Suppression of gas entrainment (GE) phenomena caused by free surface vortices are very important to establish an economically superior design of the sodium-cooled fast reactor in Japan (JSFR). However, due to the non-linearity and/or locality of the GE phenomena, it is not easy to evaluate the occurrences of the GE phenomena accurately. In other words, the onset condition of the GE phenomena in the JSFR is not predicted easily based on scaled-model and/or partial-model experiments. Therefore, the authors are developing a CFD-based evaluation method in which the non-linearity and locality of the GE phenomena can be considered. In the evaluation method, macroscopic vortex parameters, e.g. circulation, are determined by three-dimensional CFD and then, GE-related parameters, e.g. gas core (GC) length, are calculated by using the Burgers vortex model. This procedure is efficient to evaluate the GE phenomena in the JSFR. However, it is well known that the Burgers vortex model tends to overestimate the GC length due to the lack of considerations on some physical mechanisms. Therefore, in this study, the authors develop a turbulent vortex model to evaluate the GE phenomena more accurately. Then, the improved GE evaluation method with the turbulent viscosity model is validated by analyzing the GC lengths observed in a simple experiment. The evaluation results show that the GC lengths analyzed by the improved method are shorter in comparison to the original method, and give better agreement with the experimental data.


The literature of inventory contains many examples of order quantities chosen so as to achieve some fixed probability of stockout in the period following the order's arrival. This note shows, for independent normally distributed demands, n-period delivery lag, and lost sales, how the computation of such an order quantity can be reduced to cumulative operations on a standardized (n + 1)-dimensional normal distribution.


We present our experiments on integrating and evaluating distributional semantics with the recognising textual entailment task (RTE). We consider entailment as semantic similarity between text and hypothesis coupled with additional heuristic, which can be either selecting the top scoring hypothesis or a pre-defined threshold. We show that a distributional model is particularly good at detecting entailment related to "world knowledge", and that aligning the hypothesis with the text improves detection of lexical


Multipath effects usually occur in information dissemination, which leads to inter-symbol interference and affects the quality of communication transmission. This paper uses an adaptive equalizer to achieve channel equalization and eliminate inter symbol interference, and develops and verifies it on the FPGA using the ISE suite. Compared with the equalizer output error signal calculated on the MATLAB software, the calculation results of the two platforms are basically the same, which confirms that the design is feasible. The FPGA-designed equalizer implements hardware acceleration and is more suitable for high-speed real-time signal processing. After the data passes through the adaptive bit equalizer, the signal-to-noise ratio is improved, thereby reducing the bit error rate and verifying the relationship between the bit error rate and the signal-to-noise ratio.

Interaction of pulses in optical fibers is analyzed by solving the scattering problem associated with the nonlinear Schrodinger equation. It is shown that two pulses without initial phase modulation can generate moving daughter solitons. © 2002 Optical Society of America OCIS codes: (060.4370) Nonlinear optics, fibers; (190.5530) Pulse propagation and solitons Interaction of solitons in optical fibers results in a variation of a separation distance and even in a formation of additional solitons with small amplitudes ("daughter pulses"). Both these factors constrict the repetition rate, which is an important characteristics of optical communication systems. We consider the influence of different initial parameters to the soliton interaction. We show that nonlin ear interference between pulses results in non-trivial dynamics. For example, depending on the separation distance, two pulses without initial phase modulation can generate a number of moving solitons. It is also shown that the relative constant phase is also important for the interaction dynamics.


We report the vibrational properties of lithium-intercalated SnSySe2_y (0~_y<_2) layered compounds. Infrared absorption spectra have been recorded as a function of temperature in the frequency range 50-600 cm -t. The new bands are interpreted as vibrational modes of lithium atoms against the nearest-neighbouring-chalcogen atoms located in the van der Waals gap. Results are analyzed in terms of stretching vibrations of Li-S 4 and Li-S 6 entities. From a comparison of the spectra, it is concluded that lithium ions are more likely to occupy tetrahedral sites in the lithiumrich phases. Using a simple model of lattice dynamics, the coupling force constants are determined and compared with those of the pristine materials.


The use of wireless technologies within factories demands a comprehensive understanding of the problems and potential solutions associated with the rigors of the manufacturing environment. A clearly defined problem space would significantly ease the selection and deployment of appropriate wireless solutions to connected factory systems. A mapping of potential technologies to classes of use cases within the problem space will be useful to factory operators, system integrators, and wireless systems manufacturers. Identification of use cases, not addressed by existing technologies, may be used to spur targeted innovation where reliability, resilience, latency, and scalability are joint concerns. Motivated by the industry need for independent practical guidelines and solutions to difficult wireless control problems, this paper provides a classification of the problem categories where networking technologies may be deployed. It then maps specific technologies that may serve as interim or terminal solutions for those use cases identified within the problem space taxonomy.

The large amount of rice produced in Brazil generates a large volume of co-products, such as, Rice Husk (RH) and Rice Husk Ash (RHA). These co-products have amounts of silicon (Si) present in their structure, which can be used to synthesize silica-based materials as zeolites and MCM-type structures. The synthesis of MCM-48 material was carried out at room temperature, using the ionic liquid [C16MI·Cl] as structure-directing agent, depositing the niobium in situ during the synthesis with different molar ratios of Si/Nb (5, 20, 50 and 80). The material obtained was subjected to characterization by X-Ray Diffraction (XRD), Nitrogen Adsorption/Desorption isotherms and Scanning Electron Microscopy (SEM). The results confirm the formation of Nb/MCM-48 materials, in which their properties are consistent with those described in the literature. The deposition of Nb on MCM-48 did not change its structural properties, such as specific surface area and pore distribution for Si/Nb higher than 5. The results obtained demonstrate the success in the synthesis of mesoporous materials Nb/MCM-48 using industrial residues of rice as an alternative source of silicon, and in situ deposition of the niobium metal on the structure.


The EPA is preparing to issue new regulations calling for enhanced monitoring of ozone and oxides of nitrogen and additional monitoring of volatile organic compounds (VOC), including aldehydes, as well as meteorological parameters. Ozone non-attainment areas classed as serious or worse would be required to establish photochemical assessment monitoring stations (PAMS). Long path, remote sensing methods are not deemed by the EPA to be sufficiently accurate and comprehensive in providing fully speciated VOC measurements to be included in the regulations. This paper reports on the performance of a representative long path system based on ultra-violet absorption spectroscopy, and assesses the potential benefits and limitations for the future use of such systems in the PAMS network and in related air quality management applications. The basis for our assessment is field experience with a commercially available U-V spectroscopic long path instrument, using differential optical absorption spectroscopy (DOAS), as well as reference to the published experience of others using similar long path methods for measuring air pollutants. The database for our analysis consists of air quality measurements, obtained from the DOAS instrument and an existing network of point monitors (as archived in the AIRS database of EPA), in the Washington DC region during the summer of 1991. The goal of this continuing study is to suggest ways in which the long path spectroscopic methods might be used in a cost-effective manner to complement the more detailed batch sampling methods in support of urban air quality management.


Using interview data collected from high school students who attended school in Broward County, Florida, this article focuses on how first- and second-generation adolescent Latinas understand citizenship. The author explores participants' citizenship formations using the conceptual frameworks of transnationalism and cultural dimensions of citizenship. Drawing richly from their voices, the author sheds light on the paradoxes of citizenship and national belonging by illuminating how Latina youth are positioned as ambiguous U.S. residents and citizens. She concludes with an exploration of the practical implications of attending to youths' re-articulations of citizenship and national belonging.


Ukraine Abstract. The article covers all the stages of the process of fire protection: as the separation of gases, heat transfer, the swelling of the coating, which is formed during by the action of fire. To determine the fire protection efficiency in the coatings developed, studies have been carried out on determining the combustibility of wood in terms of mass loss and increase in the temperature of flue gases, and it has been established that mass loss of coated wood does not exceed 3% and the temperature does not exceed 160°C. The results of the determination of the protection efficiency for the system have shown that under the influence of the high-temperature flame of burning of the material and the loss of the mass of the coating is reduced due to the formation of high-temperature compounds, while the time to reach the limiting temperature increases. Studies on determining the quality of fire protection wood treatment by coating showed that the rate of cooking for a rough sample of wood was more than 2 mm/min, for fire-proof samples - did not exceed 0.5 mm/min, which makes it possible to conclude that it is advisable to use


The concern with the action of chemical dyes in human health is not only in Brazil, but throughout the world. One reason for the alert is due to recent results in European research related to the actions of dyes in baby foods, for example. However, the question of the risk of dyes has never been studied properly because of the assumption that these were harmless components. Several industries as pharmaceutical, cosmetic, printing and textile have widely used azo dyes. The textile industry is a substantial consumer of water and produces enormous volumes of contaminated water; the most important contaminants are azo dyes. The discharge of highly colored effluents affects water transparency, gas solubility in water bodies and may induce several human pathologies (carcinogenicity and toxicity). Therefore, new technologies using fungi to removal of such dyes before discharging them into environment is essential, mainly when related to human health.

Crocodylus niloticus is found in 26 African countries including Ethiopia, the largest recorded specimen measuring 17.0 feet Nile crocodile from the Gambela Upeno River in 1969. Its presence and absence also depend on the climatic conditions and the environment (i.e. the landscape for basking and feeding). In Ethiopia, Nile crocodiles have a mating period during September to October, Nesting occurs in the dry season December to January, and hatchling takes place at the onset of the rainy season, i.e. March/April months. Over the period of 2007-2016 an average of 201,000 Crocodylus niloticus skins were exported globally per year, with an increasing trend over the period 2009-2016. Besides the management problems, at Arba Minch Crocodile Ranch, Nile crocodiles are suffering from nutritional abnormalities and health problems. The diseases of the Nile crocodile are classified as infectious (transmissible) and non-infectious (non-transmissible). A transmissible crocodile disease includes bacterial, viral, fungal, protozoan, and parasitic diseases; non-transmissible crocodile diseases are nutritional, toxic poisonings and metabolic disorders; other diseases like nutritional bone diseases and skin lesions are the major health problems at Arba Minch Crocodile Ranch. The main aim of this review is to highlight the major diseases and management status of Crocodylus niloticus in Arba Minch ranches, Ethiopia. In conclusion, the Arba Minch Crocodile Ranch (AMCR) should exercise care and caution when introducing hatchlings from the wild into the Ranch and enhance its husbandry methods to reduce the occurrence of infection and disease. It must also work with professionals and research groups.


The microstructure and mechanical properties of the as-cast Zn-25Al-5Mg-2.5Si-xGd alloys at room and elevated temperature have been investigated in this work. The results show that the addition of element Gd leads to the grain refining and the formation of Al3Gd phase and GdZn12 phase in the microstructure, and the mechanical properties of the alloys rise at first and then drop with the Gd content increasing. When Gd content is 0.8wt.%, the optimization of microstructure and mechanical properties is obtained. The alloy can be increased by 13.9%, 37.7% and 45.6% in tensile strength and be increased by 13.4%, 76.9% and 78.2% in hardness at room temperature, 100°C and 180°C, respectively.


The halictid bee Halictus ligatus ranges from southern Canada to Colombia and Trinidad. In cool, temperate regions it develops small, summer, eusocial colonies similar to those of many halictids and consisting of a queen and several workers which are usually unmated and which lay few if any eggs. These colonies collapse in late summer or autumn, when the old queen and workers die; only new young queens survive the winter. In the tropics and probably also in Florida and elsewhere in the warm temperate regions, while such eusocial colonies may occur as an ontogenetic stage, the colonies become larger and presumably consist of daughters or more remote descendants of the foundress. They are active through all or most of the year and all adult females appear capable of surviving unfavorable seasons. \Vhile some of the bees are old foragers, unmated, with slender ovaries, i.e., workers, over half are mated, egg-laying foragers. Most of the eggs are laid by such foragers and in most colonies in these warmer regions there is no evidence of non foraging reproductives , i.e., queens. The social structure in the tropics does not correspond to any of the named types of social organizations. There is a continuum in size with no bimodality from the smallest to the largest females. In temperate regions large individuals are produced primarily in late summer and are the young gynes which will overwinter. In the tropics , large individuals are produced at all seasons when there is reproduction. At least some large indi viduals are produced in large cells with elongate food masses. Other geographically-varying, biological features are as follows: From Florida southward, males seem to be produced in any months when females are produced. In cool temperate regions, perh aps with the exception of the northernmost population studied (Ontario), males are produced principally in late summer; early summer prog eny are nearly all females. Northern populations usually make shallow nests which are of ten aggregated. From Kansas , southward, nests are commonly deep and rarely aggregated. N est guardin g is comm on in cool, temperate reg ions, rare in the tropics.


Objective: To evaluate the "in vitro" antibacterial effect of the ethanolic extract of the seed of Persea americana (avocado) on Enterococcus faecalis ATCC29212.

Materials and methods: The antibacterial effect was determined by susceptibility testing using the Kirby-Bauer method. 23 repetitions were performed for each treatment (ethanolic extract of avocado seed at different concentrations and for the control group chlorhexidine 2%). The strains of Enterococcus faecalis were seeded in plates containing culture medium Mueller Hinton, and placed disks with different concentrations of ethanolic extract of avocado seed, then the plaques were incubated at 37 °C, measuring halos with a millimeter ruler after 24 hours.
Minimum Inhibitory Concentration of ethanolic extract of avocado seed was also determined using the dilution method in tubes, to which the inoculum of Enterococcus faecalis was added and taken into the oven at 37 ° C for 24 hours, then planted in plates for observation of bacterial growth in the form of colony forming units (UFC).

Results: The averages of growth inhibitory zone founded were: 11.2; 13.09; 15.35; 19.35 mm, corresponding to concentrations 10%, 25%, 50% and 75% respectively. Statistical analysis of the data revealed highly significant statistical difference between groups (ANOVA: P <0.01). The average colony forming units for the group of 10% concentration was 2.67×101UF and for groups concentrations 25%, 50% and 75% was 0 UFC.

Conclusion: The ethanolic extract of Persea americana seed at different concentrations, has antibacterial effect "in vitro" on Enterococcus faecalis,
Minimum Inhibitory Concentration being the 25%.


The mobile humanoid Rollin'Justin is a versatile experimental platform for research in manipulation tasks. Previously, different state of the art control methods and first autonomous task execution scenarios have been demonstrated. In this video two new applications with challenging task requirements are presented. One is the catching of one or even two flying balls using all of Justin's degrees of freedom. The other is the autonomous preparation of coffee. Both applications need adequate sensors to support local referencing. The required precision in position and timing is realized in software, using the sensor information, taking the varying precision of Justin's kinematic sub-chains into account and handling all timings in sub-millisecond range.


[Abstract] Fluoro-Jade is a fluorescent derivative used for histological staining of degenerating neurons. This technique is simple and sensitive enough to label distal dendrites, axons, axon terminals as well as neuronal bodies. Fluoro-Jade has excitation and emission peak of 480 and 525 nanometer respectively. It can be visualized using a fluorescein/FITC filter. Some reports have demonstrated that Fluoro-Jade can also be useful to detect glial cell death (Anderson et al., 2013; Damjanac et al., 2007).


In this paper contains some remarks regarding projectively related (metric) connections on a 4-dimensional manifold, that is, Levi- Civita connections which yield the same paths for their (unparametrised) geodesics. Some techniques for such an investigation are brie∞y outlined. The signature of the metric is arbitrary but special emphasis is laid on the Lorentz case and the connection with the Einstein principle of equivalence in general relativity theory. The results are based on joint work with David Lonie and Zhixiang Wang in Aberdeen.


In the past 15 years microsimulation software tools have increased the ability to analyze congested traffic by modeling at the level of individual vehicles. Although this can be very detailed, it assumes that mode choice is fixed. The research presented models the people in the network, either walking or in vehicles, following each person for an entire trip through multiple modes of travel. This approach is called "nanosimulation." The paper presents a pilot project that analyzes access to an airport by comparing multiple parking options, rail transit, drop-off, and taxi access. Generalized cost incorporating time, distance, and price is visualized for each access method and allows comparison of the total end-to-end cost of all combinations of modes in an interactive three-dimensional simulation model. The primary objective of the research presented is to prove that analysis at this level is practical and can provide insight that is not available from other methods. A historical perspective of microsimulation is presented to illustrate how seemingly impractical models that were run on a supercomputer in 1994 are now in common use on sub-$1,000 everyday computers. The paper describes the technologies, data structure, and algorithms used in the research and addresses the issues of data availability and model repeatability. The model area is described, with illustrations of the visualization. The final sections present results of the project, followed by conclusions and recommendations.


Abstract Logistics planning and management are integral to the successful management of construction projects. Although on-site logistics are critical to efficient project delivery, they receive less attention in terms of research. This research introduces a new method for planning on-site logistics operations utilizing vertical supply systems (VSS) in high-rise projects. This method challenges the limitations of using critical path method and Resource Constrained Project Scheduling Problem in scheduling high-rise projects. The presented method treats lifting operations as activities with durations. The method presents a new classification of lifting activities based on their relation to other works, and it prioritizes the assignment of VSS to lifting activities based on the flexibility of VSS choice for each task. These two novel contributions allow planning construction works to match the capacity of available VSS, and it allows an efficient distribution of lifting tasks among available VSS. This method was applied to two towers in an ongoing project. The application to the first tower was during construction which allowed measuring tangible improvements on site and the other applied during the planning stage. The application of this method resulted in shorter floor cycles by 20% to 30%, less idle workers and more efficient cost control.


The scale and complexity of computer-based safety critical systems pose significant challenges in the safety analysis of such systems. In this chapter, the authors discuss two approaches that define the state of the art in this area: failure logic modelling and behavioural modelling safety analyses. They also focus on Hierarchically Performed Hazard Origin and Propagation Studies (HiP-HOPS)—one of the advanced failure logic modelling approaches—and discuss its scientific and practical contributions. These include a language for specification of inheritable and reusable component failure patterns, a temporal logic that enables assessment of sequences of faults in safety analysis as well as algorithms for top-down allocation of safety requirements to components during design, bottom-up verification via automatic synthesis of Fault Trees and Failure Modes and Effects Analyses, and dependability versus cost optimisation of systems via automatic model transformations. The authors summarise these contributions and discuss strengths and limitations in relation to the state of the art.


Copyright© Taylor & Francis 2007. ISSN 1745–3674. Printed in Sweden – all rights reserved. DOI 10.1080/17453670710014446 A 47-year-old woman presented with pain in the left groin lasting 4 months, without any trauma. A solitary osteochondroma of the proximal left femur had been diagnosed radiographically 19 years earlier (Figure 1). A hard, tender mass could be palpated in the proximal medial part of the left thigh. The mass was fixed to the bone, but the overlying skin was mobile. No enlarged lymph nodes were palpable in the left groin. There was no neurovascular compromise of the left lower limb and the laboratory tests were unremarkable. Plain radiographs of the left hip showed a changed appearance of the exostosis compared to 19 years earlier. There was an extensive ossified mass with multiple peripheral calcifications (Figure 2). A Technetium-99m HDP bone scan revealed increased uptake at the site of the osteochondroma. MRI showed continuity of the osteochondroma with the lesser trochanter; it was unclear whether there was a continuity between the exostosis and the overlying mass. It was difficult to assess the thickness of the cartilage cap. There was a clear demarcation between the cartilage and the adjacent soft tissues that were not involved (Figure 3). The differential diagnosis included peripheral chondrosarcoma and secondary synovial chondromatosis (SC). CT confirmed cortical and medullary continuity of the exostosis with the underlying bone,


The demands and interests in non-contact health monitoring have increased rapidly in recent years due to its noninvasive method and easy to use in daily life. In this paper, a real time and non-contact based cardiac monitoring system including a sensor is presented. The sensor is capacitively-coupled with human skin and does not cause impediments in the natural movement of the user. Moreover, low power RF module nRF24L01+ and passive components were used for reducing power consumption. Current monitoring systems for premature infants are not convenient due to the usage of patched or adhesive tape for monitoring vital information. The front end circuit is integrated with multiple stages of amplifier, filters, analog to digital converter and the wireless module. The non-contact capacitive electrode was integrated into the leather belt as well as in the chair to monitor electrocardiography (ECG) signals. In this work, a simple and easily accessible ECG monitoring sensor node for body area networks was designed and tested. The proposed system was compared through experiments with the one with Ag/Agcl based electrodes. The results show that the proposed system could accurately be used as a medical grade equipment for long-term health monitoring.


Materials for potential use in tokamak first wall high current connectors were selected and tested under conditions that might be encountered in tokamak devices. Disk-shaped specimens of promising metal mixtures were subjected to current densities approaching 23 kA/cm/sup 2/ (150 kA/in/sup 2/) in 8 ms pulses, closing pressures ranging from .07 to 2.1 MPa (10 to 300 psi), and a vacuum of 1.3 X 10/sup -1/ Pa (10/sup -3/ Torr). Contact welding occurred at moderate to low pressure and moderate currents. The resulting welds were very weak, failing at 18-31 N (4-7 lb) in shear.


A comparison of the architectural models applied, on the one hand, at the papal residence in Avignon (Benedict XII) and the royal and imperial residences in Bohemia (Charles IV) and, on the other, at the first forms of baronial apartment consisting of public (sala regia) and private rooms (studiolo; thalamus, locus) offers a new way of approaching this aspect of architectural history. The baronial apartment was a specific type of room in the residence and an early sign of the gradual transformation of the fortress architecture that had been associated with itinerant rule. Accordingly, it should be interpreted as one of the first example of the 'state-building' architecture used to construct fixed or temporary residential locations.

Objective To explore the effects ofα-enolase-targeted RNAi on the energy metabolism and contractility of myocardial cells.Methods Three chemically synthesized specific siRNAs targeting toα-enolase were transfected into cardiomyocytes,the mRNA and protein expression ofα-enolase were detected by real-time RT-PCR and Western blot.Cardiomyocytes were divided into control group and RNA interference group.One of the highest effective siRNA(target site 406—425 ofα-enolase mRNA) was selected and transfected into RNA interference group.Intracellular ATP level was measured by the luciferin-luciferase assay and the contractile responses were analyzed using the video tracking system.Contractile parameters included contractile amplitude(dL) and peak velocity of cell shorting(dL/dt_(max)).Results The mRNA and protein expression ofα-enolase were downregulated markedly by Sequence 1 siRNA in dose and time dependent manners,with 200 nmol/L of which achieved the highest knock down effect on mRNA at 24 h and on protein at 48 h after transfection.Compared with control group,at 48 h following transfection,both intracellular ATP levels(RNAi:3.55×10~(-7)vs control:6.08×10~(-7) nmol/mg protein, P0.05) and magnitude velocity of contractility[(magnitude of contractility,RNAi:0.82±0.02μm vs control; 1.48±0.12μm,P0.01),and velocity of contractility(velocity of contractility,RNAi;2.7±0.3μm/s vs control:6.75±0.16μm/s,P0.01)]in cardiomyocytes in RNA interference group were decreased.Conclusion Expression ofα-enolase in cardiomyocytes was effectively knock down by siRNA with target site 406-425 ofα-enolase mRNA,α-enolase-targeted RNAi leads to the suppression of ATP production and the decreasing of contractility in cardiomyocytes.


This paper provides an overview of the various properties of engineered cementitious composites (ECCs) that are used in a variety of structural applications. Different properties of engineered cementitious composites are investigated in this paper, including tensile, flexural, compressive, tensile strain capacity, shear strength, toughness, fibre matrix interaction, drying shrinkage, water permeability, sorptivity, cracking, impact and frost resistance, and beam-column connection behavior. According to the study, ECC has a much greater strain capacity than conventional concrete, as well as a higher energy absorption capacity, defection capacity, and impact resistance, as well as a crack width of less than 100 m. The use of mineral admixtures improves tensile strain capacity with multiple fine cracks, while compressive strength and carbon dioxide emissions decrease, according to the findings of various studies. Fiber hybridization can increase ECC's strain hardening with various fine cracking, flexural and toughness properties, impact resistance, and crack width resistance.

Comparing with the classical local gradient flow and phase field models, the nonlocal models such as nonlocal Cahn–Hilliard equations equipped with nonlocal diffusion operator can describe more practical phenomena for modeling phase transitions. In this paper, we construct an accurate and efficient scalar auxiliary variable approach for the nonlocal Cahn–Hilliard equation with general nonlinear potential. The first contribution is that we have proved the unconditional energy stability for nonlocal Cahn–Hilliard model and its semi‐discrete schemes carefully and rigorously. Second, what we need to focus on is that the nonlocality of the nonlocal diffusion term will lead the stiffness matrix to be almost full matrix which generates huge computational work and memory requirement. For spatial discretizaion by finite difference method, we find that the discretizaition for nonlocal operator will lead to a block‐Toeplitz–Toeplitz‐block matrix by applying four transformation operators. Based on this special structure, we present a fast procedure to reduce the computational work and memory requirement. Finally, several numerical simulations are demonstrated to verify the accuracy and efficiency of our proposed schemes.


This paper is aimed to review significant development in the design and analysis of smart meter based on different technologies. India is the 5 th largest producer and consumer of electricity in the world. The utility electricity sector in India had total installed capacity of 288 GW as on 31 January 2016, and up to 2024 this will be 603 GW. This target will not be achieved only by installing new power plants, but there must be necessary ways to reduce losses in transmission and distribution side. Energy conservation and energy audit are helpful in reducing electrical losses. Smart metering is useful for electricity management, dominating power shortages, preventing theft, etc. This paper proposes how the new smart meters can be used for efficient power distribution and load management.

Thank you for downloading simulations and the future of learning an innovative and perhaps revolutionary approach to e learning. Maybe you have knowledge that, people have look numerous times for their chosen books like this simulations and the future of learning an innovative and perhaps revolutionary approach to e learning, but end up in harmful downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they juggled with some malicious bugs inside their laptop.


Method for identifying an allele by detecting polymorphisms comprises: (a) preparing single-stranded nucleic acid molecules corresponding in sequence to the portion of the allele containing the target polymorphisms; (b) labelling the single-stranded nucleic acid molecules; immobilising oligonucleotide probes, each specific for a known polymorphism, on a support; and (c) detecting fully complementary duplexes formed between the labelled single-stranded nucleic acid molecules and the immobilised probes.


This paper deals with the degradation behaviour of randomly oriented continuous glass-fibre mat reinforced polypropylene (glass/PP) immersed in hot water. The weight changes and the bending properties were measured after immersion in water, and these were compared with the data for glass fibre reinforced unsaturated polyester (glass/UP). The weight changes of glass/PP were much less than those of glass/UP, and the fibre/matrix interface of glass/PP maintained its effective bonding even after immersion. As a result, the reduction in bending modulus of glass/PP was very slight. The bending strength of glass/PP decreased linearly against the net weight gain and the weight loss. The relationship between the bending strength and the weight loss was almost the same, independent of the materials used. It is suggested that the strength reduction in glass reinforced polypropylene was induced by the formation of microcracks, which also caused the weight loss.


Abstract : The steady state cortical evoked response shows enhanced amplitude to a visual stimulus which is flickered in the frequency range between 38 Hz and 66 Hz. In this study, amplitude was found to be greatest at one particular frequency of stimulation, with the magnitude of the response to the peak frequency as much as double the amplitude of the surrounding frequencies. While all subjects demonstrated this enhancement, the particular frequency at which it was found varied from subject to subject. The range of peak frequencies was found to be 50 Hz to 56 Hz for the subjects studied. Sine wave modulated light produced this effect, while stroboscopic stimuli in the same frequency range did not produce it as clearly. It is hypothesized that this narrowly tuned response may be related to a subject's performance, as well as to other physiological characteristics of the individual. Since this amplitude increase is narrowly tuned, it is suggested that the advantages and disadvantages of stimulating humans at their peak frequency should be determined. Possible uses of this phenomena for studying brain functioning and behavior are discussed.


The sulfolobus, a thermophilic microorganism, can grow at high temperature up to 65?℃. It has good ability to oxidizing element sulfur and ferrous ion and can meet the high temperature demand in dump leaching and chalcopyrite stirring leaching in a reactor. The culture results show that at 75?℃ the sulfolobus has more adapted to the environment than below and above the temperature. The changing tends of the solution pH, redox potential, SO~ 2- _4 concentration and ferrous oxidation rate with time in bio culture as well as in bioleaching of chalcopyrite concentrate were elucidated. The bioleaching experiments show that using the trained sulfolobus strains at 75?℃ in the shake blasting when the slurry mass fraction is below 10%, the chalcopyrite concentrate leaching rate could up to 90% after 150?h leaching. But when slurry mass fraction is up to 15%, after 350?h leaching, the leaching rate is only 80%. It demonstrates that the slurry mass fraction has apparently effect on the leaching results.


In the early morning hours of October 26, Medic and Engine 205 were dispatched for a report of a brick wall collapse that had trapped a 21 year-old victim. When they arrived on scene, Medic and Engine 205 discovered an intoxicated man lying on the ground a few feet away from a pile of debris and bricks. He said that he had been chasing a cat when he tried to climb the wall and it had collapsed. The victim was alert and oriented with abrasions to his arms, knees and chest. He didn't have any clear signs of severe injury, but was complaining that it hurt when he tried to take a deep breath. Instead of dismissing the patient as drunk or assuming his lack of obvious injuries meant he wasn't hurt, Medic Kohrt and his partner, Medic Remi Howell, performed a full trauma assessment. They decided to transport the patient to George Washington University Medical Center, instead of the closer Inova Alexandria Hospital, which is not a Level 1 Trauma Center. Upon arrival, the trauma team was not initially sure the victim needed to be there. That changed once they saw the results of a CT scan. The scan showed the patient had a severe laceration on his liver and was bleeding into his abdomen. He was rushed to the operating room where he received several units of blood and his liver was repaired. The medics' decision to drive a few extra miles and take some extra time with this victim while nearing the end of a 24-hour shift may have saved his life. The head of the Trauma Department for George Washington University Medical center called the case nothing short of remarkable adding, "The teamwork that it took to keep this kid alive (starting with EMS) is the reason that he is alive."


1025 Background: 10–44% of patients with OPLs will be diagnosed with squamous cell carcinomas of the head and neck (SCCHNs) over 5–10 years. Cyclooxygenase-2 (COX-2) is progressively upregulated in SCCHN tumorigenesis, and is associated with the malignant phenotype. Preclinical data shows that COX-2 inhibition suppresses tumorigenesis. Methods: This phase II study investigated effects of celecoxib on surrogate endpoint biomarkers (SEBs) in 20 patients with OPLs. Oral mucosa prostaglandin E2 (PGE2) levels in post- vs. pre-treatment samples is the primary SEB. Other SEBs include Ki67, microvessel density and histology. Eligibility requirements included OPL, no tobacco for ≥ 1 month, and no contraindication to celecoxib. Pre- and post-treatment biopsies after 3 months (mos) of celecoxib (400 mg BID) were done. Half the specimen was frozen at -70° C and half formalin-fixed, paraffin-embedded for H&E and immunohistochemistry. PGE2 levels were determined by enzyme immunoassay. Subjects with ≥ 30% decrease in th...


Following a three month shut-down, the TiZir JV between MDL and Eramet has resumed production of titanium slag and high purity pig iron at its ilmenite upgrading facility in Norway, with shipments of chloride slag expected in early April.

TiZir, the joint venture (JV) between ASX-listed Mineral Deposits (MDL) and French multinational mining and metallurgy company, Eramet, has resumed production of chloride titanium slag and high purity pig iron.

MDL confirmed that ramp up at the Titanium & Iron ilmenite upgrading facility (TTI) in Tyssedal, Norway was proceeding as planned following a three month shut-down for furnace relining and capacity expansions last year.

"Both products are to required specifications and were produced using ilmenite from the Grande Cote mineral sands operation," MDL said.

The company added that shipments of chloride slag are expected to resume in early April.

TTI has the capacity to produce over 200,000 tpa upgraded TiO2 feedstock at full production.

TTI is part of TiZir, a 50:50 JV between MDL and Eramet. TiZir owns the Grande Cote mineral sands operation in Senegal, West Africa, which ships material to TTI in Norway for processing.

The first batch of Grande Cote ilmenite was produced at the facility in Q2 2015.


gest that this use of the book was far from the author's intentions. However commendable such a standpoint may be, it is almost invariably assumed to the detriment of the really serious study of the subject. As an examination compendium the volume has much to recommend it; but as a contribution to the science of anthropology it is much less satisfactory. The illustrations are numerous but often crude and harsh. G. H. P.


It is widely recognised that rural Australians experience lower participation in post secondary education and professional training than their urban counterparts. Barriers to post secondary education for rural persons have been identified as unavailability of training, inaccessible locations, personal and financial costs, limited employment opportunities, and poor quality educational services (National Board of Employment, Education and Training, 1991: 31). This is a widely acknowledged problem in the health services field in Australia, both in terms of training to provide basic qualifications and ongoing professional development as evidenced by Griffiths, Dunn and Ramanathan (1996), Alston (1996), and Williams, Rayner, Austin, McDonald and Gray (1997). Sawyer and Munn (1996: 31) found that 77 percent of health professionals in their sample identified lack of access to training, lack of peer contact and isolation as primary problems of disadvantage in working in rural communities. The seriousness of the problem was reflected in the National Think Tank project conducted at the University of Newcastle in 1998. It brought together service providers, consumer groups, policy makers and educators to explore strategies for dealing with service delivery and training of rural health workers in rural and remote areas of Australia (Eddy: 1998).


The emergence of multidrug-resistant bacteria demands innovations in the development of new antibiotics. For decades, the glycopeptide antibiotic vancomycin has been considered as the "last resort" treatment of severe infections caused by Gram-positive bacteria. Since the discovery of the first vancomycin-resistant enterococci strains in the late 1980s, the number of resistances is steadily rising with often life-threatening consequences. As an alternative to the generation of completely new substances, novel approaches focus on structural modifications of established antibiotics such as vancomycin to overcome these resistances. Here, we provide an overview of several promising modifications of vancomycin in order to restore its efficacy against vancomycin-resistant enterococci.


For wireless communication systems, the antenna is one of the most critical components for transmission as well as reception point of view. Good design of the antenna can relax system requirements and improve overall system performance. In addition to receiving or transmitting energy, an antenna in an advanced wireless system is usually required to optimize or accentuate the radiation energy in some directions and suppress it in others. Thus the antenna must also serve as a directional device in addition to a probing device. Many applications require radiation characteristics that may not be achievable by a single element. It may, however, be possible that an aggregate of radiating elements in an electrical and geometrical arrangement (an array) will result in the desired radiation characteristics [1]. The arrangement of the array may be such that the radiation from the elements adds up to give a radiation maximum in a particular direction or directions, minimum in others, or otherwise as desired. In this paper we concentrated on the electrical and geometrical properties of array elements that give a radiation maximum in a particular direction and minimum in others. We investigate the binomial and chebyshev distribution for linear and rectangular dielectric resonator antenna array.


Abstract The investment decision making process for small business is expected by the literature to focus on alternative objectives to shareholder wealth maximisation. This empirical study of 238 small businesses in New Zealand closely examines the investment decision making criteria used by small businesses. 'Gut feel' and accounting based methods are most used, even when adjusting for size and for external sources of capital. This supports the notion that utility is not just maximised wealth. Yet, most firms do discriminate in their investing on the basis of risk, usually by using non NPV criteria. While 69% indicate that they encounter limits to their investing due to availability of capital, they consider availability of capital as their least important constraint. This paper provides empirical support for the assertion that "there is a difference between what they ought to do... and what they actually end up doing" (Ang (1992)).


Longleaf pine savannas are highly threatened, fire‐maintained ecosystems unique to the southeastern United States. Fire suppression and conversion to agriculture have strongly affected this ecosystem, altering overstory canopies, understory plant communities, and animal populations. Tree thinning to reinstate open canopies can benefit understory plant diversity, but effects on animal communities are less well understood. Moreover, agricultural land‐use legacies can have long‐lasting impacts on plant communities, but their effects on animal communities either alone or through interactions with restoration are unclear. Resolving these impacts is important due to the conservation potential of fire‐suppressed and post‐agricultural longleaf savannas. We evaluated how historical agricultural land use and canopy thinning affect the diversity and abundance of wild bees in longleaf pine savannas. We employed a replicated, large‐scale factorial block experiment in South Carolina, where canopy thinning was applied to longleaf pine savannas that were either post‐agricultural or remnant (no agricultural history). Bees were sampled using elevated bee bowls. In the second growing season after restoration, thinned plots supported a greater bee abundance and bee community richness. Additionally, restored plots had altered wild bee community composition when compared to unthinned plots, indicating that reduction of canopy cover by the thinning treatment best predicted wild bee diversity and composition. Conversely, we found little evidence for differences between sites with or without historical agricultural land use. Some abundant Lasioglossum species were the most sensitive to habitat changes. Our results highlight how restoration practices that reduce canopy cover in fire‐suppressed savannas can have rapid benefits for wild bee communities.


Based on the statements of contemporaries of that era - prominent bishops, hierarchs of the Russian Orthodox Church, press materials, regulatory and other documents, the article considers the problem of the crisis of Russian religious consciousness in pre-revolutionary Russia. Based on the method of generalization of spatio-temporal characteristics (typological), an argument is given of its main causes. The historical and anthropological method allowed us to study the period under review through its perception in the minds of famous contemporaries - Saint Righteous John of Kronstadt, Archbishop Nikon (Rozhdestvensky), Metropolitan Veniamin (Fedchenkov), etc. Using the method of comparative analysis, it was possible to identify the specifics of the influence on the origin and development of the religious crisis consciousness of various social strata and social classes (nobility, intelligentsia, clergy).


THESE lines involve, to begin with, a mythological difficulty. Who is Palaemon, the companion of Neptune and the associate of Hercules ? Editors of the Rudens suggest that the Greek sea deity Palaemon, who is Neptuni comes, may also, naturally enough, be called the socius of Hercules, ' the god of travel by land and sea.' Admittedly the latter association is vague, if not unwarranted. The Greeks recognised two deities with the title Palaemon— viz., Heracles Palaemon (The Wrestler) and Melicertes Palaemon. The connecting link is the Phoenician Melcarth. Mythological dictionaries give, with some variation and uncertainty, the following account. Melcarth, the strong god who travelled about the world subduing monsters and otherwise helping mankind, bore so strong a resemblance to Heracles that the Greeks equated the two. Later the same Melcarth approximated to Poseidon and became a subordinate sea god, Melicertes, with the cognomen Palaemon. This cognomen more properly belonged to Heracles, but, because the identification with Heracles Palaemon was more original, it passed over to the new deity as a traditional epithet.


Abstract A full and rigorous examination of the theoretical and empirical underpinnings of residential group care with respect to their implications for current service policy, practice, and future research is long overdue and ought to receive the highest priority on the new century's emergent agenda.


It describes the application of the Narrative Interview technique as a data collection technique for social investigation. One of the aims of the technique is to construct or reconstruct a fact from personal narratives in different contexts. This type of interview, combined with several procedures in the investigation of everyday phenomena, is used in a multitude of situations, in addition to being an attempt to capture in the speech of the people the feelings expressed there. The work consists of bibliographic research about the characteristics of this technique, as well as some examples of its application in the scope of Information Science. Among the main results, he highlights that the narratives produced in terms of experiences and sharing are very rich and capable of bringing human beings closer together, so that together they can produce changes in various realities. He observes that the Narrative Interview presents itself with potential in the generation of information, being able to contribute to the studies in Information Science, especially in the case of the themes of memory, reading and mediation, which integrated the reported investigations.


In this paper, we propose beamforming techniques based on virtual signal-to-interference-plus-noise ratio (VSINR) maximization for weighted sum-rate (WSR) maximization in multiple-input single-output (MISO) interference channels. In the earlier work by Zakhour and Gesbert, it was shown that all Pareto-optimal beamformers can be expressed as a solution to the VSINR problem. However, how to choose the weight coefficients in the VSINR expression is not addressed when solving the WSR maximization problem. Thus, we provide a method of computing the weight terms to achieve a certain desired WSR maximizing point. Since the beamforming vectors in the proposed scheme should be computed as a function of global channel state information (CSI), we also propose a decentralized approach which shows a performance close to the centralized scheme with a significant reduction in the CSI exchange overhead.


The FlexPLI GTR tool has been implemented with an Upper Body Mass (UBM) representing portion of the torso mass, hip joint rotation and the response time lag between leg and the upper body during pedestrian to vehicle accidents. The new FlexPLI GTR UBM tool improves the test method at the end of the bumper test area of vehicle by eliminating unrealistic rotation of the FlexPLI GTR without UBM, bringing it closer to human lower extremity kinematics and loading. The tool is an enhancement to the current dummy technology by improving the pedestrian safety. The key benefit is that the UBM can be added to the existing standard FlexPLI GTR hardware being used in the current test procedures. The FlexPLI GTR UBM finite element (FE) model is developed and validated against a selected test condition. The geometry and connectivity for the FlexPLI GTR UBM FE model are obtained from the hardware design. Material testing was carried out to obtain the material properties and implementation to the FE model for the rubber element representing the hip joint stiffness during rotation of upper body mass. The initial findings of the FlexPLI GTR UBM FE model reveal that the model showed promising predictability for the simulated load-case. INTRODUCTION In US, on an average a pedestrian was killed nearly every 1.5 hours in traffic crashes and accounted for 16% of all traffic fatalities in 2016 [1]. In the same year, 5320 pedestrian died in road accidents in the EU which is 21% of all road fatalities [2]. The lower limb was found to be the most frequently injured body region with AIS 2 to 6 level injuries in 32.6% of pedestrian accidents worldwide. In 1998, the European Enhanced Vehicle-Safety Committee proposed a test procedure to assess protection to the lower extremity of a pedestrian during a collision [3]. A legform Impactor composed of rigid long bones was utilized in this procedure. As opposed to a legform impactor with rigid bone parts, the Flexible Pedestrian Legform Impactor (FlexPLI) is more biofidelic especially for its long bone parts, which have human-like bending characteristics [4]. The FlexPLI also provides extended injury assessment capabilities, including long bone bending moment at multiple locations and knee ligament elongations in comparison to other pedestrian legforms [4]. In 2005, the FlexPLI Technical Evaluation Group (Flex-TEG) was settled under the ECE/WP29/GRSP/Informal Group on Pedestrian Safety in order to evaluate FlexPLI hardware performance. Another objective of the FLEXTEG was to assess the impactor as a regulatory purpose test tool for a Global Technical Regulation on Pedestrian Safety (PS-GTR).

ABSTRACT
In this article, the relationship between 'trust' and 'civic engagement' which are supposed to be the main indicators of social capital and religious order have been evaluated. While trust has been elaborated in terms of "social trust", "trust among religious orders" and "trust to non-Islamic groups", civic engagement has been analyzed with regards to the dimensions of formal and informal interactions and voluntary donations. For this aim, the findings of a field survey carried out in Kahramanmaras by 400 people have been used. At the first level of analysis, religious order and at the second level the extent of religiosity of those orders has been taken as independent variable and the relationship with indicators of social capital has been explored.
Keywords: Social Capital, Religous Order, Religiosity, Civic Engagement, Trust


Mass transfer coefficients have been determined for the dissolution of Na2S2O3·5H2O crystals in water under conditions of turbulent agitation in a mixing vessel. The dissolution was carried out in a steady-flow process in which the area of selt crystals and the concentration of the solution in the mixing vessel were constant during each run. A comparison is made with previously unpublished results for batch runs in a similar system, and a method is developed for calculating the surface area of salt particles suspended in the mixing vessel under steady-flow conditions.


Abstract Background Common infectious agents, such as Toxoplasma gondii (T. gondii) and several human herpes viruses, have been linked to increased risk of self-harm. As the infections may be prevented and treated, information on the possible association on common infections and suicidal outcomes may help prevent self-harm. We aimed to investigate the associations between self-harm and seropositivity to T. gondii, Epstein-Barr virus (EBV), Herpes Simplex virus Type 1 (HSV-1), and Cytomegalovirus (CMV). As depression is a major risk factor for suicidality, we also investigated whether being seropositive to the studied herpes viruses was associated with depressive symptoms. Methods IgM and IgG antibodies to T. gondii, EBV, HSV-1, and CMV were measured in a large Finnish population survey, the Health 2000 project, in year 2000. The 6250 participants were followed for 15 years via health care register and causes of death register. In addition, lifetime suicidal ideation and suicide attempts were assessed in a smaller subsample of 694 participants, based on systematically-evaluated self-report, medical records, and register data. The participants in the subsample were screened for possible psychotic symptoms or were controls; we controlled for this screen status in the regression models. Results We found no significant cross-sectional associations between baseline depressive symptom and the herpes infections, when controlling for background variables related to infection seropositivity. During the follow-up, 18 of the 6250 participants (0.3%) had either died by suicide or had a self-harm diagnosis. In Cox regression models, serological evidence of lifetime or acute infections was not found to be associated with these suicidal outcomes. In the subsample, 31% had had suicidal thoughts and 13% had attempted suicide. There were no significant associations between suicidal thoughts and infection seropositivity / antibody levels. However, those seropositive for IgG class antibodies for CMV, measuring latent infection, had fewer suicide attempts compared to those seronegative in multinomial logistic regression models adjusting for gender, age, education, childhood family size, regional residence, and screen status (OR for multiple attempts compared to no attempts =0.45, 95% confidence interval 0.22‒0.91, p=.026). Genders were investigated separately in post-hoc analyses and there were significant associations only in males: suicide attempts were associated negatively with CMV and positively with EBV. Looking separately at diagnosis groups, the CMV association was significant among those with a mood disorder and not among those with a psychotic disorder. C-reactive protein (CRP) measuring inflammation seemed to explain some but not all of the associations. Discussion In a large sample nationally representative of the whole Finnish adult population, antibodies to CMV, EBV, or HSV-1 were not associated with depressive symptoms. Seropositivity or antibody levels of T. gondii or herpes viruses were not associated with risk of subsequent death by suicide or intentional self-harm diagnoses at a 15 year follow-up. In the subsample consisting mostly of participants with severe mental disorders, in males, EBV antibody level was associated with a history of a suicide attempt and none of the other infection variables were associated with a heightened risk for suicidal thoughts or acts. We found a heightened risk for multiple suicide attempts in persons belonging to the CMV seronegative minority. This "protective effect" of being infected with CMV calls for further research.


Objective The aim of this paper is to analyze mechanisms of motion regulation of tryptophan and branched-chain in chronic exercise central fatigue,through the analysis of tryptophan and leucine in serum in rat's model of chronic exercise central fatigue. Methods To set up the rat's model of chronic exercise central fatigue. To test the tryptophan and leucine in Rats' serum with HPLC-MS. Results Compared with the control rats,the level of tryptophan in exercise central fatigue rats reduces sharply and there is a significant difference( P 0. 05). There is no statistical difference in the level of leucine. Leu /Trp rises sharply with significant difference( P 0. 05). Conclusion There is a clear trend of declining in the level of tryptophan in the blood of rats under training with chronic exercise central fatigue. Because of the rising level of the ratio between leucine and tryptophan in branched-chain amino acids. It refines tryptophan to entering the central nerves system,regulating the occurring and development of the central fatigue. This alternation is possibly a self-regulation reaction in order to adapt to chronic exercise central fatigue.


A theoretical model is proposed to analyze the time-domain spectral phase en/decoding and evaluate the unconditional security of the optical code-based secure optical communication systems with DPSK modulation. The confidentiality of the systems with and without bitby-bit code scrambling technique is investigated. It mathematically proves that the system without code scrambling lacks confidentiality and the system employing code scrambling can realize unconditionally secure transmission. Furthermore, encoding only within the central band of the spectrum is sufficient for perfect secrecy, and the secrecy rate can be potentially improved. It allows the system to operate in the burst mode for code generation and encoding and thus have an idle time for rearm. © 2018 Society of Photo-Optical Instrumentation Engineers (SPIE) [DOI: 10.1117/1.OE.57.10


In this paper an attempt has been made to describe some of the psychodynamic factors in the homosexual pedophile. A description of the general research setting is followed by a discussion of 4 general formulations of the psychodynamics of the sexual offender. These are: 1. A consideration of the serious nature of the psychopathology present in the men studied, with indications that 76% of the homosexual pedophiles are using some type of schizophrenic adaptation. 2. The existence of marked fears of approaching an adult female sex object, with corresponding genital diminution fears. 3. Serious impairment of the capacity for abstract thinking, with impaired ability to utilize fantasy or other mechanisms involving abstractive capacity as an outlet for sexual conflicts and tensions. 4. Serious impairment of conscience formation, and resultant impairment of the restraining effects of conscience on overt behavior. The serious character of the psychopathology in the sexual offenders makes therapeutic approaches, ...


The itinerant helimagnet MnSi has been studied using NMR and susceptibility techniques above T c . The magnitude and temperature dependence of the 55 Mn Knight shift K, quadrupole coupling ν Q and the nuclear spin-lattice and spin-spin relaxation times T 1 and T 2 have been determined along with new high temperature measurements of the uniform susceptibility χ(0). Both K and ν Q are shown to be proportional to χ(0), with temperature the implicit parameter. T 1 and T 2 are temperature independent well above T c and their magnitudes cannot be explained by the fluctuations of localized moments. The results of all of our measurements are in general accord with the predictions of the renormalized RPA theory of spin fluctuation phenomena in itinerant magnets of Moriya and his collaborators.


: The nurse manager offers crucial leadership for safe work, settings, and maintaining the best environment for achieving high quality of patients' outcomes, these to achieve the organizational objectives. The improvement of skills, that it is often underestimated, where the nurse managers are vital to success. Strive nursing leaders as providers during their job transfer from a clinical place. Aim of the study : To assess nurse managers' competencies and its relation to their leadership styles. Setting: This study was conducted at the Oncology Center, Mansoura University. A descriptive correlational research design was utilized. Subjects: The sample was composed of all nurse managers who are working during data collection (n=65). Tools: 1) Nurse Managers competency inventory (NMCI), and 2) Nurse Managers leadership styles. The results revealed that more than half of nursing managers demonstrate a high level of domain conduct daily unit operations, while, slightly less than half of study nurse managers had a low level of total competency and the higher mean scores of transformational leadership style were observed which the nurse manager always uses the idealized influence. The study concluded that there is a highly statistically significant relation between the nurse manager's competencies and the leadership style nursing managers. The study recommended that management, competency development introduced & emphasized within the nursing curriculum; also an orientation management training program to be developed and conducted for new nurse managers regarding leadership, management functions and required skills, as well as how they deal with different situations.


Educational coaching can positively influence student learning in various ways. This study focuses on specific teachers' classroom-coaching behaviours (TCCBs) and explores their influence on student learning from a cross-cultural perspective. The study was conducted based on two samples of undergraduate students from China (N = 288) and the United States of America (N = 325). The results show that although TCCBs positively influenced students' learning variables in both samples, significant cultural differences in TCCB existed as perceived by Chinese and American students. Furthermore, TCCBs had stronger positive impacts on the American students' deep learning and academic buoyancy than on the Chinese students. The study attempts to explain cross-cultural differences in the impact of classroom coaching on student learning and offers practical recommendations for classroom coaching.


Combining with the design of 8th-order elliptic lowpass filter,a valid computer-aided method to design switched capacitor filters is discussed in this paper.After the switched capacitor network is transformed from time-varying topology into time-invariant topology and z-domain models of equivalent resistance using switched capacitor is obtained,a 2nd-order switched capacitor ellipse filter can be realized by assembling z-domain model,capacitor and operational amplifier models.Cascading the 2nd-order switched capacitor filters,the design of 8th-order switched capacitor for ellipse lowpass filter and its PSPICE simulation program have been given.The simulation results show steep attenuation and perfect transfer characteristics of ellipse lowpass filter,which are satisfied with the design specifications.The proposal can be used for designing and simulating highpass,bandpass,bandreject and other filter circuits.


The problem of MHD nanofluid flow over a rotating cone in the presence of thermal radiation has been investigated.

A parametric study of various emerging parameters are presented for velocity, temperature, nano particle volume fraction, Skin friction coefficients, Nusselt and Sherwood numbers in graphical and tabular form. The comparison of present results with the numerical results available in literature is made and our results are in very suitable agre ement with the known results. Also, the main features of the observations are examined and deliberated.


This article applies the concept of 'organized hypocrisy' to the self-determination process in the Western Sahara. A threefold analysis of the dysfunctions in the organizational outputs unveils, first and foremost, the UN'scommitment gap and lack of political will to act. To disguise it, the UN constantly promises reforms which also prove to be but institutional rhetoric decoupled from action. Lastly, contracting out the AU to the ongoing dispute also offers the UN a strategic mean of managing the pressures resulting of the gap between inconsistent logics of consequences and appropriateness. Against this background, the study concludes that UN's pragmatic peacekeeping approach in the Western Sahara aims at assuring the organization's survival at all cost, regardless of freezing and ossifying the far-reaching deadlock. This corroborates the argument that the likelihood of 'organized hypocrisy', as a response to conflicting demands, is inversely related to the efficacy of alternative means of managing conflicts. Keywords: Organized hypocrisy, peacekeeping, UN, Western Sahara self-referendum.


Microbiologically Induced Calcium Carbonate Precipitation (MICCP) through urea hydrolysis is the most effective way to precipitate a high concentration of calcium carbonate (CaCO3) within a short time. The MICCP process is used to remediate the micro-crack in the concrete. However, limited research has been conducted to determine CaCO3 precipitation by bacteria, especially in Malaysia. Here, Bacillus spp. isolated from the Malaysian stingless bee products were evaluated for CaCO3 precipitation. Bacillus spp. were selected for further study according to their ability to produce urease enzymes. The urease-positive Bacillus spp. were screened for CaCO3 precipitation by culturing on both CaCO3 precipitation agar and broth media. The survivability of the urease-positive Bacillus spp. in various temperatures, pH values, and NaCl concentrations were tested. Seven out of 11 Bacillus spp. were found as ureolytic bacteria. Among the ureolytic bacteria, bacteria belonging to the Bacillus subtilis species complex group showed the highest number of bacteria (36.4%) that are capable of precipitating CaCO3. Bacillus stratosphericus PD6 and B. aryabhattai BD8 exhibited the largest CaCO3 precipitation zones (15 mm). Bacillus stratosphericus PD6 also precipitated the highest amount of CaCO3 (65 mg) and urease activity (0.197 U/mL). All the urease-positive Bacillus spp. were able to grow at 45 °C, pH (8 to 12), and 5% NaCl. Only B. subtilis BD3 can withstand high temperatures up to 55 °C and 15% NaCl concentration. In conclusion, Bacillus spp. isolated from stingless bee products showed the ability as the CaCO3 precipitating bacteria; suggesting its potential application in self-healing concrete.


Abstract A combination of low serum calcium (Ca), high serum phosphorus (P), and low serum magnesium (Mg) has been observed in individual captive ruminants, primarily affecting kudu (Tragelaphus strepsiceros), eland (Taurotragus oryx), nyala (Tragelaphus angasii), bongo (Tragelaphus eurycerus), and giraffe (Giraffa camelopardalis). These mineral abnormalities have been associated with chronic laminitis, acute tetany, seizures, and death. Underlying rumen disease secondary to feeding highly fermentable carbohydrates was suspected to be contributing to the mineral deficiencies, and diet changes that decreased the amount of starch fed were implemented in 2003. Serum chemistry values from before and after the diet change were compared. The most notable improvement after the diet change was a decrease in mean serum P. Statistically significant decreases in mean serum P were observed for the kudu (102.1–66.4 ppm), eland (73.3–58.4 ppm), and bongo (92.1–64.2 ppm; P < 0.05). Although not statistically significant, mean serum P levels also decreased for nyala (99.3–86.8 ppm) and giraffe (82.6–68.7 ppm). Significant increases in mean serum Mg were also observed for kudu (15.9–17.9 ppm) and eland (17.1–19.7 ppm). A trend toward increased serum Mg was also observed in nyala, bongo, and giraffe after the diet change. No significant changes in mean serum Ca were observed in any of the five species evaluated, and Ca was within normal ranges for domestic ruminants. The mean Ca:P ratio increased to greater than one in every species after the diet change, with kudu, eland, and bongo showing a statistically significant change. The results of this study indicate that the diet change had a generally positive effect on serum P and Mg levels.

During the pre-COVID-19 pandemic, mobile learning is just an optional or a supplementary module in learning process. However, when the pandemic hit the world in the middle of 2020, a large number of students were forced to move from traditional learning process to online learning. This has become a critical issue especially for new online learners. Usability of a mobile learning application is important in ensuring that learners are able to learn efficiently and effectively with ease. This study evaluates the usability of the Brighten mobile application;a Moodle-based Learning Management System (LMS) which is currently used by all Universiti Tenaga Nasional's students. The evaluation is based on People at the Center of Mobile Application Development (PACMAD). The results indicate that Brighten mobile application is acceptable in terms of usability's effectiveness, efficiency, learnability, memorability and error-tolerance. Learners' satisfaction level shows a "marginally acceptable" result based on the SUS Adjective Rating Scale and the result for cognitive load shows that the highest cognitive load was in terms of the performance factor.


The theory of magnetic field generation due to the interaction of short relativistic laser pulses with underdense plasmas has been developed. The magnetic field is generated due to the inverse Faraday effect occurring with a circularly polarized laser pulse. The spatial distribution of the magnetic field is investigated. It is shown that the magnetic field magnitude depends on the relationship between the laser beam radius and the plasma skin-depth.


We find the best possible constants $K_i = K_i (\varphi )$, $i = 1,2$, for inequalities of the kind \[f(t)\int_0^t {\varphi (f(s))ds \leqq K_i \varphi (f(t))} \int_0^t {f(s)ds} \] when $\varphi $ is a given positive function, valid for all functions f such that $f(0) = 0$ and either $(i = 2)f$ is increasing and convex, or $(i = 2)f$ is increasing.


This paper presents a concept for an on-board spacecraft energy management system utilizing an expert systems approach. The energy management system continuously monitors and predicts the power capability of the spacecraft power subsystem, determines the overall electrical load profile, defines necessary changes to the initial equipment timeline, and implements new mission timeline and electrical load sequencing activities with little or no ground intervention. The system is intended to not only permit continued spacecraft operation in a degraded power subsystem state due to internal or external causes, but also to significantly optimize mission operation via maximum utilization of available power. The paper discusses the present state of the art of artificial intelligence technology and why the expert system is an attractive option to automate the energy management system for high power spacecraft.


The cestodes in the present collection were collected at the Biological Laboratory of the Carnegie Institution of Washington at Dry Tortugas, Florida, in I930-I932 by Dr. H. W. Manter, under whose direction this study was made. Of the sixteen species reported, fourteen have been previously described, and two species seem to be new. Thirty species of cestodes of fish have been previously reported from Tortugas (Linton, I909, and Potter, I937). In this paper are given six new locality records and eleven new host records, as well as descriptions of two new species. New locality records are indicated by #; new host records by *.


This paper describes the results of a study aimed at defining methodological tools and the implementation of a calculation model, whose object is to plan the management of emergency situations that can occur on road transport networks in case of exceptional events of different origin; in fact, during these crisis events, such road networks are asked to allow the circulation of rescue vehicles. An emergency situation, due to exceptional events, can become more critical in case of important traffic flows. These exceptional events can be divided into two categories: external events, among which the typical mountain events such as landslides and avalanches and the meteorological events connected to road transport in wintertime (e.g. ice formation, snow and floods); and internal events, caused by traffic (e.g. important accidents or other incidents typical of road operation). The above mentioned study aims at the operational definition of a decision-making support system (DSS), which consists of a database with geographical references on GIS support. This includes a set of computerized information for identifying the vulnerable network points on the basis of the supposable meteorological and hydro-geological events with road maintenance works also taken into account. A set of traffic models is included for the simulation of traffic flow and for the identification of alternative itineraries and a support system for the definition of traffic management plans. Traffic management interventions planned by means of the DSS contribute to define two different planning tools: Traffic Management Plans (TMP): whose goal is to define the alternative itineraries which detour normal traffic flows away from the area concerned with the aforementioned events; and Transport Emergency Management Plans (TEMP): whose goal is to define the shortest and the safer itineraries that rescue vehicles can use to reach the accident site, depending on the practicability of the concerned road network.

By means of two examples arising from physics we show that in contrast to a small perturbation of a regular boundary point, a small displacement of a singular boundary is singular in the sense that the expansions of the perturbed eigenvalues contain not only the integer powers of the small parameter involved, but also powers of the logarithm of this parameter. Examples considered are the Schrodinger equation for a hydrogenlike atom with nucleus of finite small size and the linearized shallow-water equation describing water waves trapped by a sloping beach.

The psychometric stability of the Armed Services Vocational Aptitude Battery was studied with data collected at 5 points over a 16-year period using item response theory (IRT) methods. Although 25 of the 200 items changed significantly over the years across 3 different gender-ethnic groups (i.e., White men, White women, and Black men), the overall characteristics of the tests were not severely affected by item-level changes. Items from tests that were more semantically laden were found to be more susceptible to the effects of time compared with those that focused on skills and principles. The findings are discussed in the context of the effects of time on the effectiveness of psychological measures. A call is made to test developers and test users to pay attention to the shelf life of their tests. The use of IRT methods for studying the effects of time on psychometrics is also discussed.

The Ka-Band Link Experiment was the first demonstration of a deep-space communications link in the 32to 35-GHz band (Ka-band). It wa.s carried out using the Mars Observer spacecraft while the spacecraft was in the cruise phase of its mission and using a 34-meter beam-waveguide research and development antenna at the Goldstone complex of the DSN. The DSN has been investigating the performance benefits of a shift from X-band (8.4 Glfz) to Ka-band (32 Gttz) for deep-space communications. The fourfold increase in frequency is expected to offer a factor of 3 to 10 improvement (5 to 10 dB) in signal strength for a given spacecraft, transmitter power and antenna size. Until recently, the expected benefits were based on performance studies, with an eye to implementing such a link, but theoo' was transformed to reality when a 33.7-GHz Ka-band signal was received front the spacecraft lay DSS 13. This article describes the design and implementation of the Ka-Band Link Experiment from the spacecraft to the DSS-13 system, as well as results from the Ka-band telemetry demonstration, ranging demonstration, and long-term tracking experiment. Finally, a preliminary analysis of comparative Xand Ka-band tracking results is included. These results show a 4to 7-dB advantage for Ka-band using the system at DSS 13, assuming such obstacles as antenna pointing loss and power conversion loss are overcome.


Objective: The aim of this study was to determine the enterococci species and antimicrobial resistance rates of enteroccus strains isolated from blood cultures of inpatients.
Materials and Methods: One hundred five Enterococcus spp. strains isolated from blood cultures sent from clinics at Osmaniye State Hospital Microbiology Laboratory between January 2011-December 2013 were included. The isolates were identified by conventional methods and Vitek 2 automated system. Antibiotic susceptibility tests were performed by disk-diffusion method and E-test. Statistical analysis was performed using chi-square test.
Results: Enterococcus spp. strains evaluated, 54(51.4%) were identified as E.faecalis and 51(48.6%) as E.faecium. General Intensive Care Unit(GICU) is the section where most frequently isolated species of both enterococci. Other clinics were Dialysis unit, and Internal Medicine clinics. E.faecium strains were found to be resistant to ampicillin, erythromycin, ciprofloxacin. Resistance rates of E.faecalis strains against ampicillin, erythromycin, ciprofloxacin were 47%, 70.5%, 11.8%, respectively. High-level resistance to gentamicin and streptomycin were determined in 55.6%, 83.3% of E.faecium strains and in 23.5%, 11.8% of E.faecalis strains, respectively (p≤0.05). Two of E.faecium strains and 1 of E.faecalis from GICU were found to be resistant to teicoplanin and vancomycin. Linezolid was found most effective drug and resistance wasn't determined in none of the strains.
Conclusions: Three vancomycin and teicoplanin resistant strains isolated from blood cultures in our hospital show that the isolates mentioned above may cause significant problems in the future. In addition, linezolid may be a good alternative for the treatment of the resistant enterococcal infections in our hospital.


In Technical Report EE98024, the authors present a closed-form expression for the quan-tiication of model error in transfer function estimation by characterising undermodelling by a random walk process in the frequency domain. The present note shows that, for systems with resonant modes, less conservative model error quantiications may be obtained by alternatively characterising undermodelling by an integrated random walk process in the frequency domain. In Goodwin et al. (1998), the authors have described an approach to transfer function model error quantiication based on non-stationary stochastic embedding in the frequency domain. The end result of their proposal is a closed-form stochastic characterisation of the model errors due to noise and un-dermodelling. This characterisation has proved to eeectively capture typical cases of undermodelling found in practice (Goodwin, 1999). The modelling error characterisation in the aforementioned paper, however, may be overly conservative at low frequencies for systems with lightly damped modes at high frequencies. Speciically, a system with a lightly damped mode displays a large peak in its frequency response, thus if un-modelled this peak will introduce large undermodelling at the frequencies where it occur. Large undermodelling at high frequencies may propagate as excessively large undermodelling at lower frequencies , because the rate at which the sizee of the undermodelling can vary with frequency is restricted by the variance growth of the non-stationary embedded process; in Goodwin et al. (1998): a random walk.


Software engineers use record/replay tools to capture use case scenarios that can serve as regression tests for web applications. Such tests, however, can be brittle in the face of code changes. Thus, researchers have sought automated approaches for repairing broken record/replay tests. To date, such approaches have operated by directly analyzing differences between the releases of web applications. Often, however, intermediate versions or commits exist between releases, and these represent finer-grained sequences of changes by which new releases evolve. In this paper, we present WATERFALL, an incremental test repair approach that applies test repair techniques iteratively across a sequence of fine-grained versions of a web application. The results of an empirical study on seven web applications show that our approach is substantially more effective than a coarse-grained approach (209% overall), while maintaining an acceptable level of overhead.


Enterohemorrhagic Escherichia coli (EHEC) O157:H7-secreted cytotoxins are toxic to target cells and enhance colonization of intestinal tissues in disease-susceptible animals. It is unclear what role, if any, EHEC O157:H7-secreted cytotoxins play in the colonization of intestinal tissues of healthy reservoir animals. We previously reported that EHEC O157:H7 colonization sites were associated with focal hemorrhages in the jejunum and descending colon of persistent shedding cattle, suggesting a potential role for cytotoxins in EHEC O157:H7 colonization. We have used a traditional EHEC O157:H7 IVOC adherence assay and a novel lawn assay to examine the role of EHEC O157:H7-secreted cytotoxins in EHEC O157:H7 strain colonization of the jejunum and descending colon of non-persistent and persistent shedding cattle. Four EHEC O157:H7 strains that were previously reported to differentially colonize cattle produced cytotoxins that were differentially active against epithelial cells from the jejunum and descending co...

In order to apply the technology of induction heating to crankshaft shrinkage fitting,it is proposed to set a circular coil inside the hole of crank cheek,simultaneously,a rectangle coil is set between the hole of crank cheek and crank pin.By establishing a FEA model of crank arm,some numerical simulation work about the temperature field in induction heating of the crank arm is performed by ANSYS software under different coil parameters condition,which results show that uniform temperature field around the hole of crank arm can be obtained by adjusting the current density and frequency of the induction coils.Accordingly,the crankshaft may reach high quality of shrinkage fitting.In addition,the influence factors of induction heating are discussed.


This applied research project responds to a critical problem in health and development: how to effectively translate our research evidence to the communities with and for whom we work in order to stimulate successful, sustainable health promotion activities and social change. The tangible product of this research is a handbook for health and outreach workers from immigrant communities from the Horn of Africa living in Toronto. The handbook is a resource which will be used as a starting point for the generation of community-based health initiatives, in this case, HIV/AIDS prevention programs. The research applies a conceptual approach which emphasizes participatory action research theo1y and methodology, and equitable, transcontextual research partnerships. It uses a model which merges both scientific evidence and experiential (ethnographic) evidence of risk and vulnerability to create new understandings on which to base the development of health programs. Stories, grounded in ethnographic evidence, are at the heart of the research strategy. The handbook is an example of experimental ethnographic writing: dialogue is used to communicate research evidence, health, and skills information; and a number of personal narrative:s have been constructed as resources to help health workers generate dialogue on issues of risk and vulnerability, and begin a process of reflection


We first comment on numerical simulations of THz emission generated by two-color filaments (fundamental pump pulse coupled with its second harmonic) in an argon gas. We show the existence of characteristic spectral signatures and report a noticeable growth of the THz signal when increasing the pump wavelength. Second, we develop a onedimensional model of THz emissions induced by laser-driven, time-asymmetric ionization and current oscillations in a hydrogen gas. Our model highlights complex scalings of the THz fields with respect to the laser and gas parameters. Analytical expressions of the transmitted and reflected fields are presented, explaining THz spectra observed in PIC and forward-pulse propagation codes. e backward-propagating THz wave is mainly driven by the electron current oscillations at the plasma frequency, and its resulting spectrum operates below the plasma frequency. e transmitted THz wave is emitted from both plasma current oscillations and photo-ionization. eir respective signal presents a contribution below and around the plasma frequency, plus a contribution at higher frequencies associated to the photo-induced current.
