WebQuest instructional strategy has been recognized to be an effective learning strategy for decades. Teachers encourage students to participate in the process of searching for knowledge, reorganizing the information they have found and evaluating their performance on different topics in web-based learning environment. In addition, self-regulation issue is always the crucial key to a successful WebQuest learning activity. In this study, we aimed to investigate that students' self-regulation ability will be encouraged in context-aware ubiquitous learning environment by situating the students and helping them to learn in the real world. WebQuest has seldom been applied to second-language course. Therefore, this study will conduct a WebQuest context-aware ubiquitous leaning activity for English course on the campus. Three language learning tasks will be conducted in the playground, resource recycling dump and library. The students in the experimental group will be asked to find knowledge of English teaching content and use this information to finish WebQuest learning task in the real environment, while the students in the control group will learn through general mobile English learning system. After finishing the learning activity, the students' learning performance will be evaluated accordingly.


Abstract Student involvement in extracurricular activities has the potential to contribute to a variety of valued college outcomes. The purpose of this study was to understand the outcomes associated with recreation students' participation in the Professional Golf Management Student Association, as well as the experiences that contributed to those outcomes, using qualitative research. Four major themes that represented the experiences and outcomes of student involvement emerged from in-depth interviews. These themes suggested students had their needs for relatedness, self-determination, competence, and enjoyment met through their club involvement. All students reported that their club involvement contributed to their sense of belonging and identification with their peers and academic program. The students, especially those involved in club leadership roles, believed they could make a difference in the success of their club, academic program, and community through their club involvement and that they were also developing important interpersonal and professional skills. Finally, the students reported that involvement in the association contributed to the enjoyment of their academic program and the creation of meaningful memories.


E-government has been a global trend in the world. Many countries around the world have implemented E-government since it is believed could give substantial benefits to citizens, businesses, and governments. The aim of e-government is to support the modernization of the public sector, enabling its transparency and effectiveness. With regard to these significant outcomes, e-government could streamline the economic and social development of a nation, including Indonesia. This paper aimed to review the literature on e-government implementation and its future perspective in Indonesia. The inclusion criteria were e-government trends around the world, application of e-government in Indonesia, the factors and the impact of e-government. This study revealed the critical factors that could affect the implementation of e-government in Indonesia. In addition, e-government has a potential to increase transparency, citizen engagement, and gross domestic product (GDP) growth in Indonesia.


The performance of frequency hopped OFDM cellular system depends on the designing of frequency hopping sequences. This paper explores fast frequency hopped OFDM in the link level of a cellular communication system. Each user is assigned several sub-carriers by the base station in each cell in every time slot according to the predetermined hopping sequences. The frequency hopped OFDM technique based on orthogonal hopping sequences can improve communication performance in a cellular system since it could minimize intra-cell interference and average inter-cell interference. In this paper, Welch-Costas array pattern is derived under independent and cluster hopping schemes, which enable us to evaluate the system performance with the Turbo code modulation scheme. Examples of the frequency sequences and how they are assigned to users are also given. We also simulate and analyze the impacts of the channel environment and parameters, frequency diversity, and inter-cell interference diversity on the performance of the coded frequency hopped OFDM cellular system.


The title compound [Cu2((μ-NO)2(aepy)4]ClO43 Cu2C28H40N9Cl3O14, Mr = 960.12, aepy = 2-(2-aminoethyl)pyridine) was synthesized and its crystal structure was determined by X-ray diffraction method. It crystallizes in monoclinic, space group C2/c with cell parameters: a = 21.958(3), b = 12.205(2), c = 15.180(3)A, = 106.06(1), V = 3909.5(12)A3, Z = 4, Dc = 1.631 g/cm3, F000 = 1968 and (MoK = 1.368 mm-1. The structure was solved by direct methods and refined by full-matrix least-squares techniques. The final R = 0.0734 and wR = 0.1954 for 1606 observed reflections with Iσ>2.0(I. The crystal structure revealed that the [Cu2(-NO2aepy4]3+ cation consists of two square-based pyramidal copper(Ⅱ)atoms bridged by one nitrate anion. The distance between the two copper atoms Cu1…Cu1A) is 5.373(2)A.


Thermoplastic starch (TPS) films containing relatively low [0.75 ± 0.08% (w/w)], intermediate [1.08 ± 0.04% (w/w)] and high [3.20 ± 0.29% (w/w)] levels of the antimicrobial (AM) agents carvacrol, linalool and thymol were prepared, and their physico‐mechanical and optical properties were evaluated. Addition of these AM agents to TPS film reduced the tensile strength with increasing AM agent content, with a significant effect observed at the highest AM agent concentration. The Young's modulus and elongation at break increased with increasing AM agent concentration, especially at the highest formulation concentration of AM agent. Films having a low or intermediate formulation concentration of AM agent exhibited no significant effect on their water vapour permeability, transparency and thermal properties when compared to the control film. Although scanning electron microscope imaging suggested a significant and progressive change in the surface morphologies of the films with AM agent concentration, the overall effects on the tested properties were not significant. This suggests that the direct incorporation of AM agents into TPS films did not adversely affect the films, particularly at lower AM agent concentrations. Copyright © 2013 John Wiley & Sons, Ltd.


The TOEIC test is taken by many company employees throughout Japan every year. In some cases, the students who take the test are not ready to do so. They lack the basic skills necessary in grammar, reading and listening to obtain a score of 400 or over. Part of the problem also lies with their method of study. Too often do they expect the teacher to do everything for them, hoping this will raise their score sufficiently. This study looks at a six month TOEIC program that was designed with learner autonomy in mind and implemented at a major electronics firm in Japan. The program was aimed at low level TOEIC students and was designed to increase their scores by 50 points or more. Results indicated significant improvements in most scores upon completion of the program, suggesting that a learner-centered approach toward teaching TOEIC can be effective in helping Japanese students raise their overall test scores.


Ordinary institutions of higher learning to train students for sports awareness, in addition to raising awareness of students, the more important is to strengthen the school sports curriculum, teaching sports content, teaching methods reforms, and organically integrate them. Only in this way in ordinary schools to train students and the implementation of the popular fitness plan can be implemented lifelong sports concept.


Program Number: 5528 Poster Board Number: B0099 Presentation Time: 8:30 AM–10:15 AM Neuroprotective Effects of Amnion-derived Cellular Cytokine Solution (ACCS) in Experimental Optic Neuritis Reas Sulaimankutty1, Kimberly Dine1, Helayna Brown1, Larry R. Brown2, Kenneth S. Shindler1. 1Ophthalmology, Univ of Pennsylvania, Scheie Eye Inst, Philadelphia, PA; 2Stemnion Inc, Pittsburgh, PA. Purpose: Optic neuritis is a demyelinating inflammation of the optic nerve that often occurs in multiple sclerosis (MS) patients. Loss of retinal ganglion cells (RGCs) and their axons also occurs in optic neuritis, and correlates with permanent vision loss. ACCS is a novel biologic mixture of growth factors and cytokines secreted from Amnion-derived Multipotent Progenitor (AMP) cells, that exhibits anti-inflammatory and neuroprotective properties in a variety of disease models. The ability of ACCS to suppress optic neuritis in the experimental autoimmune encephalomyelitis (EAE) model of MS was examined. Methods: EAE was induced in C57/BL6 mice by immunization with myelin oligodendroglial glycoprotein peptide. Mice were treated daily with one drop (6 uL) of ACCS intranasally beginning before or after onset of optic neuritis. Visual function was assessed by optokinetic responses (OKR) at baseline, then weekly until sacrifice 6 weeks post-immunization. Retinas and optic nerves were isolated. RGCs were immunolabeled with Brn3a antibodies to quantify RGC survival. Inflammation was assessed by H&E and Iba1 (macrophage/ microglia marker) staining, demyelination by luxol fast blue staining, and axonal loss by neurofilament staining of optic nerve sections. Results: Progressive decreases in OKR occurred in vehicle-treated EAE mice, along with significant RGC loss, consistent with prior studies showing onset of optic neuritis occurring 12-15 days after EAE induction. Daily intranasal ACCS treatment beginning on day 0 (day of immunization), 15, 22, or 30, significantly reduced the level of vision loss, and treatment from day 0 or day 15 significantly attenuated RGC loss. ACCS also decreased the degree of demyelination and axonal loss, but had limited effects on the level of inflammation in the optic nerve. Conclusions: ACCS treatment attenuates RGC loss, preserves OKR responses, and reduces demyelination and axonal loss during experimental optic neuritis in EAE mice. ACCS exerts effects with treatment initiated before and after onset of optic neuritis, suggesting it may be useful as a preventative or abortive therapy. Results suggest ACCS is a potential treatment for optic neuritis that warrants further study. Furthermore, potent effects seen after intranasal administration suggest this may be a novel drug delivery method for optic neuritis.

Shindler, Stemnion Inc (F) Support: NIH Grant EY019014 Program Number: 5529 Poster Board Number: B0100 Presentation Time: 8:30 AM–10:15 AM Experimental optic neuritis induced by the microinjection of lipopolysaccharide into the optic nerve Marcos Luis Aranda, Damian Dorfman, Pablo Sande, Ruth E. Rosenstein. Human Biochemistry, University of Buenos Aires /Sch of Medicine, Buenos Aires, Argentina. Purpose: Optic neuritis (ON) is a condition involving primary inflammation, demyelination, and axonal injury in the optic nerve which leads to retinal ganglion cell (RGC) loss, and visual dysfunction. We investigated the ability of a single microinjection of bacterial lipopolysaccharide (LPS) directly into the optic nerve to induce functional and structural alterations compatible with ON. For this purpose, optic nerves from male Wistar rats remained intact or were injected with vehicle or LPS. Methods: The effect of LPS was evaluated at several time points post-injection in terms of: i) visual pathway and retinal function (visual evoked potentials (VEPs) and electroretinograms, (ERGs), respectively), ii) anterograde transport from the retina to its projection areas, iii) consensual pupil light reflex (PLR), iv) optic nerve histology, v) microglia/macrophage reactivity (by Iba1and ED1-immunostaining), vi) astrocyte reactivity (by glial fibrillary acid protein-immunostaining), vii) axon number (by toluidine blue staining), vii) demyelination (by myelin basic protein immunoreactivity and luxol fast blue staining), viii) optic nerve ultrastructure, and ix) RGC number (by Brn3a immunoreactivity). Results: LPS induced a significant and persistent decrease in VEP amplitude and PLR,without changes in the ERG. In addition, LPS induced a deficit in anterograde transport, and an early inflammatory response consisting in an increased cellularity, and Iba-1 and ED1immunoreactivity in the optic nerve, which were followed by changes in axonal density, astrocytosis, demyelination, and axon and RGC loss. Conclusions: These results suggest that the microinjection of LPS into the optic nerve may serve as a new experimental model of primary ON.

Luis Inácio Lula Da Silva, originally a metalworker and trade union activist, was president of Brazil from 2003 to 2010, leading the largest country of Latin America, with more than 212 million people. In 2020, social and labour historian John D. French, with a long career devoted to Brazilian labour history, published the much acclaimed biography Lula and His Politics of Cunning: From Metalworker to President of Brazil.1 In this book, French explicitly aims to give a bottom-up account of Lula's life.


The ductile resistance of the fibre-metal laminates has been analysed experimentally on three various different FML laminates that is made up of aluminium sheets of three different thickness namely 0.2mm, 0.3mm & 0.4mm. Tensile and flexural tests on the specimens were carried out to analyse the ductile behaviour of the FML laminates. Stress vs strain curve for tensile and load vs displacement curve for flexural test. The respective parameters like ultimate stress, young's modulus, longitudinal strength, flexural failure, flexural modulus, etc., are calculated from the plots. The results were compared with each other to evaluate what is the impact of metal layer thickness in the FML plates. There is good variation between the experimental results is obtained. Finally the best fiber to metal ratio is found out and the result is justified.

Using the inflowing horizontal and vertical wind shears for individual pitch controller is a promising method if blade bending measurements are not available. Due to the limited information provided by a lidar system the reconstruction of shears in real-time is a challenging task especially for the horizontal shear in the presence of changing wind direction. The internal model principle has shown to be a promising approach to estimate the shears and directions in 10 minutes averages with real measurement data. The static model based wind vector field reconstruction is extended in this work taking into account a dynamic reconstruction model based on Taylor's Frozen Turbulence Hypothesis. The presented method provides time series over several seconds of the wind speed, shears and direction, which can be directly used in advanced optimal preview control. Therefore, this work is an important step towards the application of preview individual blade pitch control under realistic wind conditions. The method is tested using a turbulent wind field and a detailed lidar simulator. For the simulation, the turbulent wind field structure is flowing towards the lidar system and is continuously misaligned with respect to the horizontal axis of the wind turbine. Taylor's Frozen Turbulence Hypothesis is taken into account to model the wind evolution. For the reconstruction, the structure is discretized into several stages where each stage is reduced to an effective wind speed, superposed with a linear horizontal and vertical wind shear. Previous lidar measurements are shifted using again Taylor's Hypothesis. The wind field reconstruction problem is then formulated as a nonlinear optimization problem, which minimizes the residual between the assumed wind model and the lidar measurements to obtain the misalignment angle and the effective wind speed and the wind shears for each stage. This method shows good results in reconstructing the wind characteristics of a three dimensional turbulent wind field in real-time, scanned by a lidar system with an optimized trajectory.


Guksajeon in Songgwangsa has an unusual structure different from other general cases. The findings that some literature report the presence of renovation in the past and relevances of this reconstruction with the sixteen national monks seems to be ample evidence to confirm the hypothesis that the units in Guksajeon's front were originally three. It has, however, been extended to four in order to enshrine a portrait of the sixteenth monk, Kobong-Hwasang. It has a particular meaning in that this study found the change in a main building rather than in any others such as Yosachae or monks' accommodation houses. It can be interpreted that the structural change was deigned not for merely structural purposes but for containing an additional portrait of the national monk. That is a combination of the hardware, the structure and the software, the needs of the users and the time in the reconstruction.


Experimental proof is presented that coherent vortex motion can be realized in superconducting film bridges of variable thickness'' in the absence of the ordering action of magnetic and microwave fields even if the bridge dimensions greatly exceed the coherence length. (auth)


We are interested in the behavior of solutions to the damped inhomogeneous nonlinear Schr\"odinger equation $ i\partial_tu+\Delta u+\mu|x|^{-b}|u|^{\alpha}u+iau=0$, $\mu \in\mathbb{C} $, $b>0$, $a \in \mathbb{C}$ such that $\Re \textit{e}(a) \geq 0$, $\alpha>0$. We establish lower and upper bound estimates of the life-span. In particular for $a\geq 0$, we obtain explicit values $a_*,\; a^*$ such that if $aa^*,$ global existence holds. Also, we prove scattering results with precise decay rates for large damping. Some of the results are new even for $b=0.$


An integrated use of farmyard manure with fertilizer gave significantly maximum average grain yield (3.34 tonnes/ha) of rice (Oryza sativa L.) and (1.02 tonnes/ha) of lentil (Lens culinaris Medikus) during 1995-98. Application of neem cake-coated urea + P and K to rice resulted in significantly higher yields and uptake of nutrients by rice and succeeding lentil compared with rest of the treatments except integrated use of both, and farmyard manure alone for lentil yield. Soil fertility (N, P and organic carbon) was improved significantly with FYM used either alone or in combination with fertilizer over that of initial soil status. Potassium content in soil was reduced in all treatments.

The generalized analysis of the main objectives allows to claim creation of a complex of the fighting serviceman of equipment of the Armed Forces of Ukraine that performance of all goals and tasks on prospect has to be provided and be followed by the effective system of scientific research and scientific support of state programs, developments of all systems and elements of a complex fighting equipments (CFE). Therefore the analysis of global trends in development and experience of creation and/or improvement of CFE, synthesis of the general requirements (tactical and technical, operational, etc.) to it, justification of requirements to systems and elements of a complex fighting equipments of the military personnel of units of military intelligence of Ground forces of the Armed Forces of Ukraine is a relevant task.
For increase in opportunities of the certain serviceman at execution of fighting tasks need of carrying out broad experimentally theoretical tests on creation, operation and the directions of development of CFE in general, and the systems of power supply as a component of a complex fighting equipment, in particular exists by it.
The main criterion for evaluation of system effectiveness of power supply of CFE is an ensuring performance by the military personnel a task during a certain term and their survival after its performance by providing the CFE elements with electric energy without additional deliveries of expendables.
The analysis of modern CFE and also that which are developed according to the program under the name "Soldier of the Future" shows big saturation electronic devices which weak spot is power supply. So, the system of power supply is one of problematic issues of creation of CFE. Therefore, development of systems of power supply of the smilitary personnel self-powered that are capable to ensure functioning of CFE devices, throughout certain time, without restrictions of movement for the purpose of performance of a task by the serviceman is a relevant task.
Works on finishing characteristic of the system of power supply of a complex fighting to equipment to necessary level are carried out with use of new technological practices which are partially presented in this article. From them first of all it is necessary to pay attention to use of supercondensers and also to development of the Ukrainian scientists of the battery on the basis of tritium.
The location of the system of power supply is determined in a complex battle equipments of servicemen of subdivisions of military secret service of Ground forces of the Armed Forces of Ukraine and perspective directions of improvement of this system with the use of experience of leading countries of the world.


Transformation of a natural soil to agricultural land is generally assumed to be accompanied by increased mineralization of the organic matter and increased CO2emissions; in contrast, afforestation of agricultural soil is thought to lead to sequestration of carbon and incorporation of atmospheric CO2 into the organic matter. In other words the type of management and land use determine whether soils act as carbon sinks or sources, so that transformation of agricultural land to forest land is generally considered to be accompanied by an increase in edaphic carbon, although it is not clear whether this effect is always produced or if it depends on the agricultural history of the land being afforested.


The article proposes some notes on the notion of passivity developed in the maturity writings of the Jewish philosopher Emmanuel Levinas, considered one of the fundamental pillars on which his complex discourse on ethical subjectivity and responsibility to substitution is based. Achieved thanks to what the author himself calls the method of emphasis, the levinasian proposal on this notion is condensed in the iterative construction: "passivity more passive than all passivity." With this figure, the philosopher seeks, on the one hand, to take the notion beyond the uses that made the philosophical tradition and, on the other hand, to reach the final phenomenological foundation of his conception of ethical subjectivity that, breaking with his ontological enclave, is conceived as being otherwise


We report a 62-year-old female patient who came to our institution due to pain and limited movements in the neck area, nausea, and headache. The magnetic resonance imaging (MRI) revealed a single larger and two smaller lesions with the appearance of cavernomas in the left parietal brain region. The patient was consulted with a neurosurgeon and was judged to be inoperable. Radiosurgery was performed in the cavernoma with a total focal dose of 15Gy. 11 months after the radiotherapy, during a routine follow-up MRI scan, a tumor-like lesion with extensive perifocal edema and midline dislocation, with heterogenous structure and ring-like enhancement was reported in the left parietal brain region. After follow-up for 15 months, the last MRI showed almost complete reverse development of the described lesion, with marked reduction of volume, edema, and contrast enhancement. Along with MRI features of the lesion, some of which overlap with high-grade glioma characteristics, the evolution of the lesion is in favor of a radiation necrosis zone.


In two strains of rats the decrease in mitotic index was parallel to the radiation dose delivered. The recovery time also appeared to parallel the dose. These effects were more marked in the AH 130 than in the AH 7974 strains. In both, the mitotic index of the non-irradiated group and the slope of the mitotic index curve after irradiation were approximately the same, therefore the period of cell divisions was considered to be the sarne in both strains. In a comparison of the recovery curves the AH 7974 strain showed a slighter inclibation than the AH 130. Therefore, it was concluded that a delay in prophase was more nnarked in the AH 7974 than in the AH 130. (Absts. Japan. Med., 1: No. 6, 1961)


Killer strains of Saccharomyces cereuisiae are those carrying a 1.5 x 10'-dalton double-stranded (ds) ribonucleic acid (RNA) (Al) in virus-like particles and secreting a protein toxin. Most yeast (killer or not) also carry a 3 x 106 -dalton dsRNA (L). We have mapped mutations in eight of the chromosomal genes needed for maintainingM (mak genes). The mak genes are widely distributed on the yeast map, with no multigene complexes. We show that mutants defective in these and other mak genes lose M dsRNA, but not L dsRNA. The mak3-1 mutation results in markedly decreased cellular levels of L dsRNA, but mak3-1 strains do not lose L dsRNA completely. Mutation of makl6 results in temperature-sensitive growth, whereas mutations in makl3, makl5, makl 7, mak2O, mak22, and mak27 result in slow growth at any temperature. No effect of mak mutations on mating, meiosis, sporulation, germination, homothallism, or ultraviolet sensitivity has been found. The specificity of mak mutations is discussed.


Data integration is the problem of combining data residing in different sources, and providing the user with a unified view of these data. One of the critical issues of data integration is the detection of similar entities based on the content. This complexity is due to three factors: the data type of the databases are heterogeneous, the schema of databases are unfamiliar and heterogenous as well, and the quantity of records is voluminous and time consuming to analyze. Firstly, in order to accommodate the textual and numerical heterogeneous data types we propose a new weighting measure for the numerical data type called Bin Frequency Inverse Document Bin Frequency (BF-IDBF). Our proposed BF-IDBF measure is more efficient than histograms, when combined with Term Frequency Inverse Document Frequency (TF-IDF) measure for Heterogeneous Data Mining (HDM) by Unified Vectorization (UV). The UV permits to combine the algebraic models representing heterogeneous data documents, e.g. textual and numerical, which make the simultaneous HDM process simpler and faster than the traditional attempts to process data sequentially by their respective data type. Secondly, in order to handle the unfamiliar data structure, we use the unsupervised algorithm, Self-Organizing Map (SOM). Finally to help the user to explore and browse the semantically similar entities among the copious amounts of data, we use a SOM-based visualization tool to map the database entities based on their semantical content.


With the implementation of universal newborn hearing screening (UNHS) programs in the Unites States and the rapid increase in the number of states and birthing facilities conducting UNHS, the average age of identification of deaf or hard-ofhearing (D/HH) newborns has decreased over the last 20 years from approximately 30 to 48 months to 6 months or less. Although infants and young children are being identified earlier, those who are D/HH will likely fall behind their hearing peers in language, cognition, and social-emotional development. D/HH infants who receive intervention before 6 months maintain language development commensurate with their cognitive abilities through the age of 5 years.

An earthing grid is a critical part of a substation that ensures people's safety and reliable operation of equipment. It achieves this by providing a low resistive path to earth for high currents during transient conditions, and in doing so, it limits the ground potential rise (GPR), step voltage, and touch voltage present in the vicinity of the substation within their tolerable thresholds. In this paper, a substation earthing grid was modeled, and simulations were conducted to evaluate the impact of varying soil resistivity on the design and performance of a substation earthing grid using the Electrical Transient Analyzer Program (ETAP) following the IEEE Std 80–2013 guidelines. It was observed that the touch voltage and step voltage safety limits are affected by the varying soil resistivity, with the touch voltage being the most sensitive safety limit to the soil resistivity variation. When the soil resistivity is low, the safety limits thresholds are relatively high, and when the soil resistivity is high, the thresholds are low, affecting the quantities of the other design parameters required to satisfy the design criteria for the same available earthing grid area.


In vitro responses can be influenced by the developmental status of the donor plant tissue. The effects of the donor plant photoperiod and the developmental stage of the plant on organogenesis of petiole explants of Begonia×hiemalis cv. Schwabenland Pink are reported. Long day plants had progressively more branches, total stem length, leaf area, and branch and shoot mass. In short days, flowering was earlier and a greater proportion of dry weight accumulation was allocated to reproductive structures. Similar explant responses were obtained from all developmental stages until flowering was well advanced in short days and then the regenerative capacity diminished. Primary measurements of donor leaves (length, area and weight) at the time of explant removal were not well correlated with adventitious bud production. Loss of regeneration was not determined by tissue or plant age but was associated with the progressive development of flowers. Thus the donor plant photoperiod only indirectly affected bud production. Organogenesis decreased with duration of short days but increased in long days and thus both the duration of the multiplication phase and the intensity of the in vitro response was enhanced by maintaining donor plants in long days.


We propose a Modular Immersive Virtual Reality System that can be used towards the development of Immersive Virtual Environments (IVE) with variable sensor requirements that, in turn, are intended to be used to support experiments related to Virtual Exposure Therapy, Physical Therapy, and Rehabilitation. Specifically, by utilizing the Unity game engine and modular sensor architecture, the proposed system is aimed to support the development of virtual environments synchronized with multi-sensor input and output. Based on the intended usage, our system can be used to record user responses via built-in surveys and to accommodate for extensive robotics and sensor requirements focusing on synchronous user interaction and input.

By taking three 500 kV substations of Dongguan power grid as examples,this paper analyzes causes for overstandard of single-phase short circuit current of bus at 220 kV side in 500 kV substations and presents measures for limiting single-phase short circuit current.In accordance that the neutral point of autotransformer is connected to the ground by small reactor,the paper expounds the relationship between reactance value of small reactor and single-phase short circuit current as well as impact of small reactor on relaying protection.The scheme that no disconnecting switch should be installed between neutral point and small reactor in consideration of investment conservation and circuit simplification is recommended.Since the neutral point of 500 kV autotransformer was connected to the ground by small reactor in 500 kV substation in Dongguan power grid,considerable effect on limiting single-phase short circuit current has been achieved and adaptability of short circuit current level in substation to grid construction is strengthened.


We describe a CAD of E-plane filter structures for MVDS applications. The software package, EPFIL, was used for filter design and one actual filter implementation is presented. Measurements on a fabricated bandpass filter confirm the accuracy of the design procedure.


Summary Group treatments for men who abuse their female partners are relatively recent phenomena. These groups were developed with the encouragement of the battered women's movement, and in the mid- to late-1970s, were seen by advocates as a crucial component in the reduction of violence toward women. In the 1980s, batterer treatment groups often became a mandatory consequence of criminal prosecution, treatment groups proliferated, and their effectiveness was questioned. In the 1990s, the value, form, and success rates of these groups came under scrutiny. This article includes a historical perspective of batterers' intervention programs, a description of the Alternatives to Violence program, and the experiences, perceptions, and opinions of its founder.


A novel type-II InGaN-ZnSnGa2N4 quantum well (QW) structure is proposed based on recent experimental achievements for the successful epitaxy of ZnSnN2-GaN alloys and the determination of their band offsets with GaN. The simulation results indicate that this structure is promising as the active region for high-efficiency InGaN-based amber (λ ∼ 590 nm) light-emitting diodes (LEDs). The hole wavefunction in the valence band is better confined with the insertion of a monolayer scale of ZnSnGa2N4 into the InGaN QW while the electron wavefunction in the conduction band is better confined with the incorporation of an AlGaN layer in the GaN quantum barrier. The band structure of the InGaN-ZnSnGa2N4 QW is numerically simulated based on the experimentally measured band offsets between ZnSnGa2N4 and GaN. With the InGaN-ZnSnGa2N4 QW design, a low In content (20%) is required in the InGaN layer to reach a peak emission wavelength of ∼590 nm, yet an In composition of 25% is needed to reach the same emission wavelength for a conventional InGaN QW with the same layer thicknesses. Moreover, the electron-hole wavefunction overlap (Гe1−hh1) for the InGaN-ZnSnGa2N4 QW design reaches 18% for an emission wavelength at ∼590 nm. This result is much improved over the conventional InGaN QW overlap of 5% emitting at the same wavelength. The increase in electron-hole wavefunction overlap results in an approximately 14 times enhancement in the predicted spontaneous emission radiative recombination rate of the InGaN-ZnSnGa2N4 QW as compared to that of the conventional InGaN QW. This InGaN-ZnSnGa2N4 QW structure design can be promising to pave a new way to achieve high efficiency amber LEDs.

Acinar cell carcinomas (ACCs) are uncommon tumors of the exocrine pancreas, constituting 1% to 2% of all pancreatic neoplasms. They are more common during the 5th through the 7th decades of life. ACCs are defined as carcinomas exhibiting pancreatic enzyme production by neoplastic cells. These tumors have highly characteristic histological features reflecting their acinar derivation. Typically they present as a sizable pancreatic mass with a well-defined enhancing capsule and internal calcification on the image of computed tomography. We report an ACC of pancreas in a 79-year-old female who presented with a 3-cm gastric submucosal mass and a history of anemia initially. The external compression from pancreas exhibited typical acinar morphology. The thickness of peritoneal membrane showed "omental cake" appearance. Immunohistochemical studies demonstrated strong positive reactivity for cytokeratin, polyclonal CEA and antitrypsin. A complete workup identified a primary pancreatic tumor.


Transportation uses a significant amount of energy and burns most of the world's petroleum. As a result, it gives effect to the environment, such as air pollution in the forms of carbon dioxide, nitrous oxide, and particulates. Those compounds create a phenomenon called global warming. Within the transportation sector, road transport is the largest contributor to global warming. To cope with global warming, environmental regulations in developed countries are trying to reduce the individual vehicle's emissions. However, this has been counterbalanced by an increase in the number of vehicles and increased use of each vehicle. Therefore, micro-mobility may alleviate several challenges facing big cities today and offer more sustainable urban transportation. In the next ten years, e-scooter sharing is predicted to become an international business as its potential to become a multi-billion dollar industry (Purnomo Yusgiantoro, 2019). E-scooter sharing has seen a massive leap in popularity within the last few years because, on the surface, it appears to be a business model that is here to stay and, most importantly, has become a solution in creating a greener environment and economy. This research utilizes the framework of the UTAUT2 to identify and build a quantitative approach to identify factors related to the purchase intention factors of e-scooter sharing. The 200 respondents' field data were collected in Jakarta Metropolitan Area (Jabodetabek) as a rapid increase in pollution level and a considerable number of essentials of the central business district and many high-rises stores and universities. The linear regression study revealed that the consumers' purchase intention of e-scooter sharing is shaped by seven main factors: performance expectancy, effort expectancy, social influence, facilitating condition, hedonic motivation, price value, and habit. Those factors can explain 83 percent of the field data. Moreover, a brief recommendation for related stakeholders based on the Research results are proposed to increase the adoption of e-scooter sharing. The practical implications resulting from this analysis are suggested policy measures, e-scooter sharing, environmentally impact potency and strengthening green economy achievement in the communities. Keywords : E-Scooter Sharing, Green Economy, Linear Regression, Purchase Intention

A central issue in the physics of iron-based superconductivity concerns the origin of the pairing interaction, in which the importance of the spin and orbital degrees of freedoms has been discussed. Clarifying the anomalies inherent to this system and unveiling their connections to the high-temperature superconductivity are of primary importance. Here, we report our investigations on clean single crystals of BaFe2(As1−xPx)2 [1]. The observed quantum critical point (QCP) behaviors as represented by non-Fermi liquid transport [1], effective mass enhancement [2], and a sharp peak in the zero-temperature magnetic penetration depth [3] at a critical doping are discussed. In addition, we discuss the development of electronic nematicity, a unidirectional self organized state which breaks the underlying crystal lattice symmetry. Our highly sensitive magnetic anisotropy measurements, together with high resolution synchrotron X-ray diffraction experiments, indicate that electronic nematicity develops in the normal state, far above the magneto-structural and superconducting transitions, resulting in a new phase diagram of iron-based superconductors. The development of electronic nematicity appears to help the emergence of superconductivity whilst the QCP provides the highest superconducting transition temperature.


Replay attack is vulnerable to automatic speaker verification system, where the frauds get the access by replaying the pre-recorded speech utterances of the genuine speakers. In this proposed work, we mainly concentrated on high frequency band and classification part. This paper shows the importance of higher frequency band (6 kHz to 8 kHz). The huge difference between genuine and spoofed speech spectrum is also explained which is caused due to imperfection occurred by using multiple anti-aliasing filters. Alongside, Constant-Q Cepstral Coefficients (CQCC) technique is used to extract magnitude discrimination power features set to detect the replayed spoof attack for speaker verification. Further the ELM based BiLSTM is proposed to improve the system performance. The proposed framework shows better results of Equal Error Rate (EER) to 05.26% for development set and 8.44% for evaluation set.

Original Research Article The sanitary conditions of restaurants and food handling practices if not addressed with seriousness in accordance with international standard practices can be a means of transmitting food-borne infections or intoxications to the public. A study was carried out between December, 2017 and January, 2018 to assess the sanitary conditions, food handling practices of food handlers and the microbial quality of food contact surfaces of selected restaurants in Bauchi metropolis. A total of fourteen (14) restaurants were randomly selected, seven (7) registered with the appropriate authority while seven (7) not unregistered ones. One hundred (100) pre-tested structured questionnaires were equally administered to randomly selected staff of the restaurants. Thirty (30) swab samples of food contact surfaces (spoons and plates) were collected, packed on ice pack and transported to the National Veterinary Research Institute (NVRI) diagnostic laboratory, Bauchi office for analysis. Results of the study showed that majority of the food handlers (n=37; 75.5%) in the registered restaurants were aged 21–35 years, and (n=35; 71.4%) have attained tertiary education while majority (n=38; 77.5%) of the respondents have worked for 1–10 years. While in the non-registered restaurants majority of the food handlers (n=36; 73.5%) were aged 21–35 years, and (n=25; 51.0%) have attained tertiary education and (n=36; 73.5%) of the respondents have worked for 1–10 years. The sanitation and personnel hygiene of most restaurants were observed to be 100% effective with good toilet facilities available. It was also observed that 49.0% of the female workers covers their hairs, 83.7% wears gowns during operations while 59.2% trim their finger nails on weekly basis. Three bacterial organisms (Escherichia coli, streptococcus and staphylococcus) were isolated from the SSFCS with an overall 65% isolation rate. The study also indicated majority (73.4%) have undergone training on food hygiene and handling, and that a large number (89.8%) have heard of food borne diseases. The study showed no much difference in the isolation rate of microorganisms between spoons and plates as well as between registered and non-registered restaurants. And the Sanitary conditions of our restaurants must be improved by enforcing certain measures towards preventing the occurrence of food-borne diseases.


Mobile agents are a useful paradigm – other than a useful technology – for the development of complex Internet applications. However, the effective development of mobile agent applications requires suitable models and infrastructures. This paper proposes an organizational approach to the high-level design of mobile agent applications. The idea is to models the Internet as a multiplicity of local and active organizational contexts, intended as the places where coordination activities of application agents occur and are ruled. The paper discusses the advantages and the generality of such an approach, also with the help of a case study in the area of tourist assistance.


Nowadays, Cloud Computing is the first choice of every IT organization because of its scalable and flexible nature. However, the security and privacy is a major concern in its success because of its open and distributed architecture that is open for intruders. Intrusion Detection System (IDS) is the most commonly used mechanism to detect various attacks on cloud. This paper shares an overview of different intrusions in cloud. Then, we analyze some existing cloud based intrusion detection systems with respect to their various types, positioning, detection time, detection techniques, data source and attacks. The analysis also provides limitations of each technique to determine whether they fulfill the security needs of cloud computing environment or not. We highlight the deployment of IDS that uses multiple detection methods to manage with security challenges in cloud.


In our day, problems pertaining to the methodology of economic forecasting have acquired extremely great importance. This is connected, first, with work on long-range forecasts of the development of the national economy of the USSR (a number of scientific research institutions are already engaged in such research), and, second, with the determination of the prospects for economic competition between our country and the United States, as well as other leading capitalist countries, and with the compilation of a substantiated forecast of future growth of the capitalist economy for these purposes.


The objective of this study was to evaluate the prevalence of the estrogen receptor 1 (ESR1) gene variants and their possible association with coronary artery disease (CAD) in Şanliurfa province. Materials and methods: We used polymerase chain reaction and restriction enzyme digestion to determine the prevalence of the ESR1 gene (NM001122742.1, GI: 2099): c.454-351 A>G (XbaI A>G) and c.454-397 T>C (PvuII T>C) polymorphisms in 100 healthy individuals and 80 angiographically confirmed CAD patients. Results: The body mass index (28.1 ± 5.4), low-density lipoprotein cholesterol (126.1 ± 42 mg/dL), diabetes (n = 13), and hypertension (n = 39) values of the CAD patients were significantly higher than in the control subjects (26.2 ± 3.9, 106.1 ± 26.3, 2, and 18, respectively) (P G and c.454-397 T>C genotype of the ESR1 gene in CAD patients compared to healthy individuals (P > 0.05). Conclusion: The ESR1 variants tested in this study were not associated with CAD. Therefore, neither of these 2 variants can be considered as an independent risk factor or a predictor for CAD in the studied Turkish population.

The thermal power plants are globally criticized for generating large amount of solid wastes often with a potential environmental impact. The main objective of this study is characterized the CCRs (Coal Combustion Residues) produced by the thermal power plant in the East region of Morocco (Jerada city). On other hand, in order to use this CCRs (fly ash and bottom ash) effectively, it is necessary to study the raw material of which they are trained in all their aspects and to check their behavior in the various employment possibilities. For this purpose, mechanical compressive test on 10x10x10 cm of mortar specimens and chemical test of X-ray on CCRs are performed. We did work on the use of CCRs as an addition in Portland cement. Firstly, compressive tests and chemical requirements were used to evaluate the pozzolanic activity index according to ASTM C618 which is about 89,75%. Indeed, the results of an experimental plan, on compressive strength of the new by-product (10% CCRs and 90% cement), gave a good response of our plan, it's about 24,20 MPa. Secondly, we have added this new by-product with the clay to produce the fired compressed bricks according to a new experimental plan, where we found that the most response of the compressive strength equal to 3,12 MPa, in which a minimum volume of water of 581 cm and a minimum quantity of clay of 50% (by total mass of 1kg), were used. In order to valorize these residues, our results show a good correlation with the ASTM standard and we can use this by-products in bricks manufacture.

Society for Publication of Acta Dermato-Venereologica Acquired lymphangiectasia, also known as lymphangioma circumscriptum, of the vulva is a rare malformation characterized by dilated superficial lymphatic channels within the papillary dermis. Clinical presentation consists of clusters of thin-walled vesicles containing clear to serosanguinous fluid. Occasionally, warty hyperkeratosis may be present, leading to a verrucous appearance. Acquired lymphangiectasia of the vulva may arise in inflammatory conditions, such as Crohn's disease, in the setting of intralymphatic metastases, or following surgery, lymphadenectomy or radiotherapy. Symptoms, including pain, frequent drainage and recurrent infections, may motivate patients to seek treatment. Numerous therapeutic modalities have been utilized, including surgery, electrocautery, cryosurgery, and laser resurfacing. However, there is a lack of consensus regarding the optimal treatment approach. We report here a case of acquired lymphangiectasia of the vulva that was treated successfully with 1% polidocanol sclerotherapy.

To test the validity of subspecies designations of the white tern, genetic and morphological data were used to assess differences among four putative Pacific subspecies Gygis alba candida, Gygis alba rothschildi, Gygis alba pacifica, and Gygis alba microrhyncha. The origin(s) of a recent colonization of Oahu was also examined using molecular data. Samples were collected from 209 birds, representing island groups of the North and South Pacific. Culmen length and depth, longest and shortest rectrix lengths, and wing chord measurements from an earlier dataset were compared. Mitochondrial DNA variation suggests that there are no phylogenetically distinct species within the Pacific Ocean. The genetic and morphological similarity of G. a. candida and G. a. rothschildi warrants merging them into one subspecies (G. a. candida). Gygis alba microrhyncha and G. a. pacifica are distinctly smaller and larger than the other two subspecies, respectively, but are not completely diagnosable across the morphological characters examined. Although the Pacific subspecies do not exhibit reciprocal monophyly, there is significant genetic differentiation among the two South Pacific groups, G. a. microrhyncha, G. a. pacifica, and all other Pacific subspecies. This differentiation warrants treating these two South Pacific groups as separate management units, but not species or subspecies. Finally, the recently established population of white terns on Oahu shared haplotypes with all subspecies, suggesting multiple origins from populations across the Pacific and confirming contemporary gene flow. © 2009 The Linnean Society of London, Biological Journal of the Linnean Society, 2009, 98, 586–595.


Based on the study of figures relating to fiscal control, fiscal responsibility and insurance contracts, an analysis is made on fiscal risk coverage in the insurance contracts currently offered by insurance companies, management and compliance for the public sector and the civil liability of public officials, deeming it insufficient, because they have been designed taking into account the public officials, excluding private individuals in charge of fiscal management, or extending coverage on the contractor's fiscal responsibility. This is why it is necessary to create a policy for fiscal management that is specific to the asset impairment that may affect the State due to the wrongdoings (malicious or gravely negligent) of the person in charge of fiscal management, be it a public official or a private individual. The last chapter called Procedural Aspects of the Insurance Relation in the Fiscal Responsibility Process, addresses a few of the most significant judicial figures applicable to any insurance claim, which guide the path of the legal insurance relation.

Abstract It is frequently observed that bamboo particle composites (BPCs) do not show higher mechanical performances than the corresponding wood particles composites (WPCs), although bulk bamboo is much stronger than wood in mechanical performances. Herein this phenomenon was demonstrated from the cell compositions in the applied bamboo particles. To address that, a simple method to physically separate bamboo fibers (BFs) and bamboo parenchyma cells (BPs) from a bamboo particle mixture was developed. Polypropylene (PP) composites with pure BFs, BPs, a mixture of BFs and BPs (BFs + BPs), wood particles (WPs) as fillers were prepared. The flexural and dynamic mechanical properties, water absorption, and thermal properties were determined. The BF/PP composites showed the best mechanical performances (MOR at 35 MPa, MOE at 2.4 GPa), followed by WP/PP, (BF + BP)/PP, and BP/PP. They also exhibited the lowest water absorption and thickness swelling. Little difference was found for the thermal decomposition properties. However, a lower activation energy of BF/PP compared with BP/PP implied an uneven dispersion of BFs and weaker interfacial interaction between BF and PP. The results suggest that the mechanical performances and water resistance of bamboo particle/polymer composites can be significantly improved through cell separation. However, interface modification should be applied if higher performances of BF/PP composites are required.


── Based on ISO 9001: 2015 clause 6.1 CV.Bearpath must consider the risks in producing mountain shoes, so as to minimize and reduce the impact of these risks, and can determine the mitigation measures in advance.

The aim of this study is to describe the reasons of conflict in schools and how it is managed based on a case study. The research was carried out in a school in Manisa. Subjects consisted of three teachers in the department of computer, one vice principal and a principal. The case study method was used and participant observer type of monitoring was applied to collect data. The story of the case study was written based on the data obtained through observations. The case study was analyzed based on the data related to the conflict obtained through literature review. The basic findings of this study are as follows: The conflict in the organization is natural, the conflict at the department of computer is due to the limited resources, the ambiguity in sharing the duties at the department; lack of communication and power struggle. It could be concluded that managers should learn how to manage the conflict instead of ignoring it.


In June 2006 the National Monetary Council is going to define the inflation targetto 2008. That is why it is important to try to preview what the inflation behaviorcould be in 2006 and 2007. The results suggest that it will not be easy to accomplishstrictly the inflation target (4.5%) in 2007 considering a depreciation scenario of thereal compared to the dollar (moderate or higher) at the same time that the interestrates continue to decrease. Therefore it is suggested that the National MonetaryCouncil defines the inflation target for 2008 again in 4.5% in its June 2006 meetingkeeping the target of 2007 also to 2008. Furthermore it is clear that to make itpossible to combine persistent lower inflation rates with higher economic growthrates than the mean of the last 25 years, it is necessary to increase the potential outputgrowth rate.


The production of apparent coal-derived, water-soluble products occurs when certain microorganisms are cultured in the presence of low-ranked coal. The potential utility of these organisms to convert coal to useful liquid products is being investigated. Particular emphasis is being placed on determining the operating parameters that affect liquefaction, on establishing the characteristics of the liquid products, and on studying potential process approaches that could be used for large-scale operation. Various fungi appear to be the most active organisms and several species have been found associated with lignite in the natural state. Lower-ranked coals seem to be better substrates, although biological action on one subbituminous coal was observed. Liquefaction rate appears to be related to the oxidation state of the coal, as well as other chemical characteristics. The liquid product is not well defined, but it includes a large number of soluble molecular constituents, some of which may have moderate to high molecular weights. Most work has been carried out with surface cultures; however, several different types of organisms can be induced to attach to the solid surface of coal when in suspension culture. The latter may represent the mode of operation for a large processing system. 9 refs., 7 figs.,more » 5 tabs.« less


The review covers some issues related to the role of auxiliary components of pharmaceutical preparations. It is emphasized that these components must be studied in many respects before the development of a new pharmaceutical product, including the compliance with the production standards, their influence on the physical, pharmacological, and microbiological characteristics of the final product; the impact on the therapeutic efficacy and safety of a parent drug (i.e., the drug release, bioavailability, etc.). The aspects studied in this article lead to a conclusion that a complex approach is required for the correct assessment of the role of auxiliary components in ensuring the pharmaceutical and therapeutic properties of drugs.

Background: There is limited evidence on the relationship between anxiety and cognition in stroke patients, and no precise relationship between the two has been indicated.

Objective: We aimed to explore the precise relationship between anxiety and cognition in Chinese stroke patients.

Methods: This study was a cross-sectional study, 384 hospitalized stroke patients were assessed with questionnaires and scales, including the Demographic Characteristics Questionnaire, the Hamilton Anxiety Inventory (HAMA), and the Montreal Cognitive Assessment (MoCA).

Results: Anxiety was present in 55.47% of the 384 patients. Univariate analysis showed that age, gender, marital status, smoking, and alcohol consumption were associated with cognition, and multiple linear regression results showed that HAMA was not independently associated with MoCA after adjusting for potential confounders (β=-0.16, 95% CI: -0.29 to- 0.03), which would be inconsistent with HAMA (subgroup) as a categorical variable (P trend of 0.004) A non-linear relationship was detected between HAMA and MoCA with an inflection point of 9. The effect sizes and confidence intervals to the left and right of the inflection point were -0.54 (-0.78 to -0.30) and 0.02 (-0.14 to -0.17), respectively.

Conclusion: The relationship between anxiety and cognition is nonlinear. When the HAMA score is less than 9, anxiety and cognition are negatively correlated, and when it is greater than or equal to 9, the cognitive score will no longer decrease and is saturated.


In the mid-fourteenth century, the authorities of Florence resolved to establish registers of all the real properties within the Florentine dominion. A project, unprecedented in the Florentine history, to record and compile an inventory of estates was conceived. The article considers the circumstances behind the project, primarily the socioeconomic and political factors that drove the authorities' decision. Details are discussed regarding the selection of officials responsible for the project and the work they did. Analysis of the project in question enables to address certain specific issues of late medieval perception and rationalisation of urban and off-urban space.

This paper looks into the implementation of the interdisciplinary curriculum in Algerian EFL course from the perspectives of both broad areas of learning and learning process. It analyses two textbooks, Spotlight on English Book 3 and Getting Through, belonging respectively to the middle and secondary school levels. The analysis shows that the designers have adopted the Interpretation, Constructivist Design (ICON) Model (O'Mallet and Chamot 1990) and restricted its use to the strategy of generating and testing hypotheses. Our main findings underscore the constructivist orientation of the curriculum and underline three important flaws in the textbooks: one, the activities are not purposive in questioning for information and cooperation; two, the generating strategy serves as a learning strategy rather than as a learning process; three, the stages of multiple interpretations and manifestations are rarely attained, leaving little opportunity for knowledge transfer to real life contexts.

The article proposes a conceptual framework for analyzing the key drivers for retailers' transport demand more systematically. Certainly, a better understanding of the reasons behind the growth in transport demand is crucial in formulating effective measures to manage and reduce emissions. Regarding to retailer-led supply chains, analyzing the retailers' transport demand and its key drivers seems to be indispensable. This issue is even more important on an urban scale as retailers have a high share of urban freight transport. The authors' main assumption is that retailers' transport strategies are dependent to non-transport-related context, both internally to the non-transport strategies and also externally to the company's environment. A classification of the context in three layers is suggested: The macro-context represents retailers' upstream context which includes the competitive and regulatory framework of retail industry, as well as consumers' consumption patterns. The meso context refers to the retailer's sectorial dynamic. It includes aspects such as the vertical integration of distribution of wholesale stage or new relationships with suppliers e.g. through the development of own-brand products. The micro context is related to the strategy of the individual retailer and encompasses economic strategies (type of retail format, marketing area etc.). Furthermore, the paper illustrates the chains of interdependencies between different layers of context and their consequences for logistics and transport organization, using the example of food retailers in France and Germany. As one result, the influence of retailers' sales related strategies on logistics and transport can be demonstrated.


This case follows Kaycee, who had just returned two weeks ago from a 27-month stay in prison, as she discovers that she is the victim of identity theft. To find out what steps to take, Kaycee reaches out for advice to Marisa Berryman, a mentor at the residential facility that housed Kaycee for three months following her incarceration before she returned home. The goal of this case is to educate students about the risks of identity theft, teach them how best to protect themselves, and inform them how to react if their identity has been stolen. The case is designed to be taught in a financial literacy course for non-MBA audiences.

Introduction

Kaycee smiled as she sat in the coffee shop and sipped her morning coffee. It was worth the stress of catching her first bus of the day. She closed her eyes and was seven again, sitting in front of the picture window in the living room and sipping a cup of hot chocolate. Life and the beauty of the simple things chocolate on her lips, the sun on her face, gooey marshmallows had warmed her heart. If I had known then what I know now, she thought as she opened her eyes again.

She knew that this moment of peace would be interrupted soon, because it was almost time to catch the second bus of the day the one that took her to work. Later tonight she would catch her third bus of the day. Even though her total commute home to coffee shop, coffee shop to work, and work to home was probably less than five miles, it took three hours every day. Much of it was dead time waiting for buses to arrive, and transferring from one bus to another. But this was what Kaycee's life was like because she had no driver's license and no car.

Health structures are increasingly facing changing health demands and economical and political pressure. Recent studies are dealing with these issues and provide promising alternatives to traditional Health Care Systems: • Home Health Care (HHC) to provide continuous and coordinated care services at the patients' home, which is particularly efficient in aging societies; • Lean Heath Care which applies lean management principles that have been used effectively in manufacturing companies for decades, to health care delivery systems; • Health care systems planning and optimization provide optimal solutions for planning and resource allocation problems using algorithms from Operations research and artificial intelligence; • Uncertainty and Decisional support systems in Health Care to provide support for healthcare managers to help them make the best decisions when perturbations occur. The objective of this session is to discuss health care systems and new and efficient decisional and optimisation techniques to improve healthcare services. Topics: • Home Heath care; • Lean HealthCare; • Capacity planning; • Day surgery (ambulatory surgery); • Logistical supports; • Reverse logistics; • Emergency.


Stage on Screen is a new company that is working in partnership with Greenwich Theatre in order to perform and record classic set texts, which appear on the English, Theatre Studies and Drama GCSE and A Level syllabuses. The company provide a teaching package that includes four discs: the main DVD of the play and an extras DVD which includes interviews with members of the cast, the director and the designers. As well as this, there are also an interactive CD-ROM and a Mastershot DVD, which is the play shown from a single camera in a fixed position. The aim of the company is to try to enable schools and colleges that are not within easy reach of a theatre to get a chance to experience the texts they are studying in performance. This is clearly a very admirable undertaking and Elizabeth Freestone directed a largely faithful production of the A-text of Christopher Marlowe's Doctor Faustus. The design of the Greenwich theatre is based on an amphitheatre. The stage is circular and the seats in the 400-capacity auditorium arc in a semi-circle round the front of the stage and rise away towards the back. For this production there were two walkways that connected the stage with the audience. This was, presumably, to create a sense of intimacy as well as for practical reasons. However, the general amphitheatre design did not lend itself to a particularly intimate theatrical experience. The action unfolded against the semi-circular, permanent set of Faustus's study. There was also an upper gallery on top of the semi-circular set on which characters appeared from time to time. The design of the production was vaguely nineteenth-century with many of the characters wearing suits with open-neck shirts with large collars and cuffs. However, other than the big shirts there was nothing definitely nineteenth-century and there appeared to be no concerted effort to root the play in that particular time period, so the idea came over as somewhat half-baked. As the audience entered the auditorium they were greeted by the sound of a howling wind and the sight of a dimly lit set, which was shrouded with a thin cloud of smoke. After the Chorus's introduction, Freestone did depart from the text slightly and had the ensemble company clamour around Faustus to try to persuade him to take up law, philosophy, religion or physic. Faustus quickly dismissed the noisy mob and the production returned to Marlowe's words as Faustus delivered his opening monologue. Other than this, the A-text was adhered to throughout. One of the problems facing any company that wishes to produce the complete text of Marlowe's play is that the story is very episodic. After the wonderfully


An defoliation epidemic by Ascotis selenaria imparata (Lepidoptera : Geometridae) started in the Sal forests of Mohammadpur Block of Asarori Range, West Dehra Dun Division in early 1975. Compartments 4, 5 and 6 were affected. In compartments 4 and 5 complete defoliation of Sal trees occurred whereas in compartment 6 trees were partially defoliated. In the understorey, trees of Mallotus philippinensis and Murraya koenigii were also badly defoliated. Two generations of the defoliator were completed by June-July, 1975 and a third generation started in the month of July. However the third generation larvae got completely annihilated by the infection of a nuclear polyhedrosis virus and the epidemic came to an abrupt end. Observations on the biology and natural enemy complex of the pest and the resultant impact of defoliation epidemic on Sal trees have been made. Control measures using insecticides and pathogens have also been suggested.

Toxoplasma gondii, an apicomplexan parasite of mammals and birds, is well recognized as a cause of encephalitis in AIDS patients and as a cause of congenital infections. The polymerase chain reaction (PCR) and toxoplasma cDNA clones were used to diagnose T. gondii infection in an acute murine model of toxoplasmosis. Diagnosis of tissue infection by Southern blot hybridization with cDNA clones of T. gondii was possible within 5 days of infection. This technique could detect as few as 10,000 organisms. Specific T. gondii gene amplification by PCR using the primers 5'CACACGGTTGTATGTCGGTTTCGCT3' and 5'TCAAGGAGCTCAATGTTACAGCCT3' followed by oligonucleotide hybridization using 5'GCGGTCATTCTCACACCGACGGAGAACCACTTCACTCTCA3' allowed detection of T. gondii in the tissue of mice by day 2 after infection and in the blood of mice by day 5 after infection with RH strain T. gondii. This technique could detect as few as 10 organisms. Thus, these techniques may be useful in the diagnosis of toxoplasmosis.


We propose and evaluate a novel device based on integration of quantum well infrared photodetector (QWIP), heterostructure bipolar transistor (HBT), and light emitting diode (LED) for up-conversion of middle infrared into near infrared (visible) radiation. Its operation is associated with intersubband absorption of middle infrared radiation in the QWIP, amplification of the QWIP output electric signal in the HBT and emission of near infrared or visible radiation from the LED driven by the current injected from the HBT. The integrated QWIP-HBT-LED device can serve as a highly effective pixel for infrared focal plane arrays.


IQ tests work only for some people some of the time. This assertion is an inescapable conclusion of the fact that "it is unusual for a validity coefficient to rise above .60, though that is far from perfect prediction" (Cronbach, 1970, p. 135). This situation has not really changed over many years: In reviewing the literature on test validities, Ghiselli (1966) found validities had changed little over the years in which aptitude tests had been used as predictors of academic and job performance. And the value of .60 is


Abstract : The magnetic flux and the inductance due to the current passing through a plasma armature in an electromagnetic launcher is evaluated assuming that the current distribution within the armature is uniform. The expressions derived in this report are then used by the computer program PLAFLUX.FOR to generate values for the plasma armatures inductance and magnetic flux during acceleration. It is shown that the plasma armature's inductance is negligible in comparison with the rail inductance.

Load balancing is the process of improving the Performance of a parallel and distributed system through is distribution of load among the processors(1-2). Most of the previous work in load balancing and distributed decision making in general, do not effectively take into account the uncertainty and inconsistency in state information but in fuzzy logic, we have advantage of using crisps inputs. In this paper, we present a new approach for implementing dynamic load balancing algorithm with fuzzy logic, which can face to uncertainty and inconsistency of previous algorithms, further more our algorithm shows better response time than round robin and randomize algorithm respectively 30.84% and 45.45%.


On receipt of news of the Fleischmann-Pons announcement in March 1989, scientists loaded samples of Pd and Ti metal with deuterium using both electrolytic methods and gas/plasma- based absorption techniques. Twelve research groups and 50 scientists were involved in this massive effort. Clear evidence was accumulated for the generation of neutrons and tritium. Not only was the rate of neutron emission measured, but also, in some cases, a sophisticated analysis of the stastistical characteristics of neutron emission was carried out. The most important findings were: (a) Tritium production is much more probable than neutrons, with the neutron to tritium yield ratio being ~ 10 -7 ; (b) A fraction of the neutrons released is in the form of bursts of tens to hundreds of simultaneously emitted neutrons; and (c) The nuclear reactions responsible for the production of these seem to be occurring in highly localized hot spots in the host metal. These results strongly suggest the possible occurrence of some type of micro-nuclear explosions in selected lattice sites.


We argue that the detection of neutrino signature from the Earth's core can effectively probe the coupling of heavy dark matter ($m_{\chi}>10^{4}$ GeV) to nucleons. We first note that direct searches for dark matter (DM) in such a mass range provide much less stringent constraint than the constraint provided by such searches for $m_{\chi}\sim 100$ GeV. Furthermore the energies of neutrinos arising from DM annihilation inside the Sun cannot exceed a few TeVs at the Sun surface due to the attenuation effect. Therefore the sensitivity to the heavy DM coupling is lost. Finally, the detection of neutrino signature from galactic halo can only probe DM annihilation cross sections. We present neutrino event rates in IceCube and KM3NeT arising from the neutrino flux produced by annihilation of Earth-captured DM heavier than $10^{4}$ GeV. The IceCube and KM3NeT sensitivities to spin independent DM-proton scattering cross section $\sigma_{\chi p}$ in this mass range are presented for both isospin symmetric and isospin violating cases.


Background: Titanium dioxide nanoparticles (TiO2 NPs) were healthy well-known as a photocatalyst and it was extensively utilized for photocatalysed corrosion, sensor essentials, water distillation and had numerous other submission. Also, in food industry. However they also had poisonous result on animals uncovered to them. Objectives: we examined the probable ameliorative result for the two flavonoids morin and rutin which had apotent antioxidant activity, against TiO2 nanoparticles-induced toxicities in rat liver. Materials and methods: Albino rats (n =70, weight 150-200g) were divided into seven groups. Group (G1) (control), G2 (treated with morin 30 mg/kg), G3 (treated with rutin 80 mg/kg), G4 (toxic group that administrated orally with titanium dioxide nanoparticles 100 mg/kg), G5 (TiO2 NPs+ morin), G6 (TiO2 NPs+ rutin), G7 (TiO2 NPs+ morin+ rutin). The evaluated parameters included liver function markers, some minerals and electrolytes, antioxidant (superoxide dismutase SOD, catalase CAT and glutathione GSH) and oxidative stress malondialdehyde (MDA) biomarkers in addition to DNA fragmentation and histopathological examination of liver tissues. Results: These experimental study showed that a significant increase of  serum ALT, AST, ALP activities. Also, serum potassium (K) and phosphorous (P) levels, hepatic MDA content, comet, tail length, DNA in tail and tail moment of DNA fragmentation were detected in TiO2 NPs (G4) group indicating liver damage which compared with control group (G1) but  this parameters decreased significantly in morin (G5) or rutin (G6) when compared with toxic group (G4), in combination group (TiO2 NPs+ morin+ rutin) (G7) succeeded to decrease significantly in this parameters and returns to (G1). Also, our results showed that a significant decrease in total protein, albumin, sodium (Na), calcium (Ca) levels, glutathione (GSH) level, superoxide dismutase (SOD) and catalase (CAT) activities in toxic groups (G4) but succeeded to increase significantly in this parameters in G5, G6 and G7 in compared with control group and restore it. Conclusion: TiO2NPs oral administration induced toxic effects and DNA damage in the liver that may be attributable to oxidative stress.Also, administration of morin and/or rutin with TiO2NPs offers protection against their damaging effect.


BACKGROUND: Data smoothing of vital signs has been reported in the anesthesia literature, suggesting that clinical staff are biased toward measurements of normal physiology. However, these findings may be partially explained by clinicians interpolating spurious values from noisy signals and by the undersampling of physiological changes by infrequent manual observations. We explored the phenomenon of data smoothing using a method robust to these effects in a large postoperative dataset including respiratory rate, heart rate, and oxygen saturation (SpO2). We also assessed whether the presence of the vital sign taker creates an arousal effect. METHODS: Study data came from a UK upper gastrointestinal postoperative ward (May 2009 to December 2013). We compared manually recorded vital sign data with contemporaneous continuous data recorded from monitoring equipment. We proposed that data smoothing increases differences between vital sign sources as vital sign abnormality increases. The primary assessment method was a mixed-effects model relating continuous-manual differences to vital sign values, adjusting for repeated measurements. We tested the regression slope significance and predicted the continuous-manual difference at clinically important vital sign values. We calculated limits of agreement (LoA) between vital sign sources using the Bland–Altman method, adjusting for repeated measures. Similarly, we assessed whether the vital sign taker affected vital signs, comparing continuous data before and during manual recording. RESULTS: From 407 study patients, 271 had contemporaneous continuous and manual recordings, allowing 3740 respiratory rate, 3844 heart rate, and 3896 SpO2 paired measurements for analysis. For the model relating continuous-manual differences to continuous-manual average vital sign values, the regression slope (95% confidence interval) was 0.04 (−0.01 to 0.10; P = .11) for respiratory rate, 0.04 (−0.01 to 0.09; P = .11) for heart rate, and 0.10 (0.07–0.14; P < .001) for SpO2. For SpO2 measurements of 91%, the model predicted a continuous-manual difference (95% confidence interval) of −0.88% (−1.17% to −0.60%). The bias (LoA) between measurement sources was −0.74 (−7.80 to 6.32) breaths/min for respiratory rate, −1.13 (−17.4 to 15.1) beats/min for heart rate, and −0.25% (−3.35% to 2.84%) for SpO2. The bias (LoA) between continuous data before and during manual observation was −0.57 (−5.63 to 4.48) breaths/min for respiratory rate, −0.71 (−10.2 to 8.73) beats/min for heart rate, and −0.07% (−2.67% to 2.54%) for SpO2. CONCLUSIONS: We found no evidence of data smoothing for heart rate and respiratory rate measurements. Although an effect exists for SpO2 measurements, it was not clinically significant. The wide LoAs between continuous and manually recorded vital signs would commonly result in different early warning scores, impacting clinical care. There was no evidence of an arousal effect caused by the vital sign taker.

Ion-pairing liquid chromatographic method was validated for determination of ketoconazole in shampoo and cream samples as per ICH guidelines. The chromatographic conditions were carried out in the isocratic mode using a mixture of methanol and 8 mM sodium dodecyl sulfate (pH 5.5) in a ratio of 45:55 v/v %, as mobile phase. The flow rate was set at 1.0 mL min-1. Chromolith RP-18e (100×4.6 mm) was used as the analytical column with a fluorescence detection at an excitation wavelength of 260 nm and an emission wavelength of 375 nm. The average percentage recovery of shampoo A, shampoo B, shampoo C, cream A and cream B were 99.88, 97.06, 99.58, 96.77 and 97.26, respectively. The limit of detection was 0.12 mg L-1. The drug decomposition under acid degradation, base degradation and oxidative degradation were found to be in the range of 91.63-94.70% indicating that the drug is resistant towards acidic conditions. The drug decomposition under thermal condition and photolysis condition were found to be in the range of 69.05-87.15% and 47.31-66.83% respectively, indicating that the drug decomposition is more sensitive under photolysis conditions. This method is suitable for the quality control of ketoconazole in commercial shampoo and creams.
