Graphene continues to attract considerable attention from the materials science community through its potential for improving the mechanical properties of polymer thermosets, yet there remains considerable uncertainty over the underlying mechanisms. The effect of introducing graphene sheets to a typical thermosetting polymer network on mechanical behaviour is explored here through concurrently coupling molecular dynamics with a finite element solver. In this multiscale approach, Graphene is observed to act in two ways: as passive microscopic defects, dispersing crack propagation (high deformation); and as active geometric constraints, impeding polymer conformational changes (low deformation). By contrast, single‐scale atomistic simulations alone predict little measurable difference in the properties of the graphene‐enhanced epoxy resins as compared with the pure polymer case. The multiscale model predicts that epoxy resins reinforced with graphene nanoparticles exhibit enhanced overall elastoplastic properties, reducing strain energy dissipation by up to 70%. Importantly, this is only observed when taking into account the complex boundary conditions, mainly involving shear, arising from coupling physics on length scales separated by five orders of magnitude. The approach herein clearly highlights a novel role of graphene nanoparticles in actively constraining the surrounding polymer matrix, impeding local dissipative mechanisms, and resisting shear deformation.


A 16 μm CF 4 laser oscillator has operated continuous wave in a cooled static cell. Pump powers required from the low-pressure continuous wave CO 2 laser were approximately 3 W. The laser cavity was a multiple-pass off-axis-path two-mirror ring resonator. Unidirectional CF 4 laser power at 615 cm-1exceeded 2 mW. Rate equations were used to estimate scaling of this laser source. For modest pump powers (40 W) approximately 1 W of emission power is predicted from this small and simple system.

Author(s): De Jong, Maarten | Advisor(s): Asta, Mark | Abstract: This dissertation broadly describes efforts related to materials discovery, design and optimizationusing a first-principles approach based on density functional theory (DFT).The two main application areas comprise transition-metal alloys and functional materials.The research involving transition-metal alloys aims at finding cost-effective replacementstrategies for rhenium (Re). Elemental Re exhibits profuse deformation twinning undermechanical loads and has a high ductility. It is shown that the twinning characteristics ofRe and its ductility are correlated with its anomalously low (11-21) twin-boundary energy.The origin of this twin-energy anomaly is related to the presence of icosahedral structuralunits on the (11-21) twin boundary. These structural units are stabilized near d-band fillingscorresponding to Re. The (11-21) twin-boundary energy can be lowered further bydecreasing the d-band filling with respect to elemental Re. This increases the intrinsicductility according to three independent ductility parameters employed in this work: i)Pugh's ratio of bulk to shear modulus, ii) Yoo's ratio of surface to twin energy and iii) anideal-strength criterion. Based on new insights in the relation between d-band filling, defectenergies and intrinsic ductility, several candidate alloys for Re replacement are proposed.Ru-based alloys with additions of Ta, W and Re are shown to be potential replacementcandidates. The last part of this dissertation describes high-throughput calculations thathave culminated in the two largest databases of elastic and piezoelectric tensor propertiesavailable to-date. The workflow for doing such calculations is described, along with variouschecks to ensure the accuracy of the calculated physical properties. The database withelastic-tensor properties is expected to be of use in a number of fields where discovery ofnew materials with desired values of elastic stiffness or (lattice) thermal conductivity are ofinterest. Further, data mining and machine learning can be applied to better understandelastic properties and their physical descriptors. Several novel piezoelectric materials arediscovered as part of this work. Some of these exhibit a high intrinsic piezoelectric responseand may serve as a starting point for a process in which the piezoelectric response is optimizedby alloying and microstructure engineering. As such, this database can support a search for future replacement candidates of the widely used piezoelectric materials such as Pb(ZrxTi1?-x)O3 (PZT) that contain lead.


Air transport in Romania is far behind in other EU countries, even if the demand for this type of transport is steadily increasing. A special situation is the air transport in the Dobrogea region, which is far behind the other regions of the country. In this paper an analysis is made of the situation of passenger transport and cargo transport in the counties of Constanta and Tulcea. In the current context of increasing demand for air transport, a number of strategies and measures are needed to develop air transport in this part of the country.


Specifying and monitoring service level agreements (SLA) has been the subject of intensive research. However, methods of enforcing SLA have not addressed the specific issues of composite services (CS). Our work focuses on the problem of keeping prearranged SLAs for service workflows including workflows supporting long lived transactions (e.g. WS-BA). As a solution we offer scheduling of component service requests. The latter is based on regaining control over legacy services by means of transparent proxies and later scheduling of their invocations. Various heuristics based policies are evaluated under two different types of service level agreements. The policies vary from the simpler, operating only on the base of business value, to the more complex which also consider Quality of Service requirements, topologies of workflows, utilization of components services, etc. The experiments conducted over the model, which precisely captures the behavior of web services, reveal the benefits of providing schedulers with various types of context.


Objective: Herbal drugs have been utilized for the treatment of infectious diseases as medicines since ancient times. Plant and their extracts used for the manufacturing of different dosage form design. Medicinal plant is comprised of different parts that include root, leaf, stem, flowers, bark that have a high level of microorganisms, bacteria, yeast and especially fungal molds.
Methods:The antimicrobial analysis conducted on herbal raw materials, Bulk, Extracts, we found less CFU/gm. and percentages of Total Aerobic Count in bulk and extracts because these are heated at extreme temperatures.
Results: We have observed no fungal growth in bulk and extracts so it is devoid of any spore and toxin formation.  In Raw materials, some molds were found that is similar with nonpathogenic strain that will not produces any toxin. It is understood, if the toxin producing mold growth is present in raw materials so the herbs, extract and excipient when combined together and converted into bulk products, by this technique all the toxins and dormant spores are killed at an extreme temperature i.e. 18°F to 20°F. The bulk is the semi-finished product and combination of herbal raw materials, extract, and excipient after testing it will go for final packaging and we get the finished product. The supplier/manufacturer of raw materials will reveal its purity that is accepted or rejected by quality control (Microbiology and chemical lab), Herbion Pakistan (Pvt) Limited, Karachi, Pakistan.
Conclusion: It was concluded that PolyHerbal Drugs has effective and safe to consume for eradication of diseases.


The focus of the discussion is on equity, risk, and defining what is meant by the unexpected in construction. These issues are clearly major elements in the disputes among the several parties dealing with the unexpected in construction. Who bears the cost of the unexpected in construction requires defining who took the voluntary risk with the expectation that he would receive a benefit. The party taking a voluntary risk with the expectation of a reward should pay the cost of the occurrence of the 'unexpected' event. However, the owner is always expected to pay the fair cost of constructing his facility, with the design of his choice, on the site he has selected.

Optimization of the efficiency of antioxidants, AOs, in lipid-based emulsions via chemical modifications of their reactive moieties is not always possible because of the inherent experimental difficulties and because of the regulatory status of AOs. Esterification of hydrophilic AOs may be a practical, convenient, alternative approach. Here we employed a series of caffeic acid derivatives bearing the same reactive moiety but of different hydrophobicity (alkyl chain lengths of 1 to 16 carbon atoms) to investigate the effects of hydrophobicity on the oxidative stability of stripped corn oil-in-water emulsions. AO efficiency was determined by monitoring the production of primary oxidation products (conjugated dienes) with time and a non-linear, parabolic-like, variation of their efficiency with the number of C atoms in their alkyl chain, with a maximum at the C8 derivative, found. To rationalize the results, we also determined the distribution of the AOs between the oil, interfacial and aqueous regions of the same emulsions by employing a recently developed kinetic method that provides the partition constants of the AO between the oil–interfacial, PIO, and water–interfacial, PIW, regions of the intact emulsions. Values of both PIO and PIW range between 180–2000, suggesting that the transfer of the AOs to the interfacial region is spontaneous. The results indicate that the variations of both the percentage of AO in the interfacial region, % AOI, of the emulsions and the AO efficiency with the number of C atoms in the AO alkyl chain parallel each other with a maxima at the C8 derivative. The results illustrate an effective and convenient way to control lipid oxidation by modulation of the hydrophobicity (HLB) of the AOs. An increase in the alkyl chain length of the AOs promote their incorporation into the interfacial region of emulsions but only up to a critical chain length, after which a further increase makes their efficiency decrease as a consequence of the decrease in their % AOI.

Summary form only given. We demonstrate all-optical serial processing for a 100-Gbit/s access node using a novel self-synchronization scheme, which utilizes gain saturation in a semiconductor laser amplifier (SLA) followed by self-phase modulation (SPM) in an optical fiber. The contrast ratio for the header processor is 10:1 and for the demultiplexer is 20:1. Our design avoids the complexity of generating and propagating marker pulses because all pulses in the frame can be identical.


A common need in large scientiic experiments is the ability to monitor by means of simultaneous data acquisition across the whole installation. Data is acquired as a result of triggers which may come either from external sources, or from internal triggering of one of the acquisition nodes. However, a problem arises from the fact that once the trigger is generated, it will not arrive to the receiving nodes simultaneously, due to varying distances and environmental conditions. The Distributed Oscilloscope (DO) concept attempts to address this problem by leveraging the sub-nanosecond synchronisation and deterministic data delivery provided by White Rabbit (WR) and augmenting it with automatic discovery of acquisition nodes and complex trigger event scheduling, in order to provide the illusion of a virtual oscilloscope. This paper presents the current state of the DO, including work done on the Field-Programmable Gate Array (FPGA) and software level to enhance existing acquisition hardware, as well as a new protocol based on existing industrial standards. It also includes test results obtained from a demonstrator used to showcase the DO concept, based on two digitisers separated by a 2.5 km optical ibre.


The conservation of the heritage of native peoples depends on establishing links between different communities and promoting coexistence, well-being and peace among peoples; In this sense, intercultural dialogue is a communication mechanism that seeks to educate individuals who foster more open, plural and dynamic societies where it is possible to build better life opportunities.
In the municipality of Cuetzalan del Progreso, the Masehual have established, within their daily lives, forms of communication based mainly on family and community values, which have been established within their society and which, in some cases, are reproduced in the interaction with the tourists who have come to the municipality for more than four decades.
The tourist interest towards Cuetzalan is due to the fact that it has a wide repertoire of biocultural heritage, preserved by the inhabitants for generations; among which Yolixpa stands out, a medicinal and traditional drink that is currently in a process of transformation in terms of inputs, preparation and meanings, mainly; in which producers, tourism service providers, authorities, tourists and the local population have contributed.
The changes indicated are not homogeneous for all the actors and this is due to the fact that each actor involved has different worldviews and, therefore, different objectives and particular interests, depending on the individual or collective role they represent; In this context of changes and permanence linked to the tourist practice, intercultural dialogue between social actors becomes relevant, for the safeguarding of heritage, including the Yolixpa and its true medicinal and traditional value.
Based on the above, the objective of this study was to assess the relevance and scope of intercultural dialogue, as a management mechanism for Yolixpa, as a biocultural heritage of the Nahua people of Cuetzalan del Progreso, Puebla, for which a qualitative methodological strategy was used. where in-depth interviews, participant observation, intercultural dialogue, focus group, social clotheslines and group dynamics were applied.
It was observed that although the local actors linked to the management of Yolixpa are different, they share common interests around the drink, especially in its permanence and in the recovery of its traditional value; they also recognize that the lack of dialogue has caused disagreements and little participation; The foregoing has been reflected in the management of the Yolixpa festival, in the commercialization, dissemination and promotion of the drink from a mercantilist approach.


Unextracted plasma concentrations of human atrial natriuretic polypeptide (hANP) in 32 normotensive term pregnancies and 18 term pregnancies with pregnancy-induced hypertension (PIH) were measured by kit radioimmunoassay. The mean basal plasma hANP concentration was 299 ± 46 (X ± SD) pg/ml in uncomplicated term pregnancies and 378 ± 75 pg/ml in women with PIH (p < 0.001). Furthermore, two subsets of patients with PIH could be identified on the basis of hANP alone and not on clinical parameters. In one subset, seven PIH patients exhibited hANP concentrations within the 95% confidence limits of uncomplicated pregnancy hANP concentrations, while another subset of 11 hypertensive patients demonstrated markedly elevated hANP (436 ± 53 pg/ml). Maternal age, parity, fetal weight, and gestational age did not affect hANP concentrations in normal term pregnancies. These results suggest that: 1) hANP concentrations do not change during normal pregnancy; 2) are significantly elevated in patients with PIH at term; 3) ...


The role of high serum cholesterol levels in the clinical outcome of kidney-transplanted patients has been described in a recent report by Roodnat et al. (1). Their study of 676 kidney graft recipients showed that serum cholesterol levels have an independent influence on the graft, patient, and over-all graft failure. Because hyperlipidemia occurs in 60 – 80% of kidney transplant recipients (2), their findings might be of clinical value for the future improvement of kidney transplantation outcome. Although the underlying mechanisms of their findings are not clear, high serum cholesterol levels may increase the risks of cardiovascular disease and impair renal function, which may influence graft and patient survivals. In this letter, we will highlight another aspect of the role of high serum cholesterol levels on graft outcome in kidney transplanted patients. Serum cholesterol levels are reported to have an influence on cyclosporine blood disposition (3). In blood, about 40% of cyclosporine are bound to erythrocytes and 50 – 60% to cholesteroland triglyceride-containing lipoproteins (4). Cyclosporine is suggested to be incorporated into peripheral blood lymphocytes (PBLs) through low density lipoprotein(LDL) receptors on the cell surface such as the LDL-cyclosporine complex (5). High blood levels of LDL possibly increase the amount of LDL-bounded cyclosporine, but this may in turn down-regulate LDL-receptors on the cell surface (6), and subsequently reduce cellular uptake of LDL-cyclosporine complex. Indeed, hypercholesterolemia is reported to inhibit cyclosporine efficacy in nephrotic syndrome (7). In our retrospective pilot study in patients with nephrosis, we found that both total serum cholesterol and LDL-cholesterol levels are significantly correlated with individual IC50 values of cyclosporine against PBL blastogenesis in these patients (r50.733; P,0.002; n516 and r50.830; P,0.03; n57, respectively; unpublished results). A high serum cholesterol level is one of the typical clinical symptoms of nephrotic syndrome. Thus, these observations suggest that high serum cholesterol levels attenuate suppressive efficacy of cyclosporine against blastogenesis of patients' PBLs in nephrosis. Of 676 recipients in the study of Roodnat et al.(1), 456 were treated with cyclosporine, and therefore serum cholesterol levels may possibly have had an influence on pharmacokinetics and/or pharmacodynamics of cyclosporine in these 456 recipients. One possible explanation for the increased incidence of graft failure in the recipients with high serum cholesterol levels is cyclosporine efficacy attenuation through an intervention of cyclosporine uptake into T lymphocytes via LDL-receptor down-regulation. From these points of view, a comparative evaluation of the effects of serum cholesterol levels on clinical outcome, especially incidences of rejection episodes and graft failure, between recipients treated with azathioprine and those treated with cyclosporine could be both interesting and informative in the study of Roodnat et al. (1). In addition, careful monitoring of immunological status and signs of rejection due to attenuation of cyclosporine immunosuppressive efficacy appears to be important to the recipients treated with cyclosporine when their serum cholesterol levels are unusually high.


The antitumour elAect of the combination of razoxane and radiation has been compared with a number of cytotoxic drugs combined with a similar dose of radiation. The drugs were compared at maximum tolerated and minimum effective doses. Most experiments were done with sarcoma 180 mouse tumour, but in some the B16 and in others the Lewis lung carcinoma (3:LL) was used. Fractionated razoxane hut well below maximum tolerated dose and radiation were the most effective combination for sarcoma 180. The combination was more than additive in its tumour inhibitory effect on the B16 melanoma and also in its effect on the secondary tumours from 3LL. Possible mechanisms of action are discussed.

A transport device includes a medium carrying unit on which a medium having a first surface and a second surface opposite the first surface is superposedly wound in a cylindrical shape so as to form a roll body, the second surface being oriented so as to form an inner circumferential surface in the roll body, a route defining portion fixed in a curved shape so as to guide the medium such that the second surface is oriented to the inner side of the curve, and a slave roller that nips the medium in collaboration with a transport roller so as to deform the medium such that the second surface becomes oriented to the outer side of the curve, the slave roller being located downstream of the route defining portion in the transport direction of the medium.


The physical properties of five siloxane polymers with different types and frequencies of amino functional groups along the polymer side chains have been manipulated from flowing liquids to gels and to rubber-like materials by the simple addition or subtraction of a neutral triatomic molecule, CO 2 or CS 2 , at room temperature. The chemical changes, formation of ammonium carbamates and ammonium dithiocarbamates, create materials whose properties are totally different from those of the parent polymers as a result of the introduction of ionic cross-links. These materials can be returned to their original forms by heating (in the case of the CO 2 adducts) or to their protonated original forms by treatment with an acid (in the case of the CO 2 and CS 2 adducts). Heating the ammonium dithiocarbamates leads to loss of H 2 S and permanent (covalent) thiourea cross-links between the polymer chains. The new materials adhere strongly to other surfaces and can be swelled to several times their original volumes by different liquids. The rheological, swelling, and physical properties of the new materials have been correlated with the structures of the original polymers to provide a comprehensive picture of how changes at the nanometric length scale are translated to macroscopic changes. At least for the polysiloxanes examined here, the properties of the adducts do not correlate with the molecular weights of the original polymers, but do with the frequency of amino groups. The results demonstrate a simple, new method to cross-link polysiloxanes (and, in principle, a wide range of other polymers), transforming them into materials with totally different and potentially commercially useful properties.


IN PERFECT CAPITAL MARKETS, financial intermediaries lack a raison d"etre. Traditionally, intermediaries have been portrayed solely as issuers of indirect debt who develop and exploit a wedge between equilibrium borrowing and lending rates.' But this explanation ignores the fact that nonmutual depository institutions intermediate for their shareholders, too. This paper seeks to explain how a firm can perform a useful function by holding a portfolio of efficiently priced securities that its stockholders could in principle have purchased directly.2 Clearly, the answer has to lie in models that allow a financial firm to build or maintain security portfolios for its shareholders more cheaply than its shareholders could on their own. This insight leads us in Section II to a theory of financial intermediaries that features diversification costs and (via information risk) imperfect substitution between homemade diversification and diversification produced by firms. With differential diversification costs and benefits, it is rational for a firm to engage in a prior round of asset diversification on behalf of its shareholders even when all assets are priced efficiently and available for direct purchase by shareholders. Within this framework, the financial firm intermediates just as truly when it issues common stock as when it issues indirect debt. From the point of view of stockholders, financial institutions are specialized producers of diversification services. Although comparative advantages in diversification might be used (along with limited liability) to explain the emergence of firms in general, firm-produced diversification services must be especially attractive to the subset of stockholders that invests in diversification specialists. The clientele theory of stock prices imparts new perspective on the operations of a value-maximizing financial institution.


The brown tree snake (Boiga irregularis) is an opisthoglyphous colubrid snake indigenous to northern Australia, New Guinea, and the Solomon Islands. Its paired Duvernoy's gland, located lateral to the maxilla and overlapped along its ventral edge by the supralabial gland, is a branched tubular and compound exocrine gland made up of a vertical stack of mostly longitudinal lobules. Ducts within each lobule converge, forming common lobular ducts that empty into a central cistern, a central collecting area of the duct system within the hilus of the gland. From the central cistern, a single main duct carries secretion to enlarged posterior maxillary teeth. Storage area for the secretory product is limited. Histochemical tests of the secretory cells were negative for all lipid and carbohydrate stains (including periodic acid-Schiff) and positive for proteins, suggesting a glandular product that is primarily proteinaceous with few lipid or carbohydrate components. Histochemical tests of the duct epithelium indicate the production of mucins and nonsulfated mucopolysaccharides. The Duvernoy's gland of B. irregularis is histologically and anatomically distinct from a true venom gland.

In order to obtain the fundamental data in ferronickel and cupro-nickel smelting, equilibrium experiments between magnesia saturated FeOx-SiOz-MgO slags and liquid Cu-Ni-Fe alloys were carried out under controlled oxygen potential at 1673 and 1773K. The MgO solub1lrty in the FeOx-Si02 slag increases from 16 to 32 mass% with increasing Si02 content at 1773K. The Ni and Cu contents in the slag decrease with reducing oxygen potential or increasing temperature. By comparing the values of the distribution ratio, Lrm, Fe will remain basically in the slag while Ni and Cu will concentrate in the alloy phase. At 1673K, the Ni dissolution will be lower than Cu at Po2 = 3x1Q-4 Pa. Based on the logarithmic relationship between the distribution ratio and the oxygen potential, the predominant species dissolved in the sla& are NiO, CuOo.5, FeO, CoO and Sb01.5. Usmg the act1V1ty values of Ni and Cu determined by a Knudsen cell mass spectrometer, the activity coefficients of NiO and CuOo.s in the slag were estimated to be approximately 3.5 and 4 to 7, respectively. The high content of MgO does not significantly affect the dissolution of these metals in slag.


The study aimed to compare the effects of elastic and weight resistance exercise on muscular activation patterns. Twenty‐one moderately active males (age = 25 ± 8) performed ten bicep curls and leg extensions with weights (W), an equivalent elastic resistance (T), and a combined condition (TW) of half elastic tension and half weight resistance. Muscular activations of the biceps, triceps, rectus femoris, vastus medialis, and lateralis were recorded with Trigno wireless electrodes, and joint angles were recorded with Qualisys Track Manager. Biceps total activation was highest (P < .001) with weights during the bicep curl due to an increased (P ≤ .007) activation in the eccentric phase. The biceps was also active over a larger portion of the ROM under TW (110°‐70° elbow angle), while W and T exhibited peak activations at mid (90°)‐ and late (50°) stages of ROM, respectively. The triceps (bicep curl) was least active (P < .05) with W throughout the concentric phase, as were the vastus medialis and lateralis (leg extension). Although peak and total activation were similar for most muscles in all conditions, muscular activation patterns differed between conditions indicating that TW may enhance strength gains by increasing time under tension, engaging agonist muscles at less advantageous lengths, and increasing the recruitment of auxiliary muscles.

This paper describes ImAtHome, an iOS application for smart home configuration and management. This application has been built over the framework HomeKit, made available in iOS, for communicating with and controlling home automation accessories. Attention has been put on the design of the interaction with such an application, in order to make the interaction style as much coherent as possible with iOS apps and supporting users without programming skills to unwittingly create event-conditionaction rules that, in other similar systems, are usually defined through "if-then" constructs. The results of a user test demonstrate that ImAtHome is easy to use and well accepted by end users of different age and background. Smart home; end-user develoment; rule-based programming


Vapor-permeable building envelopes have received renewed interest because they can moderate indoor humidity levels and improve the drying of the envelope during summer condensation conditions. In this paper, the moisture performance of a vapor-permeable building envelope is presented with field measurements and numerical simulations. The results show that the diffusion resistance of the internal surface should be greater than that of the external surface (typically recommended ratio of 3: 1 or 5: 1), but that the vapor resistance of the vapor retarder can be significantly below that provided by polyethylene and still result in a safe structure, even in a cold climate.

Lanthanide‐tris(fod) reagents interact reversibly in solution with Ag(fod) to form binuclear adducts having the formula AgLn(fod)4. The formation constant (K) for AgYb(fod)4 in CDCl3 is 500 M−1, and this equilibrium is in the slow exchange region below 20°C. Slow exchange is also found for AgDy(fod)4. The NMR data support a structure for the binuclear adduct consisting of an ion pair with a silver cation and a lanthanide‐tetrakis(fod) anion. The binuclear reagent associates weakly with benzene (K = 3M−1). The primary interaction involves coordination of the silver cation to the aromatic ring, and the tetrakis(fod) anion is situated in close proximity to the silver cation. Induced shifts for the aromatic moiety are primarily pseudo‐contact in origin.


Accurate parameter estimation of small scale DC motors is a challenging and a complex task compared to it's large scale counterpart. This research proposes a novel technique of parameter estimation based on the disturbance observer and optimization algorithms for DC motor applications. A simplified yet an accurate cost function has been proposed for the model which is based on the disturbance observer (DoB). Newton Raphson algorithm is used as the optimization algorithm. Moment of inertia, static friction, and coefficient of viscous friction are estimated and compared with the actual parameters. Simulations were carried out to justify the approach. The novel parameter estimation technique has shown accurate results compared to the existing methods.


Simple Summary Despite progress in the biology and upfront treatment of childhood medulloblastoma, relapse is almost universally fatal. No standardized treatment has so far been established for these patients. By determining which characteristics are prognostic after relapse, treatment strategies may be optimized for each of these children. We demonstrated that molecular subgroup at diagnosis is a relevant prognostic factor of outcome after relapse. Moreover, we showed that time to relapse and the use of salvage radiotherapy at relapse might have a potential impact on post-relapse survival. Our data suggest that ongoing efforts toward a better understanding of the biology, timing and type of relapse would be important to understand the determinants of tumor behavior at relapse. This could help us address more specific questions on the best surveillance strategies after completion of the treatment and the introduction of risk-stratified second-line treatment strategies. Abstract Given the very poor prognosis for children with recurrent medulloblastoma, we aimed to identify prognostic factors for survival post-relapse in children with childhood medulloblastoma. We retrospectively collected clinico-biological data at diagnosis and main clinical characteristics at relapse of children newly diagnosed with a medulloblastoma between 2007 and 2017 at Gustave Roussy and Necker Hospital. At a median follow-up of 6.6 years (range, 0.4–12.3 years), relapse occurred in 48 out 155 patients (31%). The median time from diagnosis to relapse was 14.3 months (range, 1.2–87.2 months). Relapse was local in 9, metastatic in 22 and combined (local and metastatic) in 17 patients. Second-line treatment consisted of chemotherapy in 31 cases, radiotherapy in 9, SHH-inhibitor in four and no treatment in the remaining four. The 1-year overall survival rate post-relapse was 44.8% (CI 95%, 31.5% to 59.0%). While molecular subgrouping at diagnosis was significantly associated with survival post-relapse, the use of radiotherapy at relapse and time to first relapse (>12 months) might also have a potential impact on post-relapse survival.


In this paper,the measurement of GIS Exploratory Spatial Data Analysis had been researched in the land price distribution information abstraction.Because two premises in the traditional statistical couldn't be achieved land price samples,others method should be searched in this research.Exploratory Spatial Data Analysis(ESDA)have been set up in maths basic,and it have some spatial method in land price distribution research,and few sample should be need and the spatial relevance had been considered,So it can be used the research of land price distribution.The actuality research of ESDA had been expounded in a case of city commercial land price by GIS Arc/Info 8.0 in this paper.Firstly,its mathematics basic had been introduced.And then,the man's measurements of GIS Exploratory spatial Data Analysis had been researched,it included the data structure research,full trend analysis,searching direction and so on.In the last,the GIS Exploratory Spatial Data Analysis measurement had been introduced by taking Kriging Analysis as an example.The error analysis indicated that if the frequency distributing of the sample presented as Normal Q-Q Plots and the measurements had been used in reason,the result could be accepted.On the contrary,the data should be transformed.Only in this,the result of GIS Exploratory Spatial Data Analysis is reliable.


A genetic analysis of population structure in the unisexual fish, Poeciliopsis monacha-lucida, was conducted using protein phenotypes encoded by 22 loci. The all-female populations arose by hybridization between P. monacha and P. lucida in narrow zones where their ranges overlap. The unisexual hybrids are sustained by mating with males of P. lucida and are phenotypically intermediate, expressing both maternal and paternal traits. However, only the maternal (P. monacha) set of chromosomes is transmitted through oogenesis in these hybrids; recombination does not occur. By mating laboratory strains of P. monacha-lucida, derived independently from 37 wild females, with males of P. lucida of known genotype, the haploid genotype (haplotype) of the clonally inherited monacha genome was determined. Eight distinct haplotypes were identified among the clonally inherited genomes of the 37 strains. This variation indicates that a minimum of eight clonally inherited genomes (hemiclones) occur naturally, although each of these eight haplotypes may include additional variation at other loci that we failed to observe. Two of the eight haplotypes were found at three distant localities in the Rio Fuerte and may represent well-adapted, generalized clones that have spread to inhabit both stable and diverse habitats as well as fluctuating and depauperate habitats in this river. Additional, unique haplotypes were found only at localities where hybrid syntheses could occur. These haplotypes may represent newly arisen hemiclones that have not yet dispersed. When compared with sexual species, the unisexual fish maintain significantly higher levels of heterozygosity ranging from a low of 36.3% to a high of 50.0% of the tested gene loci in an individual. The high levels of heterozygosity, attributable to their hybrid origin, along with their reproductive potential and vigor apparently explain the success of these unisexual forms.


This report describes the testing and construction details of nine test sections with varying textural characteristics. The impacts of various surface textures (sawed vs. tined, longitudinal vs. transverse, and random vs. uniform spacing) on the frictional and noise characteristics of pavement surface were examined. Skid numbers were acquired according to ASTM E 274 procedure with ribbed- and smooth-tire (ASTM E 501 and 524) at 40, 50, and 65 mph (64 km/h, 80 km/h and 105 km/h) for all the test sections. Six different types of texture measuring devices were used to measure and compare the amount of texture in each of the test sections. To examine the noise properties of the test sections, noise data were acquired in three different locations: inside the test vehicle, 25 ft (7.62 m) from the center line, and near the right rear tire of the test vehicle away from the exhaust pipe. The smooth-tire showed more sensitivity to both micro- and macrotexture than the ribbed-tire. Longitudinal textures are more quiet than transverse textures.


CLYTEMNESTRA'S.DREAM OF GIVING BIRTH TO A SERPENT and her bare-breasted confrontation with her son have long been at the center of various literary and psycho-analytical interpretations of Aeschylus' Oresteia.' It is generally accepted that Clytemnestra's bare-breasted supplication of Orestes alludes to Hecuba's similar supplication of Hector in the Iliad.2 The abundance of snake imagery applied to Clytemnestra and Orestes in the Choephori has usually been attributed to the influence of Stesichorus, whose Oresteia contains a striking serpent image of its own.3 In this paper, I will re-examine the relationship of Clytemnestra's supplication to the Homeric model, and argue that significant material found in the same context in both works has been passed over by modern scholarship. Building on the allusion to Hecuba's supplication, I will argue that the Aeschylean image of the serpent at the breast has an antecedent in this Homeric passage, creating an important intertextual relationship. Finally, I will show how this intertextual relationship illuminates the inter-personal dynamics of the climactic scenes of the Choephori. Reading has been described as an act of comparison, seeking a text's resemblance to, and difference from, other texts.4 The term intertextuality describes how a text depends on other texts for meaning, and describes the discursive space that a text occupies in relation to other texts. The expansiveness of intertextuality makes it almost impossible to discuss with regard to specific texts without violating the terms of its definition.s It is all-embracing in that a text is read in relation to all other texts. Yet, as soon as a reader compares a text with a single other text, the expansiveness of intertextuality is called into

the amount of mutual gaze between the pair was recorded, along with the task performance measures. In order to manipulate purported agency, prior to the interaction users were either told that the agent they were interacting with was human-controlled (an avatar) or computercontrolled (an agent). Social presence measures were taken, in the form of questionnaires administered during the interaction. The relationship between the amount of mutual gaze, purported agency of the interlocutor and reported social presence was investigated, and the implications for mutual gaze and its relationship to social and task-related measures were discussed.


People in Bangladeshi village area have long practice to take plant-based products for their basic health care. Schleichera oleosa (Lour.) Oken (Family: Sapindaceae) is an important folk medicine in Bangladesh, India that has been used to cure a wide variety of human ailments. Here, the crude methanol extract of S. oleosa leaf (MESOL) and its various solvent (Hexane, dichloromethane, ethyl acetate, aqueous) fractions were evaluated to determine the level of biological activities by both In vitro and in vivo approaches. The crude methanol extract along with its different solvent fractions was investigated for antioxidant activity by measuring total phenolic content and DPPH radical scavenging assay. Cytotoxic activity was performed by brine shrimp lethality bioassay method. The blood clot lysis ability was screened using aspirin as standard. In vitro anti-inflammatory test was performed by RBC membrane stabilizing activity. Beside In vitro analysis, tail immersion procedure and formalin-induced writhing test were carried out to evaluate the analgesic activity of the plant extract in mice. In addition, the anti-diarrheal activity was determined by castor oil-induced diarrheal model in mice. The ethyl acetate fraction of S. oleosa showed prominent antioxidant activity by scavenging DPPH radical with an IC50 value of 9.46 μg/ml, possibly due to its highest phenol content (103.23 mg of GAE/g of plant extract). The crude methanol extract revealed significant cytotoxicity towards brine shrimp with an LC50 value of 16.79 μg/ml. The dichloromethane fraction showed moderate blood clot lysis ability (28.93% clot lysis) while the crude methanol extract of S. oleosa leaf produced the highest 74.62% inhibition of hemolysis that was induced by hypotonic solution. During in vivo assay, the crude methanol extract of S. oleosa leaf produced significant (p<0.05) and dose-dependent pain response and anti-diarrheal effect in mice. The present study revealed that Schleichera oleosa possesses significant pharmacological activities. However, additional studies are compulsory to discover the mechanism of action of this plant extract.


In the paper, development on MBE-based SiGe/Si heterojunction bipolar transistors (HBT) is described. The SiGe/Si film used in the present work was grown by SIVA32 molecular beam epitaxy system made in Riber, France. 3 micrometers process technology with poly-silicon emitter was used to develop SiGe HBT devices. The experimental results indicated that both the direct current characteristics and the cutoff frequency of SiGe HBT are satisfactory. The current gain (beta) of HBT devices is 50, when the collector voltage Vc equals 2V and the collector current Ic equals 5 mA. The cutoff frequency fT equals 5.1 GHz. And the uniformity of the cutoff frequency of HBT is quite good.


Undifferentiated carcinomas with osteoclast‐like giant cells are rare pancreatic and periampulary neoplasms that morphologically mimic giant cell tumor of bone. Despite numerous publications based primarily on single case reports, the terminology, histogenesis, and biologic behavior of these tumors remain controversial.


The researches until now showed that improvement of maximal running speed is possible only by applying the simulatory process in specific speed and coordination conditions aimed at development of speed-powerful abilities. Pursuant to the prior statement the subject of this research is improvement of maximal running speed influenced by the two chosen methods - rapid excitations and force generation. Simulated stimulus should have contributed the increase of one of the basic factors of maximal running speed - step frequency, insofar as time duration of the phase contact with surface will decrease. On the sample of 19 students of the Faculty of Sports and Physical Education of the University of Belgrade, upon the application of the experimental stimulus, the changes of kinematic and dynamic features while running at maximal speed at the section of 20 m with 'flying' start were analyzed. The research results proved that a statistically significant (p<0,05) improvement of maximal running speed occurred with both groups of examinees, which was the general aim of the research.

The Sao Paulo marsh antwren (Formicivora paludicola) is a critically endangered bird endemic to marshes in the metropolitan region of Sao Paulo city, Brazil. The total population is estimated to be around 300 individuals, distributed among 15 small (\50 ha) frag- ments, suggesting that loss of genetic variability may affect the long-term viability of this species. To develop genetic tools for gaining information on effective population sizes, inbreeding and gene flow between populations, we describe nine polymorphic microsatellite loci isolated from a F. paludicola library using next-generation sequencing. We report on levels of variation in these novel microsatellites and eight additional heterologous loci in these birds. Expected (HE) and observed (HO) heterozygosities aver- aged 0.72 and 0.70, respectively, and the number of alleles per locus ranged from 3 to 10. These loci will permit evaluation of whether artificial translocations are necessary for long-term viability of this rare bird.


In the current study, the narratives of bilingual middle school 7th grade students who acquired Turkish as a second language were examined in terms of the elements of coherence and cohesion, which are among the criteria of textuality. The study group of the current research is comprised of 20 bilingual 7th grade students attending a middle school in the Mazıdağı district of the city of Mardin in the spring term of the 2020-2021 school year. All the students in the study group are bilingual students who first acquired Kurdish and then Turkish at school or in the social environment. The study is descriptive in nature and was carried out using the survey method. In addition, a document analysis was performed on the narrative writings obtained from the students in the study. The data obtained from the study were analyzed with the measurement tools of the "Coherence Level Evaluation Chart" and the "Cohesion Level Rubric". In the study, the bilingual 7th grade students were asked to create another story based on a minimal story that was given to them before and combining this short story with the new story they were going to create. The students were asked to put the minimal story given to them in any part of the story according to the plot of the new story they would create. In this way, the effect of bilingualism on the students' writing coherent and cohesive texts was investigated on the basis of the narrative texts the students had written. In the study, it was determined that the students' mother tongue was also reflected in their narrative writings and they formed their texts in line with the language schemes they first acquired.


Brass is widely used as turbine material for cooling system for marine propellers. However, it is vulnerable to corrosion by contact of air or aqueous chloride solution. The essential oil of Myrtus communis (MO) was tested as a brass corrosion inhibitor (Cu70-Zn30) immersed in the 3% NaCl solution, using a polarization technique and electrochemical impedance spectroscopy. The effect of MO concentration, temperature and immersion time was studied to evaluate the action of the inhibitor. The results showed that the protection efficiency was enhanced with the increasing of MO concentration, and the potentiodynamic polarization experiment showed that MO acts essentially as a cathodic inhibitor. In addition, experiments have shown that MO inhibition efficiency decreases with increasing immersion time and temperature. The film adsorbed on the brass surface containing MO was confirmed by the results of the Scanning Electron Microscope (SEM) and the Energy Dispersive X-ray (EDX). The overall results affirmed the potential use of MO as inhibitor agent of brass corrosion in the 3% NaCl solution.

Previous analytical investigationsIJ have identified aluminium, such as aluminosilicate deposits, in both intraneuronal neurofibrillary tangles and senile plaques (SP) in the brains of subjects with Alzheimer's disease (AD), the leading cause of senile dementia. Association of high concentrations of aluminium with the two major neuropathological features of this disorder suggests that this metal may be involved in the aethiopathology of AD. Aluminosilicate minerals, such as clays and zeolites, are ubiquitous in the environment and can catalyze a variety of chemical reaction^."^ Several in vitro and epidemiological studies have respectively demonstrated the neurotoxicity of aluminiums and a positive correlation between aluminium content of natural drinking water and the incidence of AD.h Moreover, recent clinical studies indicated a decrease in the rate of disease progression following the administration of desferroxamine, an aluminium chelator, to clinically diagnosed sufferers of AD.' Candy et al. I have shown that aluminium was present at the center of SP cores, which contrasts with the distribution of other inorganic constituents. Aluminium is thus likely involved in the initiation or early stage of SP formation.' However, in spite of these in vitro and in vivo evidences, the possible role of aluminium in the neurodegenerative process of AD still remains unknown. A responsibility of aluminium in brain oxidative stress has been hypothesized by Evans et aLx who demonstrated the capacity of various model aluminosilicate particules to stimulate the in vitro production of microglial-derived reactive oxygen metabolites (ROM), such as superoxide anion, hydroxyl radical, and hydrogen peroxide. Their results provided evidence relevant to the potential cellular mechanism by which the aluminosilicate deposits in the core of SP may act in the aethiopathogenesis of AD. Evidence for the pathogenic role of microglial macrophages in this disorder received some support with the demonstration of activated microglia associated with early senile plaque f~rmat ion .~ Moreover, several data suggest that microglial cells could represent a major source of nitric oxide (NO) within the central nervous system.lo,ll To our knowledge, a possible link between aluminium, microglial cells, NO, and AD has not been investigated so far. The aim of our study is to examine


The growth of thin Ni film on Ni(100) has simulated by a three-dimensional kinetic lattice Monte Carlo simulation. With the logical model of the atom deposition,atom diffusion and atom growth,etc,the surface feature and surface roughness of Ni thin films have been studied. The results indicate that:many near square compact islands are formed gradually from the dispersive atoms on the surface at the early stage.With increasing deposition time,the film changed from the two-demensions to three-demensions.The higher the substrate temperature is and the lower the deposition rate is,the lower the surface roughness is.As the deposition rate remains unchanged,the surface roughness decreases with increasing substrate temperature. Moreover,the surface roughness becomes zero when the substrate temperature goes up to some value.

Physical and electrical properties of chemically-vapordeposited polycrystalline silicon films have been investigated. Effects of deposition parameters, doping, and high temperature processing on grain size and orientation, carrier concentration, carrier mobility and electrical resistivity, have been studied. By relating the physical and electrical properties to each other it has been shown that electrical conduction is controlled by dopant segregation, carrier tunneling, and trapping at grain boundaries. Models for these three mechanisms have been developed and by combining them a generalized model for electrical conduction has been developed. Presence of grain boundaries has also been shown to strongly influence the thermal oxidation and dopant diffusion in polycrystalline silicon.


VPN is a communication technology that allows a user to connect to a public network, and use it to join a local network. By using this public network, users can be incorporated into a local network, obtaining the same rights and settings as when a user is on a LAN network. So that user can communicate with the local LAN network at a corporate agency. VPN can occur between two end-systems or two PCs or it can be between two or more different networks. VPNs can be established using tunneling and encryption technologies. VPN connections can also occur on all layers of the OSI protocol, so it can create VPN communications. Thus, VPN can also be categorized as an alternative WAN infrastructure to gain a personal point-to-point connection between offices and destinations. And this is done by using any media, without the need for leased line media or frame relay.

Representation and Prediction Features Initial experiments showed that replacing prepositions by simple place-holders decreases the translation quality. As an extension to the basic approach with plain place-holders, we thus experiment with enriching the place-holders such that they contain more relevant information and represent the content of a preposition while still being in an abstract form. For example, the representation can be enriched by annotating the place-holder with the grammatical case of the preposition it represents: for overt prepositions, case is often an indicator of the content (e.g. direction/location), whereas for NPs, case indicates


The methodology applied in previous MDs has shown the possibility of using BTFs measurements to estimate the transverse Landau Damping of the beams for different machine configurations. However, measurements with beam-beam interactions could not be performed during the past MDs. This note summarises the procedure and preliminary results of the MD 3292, carried out in two different MD Blocks (Block 3 and 4), during which BTF measurements in the presence of white noise and beam-beam interactions were acquired.


A transparent NaBa4Al2B8O18Cl3 (NBAC) crystal with dimensions of 38 × 36 × 10 mm3 was successfully grown by the top-seeded solution growth method using a new flux NaF–NaCl. The crystallization region of NBAC is revealed in a quasi-ternary system of NBAC–NaF–NaCl. By means of eliminating the extrinsic UV absorption of Fe3+ impurity, the UV absorption edge was redetermined to be 183 nm rather than the previously reported 230 nm. The nonlinear optical (NLO) coefficients of NBAC were measured by the Maker fringe technique, which gave results of d15 = 1.27d36(KDP) = 0.49 pm V−1; d33 = 2.25d36(KDP) = 0.88 pm V−1. Calculations on the local dipole moment reveal that the NLO effect of NBAC is attributable to ClNaBa4 polyhedra, BO3 triangles, and ClBa4 tetrahedra. In addition, the ac dielectric and conductivity were measured using complex I–V method.


Objective To explore the method and effect of single utility port video-assisted thoracoscopic surgery(VATS) for the treatment of pulmonary diseases.Methods From Jan.2008 to Jun.2010,158 patients with pulmonary diseases were treated by single working pore VATS in the Department of Thoracic Surgery of West China Hospital, Sichuan University.Their diseases included 6 kinds of different lesions,such as pneumothorax(inflammatory pseudotumor,hamartoma,lymphangiomyomatosis),lung tuberculoma,and lung carcinoma.Seventy patients had definite diagnosis before their operation,and the others had their final diagnosis by intraoperative frozen section evaluation and postoperative pathology examination.All the resections were carried out by pure thoracoscopic procedures with two ports,one working pore and one observing pore.A 28-Fr chest tube was placed to the pleural apex.Limited lung resection was performed in 151 patients,single lobectomy in 7 patients,and simultaneous bilateral operation in 6 patients.Results For limited lung resection patients,the average operation time was 18(5-60) min,and the average blood loss was 33(5-95) ml. No patient needed intraoperative blood transfusion.Ten patients received an increased pore,including 6 patients with pleural cavity obliteration or abundant pleural adhesions,and 4 patients with intraoperative bleeding.The average postoperative length of stay was 2.5(2-4) days,and the average medical cost was 17 884(15 476-25 387) Yuan.For patients undergoing lobectomy and lymph node dissection,the average operation time was 128(50-220) min,and the average blood loss was 180(80-478) ml.No patient needed intraoperative blood transfusion.One patient received an increased pore.The average postoperative length of stay was 4.7(4-7) days,and the average medical cost was 42 385(38 965-57 695) Yuan.No perioperative death or severe complications were observed in present series.Conclusion Single utility port VATS is a safe and efficient procedure with good patient recovery.It is a method of choice for selected patients with pulmonary diseases.


Alongside the substantial transformation of the concept of architectural heritage, the models, strategies and tools that promote their protection, have also been subject to significant changes over time. Simultaneously, and also in an inevitable way, the settings has been taking a progressive and predominant role in the protection and the criteria that mediate the interventions in the architectural heritage. The most recent heritage charters and recommendations refer to the importance of settings - extended to the concept of "place" - to the meaning of cultural heritage and therefore the need to develop tools to promote their conservation and management. This article presents a research proposal that aims to reflect on this theme: the setting of architectural heritage. The ultimate goal of this project is to provide a critical platform, to contribute actively to the need for reflection on the Special Protection Zones of classified heritage, particularly on its boundaries. This purpose will be based on developing three main research lines: the interpretation of the territorial relations of the built heritage, the identification and characterization of special protection zones that exist in Portugal and the comparative study of different European experiences in the protection of settings of cultural heritage.


Abstract There is broad agreement that the most important transformation undergone by democratic politics since the second half of the twentieth century has been the diffusion of the means of mass-communication (television in particular). Teledemocracy especially has changed democratic politics in a specific way: the leaders rather than the parties now stand at the centre of the electoral and political process. This article does not aim to go over the relationship between media and politics; that has already been done. Instead, it focuses on how to deal with a situation in which media and politics overlap.


CMSY method was used to calculate Biological Reference Points (BRPs) of Harpadon nehereus using seventeen years (2001-2017) of catch data from the Bay of Bengal (BOB), Bangladesh. CMSY requires only catch and resilience data with quantitative stock status information. Also, a Bayesian statespace implementation of the Schaefer production Model (BSM) was used. The lowest Maximum Sustainable Yield (MSY) was provided by BSM (60600 t) that was smaller than last year's catch (82767 t in 2017). The fishing mortality (F) was estimated to be 0.22 and 0.23 for CMSY and BSM, respectively. The intrinsic population growth rate (r) was lower according to BSM (0.37) than the CMSY (0.57). Calculated B/BMSY was 1.13 and F/FMSY was 1.21 from the BSM model for the last data year. Estimated BRPs directed the overfishing status that may lead the H. nehereus fishery to be unsustainable. Therefore, proper management strategies are required to ensure the sustainability of H. nehereus in the BOB, Bangladesh.

This paper describes the method of direction of arrival(DOA) estimation for many groups of coherent and uncorrelated sources under mutual couple based on Toeplitz matrix.The method first estimates the mutual couple parameter of the linear array,and compensates the array date using the mutual couple parameter.Then,the method decoherences the coherent sources by using Toeplitz matrix.Finally,the DOA of each source is estimated by using the MUSIC method.Experimental results show that the algorithm is effective in solving the influence of mutual coupling,avoiding the loss of array,and realizing the accurate estimation of small sources.


A new fully self-consistent nonisothermal, two-di- mensional model of a semiconductor laser device is presented. The model consists of the simultaneous solution of the electrical equations (Poisson's and electron and hole continuity equa- tions), along with the wave equation, photon rate equation, and thermal conduction equation. An analysis is presented for an AIGaAs-GaAs ridge laser diode structure using this model as a representative example. The results agree well with available experimental data. A comparison of the results between iso- thermal and nonisothermal simulations shows that the noniso- thermal case has a higher threshold current and lower quan- tum efficiency than the idealized isothermal model as expected. The result was found to depend critically on the thermal ex- change boundary condition of the simulated device, demon- strating the importance of considering thermal exchange in the design of laser diodes.


Molecular design breeding is a highly integrated system built on multiple scientific disciplines and technological areas. It allows the simulation and optimization of the breeding procedure before breeders' field experiments. Thus the best target genotypes to meet various breeding objectives in various ecological regions, and the most efficient and effective crossing and selection strategies approaching the best target genotypes can be identified. The design breeding greatly increases the predictability in conventional breeding, leading to the evolution from "phenotypic breeding by experience" to "genotypic breeding by prediction" and an increased breeding efficiency and effectiveness. Three major steps are involved in design breeding. The first step is to identify genes affecting breeding traits and to study gene and gene interactions, i.e., to seek for the original materials for producing the crop cultivars, which includes establishment of genetic populations, screening of polymorphism markers, construction of linkage maps, phenotypic evaluation and genetic analysis etc. The second step is to determine the target genotypes for various breeding objectives in various ecological regions, i.e., prototype of the final cultivar product, which includes the genotype-to-phenotype prediction based on identified and known gene information, i.e., locations of genes on chromosomes, biochemical pathways and expression networks from genes to traits, their genetic effects on breeding traits, and the interactions between genes. The third step is to identify the most efficient breeding strategies leading to the target genotypes determined in the second step, i.e., a detailed blue chart to produce the designed crop cultivars. Significant progresses have been made in crop molecular design breeding in China in recent years. This paper first summarized major progresses made in the development of novel genetic materials, genetic

The sensitivity and selectivity to H2 of a new In203-based gas sensor were improved significantly by surface chemical modification. A dense layer of SiO2 near the surface of the porous In2O3 bead was formed by chemical vapor deposition (CVD) of diethoxydimethysilane (DEMS). The dense layer functioned as a molecular sieve, thereby the diffusion of gases with large molecular diameters, except for 1-12, was effectively controlled, resulting in a prominent selectivity and high sensitivity for H2. The working mechanism of the sensor was also presented.


Free oil, rather than adsorbed oil, is potentially the most producible component of tight nanoporous shale reservoirs using existing technologies. To date, a variety of geochemical parameters, mainly related to the retention, migration, and expulsion of generated oil, have been developed to estimate the free oil in shale. However, there is still a lack of theoretical models accounting for the mechanism of oil accumulation in nanoporous shale, which would help evaluate adsorbed and free oil. In this paper, models were developed to estimate the amount of oil confined in nanoporous shale and that is mainly in adsorbed and free states to describe the characteristics of oil accumulation. The models were established for an adsorption saturation situation, and simultaneously considered the multilayer adsorption of an oil mixture and the microstructure of the shale pore system (including pore-throat-fracture). As a case study, adsorbed and free oil in lacustrine shales with different lithofacies, obtained from th...


Abstract The author presents an overview of ideas about physis as written by both TA and non-TA authors. He explores the scope of these ideas and applies them to the learning process. He adds ideas of his own about physis, some of which combine those of other theorists and others of which are original. The article ends by bringing these ideas together in a cocreative view on learning from the perspectives of both the learner and the educator, a process driven by their shared stream of energy and at the same time separated by their individual longings and aims.


T~E important discovery that though diamonds are usually non-conducting, they conduct eleclricity under ultra-violet irradiation was first made by Gudden and Pohl (1921). These authors noticed that two of their diamonds showed remarkable differences in behaviour, both in respect of the magnitude of the effect as well as its spectral variatiom One non-¡ crystal which transmitted the ultraviolet spectrum down to ~ 2300 was found to be much more photo-conducting than another which was fluorescent and absorbed ultra-violet radiations of lesser wavelength than ~ 3000. Later workers, notably Robertson, Fox and Martin (1934) have investigated the problem in detail. Ah examination of their data indicates that diamonds show a highly diversified behaviour, the photoconductivity ranging from a very high to a very Iow value, through successive stages. Pant (1944) who first drew attention to this situation studied the photoconductivity of thirtysix cleavage plates of diamond and arranged them in a regular sequence. He found that the photoconductivity is closely correlated with similar variations in other properties of diamond, notably its ultraviolet transparency and the colour and intensity of its luminescence under ultraviolet irradiation.


A program for automated waste mixture identification (PAWMI) was developed as a preliminary screening tool for unknown organics handled on remedial action sites. PAWMI has three subroutines: the interferogram processing and peak selection subroutine (PUSHSUB), the interpretation subroutine (PAIRS), and final processing subroutine to subtract spectral similarity (PAIRPLUS). The method can be used to interpret spectra generated with both transmission and internal reflection techniques. The qualitative limit of detection of minor components in mixtures tested with PAWMI ranged from 0.4% to 15%, depending on the spectral similarity of components of the mixtures. The sensitivity of the method was 77%. False positives represented 13% of the total positive results reported.


Cyclic s-cyano ketones like cyanocarvone and 3-cyano-2-methylcyclopentanone can be annelated in high yields with methyl vinyl ketone, ethyl vinyl ketone and 6(3- methoxyphenyl)hex-1-en-3-one to cyano-substituted decalones and indanones. Computational studies at the B3LYP/6-31+G(d,p)//B3LYP/6-31G(d,p) level of theory show that thermodynamic rather than kinetic factors can explain the high yields. The annelated products are suitable intermediates for the synthesis of isoprenoid, steroid and homo steroid skeletons


To conserve power while ensuring good performance on resource-constrained mobile devices, devices transition between different Radio Resource Control (RRC) states in response to network traffic and according to parameters specific to network operators. As RRC states significantly affect application power consumption and performance, it is important to understand how RRC state timers interact with network traffic patterns. In this paper, we show that the impact of RRC states on performance is significantly more complex and diverse than found in previous work. To do so, we introduce an open-source tool that allows the impact of RRC states on network and application performance to be measured in a robust and accurate manner on unmodified user devices, and deploy the tool in 23 countries around the world to test a broad range of cellular network technologies. We detect previously unknown performance problems which increase network latencies by up to several seconds and for LTE, can increase packet losses by an order of magnitude. Through an in-depth cross-layer analysis of several carriers, we examine the lower-layer causes of these problems. We determine that the highly complex state transitions of certain carriers, and in particular poor interactions between state demotions and network traffic, can lead to substantial, unexpected latencies.

Variable-stiffness modules add significant robustness to mechanical systems during forceful interactions with uncertain environments. Traditionally, most existing variable stiffness modules tend to be bulky by virtue of their use of solid components making them less suitable for mobile applications. In recent times, pretensioned cable-based modules have been proposed to reduce weight. While passive, these modules depend on significant internal tension to provide the desired stiffness and stiffness modulation capability tends to be limited. In this paper, we present design, analysis and testing of a cable based active variable stiffness module that can be realized to achieve a large stiffness range. Controlled changes in structural parameters (independent of cable length actuation) now permits independent modulation of the perceived stiffness with desired tension. This capability is now systematically evaluated on a hardware-in-the-loop experimental setup and results are analyzed.Copyright © 2014 by ASME


This paper describes the implementation on a transputer system of a macroparallel algorithm for dynamics simulation of a multibody chain. The experimental results demonstrate that one can improve eficiency of computation for this problem by exploiting macroparallelism. However, analysis of the performance shows that the serial component of the macroparallel algorithm contributes significantly to the overhead incurred in the implementation and therefore, limits the speedup that can be achieved with this approach.


1. Moore mainly uses the term unseen labour to refer to the creation of digital personality and reputation management in order to attract (typically algorithmically) work through digital platforms. Following Hardt and others, she distinguishes affective labour from mere emotion and emotional labour. The latter is a visible production of affective labour, which involves relational enabling or disabling of the capacity to act (emotion is reaction).


This paper presents the Radar Echo Emulator (REE), a SAR simulation tool with high fidelity and flexibility that is being used to assess and quantify the radar instrument functionality, performance, and overall impulse response for various modes of the NASA-ISRO synthetic aperture radar (NISAR) mission. NISAR is a complex multi-channel multi-polarization wide-band wide-swath high-resolution SAR instrument based on SweepSAR architecture [1]. Its radar instruments support several configurable radar modes to fulfill variety of science applications [2]. The paper provides a brief overview of the REE tool as a general SAR simulator while primarily focusing on its SweepSAR and digital beamforming (DBF) application via an example of repeat-pass four-channel L-band split-spectrum NISAR simulation over an extended Amazon rainforest-like scene [3], [4]. An example of the ionosphere effect with split-spectrum analysis and an example with radio frequency interference (RFI) contamination are also presented.


Web applications are complex sophisticated programs that are based on novel computing technologies. Web applications are popular due to the omnipresence of web browsers and the convenience of using web browser as a client. The ability to update and maintain web applications without distributing and installing software on potentially large number of client computers is a key reason for its popularity. Modern web sites enables the capturing, processing, storage and transmission of sensitive customer data for immediate and recurrent use and that is made possible only through the web applications. Web applications are quickly deployed anywhere at no cost and without any installation requirements at the user end. Although powerful, these technologies bring new challenges for developers and testers. As a result, all entities of web application have to be tested. Due to market pressure and high configuration cost of software testing the web application functional testing is often neglected by the developers. No doubt, there a number of web application testing tools available but these tools use traditional techniques which are not suitable for complex structured web applications. The traditional techniques lack the additional features of testing such as regression testing, fixing errors, uniquely identifying hypermedia, testing database connection etc. In the proposed work CWEBTEST testing tool has been developed to overcome the problems of regression testing of web applications. CWEBTEST testing tool test web applications based on unique hypermedia. With the CWEBTEST tool hypermedia are identified from the complied HTML code and then regression testing is performed. The developed tool improves the efficiency by reducing 10-25% test data size. Moreover, resource utilization is improved as compared to existing testing techniques. The tool has been published on Microsoft public cloud environment for experimental purpose and the performance has been found to be satisfactory.


as the occurrence of annoying nasal symptoms including discharge, itching, sneezing, congestion and pressure. Rhinitis can be classified into three basic categories, based on its cause:
o Allergic rhinitis – caused by allergy to e.g. pollen, animal dander, house dust mites etc.
o Non-allergic rhinitis – caused by e.g. tobacco smoke, strong fragrances, changes in temperature etc.
o Infectious rhinitis – usually caused by viral infection


ABSTRACT Shipbuilding is a complex systematic project involving various processes. In this study, a function-oriented quality control method is proposed to control shipbuilding quality effectively. The method decomposes the ship construction process from the functional perspective to study the relationship between the intermediate products and the functions, afterwards analyse the impact mechanism of the construction process on the function. The improved failure mode and effects analysis with fuzzy evaluation method is conducted to determine the weak link of processes and develop process optimisation measures. As a practical application, the quality control of the propulsion shafting installation is conducted using the method, which proves its feasibility and effectiveness.


I long to get into the country; for my health, latterly, is not quite what it has been, for many years past. I should not long stand such a life of bodily inactivity and mental exertion as I have led for the last few months. An hour or two of daily labor in a garden, and a daily ramble in country air or on the seashore, would keep all right. Do not allude to this matter in your letters to me; as my wife already sermonizes me quite sufficiently on my habits-and I never own up to not feeling perfectly well. Neither do I feel anywhere ill, but only a lack of physical vigor and energy, which re-acts upon the mind.'


Since the beginning of 21st century,as China's industrialization and urbanization goes quickly,steel production climbs up largely based on a strong demand of iron ores.In particular,from 2004 to 2009,a rapid growth of imported iron ores resulted in a continuous rise in price.According to the short-term model of mineral resources constraints on economic growth,constraints of iron ore resources to China's economic growth is measured via 2001—2009 iron ore export import data and GDP data,demonstrating a continued-rising influence to the absolute value of economic growth,from 0.42% in 2004 to 2.92% in 2009.Iron ore resource is a big constraint to China's economic growth especially to industrial growth in a short term,but still remains a strong influence for a long time in the future.


In order to efficiently collect data, it is essential to locate the facilities and analyze the movement data. The current technology for location collection can collect data using a GPS sensor, but GPS has a strong straightness and low diffraction and reflectance, making it difficult for indoor positioning. In the case of indoor positioning, the location is determined by using wireless network technologies such as Wifi, but there is a problem with low accuracy as the error range reaches 20 to 30 m. In this paper, using BLE 4.2 built in Raspberry Pi, we implement Bluetooth Smart Ready. In detail, a beacon was produced for Advertise, and an experiment was conducted to support the serial port for data transmission/reception. In addition, advertise mode and connection mode were implemented at the same time, and a 3-count gradual algorithm and a quadrangular positioning algorithm were implemented for Bluetooth RSSI error correction. As a result of the experiment, the average error was improved compared to the first correction, and the error rate was also improved compared to before the correction, confirming that the error rate for position measurement was significantly improved.


Aroma is one of the essential parameters that determine fruit quality. It is also an important feature of varietal characterization and so valuable for agro-biodiversity identification and preservation. In order to characterize changes in the aroma fingerprint through fig development, the main objective of the present research was to study the volatile organic compound (VOC) profiles of figs (Ficus carica L.) from three cultivars, Taamriwthe (TH), Azegzaw (AZ), and Averkane (AV), at three ripening stages (unripe, ripe, and fully ripe). Analyses was performed using Headspace Solid-phase Microextraction and gas chromatography coupled with mass spectrometry. Results revealed the presence of 29 compounds that were grouped into different chemical classes. Aldehydes comprised the most abundant VOCs identified in all the studied figs, while alcohols, ketones, and terpenes comprised the minor compounds found in TH, AZ, and AV figs, respectively. Different aroma descriptors were identified throughout the ripening stages of figs; fruity and green aromas were dominant in all cultivars, while a fatty aroma scarcely occurred in figs. A gallery plot representation demonstrated that certain VOCs differentiate the studied cultivars and the different ripening stages of figs. Principal component analysis findings demonstrated characteristic VOCs of distinct ripening stages and cultivars, those VOCs can be used as fingerprints to distinguish different cultivars and/or ripening stages.


While advocating the adoption of qualitative approaches to evaluation, it is important to reflect on the practice. This paper draws on the work of a diversionary project to involve young people at risk in leisure and sporting activities using one to one mentors. The approach adopted was one that was designed to address potentially sensitive issues and place the experience of the key players central to the enquiry. Hence, the intention was that the young people and their mentors should be treated as knowers and actors rather than the objects of the research. The approach discussed here stops short of treating them as 'partners' in the research as discussed previously in this journal, arguing instead for an approach in which skilled researchers actively engage all parties. Such an approach can offer insights inaccessible to more conventional evaluation techniques.


In this paper, various algorithms have been referred for face detection and recognition for security purpose in smartphones. Different types of algorithms such as template matching, color code segmentation using K-mean clustering algorithm, etc. for face detection and KLT for face recognition have been used. In any of the face recognition system the first step is face detection. The mentioned algorithms have first been constructed in MATLAB and then later it is implemented in SMARTPHONES phones. After the implementation of the mentioned algorithms, we have recognized certain pros and cons while implementing the face recognition system on a mobile phone with limited hardware capabilities.

Snoring is an important sign of sleep-related breathing disorders (SRBD), of the upper airway resistance syndrome (UARS), and of the obstructive sleep apnea (OSA). Snoring is a symptom of nasal obstruction and is associated with cardiovascular diseases. Roommates or bed partners are also suffered by snorers. In-house monitoring of snoring is very useful for evaluation by bed partner or roommate as well as polysomnography in sleeping centre. Process to evaluate and monitoring snoring available in the country are mechanical process. Our objective is to evaluate a biochemical process to minimize snoring with two mucolytic expectorants Ambroxol & Bromhexine and compare their performance in non OSA Bangladeshi patients.32 snorers with no other respiratory disease like asthma , bronchitis etc. and who has ESS score 8-16 and SSS score 2-4,were taken from a Sleep Medicine Centre of Japan Bangladesh Friendship Hospital, 15 students from Bangabandhu Sheikh Mujibur Rahman Hall, Jahangirnagar University and another 15 from University of Development Alternative(UODA). The procedure and scoring were performed by help of roommates and bed partners. Snoring was measured on the basis of Frequency, Loudness, Snoring Index and day time sleepiness using Epworth Sleepiness Scale (ESS). A portable respiratory recording device (PRRD )was used to determine loudness, index and frequency of patient at home and snoring data was also collected from sleep medicine centre where polysomnogram was used. snoring severity objectively were also measured by using Snoring Severity Scale (SSS). excellent snoring suppressing effect was observed in both groups after treating separately with Ambroxol and Bromhexine 30 mg per night. Snoring Frequency, Loudness, Severity, Index and ESS score was reduced markedly in compared to placebo group.

Near-IR femtosecond (τ = 150 fs, λ=775 nm, repetition rate 1 kHz) and VUV nanosecond (τ = 20 ns, λ=157 nm, repetition rate 1 to 5 Hz) laser pulse ablation of single-crystalline TeO2 (c-TeO2, grown by the balance controlled Czochalski growth method) surfaces was performed in air using the direct focusing technique. The multi-method characterization using optical microscopy, atomic force microscopy and scanning electron microscopy revealed the surface morphology of the ablated craters. This allowed us to characterize precisely the lateral and vertical dimensions of the laser-ablated craters for different laser pulse energies and pulse numbers at each spot. Based on the obtained information, we quantitatively determined the ablation threshold fluence for the fs laser irradiation when different pulse numbers were applied to the same spot by using two independent extrapolation techniques. We found that in case of NIR femtosecond laser pulse irradiation, the ablation threshold significantly depends on the number of laser pulses applied to the same spot indicating that incubation effects play an important role in this material. In case of VUV ns laser pulses, the ablation rate is significantly higher due to the high photon energy and the predominantly linear absorption in the material. These results are discussed on the basis of recent models of the interaction of laser pulses with dielectrics.
