provide an estimate on the incidence of ventricular arrhythmias and risk of sudden cardiac death (SCD) in patients with CS.

 The terms "Cardiac Sarcoidosis*" AND "Implantable Cardioverter Defibrillator" AND "Sudden Cardiac Death" were searched on PubMed, EMBASE, and Scopus on 21st of September 2018 yielding 759 articles. After exclusions, 12 studies met inclusion criteria.

 The 12 studies consisted of 612 patients with CS of which 534 had ICD implanted for primary or secondary prevention. Assuming appropriate device therapy as a surrogate for SCD, the annual incidence of appropriate ICD therapies and SCD combined was 6.3% (95% CI; 3.5%-9.1%) in primary prevention cohorts, 11.6% (95% CI; 7.8%-15.3%) in secondary prevention cohorts, and 8.7% (95% CI; 6.0%-11.5%) in both cohorts. The mean left ventricular ejection fraction (LVEF) was pooled as 59±7 (n=155) in primary prevention cohorts and 48±15 (n=48) in secondary prevention cohorts. However, the LVEF was 35±13 (n=28) in those with appropriate ICD therapy, and 49±16 (n=47) in those with ICDs without therapy.
 Incidence of SCD in Combined Cohorts

 The incidence of ventricular arrhythmias and SCD is high not only secondary but also in primary prevention cohorts of CS. This data supports the role of implanting ICDs for primary prevention in patients with CS with mild to moderate reduction in LVEF.

The aim of this study was to investigate the effect of garlic constituent diallyl trisulfide (DATS) on the cell‐death signaling pathway in a human breast cell line (MDA‐MB‐231). We observed that DATS (10–100 µM) treatment resulted in dose‐ and time‐dependent cytotoxicity. Treatment of MDA‐MB‐231 cells with a cytotoxicity inducing concentration of DATS (50–80 µM) resulted in an increase in the intracellular level of reactive oxygen species (ROS). Data from assay with MitoSOXTM Red reagent suggest that mitochondria are the main source of ROS generation during DATS treatment. DATS‐induced oxidative stress was detected through glutaredoxin (GRX), a redox‐sensing molecule, and subsequently GRX was dissociated from apoptosis signal‐regulating kinase 1 (ASK1). Dissociation of GRX from ASK1 resulted in the activation of ASK1. ASK1 activated a downstream signal transduction JNK (c‐Jun N‐terminal kinase)‐Bim pathway. SP600125, a JNK inhibitor, inhibited DATS‐induced Bim phosphorylation and protected cells from DATS‐induced cytotoxicity. Our results indicate that the cytotoxicity caused by DATS is mediated by the generation of ROS and subsequent activation of the ASK1‐JNK‐Bim signal transduction pathway in human breast carcinoma MDA‐MB‐231 cells.

The literature on community response to disaster emphasizes the significance of pre-existing bridging social capital in determining successful responses. While the social infrastructure in the form of both bridging and bonding social capital facilitates the kind of community action and social organization that allows for successful community recovery from natural disasters, communities are more likely to take collective action in the long-term recovery process if they have the capacity to act. This capacity to act resides not only in a community's social capital, but also in its cultural capital, which determines how a community engages in collective action. The Community Capitals Framework is used in this research to analyze a rural community's disaster recovery efforts. The analysis indicates that cultural, social, and human capitals were keys to mobilizing the political capital necessary to acquire the financial capital, which in turn was required to restore built and natural infrastructure. Unlike previous research that emphasizes the role of social capital as the primary capital to be mobilized, however, this research adds cultural capital as a precursor to mobilizing social capital. Cultural capital determines how a community engages in collective action.


The Mount Nansen camp hosts approximately 30 mineral occurrences of epithermal and porphyry origin. The largest occurrence is the Brown-McDade with approximately 600 000 tonnes of drill-indicated reserves at 6.1 g/t Au and 55.5 g/t Ag. The majority of the northwest-striking, steeply dipping epithermal quartz/sulphide veins are found within a 12 km long by 3 km wide northwest-trending corridor called the Nansen trend. The precious-metal-bearing veins occur in all lithologies within the Nansen trend and contain (in order of decreasing abundance) pyrite, arsenopyrite, galena, sphalerite, chalcopyrite, stibnite and tetrahedrite. Two types of epithermal veins are recognized: an early "cherty" quartz-sulphide vein with fine-grained pyrite and arsenopyrite; and a later coarse-grained quartz-sulphide vein with pyrite, galena and sphalerite and higher precious metal values. Within the trend is the Mount Nansen porphyry complex which hosts two cores of potassic alteration. The character of mineral occurrences varies with increasing distance away from these Central Porphyry Zone and are here recognized as the Peripheral Porphyry, Transitional and Epithermal zones. Together, they comprise a porphyry-to-epithermal transition. Placer mining is predominant on creeks draining from the porphyry complex, implying a porphyry source for the placer gold.


An ancient (Upper Cretaceous, 77-76.5 Ma, Oldman Formation) river meander deposit, exposed in the Steveville Badlands of Dinosaur Provincial Park, AB., exhibits extensive deformed and chaotically bedded strata. The most impressive features are large scale rotations of inclined heterolithic stratified (sandstone and shale) blocks, up to 6 m high and 50 m long, dipping in the opposite direction to that of the lateral accretion trend (Fig. 2). We observe three separate sets of reversely dipping beds along one badland gully, oriented parallel with the direction of lateral accretion. The large reverse cross-stratified structures rest on shale failure planes, suggesting the structures formed as back-rotational slumps of inclined heterolithic strata that slid down an active point bar slope into the channel before it was buried by subsequent lateral accretion sediments. Chaotic and disturbed sandstone and shale blocks, soft sediment deformation, and evidence for sediment foundering in the upper 3 m of point bar stratigraphy are common throughout the ancient meander bend, atypical of meandering river deposits (Fig. 1). Some of the broken and blocky sandstone strata displays a domino-like effect, with all blocks leaning in the same direction. Overturned sandstone beds resting on interpreted failure planes, attributed to slumping, are suggestive of down-slope failures (Fig. 3). Faulting represents the final form of deformation of stratigraphy with displacements of up to 2 m, and the hangingwall always on the channel side of the meander lobe (Fig. 4). We interpret all of these structures as having been caused by large magnitude earthquakes and tremors associated with Laramide thrusting. The three sets of reversed inclined heterolithic strata encased within normal lateral accretion bedding, are interpreted to record three major seismic events, separated by periods of relative


In this differential RNA-seq study, Wu et al. identified 29 small RNAs expressed by the pig pathogen Streptococcus suis. The authors then went on to show that S. suis strains lacking some of these small RNAs were attenuated in a zebrafish infection model or were more sensitive to killing by pig blood. The study thus provides further evidence that small, regulatory RNAs play roles in bacterial virulence.


ZACA-EEC (Zigbee Ant Colony Algorithm Energy Efficient Cluster) routing protocol is proposed to replace AODV in Zigbee with the aim of increasing reliability for mine equipment monitoring in this paper, which can prolong the lifetime of network remarkably. Taking hydraulic support as an example, the distribution of monitoring nodes can be simplified as chain hierarchy topology, then Free-space model is used to study the topology's optimal cluster of energy, meanwhile, ant colony algorithm is a good method of solving the problem how to select cluster header. Simulation results show that compared with the AODV and LEACH-C, lifetime of ZACA-EEC respectively increase by an average of 65% and 3.5%, and the maximum packet loss rate is 0.87% which is 12% as AODV in the same case, in additional CHSBI (Cluster Header Selection Balance Index) of ZACA-EEC with a mean is 5.6 times that of LEACH-C.

While spectator interest got aircraft off the ground, scientific inquiry initially fueled advances in design. But from a very early date, military application was a driving force. The histories of aircraft, the California Institute of Technology (Caltech), and Jet Propulsion Laboratory (JPL) bring to light the relative roles of science and military in the development of aerospace in Southern California.


Over the last decade, extensive numerical analyses have been conducted on axially loaded uniplanar K gap, T and X joints made of circular hollow sections (CHS), considering a wide range of geometrical parameters and different types of chord load. Based on the large amount of numerical data, in 2007, new joint capacity and chord stress equations were derived for CHS joints. This article presents detailed comparisons made between the (mean) strength equations for K gap joints and the experimental data available. These design equations were first discussed and approved by Sub‐commission XV‐E of the International Institute of Welding (IIW), subsequently published in the CIDECT Design Guide for CHS joints [1] and adopted in the 3rd edition of the IIW Static Design Procedure for Welded Hollow Section Joints [2], which formed the basis for the ISO 14346 recommendations [3] published recently.


The purpose of this study was to investigate the EPIK (English Program In Korea) program and to analyze the effectiveness of the program. The research questions posed in this study were: (1) What is the effectiveness of the EPIK program on primary school children, and what type of instruction do the learners prefer? (2) What effectiveness can be found on the cooperative teaching with native English teachers, and the teacher training program by the native English teacher to the Korean English teachers? (3) How do the native English teachers evaluate the Korean teachers, students, and the teacher training program? Several steps were taken to supplement the literature background with empirical study: (1) The questionnaires were created based on literature review following Lickert standard after testing the validity of the questionnaire items. (2) The tested data were coded, edited, and reedited using a raw data editing program. (3) All data were analyzed by chi-square's test, one-way ANOVA, and Scheffe using SPSS Win PC+. Main findings provided by this study were as follows : (1) The English class should be focused on the meaning rather than form and the Korean teachers should lead the English class in spite of the fluency and accuracy of the native teachers. (2) The Korean teachers who recognize the children's personality well have to charge the English class and a class of immersion program per school should be provided so that the need of parents and children may be accepted. (3) English training courses should be provided for Korean teachers, such as a one year program staying abroad, the English town experience, the immersion program, the exchange student program for teacher's college students majoring in English, the certifying system of communicative competence, and the primary English teacher program for the alternative of EPIK. (4) An English curriculum for cooperative teaching should be established and developed in order to improve the team teaching program of native teachers and Korean teachers. (5) It should be developed that the various English learning programs such as the exchange student programs abroad through sisterhood relationship or cyber learning with the English native teachers and students.

Since the introduction of foreign capital into Macau in 2003,Macau has experienced rapid and tremendous changes in the past decade,it becomes into a world-famous tourist city from a small unknown fishing village.With the rapid social development,Macao SAR Government faces different scales of spatial decision during the decision-making progress and needs very much a powerful,scientific spatial analysis tools to be assisted.Due to the historical reasons,however,the majority of government departments did not have comprehensive geospatial database,failed to integrate geographic data with each other,so there exists many constraints during the process of planning and development.In the past two years,Cartography and Cadastre Bureau integrated the street the doorplate data and construct the Macau street doorplate query system.In this paper,the latest development of Macau geospatial technology and data integration are introduced,and discussed the developing directions of Macau geographic data based on the experience of neighboring area from different aspects in order to solve the problem of data integration and prepare for building geographic data sharing platform in the future.


The flow field of a high‐pressure sphere expanding into atmosphere is solved numerically by the method of characteristics. In addition to the main shock, an inward traveling second shock is found to exist. This shock, together with the initial singularity, is treated successfully by special numerical techniques. Results from numerical calculations indicate a ``late‐stage equivalence,'' i.e., approximately the same shock path and the same peak‐pressure distribution at late times result from two different blasts, provided the initial total energy is the same for both.


In bacterial bone infections, excessively formed oxidants may result in local and systemic oxidative stress. Vitamin C is the major extracellular nonenzymatic antioxidant, also implicated in bone cells metabolism and viability. The physiological functions of vitamin C largely depend on its redox status. We sequentially assessed oxidative stress markers, hydroperoxides and malondialdehyde (MDA), total antioxidant activity (AOA), total vitamin C, ascorbic acid (Asc), and oxidized/reduced vitamin C ratio in 137 patients with acute osteomyelitis (OM). Compared to 52 healthy controls, in OM group baseline serum hydroperoxides, MDA and oxidized/reduced vitamin C ratio were higher whilst Asc and AOA were lower (P < 0.05, resp.). On the other side, total vitamin C levels in patients and controls were similar (P > 0.05), thereby suggesting a relative rather than absolute vitamin C deficiency in OM. During the follow-up, oxidative stress markers, AOA, and oxidizedreduced vitamin C ratio were gradually returned to normal, while there was no apparent change of total vitamin C concentrations. Persistently high values of oxidized/reduced vitamin C ratio and serum MDA were found in subacute OM. In conclusion, acute OM was associated with enhanced systemic oxidative stress and the shift of vitamin C redox status towards oxidized forms.


Background: This study aimed to evaluate the effect of aerobic exercise on fetal outcomes including body weight, fetal length, head circumference, infants' chest circumference, abdominal circumference and Apgar score 1 and 2 in gestational diabetic women. Material and Methods: Thirty gestational diabetic women were randomly distributed into two groups equal in number. The control group received insulin therapy and diet recommendations, while the exercise group received the same treatment and aerobic exercise in form of treadmill training for 30 minutes/day for 3 times/week. Results: Comparing both groups post-intervention, results revealed that there were statistically non-significant differences in the gestational age (p=0.48), infants' length (p=0.86), head circumference (p=0. 15), infants' chest circumference (p=0.09), and Apgar score 1 (p=0.051). However, there was a statistical significant decrease in infants' weight (p=0.003), and abdominal circumference (p=0.001), as well as a statistical significant increase in Apgar score 2 (p=0.02). Conclusion: The aerobic exercise showed improvements in the fetal outcomes without producing any harmful effects to infants of diabetic women.

The basic study of the electrification occurring during the melting or the freezing of slags reported in the 1st report has carried out for KCI. KC1 is prepared in a silica tube which is fixed horizontally in a preheating nichrome coil, by which the temperature of KC1 is maintained over 620•Ž. Following the movement of a movable electric furnace outside of the coil, the melting or the freezing of KC1 in the silica tube can be occurred along the axis of the tube. During the phase changes of KC1, the solid has generally a positive charge with regard to the melt. The magnitude of the e. m. f., ca 0.33•}0.03V, is independent of the freezing-or melting-rate over a wide range. The shape and distance of Pt electrodes have little effect. Another measurement of the e. m. f. between the solid and the melt at a stationary state with a constant gradient of temperature shows the e. m. f. is negligiblly small. It is, therefore, concluded that this electric phenomena appears while the phase changes are occurring.


Laskowice is a village located in Kujawsko-Pomorskie Voivodeship, in Świecie Upland near Świecie. On the edges of the village there is a manor-palace complex established by Franz von Gordon in the first half of the 19th century. Since the palace was destroyed in 1945, the maintenance of the park was ceased. Currently the object is administrated by Dąbrowa Forest District. The aim of the study was to determine the direction of vegetation transformation of the park in the light of lack of use. Lack of human interference within examined object has initiated regeneration processes. At present the vegetation of the park refers to structure and species composition of natural forest plant communities. Phytosociological research carried out in 2015 and 2016 revealed the presence of following associations: Ficario-Ulmetum , Fraxino-Alnetum and Tilio-Carpinetum. Shrub vegetation of Rhamno-Prunetea class develops in places. Non-forest vegetation of meadows ( Arrhenatheretum elatioris ) and nitrophilous edges ( Urtico-Aegopodietum ) are present. In case of analyzed object the physionomy and species composition of forest communities differs from typical forms. An attention is paid to a strongly developed layer of brushwood. There is a lack of some characteristic species, alien species are present in treestand and shrub layers. A large share in phytocoenoses of Ficario-Ulmetum and Tilio-Carpinetum has Sambucus nigra and in case of the first association also alien species – Philadelphus coronarius and Symphoricarpos albus . Values of calculated indices of synanthropization confirm the regeneration of forest communities: index of natural character achieves value 40% and synanthropization index ranges from 48.78% for Tilio-Carpinetum to 60.00% for Fraxino-Alnetum.

Saphenous vein (SV) graft disease represents an unresolved problem in coronary artery bypass grafting (CABG). After CABG, a progressive remodelling of the SV wall occurs, possibly leading to occlusion of the lumen, a process termed 'intima hyperplasia' (IH). The investigation of cellular and molecular aspects of IH progression is a primary end‐point toward the generation of occlusion‐free vessels that may be used as 'life‐long' grafts. While animal transplantation models have clarified some of the remodelling factors, the pathology of human SV is far from being understood. This is also due to the lack of devices able to reproduce the altered mechanical load encountered by the SV after CABG. This article describes the design of a novel ex vivo vein culture system (EVCS) capable of replicating the altered pressure pattern experienced by SV after CABG, and reports the results of a preliminary biomechanical conditioning experimental campaign on SV segments. The EVCS applied a CAGB‐like pressure (80–120 mmHg) or a venous‐like perfusion (3 ml/min, 5 mmHg) conditioning to the SVs, keeping the segments viable in a sterile environment during 7 day culture experiments. After CABG‐like pressure conditioning, SVs exhibited a decay of the wall thickness, an enlargement of the luminal perimeter, a rearrangement of the muscle fibres and partial denudation of the endothelium. Considering these preliminary results, the EVCS is a suitable system to study the mechanical attributes of SV graft disease, and its use, combined with a well‐designed biological protocol, may be of help in elucidating the cellular and molecular mechanisms involved in SV graft disease.

The purpose of this study is to achieve machining of a split equal-base circle bevel gear. Based on the equal-base circle bevel gear theory, a cutting coordinate system for the separate piece is developed, and the tooth surface processing path of the separate piece is analysed and planned. According to the working principle of the equal-base circle bevel gear, by analysing the cutter position and posture, the calculation method for the angle between the wheel blank coordinate system and the fixed space coordinate system is derived when machining the separate piece for different spiral angles as well as various concavity and convexity properties. The explicit function expressions for the cutter centre coordinates and axis vectors for machining the separate piece are obtained. Using MATLAB, the tool position model is verified by means of calculation, and the tooth cutting simulation of the separate piece is carried out using VERICUT software. By machining experiment and tooth surface measurement analysis, the feasibility of machining the separate piece and the correctness of the tool position mathematical model are verified.
