The rapid mutation of the H1N1 strain of the Influenza virus makes it quite difficult to treat once the infection has spread. The development of new treatments based on the destabilization of the genetic material, regardless of the sequence, is necessary.

The study aims to evaluate the antiviral properties of Pt/TiO2-SiO2 bionanocatalysts against Influenza A (H1N1) virus in a post-infection model and to characterize the morphology of the nanoparticles.

The bionanocatalysts were synthesized by the sol-gel method. Electron Microscopy studies were performed to evaluate the grain size and morphology of pure nanoparticles. Madin-Darby Canine Kidney (MDCK) epithelial cells were infected with Influenza A (H1N1) virus. They were treated with 500 μL of three viral suspensions (1:50, 1:100, and 1:1000) and 500 μL of a nanoparticle suspension (2 ng/mL). The presence of the virus was identified by Polymerase Chain Reaction (PCR) endpoint and the antiviral properties of the nanoparticles were identified in terms of infection reduction calculated by real-time PCR using Influenza A and H1N1 subtype primers. The percentage of infection reduction was calculated by comparing control samples and samples treated with the bionanocatalysts.

The Pt/TiO2-SiO2 bionanocatalysts showed highly surface-dispersed platinum nanoparticles with an average particle size of 1.23 ± 0.36 nm in the amorphous mixed oxide matrix. The nanoparticles showed antiviral properties with a maximum reduction in viral proliferation of 65.2 ± 3.3%.

Pt/TiO2-SiO2 bionanocatalysts were able to reduce Influenza A (H1N1) viral infection 65.2 ± 3.3%; the results suggest the biocompatibility with healthy tissues and in vitro antiviral properties. Further studies should be conducted to identify the concentration required to achieve total virus clearance. However, the outcome of the present work suggests the possibility of implementing bionanocatalysts as treatments for Influenza A (H1N1) virus infection, especially at an advanced stage of infection.


Thirty healthy volunteers, 30 years and older, received one or mope intrauterine instillations of quinacrine (i Kin) in order to obtain a chemically induced occlusion of the Fallopian tubes. Prior patency of the latter was checked either by the Rubin test or by hyster~salpingoKraphy (in 8 patients). Bilateral occlusion occurred in 12 patients after the first instillation; this was shown by the Rubin test~ done for all subiects 4 to 6 weeks after the procedure, and by hysterosalpingoKr~phy in ii out of the 12 patients with a negative Rubin test. From the remainin~ 17 volunteems (one opted out)~ II cases of occlusion were obtained after a second instillation. Three patients received a third instillation, with positive results in two. Thus bilateral occlusion was produced in 25 out of the 30 referred patients. So far II patients were seen in follow-up 6 to 8 months after the last instillation; in all cases hysterosalpingographv confirmed the lon~ lasting state of occlusion.


Incidents cause substantial travel delays on urban freeways. Travel delays due to incidents are typically estimated for each incident independently. However, when multiple incidents occur on the same stretch of a roadway, treating them independently and ignoring their interactions leads to inaccurate results, which ultimately may lead to inefficient incident management strategies. This study examines delays due to primary–secondary incident pairs that occur on the same stretch of a freeway within a short time gap. Depending on their correlation in time and space, they can have varying degrees of impacts on the traffic flow. This article assesses the total delays induced by primary–secondary incident pairs by jointly modeling their occurrences. First, incident data combined with roadway inventory data from Hampton Roads, Virginia, are analyzed to understand the attributes of primary–secondary incident pairs, e.g., durations, lane blockages, and time gaps (between start times of the primary and its secondary incidents). Then using microscopic simulation as a primary evaluation tool, the effects of three critical parameters are investigated: time gap, distance between primary and secondary incidents, and traffic demand level. The historical incident analysis shows that, on average, primary–secondary incident pairs have substantially longer durations than single incidents. The joint analysis of queuing delays induced by primary incident and its secondary incident suggests that time gap and distance between a primary incident and its secondary incident are significantly associated with the total delays after controlling for other factors (e.g., the two associated incidents' durations and lane blockages). Furthermore, based on the scenarios tested (i.e., two incidents both blocking the right lane in a three-lane basic freeway section), it is found that the sum of delays induced by a primary incident and its secondary incident separately will over- or underestimate the actual delays. For those secondary incidents that end after their associated primary incidents, total delays increase as time gap increases; increasing the distance between primary and secondary incidents is associated with reduction in delays. Other results and the implications of the findings for traffic operations are presented in the article.


Objective: Human brain has features with high fat, high density, difficulty in deep and even labeling, and strong background fluorescence, which made it uneasy to get high-resolution imaging. To solve the above problems, this study successfully explored a new method for human brain transparency called dFC-Tesos by steps including human brain tissue electrophoresis degrease, antibody labeling, decolorization, transparency, three-dimensional high-resolution imaging, to clearly observe the spatial relationships and pathological changes between microglia and Aβ plaques in Alzheimer's disease.
Methods: The 3 mm thick slices of the superior temporal gyrus of the human brain were sectioned by a vibration slicer, then degreased in 4% SDS solution with 3 V, 0.01 A electric field until the brain slices were lightly permeable and the interface between gray matter and white matter was fuzzy. Antibodies of microglia were incubated and Aβ plaques were stained by thioflavin S. Additionally, to exclude endogenous fluorescence interference of the samples, the brain slices were decolorized by 8% ammonia, hydrogen peroxide containing 0.08% KOH and 25% N,N,N,N-tetra(2-hydroxypropyl) ethylenediamine (w/v), respectively, which successfully reduced the interference of vascular auto-fluorescence and improved the imaging quality. Human brain tissue transparency was accomplished by tert-butanol gradient degreasing, tert-butanol, and tetraethylenediamine dehydration, benzyl benzoate, bisphenol A ethoxylate diacrylate and tetraethylenediamine for refractive index matching. They were then imaged by LS18 lightsheet micro-imaging instrument with a resolution of 1.65 μm × 1.65 μm × 3.5 μm.
Results dFC-Tesos method was sequentially performed by electrophoretic degreasing of human brain samples, electrophoretic antibody labeling, decolorization, transparent human brain sample preparation, light-sheet microscopy, and splicing of big data to successfully obtain ultrastructural information and spatial location relationships of microglia and Aβ plaques in Alzheimer's disease (AD) brain, which provided methodological support for the study of new mechanisms of the pathology of AD. The dFC-Tesos method also provided an important tool for the study of macroscopic and ultrastructural structures of the pathological brain, the mechanism of major brain diseases, as well as the study of drug targets, and so on.


Abstract The paper presents the processing and mechanical characterization of chopped carbon fibre reinforced homogenous and functionally graded vinyl ester composites and also reports on their sliding wear characteristics respectively. The sliding wear characteristics are studied with the help of POD test employing the design of experiments approach based on Taguchi's orthogonal arrays. Dynamic mechanical analysis is carried out of the investigated homogenous/FGMs composites to investigate the overall stiffness/flexibility, so as to improve the specific wear rate. Present study reveals that graded composite possess good mechanical and wear characteristics compared to homogenous composites. SEM confirms the graded dispersion of carbon fibre in the matrix.


This year is the 200th anniversary of the first published description by James Parkinson of the disease that would come to bear his name. To mark this occasion this special issue of Journal of Parkinson's Disease features invited commentaries by those responsible for some of the greatest advances in understanding and treating the disease since it was first characterized, describing how these advances came about and their lasting impact, with the advantage of hindsight. We are indeed fortunate to have contributions from many of those who played key roles in reaching these milestones in Parkinson's disease research. In a wonderful piece of storytelling, Oleh Hornykiewicz recounts the remarkable mixture of science, intrigue and politics behind his work in the 1950's and early 1960's that triggered the modern era of Parkinson's disease research: the discovery of the dopamine deficit in the brain of patients with Parkinsons'. My Co-Editor-in-Chief Bill Langston relates the fascinating string of events in the 1980's that led him to discover the toxic effects of MPTP on nigral dopamine neurons. This led to the development of several important animal models for the disease and provided early insight into the possibility that mitochondrial dysfunction and oxidative stress could be important players in disease pathogenesis. In the 1990's the pace of important discoveries increased dramatically. In terms of treatment, two advances stand out. Anders Björklund and Olle


In this paper, I offer a possibility of translation into Brazilian portuguese of two short discourses which are dialexeis in genre and are credited to the Greek rhetor Choricius of Gaza (VI AD), as well as a brief commentary. Both texts are important because they bring forth information on the relationship between rhetoric (especially declamation) and visual arts (painting, sculpture, dance, poetry) in Late Antiquity. Declaimers, as much as other mimetic artists, had to impersonate in a convincing way the characters they imitated. This being, we frequently notice the analogy between declaimer and actor/dancer/poet, a topic which is explored in both dialexeis translated here.


The increase of non-linear loads in the supply network, specifically the proliferation of harmonic type loads are research topics. This paper presents the results of some simulations for the harmonics mitigation in distribution systems at the point of common coupling (PCC). This mitigation strategy was centered in the implementation the different phase shifting transformers with 30 degrees apart for the electrical feed of harmonic loads. The models of nonlinear loads and phase shifting transformers are implemented and studied in ATP-EMTP. The simulations for the study cases are performed on an IEEE test feeder 14 nodes. The simulations show a reduction of the harmonic levels in electrical distribution systems, specifically at the point of common coupling with the installation of Phase shifting transformers with connections Dy1, Dy11 and Dz0 and similar harmonic loads.


We review approximation methods and their stability and applicability. We then focus on the finite section method and Galerkin methods and show that on separable Hilbert spaces either one can be interpreted as the other. In the end we demonstrate that well‐known methods such as the finite element method and polynomial chaos expansion are particular examples of the finite section method; their applicability can therefore be studied via the latter.


We demonstrate ultrafast optical signal processing up to bitrates of 170 Gbit/s. Silicon-on-insulator waveguides are defined by CMOS technology. In addition, an organic cladding pro-vides either X(3) or X(2)-nonlinearities that are not impaired by two-photon absorption. With a proper waveguide design, the influence of two-photon absorption in silicon is greatly reduced.


The main contribution of this paper is the development of a novel load shedding methodology so as to regulate unacceptable frequency deviations, with least disruption of service, in the case of controlled islanding. To achieve this, an abstracted model of each islanded area, consisting of one lumped generator and turbine model, is used. Since in the controlled islanding the bounds of the areas are determined, a good estimation of the generation-load mismatch can be obtained. Taking advantage of the latter an amount of load to be shed in the load-rich areas, at the moment of the area separation is proposed. This amount is optimally selected so as to minimize the total load shed, taking into account the primary frequency control dynamics and the conventional Underfrequency Load Shedding schemes (UFLS). Markov Chain Monte Carlo (MCMC) methods and Model Predictive Control (MPC) are the two optimization tools that are used to solve the resulting optimization problem. The effectiveness of the proposed technique is evaluated via simulation on the IEEE 118 bus network.

Understanding the past SARS event will lead the public health decision-makers to face the terrible attack of viruses in the future. An efficient decision of public health may increase the health workers' recognition of protecting themselves. This paper intends to lead a reflection on SARS crisis and human right.


In retail industry, warehousing is the main activity. The warehouse can also function as a product distribution center (DC) to consumers or retailers. Distribution centers have an important role in supply chain management. DC performance is strongly influenced by many factors. One of them is picking order performance, which is a product taking operation from a certain storage place ordered by consumer. Total picking time is influenced by picker operator activity, which includes searching activity, traveling / transportation, taking, setting, and other activities/idle. The researched examined the possibility of redesigning the layout and structuring of products on the warehouse rack shelf so as to minimize picking time process. The method to be used in design is the group technology method. Based on the results in a retail industry in Bandung, the completion of the picking time is better by decreasing the average picking order completion time around 61.65% of the current system.

To address poverty, many rural communities mobilized tourism at the grassroots level in Indonesia. Such manners raised the government's concern about potential social-environmental problems, motivating them to collaborate with academia to develop responsible tourism through placemaking. Meanwhile, studies evaluating the success/failures of placemaking in the rural context remain limited. This article aims at qualitatively assessing the capacity of rural placemaking to motivate community participation by using the Trucuk sub-village in Bantul Regency as the case study. Methods employed are semi-structured interviews, observations, and document reviews. Using the theories of Arnstein, Innes and Booher, and Project for Public Space as its framework, this study found that the lack of community participation from the ground rules establishment and negotiations of power redistribution, awareness development of making use of local capital to affect outcomes, and diverse opinions in planning led to declining interest of the community in participating. Future planning should address those issues by ensuring the involvement of diverse groups within the community, employing innovative and interactive methods to foster participation, evaluating the representativeness of the tourism awareness group, and setting a considerable limit on the authority's dominance in the planning.


We present spectroscopic and photometric analysis of the quintuple star HD 86222 with an eclipsing component. Until now three visual components A, B, and C of this multiple star were known. Four components in the A/B pair were detected during the examination of the cross correlation functions obtained from the spectra. We noticed that the visual components A and B, separated by , are in fact two binary stars – one eclipsing pair and one spectroscopic system. The pair with higher radial velocity amplitude corresponds to the eclipsing period. Photometric and spectroscopic observations of the eclipsing binary enable us to obtain the Wilson-Devinney model. The masses of this pair are M1 = 1.29 ± 0.09 M⊙ and M2 = 1.33 ± 0.09 M⊙, respectively. The radii, slightly higher than for the main sequence stars, are R1 = 1.35 ± 0.01 R⊙ and R2 = 1.36 ± 0.01 R⊙, respectively. The main parameters of the spectroscopic binary are also estimated, but they must be confirmed by future observations because of the uncertainty of the period. The farthest star named C, is 15 arc seconds from the main A and B components. Assuming that this object is gravitationally connected with the A and B binary pairs, HD 86222 has at least five components.


In Icelandic, as in many other languages, phrasal compounds are an interface phenomenon of the different components of grammar. The rules of syntax seem to be preserved in the phrasal component of Icelandic compounds, as they show full internal case assignment and agreement. Phrasal compounds in Icelandic can be divided into two distinct groups. The first group contains common words which are part of the core vocabulary irrespective of genre, and these are not stylistically marked in any way. Examples of these structures can be found in texts from the 13th century onwards. The second group contains more complex compounds, mainly found in informal writing, as in blogs, and in speech. These seem to be 20th century phenomena. Phrasal compounds of both types are relatively rare in Icelandic, but other types of compounding are extremely productive. Traditionally, Icelandic compounds are divided into two groups, i.e., compounds containing stems and compounds containing inflected word forms, mostly genitives, as non-heads. Phrasal compounds in Icelandic also have genitive non-heads, raising questions on the difference between the processes in non-phrasal and phrasal compounding in Icelandic.

The Joint Maximum Likelihood (JML) criterion is used to derive the optimal recursive-iterative estimator for discrete nonlinear dynamic systems. For linear systems this approach constitutes, in its recursive form, the structure of the Kalman Filter. The JML approach to estimation of nonlinear systems can be solved by batch formulas at the cost of extensive computational effort, i.e. with each new measurement the for derivation of the new estimate all available data has to be processed. This paper presents recursive-iterative implicit closed form solution that gives formulas of the optimal estimator, i.e. gives the value of the optimal estimated state. The computation of the estimator's gains needs the solution of non-symmetric Difference Matrix Riccati Equation (DMRE).


The group solution model of Ratcliff and Chao for the excess free energies of liquid mixtures has been tested and found satisfactory for six mixtures of alcohols and aromatic hydrocarbons. The model was tested by comparing experimental and predicted vapor-liquid equilibrium data.

The assumption that aliphatic and aromatic carbon atoms are equivalent appears satisfactory for the mixtures considered. Group contribution functions were generated from experimental data on ethanol/benzene mixtures at 45°C, and are presented. These functions allow the prediction of excess free energies of mixtures containing alcohols and aromatic hydrocarbons at 45°C. No experimental data is required. Predictions at temperatures close to 45°C, using the same functions, should be satisfactory.

The group contribution functions were close to those generated previously from alcohol/alkane data. The latter may be used for predicting excess free energies of alcohol/aromatic hydrocarbon mixtures with little loss of accuracy.

On a fait l'essai du modele de solutions pour groupes de Ratcliff et Chao (servant a determiner les energies libres en exces de melanges liquides) dans le cas de six melanges d'alcools et d'hydrocarbures aromatiques. L'essai du modele s'est fait en comparant les donnees experimentales et prevues pour l'equilibre entre vapeur et liquide. La supposition que les atomes de carbone aliphatique et aromatique sont equivalents a paru satisfaisante pour les melanges d'ethanol et de benzene a 45°C et les presentes. Les dites fonctions permettent de prevoir les energies libres en exces de melanges contenant des alcools et des hydrocarbures aromatiques a 45°C, sans avoir recours a des donnees experimentales. Les predictions faites a des temperatures voisines de 45°C, en utilisant les fonctions en question, devraient ětre satisfasantes. Les fonctions contribuantes des groupes se sont averees rapprochees de celles qu'on avait obtenues precedemment a partir de donnees sur l'alcool et les alcanes; on peut les utiliser pour prevoir les energies libres en exces de melanges d'alcools et d'hydrocarbures aromatiques, et ce avec une perte minime d'exactitude.


Cardiovascular disease (CVD) is the largest cause of mortality in the world with around 17.7 million victims each year 1 CVDs include coronary heart disease, ischemic heart disease, rheumatic heart disease, cardiomyopathies, and other diseases involving the heart and circulatory system. However, in contrast to the progress made in high-income countries, the burden of CVD and other noncommunicable diseases have only continued to rise significantly in low and middle-income countries, especially India. It is estimated that nearly 80% of CVDs will be burdened by developing countries by 2020.2 Interestingly, India has been disproportionately impacted by these CVDs. In India, the average age of 59 for heart failure patients is approximately ten years younger than the average age for heart failure (HF) patients in South America and China 3 In contrast to most western countries, HF is prevalent in both the young and elderly in India.4 Moreover, India's estimated age-standardized death rate of 272 per 100,000 population due to CVDs is greater than the global average of 235 per 100,000 population5 Both environmental and genetic factors are argued to contribute to this increased CVD susceptibility. 6 India has begun to research and implement innovative policies and interventions to help tackle this and achieve the WHO target goal of a 25% reduction in premature deaths from noncommunicable diseases by 2025.

Porous electrodes with nanosheets vertically aligned to the substrate are candidates for high power energy storage applications such as rechargeable batteries and electrochemical capacitors due to the shortened ion and electron transfer pathway. Here we fabricate vertically aligned reduced graphene oxide (rGO) films by combining electrophoretic deposition and ice template methods. As deposited and freeze-dried films prepared from graphene oxide dispersion show perpendicular orientation of graphene oxide with a tilt angle of 85 ± 9° with respect to the substrate. The film thickness and pore sizes are varied from 50 to 200 μm and from 10 to 100 μm, respectively, by changing the freeze-drying conditions. The vertical alignment of nanosheets enhances the specific capacitance and charging rate behavior. At a high scan rate of 500 mV s–1, the specific capacitance was approximately 78% of that at 2 mV s–1, indicating an improvement in the rate performance due to the perpendicular orientation.


The objective of the present study was to determine the optimal dose substitution of water hyacinth flour (Eichhornia crassipes) in feed on the growth performance of Bileh (Rasbora sp.) fingerlings. The Completely Randomized Design (CRD) used in this study consisted of four treatments and three replications. Four doses of Eichhornia crassipes were tested: P0 = Feed without substitution of fermented water hyacinth flour as control, P1 = The substitution of fermented water hyacinth flour 5% in feed, P2 = The substitution of fermented water hyacinth flour 10 % in feed, P3 = The substitution of fermented water hyacinth flour 15% in feed. Bileh used as test fish have a length range of 2-2,5 cm. Feed was given three times with at satiation method. Bileh is stored for 30 days. The results showed that the absolute weight growth, absolute length growth, specific growth rate, and feed efficiency were higher in substituting 15% water hyacinth flour in Feed (P3). However, the substitution of water hyacinth flour in Feed had no significant effect on the survival rate and daily growth rate of bileh (P>0.05). The best dose of substitution of water hyacinth flour to increase the growth of Bileh fish and is more economical is 15% in Feed.


Hypoxia, a condition of low oxygen tension, occurring in many pathological processes, modifies the mononuclear phagocyte transcriptional profile. Here, we demonstrate hypoxic up‐regulation of the CCL20 chemokine in primary human monocytes (Mn) and macrophages. mRNA induction was paralleled by protein secretion and dependent on gene transcription activation. Functional studies of the CCL20 promoter using a series of 5′‐deleted and mutated reporter constructs demonstrated the requirement for the NF‐κB‐binding site located at position –92/–82 for gene transactivation by hypoxia, as 1) transcription was abrogated by a 3‐bp mutation of the NF‐κB motif; 2) three copies of the wild‐type NF‐κB‐binding site conferred hypoxia responsiveness to a minimal heterologous promoter; and 3) hypoxia increased specific NF‐κB binding to this sequence. Furthermore, we provide evidence of the specific role of a single NF‐κB family member, p50, in mediating CCL20 gene transcription in hypoxic Mn. p50 homodimers were the only detectable NF‐κB complexes binding the cognate κB site on the CCL20 promoter upon hypoxia exposure, and NF‐κBp50 knockdown by lentiviral‐mediated short hairpin RNA interference resulted in complete binding inhibition. NF‐κBp50 overexpression in transient cotransfection studies promoted CCL20 gene transactivation, which was abrogated by mutation of the –92/–82 κB site. Moreover, nuclear expression of the other NF‐κB family members was inhibited in hypoxic Mn. In conclusion, this study characterizes a previously unrecognized role for hypoxia as a transcriptional inducer of CCL20 in human mononuclear phagocytes and highlights the importance of the NF‐κB pathway in mediating this response, with potential implications for inflammatory disease and cancer pathogenesis.


When the first PCs were deployed in industrial automation environments during the 1980s, it was difficult to imagine how the information technology (IT) would influence the day to day operations of industrial organizations. For the last decade or so, the convergence of operational technology (OT) and information technology has been an important topic in organizations whose operations rely on industrial control systems.
 The advantages of the IT/OT convergence are obvious – cost reduction, improved capabilities or greater efficiency. However, these advantages come with a cost as they have affected the way that industrial control systems operate and increased the exposure of ICS to cyber risks.
 According to one research study, nearly 90% of organizations with connected OT infrastructures have experienced a security breach within their Supervisory Control and Data Acquisition and Industrial Control Systems (SCADA/ICS) architectures, with more than half of those breaches occurring in just the previous 12 months.


A second-generation passive millimeter-wave imaging system is being prepared for flight testing on a UH-1H "Huey" helicopter platform. Passive millimeter-wave sensors form images through collection of blackbody emissions in the millimeter-wave portion of the electromagnetic spectrum. Radiation at this wavelength is not significantly scattered or absorbed by fog, clouds, smoke, or fine dust, which may blind other electro-optic sensors. Additionally, millimeter-wave imagery depends on a phenomenology based on reflection rather than emission, which produces a high level of contrast for metal targets. The system to be flight tested operates in the W-band region of the spectrum at a 30 Hz frame rate. The field-of-view of the system is 20 x 30 degrees and the system temperature resolution is less than 3 degrees. The system uses a pupil-plane phased-array architecture that allows the large aperture system to retain a compact form factor appropriate for airborne applications. The flight test is to include demonstrations of navigation with the system in a look-forward mode, targeting and reconnaissance with the system in a look down mode at 45 degrees, and landing aid with the system looking straight down. Potential targets include military and non-military vehicles, roads, rivers, and other landmarks, and terrain features. The flight test is scheduled to be completed in April 2004 with images available soon thereafter.

Studied in this paper is the control problem of hyperchaotic systems. By combining Takagi–Sugeno (T–S) fuzzy model with parallel distributed compensation design technique, we propose a delay-dependent control criterion via pure delayed state feedback. Because the result is expressed in terms of linear matrix inequalities (LMIs), it is quite convenient to check in practice. Based on this criterion, a procedure is provided for designing fuzzy controller for such systems. This method is a universal one for controlling continuous hyperchaotic systems. As illustrated by its application to hyperchaotic Chen's system, the controller design is quite effective.


This article presents some results of measurements and analysis of mechanical vibrations of a railway track with intermediate rail fasteners such as Pendrol and KPP-5 under the vibrodynamic influence of rolling stock. The results obtained can be used as one of the criteria for justifying the choice of the most optimal type of rail fasteners.

Online discussion forums are one of the most ubiquitous kinds of resources for people who are learning computer programming. However, their user interface - a hierarchy of textual threads - has not changed much in the past four decades. We argue that generic forum interfaces are cumbersome for learning programming and that there is a need for a domain-specific visual discussion forum for programming. We support this argument with an empirical study of all 5,377 forum threads in Introduction to Computer Science and Programming Using Python, a popular edX MOOC. Specifically, we investigated how forum participants were hampered by its text-based format. Most notably, people often wanted to discuss questions about dynamic execution state - what happens "under the hood" as the computer runs code. We propose that a better forum for learning programming should be visual and domain-specific, integrating automatically-generated visualizations of execution state and enabling inline annotations of source code and output.


One of the major problems of the environment is the landslide and the forest plays an important role in this problem. In our country in the latest years had place massif deforestation. One possible solution of this is the forestation and for the good results are necessary studies of the growth for the forest. We start to study this issue in the paper [1].
Soil erosion and landslide are some of the prevalent land degradation process on Romania. The land with slope greater than 5% represents 67% from the territory of Romania. The fast soil erosion is favoured by the geomorphologic and litological conditions. The decreasing of the areas covered by forest represents the most important factor for the soil degradation. The surface covered by forest represents 27% from the territory of Romania.


In order to address the routing security problem of VANETs,a novel trusted routing protocol is proposed based on experienced trustiness.From the view of objective trust,a model introduces the concept of experienced trustiness as trust metrics.Also some recommendatory methods to calculate the experienced trustiness and reputation are given.And a new forwarding rule is designed according to experienced trustiness.The simulations show that the proposed trust scheme has better ability than GPSR(greedy perimeter stateless routing) protocol on accommodating selfish nodes.

The aorta coarctation (CoA) is one of the most common congenital heart diseases (CHDs). It is defined by a narrowing in the proximal thoracic aorta and is treated through surgery or stent placement. Advances in medical imaging and computational techniques provided the research community with a unique opportunity to investigate CHDs, with computational fluid dynamics (CFD) models opening new ways to understand cardiovascular pathologies. Due to the complexity of the cardiovascular system, it is common to model merely the region of interest and represent the remaining circulation through boundary conditions (BCs), whose choice is critical for CFD since different BCs could lead to quantitative differences in the solution. This work presents a framework to adjust Murray's law BC, using an optimisation approach. Taking Murray's law parameter as the control, the approach uses a discretise-then-optimise methodology to numerically solve the control problem. The framework was tested using generated in-silico data sets and then applied to a realistic 3D geometry representing a CoA, using patient-specific data, for validation. The results show small errors over the domain, with absolute errors < 1% and relative errors <10%. The largest relative errors were found in the supra-aortic outlets when different types of BCs were attributed in the in-silico data and in the controlled problem, whilst the absolute errors kept minor (<1.5%). For the normal aorta and CoA, the parameters obtained are different from those found in the literature, with higher parameter values found for the CoA, which can be explained by the flow behaviour.


Parkinson's Disease patients attending traditional long-term rehabilitation programs may lose interest and eventually drop out, as a direct result of the repeatability of the prescribed exercises. Technology-supported opportunities in the form of character-based, virtual reality exercise games (called "exergames") can engage players to train in a non-linear fashion by providing an experience which varies from one game loop the next. The present work reports on a Kinect-based Unity3D exergame tailored to PD patients with mild to moderate symptoms which can be used in both clinical and home settings. The game supports a collection of gestures drawn from existing PD-specific training programs which advocate big and purposeful movements, intended to improve postural stability and reflexes as well as increase the overall mobility of upper and lower limbs. When a patient's movements "match" a programmed gesture, a 3D cartoon avatar responds accordingly. Finally, in-game decision-making purports to improve the patient's cognitive reaction.


This article provides a compact overview of the history, technology, and performance of MPEG Surround. The technology of MPEG Surround is based on the spatial audio coding (SAC) principle: In the encoder, a mono- or stereophonic down- mix is generated from the multichannel input signal, and additional parametric side information is extracted to guide the subsequent up-mix procedure in the decoder.With Moving Pictures Expert Group (MPEG) Surround, a data-rate efficient coding scheme for high-quality multichannel sound using novel parametric coding techniques has been standardized.


Surface warming since 1950 in the off‐equatorial south Indian Ocean (IO) occurs without a consistent surface heat flux trend, and is accompanied by a shoaling thermocline. The associated dynamics have not been fully explored. Using 20th century climate model experiments, we test if the shoaling thermocline is attributable to a transmission from the Pacific, where a similar shoaling occurs, and whether it is climate change‐induced. A 22‐model average produces no such signal. An average of a subset of models that better simulate El Niño‐Southern Oscillation (ENSO) and its transmission produces the right direction of the IO thermocline trends. The shoaling in this subset average, taken as anthropogenically induced, is far weaker than the observed, suggesting a significant multidecadal variability component in the observed changes. The Pacific contribution increases with a stronger model ENSO amplitude and broader meridional structure, highlighting the importance of realistic ENSO simulations in modelling long‐term change in the IO.


In 1967 MacCormack observed: "The number and diversity of the views expressed on nexum have become notorious; even today no agreement has been reached." All that seems to be clear is that nexi were debt-"slaves." While progress has been made, including by MacCormack himself, there remain major gaps in our understanding. This paper deals with two central questions: (1) What is a nexumcontract?; (2) Why did it flourish after Rome's enactment of the Twelve Tables? It is suggested that these questions can be answered satisfactorily once it is recognized that reliance on the nexum-contract was encouraged by maximum interest rate laws and legal procedures making it more difficult (costly) to enslave defaulting debtors.


Small-angle neutron scattering (SANS) measurements of syndiotactic s-PMMA polymers mixed with weakly attractive 1.0 nm diameter polyhedral oligomeric silsesquioxane (POSS) nanoparticles (NPs) show no observable changes in the chain radius of gyration Rg, regardless of the polymer molecular weights, the amount of residual solvent, or the POSS NP loading and dispersion (from 0 to 20 vol %). In retrospect, these results are not surprising since scaling arguments imply that chain size in the concentrated region of the phase diagram of a polymer solution is ideal and independent of the polymer volume fraction ϕ, and only as the semidilute region is entered with decreasing concentration does the chain size for a good solvent begin to increase due to polymer excluded volume and then scales with concentration as ϕ–1/8. For typical polymer nanocomposites the NP concentrations are less than 50% v/v, so the polymers are still generally within the concentrated regions of their phase diagrams, where ideal chain confor...


Abstract Herbal essential oil (EO) as a natural and traditional source are considered to be suitable alternatives for controlling chemical resistant strains due to their antibacterial compounds and also no adverse effects. This study was undertaken to identify the chemical compositions and also to assess the antibacterial effects of Froriepia subpinnata (Ledeb.) Baill. (F. subpinnata) EOs before and after flowering against Pseudomonas aeruginosa (P. aeruginosa), for the first time. Based on our findings, 50 and 41 components were identified by gas chromatogram/mass spectrometry (GC-MS) in the before and after flowering EOs of F. subpinnata. The major components of F. subpinnata EOs before flowering were kuminol (42.05 %), phenol (28 %) and its after flowering prominent compounds were sabinin (25.96 %), timol (22.68 %), cyclohexene (17.21 %). Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were obtained 6 % and 8 % for before flowering, and, 4 % and 6 % for after flowering. Also in antibiogram method, both EOs at before and after flowering stages exihibited lower inhibitory effect on P. aeruginosa in comparison with ciprofloxacin, amikacin and imipenem antibiotics. According to the results, the antimicrobial effect of F. subpinnata EOs after flowering was more than before flowering, in both disk diffiusion and microdilution methods. Hence as a natural and new antimicrobial agent can be substituted with chemical antibiotics, in the pharmaceutical and food industries.

The paper presents an extended implementation of an adaptive filter structure for electrocardiographic (ECG) signals denoising which is implemented on Field Programmable Gate Array (FPGA) circuit. The proposed FPGA adaptive filter structure can be used to clean in real-time the ECG signals from power line interferences. In order to update the adaptive filter weights, the Least Mean Square (LMS) algorithm is used. The discrete forms of the filter structure and adaptive algorithm are presented and argued. The adaptive filter structure and the LMS algorithm were developed on the DE2 platform (Development and Education Board, version 2) which includes an Altera Cyclone II FPGA circuit. The obtained experimental results concludes that the FPGA implementation, designed to process the ECG signals in real-time, presents good performances in suppressing the power line interfering signals.


Alternatively activated macrophages (AAM) differentiate through IL-4/IL-13-mediated activation of Stat6. Microarrays revealed that Stat6 is required for IL-4-induced up-regulation of PD-L2 in murine macrophages. Blockade of PD-L2 prevented the inhibitory activity of AAM against T cells. Retroviral transduction of PD-L2 into Stat6-deficient macrophages was sufficient to inhibit T cell proliferation. These results demonstrate that AAM inhibit T cells by Stat6-dependent expression of PD-L2.

In this paper an alternate numerical approach to evaluate average symbol error probability (ASEP) in log-normal fading channel is proposed. Accuracy of the proposed method is compared with that of existing methods. ASEP of maximal ratio combining (MRC) Rake receiver in Ultrawide band (UWB) multipath channel is evaluated with the help of proposed numerical approach taking a new quadrature based approximate log-normal "power sum" distribution. ASEP of the same is compared with that of obtained using other approximate distributions of log-normal "power sum". It is shown that the proposed method is more general than other methods over both the log-normal and log-normal "power sum" distributed (UWB) channel with comparable accuracy.


Summary Non-stationary analysis is always a challenging task because its frequency content changes as time goes. The S transform is widely used to characterize the time-varying features of a non-stationary signal. However, the resolution of S transform subjects to the Heisenberg Uncertain Principle, resulting in energy diffusion in the time-frequency (TF) plane. To overcome this drawback, we develop a new time-frequency analysis method called synchroextracting S transform (SEST). By employing a synchroextracting operator (SEO) in the S transform, the SEST provides a time-frequency distribution with excellent concentration. Differing from the synchrosqueezing transform (SST) by gathering the time-frequency coefficients near the instantaneous frequency (IF) trajectory, the SEST only retains the coefficients most related to the time-varying features of the analyzed signal. Hence, the SEST produces a sparser time-frequency representation (TFR) with a high resolution while allows for signal construction. We validate the proposed method with synthetic examples and compare the result with existing methods. Then, real data examples also illustrate its effectiveness in delineating more distinct channels in the horizon slices.


With the widespread use of RFID technology and the rapid development of Internet of Things, the research of lightweight block cipher has become one of the hot issues in cryptography research. In recent years, lightweight block ciphers have emerged and are widely used, and their security is also crucial. Skinny-64/192 can be used to protect data security such as the applications of wireless multimedia and wireless sensor networks. In this paper, we use the new method to verify the security of Skinny-64/192. The method is called mixed-integer linear programming (MILP) which can characterize precisely the linear operation and nonlinear operation in a round function. By applying MILP program, we can automatically find a 11-round differential characteristic for Skinny-64/192 with the minimum number of active s-boxes. The probability of differential trail is 2-147, that is, far greater than 2-192 which is the probability of success for an exhaustive search. In addition, comparing this method with the one proposed by Sun et al., we also have a great improvement; that is, no new variables will be added in ShiftRows operation. It can reduce greatly the number of variables and improve the running speed of the computer. Besides, the experimental result proves that Skinny-64/192 is safe on 11-round differential analysis and validates the effectiveness of the MILP method.


The MULATM traffic planning software is now firmly established as a practical tool for local area traffic management. There are now more than 70 users of the package around the world, including Canada, Germany, Indonesia, New Zealand, Singapore and the USA. In January 1989 there were 55 users in Australia, including 28 local government authorities. Many applications of MULATM are now available, and a selection of these are described in this paper. The chosen applications form a spectrum that defines the types of problems to which MULATM can be usefully applied. It also indicates the variety of levels at which users can apply the package. The spectrum of applications reported in the paper ranges from the use of the package as an inventory of the traffic network, through incremental analysis of the effects of local street traffic control devices, simulation of network wide travel conditions and traffic impact analysis to the estimation of environmental impacts. A summary of known applications of MULATM in Australia is provided. The use of MULATM in a wide range of local government applications since 1985 has served to establish the package as an important and useful tool for small area traffic planning and analysis. Each new application contributes something new to the understanding of MULATM and its capabilities and limitations, and continues its evolutionary development. The use of PC based models as "desktop planning" tools is assisting the rapid development of the state of the art in local area traffic management, by accelerating the introduction of new technologies and procedures into engineering practice. In the end, however, the value of such developments should only be judged in terms of their value and use in professional engineering practice. (Author/TRRL)


The aim of this study was to determine the relationships between various forms of physical activities and anthropometric parameters and motor abilities of female students. Measurements took place at the beginning and at the end of the summer semester. It involved 303 first-year full-time female students. The body height, body mass and BMI of participants were determined. Thirteen motor tests were administered to assess motor abilities. The tallest and slimmer students chose martial arts and jogging followed by sauna, whereas the shortest students opted for aerobics and swimming. Students with higher body mass and higher BMI scores were more likely to participate in golf, aerobics, general Physical Education (PE) and swimming classes. Students involved in martial arts, swimming and jogging scored highest in the majority of motor tests. The choice of physical activity (PA) correlated with body height, body mass, BMI and motor fitness. In most motor ability tests, a significant improvement in performance was observed in students who had opted for martial arts, swimming and jogging followed by sauna, which indicates that those activities had the most profound influence on the participants' motor fitness levels.Keywords: Women; Motor performance; Anthropometric features; Forms of physical activity; Physical education


Ocean surface winds and currents play an important role for weather, climate, marine life, ship navigation, oil spill drift and search and rescue. In-situ observations of the ocean are sparse and costly. Satellites provide a useful complement to these observations. Synthetic aperture radar (SAR) is particularly attractive due to its high spatial resolution and its capability to extract both sea surface winds and currents day and night and almost independent of weather. The work in this thesis involves processing of along-track interferometric SAR (ATI-SAR) data, analysis of the backscatter and Doppler frequency shift, and development of wind and current retrieval algorithms. Analysis of the Doppler frequency shift showed a systematic bias. A calibration method was proposed and implemented to correct for this bias. Doppler analysis also showed that the wave contribution to the SAR Doppler centroid often dominates over the current contribution. This wave contribution is estimated using existing theoretical and empirical Doppler models. For wind and current retrieval, two methods were developed and implemented. The first method, called the direct method, consists of retrieval of the wind speed from SAR backscatter using an empirical backscatter model. In order to retrieve the radial current, the retrieved wind speed is used to correct for the wave contribution. The current retrieval was assessed using two different (theoretical and empirical) Doppler models and wind inputs (model and SAR-derived). It was found that the results obtained by combining the Doppler empirical model with the SAR-derived wind speed were more consistent with ocean models. The second method, called Bayesian method, consists of blending the SAR observables (backscatter and Doppler shift) with an atmospheric and an oceanic model to retrieve the total wind and current vector fields. It was shown that this method yields more accurate estimates, i.e. reduces the models biases against in-situ measurements. Moreover, the method introduces small scale features, e.g. fronts and meandering, which are weakly resolved by the models. The correlation between the surface wind vectors and the SAR Doppler shift was demonstrated empirically using the Doppler shift estimated from over 300 TanDEM-X interferograms and ECMWF reanalysis wind vectors. Analysis of polarimetric data showed that theoretical models such as Bragg and composite surface models over-estimate the backscatter polarization ratio and Doppler shift polarization difference. A combination of a theoretical Doppler model and an empirical modulation transfer function was proposed. It was found that this model is more consistent with the analyzed data than the pure theoretical models. The results of this thesis will be useful for integrating SAR retrievals in ocean current products and assimilating SAR observables in the atmospheric, oceanic or coupled models. The results are also relevant for preparation studies of future satellite missions.


A new modulation scheme is proposed to reduce the multiple access interference inherent to frequency hopping networks. The new scheme namely MAFSK is a hybrid of the conventional noncoherent M-ary frequency shift keying and M-ary amplitude shift keying. The hybrid modulation scheme provides significant flexibility to optimize the system BER performance for different operating conditions.

One-third of newly discovered drug molecules are water-insoluble, resulting in poor oral bioavailability in BCS (Biopharmaceutical Classification System). The Self Nanoemulsifying Drug Delivery System (SNEDDS) is a novel drug delivery system designed to improve the water solubility of medications that are ineffectively water soluble. It consists of an isotropic blend of oil, surfactant, and cosurfactant particles, as well as a codissolvable atom. Encapsulating a drug in SNEDDSs can lead to increased solubilization, stability in the gastro-intestinal tract, and absorption, resulting in enhanced bio-availability. The use of solid SNEDDS in the form of dry, solid powders would help to overcome the limitations of liquid SNEDDS by increasing the stability and patient compliance. Solid dosage forms are more stable and easier to handle than liquid systems, so efforts are being made to convert liquid systems to solid SNEDDS. Self-emulsification approach has been successful in oral drug delivery Spray drying, freeze drying, Micro fluidization, High Pressure Homogenizer, Sonication, and adsorption on carriers are some of the techniques that can be used to convert liquid SNEDDS into solid SNEDDS compressed into tablets. The composition of the SNEDDS can be optimized with the help of phase diagrams, whereas statistical experimental design can be used to further optimize SNEDDS. It is a novel drug delivery system that can be used for parenteral, ophthalmic, intranasal, and cosmetic drug delivery.


Conventional water distribution models are formulated under the assumption that water consumption or demand defined at nodes is a known value so that nodal hydraulic head and pipe flows can be determined by solving a set of quasi-linear equations. This formulation is well developed and valid for the scenarios that the hydraulic pressures throughout a system are adequate for delivery the required nodal demand. However, there are some scenarios where nodal pressure is not sufficient for supplying the required demand. These cases may include the planned system maintenances, unplanned pipe outages, power failure at pump stations, and insufficient water supply from water sources. In addition, some water consumptions like leakages are pressure dependent. In this paper, a robust and efficient approach for pressure dependent demand analysis is developed for simulating a variety of low pressure scenarios. A set of element criticality evaluation criteria is also proposed for quantifying the relative importance of the elements that may be out of service. The results are presented for the applications of the approach to the trivial systems and also to a large water system. It is demonstrated that great modeling performance and convergence rates are achieved for modeling pressure dependent demand conditions and evaluating the element criticality of the large water distribution systems.


After becoming independent the relationships between the official powers of Tajikistan and oppo- sition were shaping not easily. The opposition was, in fact, estranged from development and implementation of internal and foreign policy. The results of parliamentary elections conducted in March 2015 did not change the balance of political forces in the Tajik parliament. Moreover, the main opposition party failed to pass into the parliament which led to a new political situation in the country.


Mark-recovery experiments were made to obtain estimates of fishing and natural mortalities as a portion of studies related to the life history of commercial shrimps in the Gulf of Mexico. In two experiments, groups of pink shrimp were injected with biological stains and released into the Sanibel and Tortups fisheries off the southwest coast of Florida. Marked shrimp were recaptured by commercial shrimp fishermen. Mortality estimates were derived from analysis of In the past 3 decades, biologists have probed at various aspects of the life histories of commercial shrimps in the Gulf of Mexico. Recently, largescale, mark-recovery experiments were made to estimate rates of fishing and natural mortalities in shrimp populations. A mark-recovery" experiment, in which biological stains were the marking agent, was undertaken on the Tortugas pink shrimp (Penaeus duorarum) trawling grounds west of Key West, Fla., in September 1961. Development of an appropriate recovery system brought return of 21.1 percent of the marked shrimp. These shrimp were in commercial catches and returned by fishermen at shrimp landing ports. Analysis of data produced estimates of the rate of fishing and natural mortality in the Tortugas pink shrimp population (Kutkuhn, 1966). Two similar experiments were carried out in sou.th Florida waters in 1962 and 1963. Emphasis was placed on obtaining a com"plete tabulation of fishing effort and recovering a high percentage of the marked shrimp that I Contribution No. 229, Bureau of Commercial Fisheries Biological Laboratory, Galveston, Texas 77552. Publlshed March 1968. FISHERY BULLETIN: VOLUME 66, NO. 8 marked shrimp recoveries during the first 10 and 8 weeks of the Sanibel and Tortups experiments, respectively. In the Sanibel population, fishing mortality was estimated to have been 6.8 percent for each 2-week period, and all other losses in the population were 14.8 percent; for the Tortups population, fishing mortality was estimated to have been 13.1 percent for each 2-week period, and all other losses 19.7 percent. were recaptured by commercial gear. One experiment was on the Sanibel grounds south of Sanibel Island, and the other on the Tortugas grounds (fig. 1). These two experiments form the basis of this report. THE SANIBEL AND TORTUGAS FISHERIES In both fisheries, trawling gear is similar to that used elsewhere in the Gulf of Mexico (Bullis, 1951). Trawling is at night because pink shrimp usually remain buried during the da.y. Other species of penaeid shrimp in the catches are of Ininor commercial importance. The area known as the Sanibel grounds comprises about 2,000 km.2 (600 square nautical miles) of trawlable bottom in two sections. south and northwest of Sanibel Island, Fla. Most fishing is on the southern portion of the grounds between the 11and 18-m. depths. The fishery began in 1954 and has produced about 272,000 kg. (600,000 pounds) (tails) of pInk shrimp annually. Peak catches are made from March through May each year when 35 to 90 vessels participate in the

This research identify self-control in online gamers. Whether self-control in online gamers predicted by parenting styles and vision of the future. In this research we identify the online gamers self-control as the ability to guide a gamers behavior using their cognitive and affective process and a decisive action to limit their behavior in playing online games. Participants are online gamers-college students (N=211). From this research we have an information that self-control in online gamers predicted by parenting styles and vision of the future (R2, =0.2870. Moreover, if parents more permissive to their adolescents, more difficult to control themselves in playing online games. Higher level of 'goal' will increase the self-control competencies.


To assess the impact of fertilization on mineral element content in the forage and in blood of grazing Guizhou semi-fine sheep,fertilization and grazing experiments were conducted in the Liangshuiguo pasture area of Weining county.The average concentrations of N in the forages from the fertilized pastures were significantly higher than in those from the control but there were no significant differences between the fertilized pastures.The average concentrations of S,Mn and Zn in forages from the pastures fertilized with ammonium sulfate were significantly higher than those treated with other fertilizers.The application of ammonium sulfate led to a significant reduction in selenium content of the forages.At the end of the study period,the Cu,Fe and Se contents in the blood of Guizhou semi-fine sheep from pastures fertilized with ammonium sulfate were significantly lower than in those fertilized with ammonium nitrate and from the control while the Mn,Zn and S contents were significantly higher.The blood hemoglobin(Hb),packed cell volume(PCV) and serum ceruloplasmin(Cp) contents and the activities of serum SOD,glutathione peroxidase(GSH-PX) and CAT of Guizhou semi-fine sheep from the pastures fertilized with ammonium sulfate were significantly lower than in those fertilized with ammonium nitrate and from the control.Thus,Liangshuiguo pasture area should not be fertilized with ammonium sulfate.


Measurements of drag reduction in two-phase oil-gas slug flow are presented in this study. Two types of oil with markedly different viscosities were examined in 10-cm inner diameter horizontal pipes to evaluate the influence of oil viscosity on the total pressure loss and the effectiveness of drag-reducing agents (DRAs) in reducing the pressure drop in slug flow. The total pressure drop in the 50-cP oil was always more significant than in the 2.5-cP oil, especially when increasing the gas flow rate. However, the DRA was more effective in reducing the total pressure drop in the 2.5-cP oil. Furthermore, increasing liquid velocity, thus increasing liquid volume fraction, resulted in an increase in the DRA effectiveness for both oils.


The article examines the early history of Anna of Kashin and Euthymius of Arkhangelsk's cults. Their veneration began at the end of the 1640s and acquired new content several decades later, after the Russian Church schism. The author of the article focuses on the origin of the legends, according to which the saints rest in their tombs with fingers of their right hands positioned as if they were making a two-finger sign of the cross. The study is based on hagiographic texts dedicated to these saints, legislative acts, documents of church councils, and icons. The author comes to the conclusion that the legends had oral roots and originated among the opponents of Nikon's reforms in the early post-reform period.


In underactuated robots (URs), the motion of the unactuated configuration variable is coupled to that of the others by complex dynamics, which makes their control complicated. Additionally, if the UR is a cable-driven robot (CDR), as cables merely support tensile force, the positiveness of the cable's tension should also be taken into account in controller design. In this paper, we investigate the regulation control of a suspended three degrees of freedom (DOF) CDR using interconnection and damping assignment passivity-based control (IDA-PBC) via potential energy shaping. This method requires analytical solutions to a set of partial differential equations (PDEs). The IDA-PBC approach for the control of the three-DOF CDR results in a complex PDE that cannot be analytically solved using the proposed methods in the literature. To this aim, we transform the governing PDE into a number of Pfaffian differential equations. Then, the resultant Pfaffian equations are solved analytically to obtain the homogeneous solutions of the PDE. Additionally, we have also considered the positiveness of the cables' tension by suitably defining the parameters of the controller. The efficacy of the proposed controller is investigated through simulation, and its performance is compared with a sliding mode control approach.


A second order transition temperature exists for stretched wool fibers in water for the temperature range 60-70° C. This transition is indicated by the transformation in certain physical properties of the fibers such as birefringence and the ability to set per manently. Below the transition temperature a fiber under constant rate of loading passes from the yield to post-yield regions at a value of extension of about 30%, which is independent of the temperature. Above the transition temperature the value of the extension increases with increase of temperature. This variation of the extension at the turnover from the yield to post-yield region with change of temperature above a transition temperature and the constancy of the extension below were shown to hold for chemically and physically modified fibers.


The digital transformation of Chinese construction enterprises is crucial for achieving sustainable and high-quality development in the construction industry. However, there is still a lack of in-depth research on the impact mechanism of digital transformation in construction enterprises. The purpose of this study is to explore the multiple influencing factors and complex causal relationships of digital transformation in construction enterprises and promote the deep integration of digitalization and construction enterprises. To this end, based on the dual-effect perspective (net effect perspective of a single influencing factor and configuration effect perspective of multiple influencing factors), using the "technology–organization–environment" framework (TOE framework) to construct a research model of influencing factors for digital transformation in construction enterprises. A sample of 236 construction enterprise managers was surveyed, and partial least squares structural equation modeling (PLS-SEM) and fuzzy set qualitative comparative analysis (fsQCA) methods were used to empirically analyze the dual effects of influencing factors for digital transformation in construction enterprises. The results show that: (1) from the net effect perspective, there are seven factors that significantly impact digital transformation in construction enterprises; (2) from the configuration effect perspective, there are three paths that can achieve high-level digital transformation in construction enterprises, and one path that leads to low-level digital transformation; (3) from the dual-effect perspective, top management support and policy support are key factors for digital transformation in Chinese construction enterprises. The research results enrich the relevant research on digital transformation in construction enterprises and provide a reference basis for promoting digital transformation in construction enterprises.

The purpose of this study was to analyse and explore the experiences of eight first year physical education teachers who have taught Sudanese refugee students. Interviews were conducted at the end of each participant's first year of teaching. The findings of this study highlight the vast different learning styles of students from Sudan and the strategies that these teacher's trialled and incorporated into their lessons in an attempt to minimise the disruptions that they experienced when first introduced to the students. The results of this study, together with information from the literature, suggest that the training and education of teacher's in Australia must incorporate strategies for teaching students from different backgrounds, cultures and living situations to better facilitate the inclusion of them in school based activities and learning. iafor The International Academic Forum www.iafor.org The Asian Conference on the Social Sciences 2013 Official Conference Proceedings Osaka, Japan


Unstructured data still makes up an important portion of the Web. One key task towards transforming this unstructured data into structured data is named entity recognition. We demo FOX, the Federated knOwledge eXtraction framework, a highly accurate open-source framework that implements RESTful web services for named entity recognition. Our framework achieves a higher F-measure than state-of-the-art named entity recognition frameworks by combining the results of several approaches through ensemble learning. Moreover, it disambiguates and links named entities against DBpedia by relying on the AGDISTIS framework. As a result, FOX provides users with accurately disambiguated and linked named entities in several RDF serialization formats. We demonstrate the different interfaces implemented by FOX within use cases pertaining to extracting entities from news texts.


Basic Properties of Circulant Matrices and Anti-Circular Matrices This article introduces definitions of circulant matrices, line-and column-circulant matrices as well as anti-circular matrices and describes their main properties. MML identifier: MATRIX16, version: 7.9.03 4.108.1028


This article presents the results of studies of the material constitution and physical properties of rocks of foundation of the West Siberian Plate. It is shown that anthraxolite and kerite groups are present in bitumen rocks. We assume that the bitumens create a Late Paleozoic paleo-deposit, transformed under the conditions of apocatagenesis. Impregnation with highly transformed organic matter leads to a significant decrease in electrical resistivity to values of 1–30 Ohm metre, which must be taken into consideration when interpreting low-resistivity zones on log data.


Idea generation is central to many quality improvement methods and techniques but examination of that part of the quality literature which relates to problem‐solving improvement shows a remarkable concentration on just one technique‐brainstorming. Examines the drawbacks of brainstorming and puts forward two further idea‐generation techniques which the author has found particularly useful in the context of quality problem solving.


At 22 wetland localities in SW Sweden, breeding densities of two passerines, Yellow Wagtail and Meadow Pipit, were higher within Lapwing territories than outside them. Earlier studies of predation on artificial nests have shown that the anti-predator aggression of nesting Lapwings results in a reduction of predation on nearby nests. We suggest therefore, that the breeding association of the two passerines and Lapwings is an anti-predator adaptation.


Many electricity distribution companies are installing or have already installed a GIS both as an asset database and as a tool for supporting engineering and other applications. The first part of this paper reviews the current situation using experience gained over several years in installing a program to estimate network reliability indices at United Utilities and other UK distribution companies. The availability of GIS data, providing much more detail of circuit components such as joints, offers the potential to explore more complex models of the network. In the case of network reliability, this should assist in providing a better understanding of the mechanisms of failure and lead to improved models to estimate future performance. These in turn should assist in making more informed investment decisions.


The flow-induced vibration of the microcantilever is investigated. In particular, to avoid flow disturbance resulting from size of measuring probe, we use the monolithic boron-doped piezoresistive microsensors. By characterizing the dynamic behavior of the microcantilever, the new micromechanics is experimentally determined, completely different from the conventional mechanics in the flow-induced vibration.


In 2014, the university reform law N ° 30220 was approved by the Congress of the Republic of Peru; in a convulsed context of opposition to the new supra-institutional parameters, which the university power groups believed, violated their autonomy. The Villarrealino student movement, with its limitations and tensions, assumed leadership in the capital during this period. Under a structure of liberalization of the educational market and demobilization inherited from the nineties, we ask ourselves: what scope and limitations did the collective action of the student movement in Villarreal present during the years 2013 to 2016? The objective of this article then will be to approximate and determine it. For this work we apply participant research and retrospective systematization of the facts as research methods; in order to reconstruct the experience and guide interventions of the movement. For this we have analyzed written and oral sources of the students and graduates involved. On the other hand, this is an essay to analyze the nuances between the various theoretical approaches of social movements, as eventually contradictory paths, applied to this case and focused on immersing oneself in the political subjectivity of those who seek change. This process of gradual conquests of the students should serve to redirect their efforts towards the university government with the same tenacity that they have destined for the grassroots organization with the ultimate aim of breaking the hegemony of the hidden party interests made visible in times of crisis; promoting legislative initiatives and providing them with mechanisms of greater democratic scope.


The blood-brain barrier (BBB) blocks most compounds from entering the central nervous system (CNS), limiting the success rate of new treatments of CNS disease. Insight needed to overcome these limitations can be gained through innovation of more representative models of the BBB. We present the first multi-layered microfluidic device (MMD) for dynamic modeling of the BBB. Brain endothelial cell monolayers cultured in the device exhibited the following BBB properties: Tight junction formation as indicated by immunostaining, trans-endothelial electrical resistance (TEER) values of over 250Ωcm 2 by day 3 of culture, and size-selective permeability of a range of test permeates.


This paper examines why an electric ship is so desirable to a naval architect. A naval architect appreciates arrangeable volume, arrangeable equipment, large cargo capacity, large endurance, low thermal management, lots of bulkheads, few hull penetrations, equipment that is flexible and has multi-uses. Naval architects also need equipment that is reliable, available, and maintainable to reduce impacts to required ship accesses and personnel required to do maintenance. The fundamental characteristic of electric propulsion is an enabling topology that matches well to the needs of the naval architect.

【Objective】 The purpose of the present research was to explore the differences in metabolism and transcripts between porcine subcutaneous and visceral adipose tissues.【Method】 A phenotype analysis and a comprehensive transcriptome analysis by high-throughput RNA-Seq was carried out in three porcine adipose tissues,including one subcutaneous adipose tissue(backfat) and two visceral adipose tissues(greater omentum and mesenteric adipose tissue).【Results】 Visceral adipose tissues had smaller adipocyte volume and showed significantly higher content of Saturated Fatty Acid(P0.01) but lower content of Unsaturated Fatty Acids(P0.05) than subcutaneous adipose tissue,meanwhile,we obtained 30 532 913-33 479 707 unique mapped reads that covered 80.2% of the current annotated transcripts and identified 4 583-4 765 novel transcript units,and further identified 936-1 029 splicing genes,16 559 SNPs and 1 481 INDELs.We also identified 183 genes that differently expressed between the subcutaneous and visceral adipose tissues,which were mainly associated with the biological categories of the unsaturated fatty acid biosynthetic,carboxylic acidmetabolic and inflammatory response.【Conclusion】 This study provided a global view of transcriptome in porcine adipose tissues,and the differential gene expression analysis showed some potential genes that could partly revel the function characteristics and differences between these two types of adipose tissue.


We investigate the collective motion of rotlets that are placed in a single plane. Due to the hydrodynamic interactions, the particles move through the two-dimensional (2D) plane and we analyze these diffusive motions. By analyzing the scaling of the values, we predict that the diffusion coefficient scales with ϕ0.5, the average velocity with ϕ, and relaxation time of the velocity autocorrelation function with ϕ–1.5, where ϕ is the area fraction of the particles. In this paper, we find that the predicted scaling could be seen only when the initial particle position is homogeneous. The particle collective motions are different by starting the simulation from random initial positions, and the diffusion coefficient is the largest at a minimum volume fraction of our parameter range, ϕ = 0.05. The deviations based on two initial positions can be explained by the frequency of the collision events. The particles collide during their movements and the inter-particle distances gradually increase. When the area fraction is large, the particles will result in relatively homogeneous configurations regardless of the initial positions because of many collision events. When the area fraction is small (ϕ < 0.25), on the other hand, two initial positions would fall into different local solutions because the rare collision events would not modify the inter-particle distances drastically. By starting from the homogeneous initial positions, the particles show the maximum diffusion coefficient at ϕ ≈ 0.20. The diffusion coefficient starts to decrease from this area fraction because the particles start to collide and hinder each other from a critical fraction ∼ 23 %. We believe our current work contributes to a basic understanding of the collective motion of rotating units.


Endometrial and ovarian synchronous cancer (SEOC) accounts for about 5-10% of endometrial and ovarian neoplasms. When there is no local extension and they present a low-grade histological pattern, they act as if they were two independent primary tumours, instead of behaving as an advanced stage cancer. Therefore, the differentiation of its origin (metastatic or independent primary tumours) is fraught with difficulty and has generated a significant controversy in the study of this type of neoplasms. In this article, we present the clinical case of a 46-year-old patient presenting a synchronous tumor of the endometrium and ovary in IA stage, unknown until the histological study of the surgical sample.
