Understanding the current response at an electrode from suspended solid particles in an electrolyte is crucial for developing materials to be used in semi-solid electrodes for energy storage applications. Here, an analytical model is proposed to predict and understand the current response from non-disintegrable solid particles at a rotating disk electrode. The current is shown to be limited by a combination of ion diffusion within the solid particle and the mean residence time of the particle at the rotating disk electrode. This results in a relationship between current and angular frequency of I∝ω^(3/4), instead of the classical I∝ω^(1/2) predicted by Levich theory. Specifically, the current response of Li4Ti5O12 (LTO) microparticles suspended in a non-aqueous electrolyte of lithium hexafluorophosphate (LiPF6) in ethylene carbonate: diethyl carbonate (EC:DEC) was determined experimentally and compared favorably with predictions from the proposed analytical model using fitting parameters consistent with the experimental conditions.


As a research task, the authors define the features of the use of the resource reservation protocol (RSVP) in modern networks of MPLS (Multi protocol label switching) technology, which provides an increase in the throughput of delay-sensitive voice and video traffic. The RSVP protocol allows you to transfer requirements for the level of Quality of Service (QoS) with reference to data flows. The article discusses the characteristics of the RSVP protocol. The use of RSVP of three reservation styles is considered, as well as an extension of RSVP that supports better QoS, the establishment of explicit routable paths (LSP) with or without reservation, the possibility of LSP redirection. The benefits of segment routing (SR) are discussed in giving the network operator more control over the network, simplifying the network, and supporting class of service. It also discusses the protection mechanisms for MPLS-TE tunnels to provide failover.


The polyhedron model provides one possible approach to model-based program analysis and transformation. Over the years, it has undergone many improvements in order to handle a still growing class of programs. A recent approach enabled the use of non-linear parameters, which was in that generality not possible before. While this new framework uses real quantifier elimination, the present work examines possibilities to describe the integral solutions to certain problems occurring in the polyhedron model exactly. In particular, we study the solvability of systems of linear Diophantine equations in one and several non-linear integral parameters and demonstrate the applicability of the developed methods for Banerjee's data dependence analysis.


This paper analysis the active power filter and instantaneous reactive power theory.In order to let the active power filter could be used in 3-phase 4 wires circuits,a new method of harmonics detection is given in this paper,which is based on p-q method and ip-iq method of the instantaneous reactive power theory.This method remove the zero current,so it could be used in 3-phase 4 wires circuits and the result is accurate even if the voltage is distortion.The result of the simulation shows that the method is correct.The problem which the active power filter could not be used in 3-phase 4 wires circuits is solved by this effective method.


We propose a method for recognising polyhedral objects from either their weak perspective or orthogonal projection on an image plane. The method is applicable for one solely polyhedral object per image. Each solid object is represented by an attributed graph whose nodes represent the object faces and the arcs represent the edges formed by the intersection of adjoining faces. Each node of the graph is associated with an attributed vector consisting of a set of wavelet transform based affine invariant features in addition to a scalar feature. This scalar feature is the type of shape which the face belongs to. Each arc is attached with one scalar attribute value which is the angle between two adjoining faces corresponding to the ends of that arc. A hierarchical matching algorithm is proposed for recognising unknown objects based on the attributed graphs. The algorithm consists of four stages arranged in the order of increasing computational complexity. The proposed method has been tested with several polyhedral objects in synthetic as well as real images. Experimental results show that in most cases, a single projection image is sufficient to recognise the unknown object in the scene.


In most practical problems where traditional numeric simulation is not adequate, one need to reason about a system with both qualitative and quantitative equations. In this paper, we address the problem of propagating qualitative values represented as interval values through quantitative equations. Previous research has produced exponential-time algorithms for approximate solution of the problem. These may not meet the stringent requirements of many real time applications. This paper advances the state of art by producing a linear-time algorithm that can propagate a qualitative value through a class of complex quantitative equations exactly and through arbitrary algebraic expressions approximately. The algorithm was found applicable to Space Shuttle Reaction Control System model.


A general characteristics of the infection is presented, the infection agent features, as well as the epizootology, clinical manifestations, diagnostics & specific prophylaxis of orf in sheep and goats, and control measures against the infection are described.


This paper describes the early vision of bio-inspired neuromorphic system, modelling the primitive behaviour of visual cortex to implement the robust performance of detecting vehicle passengers for the new emergency system for vehicle accident (ePOST). The proposed neuromorphic vision mimics the cat's visual cortex experimentation of Hubel and Wiesel. The directional visual signal selectivity of cortex is introduced to implement the neuromorphic vision and the CMOS spiking neuron based on Hodgkin-Huxley formalism. The feasibility of neuromorphic early vision is demonstrated for applications of the transportation safety system of passengers' occupancy detection based on the recognition of human head figures.


Recently, the main treatment for esophageal cancer remains curative resection combined with adjuvant chemoradiotherapy. With the application of minimally invasive esophagectomy (MIE) in the surgical treatment in recent years, patients with esophageal cancer who received MIE are proved to have less postoperative complications, better quality of life, and better surgical effect. However, different operation methods of MIE have different advantages and disadvantages, that makes the clinical promotion of MIE need further clinical experience, surgical techniques and procedures. The long-term effect of MIE remains to be further verification.

The efficiency of a long-span structure relies on how material is locally distributed within a fixed structural shape. In this paper a design procedure for thin plates made of three layers of a depleted material subject to a distributed vertical load is proposed. The investigation is driven by the idea of the optimal material organization and has the objective of maximizing the overall stiffness/weight ratio of the structure. Two microstructural architectures of the media are considered: a porous solid structure and a truss arrangement. For each type of microstructure the flexural stiffness has been correlated to the level of depletion by the use of a power law function by setting very few parameters. Finally, invoking the principles of structural homogenization theory, the global flexural response of the plate has also been calculated. The validity of the method is demonstrated by comparing the analytical results with those obtained by a numerical finite element simulation of the structure based on a detailed model of the media.


We consider the multi-sensor tracking systems. In order to solve the sensor registration in multi-sensor tracking system, we propose a new solution based on improved Bayesian regularization algorithm using neural networks in this paper. The nonparametric nature of this approach guarantees that many different kinds of sensor biases can be registered adequately; Levenberg-Marquardt optimum algorithm integrated with Bayesian regularization is applied to solve the registration problem with quick convergence rate and high resolution. Simulation results show the advantage of convergence and generalization as compared to the parametric algorithms and LM optimum algorithm.


Recently, permanent magnet assisted (PMa)-synchronous reluctance motors (SynRM) have been introduced as a possible tractions motors in hybrid electric vehicle applications. In order to achieve maximum torque per ampere (MTPA), knowledge of the motor parameters is necessary. Due to the high ambient temperature inside the engine cavity and also saturation effect, variation of the motor parameters such as inductances and permanent magnets flux density is not avoidable. Off-line models for estimating the motor parameters are known as a computationally intensive method, especially when the effect of cross saturation and permanent magnet flux deterioration are included. In this paper, a practical maximum torque per ampere control scheme along with a simple parameter estimator for PMa-SynRM is introduced. This method is capable of maintaining the MTPA condition and stays robust against the motor parameters variations. To verify the validity and feasibility of the proposed controller, several simulations and experiments results on a low power laboratory prototype PMa-SynRM have been presented.

The policies for thwarting attacks on systems vary greatly in complexity, ranging from simple static firewall rules to complex stateful protocol state machine analysis. As intrusion detection systems are getting integrated into firewall solutions, there is a need for a language that can define both firewall policies and system intrusion behavior and exhibit inter-operable traits. This paper presents an XML based, self-documenting State-Aware Firewall Language (SAFire) that is designed to express the various kind of firewall and intrusion behavior.


Intelligence officials are addressing the lack of scientific expertise within the U.S. intelligence community by opening up their biological research program--most of which is classified--to external peer review.


An account is given of beach trials in which a number of dispersant concentrates were assessed for their effectiveness in dispersing water-in-oil emulsions prepared from a medium viscosity fuel oil, and crude oils from Saudi Arabia (Safaniya) and the North Sea (Claymore). Subjective comparisons were made using a hydrocarbon-base dispersant as reference. Some of the dispersant concentrates performed exceptionally well, offering a more-efficient, and in some cases, cheaper alternative to the hydrocarbon-base dispersant commonly used at present for cleaning up oiled beaches.


In this paper, by using pairwise fuzzy semi Gδ-sets and pairwise fuzzy semi dense sets, the concept of pairwise fuzzy semi weakly Volterra space is introduced and studied. Example is given for pairwise fuzzy semi weakly Volterra spaces. Several characterizations of pairwise fuzzy semi weakly Volterra spaces are also given in this paper. The inter-relations between pairwise fuzzy semi Volterra and pairwise fuzzy semi weakly Volterra spaces, are also established.


TAKE A LOOK AT THE STANDARD TEXTBOOKS on post-World War II America. You will search in vain through the index for references to the Internet or its predecessor, the ARPANET; even mentions of "computers" are few and far between. The gap is hardly a unique fault of these authors; after all, before 1988, the New York Times mentioned the Internet only once-in a brief aside. Still, it is a fair guess that the textbooks of the next century will devote considerable attention to the Internet and the larger changes in information and communications technology that have emerged so dramatically in recent years. Few will share Wired publisher Louis Rossetto's hyperbolic claim that the digital revolution presages "social thanges so profound their only parallel is probably the discovery of fire."1 But most historians will feel compelled to reckon with the emergence of the Internet as a standard feature of everyday life. How will that history be written? Four recent works offer some clues by addressing the history of the Internet from different perspectives (biographic,


The Vitas patrum Emeritensium, the Lives of the Fathers of Mérida, written in the seventh century, sets out the deeds of the holy men of one of the major cities of Visigothic Spain.1 Its account of Bishop Fidelis, who lived in the midsixth century, tells of a servant, or puer, of the bishop who was locked out of the city one night and had to wait till dawn to get in. As he waited, he saw a fiery globe, glovus igneus, going from the extramural church of S. Fausto to that of S. Lucrecia, and a multitudo sanctorum following it, with Fidelis in the middle; they crossed the great Guadiana bridge, and the gate opened by divine power to let them into the city, closing again afterward. The servant told the bishop about this when he came into town the following day, and Fidelis warned him to tell no one during the bishop's lifetime, for fear for his life. These were wise words. Another man saw Fidelis process with the saints from the church of S. Eulalia, Mérida's main civic saint, around the other martyrial churches outside the walls (these would presumably have included Fausto and Lucrecia again) but did tell people; the bishop warned him that he would die at once, and he did.2 On one level, it is quite clear what Fidelis was supposed to have been doing, apparently routinely: he was protecting Mérida in secret, with the most powerful set of associated protectors he could possibly work with. Processing around the walls of a city was a standard way of doing this, as we shall see; not many processions had as much massed saintly backup as these, however.3 At least one of the processions also ended with a formal entry into the city, the classic way of expressing power over it; we can guess that the saints ended up in the cathedral afterward, as processions generally did, for when Fidelis was due to die, it was there that they gathered to ensure his death and to take his soul away. The unusual feature of these stories was

PURPOSE: A method for providing unlawful ME(Mobile Equipment) user information is provided to prohibit the use of an unlawful ME by adding IMSI(International Mobile Station Identity) and MSISDN(Mobile Subscriber Integrated Service Digital Network) information of a mobile subscriber in an MAP(Mobile Application Part) protocol message. CONSTITUTION: An MAP protocol message including IMEI(International Mobile station Equipment Identity) information, IMSI information and MSISDN information is received from an MSC(Mobile Switching Center)(S10). A database is retrieved by using IMEI information, and a service grade of a UE is confirmed(S20). If the UE is an unlawful UE(S40), IMSI information and MSISDN information are stored in a corresponding record of the database(S50). Information included in the received MAP protocol message is recorded in an unlawful UE use information storing file(S60). An alarm signal is transmitted to an operator interface block(S70).


Likely progenitors for gamma-ray bursts (GRBs) are the mergers of compact objects or the explosions of massive stars. These two cases have distinctive environments for the GRB afterglow: the compact object explosions occur in the interstellar medium (ISM) and those of massive stars occur in the preburst stellar wind. We calculate the expected afterglow for a burst in a Wolf-Rayet star wind and compare the results with those for constant, interstellar density. The optical afterglow for the wind case is generally expected to decline more steeply than in the constant density case, but this effect may be masked by variations in electron spectral index, and the two cases have the same evolution in the cooling regime. Observations of the concurrent radio and optical/X-ray evolution are especially useful for distinguishing between the two cases. The different rates of decline of the optical and X-ray afterglows of GRB 990123 suggest constant density interaction for this case. We have previously found strong evidence for wind interaction in SN 1998bw/GRB 980425 and here present a wind model for GRB 980519. We thus suggest that there are both wind-type GRB afterglows with massive star progenitors and ISM-type afterglows with compact binary star progenitors. The wind-type bursts are likely to be accompanied by a supernova, but not the ISM type.


This hands-on workshop introduces a foundation for designing tangibles for children. Participants engage in a low-fidelity design challenge using the iPad Osmo system. We focus on how designing tangibles for children is unique from other design problems and processes. We walk participants through an outcome driven design process using the award winning Developmentally Situated Design (DSD) card set -- focusing on cognitive, emotional, physical, and social skills specific to children at different ages. Small groups create solutions for the same design challenge, but focus on the skills and abilities of a specific age group. We facilitate a compare and contrast exercise of their solutions to help synthesize the complexities of, and showcase skills for, designing child-centric tangibles. Participants are encouraged to review the DSD II cards in advance, available at www.antle.iat.sfu.ca/DSD, as well the papers [1, 2, 3], to get the most out of their workshop experience. These artifacts and papers will be used to within the workshop for hands-on learning and conceptual discussions.


It is not surprising the US is trying to recruit nurses from here (news December 15) - Americans are aware that most UK nurses are underpaid, overworked and undervalued by our own system.


N-type indium doped CdTe grown on n+-GaAs by molecular beam epi- taxy has been studied by the standard deep level transient spectroscopy and the isothermal Laplace-transform deep level transient spectroscopy. It was found that the Cd/Te flux ratio strongly influences the deep level transient spectroscopy results. The unusual temperature dependence of the electron emission rate in films grown at nearly stoichiketric conditions may point out that the observed defect is resonant with the conduction band. PACS numbers: 68.55.Ln, 73.61.Ga Any intentional doping of semiconduction may lead to a formation of un- desired deep electronic states associated with point defects. The presence of deep states influences properties of the doped material and affects the performance of devices fabricated from it. Thus, an issue of primary importance is to develop such growth techniques which can eliminate deep states, or at least, which result in reducing their number in the material. In two recent publications we have reported on the molecular beam epitaxy


Abstract:This article examines both the origins of the "free state" concept in U.S. history as well the little-known, brief period that Delaware was widely considered a "free state." Americans had long talked about "slaveholding" and "non-slaveholding" states—but it was not until the late 1810s and early 1820s that northerners began to use the words "free state." This change represented a rhetorical escalation from "non-slaveholding state" to a term with an even clearer moral valence. But it was not originally obvious to observers exactly which states should be included in the "free" cohort, and, for a time, white Delawareans were successful in convincing themselves and their fellow Americans that they should be counted amongst the northern free states. This article charts Delawareans' arguments in favor of their "free state" status, as well as, over time, their state's fall from grace into the "slave state" category. That it was only in the years after the Missouri Compromise that a nebulous group of non-slave states solidified into an identifiable core of "free" ones demonstrates that the development of the sectional divide in the pre-Civil War era was more gradual and more uncertain than previously thought. It reveals a process of negotiating a "free" identity on a state level that did not mirror reality on the ground. Finally, it uncovers the rhetorical process behind the large-scale erasure of enslaved African Americans' realities in the creation of the "Free North" myth along its borders, even when the evidence of their existence and their experiences would have been impossible for their white neighbors to ignore


Louis Émile Javal was a pioneer in the early history of orthoptics (Figure 1). To anyone knowledgeable about binocular vision, the name Javal conjures up discussions of physiological diplopia, stereoscopes, and fusion training exercises. Javal was a prolific designer of optical devices to use in orthoptic training and ushered in a new era of binocular instrumentation.1–4 Although Wheatstone is accredited with designing the first stereoscope, Javal was an admirer of the instrument and later designed his own version.1,3 He has often been called the Father of Orthoptics.1, 4, 5 He was influenced by his family's history of strabismus. The Javal grid is an instrument of historic interest to most orthoptists, and the principle on which it is based is still in common use (Figure 2). He wrote his Manual of Strabismus in 1896.6 Javal was also well known in general ophthalmology circles for his interest in intraocular pressure and keratometry. He developed several instruments such as the Javal-Schiøtz ophthalmometer. His refraction technique combined the use of a retinoscope with a keratometer. Javal had a particular interest in astigmatism, perhaps in part because of his own refractive error.7, 8 In an ironic twist of fate, he lost his vision in later life from glaucoma and became an advocate for blind people, even writing a book discussing practical adaptation to blindness. He was also an enthusiastic disciple of Esperanto and encouraged blind


An original version of this paper was pre-circulated for the 1978 Conference on Hunters
and Gatherers held in Paris, June 27-30 as, "The Future of Hunters Within Nation States; and the Theory and Practice of Anthropologists." One thread of discussions at this conference was led by anthropologists working closely with several Indigenous peoples in Canada, Australia and the United States who were facing large scale resource developments or making substantial claims for recognition of their land rights and governance. This led to the inclusion of an additional session at the conference on the implications of these developments. The paper presented here is an expanded post-conference version. The conference discussions also profoundly shaped the major theme of the published volume that was developed from the conference. A version of this paper appeared in that volume as: "The Future of Hunters Within Nation States: Anthropology and the James Bay Cree," in Politics and History in Band Societies, Eleanor Leacock and Richard Lee, eds. Cambridge: Cambridge University Press, Pp. 373-417. A copy of my pre-conference paper is included with this MacSphere entry.


The aim of this study is to build a classifier model based on spectra data collected using handheld spectrometer that can classify between different types of food powders (flour and starch). A total of 70 samples were prepared from three different types of flour (whole wheat, organic wheat, and rice flour) and two different types of starch (corn and tapioca starch). Handpalm size handheld spectrometer is used to record the spectrum of each sample, the spectrometer has wavelength range of 900nm to 1700nm. The spectra data is pre-processed using gaussian smoothing to filter the data from noise and unrelated information. Multivariable data analysis method as principle component analysis (PCA) is used to eliminate irrelevant data and reduce the number of variables to three principle components for easier analysis and visualization. Support vector machine (SVM) is used to build a classification model. The training/calibration of the model was done by using 80% of the dataset while the remaining 20% was for testing the model. The results show that with proper pre-processing and PCA, classification of 100% accuracy can be achieved. This study indicates the potential future application of this approach for rapid detection in food powders fraud and adulteration.


Cloud computing is a very popular topic in the IT fi eld in recent years, OpenStack is likely to become the future standard on the cloud computing platform, and it has received extensive attention of the global IT industry. This paper introduces the logical architecture and Service architecture of OpenStack cloud computing platform, and mainly introduces three main function modules, OpenStack Compute, OpenStack Object Storage and OpenStack Image Service, and the relationship between them, and other related information.


The density of states of Pd in Cu given by impurity calculations is shown to be incompatible with the observed profile of Pd Auger transitions. Extended x-ray-absorption fine-structure experiments show that there is a local expansion of the lattice around Pd impurities in Cu but not in Ag. An analysis of the influence of the local lattice expansion on the electronic structure of CuPd alloys shows that it leads to a reduction in the intensity of the Pd density of states at the bottom of the band and yields a Pd density of states in good agreement with the observed Auger profile.


Chinese Youth: A New Generation for New Challenges? Karl Mannheim's theory considers that the changes in the context of socialization of the new cohorts and the change of lifestyle are the key components of the formation of the "socio-historical generation". Going along with this statement, this paper regards the most important challenges that Chinese youth is facing as the matrix of the formation of a new generation which emerged when the Great Opening and the Four Reforms decided by Deng Xiaoping became effective for a large part of population. It took 15 years to implement and put into motion this radical change in economy, society and culture. And it is only in 1995 – 2000 that the making of a new generation became concrete. Four key challenges can be identified that characterize this new generation by its difference: an aging society and a deficit of young women, a system of formation that goes faster than the economy and the labor market, youth unemployment and the compulsory modernization of the whole system of production and the transformation of sexual behaviors, family life that indicate a deep and steady transformation of norms and values in private life.


This special issue contains invited papers from the 5th International Conference on Textile Biotechnology, which was held in October 21 24, 2007, in Wuxi, China. The conference was attended for more than 100 scientists from 16 countries. All presented contributions dealt with research on biocatalysts for textile applications, aiming at greener processes, and they represent recent research in the area. Two major reviews discuss the state of the art in the use of enzymes for textiles (Araújo et al.) and for modification of synthetic fibres (Silva et al.) in particular. Araújo et al. provides the view of the enzymologist, while Silva et al. covers bio-applications in manmade fibres. Biotransformations of synthetic fibres continues to be a hot topic in this research field with reports on the modification of polyethylene terephthalate (Feuerhack et al. and Almansa et al.) and polyamide (Almansa et al.). Site direct mutagenesis of endoglucanases (Qin et al.) and general cellulase applications in textiles (Rau et al.) demonstrate continued interest of researchers in improving the most successful enzymes introduced into the textile industry in the last 20 years. The treatment of wool, targeting anti-shrinking properties is always a priority and different approaches with modified proteases (Smith et al.), and transglutaminases (Cui et al. and Hossain et al.) are covered. Biopretreatment is one of the areas of textile processing where there is a need for new catalysts, because existing treatments are done at alkaline pHs, and large amounts of washing water is used for neutralization. New approaches for biopretreatment are reported by Agrawal et al., using cutinase and pectinase for bioscouring. Czisar et al. report new approaches in solid fermentation to produce redox and hydrolytic enzymes for biopretreatment. Also, the best conditions for biodegradation of polyvinyl alcohol, commonly used as a sizing agent, are described (Zhang et al.) An innovative process is suggested by the immobilization of catalases in cotton fabrics for removal of the hydrogen peroxide after bleaching (Fan et al.). Finally, an interesting report on the bioconversion of oleic acid with potential for use in biopreparation and/or in further finishing stages (Wu et al.), and a study of the degumming of bamboo to access a potential new fibre source for textiles (Fu et al.) is described.


Abstract We provide sufficient conditions for a Banach space-valued function to be scalarly bounded, which do not require to test on the whole dual space. Some applications in vector integration are also given.


Abstract The objective of this study was to compare the characteristics and bonding performance of phenol-formaldehyde (PF) resins modified and blended with crude bio-oil. For modified PF resins, c...


The observation of room‐temperature epitaxy of vapor‐deposited thin Ag films on Si(111) accomplished under conventional vacuum conditions is reported. Epitaxy was also observed at 350 °C. The films were deposited using a partially ionized beam deposition system, and were typically 1500 A thick. Epitaxy was confirmed via pole‐figure analysis. Scanning electron microscopy revealed excellent surface flatness even for the room‐temperature films. Contrary to previous observations, the growth was found to proceed by the layer mode, even at the elevated temperature. This change in morphology is attributed to the enhanced density of nucleation sites due to the energetic ions.


Abstract This chapter demonstrates a workflow to characterize the impact of heterogeneity in paralic deposits from full field to core scale that can be used for meeting the challenges of managing reservoir performance complexity in a supergiant field. The Upper Burgan member of the Cretaceous Burgan Formation was deposited in a tide-dominated coastline, which laterally passes into transgressive shoreface to offshore deposits. Variations in depositional subenvironments in time and space generated heterogeneity ranging in scale from millimeters to several meters (tens of feet) in the reservoir, which impact the permeability architecture of the reservoir. Construction of a sequence stratigraphic framework allowed understanding of the reservoir geometry and the extent of large-scale shale barriers. On the basis of variability in reservoir connectivity, the entire field was separated into three broad areas. A test case was run in an area of moderate reservoir connectivity to capture interwell heterogeneities. In the basal reservoir unit, a conceptual depositional model was developed through integration of regional geology, core-based sedimentology, and log motifs. The three-dimensional (3-D) depofacies volumes generated with the help of this model ultimately constrained the facies model. The defined object-based modeling (DOBM) method provided flexibility in modeling the mixture of facies that was used as a constraint to the petrophysical property models. Finally, micromodels for each reservoir facies were developed representing millimeter-scale heterogeneities. The facies classified from core interpretation and borehole images were incorporated to model heterogeneity at a high resolution. Streamline simulations were run to compute permeability anisotropy ratios in each facies. The results provided insight into the nature of heterogeneity within a framework of reservoir connectivity. They also provided high-quality input to larger simulation models and greatly influenced reservoir management. The methodology is applicable to other areas of varying connectivity.


The aim of our work is to develop and evaluate an ultrasound (US) technique to quantitatively measure and image the shear modulus of soft tissues in three dimensions (3D). It is widely recognized that breast tissue pathologies, such as neoplasia, often alter biomechanical properties. Thus, the intended application of our work is the detection and characterization of breast tissue lesions, via elastic modulus imaging, to improve the specificity of breast cancer screening. To that end, we have designed and characterized algorithms which 1) provide 3‐D motion estimates from 3‐D US images and 2) solve the 3‐D inverse problem to recover shear elastic modulus. The size and contrast accuracy of the reconstructed modulus distributions in tissue mimicking phantoms are presented. Inclusions as small as 5mm, some with contrasts marginally above unity, were successfully and clearly reconstructed. The effect of the boundary conditions and regularization methods on the reconstructed modulus images and the uniqueness of...


This research has been successfully synthesized three compounds of 1,3,5-triaryl pyrazole derivatives by two steps reaction. Firstly, pyrazoline (4a-c) compound was obtained by one-pot reaction of aromatic ketones, aldehyde and hydrazine in basic condition. Then, pyrazole (5a-c) compound was obtained by oxidative aromatization of compound 4 in the presense of acetic acid. Chemical structure of predicted molecules was confirmed by FTIR, NMR and HRMS spectroscopy data analysis. Antiproliferative activity of compound 5a-c were evaluated by in vitro assay against MCF-7 cells line and molecular docking simulation against ERα (PDB ID: 3ERT) using MOE 2019. Biological evaluation result showed that pyrazole compounds had weak antiproliferative activity against MCF-7 cells with IC50 were > 1000 µM, whereas the docking studies agrees the result.


This study examines three trust-building processes (relational, calculative, and institutional) that shapes individual trust in online firms and compares how the effects of these processes change over time as users gain experience with the target firms. It hypothesizes three alternative belief structures resulting from the above processes as determinants of trust, theorizes how their effects on trust change as users observe and learn from the firm's actual behavior, and empirically tests the hypothesized associations using data collected from a field survey of online banking users. The results indicate that relational, calculative, and institutional beliefs are significant drivers of trust. However, calculative and institutional beliefs have stronger initial effects than relational beliefs for new consumers of online firms. The effect of calculative belief on trust decreases with time, while that of relational beliefs increases and that of institutional beliefs remain relatively unchanged. Research and practical implications of these findings are discussed.


In this work, we examine unbalanced computation between an initiator and a responder that leads to resource exhaustion attacks in key exchange protocols. We construct models for two cryp-tographic protocols; one is the well-known Internet protocol named Secure Socket Layer (SSL) protocol,
and the other one is the Host Identity Protocol (HIP) which has built-in DoS-resistant mechanisms. To examine such protocols, we develop a formal framework based on Timed Coloured Petri Nets (Timed CPNs) and use a simulation approach provided in CPN Tools to achieve a formal analysis. By adopting the key idea of Meadows' cost-based framework and re¯ning the de¯nition of operational costs during the protocol execution, our simulation provides an accurate cost estimate of protocol execution compar-
ing among principals, as well as the percentage of successful connections from legitimate users, under
four di®erent strategies of DoS attack.


In this paper we study some properties of the Helton class of an operator. In particular, we show that the Helton class preserves the quasinilpotent property and Dunford's boundedness condition (B). As corollaries, we get that the Helton class of some quadratically hyponor- mal operators or decomposable subnormal operators satisfles Dunford's boundedness condition (B).


Nanocrystalline and nanocomposites of (Mn0.6Zn0.4Fe2O4)(1−z)(SiO2)z (z=0.0,0.10,0.15,0.25) were prepared by sol-gel method. The as-prepared samples were annealed at 200, 400, and 600 °C. The crystallographic phases, particle sizes and their distributions, etc. of the annealed samples were determined by x-ray diffraction and high-resolution transmission electron microscopy (TEM). Zero field cooled (ZFC) and field cooled (FC) magnetizations of some selected samples measured in the temperature range of 300–5 K suggest the presence of superparamagnetic (SPM) relaxation in the samples. For a few selected samples particle sizes were also estimated from the TEM micrographs and dc magnetizations. The particle sizes, magnetic anisotropies and blocking temperatures of some samples have also been computed from the difference of FC and ZFC magnetizations data. The particle sizes of the samples were also worked out from the Langevin fitting of the anhysteretic magnetization curve above the blocking temperature. The SP...


Objective: To highlight the clinical findings and rates of fetal outcome among women exposed to human parvovirus B19 infection in pregnancy, from a district general hospital in United Kingdom. Materials and Methods: Retrospective study of pregnant women referred to district general hospital in United Kingdom, for possible parvovirus B19 exposure between January 2007 and April 2013. All patients with suspected exposure to parvovirus B19 infection had serological investigations and were followed up with hospital protocol. For women with documented maternal infection, the fetus underwent serial ultrasound evaluations. When ultrasound demonstrated evidence of fetal hydrops women were referred to tertiary fetal medicine unit. Results: A total of 335 pregnant women were exposed to parvovirus B19 infection between January 2007 and April 2013. Of these, 213( 63.5%) had IgG antibodies and were immune. In 122 women, no IgG antibodies were detected giving the nonimmune incidence of 36.5 % for parvovirus B19 infection. Of the 122 nonimmune women, there were 24 cases of serologically documented parvovirus B19 infection and this represented a rate of infection of 18.8% following exposure to B19 infection. Of the 24 women,18 tested positive for IgM on their first visit and 6 were seroconverted between blood samples. Among these 24 infected women four had poor obstetric outcome in the form of intrauterine fetal death (IUD) at 16, 19, 26 and 30 weeks respectively. This gave a frequency of 16% for inutero fetal demise. Conclusions: Most women with B19 infection in pregnancy had satisfactory outcome, but there was substantial risk of fetal loss. Therefore there is need for enhanced surveillance of maternal parvovirus B19 infection. Local hospital policies should be developed for maternal screening of B19 infection and to correctly manage pregnancies at risk.

Mechanical vibration signal can reflect the running state of on-load tap-changer. In order to realize effective mechanical fault diagnosis for on-load tap-changer, a fault diagnosis method based on the parameter-adapted Variational Mode Decomposition (VMD) and Extreme Learning Machine optimized by Simulated Anneal (SA-ELM) is proposed. Firstly, the signal is decomposed by VMD method, and the number of modals is selected based on energy criterion. A group of modal components with narrow band and great discrimination is obtained. Then the energy features of each modal component are calculated, which form the feature vector group, and the modal features of different fault states are clearly distinguished. Finally, the feature vector group is inputted to the extreme learning machine (ELM) optimized by simulated annealing algorithm to realize the recognition and fault diagnosis of the vibration signals. An experiment is carried out on the simulation experiment platform and the collected signals are processed. Compared with the method based on VMD and ELM, the fault diagnosis method proposed can effectively improve the diagnostic accuracy of mechanical fault of on-load tap-changer.


In the past, adoption of the learning management system (LMS) has been voluntary with a limited amount of training at the micro level within a particular university of technology.  From discussions with academic staff it emerged that across the entire institution approximately 10-15% of academic staff used a particular LMS with only about 5% actively engaged. As the particular university progresses its broader plans for teaching and learning enhanced by technology, the LMS will become increasingly important as a tool to help realise the university's goals. The aim of the article is to gain a clear understanding of the potential barriers and obstacles encountered when implementing an LMS at a macro and meso level where the information technology system is weak. The article includes a discussion on a framework in support of the development of the LMS at a macro and meso level within a university of technology.

The full role of exotoxin in the pathogenesis of systemic staphylococcic infections has not yet been demonstrated. 1 The symptoms of systemic infections in human beings due to toxigenic staphylococci differ from the symptoms of those due to nontoxigenic staphylococci, 2 and this difference is sufficiently pronounced to make it possible to determine from clinical characteristics alone whether the symptoms are primarily due to the effect of staphylococcic exotoxin. 2d Previous reports have described the clinical response of the rabbit 3 and more specifically of the rabbit heart 4 to the intravenous injection of exotoxin. With these clinical and experimental reports as a point of departure, the purpose of the present work is to extend these observations by comparing the clinical and electrocardiographic responses in rabbits receiving intravenous injections of staphylococcus exotoxin and toxinfree suspensions of living toxigenic or nontoxigenic staphylococci. METHODS Rabbits averaging 2,300 Gm. in weight were used.

It is generally assumed that sanctions against male deviants are more severe than sanctions against female deviants. This paper tests two hypotheses which state that the differences in sanctions vary depending on the functional importance of sex roles and on inherent behavioral differences between males and females. Results based on approximately 10,000 voluntary and involuntary admissions to Tennessee state mental hospitals support the hypotheses. They also reveal that the effects of functional importance of sex role and sex-related behavior vary depending on the social context (hospital or community) andlor degree to which the behavior is deviant. Although findings generally support the societal reaction perspective of deviant behavior, they indicate that propositions about interactions among contingencies need to be incorporated in the perspective.


In this paper, the effect of the equal gain combining (EGC) spatial diversity for the free space optical (FSO) link for the new hybrid pulse position modulation binary phase shift keying subcarrier intensity modulation (2-PPM-BPSK-SIM) scheme in a turbulence channel is investigated. The analytical unconditional bit error rate (BER) of 2-PPM-BPSK-SIM with the EGC diversity under lognormal and negative exponential channels is investigated and a computer simulation is carried out to quantify the diversity gain. The results are compared with the BPSK-SIM modulation scheme. The results show that the EGC diversity offers a significant optical power gain and 2-PPM-BPSK offers improved performance to BPSK-SIM.


In order to study the fluid flow characteristics of the key components in hydraulic excited rotary valve,and then determine the area where the vortex and negative pressure to find the weak link in th e structure and analyze the performance of the valve. Simulate the flow field in the rotary valve by Fluent fluid analysis software, and setting different opening degrees under the same boundary condi tions. Studies showed that the velocity at the exit junction of the fluid in the rotary valve, and the vortex degree of pressure is large at the oil groove. When the opening degree is small, the nega tive pressure is large, the vortex is obvious. With the opening becomes large, and the negative pressure and the vortex are improved. The research provides a theoretical basis for the optimization and improvement of the rotary valve. Studies have shown: The velocity of the flow channel calculated under the turbulence RNG k − ε model is the largest, Realizable. The velocity of the flow channel calculated under the model is the smallest. For different models, the values of the low speed region are different, where Realizable k − ε Minimum model speed, The RNG k − ε model has the highest speed and standard. The speed of the k − ε model is in the middle; The high speed area is mainly concentrated in the corner area of the oil tank and valve mouth, The area of high speed area of the RNG k − ε model is smaller than that of the other two models, and the standard of the model is smaller than that of the other two models. The k − ε Model and the Realizable k − ε is no significant difference in the area of high speed area calculated by the model. The comparison draws the following conclusions: The results of the turbulence RNG k − ε model and the other two groups of models are more accurate when calculating the low velocity flow field. The Realizable k − ε Model and the RNG k − ε has the calculation results of the model are similar.

that he wished "to make some beginnings of Biblical criticism in England,"2 he expressed a desire which had been stimulated by his contacts with a particular kind of German theologian. This desire was later implemented by many of the Broad Churchmen and by Matthew Arnold. I propose here to point out that Thomas Arnold's knowledge of these Germans conditioned much of his religious thought, changed some of his opinions, and gave him specific materials for his writings, and that both he and his son were aware of the nature and direction of

Abstract : The Berthing and Utilities Requirements Forecasting (BURF) Program is a management tool designed to determine the berthing requirements for the naval shipyards over a long-range period. The berthing utilities considered by the program are linear space (ft), electric current (ac at 450 volts), fresh and salt water (gpm), and steam power (lb/hr). Given the ships to be berthed in a shipyard for any one day, the system will assign selected ships to berths and forecast the resulting utilities requirements at that yard for that day. By choosing appropriate peak days over the long-range period, an overall forecast for a yard can be produced. (Author)

Abstract Begonia jocelinoi Brade (Begoniaceae) is a threatened species, endemic to a small locality in the Brazilian Atlantic Forest. The species was formerly listed as Wanted in the Red List of Endemic Flora of the state of Rio de Janeiro because it had not been recorded since 1953. After evaluating herbarium collections and conducting fieldwork during May 2019–February 2020, we report the rediscovery of a single population of 65 reproductive individuals of B. jocelinoi, along with numerous seedlings, besides a trail in Itatiaia National Park. This Park is an IUCN category II protected area that permits some tourism activities. Some individuals of B. jocelinoi showed signs of pruning following the maintenance of the trail. We recommend strategies for in situ and ex situ conservation of this narrowly endemic species, including provision of advice to tourists regarding the occurrence of threatened species, and diversion of the trail where the species occurs.


To explore sociological implications of environmental hazards arising due to industrial pollution on industrial workers during their work in the environment they work and also to find out whether it affects their social and other associated behaviors in an industrial organization. The study is based on exploratory cum descriptive study design and the cross-sectional data. The analytical sample consists of 500 workers from all three stratified categories- skilled, semi-skilled and unskilled and using univariate analysis method the data has been analyzed.
We found that industrial workers are clearly showing their concerns arising due to environ-mental hazards at their work place and they indicate several implications because of situation in which they work. Majority of sampled workers were found in favour to enhance the level of knowledge of awareness regarding environmental hazards and repercussions.


55 pregnant women in gestational age from 6 to 12 weeks divided into 3 groups were investigated: 20 healthy women, wishing were taken as conforms to interrupt pregnancy by a method of a surgical abortion, 15 with incipient abortion and 20 with missed abortions.

Here was stratistically significant difference of some enrymes activities in conglicated fregnan-cies vs control. The decrease of lysosomal enzymes activity in chorionic tissue and placental bed, indicating on deviations of molecular mechanisms of enzyme homeostasis regulation, in particular, programmed cellular destruction, can be one of the basic parts of cytotrophoblast invasion distruc-tances ae early stages.


Die Opferung/Bindung Isaaks, Bd. 2, Gen. 22, 1-19 in fruhen rabbinischen Texten, by Lukas Kundert. WMANT 79. Neukirchen-Vluyn: Neukirchener Verlag, 1998. Pp. x + 218. DM 98.00. This book pleasantly surprised me. The modern trends in North American books that investigate midrash generally deal with literary analysis or sociology but rarely with midrash in its own right. This book does precisely that and therefore it deserves just recognition. As a work of scholarship there is much to admire in it. The translations are precise, except for a few awkward literalisms and some other minor quibbles. The texts are based on the best manuscript evidence available and the Hebrew originals and German translations are lined up admirably. The summations of past scholarship that are pertinent to the book's topics are excellent. The discussions of the passages are intelligent, cogent, and as good as anyone else might venture. In sum, this short work (without the Hebrew columns the book would be considerably shorter) accomplishes what the young, thirty-year-old author intended it to do. It deals with the issues pertinent to midrash through a thorough examination of rabbinic traditions dealing with Abraham's "binding of Isaac" trial in the Talmuds and midrashic compilations. Kundert tells us what we need to know about dating textual traditions, determining the sense of rabbinic usages of Hebrew, understanding midrashic methods, tracing materials through earlier writers such as Josephus and Philo, and deciding the best readings among various manuscript families. He clarifies the theological motifs that lie hidden in these texts. He is to be congratulated for spending so much energy upon details in arcane and archaic texts in a world of scholarship that is deplorably indifferent to these "trivial details." It is precisely upon these details that the entire edifice of academic research into the writings of the ancient rabbis should depend. I particularly appreciated his efforts to show how some Christian writers are misguided in regard to what is authentically Jewish. The author illustrates how midrash establishes its models in thoroughly Jewish contexts. His overviews, presentations of text, and commentaries provide an excellent venue to appreciate his careful detailing of pertinent features in the many texts he examines. His introduction and conclusions are to the point, as are his notes and annotations. He provides very thorough indices. Nevertheless, the book suffers from atrocious Hebrew typesetting. The typesetter mistook similar looking letters of the Hebrew alphabet and too often confused them for each other. Also, the scribal abbreviations in the manuscripts should have been noted as to what they signify because nonspecialists will certainly be confused by the conventions of medieval copyists. I was not overly troubled by mistakes here and there in the translation of simple words that have specialized usages in rabbinic Hebrew because they are generally innocuous and such things happen to the best of us. …

----------------------------------------------------------------------------------------------------------------------------------Abstract: Over the past decades, the demand for digital information has increased dramatically. Even in food industry, consumers are using the digital information to better inform themselves. As a result they have started expecting lesion free, good quality fruits, vegetables and other items at lower cost. In food industry external quality of fruits play an important role which is evaluated by their colour, texture and visual lesions. Manual inspection is time consuming, expensive and non consistent, therefore machine visions approach is adopted for lesion detection. Here in this paper mangoes are selected as a case study where different segmentation techniques are used for detection of lesion areas in mango. Recommendation of the best suited segmentation method for defect tracking is adopted. The proposed system is evaluated using defected mangoes. About 100 samples of mangoes examined and about 30 lesion mangoes were selected for the segmentation process.

In contrast, Bulliet's discussion of the growth of the hadith and "the roots of religious authority" is banal and grossly undersubstantiated. It fails even to mention the vigorous recent scholarship in the field of hadith studies and early development of Islamic law. Without bothering to check either the isnad or the variants of the texts as transmitted by different schools, he merely cites a number of "local" hadiths, which he presumes to have been transmitted not through the centers (schools) of hadith but produced and preserved locally, "on the edge." The logic of Bulliet's argument is hardly convincing enough to justify his disdain for the current scholarship in the field. Noting the numerical preponderance of the hadiths on ritual matters, in contrast to the hudud and "issues of governance (ahkam)" Bulliet asserts that these ritual matters are "exactly those areas of greatest concern to new Muslims trying to integrate themselves into the community" (p. 32, and further, pp. 86-88). This, together with the fact that only some 10 percent of the hadith students' travel led beyond their local center of learning (p. 85), is taken to establish that the hadith was "local knowledge." But why on earth would these ritual matters be of any less interest to the old Muslims and to the inhabitants of Arabia and Iraq? And does the transmission of translocal knowledge require more than one teacher to travel to a center of learning? Bulliet seems to be on solid historical ground in showing the social consolidation of the ulama as local elites, but this tells us next to nothing about the transmission of knowledge. Chapter 9 bridges the centuries between the medieval period and contemporary Islam, which is the subject of the final chapter. Even with the author's help in supplying a title, "The View from the Edge Today," I fail to see the relation between the main study and the final chapter, which is presumably the focus of Columbia University Press's promotional blurb: "Today's Islamic activists, as well as potentates such as Muammar Qaddhafi, Hafez al-Assad, and Saddam Hussein, have established their authority not by appealing to the progressive cultural values of the West, but rather to Islamic religious tradition." In short, this is not a work of weighty scholarship. Judging by the acknowledgments in the footnotes (p. 213 n. 17, p. 218 n. 34), some of the crucially relevant points have not been systematically investigated, but rather added as afterthoughts on the basis of the material brought to the professor's attention in comments on earlier drafts. References to the secondary literature, other than unpublished Columbia University dissertations, are also relatively few. Bulliet's excathedra historical conjectures are not uninteresting, but he should not have disdained the painstaking firsthand research required to substantiate them.

In an open network, how to provide deterrents to malicious behaviors is an important issue. A common solution is the use of cryptographic primitives. In this solution, execution logs are stored by each entity and used when needs arise for trouble settlement or judgment; authorities are involved mainly in the settlement phase. Depending on system-design and security policies, however, more active authorized procedures would be of great help. In preparation for such a situation, this paper introduces a framework of an inspection mechanism for server-and-client protocols which are based on a private-key cipher. The mechanism uses two "current" private keys per server-and-client pair. One of them is updated session by session and thus the system can accept one-session rental of the membership; voluntary clients can lend their membership to the inspection authority without disclosing the current keys of the next and future sessions. As an application example, a digital-valuable storage system called an "electronic safe-deposit box" is described and its protocol is shown in part.


Shear failure of exterior beam-column joints is identified as the principal cause of collapse of many moment-resisting frame buildings during recent earthquakes. Effective and economical strengthening techniques to upgrade joint shear resistance and ductility in existing structures are needed. In this paper, efficiency and effectiveness of carbon fiber-reinforced polymer (CFRP) sheets in upgrading the shear strength and ductility of seismically deficient exterior beam-column joints have been studied. Four as-built joints were constructed with nonoptimal design parameters (inadequate joint shear strength with no transverse reinforcement) representing preseismic code design construction practice of joints and encompassing most of existing beam-column connections. Out of these four as-built specimens, two specimens were used as baseline specimens (control specimens) and other two were strengthened with CFRP sheets under two different schemes (strengthened specimens). In the first scheme, CFRP sheets were epo...


Health promotion has many facets and one of the most important is empowerment, helping individuals or communities to take decisions which may well lead to better health. The very term 'empowerment' is broad and could include issues which are not typically associated with health promotion. For eXdI11p1C, I chanced across a scheme to help orphans in Uganda, whose parents have died as a result of the AIDS epidemic sweeping through Africa. One of the difficulties faced by orphaned children is the loss of property rights. The future is bleak for children without shelter or any land to grow food. However, in Uganda, a project sponsored by the charity Plan International UK' trains community volunteers as'parale~als'to go out into villages and protect the rights of orphans. Such an initiative helps protect these vulnerable children and will reduce potential suffering. In addition, the volunteers give advice about HIV, in particular how the virus is spread. So here is a project which would not necessarily be linked to health promotion but is certainly as valuable as any narrowly health based intervention. One of the major difficulties for Africa and AIDS is to convince international donors and some local politicians that AIDS related diseases have wiped out a generation of parents. Clearly more resources are required to help defeat this major health problem. It is interesting to note that in the West, coronary heart disease is one of our major health problems and yet the majority of the population and even some health professionals, may not have a clear understanding of the risk factors. A recent publication' from the National Heart Forum addresses this problem of helping individuals to consider changes


Ethyl methyl sulfonate (EMS) treated leaf explants were grown in vitro on MS medium fortified with BA (8.88 µM) and NAA (2.69 µM). A total of 24 mutants including 4 dwarf mutants, 7 leaf mutants and 13 flower mutants, selected in IM1 culture generation, were analyzed at morphological, phytochemical and molecular level. Morphological analysis of mutants revealed significant variation in plant height (18.6 to 42.3 cm), internode length (2.2 to 5.82), leaf size and morphology, number of inflorescence (4 to 10), flower colour (white to violet) and phytosterol content (0.033 to 0.0467 mg/g). RAPD analysis involving 30 primers generated 185 amplified products; of which, 86 (46.73%) were polymorphic in nature. Jaccards similarity coefficient matrix between mutant lines inter se and with control plant ranges from 0.636 to 0.881. UPGMA based unrooted tree grouped all 24 mutant lines and control plant into two major clusters, which were sub-clustered into four, and the pattern well corresponded to the flower colour as well as phytosterol content data baring two mutant lines ALM-12 and ALM-13.


This study considers how sustainable consumption practices are brought into relationship with other things, people, and ideas that inhabit the social space of consumers. The analysis of 10 existential phenomenological interviews reveals that self-confessed green consumers acknowledge a similar understanding of environmental degradation but experience sustainable consumption differently. For some, the practice requires hardship and is experienced as a daily struggle. For others, sustainable consumption naturally occurs as part of their social life. The concept of personhood helps understand the informants' contrasted roles, rules, and symbolics of sustainable consumption. The findings highlight that sustainable consumption is integral to the same social and cultural system that enables people to relate to one another and that promoting categories of green consumers and criteria for their sustainable identity may contradict with a range of activities that are regarded as normatively important to our current consumer culture and central to our personhood.


In the field of media research, the beta binomial has performed very well for estimating the distribution of the frequency of exposures to a media vehicle. However, long-term projections have shown consistent biases. The beta binomial geometric model, an extension of the well-known beta binomial model, which incorporates non-stationarity of individuals' exposure probabilities, is able to account for these errors. In addition this beta binomial geometric framework provides insights into the sensitivity of various media statistics to non-stationarity. This model is a particular operationalization of Howard's general Dynamic Inference Model Howard, R. A. 1965. Dynamic inference. Oper. Res.13 2 712-733.. The paper focuses on applications to some television viewing and magazine readership data. The properties of the model, estimation of the parameters and statistical tests are also presented. Finally, some future research possibilities are discussed.


This essay attends to two poems by Susan Howe: 'Thorow' (1990) and 'Souls of the Labadie Tract' (2007). In doing so, it offers both an approach to reading an experimental poetics in transition, and a new angle on the question of what it might mean to hear a lyric voice coming to life in print. The essay situates Howe's early work in the milieu of American Language writing, before turning (after a glance to Fredric Jameson's aesthetic politics) to the sonic textures of her recent poetry.

CAS is responsible for proteolysis of ICAD and activation of endonucleases. Survivin (SUR) directly inhibits CAS. This study aimed to assess timeresolved changes of CAS and SUR expression and the subpopulations of CAS+/SUR+, CAS+/SUR–, CAS–/SUR+ cells in peripheral blood mononuclear cells in children with acute lymphoblastic leukaemia (ALL) in response to prednisone administration. The study comprised 26 children with ALL. Cytospins of mononuclear cells collected prior to and after 6 and 12 h of prednisone administration were stained with rabbit anti-CAS antibody followed by swine antirabbit IgG/FITC and mouse anti-SUR antibody followed by goat antimouse/APC. Cellular DNA was counterstained with PI/RNase. CAS-associated green fluorescence, SUR-associated long red fluorescence and PI-associated red fluorescence were measured by laser scanning cytometer. Values of CAS and SUR-bound fluorescence did not change significantly after 6 and 12 h after treatment, however the rate of CAS+/SUR– cells increased after 6 h after prednisone administration ( P < 0.05). Analysis of populations of CAS+/SUR– cells may contribute to better understanding of interaction of proteins promoting and inhibiting apoptosis. Abstract no.

The algorithm is based on gray-scale co-occurrence matrix. We could show that this procedure measures accurately the focus even under noisy and low-contrast imaging conditions with a small computation time even with low information content images. Focus function does not depend on any threshold allowing unattended operation for automated microscopy. We have compared our approach with different standard autofocusing methods and could show that it is a suitable and robust focus measure for use in fluorescence and bright-field microscopy that outperform similar methods. Our results indicate that this function is an optimal focus algorithm for a wide field of use including fully automatized algorithms. Abstract no.

In comprehensive 2D-LC, often referred to as LC x LC, the entire effluent from the first dimension (1D) is transferred to the second dimension (2D) and the sample is subjected to separation in both dimensions. Depending on how the 1D effluent is transferred to 2D, LC x LC can be further categorised into 'offline' and 'online' mode. Online LC x LC is the focus in this review, because in contrast to offline LC x LC, online LC x LC is faster, easier to automate, and is less vulnerable to sample loss or degradation. Compared to offline LC x LC, online LC x LC is more difficult to employ and has much higher requirements on hardware and software. Recent advances in 2D-LC instrumentation and software, especially recent commercial offerings have significantly reduced the time and expertise required for the development of industrial applications and was critical for the proliferation of the technique.


ABSTRACTTwelve hundred different problems, as described by project practitioners, are sorted according to an adaptation of the classic management functions first described by Henri Fayol: planning, scheduling, organizing, staffing, directing, and controlling. Observations include that planning problems are most prevalent, that some problems vary with project structure, and that some problems vary with success level. The most surprising lesson is that many types of problems are equally or even more prevalent on successful projects.


Population genetic diversity and structure in Ziziphora tenuior L.: identification of potential gene pools.-Genetika, Ziziphora tenuior L. is a medicinal plant species of the genus Ziziphora (Labiatae) that grows in different areas of Iran. In order to study the population genetic structure in Ziziphora tenuior ,we collected 107 plant specimens from 20 geographical populations that are located in 17 provinces. ISSR molecular markers were used for genetic diversity analysis. The populations studied revealed intra- and inter-population genetic variability. AMOVA test showed significant genetic difference among the studied populations. STRUCTURE plot identified two main gene pools for Ziziphora tenuior in Iran. These populations showed isolation by distance and restrict gene flow occurred among them.


Abstract One of the key questions of primary importance to global agriculture and food security is how to optimize sustainable intensification to balance competing demands on land for food and energy production, while ensuring the provision of ecosystem services and maintaining or increasing yields. Integrating trees and agriculture through agroforestry has been attracting increasing interest as an agroecological approach to sustainable intensification. Trees have traditionally been important elements of temperate agricultural systems around the world, but there has been increasing separation of agriculture, forestry and nature over the past few decades. This paper discusses what we can learn from traditional agroforestry systems to help develop modern systems that integrate ecological farming and agroecological advances to achieve sustainable intensification. We also discuss the existing barriers to wider adoption of agroforestry, and identify how these barriers can be overcome to promote agroforestry as a mainstream land-use system.


The aim of this article is to analyze some of the reasons for the current discrediting of pedagogical knowledge. First, some national and international examples of the cultural circumstances for the rejection of Pedagogy as an academic discipline and pedagogues as valid professionals are established. Secondly, a review of the main positions at stake on anti-pedagogism is presented. Thirdly, some of the reasons that may explain the current anti-pedagogim are analyzed. These reasons are based on possible mistakes or excesses of a certain kind of Pedagogy. There are political reasons; Pedagogy has allowed an excessive ideological polarization between traditional schools and progressive or new schools. There are gnoseological reasons as well; Pedagogy has separated way too much the educational perspective and the learning from the cultural content in the curriculum areas. And, finally, there are normative reasons too; Pedagogy has focused excessively on identifying education with life and subjective experiences.


In this study, we have developed taste and other functional enhancements of yam chips, from tasteless and flavorless yam slices, through the process of soaking freeze-dried yam in different commercially available juices, including apple, omija (fruit of Maximowiczia typica), grape, wild grape, orange, tomato, red ginseng, and black garlic juice. The analyses of color (brightness, redness and yellowness), pH, brix, acidity, total polyphenol, total flavonoids, total sugar and reducing sugar, DPPH and ABTS scavenging activity, reducing power and nitrite scavenging activity, of the different yam chips showed that the freeze-dried yam slices absorb various components of fruit juices, such as flavonoids, sugars, organic acids and flavors, during the soaking process. These changes resulted in increased taste (both sweet and sour tastes), flavor and antioxidant activity in the yam chips. The soaking time for yam slices in juice is considered to be a crucial factor for the taste and bioactivity of yam chips. In the case of grape juice-yam chips, which had the highest preference among the 8 different chips, the optimum soaking time was noted as 120 seconds. The optimization of the soaking process is necessary for various juices. These results suggest that taste, and other functional enhancements, in yam chips can be developed by juice-soaking and freeze-drying methods.


Neuropathic pain is a kind of chronic intractable disease. HBO explored the involvement of mitophagy which is associated with energy metabolism by AMPK. CaMKKβ/AMPK signaling pathway may involve in mitophagy process. We randomly divided mice into four groups: C, S, CCI, and CCI + HBO group. Pain-related behaviors were evaluated using mechanical withdrawal threshold and thermal withdrawal latency analysis. Western blot was employed to assess expression of CaMKKβ, pAMPK, AMPK, NIX, BNIP3, and Drp1. Spinal cord was observed under the electron microscope. Immunofluorescence changes in NeuN and CaMKKβ or AMPK were examined. AMPK inhibitor compound C (CC) and CaMKKβ inhibitor STO609 were administrated prior to CCI, respectively. The changes in behaviors and Western blot are examined. HBO upregulated CaMKKβ and pAMPKα expression. NeuN and CaMKKβ were colocalizated in immunofluorescence. HBO can elevate the pain-related behaviors significantly, while it was downregulated by CC or STO609. HBO upregulated NIX, BNIP3, and Drp1 expressive level more significantly than those in CCI group. However, expression was reduced when CC or STO609 were administered. Electron microscopic examination showed that mitophagy was upregulated after HBO treatment. This phenomenon was not observed when CC or STO609 were administered. Our findings suggest that CaMKKβ/AMPK pathway maybe a potential signal pathway on analgesic mechanism of hyperbaric oxygen via mitophagy.

In a recent paper, a new discrete-time Bayesian filter, named the cubature Kalman filter (CKF), was derived. To reduce the complexity of the filter, we propose in this paper to combine the CKF with the linear Kalman filter, when either the process equation or the measurement equation is linear. The resulting filter is referred to as the Reduced CKF (RCKF). It is here applied to the problem of tracking in Cartesian coordinates a moving object whose state can be modeled by a linear dynamic equation, but whose measurement equation is non linear, due to the fact that the measurements represent position measurements in polar coordinates. The simulations results show that, in terms of root Mean Square Error (RMSE), the RCKF and CKF have the same performance, but the processing time of the RCKF is lower than that of the CKF.


A BSTRACT : Inflation produces adverse effects to growth in economies. However, economic analysis faces a problem of determining the threshold at which inflation becomes harmful to the economy. In this article we try to determine the inflation rate favorable to growth or not for the CEMAC countries and to make contributions to economic policy.

DNA has been used as a nano building material since the 1980s. Protein nanostructures have the potential to give greater geometric control and shape variability. Gonen et al. describe the computational design of proteins that self-assemble into two-dimensional arrays. These programmable protein lattices should enable new approaches in biomolecular structure determination and molecular sensing.

Inertial frames and Lorentz transformations have a preferred status in the special theory of relativity (STR). Lorentz transformations, in turn, embody Einstein's convention that the velocity of light is isotropic, a convention that is necessary for the establishment of a standard signal synchrony. If the preferred status of Lorentz transformations in STR is not due to some particular bias introduced by a convention on signal synchronism, but to the fact that the Lorentz transformation group is the symmetry group of the theory, then the signal synchronism is not a matter of convention but rather a matter of fact. In order to explore the conventionalist thesis, that within the frame of STR isotropy in the velocity of light and, hence, signal synchronism is a matter of convention, we need a generalized Lorentz transformation group that does not embody Einstein's isotropy convention, and upon which STR can be based. We present here a new approach to the resulting search for a generalized STR, which is well suited for establishing some well-known results of Winnie as well as some new results.

Cupriavidus necator H16 is a chemolithoautotrophic Gram-negative bacterium that belongs to the class of -proteobacteria. In recent years, it has attracted the biotechnological attention as a cell factory to produce value-added chemicals. Thus, a need for expanding engineering tools for chemical production in C. necator H16 has emerged. In order to use C. necator H16 as a cell factory, mainly two different engineering strategies are reviewed in this work: rational design engineering and evolutionary engineering.

Aim:

The overall aim of the study is to engineer C. necator H16 with rational design and evolutionary engineering tools to explore the biotechnological potentials of the strain and fine-tune the properties of C. necator H16 for chemical production using waste stream as a feedstock.

Thesis content:

In Chapter 1, literature review about C. necator H16 was compiled to understand the natural metabolism of the strain and to analyse its different biomanufacturing potentials, as well as engineering strategies used for chemical production in C. necator H16 and other related microorganisms, afterwards, in Chapter 2 the development of an optimised transformation method and a synthetic biology toolbox for C. necator H16 was developed to design robust strains of C. necator H16. Once the synthetic biology toolbox was tailored for C. necator H16, in Chapter 3, the synthetic biology toolbox was tested for the expression of two clusters of genes as well as possibly obtain bioproducts from the expression of these. Then, in Chapter 4, evolutionary engineering tools were optimised to engineer C. necator H16, the evolutionary engineering tool used was directed evolution via random mutagenesis, where an optimised protocol for random mutagenesis with a chemical mutagen for C. necator H16 was optimised and used to try to understand the biotin biosynthesis pathway of C. necator H16, which could furtherly be used for chemical production. In Chapter 5, the knowledge and strategies studied in previous chapters and proven to work in C. necator H16 supported the approaches selected to construct recombinant and evolved strains of C. necator H16 for chemical production (bioplastics) using waste stream (crude glycerol) as a feedstock. Chapter 6 highlights the general discussions, results, future work and perspectives of this PhD work.

Abstract Six field experiments were conducted to investigate any interaction between pyroxasulfone and flumioxazin on soybean tolerance and control of multiple-herbicide-resistant (MHR) waterhemp in soybean during 2016 and 2017 in Ontario, Canada. There was a synergistic increase in soybean injury with the co-application of pyroxasulfone and flumioxazin at all rates evaluated at 2 wk after emergence (WAE), the two highest rates evaluated (134/106 and 268/211 g ai ha–1) at 4 WAE, and the highest rate (268/211 g ai ha–1) evaluated at 8 WAE. Soybean injury with all pyroxasulfone and flumioxazin treatments was transient and had no adverse effect on soybean grain yield. Pyroxasulfone applied preemergence at 45, 89, 134, and 268 g ai ha–1 controlled MHR waterhemp up to 72%, 89%, 92%, and 95%, respectively. Flumioxazin applied preemergence at 35, 70, 106, and 211 g ai ha–1 controlled MHR waterhemp up to 78%, 90%, 93%, and 96%, respectively. Pyroxasulfone/flumioxazin applied preemergence at 45/35, 89/70, 134/106, and 268/211 g ai ha–1 controlled MHR waterhemp up to 92%, 96%, 98%, and 100%, respectively. There were no significant antagonistic or synergistic interactions for the control of MHR waterhemp with pyroxasulfone/flumioxazin at rates evaluated except at 268/211 g ai ha–1, which provided a synergistic increase in MHR waterhemp control at 4 WAE. The MHR waterhemp biomass and density reductions followed a trend similar trend to visible control. Pyroxasulfone/flumioxazin at 268/211 g ai ha–1 caused a synergistic response in biomass reduction (9% difference). Based on these results, there is an additive increase in MHR waterhemp control and potential for a synergistic increase in soybean injury with the co-application of pyroxasulfone plus flumioxazin. Nomenclature: Flumioxazin; glyphosate; pyroxasulfone; waterhemp; Amaranthus tuberculatus (Moq.) J.D. Sauer; soybean; Glycine max (L.) Merr.


The task of root-finding of the non-linear equations is perhaps, one of the most complicated problems in applied mathematics especially in a diverse range of engineering applications. The characteristics of the root-finding methods such as convergence rate, performance, efficiency, etc., are directly relied upon the initial guess of the solution to execute the process in most of the systems of non-linear equations. Keeping these facts into mind, based on Taylor's series expansion, we present some new modifications of Halley, Househölder and Golbabai and Javidi's methods and then making them second derivative free by applying Taylor's series. The convergence analysis of the suggested methods is discussed. It is established that the proposed methods possess convergence of orders five and six. Several numerical problems have been tested to demonstrate the validity and applicability of the proposed methods. These test examples also include some real-life problems associated with chemical and civil engineering such as open channel flow problem, the adiabatic flame temperature equation, conversion of nitrogen-hydrogen feed to ammonia and the van der Wall's equation whose numerical results prove the better performance of the suggested methods as compared to other well-known existing methods of the same kind in the literature. Finally, the dynamics of the presented algorithms in the form of polynomiographs have been shown with the aid of computer program by considering some complex polynomials and compared them with the other well-known iterative algorithms that revealed the convergence speed and other dynamical aspects of the presented methods.

The band gap energy was calculated by UV-Vis-NIR and structural property by FT-IR spectroscopy. The results obtained from the study confirm the formation of nickel oxide nanomaterial with the particle size of 25 nm.


This paper presents an approach for distance mea-surement between two smartphones. The approach uses the smartphone's microphone(s) and speaker(s) to simultaneously emit and record audio to determine the propagation delay, and hence distance. Each device in succession emits a unique maximum length sequence (MLS) audio signal. Both devices record emitted signals in a single continuous recording. An automated comparison of the recordings from both devices - and specifically the temporal position of the emitted signals within each recording - allows the audio propagation delay between the devices to be estimated. A custom web application was developed that performs signal emission and recording on each device and transmits the resulting recordings to a master device for automated analysis. This facilitates vendor and operating system independent deployment. Initial tests, carried out using Samsung Galaxy A10 smartphones running Android 10, yielded a mean error of 32.29 mm. Because the distance is determined by the propagation delays in each locally acquired audio, there is no need for clock time synchronization. Possible future refinements of the system are discussed, including representation of the positions of microphone and loudspeaker within each phone, that may significantly improve precision. Accurately determining the distance may also aid time mismatch correction.


The objective of the study was to assess the impact of water oxygen concentration and ambient light on the success rate of egg development until hatched rainbow trout (Oncorhynchus Mykiss, Walbaum, 1792) as well as the success rate of artificial fertilization according to the freshness of the ova (in vitro aging) of the spawners of the Ras Al Ma salmon farming station. The results obtained show that the mean success rate varies between 73% and 69% of the eggs development depending on the oxygen concentration, 76% for the eggs incubated in the dark versus 47% only for the eggs exposed to ambient light. With regard to fertilization success rates according to their freshness (t0, t1, t2, t3 and t4 hours), the results showed that it is about 71% for the fertilized eggs just after being collected from spawners and gradually decreases to reach only 30% four hours after the stripping.


Natural conditions in the circumpolar region are unfavorable for the residents who live there because dermatologists have developed a special technique for general practitioners to early identify skin problems that occur in residents living in the Arctic region. For preliminary diagnostics, we developed a device that allows you to assess the risk of a disease in a patient, send the resulting image to a specialized oncology clinic for decision-making. In addition, the device allows you to save archives of photographs so that a general practitioner can observe the problem in dynamics from 6 to 12 months. This technique allows you to identify skin problems at an early stage and help the patient recover.
