A novel DC transmission system using a new type of converter transformer is proposed and its topology is analyzed. Focus of discussion in the paper is the influence of the level of reactive power compensation on the operation of DC transmission system, when the corner delta windings of the new type of converter transformer are connected with the filtering and reactive-load compensation equipment on the valve side. Through statistical analysis on the variations of the commutating resistance of the new type of converter transformer at different levels of reactive power compensation, the characteristic curves of commutating angle, DC voltage, and the converter's reactive power characteristic are obtained, so that the operating characteristics of the novel DC transmission system influenced by the level of reactive power compensation are analyzed. The analytical results show the superiority of the new system with the new type of converter transformer.


We report recent progress on the diamond amplified photo-cathode (DAP). The use of a pulsed electron gun provides detailed information about the DAP physics. The secondary electron gain has been measured under various electric fields. We have achieved gains of a few hundred in the transmission mode and observed evidence of emission of electrons from the surface. A model based on recombination of electrons and holes during generation well describes the field dependence of the gain. The emittance measurement system for the DAP has been designed, constructed and is ready for use. The capsule design of the DAP is also being studied in parallel.


The invention relates to an axial switching type target and multi-sky-area location star map simulator. The simulator comprises a five-axis turntable, a mounting flange, an axial channel switching platform, an optical projection system, a beam combiner, a simulation panel, a liquid crystal star map scene simulator and a control unit. When the spatial position and energy change of the star map and target are dynamically and really simulated, meanwhile, the weight of the complete unit is lightened, the structure is compact, and the switching speed of the target and multi-sky-area location star map simulator is high.


Previous studies have indicated heart sounds contain information for the detection of partially occluded coronary arteries. In this study, recordings of diastolic heart sound segments were analyzed by using three advanced signal processing techniques; the Autoregressive (AR), the Autoregressive Moving Average (ARMA), and the Minimum-Norm (Eigenvector) methods. In order to enhance the diastolic heart sounds and eliminate background noise, the Adaptive Line Enhancer (ALE) method was used as a preprocessor. These advanced signal processing techniques were used to estimate the model parameters. The poles of the AR, ARMA and Minimum-Norm methods were used to diagnose patients as diseased or normal-Results showed that normal and abnormal records were correctly identified in 32 of 38 (36 patient) cases.


The functionalization of AuNPs with different biological elements was achieved to investigate their possibility in biomedical applications such as drug delivery, vaccine development, sensing, and imaging. Biofunctionalized AuNPs are pursued for applications such as drug delivery, vaccine development, sensing, and imaging. In this study, AuNPs with diameters of 20 nm were functionalized with lipoic acid, mannose, or the cRGD peptide. By using UV-vis spectroscopy, Fourier transform infrared spectroscopy, dynamic light scattering, transmission electron microscopy, and scanning tunneling microscopy techniques, we showed that AuNPs can be functionalized by these biomolecules in a reliable way to obtain conjugates to explore potential biomedical applications. In particular, we demonstrate that the STM technique can be employed to analyze biofunctionalized AuNPs, and the obtained information can be valuable in the design of biomedical applications.


In most developed countries urban mobility and car traffic have stagnated since the early 2000s. In France, various data sources show that the trend can be attributed primarily to people living in large urban areas: trips have become less frequent (with unbroken workdays) and less exclusively taken by car (as more young adults adopt multimodal behaviours), and car ownership is decreasing in denser areas, and to a lesser extent, in suburbs. Does this levelling-off of traffic suggest that the saturation point is near? Is this a structural phenomenon (population ageing, etc.) or a cyclical one linked to rising and volatile fuel prices and the recession? We shall explore these issues in the light of data collected in the Urban Areas of Montreal and Lille, and then move on to a comparison with two Mexican cities, Ciudad Juarez on the northern border of Mexico where the level of motorization is high compared to Puebla, our second Mexican case study, where motorization is still low. To each city we apply demographic based projections models in order to consider the extent to which, and in what timeframe, the trends observed in developed cities could spread southward to the emerging economies.


This study was conducted to determine the effect of potassium combined with organic fertilizers on the growth, yield and sweetness of reddish waxy corn. The experiment was arranged on Completely Randomized Design (CRD) covering a span of three months. The treatments were: control or 60 kg ha-1 of potassium (Tl), 30 kg ha-1 potassium + 20 tons ha-1 chicken manure biochar + 1.5 tons ha-1 of bokashi (T2), 90 kg ha-1 potassium + 20 tons ha-1 chicken manure biochar + 1.5 tons ha-1 of bokashi (T3) and 120 kg ha-1 potassium + 20 tons ha-1 chicken manure biochar + 1.5 tons ha-1 of bokashi (T4). Each treatment was replicated six times. Stem girth, number of leaves, height of first cob, fresh weight of first cob, 100 grains weight, cob girth, cob length and sweetness of Brix reading was analysed using ANOVA at 5% significant levels. Least Significant Different (LSD) was used to compare the means for significantly different results. Significant differences on growth was obtained at (p<0.05) in waxy corn for the number of leaves, height of first cob, length of cob and girth of between the control and all treatments. However, no significant difference was obtained for sweetness of waxy corn for all treatments. Mean total for growth parameters; number of leaves, stem girth and height of first cob from soil surfaces and mean total for yield parameters; cob girth, length of cob, fresh weight of cob, 100 grains weight and number of kernels was significantly higher for all treatments of T2, T3 and T4 compared to control treatment of Tl. Results of the study showed no significant different on the sweetness of waxy corn with increasing potassium application resulting in increased total soluble content. Similar studies for different rate of organic fertilizers and soil analysis can be done to further ascertain the effects on growth, yield and sweetness parameters of reddish waxy corn with selected soil properties.

Abstract This study focuses on on-line specific fuel consumption (SFC) optimization of aero engines. For solving this optimization problem, a nonlinear pneumatic and thermodynamics model of the aero engine is built and a hybrid optimization technique which is formed by combining the genetic algorithm (GA) and the sequential quadratic programming (SQP) is presented. The ability of standard GA and standard SQP in solving this type of problem is investigated. It has been found that, although the SQP is fast, very little SFC reductions can be obtained. The GA is able to solve the problem well but a lot of computational time is needed. The presented hybrid GA-SQP gives a good SFC optimization effect and saves 76.6% computational time when compared to the standard GA. It has been shown that the hybrid GA-SQP is a more effective and higher real-time method for SFC on-line optimization of the aero engine.


Slope of the characteristic curve drawn from measurements of a narrow-lined spectrum is less than that of a curve drawn from broad lines or from continua This is due to. 1) the lateral diffusion of lines within the emulsion, 2) narrow lines being subject to Schwarzschild-Villiger Effect in the densitometer, which particularly tends to change the shape of the toe. (This effect is minimized in dense lines due to diffusion), and 3) the spreading of dense lines, which causes errors in reading background if the area read is too close to the line. Each of the three effects lowers the line-to-background ratio.


Antibody  based  methods  have  numerous  advantages  compared  to  other  detection  methods. However, heavy metals cannot stimulate the immune antibody response; it is the main obstacle for preparation of the antibodies that used in detection methods of the metals. The production of the immunogenic Pb complexes by using cost benefit linkers of EDTA and DTPA were investigated in this  study.BSA  molecules  were  functionalized  using  EDTA  and  DTPA  linkers  in  various BSA/linker ratio, pH, incubation times and buffers. The complexes were formed after addition of the  Pb  to  the  [BSA-linker].  Different  concentrations  of  the  glutaraldehyde  were  mixed  with  the formed  complexes  and  shaken  at  room  temperature  for  12  hours.  The  prepared  conjugates  were dialyzed in phosphate buffer saline for 72 hours. Stimulation of the mice antibody responses against the  prepared  [Pb-linker-BSA]  complex  were  evaluated  using  ELISA.  In  optimized  condition,  the DTPA linker coupled Pb to each BSA molecules 2 times higher than EDTA. The optimum pH was 9.6 in EDTA binding to BSA; also, EDTA molarity was 25 times higher than Pb molarity in [PbEDTA-BSA] complexes.These conditions for DTPA conjugation to Pb and BSA are pH 7.4-9.6 and 9.6 respectively. Also, optimum molarity of DTPA was 4 times higher than Pb in [Pb-DTPABSA] complexes. Also, the higher antibody responses against Pb were stimulated by immunization with an antigenic complex that has more solubility and Pb coupled to each albumin molecules. In conclusion,  in  optimized  conditions,  DTPA more  efficient  than  EDTA  for  synthesizes  of  the immunogenic Pb complex.


Cloud computing is changing the way enterprises, institutions, and people understand, perceive, and use current software systems. Cloud computing is an innovative concept of creating a computer grid using the Internet facilities aiming at the shared use of resources such as computer software and hardware. Cloud-based system architectures provide many advantages in terms of scalability, maintainability, and massive data processing. By means of cloud computing technology, cytopathologists can efficiently manage imaging units by using the latest software and hardware available without having to pay for it at non-affordable prices. Cloud computing systems used by cytopathology departments can function on public, private, hybrid, or community models. Using cloud applications, infrastructure, storage services, and processing power, cytopathology laboratories can avoid huge spending on maintenance of costly applications and on image storage and sharing. Cloud computing allows imaging flexibility and may be used for creating a virtual mobile office. Security and privacy issues have to be addressed in order to ensure Cloud computing wide implementation in the near future. Nowadays, cloud computing is not widely used for the various tasks related to cytopathology; however, there are numerous fields for which it can be applied. The envisioned advantages for the everyday practice in laboratories' workflow and eventually for the patients are significant. This is explored in this chapter.


The development of the innervation of the sensory neuro-epithelium of the inner ear has been studied in organ cultures of the chicken-embryo otocyst and in the developing chicken embryo, with particular reference to the origin of the nerve endings and neurones. It is suggested that they originate from their embryonic centres in the mesenchyinatous tissue surrounding the otocyst, and reach the neuro-epithelial cells through gaps in the otic capsule and the basement membrane.


How to optimize the production mode is always important for manufacturing companies to satisfy the demands of customers. The manufacturer can adopt Make-To-Stock (MTS) mode, i.e. produce products in advance and store them until demands arrive. If the inventory level is adequate, the demands can be satisfied immediately. However, accurate prediction and stable demands are necessary in MTS mode. Otherwise, high inventory cost will become a problem. Make-To-Order (MTO) is another way used around the world. Under the mode of MTO, the products won't be produced until real orders appear which reduces inventory cost but quick response is needed. The DVS Company studied here is making a decision that if it should change its production mode from MTS to MTO. DVS Company is a small company located in Shenzhen city of south China. It produces nearly 150 different products of pipeline fittings such as wire casing and three-way elbow. The company has a 2,200 square meter factory with four floors, one floor for raw materials, one for production equipments and two for finished products. Although a variety of products are produced, the production processes are similar and actually simple. First, raw materials are mixed according to the product type. Secondly, the raw materials are molten and changed into plastic products by injection molding. With different mould, the injection molding machine can produce different product. At present, DVS Company has only one mould for each product. To improve productivity, the mould is designed to produce a batch (usually four or eight same parts) of product instead of a single one per injection molding. As a result, the batch of product needs cutting and packing before delivery. DVS Company currently uses MTS mode to carry out its production plan. It keeps two-week inventory to satisfy the market demands. Though the order number per day is relatively stable (about 10 orders per day), the items and quantities requested by the orders fluctuate frequently. For example, an order consists of 2 items/products and 200 units while another order requests 20 items and 500,000 units. Consequently, high inventory level is necessary to satisfy the stochastic demands, which leads to high inventory cost. Furthermore, overstock becomes more and more serious due to the changing market and customers' preference. Therefore, the DVS Company wants to implement MTO in order to improve its quick response ability. However, many factors should be considered. Obviously, MTO may increase the setup time and cost because of frequent change of mould. Due date of orders is also an important requirement of customers. MTO is more likely to delay the delivery time due to resource constrains (mainly injection molding machine in this case). One-month data including product information such as productivity, price and unit inventory cost, order information such as arrival time, items and quantities, were collected. The period of these data is


This paper is an overview on the research of the field programmable technology,including its category,concept,advantage,key factor and all developmental stages,ect.The key flows and methods of FPGA design are summarized.


Most systematic design procedures for either curricula or courses start from a description of educational goals. These goals are then decomposed into more specific objectives which are categorized according to some taxonomy of learning. The basic idea is that different categories of goals and objectives correspond with different optimal instructional methods. However, for complex intellectual skills a set of subskills is performed. The ability to perform each of those subskills separately does not guarantee that the skills can be coordinated and integrated in performing real-world tasks. This problem is known as the problem of 'integrated goals' or 'multiple objectives'. This paper argues that educational goals and objectives should be seen and treated as highly integrated and interrelated during the whole educational design process. Approaches to dealing with multiple objectives are discussed.


When system components become more coupled over time, more effort must be dedicated to software architecture refactoring. Tightly coupled components present higher risk— they make the system more difficult to understand, test and modify. In order to allocate the refactoring effort effectively, it is crucial to identify how severely components are coupled and which areas of the system involve the most risk to modify. In this paper we apply the concept of architecture hotspots together with the Software Improvement Group Maintainability Model to identify violations in architecture design. We propose a prototype tool that can identify and present architecture smells to developers as refactoring recommendations. We then apply the tool to open-source projects, validating our approach through interviews with developers. Developers found the hotspots comprehensible and relevant, but there is room for improvement with regards to actionability.


Some philosophers argue that the state and its citizens stand in a morally privileged position vis-à-vis one another, but not towards other states or citizens. However, many of those people, particularly philosophical liberals, also hold that morally insignificant differences, such as place of birth, sex or ethnicity, should not affect rights, liberties and life prospects. On the face of it, these two sets of ideas appear incompatible and point to a conflict in some liberal thought. Liberal philosophers, like John Rawls, have attempted to reconcile these conflicting ideas. His attempt has attracted a great deal of criticism, especially from those liberals attracted to a more cosmopolitan point of view. In this article, we use Aristotelian virtue ethics as the basis upon which to reconcile liberalism and patriotism. We argue that the state should be understood as an agent that stands in a special relationship to its citizens (of philia). The state's virtue depends, in part, on it giving those citizens preferential treatment with regard to justice compared to citizens of other countries. Similarly, if citizens are to be just in their relations with their own state, they must behave in special ways towards that state as compared to other states. Certain forms of justice only arise in relationships of particular kinds.


At present, in the inspection of special equipment, the application of the measurement uncertainty of the equipment is not popular. The uncertainty of the inspection and testing data of special equipment must be obtained on the basis of the uncertainty of the equipment. This paper takes the uncertainty of the verification temperature test chamber as an example, and specifies the application of the measurement uncertainty in the inspection and testing equipment.


Forgive my penchant for neologisms and allow me to revel in my virginal thespian experience striding the Hostos Repertory Theatre stage as the ignoble Dr. Fine in " Six Degrees of Separation. " From a primal fear of being deluged by floodlights and upstaged by a talent deficit greater than our national debt, I was inspired by the avatar of the ancient muses and magically transformed into a loving and


A novel olivine LiCoAsO 4 has been successfully synthetized and characterized. This novel compound is electrochemically active at an average voltage of 4.7 V versus a lithium electrode; this is about 0.1 V below the lithium deinsertion voltage of LiCoPO 4 , the general electrochemical characteristic being similar in both materials. Calculations using the local density approximation with the Hubbard U parameter correction method (LDA + U) allow a correct prediction of the insertion voltage confirming that the insertion voltage in CoAsO 4 is some milivolts lower than in CoPO 4 . Calculated results evidence that replacing the (PO 4 ) -3 group for the less covalent (AsO 4 ) -3 group increases the covalency of the Co-O bond and raises up the energy of the Co d states. As a result, the energy of the Co +3 /Co +2 couple gets closer to that of the Li + /Li redox couple and the lithium insertion takes place at a lower voltage. This subtle voltage shift is very beneficial for lithium batteries operating near the limit of the electrolyte decomposition.


Automatic segmentation of anatomical structures is often performed using model-based non-rigid registration methods. These algorithms work well when the images do not contain any large deviations from the normal anatomy. We have previously used such a method to generate patient specific models of hip bones for surgery simulation. The method that was used, the morphon method, registers two-or three-dimensional images using a multi-resolution deformation scheme. A prototype image is iteratively registered to a target image using quadrature filter phase difference to estimate the local displacement. The morphon method has in this work been extended to deal with automatic segmentation of fractured bones. Two features have been added. First, the method is modified such that multiple prototypes (in this case two) can be used. Second, normalised convolution is utilized for the displacement estimation, to guide the registration of the second prototype, based on the result of the registration of the first one.


[Objective] To study the effects of highly active bacterium-fermented feed on immunity and antioxidant activity of growing-finishing pigs and to provide the basis for its promotion and application.[Method] A total of 180 Duroc × Landrace × Yorkshire crossbred growing-finishing pigs were randomly divided into two groups.The pigs in the control group were fed on traditional diet supplemented with antibiotics,and those in the experimental group were fed on traditional diet supplemented with highly active bacterium-fermented feed at a proportion of 8%.[Result] The contents of serum immunoglobulin were higher in the experimental group than in the control group.Particularly,significant difference was found in the content of IgG between these two groups(P0.05).The experimental pigs fed for 28 d had significantly higher blocking rate of antibody against classical swine fever virus than those fed for 21 d(P0.05).The experimental pigs had remarkably stronger antioxidant activity than the control group,and the difference in T-AOC was significant between them(P0.01).[Conclusion] The highly active bacterium-fermented feed enhanced immunity and antioxidant activity of growing-finishing pigs and had a greater application value in production.


Several "e-movement" crusaders have discovered that customers spend significant amounts of time researching products they seek before purchasing. In a bid to assist customers in these efforts, and conserve precious time, these organizations offer users suggestions of products they may be interested in. This serves the dual purpose of not just attracting browsers but converting them into buyers. For instance, an online bookstore may know that a customer has interest in mobile technology based on previous site visits and suggest relevant titles to purchase. An uninitiated user may be impressed by such suggestions. Suggestions (or "recommendations" as they are popularly known) predict likes and dislikes of users. To offer meaningful recommendations to site visitors, these companies need to store huge amounts of data pertaining to different user profiles and their corresponding interests. This eventually culminates in information overload, or difficulty in understanding and making informed decisions. One solution to combating this issue is what is known as a recommendation system.

A compact ultra-wideband (UWB) printed monopole antenna with radial patch is proposed and investigated. In order to achieve better impedance matching over the entire UWB frequency band, the conducting ground is defected. The proposed antenna is very small in size, only 15×15mm. The proposed antenna is fed by a 50 microstrip line. The parameters which affect the operation of the antenna are analysed and optimized values are obtained. The bandwidth of the proposed antenna is 3.4GHz-12.8GHz for return loss less than -10dB, which is about 116% with respect to the center frequency of 8.1GHz. The radiation patterns of the proposed antenna are relatively stable over its operating band and the H-plane patterns are all omnidirectional.

Geostationary communication satellites are a large market for the space utilization domain. From the user's perspective, the commercial communication payload mass is among the most important specification parameters. In order to maximize payload mass and customer satisfaction, the satellite bus mass should be minimized because the launch mass is constrained by launcher vehicle capability. Therefore, electric propulsion offers a practical design option for geostationary communication satellites, with significantly higher specific impulse than that of chemical propulsion. In fact, some satellite development organizations have already applied it to their satellites, and the Japan Aerospace Exploration Agency (JAXA) is also developing a new all-electric geostationary communication satellite equipped with Hall-effect thrusters. One disadvantage of electric propulsion is that its thrust force is much smaller than that of chemical propulsion. Although the thrust force of a Hall-effect thruster can be relatively high compared to other electric thrusters, it is generally one-tenth to one-hundredth of the thrust force of chemical propulsion. Consequently, the transition time from injected orbit to geostationary orbit is much longer, which can be recognized as greater operational risk and higher cost. The thrust force of a Hall-effect thruster can be somewhat improved by increasing its discharge power and voltage. However, this design decision not only increases the satellite bus mass but also deteriorates the specific impulse, resulting in drastically decreased payload mass. Therefore, the balance between payload mass and transition time entails critical decision-making to achieve a satellite's competitiveness in the market. This study examines the trade-off between payload mass and transition time in the all-electric geostationary communication satellite based on Hall-effect thrusters from a multidisciplinary perspective, including the thruster design, injection orbit, satellite mass, and power supply design. Overall satellite system design, including the satellite's injection orbit, is separately optimized under certain constraints as maximizing the payload mass or minimizing the transition time. Pareto frontiers are also investigated as gradually changing the weighted factors of both objectives. Finally, the non-dominant and competitive system design is discussed in comparison with the existing same type of all-electric satellite.


Background and Objective:Oxygen-derived free radicals (OFRs), produced as myocardium is reperfused after ischemic injury, contribute to reversible and irreversible cellular injury. KATP channels, activated by ischemia, have been reported to participate in the arrhythmogenic response to acute myocardial ischemia. Therefore, we examined the effects of OFRs on the regulation of KATP channel activity. Materials and Methods: Isolated mice (ICR) hearts were perfused with Tyrode's solution on a Langendorff apparatus. Single ventricular myocytes were isolated using enzymatic digestion with collagenase and protease. Single channel currents in the inside-out patch mode were recorded. OFRs were applied by mixing hypoxanthine and xanthine oxidase. The currents were recorded in the patch membrane at a holding potential of -60 mV. Results:OFRs generated by 0.1 U/mL xanthine oxidase and 0.5 mM hypoxanthine had no effects on the activities of KATP channels before and after treatment with 200 μM ATP. OFRs generated with 0.2 U/mL xanthine oxidase and 1.0 mM hypoxanthine reactivated the channel activities which had been attenuated by 100 μM ATP. In the presence of 100 U/mL superoxide dismutase and 122 U/mL catalase, which are OFRs scavengers, OFRs did not affect the KATP channels activities. Conclusion:OFRs generated by the reaction of hypoxanthine and xanthine oxidase increased the KATP channel activities in the inside-out patch. (Korean Circulation J 2003;33 (12):1140-1146)


Abstract The purpose of this paper is two-fold: Firstly, it reports on one man's experience of bulimia. After being interviewed it became evident that he did not meet the inclusion criteria for the study, which was focussed on anorexia in men. Secondly, the paper explores the implications for a novice researcher of including someone in a study who does not meet the inclusion criteria. The researcher's story reflects upon the implications of self-doubt when embarking upon sensitive research, and the morality of holding onto a rogue participant's story. It offers others an opportunity to consider and learn from this experience.

Comparison with the test results shows that the present method is feasible to use in engineering.


Physical chemists studying the way molecules move need no longer rely exclusively on indirect spectroscopic techniques to provide the essential data for their models – molecular vibration and rotation spectra. In a recent letter to Nature (1990 343 737), Ahmed Zewail and his colleagues at the California Institute of Technology, Pasadena, USA, report their first observations of molecular motions in real time achieved using two variable wavelength lasers capable of delivering 60 fs light pulses (1fs = 10-15S). These elegant experiments indicate that femtosecond transition state spectroscopy (FTS) – previously confined to studies of molecular dissociations – is even more versatile than first thought.

Breast wall effect of double-pipe protecting borehole wall blasting and its functional mechanism are studied.Comparing with regular borehole wall blasting,the average decreasing rate of shock waves in double-pipe protecting borehole wall blasting test is 1.45%,and the common smoothing blasting is(4.83%),which proved the superiority of double-pipe protecting borehole wall blasting technology in directional blasting.The results show that double-pipe protecting borehole wall blasting can be used to protect reserved rock by double-pipe,and to avoid blasting damnification under shock wave and burst gas.The applications of it in the front site construction engineering of Dragon No.16 oil and gas well drilling,prove the low damage of rock and good effect of breast wall.


The author considers the problem of compressing the digital devices' diagnostic information when performing testing procedures. The solution method is based on finding integer solutions of simultaneous linear algebraic equations (SLAE). Previously, there were no other solution methods for this problem except for enumeration. The article developed a genetic algorithm (GA) using a special fitness function to solve simultaneous linear algebraic equations. It makes an effective selection of individuals in the genetic algorithm when forming the next generation and thus accelerates the search for solutions to the combinatorial problem under study.


This paper aimed at the problem that it is impossible to evaluate the depths of the surface-breaking defect of austenitic stainless steel pressure pipes using the Magnetic Particle Testing(MT) and Penetration Testing(PT) methods. A quantitative method for measuring the depths of the surface-breaking defect of austenitic stainless steel pressure pipes based on eddy current array testing (ECAT) was proposed. According to the imaging features of defective ECAT correlation, by analyzing the change trend of the color, impedance amplitude and impedance phase of the C scanning, the corresponding relationship between the depth of the defect can be established, and finally, the effective evaluation of the depth of the opening defect on the surface of the material can be realized. Simulation and experimental results verify the effectiveness and reliability of the proposed method.


This paper covers the application of a model-based engine control (MBEC) methodology featuring a self tuning on-board model for an aircraft turbofan engine simulation. The nonlinear engine model is capable of modeling realistic engine performance, allowing for a verification of the advanced control methodology over a wide range of operating points and life cycle conditions. The on-board model is a piece-wise linear model derived from the nonlinear engine model and updated using an optimal tuner Kalman Filter estimation routine, which enables the on-board model to self-tune to account for engine performance variations. MBEC is used here to show how advanced control architectures can improve efficiency during the design phase of a turbofan engine by reducing conservative operability margins. The operability margins that can be reduced, such as stall margin, can expand the engine design space and offer potential for efficiency improvements. Application of MBEC architecture to a nonlinear engine simulation is shown to reduce the thrust specific fuel consumption by approximately 1% over the baseline design, while maintaining safe operation of the engine across the flight envelope.


This paper presents in service performance for seven regional and major international airports in the UK, covering different performance related runway surface courses, from the time of installation to in service. The wet friction monitoring at these airports was carried out by using Continuous Friction Measurement Equipments (CFME) over 6 years in service. Longer temporary total ungrooved runway lengths have been successfully adopted at several UK airports where the authors were involved in the resurfacing work, without any issue associated with the early-life surface friction; this resulted in early completion, reduced airfield down time and cost saving. Records to date, demonstrating the ability of well-designed surfacing material to maintain very good friction characteristics since the opening of the runways, are also presented.


The presently paver block is used in flooring versatility application and also it is used in street road and other construction places. For improving compressive strength and other parameter of paver block this study is necessary. By addition of polypropylene fibers in paver block it increases the compressive strength of paver blocks and reduces the maintenance cost of paver block. Also it's helpful to improve the life span of paver block. In this paper represent the results of the concrete paver block with the mix proportion of 1:3 (Cement: dolomite powder) in the top layer of paver block and 1:1:2:3.75 (Cement: fine aggregate: semi grit: Quarry dust) in the bottom layer of paver block. In both layer additions of polypropylene fiber (PPF) by 0.1%, 0.2%, 0.3%, 0.4%, 0.5% in each mix proportion. The compressive strength and water absorption has been obtained with the inclusion of PPF in paver block. Test results indicate that by the addition of PPF by 0.4% it gives maximum strength at 7, 14, 28 days and minimum water absorption. The paper also shows the cost comparison for the each mix proportion.


Monoclonal antibody subplate‐l (mAb SP1) specifically stains somata, dendrites and axons of spiny inverted pyramidal neurons in the subplate zone in the early postnatal kitten neocortex. The SP1 antigen has been previously identified as a cytosolic protein of apparent molecular weight 56 kDa. We have now employed immune‐affinity chromatography to further characterize this antigen. An antigen with SP1‐like immunoreactivity (ir) is present in various organs, and is particularly enriched in blood plasma. Exsanguination of the organs prior to protein extraction reduces the SP1‐ir band dramatically, indicative of a blood‐borne molecule. The 56 kDa SP1‐ir antigen was purified from plasma by affinity chromatography and subjected to Edman degradation. The first 20 N‐terminal amino acids show 80% homology to the N‐terminus of immunoglobulin heavy chain of man, the mouse and the dog. If the 56 kDa SP1‐ir antigen in plasma is an immunoglobulin, and if an immunoglobulin‐like molecule is present in the subplate, then antisera against cat immunoglobulins should stain subplate neurons. A polyclonal antiserum against cat IgG intensely stains the somata and dendrites of subplate neurons. On protein blots, this antiserum recognizes the 56 kDa band, and an additional band of ∼27 kDa, corresponding in size to immunoglobulin light chains. Preabsorbing mAb SP1 with cat immunoglobulin G abolishes the immunoreactivity in sections of kitten cortex. Further, it dramatically reduces the reactivity on protein blots. The results suggest that the 56 kDa SP1‐ir antigen in cortical subplate neurons belongs to the immunoglobulin superfamily.


I'm sorry, I'd really like to oblige but I cannot subject my precious paper to the brutal textual reductionism that is abstractisation. Aren't abstracts most interesting for all they don't say? Isn't an abstract merely a textual device of indexicality, shouting and pointing "here is a paper" just like the disingenuous "last petrol before motorway" signs one learns never to believe because they really meant "last petrol before motorway" (not counting the other six petrol stations after this one). All you need to know, fellow marketing academics, is that you simply must read this commentary because, hey, you're in it.


Recent reports of cancer registry data document an extremely high incidence of esophageal cancer but relatively low rates of stomach cancer in sub-Saharan Africa, with favorable trends in the latter.1,2 For example, in Malawi, with a 9% HIV prevalence, esophageal cancer (histologically verified in 24%, mainly squamous cell) was the second most common cancer in men and the third most common in women, with a peak rate at 65 years and older, similar age-specific rates in men and women, and higher age-adjusted rates than in other African registries and blacks in the United States.1 Because of a lack in comprehensive death registration, death rates were not available. Increases in the incidence of stomach cancer in recent birth cohorts between 1978 and 2007 were seen in Uganda.2 We examined mortality estimates from the Global Burden of Disease, Injuries, and Risk Factors Study 2015 (GBD2015) for the causes of these cancers in sub-Saharan Africa and the Caribbean.


Developing and implementing a remote lab based on FPGA can improve the teaching of Digital Electronics, giving students a web application to remotely test the designs proposed in practical sessions on real hardware. A server connected to the development system configures the programmable digital device with the proposed designs and allows the remote user to interact with the input and output peripherals. The server can manage connections and their time of use in order to avoid congestion of resources, and also allows usage statistics to be drafted.


The patch-clamp technique was used in the whole-cell configuration to study plasma membrane channels permeable to the diamine putrescine in protoplasts isolated from cultured cells of Arabidopsis thaliana 1. Under our experimental conditions, no channels selectively mediating putrescine influx were observed. lnward K+ channels showed a low permeability to putrescine, the permeability ratio,of putrescine relative to K+ being around 0.1. Further characteriiation of the previously identified outward channels mediating putrescine efflux (R. Colombo, R. Cerana, N. Bagni 119921 Biochem Biophys Res Commun 182: 1187-1192) indicated that their activity was regulated by the overall ion concentration of the external medium.


1
Ancrod is inactivated by diisopropyl [32P]phosphofluoridate when one g-atom of 32P is irreversibly bound to 34600 g enzyme.

2
Acid hydrolysis of the radioactive and inactive enzyme confirms that the label is attached to a serine residue in l-serine-O-[32P]phosphate.

3
Ancrod is inactivated by the substrate analogue α-N-(nitrobenzyloxycarbonyl)-l-arginyl chloromethyl ketone. Kinetic analysis shows that the irreversible inactivation is preceded by a reversible binding of inactivator to the enzyme. This inactivation is prevented by the addition of α-N-benzoyl-l-arginine ethyl ester.

4
The rate of inactivation of ancrod by the active-site-directed reagent depends on the ionisation of a group with pK(app) of 7.4. This group is probably the histidine residue which is lost when the enzyme is inactivated by this compound.

5
A modified figure of approximately 38000 is suggested for the molecular weight of the enzyme which contains one active site.


Abstract We prove that a polynomial map from R n to itself with non-zero constant Jacobian determinant is a stably tame automorphism if its linear part is the identity and all the coefficients of its higher order terms are non-positive. We also prove that the Jacobian conjecture holds for any number of variables and any field of characteristic zero, if one can show that every polynomial map of R n to itself is injective when it has a non-zero constant Jacobian determinant and has linear part the identity, and all the coefficients of higher order terms are non-negative. The proofs use special properties of matrices with non-positive off-diagonal elements and non-negative principal minors, and of matrices with vanishing principal minors. Furthermore we reduce the Jacobian conjecture to a polynomial matrix problem. Moreover, if the matrix has a positive answer, then every real polynomial automorphism is stably tame.


Lower quality of life (QOL) was observed among people with epilepsy than those free from it. Identification of factors influencing QOL may be helpful in improving epilepsy care. Psychiatric morbidities have been shown to influence QOL adversely. This study aimed to determine the variables associated with QOL in patients with epilepsy free from psychiatric morbidities. Four hundreds patients attending a tertiary care hospital in Andhra Pradesh were recruited. QOL was measured using Telugu version of QOLIE89 (Quality of life 89) instrument. Mean of total QOL score was 42.30 ± 7.66(range 24-67). Those who were married, stayed in rural areas, not lettered, involved in agriculture and had low income levels (p<0.01) were found to have lower mean total QOL score. Multivariate regression analysis showed that previous exposure of knowledge on QOL, reaction to the diagnosis of epilepsy, stress in being alone and feeling of health getting worse were significant predictors of poor QOL in patients with epilepsy (p<0.01). Previous exposure of knowledge on QOL, response to the diagnosis of epilepsy, stress in being alone and feeling of health getting worse were significant predictors of lower quality of life among people with epilepsy.


With the growing integration of world economy and the deepening of economic globalization,heories of competitiveness,rising from 1980s,have been increasingly receiving extensive attention.Governments,academia and entrepreneurial organizations of each country are trying to,through in-depth research and practical applications,improve their level of competitiveness to deal with the complicated situations and to handle the intensive and complex challenges in the future.This paper,exploring the substantive content and the research value of the governmental competitiveness from the related concepts,is aiming to provide reference for the reform and development of the current government.


In the 12th century, along the borders of the Japanese state in northern Honshu, three generations of local rulers built a capital city at Hiraizumi that became a major military and commercial center. Known as the Hiraizumi Fujiwara, these rulers created a city filled with art, in an attempt to use the power of art and architecture to claim a religious and political mandate. In this study, the author studies the rise of the Hiraizumi Fujiwara and analyzes their construction programme. She traces the strategies by which they attempted to legitimate their rule and grounds the splendour of Hiraizumi in the desires, political and personal, of the men and women who sponsored and displayed the art.


Energy transport between molecules and surfaces plays an extremely important role in many chemical and physical processes. At the micro scopic level, molecules may be chemisorbed or dissociate on a substrate during a chemical reaction, they may undergo diffusion and desorption, or when adsorbed may change the physical or optical properties of the surface. Over the last few decades, breakthroughs in the development of sophisticated surface-sensitive techniques have occurred, making it pos sible to identify and characterize very detailed properties of these types of adsorbate-surface interactions ( 117). On the whole, these methods probe the static nature of surfaces and reveal information about the system on a relatively long (> I sec) timescale. When chemical transformations occur at interfaces, however, vibrational energy transfer can play a key role in determining the outcome of processes, whether thermal or caused by interactions with energetic laser (2-6), atomic (7), or molecular beams (810). To obtain a better understanding of these types of interactions, it is advantageous to perform direct measurements of adsorbate vibrational energy transfer. This chapter reviews advances made over the last few years to directly measure mode-specific adsorbate vibrational population or energy relaxation lifetimes (T1) with ultrashort pulsed (ca. 10-12 sec) laser techniques. We also refer to TJ studies for several molecules in solution


Forty-three cases of nonsurgically managed ulnar fractures in the horse were reviewed. Twenty-three per cent of the horses were euthanized, 44% survived but were unsound, and 33% of the horses were sound when surveyed 6 months to 11 years following fracture. Best results were obtained when treating distal semilunar notch fractures (70% sound). Prognosis was poorest for horses with fractures of the olecranon affecting the semilunar notch (0% sound).


Based on an investigation of the performance of 35 English majors in story-retelling and spontaneous speech tasks,we analyzed the influence of task type and language proficiency on learners' oral accuracy and complexity.Results show that: 1)task type has significant influence on oral accuracy;2)language proficiency has different impacts upon accuracy and complexity with significant influence on accuracy;and 3)there is no interaction between task type and language proficiency.


Pyelonephritis is common, but few studies of the clinical aspects of urinary tract infection have focused exclusively on pyelonephritis and there is little information available regarding the prevalence of antimicrobial resistance and the process of care for patients hospitalized with pyelonephritis. Records of patients hospitalized with acute pyelonephritis during a 2-year period were reviewed. Demographic data, comorbidities, results of urine and blood cultures, and data regarding antimicrobial therapy and the use of diagnostic imaging were recorded. The associations between bacteremia and demographic characteristics, infection with a resistant uropathogen, and the use and results of diagnostic imaging were examined. Most patients hospitalized for pyelonephritis were young women; however, 52.8% had some underlying chronic disease and 19.4% had a structural or functional abnormality of the urinary tract. Escherichia coli was responsible for 85% of infections; 26% of these isolates were resistant to trimethoprim-sulfamethoxazole. Ampicillin in combination with gentamicin was the initial therapy in most patients (70%). Bacteremia occurred in 53% of patients; no relationship between the risk of bacteremia and the demographic characteristics or infection with a trimethoprim-sulfamethoxazole-resistant isolate could be demonstrated. Bacteremic patients were less likely to undergo diagnostic imaging (58.1% vs. 81.5%, P = 0.04) but had a longer length of stay (5.8 vs. 3.7 days, P = 0.01).


Foresters in Poland have accepted the presence of coarse woody debris (CWD) in managed forests, but there is still a tendency to remove any diseased tree from the forest stand as soon as possible. Trees invaded by bark beetles or infested by pathogenic fungi are considered a threat to forest health. That approach is typical for timber-oriented forest management. In Poland, where multifunctional forestry is a declared policy in all forests belonging to the National Forests Enterprise, the rules for managing and protecting forest stands are uniform throughout the country. This does not allow some diseased or malformed specimens to be spared during forestry work as prospective habitat trees and as future sources of CWD. Without relaxation of the rules concerning sanitary cutting, it will be difficult to maintain or increase the current amount of CWD. There is no point in sparing diseased or injured trees in forest areas that are of no great value for recreation or conservation, where timber production is the priority, but in areas where recreation and conservation of biodiversity are of high value the rules should be changed to allow the number of habitat trees and the amount of CWD to increase. key wordS: coarse woody debris, forest management, habitat trees, near-natural silviculture, sanitary cuttings, timber production J.

Regional characteristics of summer precipitation of 97 weather stations in Tibetan Plateau are analyzed by using a rotated empirical orthogonal function,based on summer total precipitation(June~August) from 1961 to 2005.And then the relationships between the first four regional characteristics corresponding to other factors such as water vapor transport and the circulation feature in neighboring areas are explored by using NCEP/NCAR monthly mean reanalysis data in summer from 1961 to 2006.At last,the differences of water vapor transport and the circulation feature between flood and drought years are investigated.The results show that the summer precipitation in the southern part of Tibetan Plateau is opposite to the northern part,and there is a remarkable difference between them in water vapor transport and circulation feature.If the moisture from Indian Ocean and Bay of Bengal transporting to the north and the moisture from the West Pacific Ocean transporting to the east are strengthened,also the Ural blocking high is strong and the circulation pattern is \!+-+\" from low to high latitudesin East Asia,water vapor will converging in Tibetan Plateau,so the rain in summer will be more than normal.And,contrariwise,the precipitation will be less than normal.


This study examines the structure and contents of the various programs offered by the Cologne City Library in Cologne, Germany, and discusses its implications for the role of the changing public libraries in the era of the Fourth Industrial Revolution. The Cologne Municipal Library, which has continuously played a leading role in the education of German libraries since its opening, has been transforming itself to become a center for producing information and knowledge and developing culture in accordance with the dynamic era of the Fourth Industrial Revolution. Currently, the Cologne Municipal Library plays a role as a multi-cultural space in the community where local members can experience various cultures, such as movies, music and games, and create a culture, beyond the traditional functions of library collection and preservation. The program of the City Library in Cologne, Germany, will help to redesign the functions and roles of public libraries in Korea in the future, and plan library contents for local members. ■ keyword :∣4th Industrial Revolution∣Public Library∣Cologne Municipal Library in Germany∣Maker Space ∣Virtual Reality∣Multicultural Space∣ * 이 논문은 2016년 대한민국 교육부와 한국연구재단의 지원을 받아 수행된 연구임 (NRF-2016S1A6A9931352) 접수일자 : 2018년 02월 09일 수정일자 : 2018년 04월 13일 심사완료일 : 2018년 04월 20일 교신저자 : 김재웅, e-mail : firstname.lastname@example.com 한국콘텐츠학회논문지 '18 Vol. 18 No. 5 12


The most important tasks of the Bioinformatics of the simple of (DNA)and (RNA) and protein and the difficulties of the large size of the search , the Genetic Algorithms has been a ready for optimizing combinatorial problem and of next serious. That homologies exist and can be discovered and recognized is of central importance to comparative and evolutionary biology traditionally, homology assessment for both morphological and molecular data has been treated as a 2-step process involving the creation of a proposition of homology and then the hypothesis evaluation through the test of congruence in a phylogenetic analysis. The paper collect the all 2019 paper and review it in details we find the potential future directions.


The temple architecture from the Indian subcontinent follows a certain protocol, and the sculptural programme of the temples is in conjunction with the prescribed norms. The paper looks at the regional temple architecture of Orissa, specifically at the profusion of secular female imagery, in the form of alasa kanyas or 'indolent maidens' that adorn the Orissan temples. The imagery of these maidens has been discussed in the Orissan text on temple architecture, Shilpa Prakasha of Ramachandra Mahapatra Kaula Bhattaraka from c. 11th century CE, and is the primary source of contemporary information on the subject.


Background and Aim: Food is the fundamental need of human life and has nutrients that support growth and health. Gastrointestinal tract microbiota includes beneficial microorganisms which have therapeutic effects and are known as probiotics. The studies on appropriate probiotic strains have led to the separation and identification of specific metabolic byproducts of probiotics known as postbiotics. Materials and Methods In this review study, relevant data were collected by searching for the keywords of "probiotics, postbiotics, immune system, bioactivity, disease, health improvement, food and pharmaceutical industries" in the Web of Science, PubMed, Medline and Scopus databases. All articles related to experimental studies were included in the study and articles without full text were excluded. Results: The probiotics must maintain their survival against inappropriate growth conditions of the processing, storage, distribution, preparation, and digestive system so that they can exert their beneficial effects on health. Conversely, probiotic metabolites can successfully overcome these unfavorable conditions and maybe a good alternative to probiotics. Considering their specific chemical structure, safety, long shelf-life, and the fact that they contain various signaling molecules, postbiotics may have anti-inflammatory, immunomodulatory, antihypertensive, inhibitory effect on abnormal cell proliferation, and antioxidant activities. Conclusions: Postbiotics can mimic the fundamental and clinical role of probiotics, and due to their unique characteristics, they can be used in a delivery system (pharmaceutical/functional foods) to achieve health-promotion objectives and also prevention, and treatment of diseases.


Euplatyrhopalus tadauchii sp. nov. (Paussini, Platyrhopalina) is described based on specimens collected with flight interception traps and light traps in Kaeng Krachan National Park, Thailand.


We consider a mixed‐model assembly line (MMAL) comprised a set of workstations and a conveyor. The workstations are arranged in a serial configuration. The conveyor moves at a constant speed along the workstations. Initial units belonging to different models are successively fed onto the conveyor, and they are moved by the conveyor to pass through the workstations to gradually generate final products. All assembling tasks are manually performed with operation times to be stochastic. An important performance measure of MMALs is overload times that refer to uncompleted operations for operators within their work zones. This paper establishes a method to analyze the expected overload times for MMALs with stochastic operation times. The operation processes of operators form discrete time nonhomogeneous Markov processes with continuous state spaces. For a given daily production schedule, the expected overload times involve in analyzing the Markov processes for finite horizon. Based on some important properties of the performance measure, we propose an efficient approach for calculating the expected overload times. Numerical computations show that the results are very satisfactory. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007


The growing demand throughout the world for good quality soils to expand more profitable productive systems (crops, fruits and vineyards) is displacing forage crop production to marginal environments that often have soils with low fertility, pH problems, poor drainage and subject to periods of drought. The situation is similar in Chile, but the problem is exacerbated by the effects of global climate changes, with an estimated decline in precipitation of 40 percent and an increase of 2-4oC in continental temperature by the end of this century. In this context grasses are increasingly being cultivated beyond their limit to adapt in areas where the ability to tolerate environmental stresses is an essential characteristic for success. The breeding of forage Lotus species and other perennial forage legumes has historically presented low rates of genetic progress because of their genetic complexity. The majority of forage legume species are polyploid, cross-pollinated and self-incompatible. These characteristics make it necessary to use plant-breeding methodologies that are inefficient and very time-consuming. The most popular selection strategies have been masal and recurrent phenotypic selection. Neither strategy considers progeny tests, because they are not efficient in the selection of characters of low inheritability, such as dry matter production. As well, commercial cultivars are the products of many genotypes that generate heterogeneous combinations, which hinders evaluation and prediction of genetic merits. Consequently, strategies are essential to improve our understanding of the genetic components that determine the expression of phenotypic traits of agronomic and adaptive interest. The objectives of this review are to describe the work carried out by the National Institute for Agricultural Research (INIA) of Chile, and the methodologies and results of its work in selecting naturalized populations of forage legume species to develop a broad genetic base for breeding.


such a concept certain properties of creation follow, among which is the non-exclusion of moderate evolution. Given this definition, the fact of creation is treated. Here the first question is: is creation possible? Dr. Santeler answers: the concept contains no contradiction, and so creation is possible. Next the actual fact of creation is proved. Briefly, the argument runs as follows: Whatever does not necessarily (of itself, having the reason for its existence in its essence) exist, necessarily has a cause But the things of the world which change, do not necessarily exist, and therefore have a cause; for unchangeableness is a characteristic of necessary existence. In the things of our experience, which are caused, the matter from which they come to be cannot be eternal, because it is changeable and multiple. Hence it does not exist necessarily, and so is caused. Now, excluding the emanation of matter from God as impossible, we must conclude that matter is created. A discussion of the extent to which creative activity enters our world is followed by a few pages on conservation. The exemplary causality of God is next considered. Here Dr. Santeler is careful to exorcize the ghosts of any essences outside God, relics of an Avicennian metaphysic. When treating the question of the final cause of creatures and the motive for God's creating, the author insists that this can be only God's infinite goodness, and strenuously rejects the idea of extrinsic glory as a motive. He adds, of course, that creation necessarily glorifies God. With this understanding of creation the next step is to deduce its fruitful applications to human life. First, as regards man's knowledge of God: only with the knowledge of the fact of creation is our knowledge of God's existence and essence in a position to be complete. Then, for man and his life, the consequences are many: creation is a guarantee of the spirituality of the soul; it is the answer to man's "whence?" and "whither?"; it manifests the nobility of man; it portrays God as a Father and helps to render less acute the problem of the great amount of evil in the world. Finally, it aids in solving the existential problems of man. Readers will find Dr. Santeler's little book helpful and suggestive, even though they may feel forced to make reservations on certain points.


Src-kinase associated protein 2 (SKAP2) is an intracellular scaffolding protein that is broadly expressed in immune cells and is involved in various downstream signalling pathways, including, but not limited to, integrin signalling. SKAP2 has a wide range of binding partners and fine-tunes the rearrangement of the cytoskeleton, thereby regulating cell migration and immune cell function. Mutations in SKAP2 have been associated with several inflammatory disorders such as Type 1 Diabetes and Crohn's disease. Rodent studies showed that SKAP2 deficient immune cells have diminished pathogen clearance due to impaired ROS production and/or phagocytosis. However, there is currently no in-depth understanding of the functioning of SKAP2. Nevertheless, this review summarises the existing knowledge with a focus of its role in signalling cascades involved in cell migration, tissue infiltration and immune cell function.


The theme of this particular thesis is the study of the digital television via Internet protocol, also known as IPTV (Internet Protocol TeleVision) with special focusing on the decoder which is used in order to achieve television broadcasting. This decoder is called Set-Top Box. Essentially, IPTV is the transmission of television signals over broadband which is using IP protocol through a closed private network and not the public Internet. IPTV is considered to be the present and the future regarding the types of television because the user has the ability to access TV channels with digital view, while the ability provided by on-demand services about watching every type of television content at every time the user wants makes the whole "package" much more attractive.

Particularly, in this thesis, is firstly presented the definition of networking TV and generally of all these things which have contributed to the creation of IPTV. Following is a brief historical background to the events that led to the form of IPTV as we know it today. Afterwards, the IPTV is compared to the Internet TV, which is familiar to us. After that, a general description of an IPTV network is taking place and then we go further as technical details of such a network are described. Moreover, the encodings performed and their differences are mentioned. Additionally, there is much reporting and analysis in various types of decoders (Set-Top Box) used and marked the differences they have on their structure and their profile. Finally, there is a reference to IPTV packet providers in Greece and is happening a comparison among these packets.


Synthetic oligonucleotide probes based on amino acid sequence data were used to identify and clone cDNA sequences encoding a catalase (catalase‐R) of Aspergillus niger. One cDNA clone was subsequently used to isolate the corresponding genomic DNA sequences (designated catR). Nucleotide sequence analysis of both genomic and cDNA clones suggested that the catR coding region consists of five exons interrupted by four small introns. The deduced amino acid sequence of catalase‐R spans 730 residues which show significant homology to both prokaryotic and eukaryotic catalases, particularly in regions involved in catalytic activity and binding of the haem prosthetic group. Increased expression of the catR gene was obtained by transformation of an A. niger host strain with an integrative vector carrying the cloned genomic DNA segment. Several of these transformants produced three‐ to fivefold higher levels of catalase than the untransformed parent strain. Hybridization analyses indicated that these strains contained multiple copies of catR integrated into the genome. A second expression vector was constructed in which the catR coding region was functionally joined to the promoter and terminator elements of the A. niger glucoamylase (glaA) gene. A. niger transformants containing this vector produced from three‐ to 10‐fold higher levels of catalase‐R than the untransformed parent strain.

This study examines the impact of demographic change and urbanization on economic growth in Indonesia from 1960-2007. The analysis shows that economic growth is positively related to both the level and the rate of change of the working age population. Economic growth is also positively associated with the level of urbanization. But increases in the rate of urbanization negatively affect growth; in fact, they swamp the positive level-effects. The decreasing primacy of Jakarta also has a negative impact on economic growth. All things considered, Indonesia appears to be adapting well to the momentous changes in demographics that it is experiencing. But the country must rethink its approach to urbanization with a view to realizing the potential agglomeration economies that have apparently accrued to other countries during the course of development. In order to do this, the public sector will have to significantly increase its investment in urban infrastructure.


Following the protest demonstrations of the 2011–2012 electoral cycle, tensions between the limited modernization efforts of Medvedev and the resurgent authoritarianism of Putin have become increasingly manifest. These are seen not only in the relationship between society and the state, but also in the "para-constitutional" institutions of the dual state. This article argues that whereas Medvedev created an arena for liberalization within these para-constitutional structures, Putin has firmly rejected these policies, among other things by revising the 1995 law on NGOs amended in 2006. Using the perspective of the dual state, the article argues that with the introduction of the Law on Foreign Agents (2012), the original law draft On Public Control (2014), a key element in Medvedev's modernization program, was delayed and substantially altered. Together, these amendments create precarious conditions for NGOs, pressuring their independence by threats of dissolution and reducing the quality of civil control over state organs.


Nonlinear vibrations of composite plates on an elastic foundation in thermal environments are presented in this study. Graphite/epoxy is selected as the plate material. The properties of composite material are assumed to be temperature-dependent. Nonlinear free vibrations of laminated composite plates are investigated in the fully clamped boundary conditions. The classical finite element method is used and a specially prepared computer code is written in the Matlab software. Vibrations of the spring supported laminated composite plate are directly influenced by the boundary conditions and dimensions of plate.In this study, generated graphical values reveal that foundation stiffness and temperature have significant effects on the linear and nonlinear frequencies of composite plates.


This paper distills the many forms or expressions of nationalism associated with the Olympic Games into four historical themes: the Olympic athlete, or team, as a tangible representation of the nation incarnate; the symbolic value of victories and medals; the diplomatic significance of recognition in the International Olympic Committee; and the political currency of hosting an Olympic festival.


The possibility of using an aqueous stratified system of antipyrine — sulfosalicylic acid — water for the selective isolation of scandium macro- and microquantities for subsequent determination is studied. The proposed extraction system eliminates the usage of toxic organic solvents. The organic phase with a volume of 1.2 to 2.0 ml, resulting from delamination of the aqueous phase containing antipyrine and sulfosalicylic acid is analysed to assess the possibility of using such systems for metal ions extraction. Condition necessary for the formation of such a phase were specified: the ratio of the initial components, their concentration, presence of inorganic salting out agents. The optimum ratio of antipyrine to sulfosalicylic acid is 2:1 at concentrations of 0.6 and 0.3 mol/liter in a volume of the aqueous phase of 10 ml. The obtained phase which consists of antipyrinium sulfosalicylate, free antipyrine and water, quantitatively extracts macro- and microquantities of scandium at pH = 1.54. Macro- and microquantities of yttrium, terbium, lanthanum, ytterbium and gadolinium are not extracted under the aforementioned conditions thus providing selective isolation of scandium from the bases containing yttrium, ytterbium, terbium, lanthanum, and gadolinium.


In this review we evaluate definitions of bilingualism, its nature and scope, and types of bilinguals. We indicate the importance of assessing the degree of bilingualism accurately, and delineate some of the difficulties associated with evaluating it. We discuss bilingualism and biscriptalism, and reading different orthographies. Finally we place these issues within the context of English — Afrikaans bilingualism in South Africa.


Objective: To investigate the effects of the fl ower essences impatiens, cherry plum, white chestnut and beech in anxious people. Methods: A quantitative, randomized, double blinded study. Data were collected between May and August, 2010, with 34 employees of the Center for Improvement of Health Sciences of the Zerbini Foundation. Anxiety was assessed using the Diagnostic Inventory of State Trait Anxiety at two different times, at the beginning and end of the intervention. Results: As a result it was observed that the group that used the fl ower essences had a larger and statistically signifi cant reduction in anxiety level in comparison to the placebo group. Conclusion: We conclude that fl ower essences have a positive effect on the reduction of anxiety.


The connection between the Wigner distribution and the squared modulus of the fractional Fourier transform which are both well-known time-frequencyrepresentations of a signal - is established. In particular the Radon-Wigner transform is used, which relates projections of the Wigner distribution to the squared modulus of the fractional Fourier transform. Moments of the Wigner distribution are then expressed in terms of moments of the fractional Fourier transform. Relations for the fractional Fourier transfork moments are derived, and some new procedures are presented with the help of which Wigner distribution moments can be determined by using the fractional Fourier transform.


How are transactions conducted on Georgian consumption market and the European Union internal market? During exportation of some agro products from Georgia to the EU it was found out that relevant trade habits in making a deal varies greatly for the 'two Economies' and the difference is significant. Apparently, this makes an issue for present-day commerce and, presumably, the disparities, which have just been noted, risk to pose a serious threat to trade relationships between the two economic Units. Therefore, this Article aims at looking around the differences. I will attempt to explain the flexibility of the contemporary 'simplified-type transactions' conducted in the EU, characterized by disappearance of traditional formal stages of contracting (negotiations, contract-signing, etc.). In this Article, I will also show out that these relationship-building (stemming from the 'brand-new transactions') is more consecutive, logical and dynamic, leaving less room for the breach of a contract or principle of good faith.


Background: Hearing is necessary for the development of language, speech, and cognitive skills. Hearing loss effects a child's ability to learn, communicate, and to socialize. Hearing impairment often goes unnoticed which compromises a child's ability to speak and express their needs. If no rehabilitation is done child develops physical and mental issues. Deaf-mute children are neglected in these aspects hence present study aimed to assess their nutritional and morbidity status among them. The objective of this study was to assess the morbidity profile among Deaf mute children attending organizations in Hyderabad and to determine their nutritional status among them.
Methods: A cross-sectional study was conducted over for 2 months during May and June 2022 among 50 deaf-mute children attending a special school in Hyderabad. A pre-designed semi-structured questionnaire was used to interview subjects after taking permission from the principal and confidentiality was ensured. The collected data were analysed using MS Excel and Epi-Info software.
Results: The mean age was 13.4 years with the majority being female children (82%). The prevalence of undernutrition was 16% and the prevalence of overnutrition was 26%. The prevalence of undernutrition was more among boys and the prevalence of overnutrition was slightly more among girls. The morbidity pattern showed that 24 (47.5%) suffered from any disease during the past 3 months with the commonest morbidity being dental caries (74%).
Conclusions: The study showed a high proportion of deaf-mute children developing nutritional deficiencies and morbidities; hence an effective collaboration and coordination between these organizations and ICDS anganwadi centres are needed for the improvement of nutritional status.


A 69-year-old man was admitted to our hospital for abdominal pain. An abdominal computed tomography(CT)scan revealed pancreatictail cancer with peritoneal dissemination. We administered systemic chemotherapy consisting of S-1 and gemcitabine. After 10 courses, the peritoneal dissemination had disappeared and tumor marker levels returned to almost normal values. Thus, we considered the patient to have an effective response, so we performed a distalpancreatectomy and partial resection of the stomach, transverse colon, and left adrenal gland. Eleven months after the operation, the patient is alive with no recurrence.


In CNC heavy cutting servo system, mechanical drive system has a torture feedback on electrical speed-adjustment system, thus it's possible to generate the mechanical resonance. The mechanical resonance makes the feature parameters of mechanical drive system influence the dynamic performance of the electrical speed-adjustment system. This paper has studied the resistance ratio and q parameters, and put forward the method to decrease the mechanical resonance influence.


Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue tumor with a low malignant potential and a high local recurrence rate after surgical excision (1). DFSP can be found anywhere on the body, but is often found on the chest and shoulders (1). DFSP arises in the dermis and invades deeper tissues such as fascia, muscle and bone (1, 2). Due to its tendency for local invasion and asymmetric spread, DFSP in the perianal area can extend to the anal sphincter and show similar imaging findings to those of a malignant tumor arising from the anorectal fistula. However, DFSP in the perianal area is extremely rare, and only one case has been reported in the English medical literature (3). To the best of our knowledge, there is no report regarding the detailed imaging findings of DFSP radiologically mimicking mucinous adenocarcinoma arising from the anorectal fistula. We present an extremely rare case of perianal DFSP mimicking mucinous adenocarcinoma arising from fistula in ano, and focus on the CT and MR imaging findings. This report was approved by the ethics committee at our institution, and the requirement for informed consent was waived.


The final aim of this research is to find out the competence, the knowledge and the regulation that future teachers show about their written expression. Writing processes identified by Hayes and Flower (1980) are studied in this paper, namely, writing plans, transcription, review, and metacognition or self-regulation. Data was collected through a semi-structured cognitive interview, which included a valid and standardized survey


We investigated ovarian steroidogenic enzyme gene expression in exogenous androgen induced polycystic ovaries (PCO) in rabbits. Twelve 3-month peripubertal, and seven 9-11 month reproductive aged New Zealand White female rabbits were divided into four treatment (Rx) groups: controls receiving saline only, testosterone (T) treated (6-10 mg/Rx), LHRH analog (L) treated (leuprolide depot 1.0-1.2 mg/Rx), and T plus L treated (T+L). Animals in each group were administered the treatment IM every 2 to 3 weeks for 12-14 weeks. Serum T levels (every 1-3 wks) in T (127 ± 29 ng/dl) and T+L treated (144 ± 27 ng/dl) groups during the treatment period were unequivocally higher than the levels in controls (16 ± 6 ng/dl) and L treatment (22 ± 4 ng/dl) groups. Serum E2, LH and FSH levels (every 1-3 wks) showed no discernable differences between the groups. Microscopic examination of the L, T+L and T treated rabbit ovaries revealed a spectrum of PCO changes in comparison to the age-matched control ovaries, depicting marked interstitial hypercellularity and large cystic follicles in all except markedly decreased immature follicles and a few small cystic follicles in T treated peripubertal rabbits. Ovarian P450 cholesterol side-chain cleavage (P450scc) and 3β-hydroxysteroid dehydrogenase (3β-HSD) mRNA and protein levels in PCOs of T and T + L treated animals were similar to the age-matched control ovaries, while in L treated PCOs both P450scc and 3β-HSD mRNA and protein levels were increased. Thus excess T alone did not alter the ovarian steroidogenic enzyme gene expressions despite the morphology changes. The L treatment alone had a gonadotropin agonistic effect resulting in both PCO and increased ovarian steroidogenic enzyme gene expression. However, excess T abolished the L-mediated increased ovarian steroidogenic enzyme gene expression, indicating the presence of an inhibitory effect of T on L induced ovarian steroidogenic enzyme gene expression. These findings suggest that the pathogenic mechanism by which PCO is induced by extra-ovarian source of T differs from that induced by increased gonadotropic effect alone.


Generic matrix multiplication (GEMM) and one-dimensional discrete convolution/cross-correlation (CONV) kernels perform the bulk of the compute- and memory-intensive processing within image/audio recognition and matching systems. We propose a novel method to scale the energy and processing throughput of GEMM and CONV kernels for such error-tolerant multimedia applications by adjusting the precision of computation. Our technique employs linear projections to the input matrix or signal data during the top-level GEMM and CONV blocking and reordering. The GEMM and CONV kernel processing then uses the projected inputs and the results are accumulated to form the final outputs. Throughput and energy scaling takes place by decreasing the number of projections computed by each kernel, which in turn produces approximate results, i.e. lowers the precision of the performed computation. Existing realizations of error-tolerant multimedia applications can opt to utilize a small number of the input projections (typically just one) in order to save energy and processing cycles, while all error-intolerant systems can compute all input projections and obtain full-precision outputs. Results derived from a voltage- and frequency-scaled ARM Cortex A15 processor running face recognition demonstrate that the proposed approach allows for 5-fold to 10-fold increase of processing throughput and more than 80% decrease of energy consumption against optimized GEMM and CONV kernels without any impact in the expected recognition and matching precision.


We analyze the efficiency of indexing executive pay by calibrating the standard compensation model to a large sample of U.S. CEOs. The benefits from indexing the strike price of options are small, and fully indexing all options would increase compensation costs by 50% for most firms. Indexing has several effects with overall ambiguous outcome; the quantitatively most important effect is to reduce incentives, because indexed options pay off when CEOs' marginal utility is low. The results also hold if CEOs can extract rents and extend to the case of indexing shares. Our findings may justify the common practice of "pay-for-luck." The Author 2013.

The buoyant density titrations of five ionizable copolypeptides in concentrated CsCl solutions have been determined. The results are used to formulate models for predicting the buoyant density titration behavior of copolypeptides and proteins using the previously reported homopolypeptide buoyant density titration curves. It was determined for these copolypeptides that the best predictive model must include not only the buoyant densities of the constituent amino acid residues and the relative composition, but also hydration and salt binding.

AbstractAcid Blue 256 (AB256) dye was selected as the model. Textile effluents and linear and nonlinear regression procedures have been applied to the Langmuir, Freundlich, Tempkin, Dubinin–Radushkevich, and Redlich–Peterson isotherms for adsorption of the dye onto red pine (Pinus resinosa) sawdust. The effects of parameters were investigated and interaction was characterized by Fourier transform infrared (FTIR) spectroscopy and SEM/EDAX. Five isotherms were used, and the nonlinear method of the Langmuir isotherm equation was found to provide the closest fit to the equilibrium data. The monolayer adsorption capacity is 54.16 mg/g for AB256. The optimum conditions were found to be: adsorbent size 75–90 μm, initial pH 2, stirring rate 600 rpm, initial dye concentration 200 mg/l, biosorbent dose 1 g and temperature 25°C. All thermodynamic parameters suggested that AB256 adsorption onto red pine sawdust was a spontaneous, physisorption, and exothermic process. Kinetics was analyzed by four different kinetic e...


Bullying generally has a negative impact on the victim's mentality. Victims of bullying have a negative impact on themselves and the environment if not addressed immediately. Family functioning is one of the factors that can minimize the occurrence of bullying. Through problem solving coping, children imitate what parents usually do in solving a problem. This research uses descriptive qualitative methods, using interviews and observations as data collection techniques. The results of this study indicate that problem solving in the family plays an important role in family functioning, along with the selection of coping strategies used in solving a problem. Coping strategies used by a child are innate constructs from parents and tend to be stable over time.


A survey of married women in Glen Norah Township, a new suburb southwest of Salisbury, Rhodesia, was conducted in February, 1977. The survey sought to answer 3 questions: what is the fertility pattern compared to other areas; how extensive is family planning practice; and, what sociological factors distinguish family planning practitioners for others. 799 women who had had 2501 live children were interviewed; their overall fertility rate was 29.4%. The fertility pattern is similar to that of the Dominican Republic in 1970. 563 women had never practiced family planning; 91 women had been practicing for at least a year. The remaining women had 33.2 births the previous year per 100 women, therefore the 91 family planners averted 30 births, 1 for every 7.8 born. Those who practiced family planning were better off socioeconomically and had better child survival rates than those who did not practice. Nonplanners, however, were not producing children in ignorance but were planning to bring their family size up to a reasonable level.


In this article, some considerations on the object of crimes related to the property interests of civil servants are studied and analyzed in detail. A special object of crimes related to the property interests of a civil servant should be considered social relations that ensure the normal functioning of the state mechanism.Crimes related to the property interests of a civil servant, in turn, have been analyzed by studying the work of a number of scholars as to whether they harm certain social relations prohibited by the CC or pose a real risk of such damage.


Sandis is an operation analysis tool which has been created in Finnish Defence Forces Technical Research Centre (PVTT) since the year 2002 and with co-operation with FFI since 2006. It can be used for cost-effect and tactical analysis from platoon to brigade level and is used in PVTT. The man in the loop is responsible for tactical decisions and Sandis calculates combat losses, ammunition consumption and medical evacuation process. Sandis is based on state machines, Markovian combat modelling and has fault tree analysis for combat operation success probability calculations. The results from Sandis are the strength distributions of the units and operation success probability as well as a killer –victim –scoreboard and medical situation average values. Weapon models are based on peace-time field tests and literature.


With steady improvement and standardisation of methods, nerve conduction studies have become a reliable means of testing peripheral nerve function. They supplement clinical observation by precisely localising the lesion and characterising the conduction abnormalities. Delineating the extent and distribution of the neural lesion by this means also helps to quantify the degree of involvement. Optimal results can be expected only with proper choice of techniques, which in turn depends on the type of lesions under consideration. Thus, the studies must be conducted as an extension of the clinical examination, rather than a laboratory test. To document sequential changes for clinical follow up in general and for drug trials in particular, conduction studies must yield high sensitivity and reproducibility. A question often posed, but rarely tested in regard to these criteria relates to the length of the nerve segment under study. Other factors being equal, should shorter or longer segments be studied for better results?


Introduction Drought is one of the most important constraints to bean production in East, Central and Southern Africa. Over 396,0001 of grain are lost annually in Africa due to drought (Wortmann et al, 1998). Drought may occur early in the season, mid-season or late in the cropping season. Drought is ranked as major constraint to bean production in Kenya, Ethiopia, parts of south western Uganda, northern and central Tanzania^ South Africa, southern Rwanda, Sudan, Angola, central plateau of Madagascar and southeast DR Congo. Although the adverse effects of drought can be alleviated through irrigation, few smallholder bean growers in East and Central Africa (except in Sudan) have access to irrigation water. Bean production in this region is predominantly rain fed. Crop failures are frequent. Growing drought tolerant bean cultivars is probably the most cost-effective strategy for smallholder, resource-poor farmers in drought prone environments. However, few drought tolermt cultivars are available in sub-Saharan Africa. CIAT has been screening bean cultivars for drought since 1983 (Laing et al, 1983) as part of integrated genetic improvement of the common bean (Teran and Singh, 2002). Recently, an international drought nursery was constituted which included the most promising drought tolerant lines. This report highlights the performance of this nursery in trials conducted in Eastern Africa.


AbstractOver the past two decades, plastic constraint effects have been an issue of concern in both fracture mechanics and structural integrity research, and several methods have been proposed for considering loss of plastic constraint. This paper shows the ability of a simplified model to predict brittle fracture under low plastic constraint conditions. Fracture toughness tests are performed on single-edge notched bend (SENB) steel specimens with deep and shallow notches, as well as on double-edge notched tension and center-notched tension (CNT) specimens. When compared with SENB specimens with a deep notch, the CNT specimens show high fracture toughness as a result of the loss of plastic constraint at the crack tip. Here, the Weibull stress approach and a toughness scaling model (TSM) are used to consider the effects of the loss of plastic constraint on the fracture toughness of the specimens. The corrected fracture toughness values evaluated by the TSM are found to be close to the toughness values obse...

Creativity is the ability of a person to give birth to something new, both in the form of ideas and real works that are relatively different from what has been there before. The process of student creativity usually begins with an example of the teacher's creative process. Being a creative, professional and fun teacher is required to have the ability to develop approaches and choose effective learning methods. Art learning is a business process carried out by a person to obtain a change in attitudes and behavior as a result of artistic experience and interacting with environmental culture to achieve certain goals. By Developing Student Creativity Through the Potential of Local Culture in Learning Dance Arts Tanjung Raja High School 2 is expected to get to know more about the culture around it and be able to increase creativity in art education.


The current limitations of qubit-based processors are caused by imperfections in quantum gates, leading to a lack of gate fidelity. Gate fidelity can be refined by extending the coherence of qubits and reducing logic operation speed. A potential solution is to develop a hybrid qubit that has the coherence of electrically-controlled quantum dots and the gate speed of their opticallycontrolled counterparts. Quantum bits that utilize ultrafast optical gating to perform gate operations require precise control of the gating pulse duration. Optical dispersion can cause adverse effects pulse duration, such as pulse broadening, so dispersion-compensation techniques must be employed; by properly managing dispersion in the gating pulses, the desired pulse durations can be obtained. This thesis presents the theory behind optical manipulation of quantum dots, proposed device designs based on ambipolar quantum dots, and a common method for measuring ultrashort laser pulses based on intensity autocorrelation.
